FIELD OF THE INVENTION
-
This invention relates to antigen-binding molecules that bind cell surface receptors involved in regulation of the immune response. It relates to antibodies for use in stimulating a patient's immune system, especially the effector T cell response, and has applications in the field of immuno-oncology, especially treatment of tumours.
BACKGROUND
-
An adaptive immune response involves activation, selection, and clonal proliferation of two major classes of lymphocytes termed T cells and B cells. After encountering an antigen, T cells proliferate and differentiate into antigen-specific effector cells, while B-cells proliferate and differentiate into antibody-secreting cells. T cell activation is a multi-step process requiring several signalling events between the T cell and an antigen-presenting cell (APC). For T cell activation to occur, two types of signals must be delivered to a resting T cell. The first type is mediated by the antigen-specific T cell receptor (TCR), and confers specificity to the immune response. The second signal, a costimulatory signal, regulates the magnitude of the response and is delivered through accessory receptors on the T cell.
-
A primary costimulatory signal is delivered through the activating CD28 receptor upon engagement of its ligands B7-1 or B7-2. In contrast, engagement of the inhibitory CTLA-4 receptor by the same B7-1 or B7-2 ligands results in attenuation of a T cell response. Thus, CTLA-4 signals antagonise costimulation mediated by CD28. At high antigen concentrations, CD28 costimulation overrides the CTLA-4 inhibitory effect. Temporal regulation of the CD28 and CTLA-4 expression maintains a balance between activating and inhibitory signals and ensures the development of an effective immune response, while safeguarding against the development of autoimmunity.
-
Programmed death-1 (PD-1) is a 50-55 kDa type I transmembrane receptor that is a member of the CD28 family. PD-1 is involved in the regulation of T-cell activation and is expressed on T cells, B cells, and myeloid cells. Two ligands for PD-1, PD ligand 1 (PD-L1) and ligand 2 (PD-L2) have been identified and have costimulatory features.
-
Programmed cell death 1 ligand 1 (PD-L1), also known as cluster of differentiation (CD274) or B7 homolog 1 (B7-H1), is a member of the B7 family that modulates activation or inhibition of the PD-1 receptor. The open reading frame of PD-L1 encodes a putative type 1 transmembrane protein of 290 amino acids, which includes two extracellular Ig domains (an N-terminal V-like domain and an Ig C-like domain), a hydrophobic transmembrane domain and a cytoplasmic tail of 30 amino acids. The 30 amino acid intracellular (cytoplasmic) domain contains no obvious signalling motifs, but does have a potential site for protein kinase C phosphorylation. The complete amino acid sequence for PD-L1 can be found in NCBI Reference Sequence: NP_054862.1 (SEQ ID NO: 1), which refers to many journal articles [1]. The PD-L1 gene is conserved in chimpanzee, Rhesus monkey, dog, cow, mouse, rat, chicken, and zebrafish. The murine form of PD-L1 bears 69% amino acid identity with the human form of PD-L1, and also shares a conserved structure.
-
In humans, PD-L1 is expressed on a number of immune cell types including activated and anergic/exhausted T cells, on naive and activated B cells, as well as on myeloid dendritic cells (DC), monocytes and mast cells. It is also expressed on non-immune cells including islets of the pancreas, Kupffer cells of the liver, vascular endothelium and selected epithelia, for example airway epithelia and renal tubule epithelia, where its expression is enhanced during inflammatory episodes. PD-L1 expression is also found at increased levels on a number of tumours, such as breast (e.g., triple negative breast cancer and inflammatory breast cancer), ovarian, cervical, colon, colorectal, lung (e.g., non-small cell lung cancer), renal (e.g., renal cell carcinoma), gastric, oesophageal, bladder, hepatocellular cancer, squamous cell carcinoma of the head and neck (SCCHN) and pancreatic cancer, melanoma and uveal melanoma.
