Description
1. CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of and priority to the PCT Application entitled “NUCLEIC ACID VACCINES FOR MUTANT CORONAVIRUS” filed on July 30, 2021 and designated with the PCT Application Number PCT/CN2021/109704, which is hereby incorporated by reference in its entirety for all purposes.
The present disclosure generally relates to nucleic acid molecules that can be used for the management, prevention, and treatment of coronavirus infection, including infection by mutant strains of the virus. The present disclosure also relates to lipid-containing compositions, including vaccines, of the nucleic acid molecules, and related methods of delivery.
Coronaviruses pose serious health threats to humans and other animals. From 2002 to 2003, severe acute respiratory syndrome coronavirus (SARS-CoV) infected 8,000 people, with a fatality rate of ~9%. Since 2012, Middle East respiratory syndrome coronavirus (MERS-CoV) has infected more than 1, 700 people, with a fatality rate of ~36%. Since 2013, porcine epidemic diarrhea coronavirus (PEDV) has swept throughout the United States, causing an almost 100%fatality rate in piglets and wiping out more than 10%of America’s pig population in less than a year. In March 2020, the World Health Organization (WHO) announced a pandemic caused by the outbreak of Coronavirus Disease 2019 (COVID-19) , which swept into more than 180 countries and killed more than 80,000 people in the first few months of the outbreak. The infectious pathogen responsible for COVID-19 is coronavirus SARS-CoV-2. Subsequently, multiple mutant variants of the SARS-CoV-2 coronavirus emerged, which were different from the version of the virus first detected. For example, one mutated version was detected in southeastern England in September 2020. That variant, now known as B. 1.1.7, quickly became the most common version of the coronavirus in the United Kingdom, accounting for about 60%of new COVID-19 cases in December 2020. Different variants emerged in Brazil, California and other areas. Another variant called B. 1.351, which first appeared in South Africa, was reported to have the ability to re-infect people who have recovered from earlier versions of the coronavirus, and might also be somewhat resistant to some of the coronavirus vaccines designed for the earlier versions of the coronavirus.
In general, COVID-19 patients show symptoms of widespread respiratory, gastrointestinal, and central nervous system diseases in humans and other animals. The pandemic threatened human health and causing economic loss in many countries and regions of the world. Therefore, there exist an urgent need for effective therapeutics, including vaccines for curbing coronavirus infections. The present disclosure meets this need.

6.2 Terminology
Unless described otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of ordinary skill in the art. For purposes of interpreting this specification, the following description of terms will apply and whenever appropriate, terms used in the singular will also include the plural and vice versa. All patents, applications, published applications, and other publications are incorporated by reference in their entirety. In the event that any description of terms set forth conflicts with any document incorporated herein by reference, the description of term set forth below shall control.
As used herein and unless otherwise specified, the term “lipid” refers to a group of organic compounds that include, but are not limited to, esters of fatty acids and are generally characterized by being poorly soluble in water, but soluble in many nonpolar organic solvents. While lipids generally have poor solubility in water, there are certain categories of lipids (e.g., lipids modified by polar groups, e.g., DMG-PEG2000) that have limited aqueous solubility and can dissolve in water under certain conditions. Known types of lipids include biological molecules such as fatty acids, waxes, sterols, fat-soluble vitamins, monoglycerides, diglycerides, triglycerides, and phospholipids. Lipids can be divided into at least three classes: (1) “simple lipids, ” which include fats and oils as well as waxes; (2) “compound lipids, ” which include phospholipids and glycolipids (e.g., DMPE-PEG2000) ; and (3) “derived lipids” such as steroids. Further, as used herein, lipids also encompass lipidoid compounds. The term “lipidoid compound, ” also simply “lipidoid” , refers to a lipid-like compound (e.g. an amphiphilic compound with lipid-like physical properties) .
The term “lipid nanoparticle” or “LNP” refers to a particle having at least one dimension on the order of nanometers (nm) (e.g., 1 to 1,000 nm) , which contains one or more types of lipid molecules. The LNP provided herein can further contain at least one non-lipid payload molecule (e.g., one or more nucleic acid molecules) . In some embodiments, the LNP comprises a non-lipid payload molecule either partially or completely encapsulated inside a lipid shell. Particularly, in some embodiments, wherein the payload is a negatively charged molecule (e.g., mRNA encoding a viral protein) , and the lipid components of the LNP comprise at least one cationic lipid. Without being bound by the theory, it is contemplated that the cationic lipids can interact with the negatively charged payload molecules and facilitates incorporation and/or encapsulation of the payload into the LNP during LNP formation. Other lipids that can form part of a LNP as provided herein include but are not limited to neutral lipids and charged lipids, such as steroids, polymer conjugated lipids, and various zwitterionic lipids. In certain embodiments, a LNP according to the present disclosure comprises one or more cationic lipids of Formula (1) to (40) (and sub-formulas thereof) as described herein. In certain embodiments, a LNP according to the present disclosure comprises one or more polymer conjugated lipids of Formula (41) to (46) (and sub-formulas thereof) as described herein.
The term “cationic lipid” refers to a lipid that is either positively charged at any pH value or hydrogen ion activity of its environment, or capable of being positively charged in response to the pH value or hydrogen ion activity of its environment (e.g., the environment of its intended use) . Thus, the term “cationic” encompasses both “permanently cationic” and “cationisable. ” In certain embodiments, the positive charge in a cationic lipid results from the presence of a quaternary nitrogen atom. In certain embodiments, the cationic lipid comprises a zwitterionic lipid that assumes a positive charge in the environment of its intended use (e.g., at physiological pH) . In certain embodiments, the cationic lipid is one or more lipids of Formula (1) to (40) (and sub-formulas thereof) as described herein.
The term “polymer conjugated lipid” refers to a molecule comprising both a lipid portion and a polymer portion. An example of a polymer conjugated lipid is a pegylated lipid (PEG-lipid) , in which the polymer portion comprises a polyethylene glycol. In certain embodiments, the polymer conjugated lipid is one or more lipids of Formula (41) to (46) (and sub-formulas thereof) as described herein.

