Definitions
- the ability to modulate an immune response is beneficial in a variety of clinical situations, including the treatment of cancer and pathogenic infections, as well as in potentiating vaccine responses to provide protective immunity.
- a number of therapeutic tools exist for modulating the function of biological pathways and/or molecules that are involved in diseases such as cancer and pathogenic infections. These tools include, for example, small molecule inhibitors, cytokines and therapeutic antibodies. Some of these tools function through modulating immune responses in a subject, such as cytokines that modulate the activity of cells within the immune system or immune checkpoint inhibitor antibodies, such as anti-CTLA-4 or anti-PD-L1 that modulate the regulation of immune responses.
- vaccines have long been used to stimulate an immune response against antigens of pathogens to thereby provide protective immunity against later exposure to the pathogens. More recently, vaccines have been developed using antigens found on tumor cells to thereby enhance anti-tumor immunoresponsiveness.
- antigen(s) used in the vaccine other agents may be included in a vaccine preparation, or used in combination with the vaccine preparation, to further boost the immune response to the vaccine.
- agents that enhance vaccine responsiveness are referred to in the art as adjuvants.
- Examples of commonly used vaccine adjuvants include aluminum gels and salts, monophosphoryl lipid A, MF59 oil-in-water emulsion, Freund's complete adjuvant, Freund's incomplete adjuvant, detergents and plant saponins. These adjuvants typically are used with protein or peptide based vaccines.

- RNA immunomodulatory therapeutic compositions including mRNA compositions
- the therapeutic efficacy of these RNA compositions has not yet been fully established.

- KRAS is the most frequently mutated oncogene in human cancer ( ⁇ 15%). Such KRAS mutations are mostly conserved in a few “hotspots” and activate the oncogene.
- the immunomodulatory therapeutic compositions of the invention include activating oncogene mutation peptides, such as KRAS mutation peptides.
- oncogene mutation peptides such as KRAS mutation peptides.
- Prior research has shown limited ability to raise T cells specific to the oncogenic mutation. Much of this research was done in the context of the most common HLA allele (A2, which occurs in ⁇ 50% of Caucasians). More recent work has explored the generation of specific T cells against point mutations in the context of less common HLA alleles (A11, C8). These findings have significant implications for the treatment of cancer.
- Oncogenic mutations are common in many cancers. The ability to target these mutations and generate T cells that are sufficient to kill tumors has broad applicability to cancer therapy.

- HLA class I molecules are important for establishing an immune response by presenting endogenous antigens to T lymphocytes, which initiates a chain of immune reactions that lead to tumor cell elimination by cytotoxic T cells. Altered levels of production of HLA class I antigens is a widespread phenomenon in malignancies and is accompanied by significant inhibition of anti-tumor T cell function.
- the generation of cancer antigens that elicit a desired immune response (e.g. T-cell responses) against targeted polypeptide sequences in immunomodulatory therapeutic development remains a challenging task.

Through the use of the technology of the invention, it is possible to elicit a desired immune response by selecting appropriate activating oncogene mutation peptides and formulating the mRNA encoding peptides for effective delivery in vivo.
- the immunomodulatory therapeutic compositions provide unique therapeutic alternatives to peptide based or DNA vaccines.

- KRAS KRAS relays external signals to the cell nucleus and contributes to regulation of cell division.
- Activating mutations in the KRAS gene impair the ability of the KRAS protein to switch between active and inactive states.
- KRAS activation leads to cell transformation and increased resistance to chemotherapy and biological therapies targeting epidermal growth factor receptors.
- KRAS amino acid sequence is provided below (UniProtKB P01116). KRAS mutations are common in many cancers, and G12 is the site of most common KRAS mutations.
- N-RAS proteins are highly prevalent in certain types of cancers and are useful as cancer vaccines. For instance, 29% of Cutaneous Melanoma involves a RAS mutation, of which 94% are of N-RAS origin. This represents about 2,500 new US cases/year of the most aggressive form of melanoma accounting for the majority of melanoma deaths. (Channing Der, Are All RAS Proteins Created Equal in Cancer?, Sep. 22, 2014, cancer.gov). There are 30,280 news cases of multiple myeloma annually, of which 26% are NRAS*. This represents ⁇ 6,100 new NRAS* cases per year. Thus, the N-Ras vaccines described herein are useful in some embodiments in the treatment of melanoma and multiple myeloma as well as other malignancies that harbor NRAS mutations.

- HPV E6 and E7 are viral oncogenic proteins whose expression is vital for the transformed phenotype, like mutant KRAS. Accordingly, HPV E6 and E7 are suitable model antigens because, similar to mutant KRAS, they are oncogenic drivers.
- each antigen contains a single missense mutation relative to its wild-type counterpart which is likely to be more challenging to recognize as “non-self” by the immune system than a viral antigen and (2) they are concatemerized.

- An epitope also known as an antigenic determinant, as used herein is a portion of an antigen that is recognized by the immune system in the appropriate context, specifically by antibodies, B cells, or T cells.
- Epitopes include B cell epitopes and T cell epitopes.
- B-cell epitopes are peptide sequences which are required for recognition by specific antibody producing B-cells.
- B cell epitopes refer to a specific region of the antigen that is recognized by an antibody.
- the portion of an antibody that binds to the epitope is called a paratope.
- An epitope may be a conformational epitope or a linear epitope, based on the structure and interaction with the paratope.
- a linear, or continuous, epitope is defined by the primary amino acid sequence of a particular region of a protein.
- the sequences that interact with the antibody are situated next to each other sequentially on the protein, and the epitope can usually be mimicked by a single peptide.
- Conformational epitopes are epitopes that are defined by the conformational structure of the native protein. These epitopes may be continuous or discontinuous, i.e. components of the epitope can be situated on disparate parts of the protein, which are brought close to each other in the folded native protein structure.
- T-cell epitopes are peptide sequences which, in association with proteins on APC, are required for recognition by specific T-cells.
- T cell epitopes are processed intracellularly and presented on the surface of APCs, where they are bound to MHC molecules including MHC class II and MHC class I.
- the peptide epitope may be any length that is reasonable for an epitope. In some embodiments the peptide epitope is 9-30 amino acids.
- the length is 9-22, 9-29, 9-28, 9-27, 9-26, 9-25, 9-24, 9-23, 9-21, 9-20, 9-19, 9-18, 10-22, 10-21, 10-20, 11-22, 22-21, 11-20, 12-22, 12-21, 12-20, 13-22, 13-21, 13-20, 14-19, 15-18, or 16-17 amino acids.
- the immunomodulatory therapeutic composition may include a recall antigen, also sometimes referred to as a memory antigen.
- a recall antigen is an antigen that has previously been encountered by an individual and for which there are pre-existent memory lymphocytes.
- the recall antigen may be an infectious disease antigen that the individual has likely encountered such as an influenza antigen. The recall antigen helps promote a more robust immune response.
- the therapeutic mRNA can be delivered alone or in combination with other cancer therapeutics such as checkpoint inhibitors to provide a significantly enhanced immune response against tumors.
- the checkpoint inhibitors can enhance the effects of the mRNA encoding activing oncogenic peptides by eliminating some of the obstacles to promoting an immune response, thus allowing the activated T cells to efficiently promote an immune response against the tumor.
- the mRNA may be delivered to the subject in the form of carrier such as a lipid nanoparticle (LNP).
- LNP lipid nanoparticle
- a number of LNPs are known in the art. For instance some LNPs such as those which have been used previously to deliver siRNA various in animal models as well as in humans have been observed to cause an undesirable inflammatory response associated with a transient IgM response, typically leading to a reduction in antigen production and a compromised immune response.
- lipid nanoparticle-mRNA immunomodulatory therapeutic compositions are provided herein that generate T cell responses sufficient for therapeutic methods rather than promoting transient IgM responses.
- the LNPs described herein are not liposomes.
- a liposome as used herein is a lipid based structure having a simple lipid bilayer shell with a nucleic acid payload in the core.
- An mRNA construct encoding an antigen(s) of interest typically comprises, in addition to the antigen-encoding sequences, other structural properties as described herein for mRNA constructs (e.g., modified nucleobases, 5′ cap, 5′ UTR, 3′ UTR, miR binding site(s), polyA tail, as described herein). Suitable mRNA construct components are as described herein.
- the cancer antigens can be personalized cancer antigens.
- Personalized immunomodulatory therapeutic compositions may include RNA encoding for one or more known cancer antigens specific for the tumor or cancer antigens specific for each subject, referred to as neoepitopes or subject specific epitopes or antigens.
- a “subject specific cancer antigen” is an antigen that has been identified as being expressed in a tumor of a particular patient. The subject specific cancer antigen may or may not be typically present in tumor samples generally.
- Neoepitopes Tumor associated antigens that are not expressed or rarely expressed in non-cancerous cells, or whose expression in non-cancerous cells is sufficiently reduced in comparison to that in cancerous cells and that induce an immune response induced upon vaccination, are referred to as neoepitopes.
- Neoepitopes like tumor associated antigens, are completely foreign to the body and thus would not produce an immune response against healthy tissue or be masked by the protective components of the immune system.
- personalized immunomodulatory therapeutic compositions based on neoepitopes are desirable because such vaccine formulations will maximize specificity against a patient's specific tumor.
- Mutation-derived neoepitopes can arise from point mutations, non-synonymous mutations leading to different amino acids in the protein; read-through mutations in which a stop codon is modified or deleted, leading to translation of a longer protein with a novel tumor-specific sequence at the C-terminus; splice site mutations that lead to the inclusion of an intron in the mature mRNA and thus a unique tumor-specific protein sequence; chromosomal rearrangements that give rise to a chimeric protein with tumor-specific sequences at the junction of 2 proteins (i.e., gene fusion); frameshift mutations or deletions that lead to a new open reading frame with a novel tumor-specific protein sequence; and translocations.
- the immunomodulatory therapeutic compositions include at least 1 cancer antigens including mutations selected from the group consisting of frame-shift mutations and recombinations or any of the other mutations described herein.
- Methods for generating personalized immunomodulatory therapeutic compositions generally involve identification of mutations, e.g., using deep nucleic acid or protein sequencing techniques, identification of neoepitopes, e.g., using application of validated peptide-MHC binding prediction algorithms or other analytical techniques to generate a set of candidate T cell epitopes that may bind to patient HLA alleles and are based on mutations present in tumors, optional demonstration of antigen-specific T cells against selected neoepitopes or demonstration that a candidate neoepitope is bound to HLA proteins on the tumor surface and development of the vaccine.
- the immunomodulatory therapeutic compositions of the invention may include multiple copies of a single neoepitope, multiple different neoepitopes based on a single type of mutation, i.e. point mutation, multiple different neoepitopes based on a variety of mutation types, neoepitopes and other antigens, such as tumor associated antigens or recall antigens.
- Examples of techniques for identifying mutations include but are not limited to dynamic allele-specific hybridization (DASH), microplate array diagonal gel electrophoresis (MADGE), pyrosequencing, oligonucleotide-specific ligation, the TaqMan system as well as various DNA “chip” technologies i.e. Affymetrix SNP chips, and methods based on the generation of small signal molecules by invasive cleavage followed by mass spectrometry or immobilized padlock probes and rolling-circle amplification.

Nucleic acid sequencing may be performed on whole tumor genomes, tumor exomes (protein-encoding DNA), tumor transcriptomes, or exosomes. Real-time single molecule sequencing-by-synthesis technologies rely on the detection of fluorescent nucleotides as they are incorporated into a nascent strand of DNA that is complementary to the template being sequenced. Other rapid high throughput sequencing methods also exist. Protein sequencing may be performed on tumor proteomes. Additionally, protein mass spectrometry may be used to identify or validate the presence of mutated peptides bound to MHC proteins on tumor cells.

- these neoepitopes bind to class I HLA proteins with a greater affinity than the wild-type peptide and/or are capable of activating anti-tumor CD8 T-cells. Identical mutations in any particular gene are rarely found across tumors.
- Proteins of MHC class I are present on the surface of almost all cells of the body, including most tumor cells.
- the proteins of MHC class I are loaded with antigens that usually originate from endogenous proteins or from pathogens present inside cells, and are then presented to cytotoxic T-lymphocytes (CTLs).
- CTLs cytotoxic T-lymphocytes
- T-Cell receptors are capable of recognizing and binding peptides complexed with the molecules of MHC class I.
- Each cytotoxic T-lymphocyte expresses a unique T-cell receptor which is capable of binding specific MHC/peptide complexes.
- T-cell epitopes i.e. peptide sequences
- MHC molecules of class I or class II in the form of a peptide-presenting complex
- T-cell receptors of T-lymphocytes examples include for instance: Lonza Epibase, SYFPEITHI (Rammensee et al., Immunogenetics, 50 (1999), 213-219) and HLA_BIND (Parker et al., J. Immunol., 152 (1994), 163-175).
- neoepitopes Once putative neoepitopes are selected, they can be further tested using in vitro and/or in vivo assays. Conventional in vitro lab assays, such as Elispot assays may be used with an isolate from each patient, to refine the list of neoepitopes selected based on the algorithm's predictions. Neoepitope vaccines, methods of use thereof and methods of preparing are all described in PCT/US2016/044918 which is incorporated herein by reference in its entirety.
- the tumor antigen is an endogenous tumor antigen, such as a tumor antigen that is released upon destruction of tumor cells in situ. It has been established in the art that natural mechanisms exist that results in cell death in vivo leading to release of intracellular components such that an immune response may be stimulated against the intracellular components. Such mechanisms are referred to herein as immunogenic cell death and include necroptosis and pyroptosis. Accordingly, in one embodiment, an immune potentiator mRNA construct of the disclosure is administered to a tumor-bearing subject under conditions in which endogenous immunogenic cell death is occurring such that one or more endogenous tumor antigens are released, to thereby enhance an immune response against the tumor antigens.
- the immune potentiator mRNA construct is administered to a tumor-bearing subject together with a second mRNA construct encoding an “executioner mRNA construct”, which stimulates immunogenic cell death of tumor cells in the subject.
- executioner mRNA constructs include those encoding MLKL, RIPK3, RIPK1, DIABLO, FADD, GSDMD, caspase-4, caspase-5, caspase-11, Pyrin, NLRP3 and ASC/PYCARD.
- Executioner mRNA constructs, and their use in combination with an immune potentiator mRNA construct are described in further detail in U.S. Application Ser. No. 62/412,933, the entire contents of which is expressly incorporated herein by reference.
- the activating oncogene mutation peptides selected for inclusion in the immunomodulatory therapeutic composition typically will be high affinity binding peptides.
- the activating oncogene mutation peptide binds an HLA protein with greater affinity than a wild-type peptide.

- the subject specific activating oncogene mutation peptides may be identified in an exosome of the subject.
- the activating oncogene mutation peptides are identified in an exosome of the subject, such peptides are said to be representative of exosome peptides of the subject.
- Exosomes are small microvesicles shed by cells, typically having a diameter of approximately 30-100 nm. Exosomes are classically formed from the inward invagination and pinching off of the late endosomal membrane, resulting in the formation of a multivesicular body (MVB) laden with small lipid bilayer vesicles, each of which contains a sample of the parent cell's cytoplasm. Fusion of the MVB with the cell membrane results in the release of these exosomes from the cell, and their delivery into the blood, urine, cerebrospinal fluid, or other bodily fluids. Exosomes can be recovered from any of these biological fluids for further analysis.
- MVB multivesicular body
- Nucleic acids within exosomes have a role as biomarkers for tumor antigens.
- An advantage of analyzing exosomes in order to identify subject specific cancer antigens, is that the method circumvents the need for biopsies. This can be particularly advantageous when the patient needs to have several rounds of therapy including identification of cancer antigens, and vaccination.
- a number of methods of isolating exosomes from a biological sample have been described in the art. For example, the following methods can be used: differential centrifugation, low speed centrifugation, anion exchange and/or gel permeation chromatography, sucrose density gradients or organelle electrophoresis, magnetic activated cell sorting (MACS), nanomembrane ultrafiltration concentration, Percoll gradient isolation and using microfluidic devices. Exemplary methods are described in US Patent Publication No. 2014/0212871 for instance.

- IFN Type I interferon
- host cell DNA for example derived from damaged or dying cells
- Type I IFN signaling pathway plays a role in the development of adaptive anti-tumor immunity.
- many pathogens and cancer cells have evolved mechanisms to reduce or inhibit Type I interferon responses.
- activation (including stimulation and/or enhancement) of the Type I IFN signaling pathway in a subject in need thereof by providing an immune potentiator mRNA of the disclosure to the subject, stimulates or enhances an immune response in the subject in a wide variety of clinical situations, including treatment of cancer and pathogenic infections, as well as in potentiating vaccine responses to provide protective immunity.
- Type I interferons are pro-inflammatory cytokines that are rapidly produced in multiple different cell types, typically upon viral infection, and known to have a wide variety of effects.
- the canonical consequences of type I IFN production in vivo is the activation of antimicrobial cellular programs and the development of innate and adaptive immune responses.
- Type I IFN induces a cell-intrinsic antimicrobial state in infected and neighboring cells that limits the spread of infectious agents, particularly viral pathogens.
- Type I IFN also modulates innate immune cell activation (e.g., maturation of dendritic cells) to promote antigen presentation and nature killer cell functions.
- Type I IFN also promotes the development of high-affinity antigen-specific T and B cell responses and immunological memory (Ivashkiv and Donlin (2014) Nat Rev Immunol 14(1):36-49).
- Type I IFN activates dendritic cells (DCs) and promotes their T cell stimulatory capacity through autocrine signaling (Montoya et al., (2002) Blood 99:3263-3271).
- Type I IFN exposure facilitates maturation of DCs via increasing the expression of chemokine receptors and adhesion molecules (e.g., to promote DC migration into draining lymph nodes), co-stimulatory molecules, and MHC class I and class II antigen presentation.
- DCs that mature following type I IFN exposure can effectively prime protective T cell responses (Wijesundara et al., (2014) Front Immunol 29(412) and references therein).
- Type I IFN can either promote or inhibit T cell activation, proliferation, differentiation and survival depending largely on the timing of type I IFN signaling relative to T cell receptor signaling (Crouse et al., (2015) Nat Rev Immunol 15:231-242).
- MHC-I expression is upregulated in response to type I IFN in multiple cell types (Lindahl et al., (1976), J Infect Dis 133(Suppl):A66-A68; Lindahl et al., (1976) Proc Natl Acad Sci USA 17:1284-1287) which is a requirement for optimal T cell stimulation, differentiation, expansion and cytolytic activity.
- Type I IFN can exert potent co-stimulatory effects on CD8 T cells, enhancing CD8 T cell proliferation and differentiation (Curtsinger et al., (2005) J Immunol 174:4465-4469; Kolumam et al., (2005) J Exp Med 202:637-650).
- type I IFN signaling has both positive and negative effects on B cell responses depending on the timing and context of exposure (Braun et al., (2002) Int Immunol 14(4):411-419; Lin et al, (1998) 187(1):79-87).
- the survival and maturation of immature B cells can be inhibited by type I IFN signaling.
- type I IFN exposure has been shown to promote B cell activation, antibody production and isotype switch following viral infection or following experimental immunization (Le Bon et al., (2006) J Immunol 176:4:2074-2078; Swanson et al., (2010) J Exp Med 207:1485-1500).

- ER endoplasmic reticulum
- STING functions as a signaling adaptor linking the cytosolic detection of DNA to the TBK1/IRF3/Type I IFN signaling axis.
- the signaling adaptor functions of STING are activated through the direct sensing of cyclic dinucleotides (CDNs).
- CDNs include cyclic di-GMP (guanosine 5′-monophosphate), cyclic di-AMP (adenosine 5′-monophosphate) and cyclic GMP-AMP (cGAMP).
- CDNs are now known to constitute a class of pathogen-associated molecular pattern molecules (PAMPs) that activate the TBK1/IRF3/type I IFN signaling axis via direct interaction with STING.

- Mutant STING proteins resulting from polymorphisms mapped to the human TMEM173 gene have been described exhibiting a gain-of function or constitutively active phenotype. When expressed in vitro, mutant STING alleles were shown to potently stimulate induction of type I IFN (Liu et al., (2014) N Engl J Med 371:507-518; Jeremiah et al., (2014) J Clin Invest 124:5516-5520; Dobbs et al., (2015) Cell Host Microbe 18(2):157-168; Tang & Wang, (2015) PLoS ONE 10(3):e0120090; Melki et al., (2017) J Allergy Clin Immunol In Press; Konig et al., (2017) Ann Rheum Dis 76(2):468-472; Burdette et al.

- the present disclosure provides mRNA (including mmRNA) encoding Interferon Regulatory Factors, such as IRF1, IRF3, IRF5, IRF7, IRF8, and IRF9 as immune potentiators.
- IRF1, IRF3, IRF5, IRF7, IRF8, and IRF9 Interferon Regulatory Factors
- the IRF transcription factor family is involved in the regulation of gene expression leading to the production of type I interferons (IFNs) during innate immune responses.
- IFNs type I interferons
- IFNs type I interferons
- DBDs N-terminal binding domains
- IRF1, IRF3, IRF5, and IRF7 have been specifically implicated as positive regulators of type I IFN gene transcription (Honda et al., (2006) Immunity 25(3):349-360).
- IRF1 was the first family member discovered to activate type I IFN gene promoters (Miyamoto et al., (1988) Cell 54:903-913). Although studies show that IRF1 participates in type I IFN gene expression, normal induction of type IFN was observed in virus-infected IRF1 ⁇ / ⁇ murine fibroblasts, suggesting dispensability (Matsuyama et al., (1993) Cell 75:83-97).
- IRF5 was also shown to be dispensable for type I IFN induction by viruses or TLR agonists (Takaoka et al., (2005) Nature 434:243-249).
- the disclosure provides mRNA encoding constitutively active forms of human IRF1, IRF3, IRF5, IRF7, IRF8, and IRF9 as immune potentiators.
- the disclosure provides mRNA encoding constitutively active forms of human IRF3 and/or IRF7.
- IRF-3 plays a critical role in the early induction of type I IFNs.
- the IRF3 transcription factor is constitutively expressed and shuttles between the nucleus and cytoplasm of cells in latent form, with a predominantly cytosolic localization prior to phosphorylation (Hiscott (2007) J Biol Chem 282(21):15325-15329; Kumar et al., (2000) Mol Cell Biol 20(11):4159-4168).
- IRF3 Upon phosphorylation of serine residues at the C-terminus by TBK-1 (TANK binding kinase 1; also known as T2K and NAK) and/or IKK ⁇ (inducible I ⁇ B kinase; also known as IKKi), IRF3 translocates from the cytoplasm into the nucleus (Fitzgerald et al., (2003) Nat Immuno 4(5):491-496; Sharma et al., (2003) Science 300:1148-1151; Hemmi et al., (2004) J Exp Med 199:1641-1650). The transcriptional activity of IRF3 is mediated by these phosphorylation and translocation events.
- TBK-1 TANK binding kinase 1
- IKK ⁇ inducible I ⁇ B kinase
- a model for IRF3 activation proposes that C-terminal phosphorylation induces a conformational change in IRF3 that promotes homo- and/or heterodimerization (e.g. with IRF7; see Honda et al., (2006) Immunity 25(3):346-360), nuclear localization, and association with the transcriptional co-activators CBP and/or p300 (Lin et al., (1999) Mol Cell Biol 19(4):2465-2474).
- IRF3 While inactive IRF3 constitutively shuttles into and out of the nucleus, phosphorylated IRF3 proteins remain associated with CBP and/or p300, are retained in the nucleus, and induce transcription of IFN and other genes (Kumar et al., (2000) Mol Cell Biol 20(11):4159-4168).
- IRF7 In contrast to IRF3, IRF7 exhibits a low expression level in most cells, but is strongly induced by type I IFN-mediated signaling, supporting the notion that IRF3 is primarily responsible for the early induction of IFN genes and that IRF7 is involved in the late induction phase (Sato et al., (2000) Immunity 13(4):539-548).
- Ligand-binding to the type I IFN receptor results in the activation of a heterotrimeric transcriptional activator, termed IFN-stimulated gene factor 3 (ISGF3), which consists of IRF9, STAT1, and STAT2, and is responsible for the induction of the IRF7 gene (Marie et al., (1998) EMBO J 17(22):6660-6669).
- IGF3 IFN-stimulated gene factor 3
- IRF7 can partition between cytoplasm and nucleus after serine phosphorylation of its C-terminal region, allowing its dimerization and nuclear translocation. IRF7 forms a homodimer or a heterodimer with IRF3, and each of these different dimers differentially acts on the type I IFN gene family members. IRF3 is more potent in activating the IFN- ⁇ gene than the IFN- ⁇ genes, whereas IRF7 efficiently activates both IFN- ⁇ and IFN- ⁇ genes (Marie et al., (1998) EMBO J 17(22):6660-6669).