-
PD-1/PD-L1 signalling is believed to serve a critical non-redundant function within the immune system by negatively regulating T cell responses. This regulation is involved in T cell development in the thymus, in regulation of chronic inflammatory responses and in maintenance of both peripheral tolerance and immune privilege. It appears that upregulation of PD-L1 may allow cancers to evade the host immune system and, in many cancers, the expression of PD-L1 is associated with reduced survival and an unfavourable prognosis. Therapeutic monoclonal antibodies that are able to block the PD-1/PD-L1 pathway may enhance anti-tumoural immune responses in patients with cancer. Published clinical data suggest a correlation between clinical responses with tumoural membranous expression of PD-L1 and a stronger correlation between lack of clinical responses and a lack of PD-L1 protein localised to the membrane [2, 3]. Thus, PD-L1 expression in tumours or tumour-infiltrating leukocytes is a candidate molecular marker for use in selecting patients for immunotherapy, for example, immunotherapy using anti-PD-L1 antibodies [4]. Patient enrichment based on surface expression of PD-L1 may significantly enhance the clinical success of treatment with drugs targeting the PD-1/PD-L1 pathway. There is also evidence of an ongoing immune response, such as the tumour infiltrating CD8+ T cells, or the presence of signature of cytokine activation, such as IFNγ.
-
Further evidence of PD-L1 expression and correlation to disease will emerge from the numerous ongoing clinical trials. Atezolizumab is the most advanced anti-PD-L1 antibody in development, and Phase II trials showed therapeutic effects in metastatic urothelial carcinoma and NSCLC, particularly in patients with PD-L1+ immune cells in the tumour microenvironment [5, 6]). Recent results from a Phase III trial of 1225 patients with NSCLC showed improved survival in patients taking atezolizumab, compared with chemotherapy, regardless of tumour expression of PD-L1 (Rittmeyer et al., 2017, The Lancet, 389(10066), 255-265).
-
Another member of the CD28 gene family, ICOS (Inducible T cell Co-Stimulator), was identified in 1999 [7]. It is a 55 kDa transmembrane protein, existing as a disulphide linked homodimer with two differentially glycosylated subunits. ICOS is exclusively expressed on T lymphocytes, and is found on a variety of T cell subsets. It is present at low levels on naïve T lymphocytes but its expression is rapidly induced upon immune activation, being upregulated in response to pro-inflammatory stimuli such as on engagement of TCR and co-stimulation with CD28 [8, 9]. ICOS plays a role in the late phase of T cell activation, memory T cell formation and importantly in the regulation of humoral responses through T cell dependent B cell responses [10, 11]. Intracellularly, ICOS binds PI3K and activates the kinases phophoinositide-dependent kinase 1 (PDK1) and protein kinase B (PKB). Activation of ICOS prevents cell death and upregulates cellular metabolism. In the absence of ICOS (ICOS knock-out) or in the presence of anti-ICOS neutralising antibodies there would be a suppression of pro-inflammatory responses.
-
ICOS binds to ICOS ligand (ICOSL) expressed on B-cells and antigen presenting cells (APC) [12, 13]. As a co-stimulatory molecule it serves to regulate TCR mediated immune responses and antibody responses to antigen. The expression of ICOS on T regulatory cells may be important, as it has been suggested that this cell type plays a negative role in immunosurveillance of cancer cells—there is emerging evidence for this in ovarian cancer [14]. Importantly, ICOS expression has been reported to be higher on intratumoural regulatory T cells (TRegs) compared with CD4+ and CD8+ effector cells that are present in the tumour microenvironment. Depletion of TRegs using antibodies with Fc-mediated cellular effector function has demonstrated strong anti-tumour efficacy in a pre-clinical model [15]. Mounting evidence implicates ICOS in an anti-tumour effect in both animal models as well as patients treated with immune-checkpoint inhibitors. In mice deficient in ICOS or ICOSL the anti-tumor effect of anti-CTLA4 therapy is diminished [16] while in normal mice ICOS ligand increases the effectiveness of anti-CTLA4 treatment in melanoma and prostate cancer [17]. Furthermore, in humans a retrospective study of advanced melanoma patients showed increased levels of ICOS following ipilimumab (anti-CTLA4) treatment [18]. In addition, ICOS expression is upregulated in bladder cancer patients treated with anti-CTLA4 [19]. It has also been observed that in cancer patients treated with anti-CTLA4 therapy the bulk of tumour specific IFNγ producing CD4 T-cells are ICOS positive while sustained elevation of ICOS positive CD4 T cells correlates with survival [18, 19, 20].