The term “encoding nucleic acid” or grammatical equivalents thereof as it is used in reference to nucleic acid molecule encompasses (a) a nucleic acid molecule in its native state or when manipulated by methods well known to those skilled in the art that can be transcribed to produce mRNA which is then translated into a peptide and/or polypeptide, and (b) the mRNA molecule itself. The antisense strand is the complement of such a nucleic acid molecule, and the encoding sequence can be deduced therefrom. The term “coding region” refers to a portion in an encoding nucleic acid sequence that is translated into a peptide or polypeptide. The term “untranslated region” or “UTR” refers to the portion of an encoding nucleic acid that is not translated into a peptide or polypeptide. Depending on the orientation of a UTR with respect to the coding region of a nucleic acid molecule, a UTR is referred to as the 5’-UTR if located to the 5’-end of a coding region, and a UTR is referred to as the 3’-UTR if located to the 3’-end of a coding region.
The term “mRNA” as used herein refers to a message RNA molecule comprising one or more open reading frame (ORF) that can be translated by a cell or an organism provided with the mRNA to produce one or more peptide or protein product. The region containing the one or more ORFs is referred to as the coding region of the mRNA molecule. In certain embodiments, the mRNA molecule further comprises one or more untranslated regions (UTRs) .
In certain embodiments, the mRNA is a monocistronic mRNA that comprises only one ORF. In certain embodiments, the monocistronic mRNA encodes a peptide or protein comprising at least one epitope of a selected antigen (e.g., a pathogenic antigen or a tumor associated antigen) . In other embodiments, the mRNA is a multicistronic mRNA that comprises two or more ORFs. In certain embodiments, the multiecistronic mRNA encodes two or more peptides or proteins that can be the same or different from each other. In certain embodiments, each peptide or protein encoded by a multicistronic mRNA comprises at least one epitope of a selected antigen. In certain embodiments, different peptide or protein encoded by a multicistronic mRNA each comprises at least one epitope of different antigens. In any of the embodiments described herein, the at least one epitope can be at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, or at least 10 epitopes of an antigen.
The term “nucleobases” encompasses purines and pyrimidines, including natural compounds adenine, thymine, guanine, cytosine, uracil, inosine, and natural or synthetic analogs or derivatives thereof.
The term “functional nucleotide analog” as used herein refers to a modified version of a canonical nucleotide A, G, C, U or T that (a) retains the base-pairing properties of the corresponding canonical nucleotide, and (b) contains at least one chemical modification to (i) the nucleobase, (ii) the sugar group, (iii) the phosphate group, or (iv) any combinations of (i) to (iii) , of the corresponding natural nucleotide. As used herein, base pairing encompasses not only the canonical Watson-Crick adenine-thymine, adenine-uracil, or guanine-cytosine base pairs, but also base pairs formed between canonical nucleotides and functional nucleotide analogs or between a pair of functional nucleotide analogs, wherein the arrangement of hydrogen bond donors and hydrogen bond acceptors permits hydrogen bonding between a modified nucleobase and a canonical nucleobase or between two complementary modified nucleobase structures. For example, a functional analog of guanosine (G) retains the ability to base-pair with cytosine (C) or a functional analog of cytosine. One example of such non-canonical base pairing is the base pairing between the modified nucleotide inosine and adenine, cytosine, or uracil. As described herein, a functional nucleotide analog can be either naturally occurring or non-naturally occurring. Accordingly, a nucleic acid molecule containing a functional nucleotide analog can have at least one modified nucleobase, sugar group and/or internucleoside linkage. Exemplary chemical modifications to the nucleobases, sugar groups, or internucleoside linkages of a nucleic acid molecule are provided herein.
The terms “translational enhancer element, ” “TEE” and “translational enhancers” as used herein refers to an region in a nucleic acid molecule that functions to promotes translation of a coding sequence of the nucleic acid into a protein or peptide product, such as via cap-dependent or cap-independent translation. A TEE typically locates in the UTR region of a nucleic acid molecule (e.g., mRNA) and enhance the translational level of a coding sequence located either upstream or downstream. For example, a TEE in a 5’-UTR of a nucleic acid molecule can locate between the promoter and the starting codon of the nucleic acid molecule. Various TEE sequences are known in the art (Wellensiek et al. Genome-wide profiling of human cap-independent translation-enhancing elements, Nature Methods, 2013 Aug; 10 (8) : 747–750; Chappell et al. PNAS June 29, 2004 101 (26) 9590-9594) . Some TEEs are known to be conserved across multiple species (Pánek et al. Nucleic Acids Research, Volume 41, Issue 16, 1 September 2013, Pages 7625–7634) .
As used herein, the term “stem-loop sequence” refers to a single-stranded polynucleotide sequence having at least two regions that are complementary or substantially complementary to each other when read in opposite directions, and thus capable of base-pairing with each other to form at least one double helix and an unpaired loop. The resulting structure is known as a stem-loop structure, a hairpin, or a hairpin loop, which is a secondary structure found in many RNA molecules.
The term “peptide” as used herein refers to a polymer containing between two and fifty (2-50) amino acid residues linked by one or more covalent peptide bond (s) . The terms apply to naturally occurring amino acid polymers as well as amino acid polymers in which one or more amino acid residues is a non-naturally occurring amino acid (e.g., an amino acid analog or non-natural amino acid) .
The terms “polypeptide” and “protein” are used interchangeably herein to refer to a polymer of greater than fifty (50) amino acid residues linked by covalent peptide bonds. That is, a description directed to a polypeptide applies equally to a description of a protein, and vice versa. The terms apply to naturally occurring amino acid polymers as well as amino acid polymers in which one or more amino acid residues is a non-naturally occurring amino acid (e.g., an amino acid analog) . As used herein, the terms encompass amino acid chains of any length, including full length proteins (e.g., antigens) .
In the context of a peptide or polypeptide, the term “derivative” as used herein refers to a peptide or polypeptide that comprises an amino acid sequence of the viral peptide or protein, or a fragment of a viral peptide or protein, which has been altered by the introduction of amino acid residue substitutions, deletions, or additions. The term “derivative” as used herein also refers to a viral peptide or protein, or a fragment of a viral peptide or protein, which has been chemically modified, e.g., by the covalent attachment of any type of molecule to the polypeptide. For example, but not by way of limitation, a viral peptide or protein or a fragment of the viral peptide or protein may be chemically modified, e.g., by glycosylation, acetylation, pegylation, phosphorylation, amidation, derivatization by known protecting/blocking groups, proteolytic cleavage, chemical cleavage, formulation, metabolic synthesis of tunicamycin, linkage to a cellular ligand or other protein, etc. The derivatives are modified in a manner that is different from naturally occurring or starting peptide or polypeptides, either in the type or location of the molecules attached. Derivatives further include deletion of one or more chemical groups which are naturally present on the viral peptide or protein. Further, a derivative of a viral peptide or protein or a fragment of a viral peptide or protein may contain one or more non-classical amino acids. In specific embodiments, a derivative is a functional derivative of the native or unmodified peptide or polypeptide from which it was derived.
The term “functional derivative” refers to a derivative that retains one or more functions or activities of the naturally occurring or starting peptide or polypeptide from which it was derived. For example, a functional derivative of a coronavirus S protein may retain the ability to bind one or more of its receptors on a host cell. For example, a functional derivative of a coronavirus N protein may retain the ability to bind RNA or the package viral genome.
The term “identity” refers to a relationship between the sequences of two or more polypeptide molecules or two or more nucleic acid molecules, as determined by aligning and comparing the sequences. “Percent (%) amino acid sequence identity” with respect to a reference polypeptide sequence is defined as the percentage of amino acid residues in a candidate sequence that are identical with the amino acid residues in the reference polypeptide sequence, after aligning the sequences and introducing gaps, if necessary, to achieve the maximum percent sequence identity, and not considering any conservative substitutions as part of the sequence identity. Alignment for purposes of determining percent amino acid sequence identity can be achieved in various ways that are within the skill in the art, for instance, using publicly available computer software such as BLAST, BLAST-2, ALIGN, or MEGALIGN (DNAStar, Inc. ) software. Those skilled in the art can determine appropriate parameters for aligning sequences, including any algorithms needed to achieve maximal alignment over the full length of the sequences being compared.
A “modification” of an amino acid residue/position refers to a change of a primary amino acid sequence as compared to a starting amino acid sequence, wherein the change results from a sequence alteration involving said amino acid residue/position. For example, typical modifications include substitution of the residue with another amino acid (e.g., a conservative or non-conservative substitution) , insertion of one or more (e.g., generally fewer than 5, 4, or 3) amino acids adjacent to said residue/position, and/or deletion of said residue/position.
In the context of a peptide or polypeptide, the term “fragment” as used herein refers to a peptide or polypeptide that comprises less than the full length amino acid sequence. Such a fragment may arise, for example, from a truncation at the amino terminus, a truncation at the carboxy terminus, and/or an internal deletion of a residue (s) from the amino acid sequence. Fragments may, for example, result from alternative RNA splicing or from in vivo protease activity. In certain embodiments, fragments refers to polypeptides comprising an amino acid sequence of at least 5 contiguous amino acid residues, at least 10 contiguous amino acid residues, at least 15 contiguous amino acid residues, at least 20 contiguous amino acid residues, at least 25 contiguous amino acid residues, at least 30 contiguous amino acid residues, at least 40 contiguous amino acid residues, at least 50 contiguous amino acid residues, at least 60 contiguous amino residues, at least 70 contiguous amino acid residues, at least 80 contiguous amino acid residues, at least 90 contiguous amino acid residues, at least contiguous 100 amino acid residues, at least 125 contiguous amino acid residues, at least 150 contiguous amino acid residues, at least 175 contiguous amino acid residues, at least 200 contiguous amino acid residues, at least 250, at least 300, at least 350, at least 400, at least 450, at least 500, at least 550, at least 600, at least 650, at least 700, at least 750, at least 800, at least 850, at least 900, or at least 950 contiguous amino acid residues of the amino acid sequence of a polypeptide. In a specific embodiment, a fragment of a polypeptide retains at least 1, at least 2, at least 3, or more functions of the polypeptide.
The term “immunogenic fragment” as used herein in the context of a peptide or polypeptide (e.g., a protein) , refers to a fragment of a peptide or polypeptide that retains the ability of the peptide or polypeptide in eliciting an immune response upon contacting the immune system of a mammal, including innate immune responses and/or adaptive immune responses. In some embodiments, an immunogenic fragment of a peptide or polypeptide can be an epitope.
The term “antigen” refers to a substance that can be recognized by the immune system of a subject (including by the adaptive immune system) , and is capable of triggering an immune response after the subject is contacted with the antigen (including an antigen-specific immune response) . In certain embodiments, the antigen is a protein associated with a diseased cell, such as a cell infected by a pathogen or a neoplastic cell (e.g., tumor associated antigen (TAA) ) .
An “epitope” is the site on the surface of an antigen molecule to which a single antibody molecule binds, such as a localized region on the surface of an antigen that is capable of being bound to one or more antigen binding regions of an antibody, and that has antigenic or immunogenic activity in an animal, such as a mammal (e.g., a human) , that is capable of eliciting an immune response. An epitope having immunogenic activity is a portion of a polypeptide that elicits an antibody response in an animal. An epitope having antigenic activity is a portion of a polypeptide to which an antibody binds as determined by any method well known in the art, including, for example, by an immunoassay. Antigenic epitopes need not necessarily be immunogenic. Epitopes often consist of chemically active surface groupings of molecules such as amino acids or sugar side chains and have specific three dimensional structural characteristics as well as specific charge characteristics. Antibody epitopes may be linear epitopes or conformational epitopes. Linear epitopes are formed by a continuous sequence of amino acids in a protein. Conformational epitopes are formed of amino acids that are discontinuous in the protein sequence, but which are brought together upon folding of the protein into its three-dimensional structure. Induced epitopes are formed when the three dimensional structure of the protein is in an altered conformation, such as following activation or binding of another protein or ligand. In certain embodiments, an epitope is a three-dimensional surface feature of a polypeptide. In other embodiments, an epitope is linear feature of a polypeptide. Generally an antigen has several or many different epitopes and may react with many different antibodies.
The terms “severe acute respiratory syndrome coronavirus 2” or “SARS-CoV-2” or “2019-nCoV” are used interchangeably herein to refer to the coronavirus that caused the pandemic of infectious diseases of which the first cases were identified in 2019. GenBank

The term “SARS-CoV-2 variant” as used herein refers to a mutated version of coronavirus SARS-CoV-2, wherein the genome of the variant contains at least one mutation as compared to the genome of SARS-CoV-2. Exemplary SARS-CoV-2 variants have emerged in humans and supplanted ancestral strains. One of the first identified variants includes the D614G mutation in the gene encoding the spike (S) protein, which enhances viral infectivity and shifts S protein conformation toward an angiotensin-converting enzyme 2 (ACE2) -binding fusion-competent state, without significantly modifying sensitivity to antibody neutralization. Additional SARS-CoV-2 variants have appeared in multiple countries, with combinations of mutations and deletions in the receptor-binding domain (RBD) and N-terminal domain of S protein, as well as in other proteins. The B. 1.1.7 variant emerged in the United Kingdom, the B. 1.351 variant (also termed 501Y. V2) in South Africa and the P. 1 and P. 2 variant emerged in Brazil. The RBD mutation N501Y is present in B. 1.1.7 and B. 1.351 (Zahradník, J. et al. SARS-CoV-2 RBD in vitro evolution follows contagious mutation spread, yet generates an able infection inhibitor. Preprint at BioRxiv doi. org/10.1101/2021.01.06.425392 (2021) ) . The RBD mutations E484K and K417N/T are present in the B. 1.351 and P. 1 strains (Planas, D., Bruel, T., Grzelak, L. et al. Sensitivity of infectious SARS-CoV-2 B. 1.1.7 and B. 1.351 variants to neutralizing antibodies. Nat Med 27, 917–924 (2021) . doi. org/10.1038/s41591-021-01318-5) .
The terms “SARS-CoV-2 South Africa Variant” or “SARS-CoV-2 B. 1.351” are used interchangeably herein to refer to the variant strain of SARS-CoV-2 that was first detected in South Africa during the COVID-19 pandemic in 2020. GenBank