- a miRNA binding site includes a sequence that has complementarity (e.g., partial or complete complementarity) with a miRNA seed sequence. In some embodiments, the miRNA binding site includes a sequence that has complete complementarity with a miRNA seed sequence. In some embodiments, a miRNA binding site includes a sequence that has complementarity (e.g., partial or complete complementarity) with an miRNA sequence. In some embodiments, the miRNA binding site includes a sequence that has complete complementarity with a miRNA sequence. In some embodiments, a miRNA binding site has complete complementarity with a miRNA sequence but for 1, 2, or 3 nucleotide substitutions, terminal additions, and/or truncations.
- the miRNA binding site is the same length as the corresponding miRNA. In other embodiments, the miRNA binding site is one, two, three, four, five, six, seven, eight, nine, ten, eleven or twelve nucleotide(s) shorter than the corresponding miRNA at the 5′ terminus, the 3′ terminus, or both. In still other embodiments, the microRNA binding site is two nucleotides shorter than the corresponding microRNA at the 5′ terminus, the 3′ terminus, or both. The miRNA binding sites that are shorter than the corresponding miRNAs are still capable of degrading the mRNA incorporating one or more of the miRNA binding sites or preventing the mRNA from translation.
- the miRNA binding site binds the corresponding mature miRNA that is part of an active RISC containing Dicer. In another embodiment, binding of the miRNA binding site to the corresponding miRNA in RISC degrades the mRNA containing the miRNA binding site or prevents the mRNA from being translated. In some embodiments, the miRNA binding site has sufficient complementarity to miRNA so that a RISC complex comprising the miRNA cleaves the polynucleotide comprising the miRNA binding site. In other embodiments, the miRNA binding site has imperfect complementarity so that a RISC complex comprising the miRNA induces instability in the polynucleotide comprising the miRNA binding site. In another embodiment, the miRNA binding site has imperfect complementarity so that a RISC complex comprising the miRNA represses transcription of the polynucleotide comprising the miRNA binding site.
- the miRNA binding site has one, two, three, four, five, six, seven, eight, nine, ten, eleven or twelve mismatch(es) from the corresponding miRNA.
- the miRNA binding site has at least about ten, at least about eleven, at least about twelve, at least about thirteen, at least about fourteen, at least about fifteen, at least about sixteen, at least about seventeen, at least about eighteen, at least about nineteen, at least about twenty, or at least about twenty-one contiguous nucleotides complementary to at least about ten, at least about eleven, at least about twelve, at least about thirteen, at least about fourteen, at least about fifteen, at least about sixteen, at least about seventeen, at least about eighteen, at least about nineteen, at least about twenty, or at least about twenty-one, respectively, contiguous nucleotides of the corresponding miRNA.
- the polynucleotide By engineering one or more miRNA binding sites into a polynucleotide of the disclosure, the polynucleotide can be targeted for degradation or reduced translation, provided the miRNA in question is available. This can reduce off-target effects upon delivery of the polynucleotide. For example, if a polynucleotide of the disclosure is not intended to be delivered to a tissue or cell but ends up is said tissue or cell, then a miRNA abundant in the tissue or cell can inhibit the expression of the gene of interest if one or multiple binding sites of the miRNA are engineered into the 5′UTR and/or 3′UTR of the polynucleotide.
- miRNA binding sites can be removed from polynucleotide sequences in which they naturally occur in order to increase protein expression in specific tissues.
- a binding site for a specific miRNA can be removed from a polynucleotide to improve protein expression in tissues or cells containing the miRNA.
- a polynucleotide of the disclosure can include at least one miRNA-binding site in the 5′UTR and/or 3′UTR in order to regulate cytotoxic or cytoprotective mRNA therapeutics to specific cells such as, but not limited to, normal and/or cancerous cells.
- a polynucleotide of the disclosure can include two, three, four, five, six, seven, eight, nine, ten, or more miRNA-binding sites in the 5′-UTR and/or 3′-UTR in order to regulate cytotoxic or cytoprotective mRNA therapeutics to specific cells such as, but not limited to, normal and/or cancerous cells.
- Regulation of expression in multiple tissues can be accomplished through introduction or removal of one or more miRNA binding sites, e.g., one or more distinct miRNA binding sites.
- the decision whether to remove or insert a miRNA binding site can be made based on miRNA expression patterns and/or their profilings in tissues and/or cells in development and/or disease. Identification of miRNAs, miRNA binding sites, and their expression patterns and role in biology have been reported (e.g., Bonauer et al., Curr Drug Targets 2010 11:943-949; Anand and Cheresh Curr Opin Hematol 2011 18:171-176; Contreras and Rao Leukemia 2012 26:404-413 (2011 Dec. 20.

- miRNAs are known to be differentially expressed in immune cells (also called hematopoietic cells), such as antigen presenting cells (APCs) (e.g., dendritic cells and macrophages), macrophages, monocytes, B lymphocytes, T lymphocytes, granulocytes, natural killer cells, etc.
- APCs antigen presenting cells
- Immune cell specific miRNAs are involved in immunogenicity, autoimmunity, the immune response to infection, inflammation, as well as unwanted immune response after gene therapy and tissue/organ transplantation. Immune cell specific miRNAs also regulate many aspects of development, proliferation, differentiation and apoptosis of hematopoietic cells (immune cells).
- miR-142 and miR-146 are exclusively expressed in immune cells, particularly abundant in myeloid dendritic cells. It has been demonstrated that the immune response to a polynucleotide can be shut-off by adding miR-142 binding sites to the 3′-UTR of the polynucleotide, enabling more stable gene transfer in tissues and cells. miR-142 efficiently degrades exogenous polynucleotides in antigen presenting cells and suppresses cytotoxic elimination of transduced cells (e.g., Annoni A et al., blood, 2009, 114, 5152-5161; Brown B D, et al., Nat med. 2006, 12(5), 585-591; Brown B D, et al., blood, 2007, 110(13): 4144-4152, each of which is incorporated herein by reference in its entirety).
- An antigen-mediated immune response can refer to an immune response triggered by foreign antigens, which, when entering an organism, are processed by the antigen presenting cells and displayed on the surface of the antigen presenting cells. T cells can recognize the presented antigen and induce a cytotoxic elimination of cells that express the antigen.
- Introducing a miR-142 binding site into the 5′UTR and/or 3′UTR of a polynucleotide of the disclosure can selectively repress gene expression in antigen presenting cells through miR-142 mediated degradation, limiting antigen presentation in antigen presenting cells (e.g., dendritic cells) and thereby preventing antigen-mediated immune response after the delivery of the polynucleotide.
- the polynucleotide is then stably expressed in target tissues or cells without triggering cytotoxic elimination.
- binding sites for miRNAs that are known to be expressed in immune cells can be engineered into a polynucleotide of the disclosure to suppress the expression of the polynucleotide in antigen presenting cells through miRNA mediated RNA degradation, subduing the antigen-mediated immune response. Expression of the polynucleotide is maintained in non-immune cells where the immune cell specific miRNAs are not expressed.

- The instant application contains a Sequence Listing which has been submitted in ASCII format via EFS-Web and is hereby incorporated by reference in its entirety. Said ASCII copy, created Nov. 18, 2020, is named MDN_015PCCN3DV_Sequence_Listing.txt and is 491042 bytes in size.
- The ability to modulate an immune response is beneficial in a variety of clinical situations, including the treatment of cancer and pathogenic infections, as well as in potentiating vaccine responses to provide protective immunity. A number of therapeutic tools exist for modulating the function of biological pathways and/or molecules that are involved in diseases such as cancer and pathogenic infections. These tools include, for example, small molecule inhibitors, cytokines and therapeutic antibodies. Some of these tools function through modulating immune responses in a subject, such as cytokines that modulate the activity of cells within the immune system or immune checkpoint inhibitor antibodies, such as anti-CTLA-4 or anti-PD-L1 that modulate the regulation of immune responses.
- Additionally, vaccines have long been used to stimulate an immune response against antigens of pathogens to thereby provide protective immunity against later exposure to the pathogens. More recently, vaccines have been developed using antigens found on tumor cells to thereby enhance anti-tumor immunoresponsiveness. In addition to the antigen(s) used in the vaccine, other agents may be included in a vaccine preparation, or used in combination with the vaccine preparation, to further boost the immune response to the vaccine. Such agents that enhance vaccine responsiveness are referred to in the art as adjuvants. Examples of commonly used vaccine adjuvants include aluminum gels and salts, monophosphoryl lipid A, MF59 oil-in-water emulsion, Freund's complete adjuvant, Freund's incomplete adjuvant, detergents and plant saponins. These adjuvants typically are used with protein or peptide based vaccines. Alternative types of vaccines, such as RNA based vaccines, are now being developed.
- There exists a need in the art for additional effective agents that enhance immune responses to an antigen of interest.
- Provided herein are immunomodulatory therapeutic compositions, including lipid-based compositions such as lipid nanoparticles, which include an RNA (e.g., messenger RNA (mRNA)) that can safely direct the body's cellular machinery to produce a cancer protein or fragment thereof of interest, e.g., an activating oncogene mutation peptide. In some embodiments, the RNA is a modified RNA. The immunomodulatory therapeutic compositions, including mRNA compositions and/or lipid nanoparticles comprising the same are useful to induce a balanced immune response against cancers, comprising both cellular and humoral immunity, without risking the possibility of insertional mutagenesis, for example.
- The immunomodulatory therapeutic compositions, including mRNA compositions and/or lipid nanoparticles of the disclosure may be utilized in various settings depending on the prevalence of the cancer or the degree or level of unmet medical need. The immunomodulatory therapeutic compositions, including mRNA compositions and lipid nanoparticles of the disclosure may be utilized to treat and/or prevent a cancer of various stages or degrees of metastasis. The immunomodulatory therapeutic compositions and lipid nanoparticles of the disclosure have superior properties in that they produce much larger antibody titers and produce responses earlier than alternative anti-cancer therapies including cancer vaccines. While not wishing to be bound by theory, it is believed that the provided compositions, such as mRNA polynucleotides, are better designed to produce the appropriate protein conformation upon translation as the RNA co-opt natural cellular machinery. Unlike traditional therapies and vaccines which are manufactured ex vivo and may trigger unwanted cellular responses, RNA of the provided compositions are presented to the cellular system in a more native fashion.
- In some aspects, the disclosure provides an immunomodulatory therapeutic composition, comprising: one or more mRNA each comprising an open reading frame encoding an activating oncogene mutation peptide, and optionally one or more mRNA each comprising an open reading frame encoding a polypeptide that enhances an immune response to the activating oncogene mutation peptide in a subject, wherein the immune response comprises a cellular or humoral immune response characterized by: (i) stimulating Type I interferon pathway signaling, (ii) stimulating NFkB pathway signaling, (iii) stimulating an inflammatory response, (iv) stimulating cytokine production, (v) stimulating dendritic cell development, activity or mobilization, and (vi) a combination of any of (i)-(v); and a pharmaceutically acceptable carrier.
- In some aspects, the disclosure provides an immunomodulatory therapeutic composition, including mRNA compositions and/or lipid nanoparticles comprising the same, that enhances an immune response by, for example, stimulating Type I interferon pathway signaling, stimulating NFkB pathway signaling, stimulating an inflammatory response, stimulating cytokine production or stimulating dendritic cell development, activity or mobilization. Enhancement of an immune response to an antigen of interest by an immune potentiator mRNA results in, for example, stimulation of cytokine production, stimulation of cellular immunity (T cell responses), such as antigen-specific CD8+ or CD4+ T cell responses and/or stimulation of humoral immunity (B cell responses), such as antigen-specific antibody responses.

The immune potentiator mRNAs of the disclosure enhance immune responses by, for example, activating Type I interferon pathway signaling such that antigen-specific responses to an antigen of interest (i.e., activating oncogene mutation peptide(s)) are stimulated.
- The immune potentiator mRNAs of the disclosure enhance immune responses to an exogenous antigen that is administered to the subject with the immune potentiator mRNA (e.g., an mRNA construct encoding activating oncogene mutation peptide(s) that is coformulated and coadministered with the immune potentiator mRNA or an mRNA construct encoding activating oncogene mutation peptide(s) that is formulated and administered separately from the immune potentiator mRNA). Administration of an immune potentiator mRNA enhances an immune response in a subject by stimulating, for example, cytokine production, T cells responses (e.g., antigen-specific CD8+ or CD4+ T cell responses) or B cell responses (e.g., antigen-specific antibody production) in the subject.
- In other aspects, the disclosure provides compositions, including mRNA compositions and lipid nanoparticles, comprising one or more mRNA constructs (e.g., one or more mmRNA constructs), wherein the one or more mRNA constructs encode an activating oncogene mutation peptide(s) and, in the same or a separate mRNA construct, encode a polypeptide that enhances an immune response to the antigen of interest. In some aspects, the disclosure provides nanoparticles, e.g., lipid nanoparticles, which include an immune potentiator mRNA that enhances an immune response, alone or in combination with mRNAs that encode activating oncogene mutation peptide(s). The disclosure also provides pharmaceutical compositions comprising any of the mRNAs as described herein or nanoparticles, e.g., lipid nanoparticles comprising any of the mRNAs as described herein.
- In other aspects, the disclosure provides methods for enhancing an immune response to an activating oncogene mutation peptide(s) by administering to a subject one or more mRNAs encoding activating oncogene mutation peptide(s) and a mRNA encoding a polypeptide that enhances an immune response to the peptide(s) of interest, or lipid nanoparticle thereof, or pharmaceutical composition thereof, such that an immune response to the activating oncogene mutation peptide(s) is enhanced in the subject. The methods of enhancing an immune response can be used, for example, to stimulate an immunogenic response to a tumor in a subject.
- The immune potentiators mRNAs of the disclosure are useful in combination with any type of antigen for which enhancement of an immune response is desired, including with mRNA sequences encoding at least one antigen of interest (on either the same or a separate mRNA construct) to enhance immune responses against the antigen of interest, such as a tumor antigen. Thus, the immune potentiator mRNAs of the disclosure enhance, for example, mRNA vaccine responses, thereby acting as genetic adjuvants.
- Activating Oncogene Mutation Peptides
- In one embodiment, the antigen(s) of interest is a tumor antigen. In one embodiment, the tumor antigen comprises a tumor neoepitope, e.g., mutant peptide from a tumor antigen. In one embodiment, the tumor antigen is a Ras antigen. A comprehensive survey of Ras mutations in cancer has been described in the art (Prior, I. A. et al. (2012) Cancer Res. 72:2457-2467). Accordingly, a Ras amino acid sequence comprising at least one mutation associated with cancer can be used as an antigen of interest. In one embodiment, the tumor antigen is a mutant KRAS antigen. Mutant KRAS antigens have been implicated in acquired resistance to certain therapeutic agents (see e.g., Misale, S. et al. (2012) Nature 486:532-536; Diaz, L. A. et al. (2012) Nature 486:537-540).
- Although attempts have been made to produce functional immunomodulatory therapeutic compositions, including mRNA compositions, the therapeutic efficacy of these RNA compositions has not yet been fully established. Quite surprisingly, the inventors have discovered a class of formulations for delivering mRNA immunomodulatory therapeutic compositions that results in significantly enhanced, and in many respects synergistic, immune responses including enhanced T cell responses. KRAS is the most frequently mutated oncogene in human cancer (˜15%). Such KRAS mutations are mostly conserved in a few “hotspots” and activate the oncogene.
- The immunomodulatory therapeutic compositions of the invention include activating oncogene mutation peptides, such as KRAS mutation peptides. Prior research has shown limited ability to raise T cells specific to the oncogenic mutation. Much of this research was done in the context of the most common HLA allele (A2, which occurs in −50% of Caucasians). More recent work has explored the generation of specific T cells against point mutations in the context of less common HLA alleles (A11, C8). These findings have significant implications for the treatment of cancer. Oncogenic mutations are common in many cancers. The ability to target these mutations and generate T cells that are sufficient to kill tumors has broad applicability to cancer therapy. It is quite surprising that delivery of antigens using mRNA would have such a significant advantage over the delivery of peptide vaccines. Thus the invention involves, in some aspects, the surprising finding that activating oncogenic mutation antigens delivered in vivo in the form of an mRNA significantly enhances the generation of T cell effector and memory responses.
- HLA class I molecules are highly polymorphic trans-membrane glycoproteins composed of two polypeptide chains (heavy chain and light chain). Human leucocyte antigen, the major histocompatibility complex in humans, is specific to each individual and has hereditary features. The class I heavy chains are encoded by three genes: HLA-A, HLA-B and HLA-C. HLA class I molecules are important for establishing an immune response by presenting endogenous antigens to T lymphocytes, which initiates a chain of immune reactions that lead to tumor cell elimination by cytotoxic T cells. Altered levels of production of HLA class I antigens is a widespread phenomenon in malignancies and is accompanied by significant inhibition of anti-tumor T cell function. It represents one of the main mechanisms used by cancer cells to evade immuno-surveillance. Down regulated levels of HLA class I antigens were detected in 90% of NSCLC tumors (n=65). A reduction or loss of HLA was detected in 76% of pancreatic tumor samples (n=19). The expression of HLA class I antigens in colon cancer was dramatically reduced or undetectable in 96% of tumor samples (n=25).
- Mounting evidence suggests that two general strategies are utilized by tumor cells to escape immune surveillance: immunoselection (poorly immunogenic tumor cell variants) and immunosubversion (subversion of the immune system). A correlation between changes in HLA class I antigens and the presence of
KRAS codon 12 mutations was demonstrated, which suggests a possible inductive effect ofKRAS codon 12 mutations on HLA class I antigen regulation in cancer progression. Many frequent cancer mutations are predicted to bind HLA Class I alleles with high-affinity (IC50<=50 nM)7 and may be suitable for prophylactic cancer vaccination. - The generation of cancer antigens that elicit a desired immune response (e.g. T-cell responses) against targeted polypeptide sequences in immunomodulatory therapeutic development remains a challenging task. The invention involves technology to overcome hurdles associated with such development. Through the use of the technology of the invention, it is possible to elicit a desired immune response by selecting appropriate activating oncogene mutation peptides and formulating the mRNA encoding peptides for effective delivery in vivo.
- The immunomodulatory therapeutic compositions provide unique therapeutic alternatives to peptide based or DNA vaccines. When the mRNA containing immunomodulatory therapeutic composition is delivered to a cell, the mRNA will be translated into a polypeptide by the intracellular machinery which can then process the polypeptide into sensitive fragments capable of being presented on MDC and stimulating an immune response against the tumor.
- The immunomodulatory therapeutic compositions described herein include at least one ribonucleic acid (RNA) polynucleotide having an open reading frame encoding at least one cancer antigenic polypeptide or an immunogenic fragment thereof (e.g., an immunogenic fragment capable of inducing an immune response to cancer). The antigenic peptide includes an activating oncogenic mutation. In some preferred embodiments the composition is multiple epitopes of a mixture of activating oncogenic mutations. Many activating oncogenic mutations are known in the art.
- When oncogenes are activated they can inhibit programmed cell death and/or cause abnormal cellular proliferation. Such oncogene activation can lead to cancer. The KRAS gene (Ki-ras2 Kirsten rat sarcoma viral oncogene homolog) is an oncogene that encodes a small GTPase transductor protein. KRAS relays external signals to the cell nucleus and contributes to regulation of cell division. Activating mutations in the KRAS gene impair the ability of the KRAS protein to switch between active and inactive states. KRAS activation leads to cell transformation and increased resistance to chemotherapy and biological therapies targeting epidermal growth factor receptors. (Jancik, Sylwia et al. Clinical Relevance of KRAS in Human Cancers, Journal of Biomedicine and Biotechnology, Volume 2010 Article ID 150960 (2010)). Human KRAS amino acid sequence is provided below (UniProtKB P01116). KRAS mutations are common in many cancers, and G12 is the site of most common KRAS mutations.