-
WO2016/120789 described anti-ICOS antibodies and proposed their use for activating T cells and for treating cancer, infectious disease and/or sepsis. A number of murine anti-ICOS antibodies were generated, of which a sub-set were reported to be agonists of the human ICOS receptor. The antibody “422.2” was selected as the lead anti-ICOS antibody and was humanised to produce a human “IgG4PE” antibody designated “H2L5”. H2L5 was reported to have an affinity of 1.34 nM for human ICOS and 0.95 nM for cynomolgus ICOS, to induce cytokine production in T cells, and to upregulate T cell activation markers in conjunction with CD3 stimulation. However, mice bearing implanted human melanoma cells were reported to show only minimal tumour growth delay or increase in survival when treated with H2L5 hIgG4PE, compared with control treated group. The antibody also failed to produce significant further inhibition of tumour growth in combination experiments with ipilimumab (anti-CTLA-4) or pembrolizumab (anti-PD-1), compared with ipilimumab or pembrolizumab monotherapy. Finally, in mice bearing implanted colon cancer cells (CT26), low doses of a mouse cross reactive surrogate of H2L5 in combination with a mouse surrogate of ipilimumab or pembrolizumab only mildly improved overall survival compared with anti-CTL4 and anti-PD1 therapy alone. A similar lack of strong therapeutic benefit was shown in mice bearing implanted EMT6 cells.
-
WO2016/154177 described further examples of anti-ICOS antibodies. These antibodies were reported to be agonists of CD4+ T cells, including effector CD8+ T cells (TEff), and to deplete T regulator cells (TRegs). Selective effects of the antibodies on TEff vs TReg cells were described, whereby the antibodies could preferentially deplete TRegs while having minimal effect on TEffs that express a lower level of ICOS. The anti-ICOS antibodies were proposed for use in treating cancer, and combination therapy with anti-PD-1 or anti-PD-L1 antibodies was described.
-
Although there has been immense progress in the field of immuno-oncology in recent years, current response rates of immuno-oncology drugs remain low. For example, the response rate for the anti-PD-1 antibody nivolumab in melanoma is around 30%, and the response rate for the anti-PD-L1 atezolizumab in its Phase II clinical trial in urothelial carcinoma was around 15% overall in patients regardless of PD-L1 expression or 26% in patients with PD-L1 expressing tumours. Efforts to increase efficacy of immuno-oncology treatment have included combining multiple drugs, for example combinations of antibodies and traditional chemotherapeutic agents or radiation, and the combined use of drugs targeting different immune checkpoint inhibitors. A combination of nivolumab (anti-PD-1) and ipilimumab (anti-CTLA-4) has shown efficacy in previously untreated cases of melanoma, with headline response rates and overall survival being encouraging [21]. However, although combination therapy may generate new or enhanced biological effects in vivo, this carries an associated risk of negative drug interactions and new or worsened side-effects. Immune checkpoint inhibitor therapy is already associated with immune-related adverse events, including neurological events ranging from mild headache to life-threatening encephalitis [22]. Further, on a practical level, treatment regimens involving combinations of multiple therapeutic agents have the drawbacks of complex administration regimens and high cost.
SUMMARY OF THE INVENTION
-
The present invention relates to antigen-binding molecules that comprise multiple antigen-binding sites (“multispecific antigen-binding molecules”), including an antigen-binding site for ICOS and an antigen-binding site for another target antigen, e.g., PD-L1.
-
Both ICOS and PD-L1 are expressed following primary T cell activation. PD-L1 negatively regulates T cell activation, and inhibition of PD-L1 signalling has been clinically validated as an approach to upregulate the T cell immune response against tumour cells. In context, parallel depletion of ICOS-high Tregs and stimulation of ICOS-low effector T cells can enhance T cell activation to promote anti-tumour activity.