The term “genetic vaccine” as used herein refers to a therapeutic or prophylactic composition comprising at least one nucleic acid molecule encoding an antigen associated with a target disease (e.g., an infectious disease or a neoplastic disease) . Administration of the vaccine to a subject ( “vaccination” ) allows for the production of the encoded peptide or protein, thereby eliciting an immune response against the target disease in the subject. In certain embodiments, the immune response comprises adaptive immune response, such as the production of antibodies against the encoded antigen, and/or activation and proliferations of immune cells capable of specifically eliminating diseased cells expressing the antigen. In certain embodiments, the immune response further comprises innate immune response. According to the present disclosure, a vaccine can be administered to a subject either before or after the onset of clinical symptoms of the target disease. In some embodiments, vaccination of a healthy or asymptomatic subject renders the vaccinated subject immune or less susceptible to the development of the target disease. In some embodiments, vaccination of a subject showing symptoms of the disease improves the condition of, or treats, the disease in the vaccinated subject.
The term “vector” refers to a substance that is used to carry or include a nucleic acid sequence, including for example, a nucleic acid sequence encoding a viral peptide or protein as described herein, in order to introduce a nucleic acid sequence into a host cell, or serve as a transcription template to carry out in vitro transcription reaction in a cell-free system to produce mRNA. Vectors applicable for use include, for example, expression vectors, plasmids, phage vectors, viral vectors, episomes, and artificial chromosomes, which can include selection sequences or markers operable for stable integration into a host cell’s chromosome. Additionally, the vectors can include one or more selectable marker genes and appropriate transcription or translation control sequences. Selectable marker genes that can be included, for example, provide resistance to antibiotics or toxins, complement auxotrophic deficiencies, or supply critical nutrients not in the culture media. Transcription or translation control sequences can include constitutive and inducible promoters, transcription enhancers, transcription terminators, and the like, which are well known in the art. When two or more nucleic acid molecules are to be co-transcribed or co-translated (e.g., nucleic acid molecules encoding two or more different viral peptides or proteins) , both nucleic acid molecules can be inserted, for example, into a single expression vector or in separate expression vectors. For single vector transcription and/or translation, the encoding nucleic acids can be operationally linked to one common transcription or translation control sequence or linked to different transcription or translation control sequences, such as one inducible promoter and one constitutive promoter. The introduction of nucleic acid molecules into a host cell can be confirmed using methods well known in the art. Such methods include, for example, nucleic acid analysis such as Northern blots or polymerase chain reaction (PCR) amplification of mRNA, immunoblotting for expression of gene products, or other suitable analytical methods to test the expression of an introduced nucleic acid sequence or its corresponding gene product. It is understood by those skilled in the art that the nucleic acid molecules are expressed in a sufficient amount to produce a desired product (e.g., a mRNA transcript of the nucleic acid as described herein) , and it is further understood that expression levels can be optimized to obtain sufficient expression using methods well known in the art.
The terms “innate immune response” and “innate immunity” are recognized in the art, and refer to non-specific defense mechanism a body’s immune system initiates upon recognition of pathogen-associated molecular patterns, which involves different forms of cellular activities, including cytokine production and cell death through various pathways. As used herein, innate immune responses include, without limitation, increased production of inflammation cytokines (e.g., type I interferon or IL-10 production) , activation of the NFκB pathway, increased proliferation, maturation, differentiation and/or survival of immune cells, and in some cases, induction of cell apoptosis. Activation of the innate immunity can be detected using methods known in the art, such as measuring the (NF) -κB activation.
The terms “adaptive immune response” and “adaptive immunity” are recognized in the art, and refer to antigen-specific defense mechanism a body’s immune system initiates upon recognition of a specific antigen, which include both humoral response and cell-mediated responses. As used herein, adaptive immune responses include cellular responses that is triggered and/or augmented by a vaccine composition, such as a genetic composition described herein. In some embodiments, the vaccine composition comprises an antigen that is the target of the antigen-specific adaptive immune response. In other embodiments, the vaccine composition, upon administration, allows the production in an immunized subject of an antigen that is the target of the antigen-specific adaptive immune response. Activation of an adaptive immune response can be detected using methods known in the art, such as measuring the antigen-specific antibody production, or the level of antigen-specific cell-mediated cytotoxicity.
“Antibody-dependent cell-mediated cytotoxicity” or “ADCC” refers to a form of cytotoxicity in which secreted immunoglobulin bound onto Fc receptors (FcRs) present on certain cytotoxic cells (e.g., Natural Killer (NK) cells, neutrophils, and macrophages) enable these cytotoxic effector cells to bind specifically to an antigen-bearing target cell and subsequently kill the target cell with cytotoxins. The antibodies “arm” the cytotoxic cells and are absolutely required for such killing. NK cells, the primary cells for mediating ADCC, express FcγRIII only, whereas monocytes express FcγRI, FcγRII, and FcγRIII. FcR expression on hematopoietic cells is known (see, e.g., Ravetch and Kinet, 1991, Annu. Rev. Immunol. 9: 457-92) . To assess ADCC activity of a molecule of interest, an in vitro ADCC assay (see, e.g., US Pat. Nos. 5,500,362 and 5,821,337) can be performed. Useful effector cells for such assays include peripheral blood mononuclear cells (PBMC) and Natural Killer (NK) cells. Alternatively or additionally, ADCC activity of the molecule of interest may be assessed in vivo, for example, in an animal model (see, e.g., Clynes et al., 1998, Proc. Natl. Acad. Sci. USA 95: 652-56) . Antibodies with little or no ADCC activity may be selected for use.
“Antibody-dependent cellular phagocytosis” or “ADCP” refers to the destruction of target cells via monocyte or macrophage-mediated phagocytosis when immunoglobulin bound onto Fc receptors (FcRs) present on certain phagocytotic cells (e.g., neutrophils, monocytes, and macrophages) enable these phagocytotic cells to bind specifically to an antigen-bearing target cell and subsequently kill the target cell. To assess ADCP activity of a molecule of interest, an in vitro ADCP assay (see, e.g., Bracher et al., 2007, J. Immunol. Methods 323: 160-71) can be performed. Useful phagocytotic cells for such assays include peripheral blood mononuclear cells (PBMC) , purified monocytes from PBMC, or U937 cells differentiated to the mononuclear type. Alternatively or additionally, ADCP activity of the molecule of interest may be assessed in vivo, for example, in an animal model (see, e.g., Wallace et al., 2001, J. Immunol. Methods 248: 167-82) . Antibodies with little or no ADCP activity may be selected for use.
“Fc receptor” or “FcR” describes a receptor that binds to the Fc region of an antibody. An exemplary FcR is a native sequence human FcR. Moreover, an exemplary FcR is one that binds an IgG antibody (e.g., a gamma receptor) and includes receptors of the FcγRI, FcγRII, and FcγRIII subclasses, including allelic variants and alternatively spliced forms of these receptors. FcγRII receptors include FcγRIIA (an “activating receptor” ) and FcγRIIB (an “inhibiting receptor” ) , which have similar amino acid sequences that differ primarily in the cytoplasmic domains thereof (see, e.g.,
1997, Annu. Rev. Immunol. 15: 203-34) . Various FcRs are known (see, e.g., Ravetch and Kinet, 1991, Annu. Rev. Immunol. 9: 457-92; Capel et al., 1994, Immunomethods 4: 25-34; and de Haas et al., 1995, J. Lab. Clin. Med. 126: 330-41) . Other FcRs, including those to be identified in the future, are encompassed by the term “FcR” herein. The term also includes the neonatal receptor, FcRn, which is responsible for the transfer of maternal IgGs to the fetus (see, e.g., Guyer et al., 1976, J. Immunol. 117: 587-93; and Kim et al., 1994, Eu. J. Immunol. 24: 2429-34) . Antibody variants with improved or diminished binding to FcRs have been described (see, e.g., WO 2000/42072; U.S. Pat. Nos. 7,183,387; 7,332,581; and 7.335,742; Shields et al. 2001, J. Biol. Chem. 9 (2) : 6591-604) .
“Complement dependent cytotoxicity” or “CDC” refers to the lysis of a target cell in the presence of complement. Activation of the classical complement pathway is initiated by the binding of the first component of the complement system (C1q) to antibodies (of the appropriate subclass) which are bound to their cognate antigen. To assess complement activation, a CDC assay (see, e.g., Gazzano-Santoro et al., 1996, J. Immunol. Methods 202: 163) may be performed. Polypeptide variants with altered Fc region amino acid sequences (polypeptides with a variant Fc region) and increased or decreased C1q binding capability have been described (see, e.g., US Pat. No. 6,194,551; WO 1999/51642; Idusogie et al., 2000, J. Immunol. 164: 4178-84) . Antibodies with little or no CDC activity may be selected for use.
The term “antibody” is intended to include a polypeptide product of B cells within the immunoglobulin class of polypeptides that is able to bind to a specific molecular antigen and is composed of two identical pairs of polypeptide chains, wherein each pair has one heavy chain (about 50-70 kDa) and one light chain (about 25 kDa) , each amino-terminal portion of each chain includes a variable region of about 100 to about 130 or more amino acids, and each carboxy-terminal portion of each chain includes a constant region. See, e.g., Antibody Engineering (Borrebaeck ed., 2d ed. 1995) ; and Kuby, Immunology (3d ed. 1997) . In specific embodiments, the specific molecular antigen can be bound by an antibody provided herein, including a polypeptide, a fragment or an epitope thereof. Antibodies also include, but are not limited to, synthetic antibodies, recombinantly produced antibodies, camelized antibodies, intrabodies, anti-idiotypic (anti-Id) antibodies, and functional fragments of any of the above, which refers to a portion of an antibody heavy or light chain polypeptide that retains some or all of the binding activity of the antibody from which the fragment was derived. Non-limiting examples of functional fragments include single-chain Fvs (scFv) (e.g., including monospecific, bispecific, etc. ) , Fab fragments, F (ab’) fragments, F (ab)
2 fragments, F (ab’)
2 fragments, disulfide-linked Fvs (dsFv) , Fd fragments, Fv fragments, diabody, triabody, tetrabody, and minibody. In particular, antibodies provided herein include immunoglobulin molecules and immunologically active portions of immunoglobulin molecules, for example, antigen-binding domains or molecules that contain an antigen-binding site (e.g., one or more CDRs of an antibody) . Such antibody fragments can be found in, for example, Harlow and Lane, Antibodies: A Laboratory Manual (1989) ; Mol. Biology and Biotechnology: A Comprehensive Desk Reference (Myers ed., 1995) ; Huston et al., 1993, Cell Biophysics 22: 189-224; Plückthun and Skerra, 1989, Meth. Enzymol. 178: 497-515; and Day, Advanced Immunochemistry (2d ed. 1990) . The antibodies provided herein can be of any class (e.g., IgG, IgE, IgM, IgD, and IgA) or any subclass (e.g., IgG1, IgG2, IgG3, IgG4, IgA1, and IgA2) of immunoglobulin molecule.
The term “administer” or “administration” refers to the act of injecting or otherwise physically delivering a substance as it exists outside the body (e.g., a lipid nanoparticle composition as described herein) into a patient, such as by mucosal, intradermal, intravenous, intramuscular delivery, and/or any other method of physical delivery described herein or known in the art. When a disease, disorder, condition, or a symptom thereof, is being treated, administration of the substance typically occurs after the onset of the disease, disorder, condition, or symptoms thereof. When a disease, disorder, condition, or symptoms thereof, are being prevented, administration of the substance typically occurs before the onset of the disease, disorder, condition, or symptoms thereof.
“Chronic” administration refers to administration of the agent (s) in a continuous mode (e.g., for a period of time such as days, weeks, months, or years) as opposed to an acute mode, so as to maintain the initial therapeutic effect (activity) for an extended period of time. “Intermittent” administration is treatment that is not consecutively done without interruption, but rather is cyclic in nature.
The term “targeted delivery” or the verb form “target” as used herein refers to the process that promotes the arrival of a delivered agent (such as a therapeutic payload molecule in a lipid nanoparticle composition as described herein) at a specific organ, tissue, cell and/or intracellular compartment (referred to as the targeted location) more than any other organ, tissue, cell or intracellular compartment (referred to as the non-target location) . Targeted delivery can be detected using methods known in the art, for example, by comparing the concentration of the delivered agent in a targeted cell population with the concentration of the delivered agent at a non-target cell population after systemic administration. In certain embodiments, targeted delivery results in at least 2 fold higher concentration at a targeted location as compared to a non-target location.
An “effective amount” is generally an amount sufficient to reduce the severity and/or frequency of symptoms, eliminate the symptoms and/or underlying cause, prevent the occurrence of symptoms and/or their underlying cause, and/or improve or remediate the damage that results from or is associated with a disease, disorder, or condition, including, for example, infection and neoplasia. In some embodiments, the effective amount is a therapeutically effective amount or a prophylactically effective amount.
The term “therapeutically effective amount” as used herein refers to the amount of an agent (e.g., a vaccine composition) that is sufficient to reduce and/or ameliorate the severity and/or duration of a given disease, disorder, or condition, and/or a symptom related thereto (e.g., an infectious disease such as caused by viral infection, or a neoplastic disease such as cancer) . A “therapeutically effective amount” of a substance/molecule/agent of the present disclosure (e.g., the lipid nanoparticle composition as described herein) may vary according to factors such as the disease state, age, sex, and weight of the individual, and the ability of the substance/molecule/agent to elicit a desired response in the individual. A therapeutically effective amount encompasses an amount in which any toxic or detrimental effects of the substance/molecule/agent are outweighed by the therapeutically beneficial effects. In certain embodiments, the term “therapeutically effective amount” refers to an amount of a lipid nanoparticle composition as described herein or a therapeutic or prophylactic agent contained therein (e.g., a therapeutic mRNA) effective to “treat” a disease, disorder, or condition, in a subject or mammal.
A “prophylactically effective amount” is an amount of a pharmaceutical composition that, when administered to a subject, will have the intended prophylactic effect, e.g., preventing, delaying, or reducing the likelihood of the onset (or reoccurrence) of a disease, disorder, condition, or associated symptom (s) (e.g., an infectious disease such as caused by viral infection, or a neoplastic disease such as cancer) . Typically, but not necessarily, since a prophylactic dose is used in subjects prior to or at an earlier stage of a disease, disorder, or condition, a prophylactically effective amount may be less than a therapeutically effective amount. The full therapeutic or prophylactic effect does not necessarily occur by administration of one dose, and may occur only after administration of a series of doses.