For instance, 29% of Cutaneous Melanoma involves a RAS mutation, of which 94% are of N-RAS origin. This represents about 2,500 new US cases/year of the most aggressive form of melanoma accounting for the majority of melanoma deaths. (Channing Der, Are All RAS Proteins Created Equal in Cancer?, Sep. 22, 2014, cancer.gov). There are 30,280 news cases of multiple myeloma annually, of which 26% are NRAS*. This represents ˜6,100 new NRAS* cases per year. Thus, the N-Ras vaccines described herein are useful in some embodiments in the treatment of melanoma and multiple myeloma as well as other malignancies that harbor NRAS mutations.
- Accordingly, in some aspects, the present invention provides mRNA encoding peptide sequences resulting from certain activating mutations in one or more oncogenes, not limited to missense SNVs and often resulting in alternative splicing, for use as targets for therapeutic vaccination. In some embodiments, the activating oncogene mutation is a KRAS mutation. In some embodiments, the KRAS mutation is a G12 mutation. In some embodiments, the G12 KRAS mutation is selected from a G12D, G12V, G12S, G12C, G12A, and a G12R KRAS mutation, e.g., the G12 KRAS mutation is selected from a G12D, G12V, and a G12S KRAS mutation. In some embodiments, the G12 KRAS mutation is selected from a G12D, G12V, and a G12C KRAS mutation. In other embodiments, the KRAS mutation is a G13 mutation, e.g., the G13 KRAS mutation is a G13D KRAS mutation. In some embodiments, the activating oncogene mutation is a H-RAS or N-RAS mutation.
- In one embodiment, one or more mRNAs encode a mutant KRAS peptide(s) comprising an amino acid sequence having one or more mutations selected from G12D, G12V, G13D and G12C, and combinations thereof. Non-limiting examples of mutant KRAS antigens include those comprising one or more of the amino acid sequences shown in SEQ ID NOs: 36-41 and 72, 125.
- CD8+ T cells specific for the G12D or G12V mutations can be restricted by HLA-A*02:01, A*03:01; -A*11:01, -B*35:01, -Cw*08:02, and potentially others. Accordingly, in some embodiments, a KRAS mutation is selected for inclusion in an immunomodulatory therapeutic composition for a subject having T cells that are restricted by HLA-A*02:01, A*03:01; -A*11:01, -B*35:01, or -Cw*08:02. In some embodiments, the subject has T cells that are HLA-A*02:01 restricted.
- In one embodiment, the mutant KRAS antigen is one or more mutant KRAS 15-mer peptides comprising a mutation selected from G12D, G12V, G13D and G12C, non-limiting examples of which are shown in SEQ ID NO: 36-38 and 125.
- In another embodiment, the mutant KRAS antigen is one or more mutant KRAS 25-mer peptides comprising a mutation selected from G12D, G12V, G13D and G12C, non-limiting examples of which are shown in SEQ ID NO: 39-41 and 72.
- In another embodiment, the mutant KRAS antigen is one or more
mutant KRAS 3×15 mer peptides (3 copies of the 15-mer peptide) comprising a mutation selected from G12D, G12V, G13D and G12C, non-limiting examples of which are shown in SEQ ID NO: 42-44 and 183. - In another embodiment, the mutant KRAS antigen is one or more
mutant KRAS 3×25mer peptides (three copies of the 25-mer peptide) comprising a mutation selected from G12D, G12V, G13D and G12C, non-limiting examples of which are shown in SEQ ID NO: 45-47 and 73. - In another embodiment, the mutant KRAS antigen is a 100-mer concatemer peptide of the 25-mer peptides containing the G12D, G12V, G13D and G12C mutations (i.e., a 100-mer concatemer of SEQ ID NOs: 39, 40, 41 and 72). Accordingly, in one embodiment, the mutant KRAS antigen comprises an mRNA construct encoding SEQ ID NOs: 39, 40, 41 and 72. Non-limiting examples of nucleotide sequences encoding a concatemer of peptides containing G12D, G12V, G13D and G12C mutations include SEQ ID NO: 138, SEQ ID NO: 167 and SEQ ID NO: 169. Further description of mutant KRAS antigens, amino acid sequences thereof, and mRNA sequences encoding therefor, are disclosed in U.S. Application Ser. No. 62/453,465, the entire contents of which is expressly incorporated herein by reference.
- Some embodiments of the present disclosure provide immunomodulatory therapeutic compositions that include an mRNA having an open reading frame encoding a concatemer of two or more activating oncogene mutation peptides. In some embodiments, at least two of the peptide epitopes are separated from one another by a single Glycine. In some embodiments, the concatemer comprises 3-10 activating oncogene mutation peptides. In some such embodiments, all of the peptide epitopes are separated from one another by a single Glycine. In other embodiments, at least two of the peptide epitopes are linked directly to one another without a linker.
- In one embodiment, a tumor antigen is encoded by an mRNA construct that also comprises an immune potentiator (i.e., also encodes a polypeptide that enhances an immune response against the tumor antigen). Non-limiting examples of such constructs include the KRAS-STING constructs encoding one of the amino acid sequences shown in SEQ ID NOs: 48-71. Non-limiting examples of nucleotide sequences encoding the KRAS-STING constructs are shown in SEQ ID NOs: 160-163 and 221-224.
- The disclosure provides an immunomodulatory therapeutic composition, comprising: an mRNA having an open reading frame encoding a concatemer of two or more activating oncogene mutation peptides, wherein the concatemer comprises KRAS activating oncogene mutation peptides G12D, G12V, G12C, and G13D; and one or more mRNA each having an open reading frame encoding a polypeptide that enhances an immune response to the KRAS activating oncogene mutation peptides in a subject, such as a STING immune potentiator mRNA. Such an immunomodulatory composition targets somatic point mutations of KRAS, which constitute not only exquisitely specific tumor neoantigens but also significant oncogenic driver mutations in various malignancies. Unlike many neoantigens, which are largely passenger mutations, maintenance of KRAS mutant expression is important to cancer cells' survival as it helps drive aberrant cell proliferation and is likely to be a truncal event (an early event and therefore present in many tumor cells).
- In order to model KRAS mutant antigens in preclinical studies described herein examining the immune potentiating capacity of STING, two model antigens were selected: (1) HPV E6 and E7 and (2) the ADR concatemer of three point mutations from three genes found in the murine cell line MC38. These antigens are appropriate models of the KRAS mutant antigens for a number of reasons. For example, HPV E6 and E7 are viral oncogenic proteins whose expression is vital for the transformed phenotype, like mutant KRAS. Accordingly, HPV E6 and E7 are suitable model antigens because, similar to mutant KRAS, they are oncogenic drivers. The three ADR mutant epitopes, in contrast, are stereotypical neoantigens in that they are most likely passenger mutations. However, ADR more effectively models other properties of KRAS antigens encoded by our vaccine in that: (1) each antigen contains a single missense mutation relative to its wild-type counterpart which is likely to be more challenging to recognize as “non-self” by the immune system than a viral antigen and (2) they are concatemerized.
- The immunomodulatory therapeutic compositions of the disclosure may include one or more cancer antigens. In some embodiments the immunomodulatory therapeutic composition is composed of 2 or more, 3 or more, 4 or more, 5 or more 6 or more 7 or more, 8 or more, 9 or more antigens, e.g., activating oncogene mutation peptides. In other embodiments the immunomodulatory therapeutic composition is composed of 1000 or less, 900 or less, 500 or less, 100 or less, 75 or less, 50 or less, 40 or less, 30 or less, 20 or less or 100 or less cancer antigens, e.g., activating oncogene mutation peptides. In yet other embodiments the immunomodulatory therapeutic composition has 3-10, 3-100, 5-100, 10-100, 15-100, 20-100, 25-100, 30-100, 35-100, 40-100, 45-100, 50-100, 55-100, 60-100, 65-100, 70-100, 75-100, 80-100, 90-100, 5-50, 10-50, 15-50, 20-50, 25-50, 30-50, 35-50, 40-50, 45-50, 100-150, 100-200, 100-300, 100-400, 100-500, 50-500, 50-800, 50-1,000, or 100-1,000 cancer antigens, e.g., activating oncogene mutation peptides.
- An epitope, also known as an antigenic determinant, as used herein is a portion of an antigen that is recognized by the immune system in the appropriate context, specifically by antibodies, B cells, or T cells. Epitopes include B cell epitopes and T cell epitopes. B-cell epitopes are peptide sequences which are required for recognition by specific antibody producing B-cells. B cell epitopes refer to a specific region of the antigen that is recognized by an antibody. The portion of an antibody that binds to the epitope is called a paratope. An epitope may be a conformational epitope or a linear epitope, based on the structure and interaction with the paratope. A linear, or continuous, epitope is defined by the primary amino acid sequence of a particular region of a protein. The sequences that interact with the antibody are situated next to each other sequentially on the protein, and the epitope can usually be mimicked by a single peptide. Conformational epitopes are epitopes that are defined by the conformational structure of the native protein. These epitopes may be continuous or discontinuous, i.e. components of the epitope can be situated on disparate parts of the protein, which are brought close to each other in the folded native protein structure.
- T-cell epitopes are peptide sequences which, in association with proteins on APC, are required for recognition by specific T-cells. T cell epitopes are processed intracellularly and presented on the surface of APCs, where they are bound to MHC molecules including MHC class II and MHC class I. The peptide epitope may be any length that is reasonable for an epitope. In some embodiments the peptide epitope is 9-30 amino acids. In other embodiments the length is 9-22, 9-29, 9-28, 9-27, 9-26, 9-25, 9-24, 9-23, 9-21, 9-20, 9-19, 9-18, 10-22, 10-21, 10-20, 11-22, 22-21, 11-20, 12-22, 12-21, 12-20, 13-22, 13-21, 13-20, 14-19, 15-18, or 16-17 amino acids.
- In some embodiments the immunomodulatory therapeutic composition may include a recall antigen, also sometimes referred to as a memory antigen. A recall antigen is an antigen that has previously been encountered by an individual and for which there are pre-existent memory lymphocytes. In some embodiments the recall antigen may be an infectious disease antigen that the individual has likely encountered such as an influenza antigen. The recall antigen helps promote a more robust immune response.
- The therapeutic mRNA can be delivered alone or in combination with other cancer therapeutics such as checkpoint inhibitors to provide a significantly enhanced immune response against tumors. The checkpoint inhibitors can enhance the effects of the mRNA encoding activing oncogenic peptides by eliminating some of the obstacles to promoting an immune response, thus allowing the activated T cells to efficiently promote an immune response against the tumor.
- The mRNA may be delivered to the subject in the form of carrier such as a lipid nanoparticle (LNP). A number of LNPs are known in the art. For instance some LNPs such as those which have been used previously to deliver siRNA various in animal models as well as in humans have been observed to cause an undesirable inflammatory response associated with a transient IgM response, typically leading to a reduction in antigen production and a compromised immune response. In contrast to the findings observed with siRNA, lipid nanoparticle-mRNA immunomodulatory therapeutic compositions are provided herein that generate T cell responses sufficient for therapeutic methods rather than promoting transient IgM responses. The LNPs described herein are not liposomes. A liposome as used herein is a lipid based structure having a simple lipid bilayer shell with a nucleic acid payload in the core.
- An mRNA construct encoding an antigen(s) of interest typically comprises, in addition to the antigen-encoding sequences, other structural properties as described herein for mRNA constructs (e.g., modified nucleobases, 5′ cap, 5′ UTR, 3′ UTR, miR binding site(s), polyA tail, as described herein). Suitable mRNA construct components are as described herein.
- Personalized Cancer Antigens-Neoepitopes
- The cancer antigens can be personalized cancer antigens. Personalized immunomodulatory therapeutic compositions, for instance, may include RNA encoding for one or more known cancer antigens specific for the tumor or cancer antigens specific for each subject, referred to as neoepitopes or subject specific epitopes or antigens. A “subject specific cancer antigen” is an antigen that has been identified as being expressed in a tumor of a particular patient. The subject specific cancer antigen may or may not be typically present in tumor samples generally. Tumor associated antigens that are not expressed or rarely expressed in non-cancerous cells, or whose expression in non-cancerous cells is sufficiently reduced in comparison to that in cancerous cells and that induce an immune response induced upon vaccination, are referred to as neoepitopes. Neoepitopes, like tumor associated antigens, are completely foreign to the body and thus would not produce an immune response against healthy tissue or be masked by the protective components of the immune system. In some embodiments personalized immunomodulatory therapeutic compositions based on neoepitopes are desirable because such vaccine formulations will maximize specificity against a patient's specific tumor. Mutation-derived neoepitopes can arise from point mutations, non-synonymous mutations leading to different amino acids in the protein; read-through mutations in which a stop codon is modified or deleted, leading to translation of a longer protein with a novel tumor-specific sequence at the C-terminus; splice site mutations that lead to the inclusion of an intron in the mature mRNA and thus a unique tumor-specific protein sequence; chromosomal rearrangements that give rise to a chimeric protein with tumor-specific sequences at the junction of 2 proteins (i.e., gene fusion); frameshift mutations or deletions that lead to a new open reading frame with a novel tumor-specific protein sequence; and translocations. Thus, in some embodiments the immunomodulatory therapeutic compositions include at least 1 cancer antigens including mutations selected from the group consisting of frame-shift mutations and recombinations or any of the other mutations described herein.
- Methods for generating personalized immunomodulatory therapeutic compositions generally involve identification of mutations, e.g., using deep nucleic acid or protein sequencing techniques, identification of neoepitopes, e.g., using application of validated peptide-MHC binding prediction algorithms or other analytical techniques to generate a set of candidate T cell epitopes that may bind to patient HLA alleles and are based on mutations present in tumors, optional demonstration of antigen-specific T cells against selected neoepitopes or demonstration that a candidate neoepitope is bound to HLA proteins on the tumor surface and development of the vaccine. The immunomodulatory therapeutic compositions of the invention may include multiple copies of a single neoepitope, multiple different neoepitopes based on a single type of mutation, i.e. point mutation, multiple different neoepitopes based on a variety of mutation types, neoepitopes and other antigens, such as tumor associated antigens or recall antigens.
- Examples of techniques for identifying mutations include but are not limited to dynamic allele-specific hybridization (DASH), microplate array diagonal gel electrophoresis (MADGE), pyrosequencing, oligonucleotide-specific ligation, the TaqMan system as well as various DNA “chip” technologies i.e. Affymetrix SNP chips, and methods based on the generation of small signal molecules by invasive cleavage followed by mass spectrometry or immobilized padlock probes and rolling-circle amplification.
- The deep nucleic acid or protein sequencing techniques are known in the art. Any type of sequence analysis method can be used. Nucleic acid sequencing may be performed on whole tumor genomes, tumor exomes (protein-encoding DNA), tumor transcriptomes, or exosomes. Real-time single molecule sequencing-by-synthesis technologies rely on the detection of fluorescent nucleotides as they are incorporated into a nascent strand of DNA that is complementary to the template being sequenced. Other rapid high throughput sequencing methods also exist. Protein sequencing may be performed on tumor proteomes. Additionally, protein mass spectrometry may be used to identify or validate the presence of mutated peptides bound to MHC proteins on tumor cells. Peptides can be acid-eluted from tumor cells or from HLA molecules that are immunoprecipitated from tumor cells, and then identified using mass spectrometry. The results of the sequencing may be compared with known control sets or with sequencing analysis performed on normal tissue of the patient.
- Accordingly, the present invention relates to methods for identifying and/or detecting neoepitopes of an antigen, such as T-cell epitopes. Specifically, the invention provides methods of identifying and/or detecting tumor specific neoepitopes that are useful in inducing a tumor specific immune response in a subject. Optionally, these neoepitopes bind to class I HLA proteins with a greater affinity than the wild-type peptide and/or are capable of activating anti-tumor CD8 T-cells. Identical mutations in any particular gene are rarely found across tumors.
- Proteins of MHC class I are present on the surface of almost all cells of the body, including most tumor cells. The proteins of MHC class I are loaded with antigens that usually originate from endogenous proteins or from pathogens present inside cells, and are then presented to cytotoxic T-lymphocytes (CTLs). T-Cell receptors are capable of recognizing and binding peptides complexed with the molecules of MHC class I. Each cytotoxic T-lymphocyte expresses a unique T-cell receptor which is capable of binding specific MHC/peptide complexes.
- Using computer algorithms, it is possible to predict potential neoepitopes such as T-cell epitopes, i.e. peptide sequences, which are bound by the MHC molecules of class I or class II in the form of a peptide-presenting complex and then, in this form, recognized by the T-cell receptors of T-lymphocytes. Examples of programs useful for identifying peptides which will bind to MHC include for instance: Lonza Epibase, SYFPEITHI (Rammensee et al., Immunogenetics, 50 (1999), 213-219) and HLA_BIND (Parker et al., J. Immunol., 152 (1994), 163-175).
- Once putative neoepitopes are selected, they can be further tested using in vitro and/or in vivo assays. Conventional in vitro lab assays, such as Elispot assays may be used with an isolate from each patient, to refine the list of neoepitopes selected based on the algorithm's predictions. Neoepitope vaccines, methods of use thereof and methods of preparing are all described in PCT/US2016/044918 which is incorporated herein by reference in its entirety.
- Endogeous Tumor Antigens
- In another embodiment, the tumor antigen is an endogenous tumor antigen, such as a tumor antigen that is released upon destruction of tumor cells in situ. It has been established in the art that natural mechanisms exist that results in cell death in vivo leading to release of intracellular components such that an immune response may be stimulated against the intracellular components. Such mechanisms are referred to herein as immunogenic cell death and include necroptosis and pyroptosis. Accordingly, in one embodiment, an immune potentiator mRNA construct of the disclosure is administered to a tumor-bearing subject under conditions in which endogenous immunogenic cell death is occurring such that one or more endogenous tumor antigens are released, to thereby enhance an immune response against the tumor antigens. In one embodiment, the immune potentiator mRNA construct is administered to a tumor-bearing subject together with a second mRNA construct encoding an “executioner mRNA construct”, which stimulates immunogenic cell death of tumor cells in the subject. Examples of executioner mRNA constructs include those encoding MLKL, RIPK3, RIPK1, DIABLO, FADD, GSDMD, caspase-4, caspase-5, caspase-11, Pyrin, NLRP3 and ASC/PYCARD. Executioner mRNA constructs, and their use in combination with an immune potentiator mRNA construct, are described in further detail in U.S. Application Ser. No. 62/412,933, the entire contents of which is expressly incorporated herein by reference.
- Characteristics of Cancer Antigens
- The activating oncogene mutation peptides selected for inclusion in the immunomodulatory therapeutic composition typically will be high affinity binding peptides. In some aspect the activating oncogene mutation peptide binds an HLA protein with greater affinity than a wild-type peptide. The activating oncogene mutation peptides has an IC50 of at least less than 5000 nM, at least less than 500 nM, at least less than 250 nM, at least less than 200 nM, at least less than 150 nM, at least less than 100 nM, at least less than 50 nM or less in some embodiments. Typically, peptides with predicted IC50<50 nM, are generally considered medium to high affinity binding peptides and will be selected for testing their affinity empirically using biochemical assays of HLA-binding.
- In some embodiments, subject specific activating oncogene mutation peptides may be identified in a sample of a patient. For instance, the sample may be a tissue sample or a tumor sample. For instance, a sample of one or more tumor cells may be examined for the presence of subject specific activating oncogene mutations. The tumor sample may be examined using whole genome, exome or transcriptome analysis in order to identify the subject specific activating oncogene mutations.
- Alternatively the subject specific activating oncogene mutation peptides may be identified in an exosome of the subject. When the activating oncogene mutation peptides are identified in an exosome of the subject, such peptides are said to be representative of exosome peptides of the subject.
- Exosomes are small microvesicles shed by cells, typically having a diameter of approximately 30-100 nm. Exosomes are classically formed from the inward invagination and pinching off of the late endosomal membrane, resulting in the formation of a multivesicular body (MVB) laden with small lipid bilayer vesicles, each of which contains a sample of the parent cell's cytoplasm. Fusion of the MVB with the cell membrane results in the release of these exosomes from the cell, and their delivery into the blood, urine, cerebrospinal fluid, or other bodily fluids. Exosomes can be recovered from any of these biological fluids for further analysis.
- Nucleic acids within exosomes have a role as biomarkers for tumor antigens. An advantage of analyzing exosomes in order to identify subject specific cancer antigens, is that the method circumvents the need for biopsies. This can be particularly advantageous when the patient needs to have several rounds of therapy including identification of cancer antigens, and vaccination.

- Immune Potentiator mRNAs
- One aspect of the disclosure pertains to mRNAs that encode a polypeptide that stimulates or enhances an immune response against one or more antigens of interest (activating oncogene mutation peptide(s)). Such mRNAs that enhance immune responses to an antigen(s) of interest are referred to herein as immune potentiator mRNA constructs or immune potentiator mRNAs, including chemically modified mRNAs (mmRNAs). In some aspects, the disclosure provides an mRNA encoding a polypeptide that stimulates or enhances an immune response in a subject in need thereof (e.g., potentiates an immune response in the subject) by, for example, inducing adaptive immunity (e.g., by stimulating Type I interferon production), stimulating an inflammatory response, stimulating NFkB signaling and/or stimulating dendritic cell (DC) development, activity or mobilization in the subject. In some aspects, administration of an immune potentiator mRNA to a subject in need thereof enhances cellular immunity (e.g., T cell-mediated immunity), humoral immunity (e.g., B cell-mediated immunity) or both cellular and humoral immunity in the subject. In some aspects, administration of an immune potentiator mRNA stimulates cytokine production (e.g., inflammatory cytokine production), stimulates antigen-specific CD8+ effector cell responses, stimulates antigen-specific CD4+ helper cell responses, increases the effector memory CD62Llo T cell population, stimulates B cell activity or stimulates antigen-specific antibody production, including combinations of the foregoing responses.
- In some aspects, administration of an immune potentiator mRNA stimulates cytokine production (e.g., inflammatory cytokine production) and stimulates antigen-specific CD8+ effector cell responses. In some aspects, administration of an immune potentiator mRNA stimulates cytokine production (e.g., inflammatory cytokine production), and stimulates antigen-specific CD4+ helper cell responses. In some aspects, administration of an immune potentiator mRNA stimulates cytokine production (e.g., inflammatory cytokine production), and increases the effector memory CD62Llo T cell population. In some aspects, administration of an immune potentiator mRNA stimulates cytokine production (e.g., inflammatory cytokine production), and stimulates B cell activity or stimulates antigen-specific antibody production.
- Immune Potentiators mRNAs that Stimulate Type I Interferon
- In some aspects, the disclosure provides an immune potentiator mRNA encoding a polypeptide that stimulates or enhances an immune response against an antigen of interest by simulating or enhacing Type I interferon pathway signaling, thereby stimulating or enhancing Type I interferon (IFN) production. It has been established that successful induction of anti-tumor or anti-microbial adaptive immunity requires Type I IFN signaling (see e.g., Fuertes, M. B. et al. (2013) Trends Immunol. 34:67-73). The production of Type I IFNs (including IFN-α, IFN-β, IFN-ε, IFN-κ and IFN-ω) plays a role in clearance of microbial infections, such as viral infections. It has also been appreciated that host cell DNA (for example derived from damaged or dying cells) is capable of inducing Type I interferon production and that the Type I IFN signaling pathway plays a role in the development of adaptive anti-tumor immunity. However, many pathogens and cancer cells have evolved mechanisms to reduce or inhibit Type I interferon responses. Thus, activation (including stimulation and/or enhancement) of the Type I IFN signaling pathway in a subject in need thereof, by providing an immune potentiator mRNA of the disclosure to the subject, stimulates or enhances an immune response in the subject in a wide variety of clinical situations, including treatment of cancer and pathogenic infections, as well as in potentiating vaccine responses to provide protective immunity.
- Type I interferons (IFNs) are pro-inflammatory cytokines that are rapidly produced in multiple different cell types, typically upon viral infection, and known to have a wide variety of effects. The canonical consequences of type I IFN production in vivo is the activation of antimicrobial cellular programs and the development of innate and adaptive immune responses. Type I IFN induces a cell-intrinsic antimicrobial state in infected and neighboring cells that limits the spread of infectious agents, particularly viral pathogens. Type I IFN also modulates innate immune cell activation (e.g., maturation of dendritic cells) to promote antigen presentation and nature killer cell functions. Type I IFN also promotes the development of high-affinity antigen-specific T and B cell responses and immunological memory (Ivashkiv and Donlin (2014) Nat Rev Immunol 14(1):36-49).
- Type I IFN activates dendritic cells (DCs) and promotes their T cell stimulatory capacity through autocrine signaling (Montoya et al., (2002) Blood 99:3263-3271). Type I IFN exposure facilitates maturation of DCs via increasing the expression of chemokine receptors and adhesion molecules (e.g., to promote DC migration into draining lymph nodes), co-stimulatory molecules, and MHC class I and class II antigen presentation. DCs that mature following type I IFN exposure can effectively prime protective T cell responses (Wijesundara et al., (2014) Front Immunol 29(412) and references therein).
- Type I IFN can either promote or inhibit T cell activation, proliferation, differentiation and survival depending largely on the timing of type I IFN signaling relative to T cell receptor signaling (Crouse et al., (2015) Nat Rev Immunol 15:231-242). Early studies revealed that MHC-I expression is upregulated in response to type I IFN in multiple cell types (Lindahl et al., (1976), J Infect Dis 133(Suppl):A66-A68; Lindahl et al., (1976) Proc Natl Acad Sci USA 17:1284-1287) which is a requirement for optimal T cell stimulation, differentiation, expansion and cytolytic activity. Type I IFN can exert potent co-stimulatory effects on CD8 T cells, enhancing CD8 T cell proliferation and differentiation (Curtsinger et al., (2005) J Immunol 174:4465-4469; Kolumam et al., (2005) J Exp Med 202:637-650).
- Similar to effects on T cells, type I IFN signaling has both positive and negative effects on B cell responses depending on the timing and context of exposure (Braun et al., (2002) Int Immunol 14(4):411-419; Lin et al, (1998) 187(1):79-87). The survival and maturation of immature B cells can be inhibited by type I IFN signaling. In contrast to immature B cells, type I IFN exposure has been shown to promote B cell activation, antibody production and isotype switch following viral infection or following experimental immunization (Le Bon et al., (2006) J Immunol 176:4:2074-2078; Swanson et al., (2010) J Exp Med 207:1485-1500).
- A number of components involved in Type I IFN pathway signaling have been established, including STING, Interferon Regulatory Factors, such as IRF1, IRF3, IRF5, IRF7, IRF8, and IRF9, TBK1, IKKi, MyD88 and TRAM. Additional components involved in Type I IFN pathway signaling include TRAF3, TRAF6, IRAK-1, IRAK-4, TRIF, IPS-1, TLR-3, TLR-4, TLR-7, TLR-8, TLR-9, RIG-1, DAI and IFI16.
- Accordingly, in one embodiment, an immune potentiator mRNA encodes any of the foregoing components involved in Type I IFN pathway signaling.
- The present disclosure encompasses mRNA (including mmRNA) encoding STING, including constitutively active forms of STING, as immune potentiators. STING (STimulator of INterferon Genes; also known as transmembrane protein 173 (TMEM173), mediator of IRF3 activation (MITA), methionine-proline-tyrosine-serine (MPYS), and ER IFN stimulator (ERIS)) is a 379 amino acid, endoplasmic reticulum (ER) resident transmembrane protein that functions as a signaling molecule controlling the transcription of immune response genes, including type I IFNs and pro-inflammatory cytokines (Ishikawa & Barber, (2008) Nature 455:647-678; Ishikawa et al., (2009) Nature 461:788-792; Barber (2010) Nat Rev Immunol 15(12):760-770).
- STING functions as a signaling adaptor linking the cytosolic detection of DNA to the TBK1/IRF3/Type I IFN signaling axis. The signaling adaptor functions of STING are activated through the direct sensing of cyclic dinucleotides (CDNs). Examples of CDNs include cyclic di-GMP (
guanosine 5′-monophosphate), cyclic di-AMP (adenosine 5′-monophosphate) and cyclic GMP-AMP (cGAMP). Initially characterized as ubiquitous bacterial secondary messengers, CDNs are now known to constitute a class of pathogen-associated molecular pattern molecules (PAMPs) that activate the TBK1/IRF3/type I IFN signaling axis via direct interaction with STING. STING is capable of sensing aberrant DNA species and/or CDNs in the cytosol of the cell, including CDNs derived from bacteria, and/or from the host protein cyclic GMP-AMP synthase (cGAS). The cGAS protein is a DNA sensor that produces cGAMP in response to detection of DNA in the cytosol (Burdette et al., (2011) Nature 478:515-518; Sun et al., (2013) Science 339:786-791; Diner et al., (2013) Cell Rep 3:1355-1361; Ablasser et al., (2013) Nature 498:380-384). - Upon binding to a CDN, STING dimerizes and undergoes a conformational change that promotes formation of a complex with TANK-binding kinase 1 (TBK1) (Ouyang et al., (2012) Immunity 36(6):1073-1086). This complex translocates to the perinuclear Golgi, resulting in delivery of TBK1 to endolysosomal compartments where it phosphorylates IRF3 and NF-1B transcription factors (Zhong et al., (2008) Immunity 29:538-550). A recent study has shown that STING functions as a scaffold by binding to both TBK1 and IRF3 to specifically promote the phosphorylation of IRF3 by TBK1 (Tanaka & Chen, (2012) Sci Signal 5(214):ra20). Activation of the IRF3-, IRF7- and NF-κB-dependent signaling pathways induces the production of cytokines and other immune response-related proteins, such as type I IFNs, which promote anti-pathogen and/or anti-tumor activity.
- A number of studies have investigated the use of CDN agonists of STING as potential vaccine adjuvants or immunomodulatory agents to elicit humoral and cellular immune responses (Dubensky et al., (2013) Ther Adv Vaccines 1(4):131-143 and references therein). Initial studies demonstrated that administration of the CDN c-di-GMP attenuated Staphylococcus aureus infection in vivo, reducing the number of recovered bacterial cells in a mouse infection model yet c-di-GMP had no observable inhibitory or bactericidal effect on bacterial cells in vitro suggesting the reduction in bacterial cells was due to an effect on the host immune system (Karaolis et al., (2005) Antimicrob Agents Chemother 49:1029-1038; Karaolis et al., (2007) Infect Immun 75:4942-4950). Recent studies have shown that synthetic CDN derivative molecules formulated with granulocyte-macrophage colony-stimulating factor (GM-CSF)-producing cancer vaccines (termed STINGVAX) elicit enhanced in vivo antitumor effects in therapeutic animal models of cancer as compared to immunization with GM-CSF vaccine alone (Fu et al., (2015) Sci Transl Med 7(283):283ra52), suggesting that CDN are potent vaccine adjuvants.
- Mutant STING proteins resulting from polymorphisms mapped to the human TMEM173 gene have been described exhibiting a gain-of function or constitutively active phenotype. When expressed in vitro, mutant STING alleles were shown to potently stimulate induction of type I IFN (Liu et al., (2014) N Engl J Med 371:507-518; Jeremiah et al., (2014) J Clin Invest 124:5516-5520; Dobbs et al., (2015) Cell Host Microbe 18(2):157-168; Tang & Wang, (2015) PLoS ONE 10(3):e0120090; Melki et al., (2017) J Allergy Clin Immunol In Press; Konig et al., (2017) Ann Rheum Dis 76(2):468-472; Burdette et al. (2011) Nature 478:515-518).

- The present disclosure provides mRNA (including mmRNA) encoding Interferon Regulatory Factors, such as IRF1, IRF3, IRF5, IRF7, IRF8, and IRF9 as immune potentiators. The IRF transcription factor family is involved in the regulation of gene expression leading to the production of type I interferons (IFNs) during innate immune responses. Nine human IRFs have been identified to date (IRF-1-IRF-9), with each family member sharing extensive sequence homology within their N-terminal binding domains (DBDs) (Mamane et al., (1999) Gene 237:1-14; Taniguchi et al., (2001) Annu Rev Immunol 19:623-655). Within the IRF family, IRF1, IRF3, IRF5, and IRF7 have been specifically implicated as positive regulators of type I IFN gene transcription (Honda et al., (2006) Immunity 25(3):349-360). IRF1 was the first family member discovered to activate type I IFN gene promoters (Miyamoto et al., (1988) Cell 54:903-913). Although studies show that IRF1 participates in type I IFN gene expression, normal induction of type I IFN was observed in virus-infected IRF1−/− murine fibroblasts, suggesting dispensability (Matsuyama et al., (1993) Cell 75:83-97). IRF5 was also shown to be dispensable for type I IFN induction by viruses or TLR agonists (Takaoka et al., (2005) Nature 434:243-249).
- Accordingly, in some aspects, the disclosure provides mRNA encoding constitutively active forms of human IRF1, IRF3, IRF5, IRF7, IRF8, and IRF9 as immune potentiators. In some aspects, the disclosure provides mRNA encoding constitutively active forms of human IRF3 and/or IRF7.
- During innate immune responses, IRF-3 plays a critical role in the early induction of type I IFNs. The IRF3 transcription factor is constitutively expressed and shuttles between the nucleus and cytoplasm of cells in latent form, with a predominantly cytosolic localization prior to phosphorylation (Hiscott (2007) J Biol Chem 282(21):15325-15329; Kumar et al., (2000) Mol Cell Biol 20(11):4159-4168). Upon phosphorylation of serine residues at the C-terminus by TBK-1 (
TANK binding kinase 1; also known as T2K and NAK) and/or IKKε (inducible IκB kinase; also known as IKKi), IRF3 translocates from the cytoplasm into the nucleus (Fitzgerald et al., (2003) Nat Immuno 4(5):491-496; Sharma et al., (2003) Science 300:1148-1151; Hemmi et al., (2004) J Exp Med 199:1641-1650). The transcriptional activity of IRF3 is mediated by these phosphorylation and translocation events. A model for IRF3 activation proposes that C-terminal phosphorylation induces a conformational change in IRF3 that promotes homo- and/or heterodimerization (e.g. with IRF7; see Honda et al., (2006) Immunity 25(3):346-360), nuclear localization, and association with the transcriptional co-activators CBP and/or p300 (Lin et al., (1999) Mol Cell Biol 19(4):2465-2474). While inactive IRF3 constitutively shuttles into and out of the nucleus, phosphorylated IRF3 proteins remain associated with CBP and/or p300, are retained in the nucleus, and induce transcription of IFN and other genes (Kumar et al., (2000) Mol Cell Biol 20(11):4159-4168). - In contrast to IRF3, IRF7 exhibits a low expression level in most cells, but is strongly induced by type I IFN-mediated signaling, supporting the notion that IRF3 is primarily responsible for the early induction of IFN genes and that IRF7 is involved in the late induction phase (Sato et al., (2000) Immunity 13(4):539-548). Ligand-binding to the type I IFN receptor results in the activation of a heterotrimeric transcriptional activator, termed IFN-stimulated gene factor 3 (ISGF3), which consists of IRF9, STAT1, and STAT2, and is responsible for the induction of the IRF7 gene (Marie et al., (1998) EMBO J 17(22):6660-6669). Like IRF3, IRF7 can partition between cytoplasm and nucleus after serine phosphorylation of its C-terminal region, allowing its dimerization and nuclear translocation. IRF7 forms a homodimer or a heterodimer with IRF3, and each of these different dimers differentially acts on the type I IFN gene family members. IRF3 is more potent in activating the IFN-β gene than the IFN-α genes, whereas IRF7 efficiently activates both IFN-α and IFN-β genes (Marie et al., (1998) EMBO J 17(22):6660-6669).