-
A multispecific antigen-binding molecule that blocks the negative regulatory activity of PD-L1 on PD1+ T cells and enhances T cell activation by delivering a positive signal through ICOS offers therapeutic potential in treating cancer and other conditions in which it is desirable to upregulate the T cell immune response. The fate of T cells in the tumour microenvironment and in tumour-draining lymph nodes is influenced by a balance of inhibitory and activatory receptors, and a molecule that binds and inhibits PD-L1 while acting as an ICOS agonist may effectively turn a negative signal (from the inhibitory PD-L1 receptor) into a positive signal (from the ICOS co-activatory receptor). The immune synapse between a T cell and an antigen-presenting cell (APC) or tumour cell can be envisaged as a receptor-dense space in which the balance of receptor occupancy determines signalling within the T cell, this receptor occupancy being governed by the identity and concentration of receptors being presented on the surface of the engaging APC/tumour cell. A multispecific molecule bearing a binding site for ICOS and a binding site for PD-L1 may act directly at this immune synapse to change the balance of signals received by T cells, shifting the balance towards activation of TEffs. Combination of anti-PD-L1 and anti-ICOS in one multispecific antigen-binding molecule, rather than separate antigen-binding molecules, provides a single agent that can act as a molecular switch. The multispecific molecule may cross-link ICOS and PD-L1 on different cells (FIG. 1 ).
-
In addition to binding its two cognate antigens, a multi-specific antigen-binding molecule may incorporate other moieties such as antibody effector regions to recruit cell-killing functions, which may further tip the immune balance towards T cell activation and killing of cancer cells, e.g., via depletion of TRegs which highly express ICOS on the cell surface and/or depletion of cancer cells expressing PD-L1. A bispecific antibody binding to ICOS and PD-L1 may trigger ADCC towards PD-L1+ immunosuppressive cells (e.g., MDSC, tumour cells) and/or ADCC towards ICOS+ immunosuppressive cells (e.g., Tregs).
-
A multispecific antigen-binding molecule according to the present invention may be an antibody (e.g., a bispecific or dual-binding antibody) that binds ICOS and another target antigen. Numerous multispecific antibody formats are possible, and many examples are provided herein. The antibody may be bivalent for both target antigens. For example, the antibody may be a FIT-Ig comprising two ICOS-binding Fab domains and two PD-L1 binding domains (e.g., as illustrated in FIG. 2 ). Alternatively, the antibody may be a mAb2 comprising two ICOS-binding Fab domains and an Fc region comprising two binding sites for PD-L1 (i.e., a PD-L1 binding Fcab), as illustrated in FIG. 3 . Examples of ICOS antibodies and PD-L1 antibodies sequences, including VH and VL domain sequences, are set out herein and may be included in the multispecific antibodies.
-
A multispecific antigen-binding molecule that binds ICOS and PD-L1 may increase response rates of tumours that are already responsive to PD-L1 or ICOS monotherapy, increasing the proportion of patients in whom an anti-tumour response is observed and potentially improving the level of response, reducing tumour growth and extending survival compared with monotherapy. Some tumours are unresponsive to either anti-ICOS or anti-PD-L1 antibody, but may respond to a multispecific antibody that binds ICOS and PD-L1. Anti-ICOS/anti-PD-L1 bispecific binding molecules may also be used for inducing long term memory to antigens, e.g., tumour antigens, thereby providing protection against tumour regrowth. Thus, the multispecific approach described here offers advantages in improving response rates, duration of response, and patient survival, in the context of cancer therapy. Furthermore, a multispecific antigen-binding molecule can be administered to patients using simpler treatment regimens compared with multiple separate formulations of different therapeutic agents.