Some coronaviruses also encode an envelope-associated hemagglutinin-esterase (HE) protein. Among these structural proteins, the spike forms large protrusions from the virus surface, giving coronaviruses the appearance of having crowns. It is further contemplated that in addition to mediating virus entry, the spike protein may play a role in determining the viral host range and tissue tropism and a major inducer of host immune responses.

Accordingly, in some embodiments, the therapeutic nucleic acid of the present disclosure encodes the coronavirus S protein, or an immunogenic fragment of the S protein, or a functional derivative of the S protein or the immunogenic fragment thereof. In specific embodiments, the immunogenic fragment of the S protein is selected from the ectodomain, the S1 subunit, the receptor binding domain (RBD) , and the receptor binding motif (RBM) .

6.3.2 5’-Cap Structure
Without being bound by the theory, it is contemplated that, a 5’-cap structure of a polynucleotide is involved in nuclear export and increasing polynucleotide stability and binds the mRNA Cap Binding Protein (CBP) , which is responsible for polynucleotide stability in the cell and translation competency through the association of CBP with poly-A binding protein to form the mature cyclic mRNA species. The 5’-cap structure further assists the removal of 5’-proximal introns removal during mRNA splicing. Accordingly, in some embodiments, the nucleic acid molecules of the present disclosure comprise a 5’-cap structure.
Nucleic acid molecules may be 5’-end capped by the endogenous transcription machinery of a cell to generate a 5’-ppp-5’-triphosphate linkage between a terminal guanosine cap residue and the 5’-terminal transcribed sense nucleotide of the polynucleotide. This 5’-guanylate cap may then be methylated to generate an N7-methyl-guanylate residue. The ribose sugars of the terminal and/or anteterminal transcribed nucleotides of the 5’ end of the polynucleotide may optionally also be 2’-O-methylated. 5’-decapping through hydrolysis and cleavage of the guanylate cap structure may target a nucleic acid molecule, such as an mRNA molecule, for degradation.
In some embodiments, the nucleic acid molecules of the present disclosure comprise one or more alterations to the natural 5’-cap structure generated by the endogenous process. Without being bound by the theory, a modification on the 5’-cap may increase the stability of polynucleotide, increase the half-life of the polynucleotide, and could increase the polynucleotide translational efficiency.
Exemplary alterations to the natural 5’-Cap structure include generation of a non-hydrolyzable cap structure preventing decapping and thus increasing polynucleotide half-life. In some embodiments, because cap structure hydrolysis requires cleavage of 5’-ppp-5’ phosphorodiester linkages, in some embodiments, modified nucleotides may be used during the capping reaction. For example, in some embodiments, a Vaccinia Capping Enzyme from New England Biolabs (Ipswich, Mass. ) may be used with α-thio-guanosine nucleotides according to the manufacturer’s instructions to create a phosphorothioate linkage in the 5’-ppp-5’ cap. Additional modified guanosine nucleotides may be used, such as α-methyl-phosphonate and seleno-phosphate nucleotides.
Additional exemplary alterations to the natural 5’-Cap structure also include modification at the 2’-and/or 3’-position of a capped guanosine triphosphate (GTP) , a replacement of the sugar ring oxygen (that produced the carbocyclic ring) with a methylene moiety (CH
2) , a modification at the triphosphate bridge moiety of the cap structure, or a modification at the nucleobase (G) moiety.
Additional exemplary alterations to the natural 5’-cap structure include, but are not limited to, 2’-O-methylation of the ribose sugars of 5’-terminal and/or 5’-anteterminal nucleotides of the polynucleotide (as mentioned above) on the 2’-hydroxy group of the sugar. Multiple distinct 5’-cap structures can be used to generate the 5’-cap of a polynucleotide, such as an mRNA molecule. Additional exemplary 5’-Cap structures that can be used in connection with the present disclosure further include those described in International Patent Publication Nos. WO2008127688, WO 2008016473, and WO 2011015347, the entire contents of each of which are incorporated herein by reference.
In various embodiments, 5’-terminal caps can include cap analogs. Cap analogs, which herein are also referred to as synthetic cap analogs, chemical caps, chemical cap analogs, or structural or functional cap analogs, differ from natural (i.e., endogenous, wild-type, or physiological) 5’-caps in their chemical structure, while retaining cap function. Cap analogs may be chemically (i.e., non-enzymatically) or enzymatically synthesized and/linked to a polynucleotide.
For example, the Anti-Reverse Cap Analog (ARCA) cap contains two guanosines linked by a 5’-5’-triphosphate group, wherein one guanosine contains an N7-methyl group as well as a 3’-O-methyl group (i.e., N7, 3’-O-dimethyl-guanosine-5’-triphosphate-5’-guanosine, m
7G-3’mppp-G, which may equivalently be designated 3’ O-Me-m7G (5’) ppp (5’) G) . The 3’-O atom of the other, unaltered, guanosine becomes linked to the 5’-terminal nucleotide of the capped polynucleotide (e.g., an mRNA) . The N7-and 3’-O-methlyated guanosine provides the terminal moiety of the capped polynucleotide (e.g., mRNA) . Another exemplary cap structure is mCAP, which is similar to ARCA but has a 2’-O-methyl group on guanosine (i.e., N7, 2’-O-dimethyl-guanosine-5’-triphosphate-5’-guanosine, m
7Gm-ppp-G) .
In some embodiments, a cap analog can be a dinucleotide cap analog. As a non-limiting example, the dinucleotide cap analog may be modified at different phosphate positions with a boranophosphate group or a phophoroselenoate group such as the dinucleotide cap analogs described in U.S. Patent No.: 8,519,110, the entire content of which is herein incorporated by reference in its entirety.
In some embodiments, a cap analog can be a N7- (4-chlorophenoxyethyl) substituted dinucleotide cap analog known in the art and/or described herein. Non-limiting examples of N7- (4-chlorophenoxyethyl) substituted dinucleotide cap analogs include a N7- (4-chlorophenoxyethyl) -G (5’) ppp (5’) G and a N7- (4-chlorophenoxyethyl) -m3’-OG (5’) ppp (5’) G cap analog (see, e.g., the various cap analogs and the methods of synthesizing cap analogs described in Kore et al. Bioorganic &Medicinal Chemistry 2013 21: 4570-4574; the entire content of which is herein incorporated by reference) . In other embodiments, a cap analog useful in connection with the nucleic acid molecules of the present disclosure is a 4-chloro/bromophenoxyethyl analog.
In various embodiments, a cap analog can include a guanosine analog. Useful guanosine analogs include but are not limited to inosine, N1-methyl-guanosine, 2’-fluoro-guanosine, 7-deaza-guanosine, 8-oxo-guanosine, 2-amino-guanosine, LNA-guanosine, and 2-azido-guanosine.
Without being bound by the theory, it is contemplated that while cap analogs allow for the concomitant capping of a polynucleotide in an in vitro transcription reaction, up to 20%of transcripts remain uncapped. This, as well as the structural differences of a cap analog from the natural 5’-cap structures of polynucleotides produced by the endogenous transcription machinery of a cell, may lead to reduced translational competency and reduced cellular stability.