- mRNA Construct Components
- An mRNA may be a naturally or non-naturally occurring mRNA. An mRNA may include one or more modified nucleobases, nucleosides, or nucleotides, as described below, in which case it may be referred to as a “modified mRNA” or “mmRNA.” As described herein “nucleoside” is defined as a compound containing a sugar molecule (e.g., a pentose or ribose) or derivative thereof in combination with an organic base (e.g., a purine or pyrimidine) or a derivative thereof (also referred to herein as “nucleobase”). As described herein, “nucleotide” is defined as a nucleoside including a phosphate group.
- An mRNA may include a 5′ untranslated region (5′-UTR), a 3′ untranslated region (3′-UTR), and/or a coding region (e.g., an open reading frame). An exemplary 5′ UTR for use in the constructs is shown in SEQ ID NO: 21. An exemplary 3′ UTR for use in the constructs is shown in SEQ ID NO: 22. An exemplary 3′ UTR comprising miR-122 and miR-142.3p binding sites for use in the constructs is shown in SEQ ID NO: 23. An mRNA may include any suitable number of base pairs, including tens (e.g., 10, 20, 30, 40, 50, 60, 70, 80, 90 or 100), hundreds (e.g., 200, 300, 400, 500, 600, 700, 800, or 900) or thousands (e.g., 1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000, 9000, 10,000) of base pairs. Any number (e.g., all, some, or none) of nucleobases, nucleosides, or nucleotides may be an analog of a canonical species, substituted, modified, or otherwise non-naturally occurring. In certain embodiments, all of a particular nucleobase type may be modified.
- In some embodiments, an mRNA as described herein may include a 5′ cap structure, a chain terminating nucleotide, optionally a Kozak sequence (also known as a Kozak consensus sequence), a stem loop, a polyA sequence, and/or a polyadenylation signal.
- A 5′ cap structure or cap species is a compound including two nucleoside moieties joined by a linker and may be selected from a naturally occurring cap, a non-naturally occurring cap or cap analog, or an anti-reverse cap analog (ARCA). A cap species may include one or more modified nucleosides and/or linker moieties. For example, a natural mRNA cap may include a guanine nucleotide and a guanine (G) nucleotide methylated at the 7 position joined by a triphosphate linkage at their 5′ positions, e.g., m7G(5′)ppp(5′)G, commonly written as m7GpppG. A cap species may also be an anti-reverse cap analog. A non-limiting list of possible cap species includes m7GpppG, m7GpppmG,
m 73′dGpppG, m27,O3′GpppG, m2 7,O3′GppppG, m2 7,O2′GppppG, m7GpppmG, m7 3′dGpppG, m2 7O3′GpppG, m2 7O3′GppppG, and m2 7,O2′GppppG. - An mRNA may instead or additionally include a chain terminating nucleoside. For example, a chain terminating nucleoside may include those nucleosides deoxygenated at the 2′ and/or 3′ positions of their sugar group. Such species may include 3′-deoxyadenosine (cordycepin), 3′-deoxyuridine, 3′-deoxycytosine, 3′-deoxyguanosine, 3′-deoxythymine, and 2′,3′-dideoxynucleosides, such as 2′,3′-dideoxyadenosine, 2′,3′-dideoxyuridine, 2′,3′-dideoxycytosine, 2′,3′-dideoxyguanosine, and 2′,3′-dideoxythymine. In some embodiments, incorporation of a chain terminating nucleotide into an mRNA, for example at the 3′-terminus, may result in stabilization of the mRNA, as described, for example, in International Patent Publication No. WO 2013/103659.
- An mRNA may instead or additionally include a stem loop, such as a histone stem loop. A stem loop may include 2, 3, 4, 5, 6, 7, 8, or more nucleotide base pairs. For example, a stem loop may include 4, 5, 6, 7, or 8 nucleotide base pairs. A stem loop may be located in any region of an mRNA. For example, a stem loop may be located in, before, or after an untranslated region (a 5′ untranslated region or a 3′ untranslated region), a coding region, or a polyA sequence or tail. In some embodiments, a stem loop may affect one or more function(s) of an mRNA, such as initiation of translation, translation efficiency, and/or transcriptional termination.
- An mRNA may instead or additionally include a polyA sequence and/or polyadenylation signal. A polyA sequence may be comprised entirely or mostly of adenine nucleotides or analogs or derivatives thereof. A polyA sequence may be a tail located adjacent to a 3′ untranslated region of an mRNA. In some embodiments, a polyA sequence may affect the nuclear export, translation, and/or stability of an mRNA.
- An mRNA may instead or additionally include a microRNA binding site.
- In some embodiments, an mRNA is a bicistronic mRNA comprising a first coding region and a second coding region with an intervening sequence comprising an internal ribosome entry site (IRES) sequence that allows for internal translation initiation between the first and second coding regions, or with an intervening sequence encoding a self-cleaving peptide, such as a 2A peptide. IRES sequences and 2A peptides are typically used to enhance expression of multiple proteins from the same vector. A variety of IRES sequences are known and available in the art and may be used, including, e.g., the encephalomyocarditis virus IRES.
- In one embodiment, the polynucleotides of the present disclosure may include a sequence encoding a self-cleaving peptide. The self-cleaving peptide may be, but is not limited to, a 2A peptide. A variety of 2A peptides are known and available in the art and may be used, including e.g., the foot and mouth disease virus (FMDV) 2A peptide, the equine rhinitis A virus 2A peptide, the Thosea asigna virus 2A peptide, and the porcine teschovirus-1 2A peptide. 2A peptides are used by several viruses to generate two proteins from one transcript by ribosome-skipping, such that a normal peptide bond is impaired at the 2A peptide sequence, resulting in two discontinuous proteins being produced from one translation event. As a non-limiting example, the 2A peptide may have the protein sequence: GSGATNFSLLKQAGDVEENPGP (SEQ ID NO: 24), fragments or variants thereof. In one embodiment, the 2A peptide cleaves between the last glycine and last proline. As another non-limiting example, the polynucleotides of the present disclosure may include a polynucleotide sequence encoding the 2A peptide having the protein sequence GSGATNFSLLKQAGDVEENPGP (SEQ ID NO:24) fragments or variants thereof. One example of a polynucleotide sequence encoding the 2A peptide is: GGAAGCGGAGCTACTAACTTCAGCCTGCTGAAGCAGGCTGGAGACGTGGAGGAG AACCCTGGACCT (SEQ ID NO: 25). In one illustrative embodiment, a 2A peptide is encoded by the following sequence: 5′-TCCGGACTCAGATCCGGGGATCTCAAAATTGTCGCTCCTGTCAAACAAACTCTTA ACTTTGATTTACTCAAACTGGCTGGGGATGTAGAAAGCAATCCAGGTCCACTC-3′(SEQ ID NO: 26). The polynucleotide sequence of the 2A peptide may be modified or codon optimized by the methods described herein and/or are known in the art.
- In one embodiment, this sequence may be used to separate the coding regions of two or more polypeptides of interest. As a non-limiting example, the sequence encoding the F2A peptide may be between a first coding region A and a second coding region B (A-F2Apep-B). The presence of the F2A peptide results in the cleavage of the one long protein between the glycine and the proline at the end of the F2A peptide sequence (NPGP is cleaved to result in NPG and P) thus creating separate protein A (with 21 amino acids of the F2A peptide attached, ending with NPG) and separate protein B (with 1 amino acid, P, of the F2A peptide attached). Likewise, for other 2A peptides (P2A, T2A and E2A), the presence of the peptide in a long protein results in cleavage between the glycine and proline at the end of the 2A peptide sequence (NPGP is cleaved to result in NPG and P). Protein A and protein B may be the same or different peptides or polypeptides of interest. In particular embodiments, protein A is a polypeptide that induces immunogenic cell death and protein B is another polypeptide that stimulates an inflammatory and/or immune response and/or regulates immune responsiveness (as described further below).
- Modified mRNAs
- In some embodiments, an mRNA of the disclosure comprises one or more modified nucleobases, nucleosides, or nucleotides (termed “modified mRNAs” or “mmRNAs”). In some embodiments, modified mRNAs may have useful properties, including enhanced stability, intracellular retention, enhanced translation, and/or the lack of a substantial induction of the innate immune response of a cell into which the mRNA is introduced, as compared to a reference unmodified mRNA. Therefore, use of modified mRNAs may enhance the efficiency of protein production, intracellular retention of nucleic acids, as well as possess reduced immunogenicity.
- In some embodiments, an mRNA includes one or more (e.g., 1, 2, 3 or 4) different modified nucleobases, nucleosides, or nucleotides.

2.
- Where a single modification is listed, the listed nucleoside or nucleotide represents 100 percent of that A, U, G or C nucleotide or nucleoside having been modified. Where percentages are listed, these represent the percentage of that particular A, U, G or C nucleobase triphosphate of the total amount of A, U, G, or C triphosphate present. For example, the combination: 25% 5-Aminoallyl-CTP+75% CTP/25% 5-Methoxy-UTP+75% UTP refers to a polynucleotide where 25% of the cytosine triphosphates are 5-Aminoallyl-CTP while 75% of the cytosines are CTP; whereas 25% of the uracils are 5-methoxy UTP while 75% of the uracils are UTP. Where no modified UTP is listed then the naturally occurring ATP, UTP, GTP and/or CTP is used at 100% of the sites of those nucleotides found in the polynucleotide. In this example all of the GTP and ATP nucleotides are left unmodified.
- The mRNAs of the present disclosure, or regions thereof, may be codon optimized. Codon optimization methods are known in the art and may be useful for a variety of purposes: matching codon frequencies in host organisms to ensure proper folding, bias GC content to increase mRNA stability or reduce secondary structures, minimize tandem repeat codons or base runs that may impair gene construction or expression, customize transcriptional and translational control regions, insert or remove proteins trafficking sequences, remove/add post translation modification sites in encoded proteins (e.g., glycosylation sites), add, remove or shuffle protein domains, insert or delete restriction sites, modify ribosome binding sites and mRNA degradation sites, adjust translation rates to allow the various domains of the protein to fold properly, or to reduce or eliminate problem secondary structures within the polynucleotide. Codon optimization tools, algorithms and services are known in the art; non-limiting examples include services from GeneArt (Life Technologies), DNA2.0 (Menlo Park, Calif.) and/or proprietary methods. In one embodiment, the mRNA sequence is optimized using optimization algorithms, e.g., to optimize expression in mammalian cells or enhance mRNA stability.
- In certain embodiments, the present disclosure includes polynucleotides having at least 80%, at least 85%, at least 90%, at least 95%, at least 98%, or at least 99% sequence identity to any of the polynucleotide sequences described herein.
- mRNAs of the present disclosure may be produced by means available in the art, including but not limited to in vitro transcription (IVT) and synthetic methods. Enzymatic (IVT), solid-phase, liquid-phase, combined synthetic methods, small region synthesis, and ligation methods may be utilized. In one embodiment, mRNAs are made using IVT enzymatic synthesis methods. Methods of making polynucleotides by IVT are known in the art and are described in International Application PCT/US2013/30062, the contents of which are incorporated herein by reference in their entirety. Accordingly, the present disclosure also includes polynucleotides, e.g., DNA, constructs and vectors that may be used to in vitro transcribe an mRNA described herein.
- Non-natural modified nucleobases may be introduced into polynucleotides, e.g., mRNA, during synthesis or post-synthesis. In certain embodiments, modifications may be on internucleoside linkages, purine or pyrimidine bases, or sugar. In particular embodiments, the modification may be introduced at the terminal of a polynucleotide chain or anywhere else in the polynucleotide chain; with chemical synthesis or with a polymerase enzyme. Examples of modified nucleic acids and their synthesis are disclosed in PCT application No. PCT/US2012/058519. Synthesis of modified polynucleotides is also described in Verma and Eckstein, Annual Review of Biochemistry, vol. 76, 99-134 (1998).

- MicroRNA (miRNA) Binding Sites
- Polynucleotides of the disclosure can include regulatory elements, for example, microRNA (miRNA) binding sites, transcription factor binding sites, structured mRNA sequences and/or motifs, artificial binding sites engineered to act as pseudo-receptors for endogenous nucleic acid binding molecules, and combinations thereof. In some embodiments, polynucleotides including such regulatory elements are referred to as including “sensor sequences.” Non-limiting examples of sensor sequences are described in U.S. Publication 2014/0200261, the contents of which are incorporated herein by reference in their entirety.
- In some embodiments, a polynucleotide (e.g., a ribonucleic acid (RNA), e.g., a messenger RNA (mRNA)) of the disclosure comprises an open reading frame (ORF) encoding a polypeptide of interest and further comprises one or more miRNA binding site(s). Inclusion or incorporation of miRNA binding site(s) provides for regulation of polynucleotides of the disclosure, and in turn, of the polypeptides encoded therefrom, based on tissue-specific and/or cell-type specific expression of naturally-occurring miRNAs.
- A miRNA, e.g., a natural-occurring miRNA, is a 19-25 nucleotide long noncoding RNA that binds to a polynucleotide and down-regulates gene expression either by reducing stability or by inhibiting translation of the polynucleotide. A miRNA sequence comprises a “seed” region, i.e., a sequence in the region of positions 2-8 of the mature miRNA. A miRNA seed can comprise positions 2-8 or 2-7 of the mature miRNA. In some embodiments, a miRNA seed can comprise 7 nucleotides (e.g., nucleotides 2-8 of the mature miRNA), wherein the seed-complementary site in the corresponding miRNA binding site is flanked by an adenosine (A) opposed to
miRNA position 1. In some embodiments, a miRNA seed can comprise 6 nucleotides (e.g., nucleotides 2-7 of the mature miRNA), wherein the seed-complementary site in the corresponding miRNA binding site is flanked by an adenosine (A) opposed tomiRNA position 1. See, for example, Grimson A, Farh K K, Johnston W K, Garrett-Engele P, Lim L P, Bartel D P; Mol Cell. 2007 Jul. 6; 27(1):91-105. miRNA profiling of the target cells or tissues can be conducted to determine the presence or absence of miRNA in the cells or tissues. In some embodiments, a polynucleotide (e.g., a ribonucleic acid (RNA), e.g., a messenger RNA (mRNA)) of the disclosure comprises one or more microRNA binding sites, microRNA target sequences, microRNA complementary sequences, or microRNA seed complementary sequences. Such sequences can correspond to, e.g., have complementarity to, any known microRNA such as those taught in US Publication US2005/0261218 and US Publication US2005/0059005, the contents of each of which are incorporated herein by reference in their entirety. - As used herein, the term “microRNA (miRNA or miR) binding site” refers to a sequence within a polynucleotide, e.g., within a DNA or within an RNA transcript, including in the 5′UTR and/or 3′UTR, that has sufficient complementarity to all or a region of a miRNA to interact with, associate with or bind to the miRNA. In some embodiments, a polynucleotide of the disclosure comprising an ORF encoding a polypeptide of interest and further comprises one or more miRNA binding site(s). In exemplary embodiments, a 5′UTR and/or 3′UTR of the polynucleotide (e.g., a ribonucleic acid (RNA), e.g., a messenger RNA (mRNA)) comprises the one or more miRNA binding site(s).
- A miRNA binding site having sufficient complementarity to a miRNA refers to a degree of complementarity sufficient to facilitate miRNA-mediated regulation of a polynucleotide, e.g., miRNA-mediated translational repression or degradation of the polynucleotide. In exemplary aspects of the disclosure, a miRNA binding site having sufficient complementarity to the miRNA refers to a degree of complementarity sufficient to facilitate miRNA-mediated degradation of the polynucleotide, e.g., miRNA-guided RNA-induced silencing complex (RISC)-mediated cleavage of mRNA. The miRNA binding site can have complementarity to, for example, a 19-25 nucleotide miRNA sequence, to a 19-23 nucleotide miRNA sequence, or to a 22 nucleotide miRNA sequence. A miRNA binding site can be complementary to only a portion of a miRNA, e.g., to a portion less than 1, 2, 3, or 4 nucleotides of the full length of a naturally-occurring miRNA sequence. Full or complete complementarity (e.g., full complementarity or complete complementarity over all or a significant portion of the length of a naturally-occurring miRNA) is preferred when the desired regulation is mRNA degradation.
- In some embodiments, a miRNA binding site includes a sequence that has complementarity (e.g., partial or complete complementarity) with a miRNA seed sequence. In some embodiments, the miRNA binding site includes a sequence that has complete complementarity with a miRNA seed sequence. In some embodiments, a miRNA binding site includes a sequence that has complementarity (e.g., partial or complete complementarity) with an miRNA sequence. In some embodiments, the miRNA binding site includes a sequence that has complete complementarity with a miRNA sequence. In some embodiments, a miRNA binding site has complete complementarity with a miRNA sequence but for 1, 2, or 3 nucleotide substitutions, terminal additions, and/or truncations.
- In some embodiments, the miRNA binding site is the same length as the corresponding miRNA. In other embodiments, the miRNA binding site is one, two, three, four, five, six, seven, eight, nine, ten, eleven or twelve nucleotide(s) shorter than the corresponding miRNA at the 5′ terminus, the 3′ terminus, or both. In still other embodiments, the microRNA binding site is two nucleotides shorter than the corresponding microRNA at the 5′ terminus, the 3′ terminus, or both. The miRNA binding sites that are shorter than the corresponding miRNAs are still capable of degrading the mRNA incorporating one or more of the miRNA binding sites or preventing the mRNA from translation.
- In some embodiments, the miRNA binding site binds the corresponding mature miRNA that is part of an active RISC containing Dicer. In another embodiment, binding of the miRNA binding site to the corresponding miRNA in RISC degrades the mRNA containing the miRNA binding site or prevents the mRNA from being translated. In some embodiments, the miRNA binding site has sufficient complementarity to miRNA so that a RISC complex comprising the miRNA cleaves the polynucleotide comprising the miRNA binding site. In other embodiments, the miRNA binding site has imperfect complementarity so that a RISC complex comprising the miRNA induces instability in the polynucleotide comprising the miRNA binding site. In another embodiment, the miRNA binding site has imperfect complementarity so that a RISC complex comprising the miRNA represses transcription of the polynucleotide comprising the miRNA binding site.
- In some embodiments, the miRNA binding site has one, two, three, four, five, six, seven, eight, nine, ten, eleven or twelve mismatch(es) from the corresponding miRNA.
- In some embodiments, the miRNA binding site has at least about ten, at least about eleven, at least about twelve, at least about thirteen, at least about fourteen, at least about fifteen, at least about sixteen, at least about seventeen, at least about eighteen, at least about nineteen, at least about twenty, or at least about twenty-one contiguous nucleotides complementary to at least about ten, at least about eleven, at least about twelve, at least about thirteen, at least about fourteen, at least about fifteen, at least about sixteen, at least about seventeen, at least about eighteen, at least about nineteen, at least about twenty, or at least about twenty-one, respectively, contiguous nucleotides of the corresponding miRNA.
- By engineering one or more miRNA binding sites into a polynucleotide of the disclosure, the polynucleotide can be targeted for degradation or reduced translation, provided the miRNA in question is available. This can reduce off-target effects upon delivery of the polynucleotide. For example, if a polynucleotide of the disclosure is not intended to be delivered to a tissue or cell but ends up is said tissue or cell, then a miRNA abundant in the tissue or cell can inhibit the expression of the gene of interest if one or multiple binding sites of the miRNA are engineered into the 5′UTR and/or 3′UTR of the polynucleotide.
- Conversely, miRNA binding sites can be removed from polynucleotide sequences in which they naturally occur in order to increase protein expression in specific tissues. For example, a binding site for a specific miRNA can be removed from a polynucleotide to improve protein expression in tissues or cells containing the miRNA.
- In one embodiment, a polynucleotide of the disclosure can include at least one miRNA-binding site in the 5′UTR and/or 3′UTR in order to regulate cytotoxic or cytoprotective mRNA therapeutics to specific cells such as, but not limited to, normal and/or cancerous cells. In another embodiment, a polynucleotide of the disclosure can include two, three, four, five, six, seven, eight, nine, ten, or more miRNA-binding sites in the 5′-UTR and/or 3′-UTR in order to regulate cytotoxic or cytoprotective mRNA therapeutics to specific cells such as, but not limited to, normal and/or cancerous cells.
- Regulation of expression in multiple tissues can be accomplished through introduction or removal of one or more miRNA binding sites, e.g., one or more distinct miRNA binding sites. The decision whether to remove or insert a miRNA binding site can be made based on miRNA expression patterns and/or their profilings in tissues and/or cells in development and/or disease. Identification of miRNAs, miRNA binding sites, and their expression patterns and role in biology have been reported (e.g., Bonauer et al., Curr Drug Targets 2010 11:943-949; Anand and Cheresh Curr Opin Hematol 2011 18:171-176; Contreras and Rao Leukemia 2012 26:404-413 (2011 Dec. 20. doi: 10.1038/leu.2011.356); Bartel Cell 2009 136:215-233; Landgraf et al, Cell, 2007 129:1401-1414; Gentner and Naldini, Tissue Antigens. 2012 80:393-403 and all references therein; each of which is incorporated herein by reference in its entirety).
- miRNAs and miRNA binding sites can correspond to any known sequence, including non-limiting examples described in U.S. Publication Nos. 2014/0200261, 2005/0261218, and 2005/0059005, each of which are incorporated herein by reference in their entirety.
- Examples of tissues where miRNA are known to regulate mRNA, and thereby protein expression, include, but are not limited to, liver (miR-122), muscle (miR-133, miR-206, miR-208), endothelial cells (miR-17-92, miR-126), myeloid cells (miR-142-3p, miR-142-5p, miR-16, miR-21, miR-223, miR-24, miR-27), adipose tissue (let-7, miR-30c), heart (miR-1d, miR-149), kidney (miR-192, miR-194, miR-204), and lung epithelial cells (let-7, miR-133, miR-126).
- Specifically, miRNAs are known to be differentially expressed in immune cells (also called hematopoietic cells), such as antigen presenting cells (APCs) (e.g., dendritic cells and macrophages), macrophages, monocytes, B lymphocytes, T lymphocytes, granulocytes, natural killer cells, etc. Immune cell specific miRNAs are involved in immunogenicity, autoimmunity, the immune response to infection, inflammation, as well as unwanted immune response after gene therapy and tissue/organ transplantation. Immune cell specific miRNAs also regulate many aspects of development, proliferation, differentiation and apoptosis of hematopoietic cells (immune cells). For example, miR-142 and miR-146 are exclusively expressed in immune cells, particularly abundant in myeloid dendritic cells. It has been demonstrated that the immune response to a polynucleotide can be shut-off by adding miR-142 binding sites to the 3′-UTR of the polynucleotide, enabling more stable gene transfer in tissues and cells. miR-142 efficiently degrades exogenous polynucleotides in antigen presenting cells and suppresses cytotoxic elimination of transduced cells (e.g., Annoni A et al., blood, 2009, 114, 5152-5161; Brown B D, et al., Nat med. 2006, 12(5), 585-591; Brown B D, et al., blood, 2007, 110(13): 4144-4152, each of which is incorporated herein by reference in its entirety).
- An antigen-mediated immune response can refer to an immune response triggered by foreign antigens, which, when entering an organism, are processed by the antigen presenting cells and displayed on the surface of the antigen presenting cells. T cells can recognize the presented antigen and induce a cytotoxic elimination of cells that express the antigen.
- Introducing a miR-142 binding site into the 5′UTR and/or 3′UTR of a polynucleotide of the disclosure can selectively repress gene expression in antigen presenting cells through miR-142 mediated degradation, limiting antigen presentation in antigen presenting cells (e.g., dendritic cells) and thereby preventing antigen-mediated immune response after the delivery of the polynucleotide. The polynucleotide is then stably expressed in target tissues or cells without triggering cytotoxic elimination.
- In one embodiment, binding sites for miRNAs that are known to be expressed in immune cells, in particular, antigen presenting cells, can be engineered into a polynucleotide of the disclosure to suppress the expression of the polynucleotide in antigen presenting cells through miRNA mediated RNA degradation, subduing the antigen-mediated immune response. Expression of the polynucleotide is maintained in non-immune cells where the immune cell specific miRNAs are not expressed. For example, in some embodiments, to prevent an immunogenic reaction against a liver specific protein, any miR-122 binding site can be removed and a miR-142 (and/or mirR-146) binding site can be engineered into the 5′UTR and/or 3′UTR of a polynucleotide of the disclosure.
- To further drive the selective degradation and suppression in APCs and macrophage, a polynucleotide of the disclosure can include a further negative regulatory element in the 5′UTR and/or 3′UTR, either alone or in combination with miR-142 and/or miR-146 binding sites. As a non-limiting example, the further negative regulatory element is a Constitutive Decay Element (CDE).

Furthermore, novel miRNAs can be identified in immune cell through micro-array hybridization and microtome analysis (e.g., Jima D D et al, Blood, 2010, 116:e118-e127; Vaz C et al., BMC Genomics, 2010, 11,288, the content of each of which is incorporated herein by reference in its entirety.)
- miRNAs that are known to be expressed in the liver include, but are not limited to, miR-107, miR-122-3p, miR-122-5p, miR-1228-3p, miR-1228-5p, miR-1249, miR-129-5p, miR-1303, miR-151a-3p, miR-151a-5p, miR-152, miR-194-3p, miR-194-5p, miR-199a-3p, miR-199a-5p, miR-199b-3p, miR-199b-5p, miR-296-5p, miR-557, miR-581, miR-939-3p, and miR-939-5p. miRNA binding sites from any liver specific miRNA can be introduced to or removed from a polynucleotide of the disclosure to regulate expression of the polynucleotide in the liver. Liver specific miRNA binding sites can be engineered alone or further in combination with immune cell (e.g., APC) miRNA binding sites in a polynucleotide of the disclosure.

- In addition, a large group of miRNAs are enriched in embryonic stem cells, controlling stem cell self-renewal as well as the development and/or differentiation of various cell lineages, such as neural cells, cardiac, hematopoietic cells, skin cells, osteogenic cells and muscle cells (e.g., Kuppusamy K T et al., Curr. Mol Med, 2013, 13(5), 757-764; Vidigal J A and Ventura A, Semin Cancer Biol. 2012, 22(5-6), 428-436; Goff L A et al., PLoS One, 2009, 4:e7192; Morin R D et al., Genome Res, 2008,18, 610-621; Yoo J K et al., Stem Cells Dev. 2012, 21(11), 2049-2057, each of which is incorporated herein by reference in its entirety). miRNAs abundant in embryonic stem cells include, but are not limited to, let-7a-2-3p, let-a-3p, let-7a-5p, let7d-3p, let-7d-5p, miR-103a-2-3p, miR-103a-5p, miR-106b-3p, miR-106b-5p, miR-1246, miR-1275, miR-138-1-3p, miR-138-2-3p, miR-138-5p, miR-154-3p, miR-154-5p, miR-200c-3p, miR-200c-5p, miR-290, miR-301a-3p, miR-301a-5p, miR-302a-3p, miR-302a-5p, miR-302b-3p, miR-302b-5p, miR-302c-3p, miR-302c-5p, miR-302d-3p, miR-302d-5p, miR-302e, miR-367-3p, miR-367-5p, miR-369-3p, miR-369-5p, miR-370, miR-371, miR-373, miR-380-5p, miR-423-3p, miR-423-5p, miR-486-5p, miR-520c-3p, miR-548e, miR-548f, miR-548g-3p, miR-548g-5p, miR-548i, miR-548k, miR-5481, miR-548m, miR-548n, miR-548o-3p, miR-548o-5p, miR-548p, miR-664a-3p, miR-664a-5p, miR-664b-3p, miR-664b-5p, miR-766-3p, miR-766-5p, miR-885-3p, miR-885-5p, miR-93-3p, miR-93-5p, miR-941,miR-96-3p, miR-96-5p, miR-99b-3p and miR-99b-5p. Many predicted novel miRNAs are discovered by deep sequencing in human embryonic stem cells (e.g., Morin R D et al., Genome Res, 2008,18, 610-621; Goff L A et al., PLoS One, 2009, 4:e7192; Bar M et al., Stem cells, 2008, 26, 2496-2505, the content of each of which is incorporated herein by reference in its entirety).
- In one embodiment, the binding sites of embryonic stem cell specific miRNAs can be included in or removed from the 3′UTR of a polynucleotide of the disclosure to modulate the development and/or differentiation of embryonic stem cells, to inhibit the senescence of stem cells in a degenerative condition (e.g. degenerative diseases), or to stimulate the senescence and apoptosis of stem cells in a disease condition (e.g. cancer stem cells).
- Many miRNA expression studies are conducted to profile the differential expression of miRNAs in various cancer cells/tissues and other diseases. Some miRNAs are abnormally over-expressed in certain cancer cells and others are under-expressed. For example, miRNAs are differentially expressed in cancer cells (WO2008/154098, US2013/0059015, US2013/0042333, WO2011/157294); cancer stem cells (US2012/0053224); pancreatic cancers and diseases (US2009/0131348, US2011/0171646, US2010/0286232, U.S. Pat. No. 8,389,210); asthma and inflammation (U.S. Pat. No. 8,415,096); prostate cancer (US2013/0053264); hepatocellular carcinoma (WO2012/151212, US2012/0329672, WO2008/054828, U.S. Pat. No. 8,252,538); lung cancer cells (WO2011/076143, WO2013/033640, WO2009/070653, US2010/0323357); cutaneous T cell lymphoma (WO2013/011378); colorectal cancer cells (WO2011/0281756, WO2011/076142); cancer positive lymph nodes (WO2009/100430, US2009/0263803); nasopharyngeal carcinoma (EP2112235); chronic obstructive pulmonary disease (US2012/0264626, US2013/0053263); thyroid cancer (WO2013/066678); ovarian cancer cells (US2012/0309645, WO2011/095623); breast cancer cells (WO2008/154098, WO2007/081740, US2012/0214699), leukemia and lymphoma (WO2008/073915, US2009/0092974, US2012/0316081, US2012/0283310, WO2010/018563), the content of each of which is incorporated herein by reference in its entirety.
- As a non-limiting example, miRNA binding sites for miRNAs that are over-expressed in certain cancer and/or tumor cells can be removed from the 3′UTR of a polynucleotide of the disclosure, restoring the expression suppressed by the over-expressed miRNAs in cancer cells, thus ameliorating the corresponsive biological function, for instance, transcription stimulation and/or repression, cell cycle arrest, apoptosis and cell death. Normal cells and tissues, wherein miRNAs expression is not up-regulated, will remain unaffected.
- miRNA can also regulate complex biological processes such as angiogenesis (e.g., miR-132) (Anand and Cheresh Curr Opin Hematol 2011 18:171-176). In the polynucleotides of the disclosure, miRNA binding sites that are involved in such processes can be removed or introduced, in order to tailor the expression of the polynucleotides to biologically relevant cell types or relevant biological processes. In this context, the polynucleotides of the disclosure are defined as auxotrophic polynucleotides.
- In some embodiments, the therapeutic window and/or differential expression (e.g., tissue-specific expression) of a polypeptide of the disclosure may be altered by incorporation of a miRNA binding site into an mRNA encoding the polypeptide. In one example, an mRNA may include one or more miRNA binding sites that are bound by miRNAs that have higher expression in one tissue type as compared to another. In another example, an mRNA may include one or more miRNA binding sites that are bound by miRNAs that have lower expression in a cancer cell as compared to a non-cancerous cell of the same tissue of origin. When present in a cancer cell that expresses low levels of such an miRNA, the polypeptide encoded by the mRNA typically will show increased expression.
- Liver cancer cells (e.g., hepatocellular carcinoma cells) typically express low levels of miR-122 as compared to normal liver cells. Therefore, an mRNA encoding a polypeptide that includes at least one miR-122 binding site (e.g., in the 3′-UTR of the mRNA) will typically express comparatively low levels of the polypeptide in normal liver cells and comparatively high levels of the polypeptide in liver cancer cells.
- In some embodiments, the mRNA includes at least one miR-122 binding site, at least two miR-122 binding sites, at least three miR-122 binding sites, at least four miR-122 binding sites, or at least five miR-122 binding sites. In one aspect, the miRNA binding site binds miR-122 or is complementary to miR-122. In another aspect, the miRNA binding site binds to miR-122-3p or miR-122-5p. In a particular aspect, the miRNA binding site comprises a nucleotide sequence at least 80%, at least 85%, at least 90%, at least 95%, or 100% identical to SEQ ID NO: 175, wherein the miRNA binding site binds to miR-122. In another particular aspect, the miRNA binding site comprises a nucleotide sequence at least 80%, at least 85%, at least 90%, at least 95%, or 100% identical to SEQ ID NO: 173, wherein the miRNA binding site binds to miR-122. These sequences are shown below in Table 3.
- In some embodiments, a polynucleotide of the disclosure comprises a miRNA binding site, wherein the miRNA binding site comprises one or more nucleotide sequences selected from Table 3, including one or more copies of any one or more of the miRNA binding site sequences. In some embodiments, a polynucleotide of the disclosure further comprises at least one, two, three, four, five, six, seven, eight, nine, ten, or more of the same or different miRNA binding sites selected from Table 3, including any combination thereof. In some embodiments, the miRNA binding site binds to miR-142 or is complementary to miR-142. In some embodiments, the miR-142 comprises SEQ ID NO: 27. In some embodiments, the miRNA binding site binds to miR-142-3p or miR-142-5p. In some embodiments, the miR-142-3p binding site comprises SEQ ID NO: 29. In some embodiments, the miR-142-5p binding site comprises SEQ ID NO: 31. In some embodiments, the miRNA binding site comprises a nucleotide sequence at least 80%, at least 85%, at least 90%, at least 95%, or 100% identical to SEQ ID NO: 29 or SEQ ID NO: 31.

In some embodiments, the 5′UTR comprises amiRNA binding site. In some embodiments, the 3′UTR comprises amiRNA binding site. In some embodiments, the 5′UTR and the 3′UTR comprise a miRNA binding site. The insertion site in the polynucleotide can be anywhere in the polynucleotide as long as the insertion of the miRNA binding site in the polynucleotide does not interfere with the translation of afunctional polypeptide in the absence of the corresponding miRNA; and in the presence of the miRNA, the insertion of the miRNA binding site in the polynucleotide and the binding of the miRNA binding site to the corresponding miRNA are capable of degrading the polynucleotide or preventing the translation of the polynucleotide.
- In some embodiments, amiRNA binding site is inserted in at least about 30 nucleotides downstream from the stop codon of an ORF in a polynucleotide of the disclosure comprising the ORF. In some embodiments, amiRNA binding site is inserted in at least about 10 nucleotides, at least about 15 nucleotides, at least about 20 nucleotides, at least about 25 nucleotides, at least about 30 nucleotides, at least about 35 nucleotides, at least about 40 nucleotides, at least about 45 nucleotides, at least about 50 nucleotides, at least about 55 nucleotides, at least about 60 nucleotides, at least about 65 nucleotides, at least about 70 nucleotides, at least about 75 nucleotides, at least about 80 nucleotides, at least about 85 nucleotides, at least about 90 nucleotides, at least about 95 nucleotides, or at least about 100 nucleotides downstream from the stop codon of an ORF in a polynucleotide of the disclosure. In some embodiments, a miRNA binding site is inserted in about 10 nucleotides to about 100 nucleotides, about 20 nucleotides to about 90 nucleotides, about 30 nucleotides to about 80 nucleotides, about 40 nucleotides to about 70 nucleotides, about 50 nucleotides to about 60 nucleotides, about 45 nucleotides to about 65 nucleotides downstream from the stop codon of an ORF in a polynucleotide of the disclosure.
- miRNA gene regulation can be influenced by the sequence surrounding the miRNA such as, but not limited to, the species of the surrounding sequence, the type of sequence (e.g., heterologous, homologous, exogenous, endogenous, or artificial), regulatory elements in the surrounding sequence and/or structural elements in the surrounding sequence. The miRNA can be influenced by the 5′UTR and/or 3′UTR. As a non-limiting example, a non-human 3′UTR can increase the regulatory effect of the miRNA sequence on the expression of a polypeptide of interest compared to a human 3′UTR of the same sequence type.
- In one embodiment, other regulatory elements and/or structural elements of the 5′UTR can influence miRNA mediated gene regulation. One example of a regulatory element and/or structural element is a structured IRES (Internal Ribosome Entry Site) in the 5′UTR, which is necessary for the binding of translational elongation factors to initiate protein translation. EIF4A2 binding to this secondarily structured element in the 5′-UTR is necessary for miRNA mediated gene expression (Meijer H A et al., Science, 2013, 340, 82-85, incorporated herein by reference in its entirety). The polynucleotides of the disclosure can further include this structured 5′UTR in order to enhance microRNA mediated gene regulation.
- At least one miRNA binding site can be engineered into the 3′UTR of a polynucleotide of the disclosure. In this context, at least two, at least three, at least four, at least five, at least six, at least seven, at least eight, at least nine, at least ten, or more miRNA binding sites can be engineered into a 3′UTR of a polynucleotide of the disclosure. For example, 1 to 10, 1 to 9, 1 to 8, 1 to 7, 1 to 6, 1 to 5, 1 to 4, 1 to 3, 2, or 1 miRNA binding sites can be engineered into the 3′UTR of a polynucleotide of the disclosure. In one embodiment, miRNA binding sites incorporated into a polynucleotide of the disclosure can be the same or can be different miRNA sites. A combination of different miRNA binding sites incorporated into a polynucleotide of the disclosure can include combinations in which more than one copy of any of the different miRNA sites are incorporated. In another embodiment, miRNA binding sites incorporated into a polynucleotide of the disclosure can target the same or different tissues in the body. As a non-limiting example, through the introduction of tissue-, cell-type-, or disease-specific miRNA binding sites in the 3′-UTR of a polynucleotide of the disclosure, the degree of expression in specific cell types (e.g., hepatocytes, myeloid cells, endothelial cells, cancer cells, etc.) can be reduced.
- In one embodiment, a miRNA binding site can be engineered near the 5′ terminus of the 3′UTR, about halfway between the 5′ terminus and 3′ terminus of the 3′UTR and/or near the 3′ terminus of the 3′UTR in a polynucleotide of the disclosure. As a non-limiting example, a miRNA binding site can be engineered near the 5′ terminus of the 3′UTR and about halfway between the 5′ terminus and 3′ terminus of the 3′UTR. As another non-limiting example, a miRNA binding site can be engineered near the 3′ terminus of the 3′UTR and about halfway between the 5′ terminus and 3′ terminus of the 3′UTR. As yet another non-limiting example, a miRNA binding site can be engineered near the 5′ terminus of the 3′UTR and near the 3′ terminus of the 3′UTR.
- In another embodiment, a 3′UTR can comprise 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 miRNA binding sites. The miRNA binding sites can be complementary to a miRNA, miRNA seed sequence, and/or miRNA sequences flanking the seed sequence.
- In one embodiment, a polynucleotide of the disclosure can be engineered to include more than one miRNA site expressed in different tissues or different cell types of a subject. As a non-limiting example, a polynucleotide of the disclosure can be engineered to include miR-192 and miR-122 to regulate expression of the polynucleotide in the liver and kidneys of a subject. In another embodiment, a polynucleotide of the disclosure can be engineered to include more than one miRNA site for the same tissue.
- In some embodiments, the therapeutic window and or differential expression associated with the polypeptide encoded by a polynucleotide of the disclosure can be altered with a miRNA binding site. For example, a polynucleotide encoding a polypeptide that provides a death signal can be designed to be more highly expressed in cancer cells by virtue of the miRNA signature of those cells. Where a cancer cell expresses a lower level of a particular miRNA, the polynucleotide encoding the binding site for that miRNA (or miRNAs) would be more highly expressed. Hence, the polypeptide that provides a death signal triggers or induces cell death in the cancer cell. Neighboring noncancer cells, harboring a higher expression of the same miRNA would be less affected by the encoded death signal as the polynucleotide would be expressed at a lower level due to the effects of the miRNA binding to the binding site or “sensor” encoded in the 3′UTR. Conversely, cell survival or cytoprotective signals can be delivered to tissues containing cancer and non-cancerous cells where a miRNA has a higher expression in the cancer cells—the result being a lower survival signal to the cancer cell and a larger survival signal to the normal cell. Multiple polynucleotides can be designed and administered having different signals based on the use of miRNA binding sites as described herein.
- In some embodiments, the expression of a polynucleotide of the disclosure can be controlled by incorporating at least one sensor sequence in the polynucleotide and formulating the polynucleotide for administration. As a non-limiting example, a polynucleotide of the disclosure can be targeted to a tissue or cell by incorporating a miRNA binding site and formulating the polynucleotide in a lipid nanoparticle comprising a cationic lipid, including any of the lipids described herein.
- A polynucleotide of the disclosure can be engineered for more targeted expression in specific tissues, cell types, or biological conditions based on the expression patterns of miRNAs in the different tissues, cell types, or biological conditions. Through introduction of tissue-specific miRNA binding sites, a polynucleotide of the disclosure can be designed for optimal protein expression in a tissue or cell, or in the context of a biological condition.
- In some embodiments, a polynucleotide of the disclosure can be designed to incorporate miRNA binding sites that either have 100% identity to known miRNA seed sequences or have less than 100% identity to miRNA seed sequences. In some embodiments, a polynucleotide of the disclosure can be designed to incorporate miRNA binding sites that have at least: 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, or 99% identity to known miRNA seed sequences. The miRNA seed sequence can be partially mutated to decrease miRNA binding affinity and as such result in reduced downmodulation of the polynucleotide. In essence, the degree of match or mis-match between the miRNA binding site and the miRNA seed can act as a rheostat to more finely tune the ability of the miRNA to modulate protein expression. In addition, mutation in the non-seed region of a miRNA binding site can also impact the ability of a miRNA to modulate protein expression.
- In one embodiment, a miRNA sequence can be incorporated into the loop of a stem loop.
- In another embodiment, a miRNA seed sequence can be incorporated in the loop of a stem loop and a miRNA binding site can be incorporated into the 5′ or 3′ stem of the stem loop.
- In one embodiment, a translation enhancer element (TEE) can be incorporated on the 5′end of the stem of a stem loop and a miRNA seed can be incorporated into the stem of the stem loop. In another embodiment, a TEE can be incorporated on the 5′ end of the stem of a stem loop, a miRNA seed can be incorporated into the stem of the stem loop and a miRNA binding site can be incorporated into the 3′ end of the stem or the sequence after the stem loop. The miRNA seed and the miRNA binding site can be for the same and/or different miRNA sequences.
- In one embodiment, the incorporation of a miRNA sequence and/or a TEE sequence changes the shape of the stem loop region which can increase and/or decrease translation. (see e.g, Kedde et al., “A Pumilio-induced RNA structure switch in p27-3′UTR controls miR-221 and miR-22 accessibility.” Nature Cell Biology. 2010, incorporated herein by reference in its entirety).
- In one embodiment, the 5′-UTR of a polynucleotide of the disclosure can comprise at least one miRNA sequence. The miRNA sequence can be, but is not limited to, a 19 or 22 nucleotide sequence and/or a miRNA sequence without the seed.
- In one embodiment the miRNA sequence in the 5′UTR can be used to stabilize a polynucleotide of the disclosure described herein.
- In another embodiment, a miRNA sequence in the 5′UTR of a polynucleotide of the disclosure can be used to decrease the accessibility of the site of translation initiation such as, but not limited to a start codon. See, e.g., Matsuda et al., PLoS One. 2010 11(5):e15057; incorporated herein by reference in its entirety, which used antisense locked nucleic acid (LNA) oligonucleotides and exon-junction complexes (EJCs) around a start codon (−4 to +37 where the A of the AUG codons is +1) in order to decrease the accessibility to the first start codon (AUG). Matsuda showed that altering the sequence around the start codon with an LNA or EJC affected the efficiency, length and structural stability of a polynucleotide. A polynucleotide of the disclosure can comprise a miRNA sequence, instead of the LNA or EJC sequence described by Matsuda et al, near the site of translation initiation in order to decrease the accessibility to the site of translation initiation. The site of translation initiation can be prior to, after or within the miRNA sequence. As a non-limiting example, the site of translation initiation can be located within a miRNA sequence such as a seed sequence or binding site. As another non-limiting example, the site of translation initiation can be located within a miR-122 sequence such as the seed sequence or the mir-122 binding site.
- In some embodiments, a polynucleotide of the disclosure can include at least one miRNA in order to dampen the antigen presentation by antigen presenting cells. The miRNA can be the complete miRNA sequence, the miRNA seed sequence, the miRNA sequence without the seed, or a combination thereof. As a non-limiting example, a miRNA incorporated into a polynucleotide of the disclosure can be specific to the hematopoietic system. As another non-limiting example, a miRNA incorporated into a polynucleotide of the disclosure to dampen antigen presentation is miR-142-3p.
- In some embodiments, a polynucleotide of the disclosure can include at least one miRNA in order to dampen expression of the encoded polypeptide in a tissue or cell of interest. As a non-limiting example, a polynucleotide of the disclosure can include at least one miR-122 binding site in order to dampen expression of an encoded polypeptide of interest in the liver. As another non-limiting example a polynucleotide of the disclosure can include at least one miR-142-3p binding site, miR-142-3p seed sequence, miR-142-3p binding site without the seed, miR-142-5p binding site, miR-142-5p seed sequence, miR-142-5p binding site without the seed, miR-146 binding site, miR-146 seed sequence and/or miR-146 binding site without the seed sequence.
- In some embodiments, a polynucleotide of the disclosure can comprise at least one miRNA binding site in the 3′UTR in order to selectively degrade mRNA therapeutics in the immune cells to subdue unwanted immunogenic reactions caused by therapeutic delivery.

- In another embodiment, the sequence of the GC-rich RNA element is comprised exclusively of guanine (G) and cytosine (C) nucleobases.
- RNA elements that provide a desired translational regulatory activity as described herein can be identified and characterized using known techniques, such as ribosome profiling. Ribosome profiling is a technique that allows the determination of the positions of PICs and/or ribosomes bound to mRNAs (see e.g., Ingolia et al., (2009) Science 324(5924):218-23, incorporated herein by reference). The technique is based on protecting a region or segment of mRNA, by the PIC and/or ribosome, from nuclease digestion. Protection results in the generation of a 30-bp fragment of RNA termed a ‘footprint’. The sequence and frequency of RNA footprints can be analyzed by methods known in the art (e.g., RNA-seq). The footprint is roughly centered on the A-site of the ribosome. If the PIC or ribosome dwells at a particular position or location along an mRNA, footprints generated at these position would be relatively common. Studies have shown that more footprints are generated at positions where the PIC and/or ribosome exhibits decreased processivity and fewer footprints where the PIC and/or ribosome exhibits increased processivity (Gardin et al., (2014) eLife 3:e03735). In some embodiments, residence time or the time of occupancy of a the PIC or ribosome at a discrete position or location along an polynucleotide comprising any one or more of the RNA elements described herein is determined by ribosome profiling.
- In order to enhance the purity of synthetically produced RNA, modified in vitro transcription (IVT) processes which produce RNA preparations having vastly different properties from RNA produced using a traditional IVT process may be used. The RNA preparations produced according to these methods have properties that enable the production of qualitatively and quantitatively superior compositions. Even when coupled with extensive purification processes, RNA produced using traditional IVT methods is qualitatively and quantitatively distinct from the RNA preparations produced by the modified IVT processes. For instance, the purified RNA preparations are less immunogenic in comparison to RNA preparations made using traditional IVT. Additionally, increased protein expression levels with higher purity are produced from the purified RNA preparations.
- Traditional IVT reactions are performed by incubating a DNA template with an RNA polymerase and equimolar quantities of nucleotide triphosphates, including GTP, ATP, CTP, and UTP in a transcription buffer. An RNA transcript having a 5′ terminal guanosine triphosphate is produced from this reaction. These reactions also result in the production of a number of impurities such as double stranded and single stranded RNAs which are immunostimulatory and may have an additive impact. The purity methods described herein prevent formation of reverse complements and thus prevent the innate immune recognition of both species. In some embodiments the modified IVT methods result in the production of RNA having significantly reduced T cell activity than an RNA preparation made using prior art methods with equimolar NTPs. The prior art attempts to remove these undesirable components using a series of subsequent purification steps. Such purification methods are undesirable because they involve additional time and resources and also result in the incorporation of residual organic solvents in the final product, which is undesirable for a pharmaceutical product. It is labor and capital intensive to scale up processes like reverse phase chromatography (RP): utilizing for instance explosion proof facilities, HPLC columns and purification systems rated for high pressure, high temperature, flammable solvents etc. The scale and throughput for large scale manufacture are limited by these factors. Subsequent purification is also required to remove alkylammonium ion pair utilized in RP process. In contrast the methods described herein even enhance currently utilized methods (eg RP). Lower impurity load leads to higher purification recovery of full length RNA devoid of cytokine inducing contaminants eg. higher quality of materials at the outset.
- The modified IVT methods involve the manipulation of one or more of the reaction parameters in the IVT reaction to produce a RNA preparation of highly functional RNA without one or more of the undesirable contaminants produced using the prior art processes. One parameter in the IVT reaction that may be manipulated is the relative amount of a nucleotide or nucleotide analog in comparison to one or more other nucleotides or nucleotide analogs in the reaction mixture (e.g., disparate nucleotide amounts or concentration). For instance, the IVT reaction may include an excess of a nucleotides, e.g., nucleotide monophosphate, nucleotide diphosphate or nucleotide triphosphate and/or an excess of nucleotide analogs and/or nucleoside analogs. The methods produce a high yield product which is significantly more pure than products produced by traditional IVT methods.
- Nucleotide analogs are compounds that have the general structure of a nucleotide or are structurally similar to a nucleotide or portion thereof. In particular, nucleotide analogs are nucleotides which contain, for example, an analogue of the nucleic acid portion, sugar portion and/or phosphate groups of the nucleotide. Nucleotides include, for instance, nucleotide monophosphates, nucleotide diphosphates, and nucleotide triphosphates. A nucleotide analog, as used herein is structurally similar to a nucleotide or portion thereof but does not have the typical nucleotide structure (nucleobase-ribose-phosphate). Nucleoside analogs are compounds that have the general structure of a nucleoside or are structurally similar to a nucleoside or portion thereof. In particular, nucleoside analogs are nucleosides which contain, for example, an analogue of the nucleic acid and/or sugar portion of the nucleoside.
- The nucleotide analogs useful in the methods are structurally similar to nucleotides or portions thereof but, for example, are not polymerizable by T7. Nucleotide/nucleoside analogs as used herein (including C, T, A, U, G, dC, dT, dA, dU, or dG analogs) include for instance, antiviral nucleotide analogs, phosphate analogs (soluble or immobilized, hydrolyzable or non-hydrolyzable), dinucleotide, trinucleotide, tetranucleotide, e.g., a cap analog, or a precursor/substrate for enzymatic capping (vaccinia, or ligase), a nucleotide labelled with a functional group to facilitate ligation/conjugation of cap or 5′ moiety (IRES), a nucleotide labelled with a 5′ P04 to facilitate ligation of cap or 5′ moiety, or a nucleotide labelled with a functional group/protecting group that can be chemically or enzymatically cleavable. Antiviral nucleotide/nucleoside analogs include but are not limited to Ganciclovir, Entecavir, Telbivudine, Vidarabine and Cidofovir.
- The IVT reaction typically includes the following: an RNA polymerase, e.g., a T7 RNA polymerase at a final concentration of, e.g., 1000-12000 U/mL, e.g., 7000 U/mL; the DNA template at a final concentration of, e.g., 10-70 nM, e.g., 40 nM; nucleotides (NTPs) at a final concentration of e.g., 0.5-10 mM, e.g., 7.5 mM each; magnesium at a final concentration of, e.g., 12-60 mM, e.g., magnesium acetate at 40 mM; a buffer such as, e.g., HEPES or Tris at a pH of, e.g., 7-8.5, e.g. 40 mM Tris HCl,
pH 8. In someembodiments 5 mM dithiothreitol (DTT) and/or 1 mM spermidine may be included. In some embodiments, an RNase inhibitor is included in the IVT reaction to ensure no RNase induced degradation during the transcription reaction. For example, murine RNase inhibitor can be utilized at a final concentration of 1000 U/mL. In some embodiments a pyrophosphatase is included in the IVT reaction to cleave the inorganic pyrophosphate generated following each nucleotide incorporation into two units of inorganic phosphate. This ensures that magnesium remains in solution and does not precipitate as magnesium pyrophosphate. For example, an E. coli inorganic pyrophosphatase can be utilized at a final concentration of 1 U/mL. - Similar to traditional methods, the modified method may also be produced by forming a reaction mixture comprising a DNA template, and one or more NTPs such as ATP, CTP, UTP, GTP (or corresponding analog of aforementioned components) and a buffer. The reaction is then incubated under conditions such that the RNA is transcribed. However, the modified methods utilize the presence of an excess amount of one or more nucleotides and/or nucleotide analogs that can have significant impact on the end product. These methods involve a modification in the amount (e.g., molar amount or quantity) of nucleotides and/or nucleotide analogs in the reaction mixture. In some aspects, one or more nucleotides and/or one or more nucleotide analogs may be added in excess to the reaction mixture. An excess of nucleotides and/or nucleotide analogs is any amount greater than the amount of one or more of the other nucleotides such as NTPs in the reaction mixture. For instance, an excess of a nucleotide and/or nucleotide analog may be a greater amount than the amount of each or at least one of the other individual NTPs in the reaction mixture or may refer to an amount greater than equimolar amounts of the other NTPs.
- In the embodiment when the nucleotide and/or nucleotide analog that is included in the reaction mixture is an NTP, the NTP may be present in a higher concentration than all three of the other NTPs included in the reaction mixture. The other three NTPs may be in an equimolar concentration to one another. Alternatively one or more of the three other NTPs may be in a different concentration than one or more of the other NTPs.