Accordingly, in some embodiments, a nucleic acid molecule of the present disclosure can also be capped post-transcriptionally, using enzymes, in order to generate more authentic 5’-cap structures. As used herein, the phrase “more authentic” refers to a feature that closely mirrors or mimics, either structurally or functionally, an endogenous or wild type feature. That is, a “more authentic” feature is better representative of an endogenous, wild-type, natural or physiological cellular function, and/or structure as compared to synthetic features or analogs of the prior art, or which outperforms the corresponding endogenous, wild-type, natural, or physiological feature in one or more respects. Non-limiting examples of more authentic 5’-cap structures useful in connection with the nucleic acid molecules of the present disclosure are those which, among other things, have enhanced binding of cap binding proteins, increased half-life, reduced susceptibility to 5’-endonucleases, and/or reduced 5’-decapping, as compared to synthetic 5’-cap structures known in the art (or to a wild-type, natural or physiological 5’-cap structure) . For example, in some embodiments, recombinant Vaccinia Virus Capping Enzyme and recombinant 2’-O-methyltransferase enzyme can create a canonical 5’-5’-triphosphate linkage between the 5’-terminal nucleotide of a polynucleotide and a guanosine cap nucleotide wherein the cap guanosine contains an N7-methylation and the 5’-terminal nucleotide of the polynucleotide contains a 2’-O-methyl. Such a structure is termed the Cap1 structure. This cap results in a higher translational-competency, cellular stability, and a reduced activation of cellular pro-inflammatory cytokines, as compared, e.g., to other 5’cap analog structures known in the art. Other exemplary cap structures include 7mG (5’) ppp (5’) N, pN2p (Cap 0) , 7mG (5’) ppp (5’) NlmpNp (Cap 1) , 7mG (5’) -ppp (5’) NlmpN2mp (Cap 2) , and m (7) Gpppm (3) (6, 6, 2’) Apm (2’) Apm (2’) Cpm (2) (3, 2’) Up (Cap 4) .
Without being bound by the theory, it is contemplated that the nucleic acid molecules of the present disclosure can be capped post-transcriptionally, and because this process is more efficient, nearly 100%of the nucleic acid molecules may be capped.
6.3.3 Untranslated Regions (UTRs)
In some embodiments, the nucleic acid molecules of the present disclosure comprise one or more untranslated regions (UTRs) . In some embodiments, an UTR is positioned upstream to a coding region in the nucleic acid molecule, and is termed 5’-UTR. In some embodiments, an UTR is positioned downstream to a coding region in the nucleic acid molecule, and is termed 3’-UTR. The sequence of an UTR can be homologous or heterologous to the sequence of the coding region found in a nucleic acid molecule. Multiple UTRs can be included in a nucleic acid molecule and can be of the same or different sequences, and/or genetic origin.

In some embodiments, the UTR of a nucleic acid molecule of the present disclosure (e.g., mRNA) comprises at least one translation enhancer element (TEE) that functions to increase the amount of polypeptide or protein produced from the nucleic acid molecule.

6.3.4 The Polyadenylation (Poly-A) Regions
During natural RNA processing, a long chain of adenosine nucleotides (poly-A region) is normally added to messenger RNA (mRNA) molecules to increase the stability of the molecule. Immediately after transcription, the 3’-end of the transcript is cleaved to free a 3’-hydroxy. Then poly-A polymerase adds a chain of adenosine nucleotides to the RNA. The process, called polyadenylation, adds a poly-A region that is between 100 and 250 residues long.

6.3.8 Modification to the Sugar
In some embodiments, a functional nucleotide analog contains a non-canonical sugar group. In various embodiments, the non-canonical sugar group can be a 5-carbon or 6-carbon sugar (such as pentose, ribose, arabinose, xylose, glucose, galactose, or a deoxy derivative thereof) with one or more substitutions, such as a halo group, a hydroxy group, a thiol group, an alkyl group, an alkoxy group, an alkenyloxy group, an alkynyloxy group, an cycloalkyl group, an aminoalkoxy group, an alkoxyalkoxy group, an hydroxyalkoxy group, an amino group, an azido group, an aryl group, an aminoalkyl group, an aminoalkenyl group, an aminoalkynyl group, etc.
Generally, RNA molecules contains the ribose sugar group, which is a 5-membered ring having an oxygen. Exemplary, non-limiting alternative nucleotides include replacement of the oxygen in ribose (e.g., with S, Se, or alkylene, such as methylene or ethylene) ; addition of a double bond (e.g., to replace ribose with cyclopentenyl or cyclohexenyl) ; ring contraction of ribose (e.g., to form a 4-membered ring of cyclobutane or oxetane) ; ring expansion of ribose (e.g., to form a 6-or 7-membered ring having an additional carbon or heteroatom, such as for anhydrohexitol, altritol, mannitol, cyclohexanyl, cyclohexenyl, and morpholino (that also has a phosphoramidate backbone) ) ; multicyclic forms (e.g., tricyclo and “unlocked” forms, such as glycol nucleic acid (GNA) (e.g., R-GNA or S-GNA, where ribose is replaced by glycol units attached to phosphodiester bonds) , threose nucleic acid (TNA, where ribose is replace with α-L-threofuranosyl- (3’→2’) ) , and peptide nucleic acid (PNA, where 2-amino-ethyl-glycine linkages replace the ribose and phosphodiester backbone) .
In some embodiments, the sugar group contains one or more carbons that possess the opposite stereochemical configuration of the corresponding carbon in ribose. Thus, a nucleic acid molecule can include nucleotides containing, e.g., arabinose or L-ribose, as the sugar. In some embodiments, the nucleic acid molecule includes at least one nucleoside wherein the sugar is L-ribose, 2’-O-methyl-ribose, 2’-fluoro-ribose, arabinose, hexitol, an LNA, or a PNA.
6.3.9 Modifications to the Internucleoside Linkage
In some embodiments, the payload nucleic acid molecule of the present disclosure can contain one or more modified internucleoside linkage (e.g., phosphate backbone) . Backbone phosphate groups can be altered by replacing one or more of the oxygen atoms with a different substituent.
In some embodiments, the functional nucleotide analogs can include the replacement of an unaltered phosphate moiety with another internucleoside linkage as described herein. Examples of alternative phosphate groups include, but are not limited to, phosphorothioate, phosphoroselenates, boranophosphates, boranophosphate esters, hydrogen phosphonates, phosphoramidates, phosphorodiamidates, alkyl or aryl phosphonates, and phosphotriesters. Phosphorodithioates have both non-linking oxygens replaced by sulfur. The phosphate linker can also be altered by the replacement of a linking oxygen with nitrogen (bridged phosphoramidates) , sulfur (bridged phosphorothioates) , and carbon (bridged methylene-phosphonates) .
The alternative nucleosides and nucleotides can include the replacement of one or more of the non-bridging oxygens with a borane moiety (BH
3) , sulfur (thio) , methyl, ethyl, and/or methoxy. As a non-limiting example, two non-bridging oxygens at the same position (e.g., the alpha (α) , beta (β) or gamma (γ) position) can be replaced with a sulfur (thio) and a methoxy. The replacement of one or more of the oxygen atoms at the position of the phosphate moiety (e.g., α-thio phosphate) is provided to confer stability (such as against exonucleases and endonucleases) to RNA and DNA through the unnatural phosphorothioate backbone linkages. Phosphorothioate DNA and RNA have increased nuclease resistance and subsequently a longer half-life in a cellular environment.
Other internucleoside linkages that may be employed according to the present disclosure, including internucleoside linkages which do not contain a phosphorous atom, are described herein.