- In addition to the ionizable amino lipid disclosed herein, e.g., compound of formula (I), the lipid composition of the pharmaceutical compositions disclosed herein can comprise additional components such as phospholipids, structural lipids, PEG-lipids, and any combination thereof.
- b. Phospholipids
- The lipid composition of the pharmaceutical composition disclosed herein can comprise one or more phospholipids, for example, one or more saturated or (poly)unsaturated phospholipids or a combination thereof. In general, phospholipids comprise a phospholipid moiety and one or more fatty acid moieties.
- A phospholipid moiety can be selected, for example, from the non-limiting group consisting of phosphatidyl choline, phosphatidyl ethanolamine, phosphatidyl glycerol, phosphatidyl serine, phosphatidic acid, 2-lysophosphatidyl choline, and a sphingomyelin.
- A fatty acid moiety can be selected, for example, from the non-limiting group consisting of lauric acid, myristic acid, myristoleic acid, palmitic acid, palmitoleic acid, stearic acid, oleic acid, linoleic acid, alpha-linolenic acid, erucic acid, phytanoic acid, arachidic acid, arachidonic acid, eicosapentaenoic acid, behenic acid, docosapentaenoic acid, and docosahexaenoic acid.
- Particular phospholipids can facilitate fusion to a membrane. For example, a cationic phospholipid can interact with one or more negatively charged phospholipids of a membrane (e.g., a cellular or intracellular membrane). Fusion of a phospholipid to a membrane can allow one or more elements (e.g., a therapeutic agent) of a lipid-containing composition (e.g., LNPs) to pass through the membrane permitting, e.g., delivery of the one or more elements to a target tissue.
- Non-natural phospholipid species including natural species with modifications and substitutions including branching, oxidation, cyclization, and alkynes are also contemplated. For example, a phospholipid can be functionalized with or cross-linked to one or more alkynes (e.g., an alkenyl group in which one or more double bonds is replaced with a triple bond). Under appropriate reaction conditions, an alkyne group can undergo a copper-catalyzed cycloaddition upon exposure to an azide. Such reactions can be useful in functionalizing a lipid bilayer of a nanoparticle composition to facilitate membrane permeation or cellular recognition or in conjugating a nanoparticle composition to a useful component such as a targeting or imaging moiety (e.g., a dye).
- Phospholipids include, but are not limited to, glycerophospholipids such as phosphatidylcholines, phosphatidylethanolamines, phosphatidylserines, phosphatidylinositols, phosphatidy glycerols, and phosphatidic acids. Phospholipids also include phosphosphingolipid, such as sphingomyelin.

- As generally defined herein, the term “lipid” refers to a small molecule that has hydrophobic or amphiphilic properties. Lipids may be naturally occurring or synthetic.
- Examples of classes of lipids include, but are not limited to, fats, waxes, sterol-containing metabolites, vitamins, fatty acids, glycerolipids, glycerophospholipids, sphingolipids, saccharolipids, and polyketides, and prenol lipids. In some instances, the amphiphilic properties of some lipids leads them to form liposomes, vesicles, or membranes in aqueous media.
- In some embodiments, a lipid nanoparticle (LNP) may comprise an ionizable lipid. As used herein, the term “ionizable lipid” has its ordinary meaning in the art and may refer to a lipid comprising one or more charged moieties. In some embodiments, an ionizable lipid may be positively charged or negatively charged. An ionizable lipid may be positively charged, in which case it can be referred to as “cationic lipid”. In certain embodiments, an ionizable lipid molecule may comprise an amine group, and can be referred to as an ionizable amino lipids. As used herein, a “charged moiety” is a chemical moiety that carries a formal electronic charge, e.g., monovalent (+1, or −1), divalent (+2, or −2), trivalent (+3, or −3), etc. The charged moiety may be anionic (i.e., negatively charged) or cationic (i.e., positively charged). Examples of positively-charged moieties include amine groups (e.g., primary, secondary, and/or tertiary amines), ammonium groups, pyridinium group, guanidine groups, and imidizolium groups. In a particular embodiment, the charged moieties comprise amine groups. Examples of negatively-charged groups or precursors thereof, include carboxylate groups, sulfonate groups, sulfate groups, phosphonate groups, phosphate groups, hydroxyl groups, and the like. The charge of the charged moiety may vary, in some cases, with the environmental conditions, for example, changes in pH may alter the charge of the moiety, and/or cause the moiety to become charged or uncharged. In general, the charge density of the molecule may be selected as desired.
- It should be understood that the terms “charged” or “charged moiety” does not refer to a “partial negative charge” or “partial positive charge” on a molecule. The terms “partial negative charge” and “partial positive charge” are given its ordinary meaning in the art. A “partial negative charge” may result when a functional group comprises a bond that becomes polarized such that electron density is pulled toward one atom of the bond, creating a partial negative charge on the atom. Those of ordinary skill in the art will, in general, recognize bonds that can become polarized in this way.
- In some embodiments, the ionizable lipid is an ionizable amino lipid, sometimes referred to in the art as an “ionizable cationic lipid”. In one embodiment, the ionizable amino lipid may have a positively charged hydrophilic head and a hydrophobic tail that are connected via a linker structure.
- In addition to these, an ionizable lipid may also be a lipid including a cyclic amine group.
- In one embodiment, the ionizable lipid may be selected from, but not limited to, a ionizable lipid described in International Publication Nos. WO2013086354 and WO2013116126; the contents of each of which are incorporated herein by reference in their entirety.
- In yet another embodiment, the ionizable lipid may be selected from, but not limited to, formula CLI-CLXXXXII of U.S. Pat. No. 7,404,969; each of which is incorporated herein by reference in their entirety.
- In one embodiment, the lipid may be a cleavable lipid such as those described in International Publication No. WO2012170889, incorporated herein by reference in its entirety. In one embodiment, the lipid may be synthesized by methods known in the art and/or as described in International Publication Nos.

In some embodiments, the polydispersity index of a nanoparticle composition disclosed herein can be from about 0.10 to about 0.20.
- The zeta potential of a nanoparticle composition can be used to indicate the electrokinetic potential of the composition. For example, the zeta potential can describe the surface charge of a nanoparticle composition.

- The term “encapsulation efficiency” of a polynucleotide describes the amount of the polynucleotide that is encapsulated by or otherwise associated with a nanoparticle composition after preparation, relative to the initial amount provided. As used herein, “encapsulation” can refer to complete, substantial, or partial enclosure, confinement, surrounding, or encasement.
- Encapsulation efficiency is desirably high (e.g., close to 100%). The encapsulation efficiency can be measured, for example, by comparing the amount of the polynucleotide in a solution containing the nanoparticle composition before and after breaking up the nanoparticle composition with one or more organic solvents or detergents.
- Fluorescence can be used to measure the amount of free polynucleotide in a solution. For the nanoparticle compositions described herein, the encapsulation efficiency of a polynucleotide can be at least 50%, for example 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100%. In some embodiments, the encapsulation efficiency can be at least 80%. In certain embodiments, the encapsulation efficiency can be at least 90%.
- The amount of a polynucleotide present in a pharmaceutical composition disclosed herein can depend on multiple factors such as the size of the polynucleotide, desired target and/or application, or other properties of the nanoparticle composition as well as on the properties of the polynucleotide.
- For example, the amount of an mRNA useful in a nanoparticle composition can depend on the size (expressed as length, or molecular mass), sequence, and other characteristics of the mRNA. The relative amounts of a polynucleotide in a nanoparticle composition can also vary.
- The relative amounts of the lipid composition and the polynucleotide present in a lipid nanoparticle composition of the present disclosure can be optimized according to considerations of efficacy and tolerability. For compositions including an mRNA as a polynucleotide, the N:P ratio can serve as a useful metric.
- As the N:P ratio of a nanoparticle composition controls both expression and tolerability, nanoparticle compositions with low N:P ratios and strong expression are desirable. N:P ratios vary according to the ratio of lipids to RNA in a nanoparticle composition.
- In general, a lower N:P ratio is preferred. The one or more RNA, lipids, and amounts thereof can be selected to provide an N:P ratio from about 2:1 to about 30:1, such as 2:1, 3:1, 4:1, 5:1, 6:1, 7:1, 8:1, 9:1, 10:1, 12:1, 14:1, 16:1, 18:1, 20:1, 22:1, 24:1, 26:1, 28:1, or 30:1. In certain embodiments, the N:P ratio can be from about 2:1 to about 8:1. In other embodiments, the N:P ratio is from about 5:1 to about 8:1. In certain embodiments, the N:P ratio is between 5:1 and 6:1. In one specific aspect, the N:P ratio is about is about 5.67:1.
- In addition to providing nanoparticle compositions, the present disclosure also provides methods of producing lipid nanoparticles comprising encapsulating a polynucleotide. Such method comprises using any of the pharmaceutical compositions disclosed herein and producing lipid nanoparticles in accordance with methods of production of lipid nanoparticles known in the art.

- Applications Related to Nanoparticles
- It has been discovered that the immunomodulatory therapeutic compositions described herein are superior to current compositions in several ways. First, the lipid nanoparticle (LNP) delivery is superior to other formulations including liposome or protamine based approaches described in the literature and no additional adjuvants are to be necessary. The use of LNPs enables the effective delivery of chemically modified or unmodified mRNA compositions. Both modified and unmodified LNP formulated mRNA compositions are superior to conventional compositions by a significant degree. In some embodiments the immunomodulatory therapeutic compositions of the invention are superior to conventional compositions by a factor of at least 10 fold, 20 fold, 40 fold, 50 fold, 100 fold, 500 fold or 1,000 fold.
- Although attempts have been made to produce functional RNA vaccines, including mRNA vaccines and self-replicating RNA vaccines, the therapeutic efficacy of these RNA vaccines have not yet been fully established. Quite surprisingly, the inventors have discovered, according to aspects of the invention, a class of formulations for delivering immunomodulatory therapeutic compositions in vivo that results in significantly enhanced, and in many respects synergistic, immune responses including enhanced antigen generation and functional antibody production with neutralization capability. These results can be achieved even when significantly lower doses of the mRNA are administered in comparison with mRNA doses used in other classes of lipid based formulations. The formulations of the invention have demonstrated significant unexpected in vivo immune responses sufficient to establish the efficacy of functional mRNA compositions as immunomodulatory therapeutic agents. Additionally, self-replicating RNA vaccines rely on viral replication pathways to deliver enough RNA to a cell to produce an immunogenic response. The formulations of the invention do not require viral replication to produce enough protein to result in a strong immune response. Thus, the mRNA of the invention are not self-replicating RNA and do not include components necessary for viral replication.
- The invention involves, in some aspects, the surprising finding that lipid nanoparticle (LNP) formulations significantly enhance the effectiveness of mRNA compositions, including chemically modified and unmodified mRNA immunomodulatory therapeutic compositions. The efficacy of mRNA containing immunomodulatory therapeutic compositions formulated in LNP was examined in vivo using several distinct tumor antigens. In addition to providing an enhanced immune response, the formulations of the invention generate a more rapid immune response with fewer doses of antigen than other compositions tested. The mRNA-LNP formulations of the invention also produce quantitatively and qualitatively better immune responses than compositions formulated in a different carriers. Additionally, the mRNA-LNP formulations of the invention are superior to other compositions even when the dose of mRNA is lower than other compositions.
- The LNP used in the studies described herein has been used previously to deliver siRNA in various animal models as well as in humans. In view of the observations made in association with the siRNA delivery of LNP formulations, the fact that LNP is useful in cancer immunomodulatory therapeutic compositions is quite surprising. It has been observed that therapeutic delivery of siRNA formulated in LNP causes an undesirable inflammatory response associated with a transient IgM response, typically leading to a reduction in antigen production and a compromised immune response. In contrast to the findings observed with siRNA, the LNP-mRNA formulations of the invention are demonstrated herein to generate enhanced IgG levels, sufficient for prophylactic and therapeutic methods rather than transient IgM responses.

A method of administration may be selected to target delivery (e.g., to specifically deliver) to a specific region or system of a body. For example, an administration may be parenteral (e.g., subcutaneous, intracutaneous, intravenous, intraperitoneal, intramuscular, intraarticular, intraarterial, intrasynovial, intrasternal, intrathecal, intralesional, or intracranial injection, as well as any suitable infusion technique), oral, trans- or intra-dermal, interdermal, rectal, intravaginal, topical (e.g. by powders, ointments, creams, gels, lotions, and/or drops), mucosal, nasal, buccal, enteral, vitreal, intratumoral, sublingual, intranasal; by intratracheal instillation, bronchial instillation, and/or inhalation; as an oral spray and/or powder, nasal spray, and/or aerosol, and/or through a portal vein catheter.
- Approximately, about: As used herein, the terms “approximately” or “about,” as applied to one or more values of interest, refers to a value that is similar to a stated reference value. In certain embodiments, the term “approximately” or “about” refers to a range of values that fall within 25%, 20%, 19%, 18%, 17%, 16%, 15%, 14%, 13%, 12%, 11%, 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1%, or less in either direction (greater than or less than) of the stated reference value unless otherwise stated or otherwise evident from the context (except where such number would exceed 100% of a possible value).
- Cancer: As used herein, “cancer” is a condition involving abnormal and/or unregulated cell growth. The term cancer encompasses benign and malignant cancers. Exemplary non-limiting cancers include adrenal cortical cancer, advanced cancer, anal cancer, aplastic anemia, bileduct cancer, bladder cancer, bone cancer, bone metastasis, brain tumors, brain cancer, breast cancer, childhood cancer, cancer of unknown primary origin, Castleman disease, cervical cancer, colorectal cancer, endometrial cancer, esophagus cancer, Ewing family of tumors, eye cancer, gallbladder cancer, gastrointestinal carcinoid tumors, gastrointestinal stromal tumors, gestational trophoblastic disease, Hodgkin disease, Kaposi sarcoma, renal cell carcinoma, laryngeal and hypopharyngeal cancer, acute lymphocytic leukemia, acute myeloid leukemia, chronic lymphocytic leukemia, chronic myeloid leukemia, chronic myelomonocytic leukemia, myelodysplastic syndrome (including refractory anemias and refractory cytopenias), myeloproliferative neoplasms or diseases (including polycythemia vera, essential thrombocytosis and primary myelofibrosis), liver cancer (e.g., hepatocellular carcinoma), non-small cell lung cancer, small cell lung cancer, lung carcinoid tumor, lymphoma of the skin, malignant mesothelioma, multiple myeloma, myelodysplasia syndrome, nasal cavity and paranasal sinus cancer, nasopharyngeal cancer, neuroblastoma, non-Hodgkin lymphoma, oral cavity and oropharyngeal cancer, osteosarcoma, ovarian cancer, pancreatic cancer, penile cancer, pituitary tumors, prostate cancer, retinoblastoma, rhabdomyosarcoma, salivary gland cancer, sarcoma in adult soft tissue, basal and squamous cell skin cancer, melanoma, small intestine cancer, stomach cancer, testicular cancer, throat cancer, thymus cancer, thyroid cancer, uterine sarcoma, vaginal cancer, vulvar cancer, Waldenstrom macroglobulinemia, Wilms tumor and secondary cancers caused by cancer treatment. In particular embodiments, the cancer is liver cancer (e.g., hepatocellular carcinoma) or colorectal cancer. In other embodiments, the cancer is a blood-based cancer or a hematopoetic cancer.
- Cleavable Linker: As used herein, the term “cleavable linker” refers to a linker, typically a peptide linker (e.g., about 5-30 amino acids in length, typically about 10-20 amino acids in length) that can be incorporated into multicistronic mRNA constructs such that equimolar levels of multiple genes can be produced from the same mRNA. Non-limiting examples of cleavable linkers include the 2A family of peptides, including F2A, P2A, T2A and E2A, first discovered in picornaviruses, that when incorporated into an mRNA construct (e.g., between two polypeptide domains) function by making the ribosome skip the synthesis of a peptide bond at C-terminus of the 2A element, thereby leading to separation between the end of the 2A sequence and the next peptide downstream.
- Conjugated: As used herein, the term “conjugated,” when used with respect to two or more moieties, means that the moieties are physically associated or connected with one another, either directly or via one or more additional moieties that serves as a linking agent, to form a structure that is sufficiently stable so that the moieties remain physically associated under the conditions in which the structure is used, e.g., physiological conditions. In some embodiments, two or more moieties may be conjugated by direct covalent chemical bonding. In other embodiments, two or more moieties may be conjugated by ionic bonding or hydrogen bonding.
- Contacting: As used herein, the term “contacting” means establishing a physical connection between two or more entities. For example, contacting a cell with an mRNA or a lipid nanoparticle composition means that the cell and mRNA or lipid nanoparticle are made to share a physical connection. Methods of contacting cells with external entities both in vivo, in vitro, and ex vivo are well known in the biological arts. In exemplary embodiments of the disclosure, the step of contacting a mammalian cell with a composition (e.g., an isolated mRNA, nanoparticle, or pharmaceutical composition of the disclosure) is performed in vivo. For example, contacting a lipid nanoparticle composition and a cell (for example, a mammalian cell) which may be disposed within an organism (e.g., a mammal) may be performed by any suitable administration route (e.g., parenteral administration to the organism, including intravenous, intramuscular, intradermal, and subcutaneous administration). For a cell present in vitro, a composition (e.g., a lipid nanoparticle or an isolated mRNA) and a cell may be contacted, for example, by adding the composition to the culture medium of the cell and may involve or result in transfection. Moreover, more than one cell may be contacted by a nanoparticle composition.
- Encapsulate: As used herein, the term “encapsulate” means to enclose, surround, or encase. In some embodiments, a compound, polynucleotide (e.g., an mRNA), or other composition may be fully encapsulated, partially encapsulated, or substantially encapsulated. For example, in some embodiments, an mRNA of the disclosure may be encapsulated in a lipid nanoparticle, e.g., a liposome.
- Effective amount: As used herein, the term “effective amount” of an agent is that amount sufficient to effect beneficial or desired results, for example, clinical results, and, as such, an “effective amount” depends upon the context in which it is being applied. For example, in the context of administering an agent that treats cancer, an effective amount of an agent is, for example, an amount sufficient to achieve treatment, as defined herein, of cancer, as compared to the response obtained without administration of the agent. In some embodiments, a therapeutically effective amount is an amount of an agent to be delivered (e.g., nucleic acid, drug, therapeutic agent, diagnostic agent or prophylactic agent) that is sufficient, when administered to a subject suffering from or susceptible to an infection, disease, disorder, and/or condition, to treat, improve symptoms of, diagnose, prevent, and/or delay the onset of the infection, disease, disorder, and/or condition.
- Expression: As used herein, “expression” of a nucleic acid sequence refers to one or more of the following events: (1) production of an RNA template from a DNA sequence (e.g., by transcription); (2) processing of an RNA transcript (e.g., by splicing, editing, 5′ cap formation, and/or 3′ end processing); (3) translation of an RNA into a polypeptide or protein; and (4) post-translational modification of a polypeptide or protein.
- Identity: As used herein, the term “identity” refers to the overall relatedness between polymeric molecules, e.g., between polynucleotide molecules (e.g., DNA molecules and/or RNA molecules) and/or between polypeptide molecules. Calculation of the percent identity of two polynucleotide sequences, for example, can be performed by aligning the two sequences for optimal comparison purposes (e.g., gaps can be introduced in one or both of a first and a second nucleic acid sequences for optimal alignment and non-identical sequences can be disregarded for comparison purposes). In certain embodiments, the length of a sequence aligned for comparison purposes is at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, or 100% of the length of the reference sequence. The nucleotides at corresponding nucleotide positions are then compared. When a position in the first sequence is occupied by the same nucleotide as the corresponding position in the second sequence, then the molecules are identical at that position. The percent identity between the two sequences is a function of the number of identical positions shared by the sequences, taking into account the number of gaps, and the length of each gap which needs to be introduced for optimal alignment of the two sequences. The comparison of sequences and determination of percent identity between two sequences can be accomplished using a mathematical algorithm. For example, the percent identity between two nucleotide sequences can be determined using methods such as those described in Computational Molecular Biology, Lesk, A. M., ed., Oxford University Press, New York, 1988; Biocomputing: Informatics and Genome Projects, Smith, D. W., ed., Academic Press, New York, 1993; Sequence Analysis in Molecular Biology, von Heinje, G., Academic Press, 1987; Computer Analysis of Sequence Data, Part I, Griffin, A. M., and Griffin, H. G., eds., Humana Press, New Jersey, 1994; and Sequence Analysis Primer, Gribskov, M. and Devereux, J., eds., M Stockton Press, New York, 1991; each of which is incorporated herein by reference. For example, the percent identity between two nucleotide sequences can be determined using the algorithm of Meyers and Miller (CABIOS, 1989, 4:11-17), which has been incorporated into the ALIGN program (version 2.0) using a PAM120 weight residue table, a gap length penalty of 12 and a gap penalty of 4. The percent identity between two nucleotide sequences can, alternatively, be determined using the GAP program in the GCG software package using an NWSgapdna.CMP matrix. Methods commonly employed to determine percent identity between sequences include, but are not limited to those disclosed in Carillo, H., and Lipman, D., SIAM J Applied Math., 48:1073 (1988); incorporated herein by reference. Techniques for determining identity are codified in publicly available computer programs. Exemplary computer software to determine homology between two sequences include, but are not limited to, GCG program package, Devereux et al., Nucleic Acids Research, 12(1): 387,1984, BLASTP, BLASTN, and FASTA, Altschul, S. F. et al., J. Molec. Biol., 215, 403, 1990.
- Fragment: A “fragment,” as used herein, refers to a portion. For example, fragments of proteins may include polypeptides obtained by digesting full-length protein isolated from cultured cells or obtained through recombinant DNA techniques.
- GC-rich: As used herein, the term “GC-rich” refers to the nucleobase composition of a polynucleotide (e.g., mRNA), or any portion thereof (e.g., an RNA element), comprising guanine (G) and/or cytosine (C) nucleobases, or derivatives or analogs thereof, wherein the GC-content is greater than about 50%. The term “GC-rich” refers to all, or to a portion, of a polynucleotide, including, but not limited to, a gene, a non-coding region, a 5′ UTR, a 3′ UTR, an open reading frame, an RNA element, a sequence motif, or any discrete sequence, fragment, or segment thereof which comprises about 50% GC-content. In some embodiments of the disclosure, GC-rich polynucleotides, or any portions thereof, are exclusively comprised of guanine (G) and/or cytosine (C) nucleobases.
- GC-content: As used herein, the term “GC-content” refers to the percentage of nucleobases in a polynucleotide (e.g., mRNA), or a portion thereof (e.g., an RNA element), that are either guanine (G) and cytosine (C) nucleobases, or derivatives or analogs thereof, (from a total number of possible nucleobases, including adenine (A) and thymine (T) or uracil (U), and derivatives or analogs thereof, in DNA and in RNA). The term “GC-content” refers to all, or to a portion, of a polynucleotide, including, but not limited to, a gene, a non-coding region, a 5′ or 3′ UTR, an open reading frame, an RNA element, a sequence motif, or any discrete sequence, fragment, or segment thereof.
- Genetic Adjuvant: A “genetic adjuvant”, as used herein, refers to an mRNA construct (e.g., an mmRNA construct) that enhances the immune response to a vaccine, for example by stimulating cytokine production and/or by stimulating the production of antigen-specific effector cells (e.g., CD8 T cells). A genetic adjuvant mRNA construct can, for example, encode a polypeptide that stimulates Type I interferon (e.g., activates Type I interferon pathway signaling) or that promotes dendritic cell development or activity.
- Heterologous: As used herein, “heterologous” indicates that a sequence (e.g., an amino acid sequence or the polynucleotide that encodes an amino acid sequence) is not normally present in a given polypeptide or polynucleotide. For example, an amino acid sequence that corresponds to a domain or motif of one protein may be heterologous to a second protein.
- Hydrophobic amino acid: As used herein, a “hydrophobic amino acid” is an amino acid having an uncharged, nonpolar side chain. Examples of naturally occurring hydrophobic amino acids are alanine (Ala), valine (Val), leucine (Leu), isoleucine (Ile), proline (Pro), phenylalanine (Phe), methionine (Met), and tryptophan (Trp).
- Immune Potentiator: An “immune potentiator”, as used herein, refers to an mRNA construct (e.g., an mmRNA construct) that enhances an immune response, e.g., to an antigen of interest (either an endogenous antigen in a subject to which the immune potentiator is administered or to an exogenous antigen that is coadministered with the immune potentiator), for example by stimulating T cell, B cell or dendritic cell responses, including but not limited to cytokine production, stimulating antibody production or stimulating the production of antigen-specific immune cells (e.g., CD8+ T cells or CD4+ T cells).
- Initiation Codon: As used herein, the term “initiation codon”, used interchangeably with the term “start codon”, refers to the first codon of an open reading frame that is translated by the ribosome and is comprised of a triplet of linked adenine-uracil-guanine nucleobases. The initiation codon is depicted by the first letter codes of adenine (A), uracil (U), and guanine (G) and is often written simply as “AUG”. Although natural mRNAs may use codons other than AUG as the initiation codon, which are referred to herein as “alternative initiation codons”, the initiation codons of polynucleotides described herein use the AUG codon. During the process of translation initiation, the sequence comprising the initiation codon is recognized via complementary base-pairing to the anticodon of an initiator tRNA (Met-tRNAi Met) bound by the ribosome. Open reading frames may contain more than one AUG initiation codon, which are referred to herein as “alternate initiation codons”.
- The initiation codon plays a critical role in translation initiation. The initiation codon is the first codon of an open reading frame that is translated by the ribosome. Typically, the initiation codon comprises the nucleotide triplet AUG, however, in some instances translation initiation can occur at other codons comprised of distinct nucleotides. The initiation of translation in eukaryotes is a multistep biochemical process that involves numerous protein-protein, protein-RNA, and RNA-RNA interactions between messenger RNA molecules (mRNAs), the 40S ribosomal subunit, other components of the translation machinery (e.g., eukaryotic initiation factors; eIFs). The current model of mRNA translation initiation postulates that the pre-initiation complex (alternatively “43S pre-initiation complex”; abbreviated as “PIC”) translocates from the site of recruitment on the mRNA (typically the 5′ cap) to the initiation codon by scanning nucleotides in a 5′ to 3′ direction until the first AUG codon that resides within a specific translation-promotive nucleotide context (the Kozak sequence) is encountered (Kozak (1989) J Cell Biol 108:229-241). Scanning by the PIC ends upon complementary base-pairing between nucleotides comprising the anticodon of the initiator Met-tRNAi Met transfer RNA and nucleotides comprising the initiation codon of the mRNA. Productive base-pairing between the AUG codon and the Met-tRNAi Met anticodon elicits a series of structural and biochemical events that culminate in the joining of the large 60S ribosomal subunit to the PIC to form an active ribosome that is competent for translation elongation.
- Insertion: As used herein, an “insertion” or an “addition” refers to a change in an amino acid or nucleotide sequence resulting in the addition of one or more amino acid residues or nucleotides, respectively, to a molecule as compared to a reference sequence, for example, the sequence found in a naturally-occurring molecule. In some embodiments, an insertion may be a replacement.
- Insertion Site: As used herein, an “insertion site” is a position or region of a scaffold polypeptide that is amenable to insertion of an amino acid sequence of a heterologous polypeptide. It is to be understood that an insertion site also may refer to the position or region of the polynucleotide that encodes the polypeptide (e.g., a codon of a polynucleotide that codes for a given amino acid in the scaffold polypeptide). In some embodiments, insertion of an amino acid sequence of a heterologous polypeptide into a scaffold polypeptide has little to no effect on the stability (e.g., conformational stability), expression level, or overall secondary structure of the scaffold polypeptide.
- Isolated: As used herein, the term “isolated” refers to a substance or entity that has been separated from at least some of the components with which it was associated (whether in nature or in an experimental setting). Isolated substances may have varying levels of purity in reference to the substances from which they have been associated. Isolated substances and/or entities may be separated from at least about 10%, about 20%, about 30%, about 40%, about 50%, about 60%, about 70%, about 80%, about 90%, or more of the other components with which they were initially associated. In some embodiments, isolated agents are more than about 80%, about 85%, about 90%, about 91%, about 92%, about 93%, about 94%, about 95%, about 96%, about 97%, about 98%, about 99%, or more than about 99% pure. As used herein, a substance is “pure” if it is substantially free of other components.
- Kozak Sequence: The term “Kozak sequence” (also referred to as “Kozak consensus sequence”) refers to a translation initiation enhancer element to enhance expression of a gene or open reading frame, and which in eukaryotes, is located in the 5′ UTR. The Kozak consensus sequence was originally defined as the sequence GCCRCC, where R=a purine, following an analysis of the effects of single mutations surrounding the initiation codon (AUG) on translation of the preproinsulin gene (Kozak (1986) Cell 44:283-292). Polynucleotides disclosed herein comprise a Kozak consensus sequence, or a derivative or modification thereof. (Examples of translational enhancer compositions and methods of use thereof, see U.S. Pat. No. 5,807,707 to Andrews et al., incorporated herein by reference in its entirety; U.S. Pat. No. 5,723,332 to Chernajovsky, incorporated herein by reference in its entirety; U.S. Pat. No. 5,891,665 to Wilson, incorporated herein by reference in its entirety.)
- Leaky scanning: A phenomenon known as “leaky scanning” can occur whereby the PIC bypasses the initiation codon and instead continues scanning downstream until an alternate or alternative initiation codon is recognized. Depending on the frequency of occurrence, the bypass of the initiation codon by the PIC can result in a decrease in translation efficiency. Furthermore, translation from this downstream AUG codon can occur, which will result in the production of an undesired, aberrant translation product that may not be capable of eliciting the desired therapeutic response. In some cases, the aberrant translation product may in fact cause a deleterious response (Kracht et al., (2017) Nat Med 23(4):501-507).

- Modified: As used herein “modified” or “modification” refers to a changed state or a change in composition or structure of a polynucleotide (e.g., mRNA). Polynucleotides may be modified in various ways including chemically, structurally, and/or functionally. For example, polynucleotides may be structurally modified by the incorporation of one or more RNA elements, wherein the RNA element comprises a sequence and/or an RNA secondary structure(s) that provides one or more functions (e.g., translational regulatory activity). Accordingly, polynucleotides of the disclosure may be comprised of one or more modifications (e.g., may include one or more chemical, structural, or functional modifications, including any combination thereof).

In the content of the present disclosure, the terms “uridine-modified sequence” and “uracil-modified sequence” are considered equivalent and interchangeable.
- A “high uridine codon” is defined as a codon comprising two or three uridines, a “low uridine codon” is defined as a codon comprising one uridine, and a “no uridine codon” is a codon without any uridines. In some embodiments, a uridine-modified sequence comprises substitutions of high uridine codons with low uridine codons, substitutions of high uridine codons with no uridine codons, substitutions of low uridine codons with high uridine codons, substitutions of low uridine codons with no uridine codons, substitution of no uridine codons with low uridine codons, substitutions of no uridine codons with high uridine codons, and combinations thereof. In some embodiments, a high uridine codon can be replaced with another high uridine codon. In some embodiments, a low uridine codon can be replaced with another low uridine codon. In some embodiments, a no uridine codon can be replaced with another no uridine codon. A uridine-modified sequence can be uridine enriched or uridine rarefied.
- Uridine Enriched: As used herein, the terms “uridine enriched” and grammatical variants refer to the increase in uridine content (expressed in absolute value or as a percentage value) in a sequence optimized nucleic acid (e.g., a synthetic mRNA sequence) with respect to the uridine content of the corresponding candidate nucleic acid sequence. Uridine enrichment can be implemented by substituting codons in the candidate nucleic acid sequence with synonymous codons containing less uridine nucleobases. Uridine enrichment can be global (i.e., relative to the entire length of a candidate nucleic acid sequence) or local (i.e., relative to a subsequence or region of a candidate nucleic acid sequence).
- Uridine Rarefied: As used herein, the terms “uridine rarefied” and grammatical variants refer to a decrease in uridine content (expressed in absolute value or as a percentage value) in an sequence optimized nucleic acid (e.g., a synthetic mRNA sequence) with respect to the uridine content of the corresponding candidate nucleic acid sequence. Uridine rarefication can be implemented by substituting codons in the candidate nucleic acid sequence with synonymous codons containing less uridine nucleobases. Uridine rarefication can be global (i.e., relative to the entire length of a candidate nucleic acid sequence) or local (i.e., relative to a subsequence or region of a candidate nucleic acid sequence).

- In this example, a series of mmRNA constructs that encoded constitutively activated forms of human STING were made and tested for their ability to stimulate interferon-β (IFN-β) production. The human STING protein encoded by the constructs was constitutively activated through introduction of one or more point mutations. The following single or combination point mutations were tested: (i) V155M; (ii) R284T; (iii) V147L/N154S/V155M; and (iv) R284M/V147L/N154S/V155M. These constructs typically also encoded an epitope tag at either the N-terminus or C-terminus to facilitate detection. Different epitope tags were tested (FLAG, Myc, CT, HA, V5). Additionally, all constructs contained a
Cap 15′ Cap (7mG(5′)ppp(5′)NlmpNp), 5′ UTR, 3′ UTR, a poly A tail of 100 nucleotides and were fully modified with 1-methyl-pseudouridine (m1ψ). The ORF amino acid sequences of representative constitutively active human STING constructs without any epitope tag are shown in SEQ ID NOs: 1-10. An exemplary 5′ UTR for use in the constructs is shown in SEQ ID NO: 21. An exemplary 3′ UTR for use in the constructs is shown in SEQ ID NO: 22. An exemplary 3′ UTR comprising miR-122 and miR-142.3p binding sites for use in the constructs is shown in SEQ ID NO: 23. - To determine whether constitutively active STING constructs could stimulate IFN-β production, the constructs were transfected into human TF1a cells. Wild-type (non-constitutively active) human and mouse STING constructs were used as negative controls. Twenty-five thousand cells/well were plated in 96 well plates and the mmRNA constructs (250 ng) were transfected into them using
Lipofectamine 2000. After 24 and 48 hours, supernatants were harvested and IFN-β levels were determined by standard ELISA. The results are shown inFIG. 1 , which demonstrate that the constitutively active STING constructs stimulated IFN-β production, as compared to the wild-type (non-constitutively active) human and mouse STING controls. While all four mutant STING constructs stimulated IFN-β production, the V155M mutant and the R284T mutant showed the highest activity. These results demonstrate the ability of constitutively active STING mRNA constructs to enhance immune responses through stimulation of IFN-β production. - In a second set of experiments, a reporter gene whose transcription was driven by an interferon-sensitive response element (ISRE) was used to test the ability of a panel of constitutively active STING mRNA constructs to activate the ISRE in a STING KO reporter mouse line. The results are shown in
FIG. 2 , which demonstrates that the constitutively active STING constructs stimulated reporter gene expression, thereby indicating that the constructs were capable of activating the interferon-sensitive response element (ISRE). - In this example, a series of mmRNA constructs that encoded constitutively activated forms of IRF3 or IRF7 were made and tested for their ability to activate an interferon-sensitive response element (ISRE). The ORF amino acid sequences of representative constitutively active mouse and human IRF3 constructs, comprising a S396D point mutation, without any epitope tag are shown in SEQ ID NOs: 11-12. The ORF amino acid sequence of a wild-type human IRF7 construct without any epitope tag is shown in SEQ ID NO: 13. The ORF amino acid sequences of representative constitutively active human IRF7 constructs without any epitope tag are shown in SEQ ID NOs: 14-18. The ORF amino acid sequences of representative truncated human IRF7 constructs (inactive “null” mutations) without any epitope tag are shown in SEQ ID NOs: 19-20. These constructs typically also encoded an epitope tag at either the N-terminus or C-terminus to facilitate detection. Different epitope tags were tested (FLAG, Myc, CT, HA, V5). Additionally, all constructs contained a
Cap 1 5′ Cap (7mG(5′)ppp(5′)NlmpNp), 5′ UTR, 3′ UTR, a poly A tail of 100 nucleotides and were fully modified with 1-methyl-pseudouridine (m1ψ). An exemplary 5′ UTR for use in the constructs is shown in SEQ ID NO: 21. An exemplary 3′ UTR for use in the constructs is shown in SEQ ID NO: 22. An exemplary 3′ UTR comprising miR-122 and miR-142.3p binding sites for use in the constructs is shown in SEQ ID NO: 23. - A reporter gene whose transcription was driven by an interferon-sensitive response element (ISRE) was used to test the ability of constitutively active IRF3 and IRF7 mRNA constructs to activate the ISRE. The results are shown in
FIGS. 3A-3B , which demonstrate that the constitutively active IRF3 constructs (FIG. 3A ) and the constitutively active IRF7 constructs (FIG. 3B ) stimulated reporter gene expression, thereby indicating that the constructs were capable of activating the interferon-sensitive response element (ISRE). - In this example, a luciferase reporter gene whose transcription was driven by the NFκB signaling pathway was used to test the ability of constitutively active IKK, cFLIP and RIPK1 mRNA constructs to activate NFκB signaling.
- Constitutively active IKKβ construct comprised the following two point mutations: S177E/S181E. Constitutively active IKKα or IKKβ constructs comprised PEST mutations. The ORF amino acid sequences of constitutively active IKKβ constructs without any epitope tag are shown in SEQ ID NOs: 87-90. The ORF amino acid sequences of constitutively active IKKα or IKKβ constructs comprising a PEST mutation, without any epitope tag, are shown in SEQ ID NOs: 91-98. Constitutively active cFLIP constructs comprised cFLIP-L, cFLIP-S(aa 1-227), cFLIP p22 (aa 1-198), cFLIP p43 (aa 1-376) or cFLIP p12 (aa 377-480). The ORF amino acid sequences of the cFLIP constructs without any epitope tag are shown in SEQ ID NOs: 82-86. Structures of various constitutively active RIPK1 constructs are described further in, for example, Yatim, N. et al. (2015) Science 350:328-334 or Orozco, S. et al. (2014) Cell Death Differ. 21:1511-1521. The ORF amino acid sequences of the constitutively active RIPK1 constructs without any epitope tag are shown in SEQ ID NOs: 99-104. In addition to the open reading frame, all constructs contained a
Cap 15′ Cap (7mG(5′)ppp(5′)NlmpNp), 5′ UTR, 3′ UTR, a poly A tail of 100 nucleotides and were fully modified with 1-methyl-pseudouridine (m1ψ). An exemplary 5′ UTR for use in the constructs is shown in SEQ ID NO: 21. An exemplary 3′ UTR for use in the constructs is shown in SEQ ID NO: 22. An exemplary 3′ UTR comprising miR-122 and miR-142.3p binding sites for use in the constructs is shown in SEQ ID NO: 23. - In a first series of experiments, either the cFLIP or IKKβ constructs (12.5 ng RNA) were transfected into B16F10, MC38 or HEK293 cells, together with the NFκB-luc reporter gene and the Dual Luc Assay was performed 24 hours post-transfection as an indicator of activation of NFκB signaling. The results are shown in
FIG. 4 , which demonstrates that the constitutively active cFLIP and IKKβ constructs stimulated reporter gene expression, thereby indicating that the constructs were capable of activating the NFκB signaling pathway. In a second series of experiments, the RIPK1 constructs were transfected into B16F10 cells, together with the NFκB-luc reporter gene and the Dual Luc Assay was performed 24 hours post-transfection as an indicator of activation of NFκB signaling. The results are shown inFIG. 5 , which demonstrates that the constitutively active RIPK1 constructs stimulated reporter gene expression, thereby indicating that the constructs were capable of activating the NFκB signaling pathway. - In this example, a series of mmRNA constructs that encoded DIABLO were made and tested for their ability to induce cytokine production. These constructs typically also encoded an epitope tag at either the N-terminus or C-terminus to facilitate detection. Different epitope tags were tested (FLAG, Myc, CT, HA, V5). Additionally, all constructs contained a
Cap 15′ Cap (7mG(5′)ppp(5′)NlmpNp), 5′ UTR, 3′ UTR, a poly A tail of 100 nucleotides and were fully modified with 1-methyl-pseudouridine (m1ψ). The ORF amino acid sequences of the DIABLO constructs without any epitope tag are shown in SEQ ID NOs: 106-113. An exemplary 5′ UTR for use in the constructs is shown in SEQ ID NO: 21. An exemplary 3′ UTR for use in the constructs is shown in SEQ ID NO: 22. An exemplary 3′ UTR comprising miR-122 and miR-142.3p binding sites for use in the constructs is shown in SEQ ID NO: 23. - To determine wither the DIABLO constructs could induce cytokine production, the constructs were transfected into SKOV3 cells. Ten thousand cells/well were plated in 96 well plates and the mmRNA constructs were transfected into them using
Lipofectamine 2000. Stimulation of cytokine production by the DIABLO mmRNA constructs in the SKOV3 cells was measured. The results, shown inFIG. 6 for TNF-α and inFIG. 7 for interleukin 6 (IL-6), demonstrate that a number of the DIABLO mmRNA constructs stimulate production of cytokines by the SKOV3 cells. - In this example, the potency and durability of responses to an MC38 mRNA-based cancer vaccine used in combination with STING, IRF3 or IRF7 immune potentiator mRNA constructs were examined. The MC38 murine tumor model has been used to identify immunogenic mutant peptides containing neoepitopes capable of stimulating anti-tumor T cell responses (see e.g., Yadav, M. et al. (2014) Nature 515:572-576). Thus, a cancer vaccination approach that leads to a robust and durable immune response against tumor neoepitopes is highly desirable.
- The MC38 vaccine used in this example was an mRNA construct encoding an ADR concatemer of three 25mer mutant peptides containing tumor neoepitopes derived from Adpgk, Dpagt1, and Reps1 (this vaccine is also referred to herein as ADRvax). The mRNA construct encodes the open reading frame shown in SEQ ID NO: 120, which also includes an N-terminal His-tag for easy detection. Mice were immunized intramuscularly with the ADRvax mRNA vaccine (at a dose of 0.25 mg/kg) on
days - At
day day 21 andday 35 CD8+ spleen cells for IFN-γ are shown inFIG. 8A (day 21) andFIG. 8B (day 31). Similar results were observed for ICS for TNF-α and for CD8+ PBMCs. The results demonstrate that CD8 vaccine responses were greatly enhanced by the STING immune potentiator construct, and moderately enhanced by the IRF3 and IRF7 immune potentiator constructs. An initial improvement in the antigen-specific CD8 response for mice treated with immune potentiators was observed at day 21 (approximately 5% versus 1% for STING treatment vs. control), which continued to improve by day 35 (up to 15% for STING treatment compared to control), thereby demonstrating the durability of the response. - The percentage of CD8b+ cells among the live CD45+ cells was also examined. The results for
day 35 spleen cells and PBMCs are shown inFIG. 9A , which demonstrates that the genetic adjuvants expand the total CD8b+ population. As demonstrated inFIG. 9B , the majority of the CD8+ spleen cells and PBMCs were found to have an “effector memory” CD62LL phenotype. Additional staining experiments demonstrated that the STING and IRF7 immune potentiator construct slightly reduced the % of total Foxp3+ Treg CD4 Tcells (data not shown). Additional staining experiments demonstrated that the immune potentiators did not change the % of CD138+ plasmablasts (data not shown). - A comprehensive survey of Ras mutations in various cancer types has been reported (Prior, I. A. et al. (2012) Cancer Res. 72:2457-2467). This survey demonstrated that the top four most frequent mutations of KRAS in colorectal cancer, pancreatic cancer and non-small cell lung cancer are G12D, G12V, G13D and G12C. A series of mutant KRAS mRNA constructs were prepared that encoded one or more KRAS peptides containing one of these four mutations, for use as KRAS anti-tumor mRNA-based vaccines. Furthermore, to examine the effect of mRNA-based immune potentiators on KRAS vaccine responses, a series of mRNA constructs were prepared that encoded one or more mutant KRAS peptides linked at the N-terminus or the C-terminus to sequence encoding STING as an immune potentiator. Thus, in these KRAS-STING mRNA constructs, the vaccine antigen(s) and the immune potentiator are encoded by the same mRNA construct.
- Mutant KRAS peptide mRNA constructs were prepared that encoded: a 15mer peptide having the G12D, G12V or the G13D mutation (the amino acid sequence of which is shown in SEQ ID NOs: 36-38, respectively); a 25mer peptide having the G12D, G12V or the G13D mutation (SEQ ID NOs: 39-41, respectively); three copies of the 15mer peptide having the G12D, G12V or the G13D mutation (SEQ ID NOs: 42-44, respectively); or three copies of the 25mer peptide having the G12D, G12V or the G13D mutation (SEQ ID NOs: 45-47, respectively). Additional constructs encoded one copy or three copies of a 25mer peptide having a G12C mutation (SEQ ID NOs: 72-73, respectively) or a wild-type 25mer peptide (SEQ ID NO: 74). In certain embodiments, a G12C KRAS mutation may be used in combination with a G12D, G12V or G13D mutation, or combinations thereof. Nucleotide sequences encoding these mutant KRAS peptides are provided in Example 7.
- Mutant KRAS peptide-STING mRNA constructs, having the STING coding sequence at the N-terminus, were prepared that encoded: a 15mer peptide having the G12D, G12V or the G13D mutation (the amino acid sequence of which is shown in SEQ ID NOs: 48-50, respectively); a 25mer peptide having the G12D, G12V or the G13D mutation (SEQ ID NOs: 51-53, respectively); three copies of the 15mer peptide having the G12D, G12V or the G13D mutation (SEQ ID NOs: 54-56, respectively); or three copies of the 25mer peptide having the G12D, G12V or the G13D mutation (SEQ ID NOs: 57-59, respectively). In certain embodiments, a G12C KRAS mutation may be used in combination with a G12D, G12V or G13D mutation, or combinations thereof. Representative nucleotide sequences encoding these KRAS peptide-STING constructs having the STING coding sequence at the N-terminus are shown in SEQ ID NOs: 160 and 162.
- Mutant KRAS peptide-STING mRNA constructs, having the STING coding sequence at the C-terminus, were prepared that encoded: a 15mer peptide having the G12D, G12V or the G13D mutation (the amino acid sequence of which is shown in SEQ ID NOs: 60-62, respectively); a 25mer peptide having the G12D, G12V or the G13D mutation (SEQ ID NOs: 63-65, respectively); three copies of the 15mer peptide having the G12D, G12V or the G13D mutation (SEQ ID NOs: 66-68, respectively); or three copies of the 25mer peptide having the G12D, G12V or the G13D mutation (SEQ ID NOs: 69-70, respectively). In certain embodiments, a G12C KRAS mutation may be used in combination with a G12D, G12V or G13D mutation, or combinations thereof. Representative nucleotide sequences encoding these KRAS peptide-STING constructs having the STING coding sequence at the C-terminus are shown in SEQ ID NOs: 161 and 163.
- These constructs can also encoded an epitope tag at either the N-terminus or C-terminus to facilitate detection. Different epitope tags can be used (e.g., FLAG, Myc, CT, HA, V5). Additionally, all constructs contained a
Cap 15′ Cap (7mG(5′)ppp(5′)NlmpNp), 5′ UTR, 3′ UTR, a poly A tail and were fully modified with 1-methyl-pseudouridine (m1ψ). An exemplary 5′ UTR for use in the constructs is shown in SEQ ID NO: 21. An exemplary 3′ UTR for use in the constructs is shown in SEQ ID NO: 22. An exemplary 3′ UTR comprising miR-122 and miR-142.3p binding sites for use in the constructs is shown in SEQ ID NO: 23. - To test vaccine responses in mice treated either with a KRAS mutant peptide(s) mRNA vaccine construct or with a KRAS mutant peptide(s) vaccine-STING immune potentiator mRNA construct, mice (HLA-A*11:01 or HLA-A*2:01; Taconic) are immunized with a KRAS mutant peptide vaccine mRNA construct (e.g., encoding one of SEQ ID NOs: 36-47) or with a KRAS mutant peptide vaccine-STING immune potentiator mRNA construct (e.g., encoding one of SEQ ID NOs: 48-71). Mice are immunized intramuscularly on
day 1 and day 15 (0.5 mg/kg) and sacrificed atday 22. To test CD8 vaccine responses, CD8+ spleen cells and PBMCs are restimulated ex vivo for 5 hours at 37 degrees C. in the presence of GolgiPlug™ (containing Brefeldin A; BD Biosciences) with either mutant KRAS peptides (G12D, G12V or G13D) or with wild type KRAS peptide (2 μg/ml per peptide). CD8 vaccine responses can then be assessed by intracellular staining (ICS) for IFN-γ and/or TNF-α. Enhanced ICS responses for IFN-γ and/or TNF-α in mice treated with the KRAS mutant peptide vaccine-STING immune potentiator mRNA construct, as compared to treatment with the KRAS mutant peptide vaccine mRNA construct, indicates that the STING immune potentiator enhances KRAS-specific CD8 vaccine responses. - In this example, mutant KRAS peptide mRNA constructs are used in combination with a separate constitutively active STING immune potentiator mRNA construct to enhance immune responses to the mutant KRAS peptides.
- The most frequently mutated oncogene in cancer is KRAS, which is mutated in roughly 30% of epithelial cancers, primarily lung, colorectal and pancreatic cancers (Pylayeva-Gupta Y, et al., Nat Rev Cancer, Vol. 11(11): 761-774, 2011). The 4 most prevalent KRAS mutant antigens in these three malignancies are G12D, G12V, G13D and G12C, which constitute 80-90% of the KRAS mutations (Prior et al. Cancer Res. 2012 May 15; 72(10): 2457-2467; Cox A D et al, Nat Rev Drug Discov, Vol. 13(11): 828-851, 2011). KRAS mutations occur mostly in a couple of “hotspots” and activate the oncogene. Prior research has shown limited ability to raise T cells specific to the oncogenic mutation. However, much of this was done in the context of the most common HLA allele (A2, which occurs in ˜50% of Caucasians). More recently, it has been demonstrated that (a) specific T cells can be generated against point mutations in the context of less common HLA alleles (A11, C8), and (b) growing these cells ex-vivo and transferring them back to the patient has mediated a dramatic tumor response in a patient with lung cancer. (N Engl J Med 2016; 375:2255-2262Dec. 8, 2016DOI: 10.1056/NEJMoa1609279).
- KRAS mutations occur in approximately 40% of colorectal cancers. As shown in Table 5 below, in CRC (colorectal cancer), only 3 mutations (G12V, G12D, and G13D) account for 96% of KRAS mutations in this malignancy. Furthermore, all CRC patients get typed for KRAS mutations as standard of care.