Nanoparticle compositions can be designed for one or more specific applications or targets. For example, a nanoparticle composition can be designed to deliver a therapeutic and/or prophylactic agent such as an RNA to a particular cell, tissue, organ, or system or group thereof in a mammal’s body. Physiochemical properties of nanoparticle compositions can be altered in order to increase selectivity for particular bodily targets. For instance, particle sizes can be adjusted based on the fenestration sizes of different organs. The therapeutic and/or prophylactic agent included in a nanoparticle composition can also be selected based on the desired delivery target or targets. For example, a therapeutic and/or prophylactic agent can be selected for a particular indication, condition, disease, or disorder and/or for delivery to a particular cell, tissue, organ, or system or group thereof (e.g., localized or specific delivery) . In certain embodiments, a nanoparticle composition can include an mRNA encoding a polypeptide of interest capable of being translated within a cell to produce the polypeptide of interest. Such a composition can be designed to be specifically delivered to a particular organ. In certain embodiments, a composition can be designed to be specifically delivered to a mammalian liver.
The amount of a therapeutic and/or prophylactic agent in a nanoparticle composition can depend on the size, composition, desired target and/or application, or other properties of the nanoparticle composition as well as on the properties of the therapeutic and/or prophylactic agent. For example, the amount of an RNA useful in a nanoparticle composition can depend on the size, sequence, and other characteristics of the RNA. The relative amounts of a therapeutic and/or prophylactic agent and other elements (e.g., lipids) in a nanoparticle composition can also vary. In some embodiments, the wt/wt ratio of the lipid component to a therapeutic and/or prophylactic agent in a nanoparticle composition can be from about 5: 1 to about 60: 1, such as about 5: 1, 6: 1, 7: 1, 8: 1, 9: 1, 10: 1, 11: 1, 12: 1, 13: 1, 14: 1, 15: 1, 16: 1, 17: 1, 18: 1, 19: 1, 20: 1, 22: 1, 25: 1, 30: 1, 35: 1, 40: 1, 45: 1, 50: 1, and 60: 1. For example, the wt/wt ratio of the lipid component to a therapeutic and/or prophylactic agent can be from about 10: 1 to about 40: 1. In certain embodiments, the wt/wt ratio is about 20: 1. The amount of a therapeutic and/or prophylactic agent in a nanoparticle composition can, for example, be measured using absorption spectroscopy (e.g., ultraviolet-visible spectroscopy) .
In some embodiments, a nanoparticle composition includes one or more RNAs, and the one or more RNAs, lipids, and amounts thereof can be selected to provide a specific N: P ratio. The N: P ratio of the composition refers to the molar ratio of nitrogen atoms in one or more lipids to the number of phosphate groups in an RNA. In some embodiments, a lower N: P ratio is selected. 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. For example, the N: P ratio may be about 5.0: 1, about 5.5: 1, about 5.67: 1, about 6.0: 1, about 6.5: 1, or about 7.0: 1. For example, the N: P ratio may be about 5.67: 1.
The physical properties of a nanoparticle composition can depend on the components thereof. For example, a nanoparticle composition including cholesterol as a structural lipid can have different characteristics compared to a nanoparticle composition that includes a different structural lipid. Similarly, the characteristics of a nanoparticle composition can depend on the absolute or relative amounts of its components. For instance, a nanoparticle composition including a higher molar fraction of a phospholipid may have different characteristics than a nanoparticle composition including a lower molar fraction of a phospholipid. Characteristics may also vary depending on the method and conditions of preparation of the nanoparticle composition.
Nanoparticle compositions may be characterized by a variety of methods. For example, microscopy (e.g., transmission electron microscopy or scanning electron microscopy) may be used to examine the morphology and size distribution of a nanoparticle composition. Dynamic light scattering or potentiometry (e.g., potentiometric titrations) may be used to measure zeta potentials. Dynamic light scattering may also be utilized to determine particle sizes. Instruments such as the Zetasizer Nano ZS (Malvem Instruments Ltd, Malvem, Worcestershire, UK) may also be used to measure multiple characteristics of a nanoparticle composition, such as particle size, polydispersity index, and zeta potential.
In various embodiments, the mean size of a nanoparticle composition can be between 10s of nm and 100s of nm. For example, the mean size can be from about 40 nm to about 150 nm, such as about 40 nm, 45 nm, 50 nm, 55 nm, 60 nm, 65 nm, 70 nm, 75 nm, 80 nm, 85 nm, 90 nm, 95 nm, 100 nm, 105 nm, 110 nm, 115 nm, 120 nm, 125 nm, 130 nm, 135 nm, 140 nm, 145 nm, or 150 nm. In some embodiments, the mean size of a nanoparticle composition can be from about 50 nm to about 100 nm, from about 50 nm to about 90 nm, from about 50 nm to about 80 nm, from about 50 nm to about 70 nm, from about 50 nm to about 60 nm, from about 60 nm to about 100 nm, from about 60 nm to about 90 nm, from about 60 nm to about 80 nm, from about 60 nm to about 70 nm, from about 70 nm to about 100 nm, from about 70 nm to about 90 nm, from about 70 nm to about 80 nm, from about 80 nm to about 100 nm, from about 80 nm to about 90 nm, or from about 90 nm to about 100 nm. In certain embodiments, the mean size of a nanoparticle composition can be from about 70 nm to about 100 nm. In some embodiments, the mean size can be about 80 nm. In other embodiments, the mean size can be about 100 nm.
A nanoparticle composition can be relatively homogenous. A polydispersity index can be used to indicate the homogeneity of a nanoparticle composition, e.g., the particle size distribution of the nanoparticle compositions. A small (e.g., less than 0.3) polydispersity index generally indicates a narrow particle size distribution. A nanoparticle composition can have a polydispersity index from about 0 to about 0.25, such as 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.10, 0.11, 0.12, 0.13, 0.14, 0.15, 0.16, 0.17, 0.18, 0.19, 0.20, 0.21, 0.22, 0.23, 0.24, or 0.25. In some embodiments, the polydispersity index of a nanoparticle composition 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. Nanoparticle compositions with relatively low charges, positive or negative, are generally desirable, as more highly charged species can interact undesirably with cells, tissues, and other elements in the body. In some embodiments, the zeta potential of a nanoparticle composition can be from about -10 mV to about +20 mV, from about -10 mV to about +15 mV, from about -10 mV to about +10 mV, from about -10 mV to about +5 mV, from about -10 mV to about 0 mV, from about -10 mV to about -5 mV, from about -5 mV to about +20 mV, from about -5 mV to about +15 mV, from about -5 mV to about +10 mV, from about -5 mV to about +5 mV, from about -5 mV to about 0 mV, from about 0 mV to about +20 mV, from about 0 mV to about +15 mV, from about 0 mV to about +10 mV, from about 0 mV to about +5 mV, from about +5 mV to about +20 mV, from about +5 mV to about +15 mV, or from about +5 mV to about +10 mV.
The efficiency of encapsulation of a therapeutic and/or prophylactic agent describes the amount of therapeutic and/or prophylactic agent that is encapsulated or otherwise associated with a nanoparticle composition after preparation, relative to the initial amount provided. The encapsulation efficiency is desirably high (e.g., close to 100%) . The encapsulation efficiency can be measured, for example, by comparing the amount of therapeutic and/or prophylactic agent 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 therapeutic and/or prophylactic agent (e.g., RNA) in a solution. For the nanoparticle compositions described herein, the encapsulation efficiency of a therapeutic and/or prophylactic agent 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%.

7. EXAMPLES
The examples in this section (i.e., Section 7) are offered by way of illustration, and not by way of limitation.

As shown in Figure 1A and Figure 1B, mRNA molecules were successfully produced by the in vitro transcription and maturation processes described above and were purified from the reaction system using HPLC (tested by BA method) .
7.2 Example 2: In vitro transfection and antigen expression analysis.
Different mRNAs molecules encoding coronavirus S protein antigens produced in Example 1 were transfected into expression cell lines such as HEK293 and Hela cultured cells to evaluate efficiency of in vitro expression of the mRNA molecules.
To assemble the mRNA-lipid complex, two separate tubes were set up with 1μL of Lipofectamine mixed with 30μL Opti-MEM, and with 1μg mRNA with 30μL Opti-MEM, respectively. The two samples were mixed and incubated at room temperature for 5 minutes. Fifty microliter of such a complex was used to transfect cells present in 1 well of a 24-well plate, and the cells were incubated in humidified 37℃/5%CO2 incubator until analysis.
Expression analysis. Cells were transferred from 24 hours post-transfection culture, and centrifuged at 200 RCF for 5 minutes at room temperature. Next, cells were treated with 4% (v/v) paraformaldehyde for 30 min, and washed with PBS. Next, cells were treated with 0.2% (v/v) Triton X-100 for 10 min, and washed with PBS. Next, cells were blocked with 5% (w/v) bovine serum albumin for 1 h, and washed with PBS. Next, cells were incubated with several rabbit anti-SARS-CoV-2 S protein antibodies at 4℃ for 1 h, and labeled with FITC-labeled anti-rabbit antibody (1: 200) as secondary antibody for 30 min, and washed with PBS and counter stained by DAPI. The signals were examined by confocal laser scanning microscopy.
Particularly, Figure 2 shows exemplary confocal fluorescence microscopy images of Hela cells transfected with an mRNA construct encoding a SARS-CoV-2 S protein RBD sequence (RBD sample 1) . Cells were incubated with 3 different monoclonal antibodies recognizing the S protein RBD of SARS-CoV-2, namely SARS-2-H014, SARS-2-mh001 and SARS-2-mh219, respectively.
As shown in Figure 2, in vitro transcribed mRNA molecules encoding the SARS-CoV-2 S protein RBD effectively transfected Hela cells. The transfected Hela cells expressed the encoded viral antigens at a satisfactory level, as can be recognized by the three monoclonal antibodies used in this study. The transfected Hela cells maintained normal cellular morphology, indicating a lack of cellular toxicity resulted from the expression of the encoded viral antigen.
Western blot. For the secreted proteins such as SARS-CoV-2 S protein or its fragments, cultures of cells transfected with the mRNA molecules produced in Example 1 was collected and analyzed by Western blot 24 hours post-transfection. Following SDS-PAGE, proteins were transferred onto blotting membrane. The blots were rinsed briefly with PBS and then incubated with added a rabbit anti-Spike RBD antibody for 2 hr at RT. The blots were washed extensively in PBS. HRP-conjugated anti-rabbit antibody was added and incubated for 1 hr at RT with gentle agitation. The membrane was washed with PBS, and incubated with added appropriate enzyme substrate solution to visualize protein bands.
Figure 3 shows an exemplary Western blot analysis of culture supernatant of Hela cells transfected with an mRNA molecule encoding a SARS-CoV-2 S protein RBD sequence. Particularly, the lanes labeled “RBD sample 1” and “RBD sample 2” were loaded with culture supernatant of Hela cells transfected with mRNA constructs encoding different SARS-CoV-2 S protein RBD sequences described herein, respectively. The lane labeled “rRBD-His” was loaded a recombinantly produced SARS-CoV-2 S protein RBD sequence fused to a C-terminal His-tag. The lane labeled “NT” was loaded cell culture supernatant of Hela cells transfected with an irrelevant mRNA construct as a negative control group.
As shown in Figure 3, the in vitro transcribed mRNA constructs encoding the SARS-CoV-2 S protein RBD effectively transfected Hela cells. The transfected Hela cells expressed and secreted the encoded viral antigen at a satisfactory level. The bands around about 30kD corresponded to secreted viral antigen in the monomeric form. The bands around about 60kD corresponded to secreted viral antigen in the dimeric form. Without being bound by the theory, it is contemplated that multimerized forms of secreted viral antigen can be more immunogenic and effective in inducing humoral immune response upon administration to a vaccinated subject as compared to monomeric forms. As shown in Figure 3, the viral antigen encoded by the mRNA construct can multimerize after expression, indicating usefulness of the mRNA construct in eliciting an immune response against the virus upon administration to a subject.
ELISA. The quantity of mRNA-encoded viral peptide or protein expressed in cell culture supernatant was determined by ELISA. Particularly, to perform the ELISA assays, microtiter plate wells was coated with 100 μl solution containing 5μg/ml SARS-CoV-2 S Protein RBD, and incubated at 4℃ for 12 hours with closure plate membrane. Next, the plate was washed 3 times in washing buffer. Next, 300 μl of 5%BSA in PBST was added to each well and incubated for 60 minutes at 37℃. Next, the plate was washed 4 times in washing buffer. Next, culture supernatant samples and SARS-CoV-2 S protein RBD standards were diluted in washing buffer and 100 μl of suitably diluted samples and standards were added to the relevant wells in triplicates. Next, the wells were incubated for 60 minutes at 37℃, and washed 3 times in washing buffer. Next, 100 μL of rabbit anti-SARS-CoV-2 S protein antibody was added to each well of plate. Next, the plate was covered and incubated for 60 minutes at 37℃, and washed 3 times in washing buffer. Next, 100 μl of diluted HRP-conjugated anti-Rabbit antibody was added to each well, and incubated for 1 hour at 37℃, and washed 3 times in washing buffer. Next, 100 μl of TMB substrate solution was added to each well, incubated at room temperature (and in the dark if required) for approximately 10 min. Next, 100 μL of Stop Solution was added to each well, and gently and thoroughly mixed. Next, a Molecular Devices plate reader was used to read ODs at 450/620 nm subtracted for detection.
Figure 4 shows an exemplary ELISA analysis measuring protein concentrations (ng/mL) of mRNA-encoded SARS-CoV-2 S protein RBD in culture supernatant of cells transfected with two mRNA constructs, designated as “RBD sample 1” and “RBD sample 2” respectively. BSA was used as a negative control for ELISA. This study further demonstrated that cells transfected with the mRNA constructs expressed and secreted the encoded viral antigen at satisfactory levels, as quantified by ELISA.
Figure 8 shows an exemplary ELISA analysis measuring protein concentrations (ng/ML) of mRNA-encoded S protein RBD of SARS-CoV-2 or mRNA-encoded S protein RBD of the SARS-CoV-2 B. 1.351 variant (sample 4) in culture supernatant of cells transfected with the mRNA constructs. Particularly, the mRNA construct encoding the SARS-CoV-2 RBD fragment is the same as in the sample designated as “RBD sample 2” as shown in Figure 4. As shown in Figure 8, the B. 1.351 variant S protein RBD (sample 4) was expressed at a level comparable to that of the SARS-CoV-2 S protein RBD.
7.3 Example 3. Production of neutralizing antibodies by mice vaccinated with mRNA containing LNP
BALB/c mice were vaccinated by intramuscular injection of 100 μL of LNP formulation containing 10 μg of mRNA encoding a SARS-CoV-2 S protein RBD (RBD sample 1) , and blood was collected from tail veins on day 7, 14, 21 and 28 post-vaccination, respectively. A group of vaccinated mice were also boosted by receiving a second intramuscular injection of the same dose of LNP formulation containing the mRNA 14 days after the first injection, and blood was collected from tail veins on day 7, 14, 21 and 28 after the second boosting injection. The 50%plaque reduction neutralization titer (PRNT 50) values of the collected mouse serum were determined to evaluate the production of neutralizing antibody by the vaccinated animals.
PRNT assays. To perform the plaque reduction neutralization titer (PRNT) assays, the serum sample or solution of antibody to be tested was diluted and mixed with a viral suspension. The mixture was then incubated to allow the antibody to react with the virus. Next, the mixture was poured over a confluent monolayer of host cells. The surface of the cell layer was covered in a layer of agarose or carboxymethyl cellulose to prevent the virus from spreading indiscriminately. The concentration of plaque forming units (PFU) can be estimated by the number of plaques (regions of infected cells) formed a few days later. Depending on the virus, the plaque forming units can be measured by microscopic observation, fluorescent antibodies or specific dyes that react with infected cells. The concentration of serum to reduce the number of plaques by 50%compared to the serum free virus gives the measure of how much antibody is present or how effective it is. This measurement is denoted as the PRNT 50 value (or simply the NT 50 value) .
Particularly, in this study, mouse serum collected as described above were heat inactivated at 55℃ for 30 min and then serially diluted to 1: 50, 1: 100, 1: 200, 1: 400, and 1: 800 in PBS. Equal volume of PBS containing 100 PFU of SARS-CoV-2 or SARS-CoV-2 B. 1.351 pseudovirus was added to each serum dilution. Each mixture was incubated at 37℃ for 30 min, added to confluent cultures of Vero E6 monolayers, and allowed them to incubate at 37℃ for 60 minutes. The cell monolayers were covered with 4 ml of 0.8%agarose melted in standard Vero E6 cell medium, and plaques were resolved the with neutral red staining 2 days later. The PRNT 50 values were then calculated and plotted in Figure 5. Particularly, Y axis shows the reciprocal of PRNT 50 values (i.e., 1/PRNT 50) . X-axis shows the group of animals as follows: in Figure 5 “RBD” denotes mice receiving only the first injection and the “RBD-B” denotes mice receiving the first and the boosting injection; “Control” denotes a group of mice received intramuscular injection of 100μl LNP formulation without mRNA and boosted with the same dose of blank LNP 14 days later. As shown in Figure 5, animals vaccinated with the therapeutic mRNA-containing LNP produced neutralizing antibodies that significantly reduced infection of cells by SARS-CoV-2. This study demonstrated that the present therapeutic mRNA-containing LNP composition can be used for treating, managing or preventing infection by the coronavirus SARS-CoV-2.
7.4 Example 4. Production of neutralizing antibodies by mice vaccinated with mRNA containing LNP -comparison study
BALB/c mice were vaccinated by intramuscular injection of 100 μL of LNP formulation containing 2 μg of mRNA encoding a SARS-CoV-2 S protein RBD (RBD-WT) , SARS-CoV-2 B. 1.351 S protein RBD (RBD-SA) , or PBS and blood was collected from tail veins on day 7, 14, 21 and 28 post-vaccination, respectively. A group of vaccinated mice were also boosted by receiving a second intramuscular injection of the same dose of LNP formulation containing the mRNA 14 days after the first injection, and blood was collected from tail veins on day 7, 14, 21 and 28 after the second boosting injection. The 50%neutralization titer (NT 50) values of the collected mouse serum were determined to evaluate the production of neutralizing antibody by the vaccinated animals.