Data representing total number of tumors with each point mutation were collated from COSMIC v52 release. The most frequent mutations for each isoform for each cancer type are reported (see Table 2 of Prior et al.). In addition, secondary KRAS mutations have been identified in EGFR blockade resistant patients. RAS is downstream of EGFR and it has been found to constitute a mechanism of resistance to EGFR blockade therapies. EGFR blockade resistant KRAS mutant tumors can be targeted using compositions and methods disclosed herein. In a few cases, more than one KRAS mutation was identified in the same patient (up to four different mutations co-occur). Diaz et al. report these secondary KRAS mutations after acquisition of EGFR blockade (see Supplementary Table 2), and Misale et al. reports secondary KRAS mutations after EGFR blockade (see
FIG. 3b ) (Diaz et al. The molecular evolution of acquired resistance to targeted EGFR blockade in colorectal cancers, Nature 486: 537 (2012); Misale et al. Emergence of KRAS mutations and acquired resistance to anti-EGFR therapy in colorectal cancer, Nature 486: 532 (2012)). This mutational spectrum appears to be at least somewhat different than primary tumor missense mutants in colorectal cancer. As shown inFIG. 10 , NRAS is also mutated in colorectal cancer, but at a lower frequency than KRAS, based on analysis available in cBioPortal and Prior et al. - In addition to identification of KRAS mutations in colorectal cancer, such mutations have been found in non-small cell lung carcinoma and pancreatic cancer. Table 7 provides the frequencies of four KRAS mutations in these three cancers.

day 1, bleed taken onday 8, mRNA encoding mutated KRAS (alone or in combination with STING) administered onday 15, animal sacrificed onday 22. The test groups are shown in Table 11 as follows: -

The KRAS and STING constructs are administered at a 1:1 ratio. Ex vivo restimulation (2ug/ml per peptide) is tested for 4 hours at 37 degrees Celsius in the presence of GolgiPlug (Brefeldin A). Intracellular cytokine staining (ICS) is tested for KRAS G12D, KRAS G12V, KRAS G13D, KRAS WT, and no peptide.
- mRNA encoding KRAS mutations, alone or in combination with mRNA encoding constitutively active STING, is tested for the ability to generate T cells. Efficacy of mRNA encoding KRAS mutations is compared, for example, to peptide vaccination. The effect of the STING immune potentiator is determined by comparing treatment with the KRAS mutant peptides alone versus in combination with the STING immune potentiator. For example, CD8 vaccine responses can be assessed by intracellular staining (ICS) for IFN-γ and/or TNF-α as described herein. Enhanced ICS responses for IFN-γ and/or TNF-α in mice treated with the KRAS mutant peptide vaccine in combination with the STING immune potentiator mRNA construct, as compared to treatment with the KRAS mutant peptide vaccine mRNA construct alone, indicates that the STING immune potentiator enhances KRAS-specific CD8 vaccine responses.
- In a second study to examine the effect of the STING immune potentiator mRNA construct on immune responses to various different forms of the mutant KRAS peptide antigen mRNA constructs, HLA*A*11:01 Tg mice (Taconic, strain 9660F, n=4) are administered mRNA encoding various different forms of mutated KRAS peptide antigen mRNA constructs in combination with a STING immune potentiator mRNA construct as follows: mRNA encoding mutated KRAS in combination with STING administered on
day 1, bleed taken onday 8, mRNA encoding mutated KRAS in combination with STING administered onday 15, animal sacrificed onday 22. - The types of mutated KRAS constructs tested were as follows: (i) mRNA encoding a single mutant KRAS 25mer peptide antigen containing either the G12D, G12V, G13D or G12C mutation (“singlet”); (ii) mRNA encoding a concatemer of three 25mer peptide antigens (thus creating a 75mer), one of each containing the G12D, G12V and G13D mutations (“KRAS-3MUT”); (iii) mRNA encoding a concatemer of four 25mer peptide antigens (thus creating a 100mer), one of each containing the G12D, G12V, G13D and G12C mutations (“KRAS-4MUT”); or (iv) four separate mRNAs coadministered together, each encoding a single mutant KRAS 25mer peptide antigen containing either the G12D, G12V, G13D or G12C mutation (“Single×4”).
- The amino acid and nucleotide sequences of the G12D 25mer are shown in SEQ ID NOs: 39 and 126, respectively. The amino acid and nucleotide sequences of the G12V 25mer are shown in SEQ ID NOs: 40 and 127, respectively. The amino acid and nucleotide sequences of the G13D 25mer are shown in SEQ ID NOs: 41 and 128, respectively. The amino acid and nucleotide sequences of the G12C 25mer are shown in SEQ ID NOs: 72 and 132 respectively. The amino acid and nucleotide sequences of the KRAS-3MUT 75mer are shown in SEQ ID NOs: 135 and 136, respectively. The amino acid and nucleotide sequences of the KRAS-4MUT 100mer are shown in SEQ ID NOs: 137 and 138, respectively.
- The test groups are shown in Table 12 as follows:

The KRAS and STING constructs are administered at a 5:1 ratio. Ex vivo restimulation (2ug/ml per peptide) is carried out for 5 hours at 37 degrees Celsius in the presence of GolgiPlug (Brefeldin A). Intracellular cytokine staining (ICS) is tested for KRAS G12D, KRAS G12V, KRAS G13D, G12C, KRAS WT, and no peptide.
- The ability of the various mRNAs encoding KRAS mutations in combination with mRNA encoding constitutively active STING to generate T cell responses is tested to allow for comparison of the effect of the STING immune potentiator on the various different KRAS constructs. For example, CD8 vaccine responses can be assessed by intracellular staining (ICS) for IFN-γ and/or TNF-α as described herein.
- In this example, the potency and durability of responses to a human papillomavirus (HPV) E6/E7 mRNA-based vaccine used in combination with STING, IRF3 or IRF7 immune potentiators were examined. A specific immune response to human papillomavirus (HPV) in the cervical microenvironment is known to play a key role in eradicating infection and eliminating mutated cells. However, high-risk HPVs are known to modulate immune cells to create an immunosuppressive microenvironment (see e.g., Prata, T. T. et al. (2015) Immunology 146:113-121). Thus, an HPV vaccination approach that leads to a robust and durable immune response is highly desireable.
- The HPV vaccines used in this example were mRNA constructs encoding either intracellular or soluble forms of
HPV 16 antigens E6 and E7, referred to herein as iE6/E7 and sE6/E7, respectively. To create the soluble format, a signal peptide required for secretion was fused to the N-terminal of the antigen. The sequence of the signal peptide was derived from the Ig kappa chain V-III region HAH. Mice were immunized intramuscularly with either the iE6/E7 or sE6/E7 mRNA vaccine (at a dose of 0.25 mg/kg) ondays - At
day - Representative ICS results for E7-specific responses by
day 21 spleen cells for IFN-γ and TNF-α are shown inFIG. 11A (IFN-γ) andFIG. 11B (TNF-α). Representative ICS results for E6-specific responses byday 21 spleen cells for IFN-γ and TNF-α are shown inFIG. 12A (IFN-γ) andFIG. 12B (TNF-α). The results inFIGS. 11A-11B and 12A-12B demonstrate that CD8 vaccine responses (to both the intracellular and soluble antigen format) were greatly enhanced when the STING, IRF3 or IRF7 immune potentiators were co-formulated with the vaccine, with the E7 epitope being stronger and less variable than the E6 epitope and with the soluble form of antigen being stronger than the intracellular form of antigen. This enhanced CD8 vaccine responses by the immune potentiators was shown to be durable, as evidenced by therepresentative day 21 versusday 53 E7-specific spleen cell IFN-γ ICS data shown inFIGS. 13A and 13B , respectively. Similar results to the spleen cell data were observed for the PBMC experiments (data not shown). - The percentage of CD8b+ cells among the live CD45+ cells was also examined. The results for
day 21 versusday 53 spleen cells are shown inFIGS. 14A and 14B , respectively. The results demonstrate that the immune potentiators (in particular the STING construct) expand the total CD8b+ population onday 21 but notday 53. - The ability of the immune potentiator constructs to enhance the CD8 vaccine response was further confirmed by E7-MHC1-tetramer staining. Representative results for
day 21 versusday 53 spleen cells are shown inFIGS. 15A and 15B , respectively. The E7-MHC-1-tetramer staining results were consistent with the ICS results discussed above, although they were more variable. As demonstrated inFIGS. 16A-16D , the majority of the tetramer positive CD8 cells were found to have an “effector memory” CD62Llo phenotype. Comparison ofday 21 versusday 53 E7-tetramer+ CD8 cells demonstrated that this “effector-memory” CD62Llo phenotype was maintained throughout the study. Additional staining experiments demonstrated that the immune potentiators slightly reduced the % of total Foxp3+ Treg CD4 Tcells (data not shown) and did not change the % of CD138+ plasmablasts (data not shown). - In this example, mice were treated with an HPV vaccine in combination with a STING immune potentiator either prior to, at the same time as, or after challenge with TC1 tumor cells. TC-1 is an HPV16 E7-expressing murine tumor model known in the art (see e.g., Bartkowiak et al. (2015) Proc. Nat. Acad. Sci. USA 112:E5290-5299). The HPV vaccines used in this example were mRNA constructs encoding either intracellular or soluble forms of
HPV 16 antigens E6 and E7, referred to herein as iE6/E7 and sE6/E7, respectively, as described in Example 8. The constitutively active STING immune potentiator used in this example contained a V155M mutation, as described in Example 8. The HPV vaccine construct and the immune potentiator construct were coformulated in MC3 lipid nanoparticles. Certain mice were also treated with an immune checkpoint inhibitor (either anti-CTLA-4 or anti-PD-1). - In a first set of experiments examining the prophylactic activity of the HPV+STING vaccination, C57/B6 mice were treated by intramuscular injection with 0.5 mg/kg of the HPV +STING vaccine (encoding either sE6/E7 or iE6/E7) on either (i) days −7 and −14, or (ii)
days day 1. Certain mice were also treated ondays FIGS. 17A-17C , whereinFIGS. 17A and 17B show data for mice treated on days −14 and −7 with either sE6/E7 (FIG. 17A ) or iE6/E7 (FIG. 17B ) andFIG. 17C shows data for mice treated ondays - In a second set of experiments examining the therapeutic activity of the HPV+STING vaccination, C57/B6 mice were administered 2×105 TC1 cells subcutaneously on
day 1, followed by treatment by intramuscular injection with 0.5 mg/kg of the HPV+STING vaccine (encoding sE6/E7) ondays days FIGS. 18A-18I . The results demonstrate that the mice treated with the HPV+STING vaccine (alone or in combination with immune checkpoint inhibitors) showed tumor regression (FIGS. 18A-18C ), as compared to the control mice treated with the control mRNA construct NTFIX, alone or in combination with an immune checkpoint inhibitor (FIGS. 18D-18F ) or the control mice treated with the sE6/E7 construct in combination with the control DMXAA construct, alone or in combination with an immune checkpoint inhibitor (FIGS. 18G-18I ). Thus, these experiments demonstrate that therapeutic vaccination (i.e., subsequent to tumor challenge) with the HPV vaccine together with the STING immune potentiator is effective in inducing regression of HPV-expressing tumors in vivo. - In this example, studies were performed in animals treated with an antigen of interest in combination with an immune potentiator at different Ag:Immune Potentiator ratios, followed by examination of T cell responses to the antigen, to determine optimal Ag:Immune Potentiator ratios in enhancing the immune response to the antigen of interest.
- In a first set of experiments, mice were treated with an MC38 vaccine encoding an ADR concatemer of three 25mer mutant peptides containing tumor neoepitopes derived from Adpgk, Dpagt1, and Reps1 (this vaccine is also referred to herein as ADRvax), as described in Example 5, in combination with a constitutively active STING immune potentiator construct. The constitutively active STING immune potentiator used in this example contained a V155M mutation, as described in Example 1. The ADRvax and STING constructs were coformulated in a lipid nanoparticle (comprising Compound 25 (Cmp25)) at varying Ag:STING ratios, according to the study design summarized below in Table 13.

days day 21, CD8+ spleen cells from mice in each test group were restimulated ex vivo for 4 hours at 37 degrees C. in the presence of GolgiPlug™ (containing Brefeldin A; BD Biosciences) with either wild-type or mutant MC38 ADR peptides (1 μg/ml per peptide, pooled) and CD8 vaccine responses were assessed by intracellular staining (ICS) for IFN-γ or TNF-α. Representative ICS results for MC38 ADR-specific responses byday 21 CD8+ spleen cells for IFN-γ are shown inFIG. 19 and for TNF-α are shown inFIG. 20 . Additionally, CD8 vaccine responses to each of the three individual epitopes within ADRvax (i.e., peptides Adpk1, Reps1 and Dpagt1) were also assessed by ICS for IFN-γ following stimulation with the individual epitopes. The results are shown inFIG. 21A (for peptide Adpk1),FIG. 21B (for peptide Reps1) andFIG. 21C (for peptide Dpagt1). - The results demonstrate that all Ag:STING ratios tested (ranging from 1:1 to 20:1) showed an adjuvant effect of STING as compared to control. For the ADRvax antigen as a whole, the optimal Ag:STING ratio was found to be 5:1. For the individual peptide epitopes within ADRvax, the optimal Ag:STING ratio for the Adpgk1 peptide was 5:1, whereas the optimal Ag:STING ratio for the Reps1 peptide was 10:1 (the responses to the third peptide, Dpagt1, were very low with or without STING, consistent with it being a non-dominant epitope as was known in the art). STING was also found to increase the total percentage of CD8+ cells among CD45+ T cells, with dose responses observed (data not shown) and was found to increase the total percentage of CD62L cells among CD44hi CD8+ cells (effector/memory subset), with dose responses observed (data not shown). Furthermore, results obtained from PBMC cells were consistent with the spleen cell results (data not shown). Thus, these experiments confirmed the ability of STING to act as an immune potentiator in enhancing immune responses against the ADRvax antigen and, moreover, demonstrated the determination of an optimal Ag:Immune Potentiator ratio for treatment, with ratios other than 1:1 being found to be most optimal (e.g., ratios of 5:1 or 10:1 being more effective than 1:1). The results further indicate that the optimal Ag:Immune Potentiator ratio may differ depending on the particular antigen of interest used.
- In a second set of experiments, non-human primates were treated with an HPV vaccine encoding intracellular E6/E7 (iE6/E7), as described in Example 8, in combination with the constitutively active STING immune potentiator construct at varying Ag:STING ratios (lipid nanoparticles comprising Compound 25), according to the study design summarized below in Table 14:
-
TABLE 14 Ag:STING μg μg Total Ag Group Treatment Ratio μg Ag STING NTFIX n Dose 1 STING only — — 100 — 3 100 μg 2 Ag:STING 1:1 50 50 — 3 Ag:STING 5:1 83.33 16.67 — 4 Ag:STING 10:1 90.9 9.09 5 Ag only — 90 — 10
No clinical findings were observed 24 hours after the first dose (administered intramuscularly), indicating no injection site reactions and that the initial treatment was received safely. After an initial dosing onDay 1, animals have a two week recover period and then are given a second dose atday 14, followed by another two week recovery period. Further safety analysis is determined by clinical pathology (clinical chemistry, hematology and coagulation) atdays - In a third set of experiments, a model concatemeric antigen using known murine epitopes was tested in mice in combination with the constitutively active STING immune potentiator at varying ratios. The concatemeric antigen, referred to herein as CA-132, comprises 20 known murine epitopes thought to be presented on MHC Class I and Class II antigens of the CB6 mouse. These epitopes were sourced from the IEDB.org website, a public database of epitopes sourced from the literature. Class I epitopes are expected to be presented on MHC Class I molecules and trigger a CD8+ response, while Class II epitopes are expected to be presented on MHC Class II molecules and trigger CD4+ T cell responses. The CA-132 antigen construct encodes both Class I and Class II epitopes, allowing for assessment of both CD4 and CD8 T cell responses. Moreover, it is believed that inclusion of Class II epitopes in the concatemeric antigen (thus triggering a CD4 response) helps induce a stronger CD8 T cell response. Thus, the approach to the design of the CA-132 antigen can also be used in the design of other concatemeric antigen constructs.
- The CA-132 antigen construct and STING immune potentiator construct were coformulated in lipid
nanoparticles comprising Compound 25 and administered intramuscularly to CB6 mice at the following dosages: CA-132 alone at 1 g, 3 g or 10 g, STING alone at 3 μg, CA-132+STING at either 3 μg each or 1 μg each (1:1 ratio), CA-132 at 3 μg and STING at 1 μg (Ag:STING ratio of 3:1) or CA-132 at 1 μg and STING at 3 μg (Ag:STING ratio of 1:3). Antigen-specific T cell responses to the Class I epitopes within the CA-132 antigen construct were examined by ELISpot analysis for IFN-γ, the results of which are shown inFIG. 22 . The results demonstrated an increase in IFN-γresponses to the Class I epitopes when formulated with STING. - In a fourth series of experiments, the HPV vaccine model described in Example 8 was used to study the effect of varying ratios of E6/E7 antigen to constitutively active STING immune potentiator. Mice were immunized intramuscularly with the iE6/E7 mRNA vaccine (3 μg or 5 μg) in combination with the V155M constitutively active STING immune potentiator mRNA construct at Ag:STING ratios of 1:1, 5:1, 10:1, 20:1 or 0.4:1. The HPV vaccine construct and the immune potentiator construct were coformulated in MC3 lipid nanoparticles. HPV vaccine or STING in combination with only a control mRNA (NTFIX) were used as controls.
- At
day 21, spleen cells from mice in each test group were restimulated ex vivo for 4 hours at 37 degrees C. in the presence of GolgiPlug™ (containing Brefeldin A; BD Biosciences) with an E7 peptide pool (described in Example 8). CD8 vaccine responses were assessed by intracellular staining (ICS) for IFN-γ. The results are shown inFIG. 23A . The results demonstrate that STING enhanced the antigen-specific T cell responses at all Ag:STING ratios tested. The largest enhancement was observed for the mice treated with the higher dose of antigen (5 μg) at a 1:1 ratio with STING and for the mice treated at an Ag:STING ratio of 0.4:1 (3 μg Ag to 7 μg STING). - The ability of STING to enhance the CD8 vaccine response in the HPV model at various Ag: STING ratios tested was further confirmed by H2-Kb/E7 peptide-tetramer staining. Representative results for
day 21 spleen cells are shown inFIG. 23B . The E7-MHC-1-tetramer staining results were consistent with the ICS results discussed above, although they were more variable. - In summary, these studies confirmed the ability of the STING immune potentiator construct to enhance immune responses to an antigen of interest and demonstrated the determination of optimal Ag:STING ratios for treatment.
- In this example, non-human primates (cynomolgus monkeys) were treated with mRNAs encoding an HPV vaccine in combination with a STING immune potentiator, followed by assessment of antigen-specific T cell and antibody responses. The HPV vaccine construct used in this example is described in Example 8. The constitutively active STING immune potentiator construct used in this example contained a V155M mutation, as described in Example 8. The HPV vaccine construct and the immune potentiator mRNA constructs were coformulated in lipid nanoparticles comprising: Compound 25:Cholesterol:DSPC:PEG-DMG, at ratios of 50:38.5:10:1.5, respectively. Different ratios of STING:Ag were tested. Control animals were treated with mRNAs encoding either the HPV antigens alone or the STING immune potentiator alone.
- Fifteen male cynomolgus monkeys, 2-5 years old and weighing 2-5 kg, were treated according to the study design shown below in Table 15:

day 1 andday 15. A post-dose sample of PBMCs was collected onday 29. No toxicity or other major clinical observations were noted during the study, indicating the mRNA LNPs were well-tolerated. - To examine the ability of the STING immune potentiator to enhance antigen-specific CD8+ T cell responses, intracellular cytokine staining (ICS) for TNFα and IL-2 was conducted. PBMCs were stimulated ex vivo with the HPV16 E6 peptide pool or the HPV16 E7 peptide pool for 6 hours at 37° C. Stimulation with PMA/ionomycin was used as a positive control and stimulation with medium alone was used as a negative control.
- Representative results for ICS for TNFα are shown in
FIGS. 24A-24C , whereinFIG. 24A shows results for ex vivo stimulation with the E6 peptide pool,FIG. 24B shows the results for ex vivo stimulation with the E7 peptide pool andFIG. 24C shows the results for ex vivo stimulation with the medium control. No increase in TNFα+ CD8 T cell frequency was observed between the pre- and post-dose group immunized with antigen alone (Group 1). Immunization with STING treatment alone (Group 2) had a marginal effect on TNFα+ CD8 T cell frequency. In contrast, groups immunized with STING+Ag (Groups Group 5, which was immunized with a “matching” antigen dose of STING:Ag (1:10 ratio), showed a significant increase in antigen-specific TNFα+ CD8 T cells when compared to theGroup 1 andGroup 2 controls. - Representative results for ICS for IL-2 are shown in
FIGS. 25A-25C , whereinFIG. 25A shows results for ex vivo stimulation with the E6 peptide pool,FIG. 25B shows the results for ex vivo stimulation with the E7 peptide pool andFIG. 25C shows the results for ex vivo stimulation with the medium control. A moderate increase in IL-2+ CD8 T cell frequency between the pre- and post-dose was observed in all immunized animals (Groups 1-5). However, the increase in IL-2+ CD8 T cells was most detectable in the groups treated with STING:Ag at ratios of 1:1 and 1:5 (Groups 3 and 4), whereas animals treated with STING:Ag at a 1:10 ratio did not exhibit increased IL-2+ CD8 T cells as compared to controls. The increase in IL-2 is consistent with the known ability of subsets of T cells to secrete IL-2 during active T cell responses. - To examine the effect of STING:Ag treatment in the NHPs on antigen-specific antibody responses, E6-specific and E7-specific ELISAs were performed. Plates were coated with either recombinant E6 (Prospec; #HPV-005 His HPV16 E6) or recombinant E7 (ProteinX; #2003207 His HPV16 E7). A mouse anti-E6 monoclonal antibody from Alpha Diagnostics International (#HPV16E6 1-M) was used as a positive control. A mouse anti-E7 monoclonal antibody from Fisher/Life Technologies (#280006-EA) was used as a positive control. An anti-mouse IgG-HRP antibody from Jackson ImmunoResearch (#715-035-150) was used as the secondary antibody for the positive controls. Anti-monkey IgG-HRP from Abcam (#ab112767) was used as the secondary antibody for the NHP serum.
- Plates were coated with recombinant E6 or E7 (500 ng/well; 100 μl/well) at 4° C. overnight and then blocked with TBS SuperBlock for 1 hour at room temperature. Primary antibody was added (100 μl/well) and incubated for 1 hour at room temperature. Positive control antibodies were serially diluted. NHP serum was diluted 1:5000. After washing, secondary antibody was added (100 μl/well) and incubated for 1 hour at room temperature. Positive control anti-mouse IgG-HRP was diluted 1:5000. For the NHP serums, anti-monkey IgG-HRP was diluted 1:30,000. Color was developed for 5 minutes (anti-E6) or for 10 minutes (anti-E7), then stopped and read at 450 nm.
- Representative results for anti-HPV16 E6 IgG are shown in
FIG. 26 . Representative results for anti-HPV16 E7 IgG are shown inFIG. 27 . The results for both anti-E6 and anti-E7 demonstrate that treatment of the animals with STING:Ag, particularly at ratios of 1:5 and 1:10 led to increased antigen-specific antibody responses. - To further study the antigen-specific IgG response, further ELISA studies were performed using a two-fold dilution series for
day 25 serums. As shown inFIG. 28 , the two-fold dilution series for the animals treated at a 1:10 STING:Ag ratio exhibited a clear enhancement in the levels of anti-HPV16 E6-specific IgG antibodies, as compared to animals treated with the HPV vaccine alone. Calculated titer values from these ELISA studies with theday 25 serum two-fold dilution series for anti-E6 IgG and anti-E7 IgG are shown inFIGS. 29A and 29B , respectively. The calculated titer values, particularly for the anti-E6 specific response, confirm the enhancement by the STING immune potentiator, with the 1:10 STING:Ag ratio showing the greatest enhancement. - Accordingly, the results described herein for the non-human primate study confirm that STING immunopotentiates antigen-specific T cell and antibody responses against an mRNA vaccine antigen in vivo.
- In this example, to examine the effect of the STING immune potentiator mRNA construct on immune responses to various different forms of the mutant KRAS peptide antigen mRNA constructs, HLA*A*11:01 Tg mice (Taconic, strain 9660F, n=3) were administered mRNA encoding various different forms of mutated KRAS peptide antigen mRNA constructs in combination with a STING immune potentiator mRNA construct as follows: mRNA encoding mutated KRAS in combination with STING administered on
days day 21. Mice were aged 6-9 weeks atday 0. mRNA was administered to the animals at a dose of 0.5 mg/kg (10ug per 20-g animal). The KRAS and STING constructs are administered at a 5:1 ratio (Ag:STING). - The types of mutated KRAS constructs tested were as follows: (i) mRNA encoding a single mutant KRAS 25mer peptide antigen containing either the G12D, G12V, G13D or G12C mutation (“monomer”); (ii) mRNA encoding a concatemer of three 25mer peptide antigens (thus creating a 75mer), one of each containing the G12D, G12V and G13D mutations (“KRAS-3MUT concatemer”); (iii) mRNA encoding a concatemer of four 25mer peptide antigens (thus creating a 100mer), one of each containing the G12D, G12V, G13D and G12C mutations (“KRAS-4MUT concatemer”); or (iv) four separate mRNAs coadministered together, each encoding a single mutant KRAS 25mer peptide antigen containing either the G12D, G12V, G13D or G12C mutation (“pooled monomers”). The amino acid and nucleotide sequences of the constructs are as described in Example 7. An A11-viral epitope concatemer antigen was also tested in combination with STING or a control mRNA (NTFIX) (“validated A11 Ag”).
- The test groups are shown in Table 16 as follows:

day 21 spleen cells from the mice were restimulated ex vivo with KRAS monomer peptides (2ug/ml per peptide) for 5 hours at 37 degrees Celsius in the presence of GolgiPlug (Brefeldin A). Intracellular cytokine staining (ICS)(IFN-γ) was performed for KRAS G12D (aa*7/8-16), KRAS G12V (aa*7/8-16), KRAS G13D (aa*7/8-16), G12C (aa*7/8-16), KRAS WT (aa*7/8-16) and no peptide. - The ICS results for KRAS-G12V-specific responses are shown in
FIG. 30 . The ICS results for KRAS-G12D-specific responses are shown inFIG. 31 . These results demonstrate that anti-KRAS-G12V and anti-KRAS-G12D specific CD8+ T cells were detected in mice immunized with the corresponding KRAS-STING vaccine (monomer or concatemer) and restimulated with the cognate peptide. Comparable % IFN-gamma positive CD8+ T cells were seen when the KRAS mutations were administered to the mice as a monomer or as concatemers. The responses observed with G12V were stronger than the responses observed with G12D. In this experiment, anti-KRAS G12C and anti-KRAS G13D responses were not observed (data not shown). - In a second set of experiments to evaluate antigen-specific CD8+ T cell responses to KRAS antigens,
day 21 spleen cells from the mice were co-cultured with HLA*A11-expressing target cells (Cos7-A11 cells) that had been pulsed with the corresponding KRAS peptides (G12V, G12D or WT control), followed by ICS (IFN-γ). The Cos7-A11 co-culture results for KRAS-G12V-specific responses are shown inFIG. 32 . The Cos7-A11 co-culture results for KRAS-G12D-specific responses are shown inFIG. 33 . These results demonstrate that anti-KRAS-G12V and anti-KRAS-G12D specific CD8+ T cell responses were detected in mice immunized with the corresponding KRAS-STING vaccine (monomer or concatemer) and restimulated with the A11+ expressing cell line pulsed with G12V or G12D. Thus, the results in this second set of experiments with respect to detection of antigen-specific CD8+ T cell responses to the KRAS antigens were very similar to the results from the first set of experiments using restimulation with cognate peptides. - Finally, the ability of STING to potentiate antigen-specific response to known A*11-restricted viral epitopes was evaluated using
day 21 spleen cells from the mice immunized with an A11-viral epitope concatemer. Eight viral epitopes (EBV BRLF1, FLU, HIV NEF, EBV, HBV core antigen, HCV, CMV and BCL-2L1) (25 amino acids each) were concatemerized and encoded by mRNA for use as an antigen in combination with STING in the A11-transgenic mice (treatment group 9 in Table 16). The A11-viral epitope concatemer was also co-administered with an NTFIX control mRNA (treatment group 10 in Table 16). Five of the eight epitopes (EBV BRLF1, FLU, HIV NEF, EBV, HBV core antigen) were validated A11 binders with relatively low predicted IC50s; the other three epitopes (HCV, CMV and BCL-2L1) had more moderate predicted affinities for A11 but have not been experimentally validated. The amino acid sequences for the viral epitopes, as well as their IC50s, are shown below in Table 17: -

Day 21 spleen cells were restimulated ex vivo with the individual A*11 viral epitopes, followed by ICS (IFN-γ and TNF-α), to detect antigen-specific CD8+ T cell responses. Antigen-specific CD8+ T cell responses were observed for four out of the eight viral epitopes (EBV, EBV BRLF1, FLU and HIV NEF) and, as shown inFIG. 34 , STING potentiated T cell responses for these four viral epitopes. - A repeat study was performed in HLA*A11 transgenic mice using the KRAS-4MUT concatemer, at either a low dose (10 μg) or a high dose (30 μg), in combination with the STING immune potentiator mRNA at an Ag:STING ratio of 5:1. Significant enhancement of G12V-specific CD8 T cell responses by the STING immune potentiator construct was again observed, with the greatest enhancement being seen at the higher dose of antigen tested (30 μg).
- Accordingly, the results described herein for HLA*A11 transgenic mice demonstrate that STING immunopotentiates antigen-specific T cell anti-KRAS responses, as well as anti-viral responses to other A11-restricted viral antigens, and is able to immunopotentiate responses to vaccine antigens in various formats (monomers and concatemers).