As shown in Figure 10, animals vaccinated with LNP enclosing therapeutic mRNA encoding either SARS-CoV-2 S protein RBD or the SARS-CoV-2 B. 1.351 S protein RBD of sample 4 both produced neutralizing antibodies that significantly reduced infection of cells by SARS-CoV-2 or the SARS-CoV-2 B. 1.351 variant. This study demonstrated that the present therapeutic mRNA-containing LNP composition can be used for treating, managing or preventing infection by the coronavirus SARS-CoV-2 or a variant thereof.
7.5 Example 5: Study of correlation between RBD expression in mice and mRNA contents of mRNA-LNP samples
The following experiment was performed to establish a method for detecting RBD expression in animals in response to a finished coronavirus SARS-CoV-2 mRNA vaccine product, so as to explore the correlation between the RBD expression and the mRNA contents in the finished product.
Animal grouping and dosing information were as follows:
Experimental animals, ICH mice, were administrated with different test substances by intravenous injectionaccording to the table above. 6 hours after the administration, blood was collected from the heart after deep carbon dioxide anesthesia. After standing at room temperature for about 30 min, the serum was separated (4℃, 8000 rpm (5724 g) , 10 min) , sub packaged (in triplicate, each larger than 110 ul; if it was not able to guarantee that all of the three aliquots met the requirement, at least two of them would do, and the blood volume per tube was marked) , and stored at -80℃in a refrigerator. Serum samples were collected from the remaining 10 blank mice, mixed well and then dispensed into small tubes.
The RBD expression in the serum samples was detected by ELISA method as follows:
All the samples and reagents were recovered to room temperature before use.
1) 100 μL of ACE2 coating stock solution was added to the ELISA plate, and the plate was sealed with a sealing membrane, and incubated at 4 ℃ for 15 hours.
2) The liquid in the wells was discarded, and the plate was washed with a washing buffer for 3 times, 300 μL/well, and soaked for 2 min each time.
3) 300 μL/well of blocking solution was added, and the plate was sealed with a sealing membrane, and incubated at 37 ℃ for 1 hour.
4) The liquid in the wells was discarded, and the plate was washed with a washing buffer for 3 times, 300 μL/well, and soaked for 2 min each time.
5) 100 μL of diluted samples to be tested and a standard were added to the ELISA plate, and the plate was sealed with a sealing membrane, and incubated at 37 ℃ for 1 hour.
6) The liquid in the wells was discarded, and the plate was washed with a washing buffer for 3 times, 300 μL/well, and soaked for 2 min each time.
7) 100 μL of primary antibody stock solution was added to each well of the plate, and the plate was covered with a sealing membrane, and incubated at 37 ℃ for 1 hour.
8) The liquid in the wells was discarded, and the plate was washed with a washing buffer for 3 times, 300 μL/well, and soaked for 2 min each time.
9) 100 μL of HRP secondary antibody stock solution was added to each well of the plate, and the plate was covered with a sealing membrane, and incubated at 37 ℃ for 1 hour.
10) The liquid in the wells was discarded, and the plate was washed with a washing buffer for 3 times, 300 μL/well, and soaked for 2 min each time.
11) 100 μL of TMB substrate solution was added to each microwell, and the plate was incubated at room temperature, protected from the light, for about 5 min.
12) 100 μL of ELISA stop solution was added to each microwell.
13) The result was determined by using a multifunctional microplate reader, where the detection wavelengths were set as 450 nm and 620 nm, a Curve Fit/5-parameter regression model was set for the Standard Curve, and the Dilution Factor of the test samples was set as 2, while standard curve and sample settings being performed (the template settings can be set before the start of the reading) , and where the absorption values were determined.
14) The result was calculated automatically via a software by using a 5-parameter regression model of the protein concentration (X) of the protein standard and its corresponding fluorescence value (Y) , so as to calculate and obtain the protein concentrations (Unk-dilution/AdjResult) in the samples.
The detection results of the RBD contents in the serum samples of the experimental animals were shown in Figure 6 and Table 6. Among all mouse serum samples, no RBD concentration was detected in the “blank serum” sample. It was observed that there was a significant dose-dependence between 1 ug and 5 ug mRNA, and the expressed RBD contents were 0.14-2.18 ng/mL.

7.6 Example 6: Antigen immunogenicity analysis
The purpose of the following experiment was to evaluate the immunogenicity of the mRNA molecular liposome (RBD mRNA-LNP) loaded with the SARS-CoV-2 coronavirus S-RBD protein of the present invention.
The number of animals in each group and the detailed immunization routes, doses and schedules were shown in the table below. Experimental animals, BALB/c mice, received the test antigen (10 μg/50 μL per mouse) via a single point intramuscular injection on the right hind limb on day 0. A same dose of the test vaccine was vaccinated again on day 14. The detailed administration methods, dosing amounts and administration routes were as follows:
Note: a: The day of the first immunization was defined as day 0.
Before the first immunization, 4 mice were randomly selected to collect blood to prepare serum samples (above 150 μL) , and the serum samples were collected without anticoagulants for monitoring, as shown in the following table.
There were 52 samples in total as follows: 4 serum samples collected before the first immunization; 16 serum samples collected 14 days after the first immunization; 16 serum samples collected 21 days after the first immunization; and 16 serum samples collected 28 days after the first immunization, respectively. After the serum collection was completed, the coronavirus RBD IgG titers were detected together. In this experiment, a "Mouse Anti-New Coronavirus (2019-nCoV) S-RBD Protein IgG Antibody Detection Kit" developed by Wantai BioPharm was used for IgG titer detection. The test serum samples were diluted in a 10-fold gradient starting from 1: 10 with a sample diluent, and shaken gently to mix well. 100 μL of each of the diluted samples, the negative control and the positive control was added to each well. The plate was sealed with a sealing membrane. The sealing membrane was cut off at 37℃ for 30 min, and the plate was washed for 5 times, 300 μL each time, and dried at the last time. 100 μL of ELISA reagent was added to each well, except for blank wells. The sealing membrane was cut off at 37℃ for 30 min, and the plate was washed for 5 times, 300 μL each time. 50 mL of each of color developer A and B was added to each well, shaken gently to mix well, and developed at 37℃, protected from the light, for 15 min. 50 μL of the stop solution was added to each well, and mixed well in a gentle manner. The result was measured within 10 min. The wavelength of the microplate reader was set at 450 nm. The maximum dilution factor for which the detection result was positive was selected, and Titer result was the OD value of the positive maximum dilution factor/0.1*corresponding dilution factor.
Specifically, the mice were immunized with a single dose (10 μg) of the mRNA vaccine on day 0, and a booster dose (10 μg) was given on day 14. The anti-S-RBD IgG antibody levels in the mouse serum samples were detected 14, 21, and 29 days after the immunization. The results were shown in Figure 7. In the group of mice vaccinated with mRNA-LNP, one week after the second immunization, the specific IgG titer increased from about 1/900 on day 14 to 1/70,000 on day 21 and maintained at the same level on day 29. In contrast, neither of the empty liposome and PBS control groups had RBD-specific IgG expression. This result clearly showed that the vaccine product described in the present invention had strong immunogenicity and can specifically induce the production of related antibodies to achieve the effect of controlling or preventing the infection of the coronavirus SARS-CoV-2.
7.7 Example 7: Antigen immunogenicity analysis -comparison study
The purpose of the following study was to compare immunogenicity of LNP species loaded with mRNA encoding the SARS-CoV-2 S protein RBD (RBD-WT) and mRNA (Sample 3 or Sample 4) encoding the SARS-CoV-2 B. 1.351 S protein RBD (RBD-SA) , respectively.
The number of animals in each group and the detailed immunization routes, doses and schedules were shown in the table below. Experimental animals, BALB/c mice, received the test antigen (2 μg/50 μL per mouse) via a single point intramuscular injection on the right hind limb on day 0. A same dose of the test vaccine was vaccinated again on day 14. The detailed administration methods, dosing amounts and administration routes were as follows:
Note: a: The day of the first immunization was defined as day 0.
The serum samples were collected without anticoagulants for monitoring, as shown in the following table.
There were 90 samples in total as follows: 30 serum samples collected 14 days after the first immunization; 30 serum samples collected 21 days after the first immunization; and 30 serum samples collected 28 days after the first immunization, respectively. After the serum collection was completed, the coronavirus RBD IgG titers were detected together. In this experiment, a "Mouse Anti-New Coronavirus (2019-nCoV) S-RBD Protein IgG Antibody Detection Kit" developed by Wantai BioPharm was used for IgG titer detection. The test serum samples were diluted in a 10-fold gradient starting from 1: 10 with a sample diluent, and shaken gently to mix well. 100 μL of each of the diluted samples, the negative control and the positive control was added to each well. The plate was sealed with a sealing membrane. The sealing membrane was cut off at 37℃ for 30 min, and the plate was washed for 5 times, 300 μL each time, and dried at the last time. 100 μL of ELISA reagent was added to each well, except for blank wells. The sealing membrane was cut off at 37℃ for 30 min, and the plate was washed for 5 times, 300 μL each time. 50 mL of each of color developer A and B was added to each well, shaken gently to mix well, and developed at 37℃, protected from the light, for 15 min. 50 μL of the stop solution was added to each well, and mixed well in a gentle manner. The result was measured within 10 min. The wavelength of the microplate reader was set at 450 nm. The maximum dilution factor for which the detection result was positive was selected, and Titer result was the OD value of the positive maximum dilution factor/0.1*corresponding dilution factor.
Figure 9A and 9B show the level of IgG antibodies detected by ELISA. Firstly, different forms of RBD protein are coated on the ELISA plate, and then the mouse serum and the RBD protein are combined, and the binding value of the serum and the protein is detected by the HRP-coupled secondary antibody to calculate the antibody level. It can be concluded from figure 9A and 9B that the South African vaccine can stimulate better antibody levels, not weaker or even stronger than the wild type vaccine.
Specifically, the mice were immunized with a single dose (10 μg) of the mRNA vaccine on day 0, and a booster dose (10 μg) was given on day 14. The anti-S-RBD IgG antibody levels in the mouse serum samples were detected 14, and 21 days after the immunization by ELISA, and the results are shown in Figures 9A and 9B. Particularly, in a first ELISA assay, the anti-S-RBD IgG antibody levels were measured using recombinant SARS-CoV-2 S protein RBD immobilized on the ELISA plate (Figure 9A) , and in a second ELISA assay, the anti-S-RBD IgG antibody levels were measured using recombinant SARS-CoV-2 B. 1.351 S protein RBD (Figure 9B) . The results showed S-RBD specific antibodies produced by immunized animals were capable of binding to the S protein RBD derived from both SARS-CoV-2 coronavirus and the B. 1.351 variant. Furthermore, the antibody titers in animals immunized with the two species of mRNA-LNP were at comparable levels. Particularly, animals immunized with mRNA-LNP of Sample 4 encoding the B. 1.351 variant S-RBD protein produced higher antibody titers (FIG. 9A Day 14; FIG. 9B Days 14 and 21) or equivalent antibody titers (FIG. 9A Day 21) comparing to animals immunized with mRNA-LNP encoding SARS-CoV-2 S-RBD. This study demonstrated that the present therapeutic mRNA-containing LNP composition can be used for treating, managing or preventing infection by the coronavirus SARS-CoV-2 or a variant thereof.