As used herein, the term “antibody” encompasses intact polyclonal antibodies, intact monoclonal antibodies, antibody fragments (such as Fab, Fab′, F(ab′)2, and Fμ fragments), single chain Fμ (scFv) mutants, multispecific antibodies such as bispecific antibodies (including dual binding antibodies), chimeric antibodies, humanized antibodies, human antibodies, fusion proteins comprising an antigen determination portion of an antibody, and any other modified immunoglobulin molecule comprising an antigen recognition site so long as the antibodies exhibit the desired biological activity. The term “antibody” can also refer to a Y-shaped glycoprotein with a molecular weight of approximately 150 kDa that is made up of four polypeptide chains: two light (L) chains and two heavy (H) chains. There are five types of mammalian Ig heavy chain isotypes denoted by the Greek letters alpha (α), delta (δ), epsilon (ε), gamma (γ), and mu (μ). The type of heavy chain defines the class of antibody, i.e., IgA, IgD, IgE, IgG, and IgM, respectively. The γ and a classes are further divided into subclasses on the basis of differences in the constant domain sequence and function, e.g., IgG1, hIgG2, mIgG2A, mIgG2B, IgG3, IgG4, IgA1 and IgA2. In mammals there are two types of immunoglobulin light chains, A and K. The “variable region” or “variable domain” of an antibody refers to the amino-terminal domains of the heavy or light chain of the antibody. The variable domains of the heavy chain and light chain may be referred to as “VH” and “VL”, respectively. These domains are generally the most variable parts of the antibody (relative to other antibodies of the same class) and contain the antigen binding sites.
-
The antibodies described herein may be oligoclonal, polyclonal, monoclonal (including full-length monoclonal antibodies), camelised, chimeric, CDR-grafted, multi-specific, bi-specific (including dual-binding antibodies), catalytic, chimeric, humanized, fully human, anti-idiotypic, including antibodies that can be labelled in soluble or bound form as well as fragments, variants or derivatives thereof, either alone or in combination with other amino acid sequences provided by known techniques. An antibody may be from any species. Antibodies described herein can be naked or conjugated to other molecules such as toxins, radioisotopes, etc.
-
The term “antigen binding domain,” “antigen binding region,” “antigen binding fragment,” and similar terms refer to that portion of an antibody which comprises the amino acid residues that interact with an antigen and confer on the binding agent its specificity and affinity for the antigen (e.g., the complementarity determining regions (CDRs)). The antigen binding region can be derived from any animal species, such as rodents (e.g., rabbit, rat or hamster) and humans. Preferably, the antigen binding region will be of human origin. Antigen binding fragments described herein can include single-chain Fvs (scFv), single-chain antibodies, single domain antibodies, domain antibodies, Fv fragments, Fab fragments, F(ab′) fragments, F(ab′)2 fragments, antibody fragments that exhibit the desired biological activity, disulfide-stabilised variable region (dsFv), dimeric variable region (diabody), anti-idiotypic (anti-Id) antibodies (including, e.g., anti-Id antibodies to antibodies), intrabodies, linear antibodies, single-chain antibody molecules and multispecific antibodies formed from antibody fragments and epitope-binding fragments of any of the above. In particular, antibodies and antibody fragments described herein can include immunoglobulin molecules and immunologically active fragments of immunoglobulin molecules, i.e., molecules that contain an antigen-binding site. Digestion of antibodies with the enzyme, papain, results in two identical antigen-binding fragments, known also as “Fab” fragments, and a “Fc” fragment, having no antigen-binding activity but having the ability to crystallize. “Fab” when used herein refers to a fragment of an antibody that includes one constant and one variable domain of each of the heavy and light chains. The term “Fc region” herein is used to define a C-terminal region of an immunoglobulin heavy chain, including native-sequence Fc regions and variant Fc regions. The “Fc fragment” refers to the carboxy-terminal portions of both H chains held together by disulfides. The effector functions of antibodies are determined by sequences in the Fc region, the region which is also recognized by Fc receptors (FcR) found on certain types of cells. Digestion of antibodies with the enzyme, pepsin, results in the a F(ab′)2 fragment in which the two arms of the antibody molecule remain linked and comprise two-antigen binding sites. The F(ab′)2 fragment has the ability to crosslink antigen. “Fv” when used herein refers to the minimum fragment of an antibody that retains both antigen-recognition and antigen-binding sites. This region consists of a dimer of one heavy and one light chain variable domain in tight, non-covalent or covalent association. It is in this configuration that the three CDRs of each variable domain interact to define an antigen-binding site on the surface of the VH-VL dimer. Collectively, the six CDRs confer antigen-binding specificity to the antibody. However, even a single variable domain (or half of an Fv comprising only three CDRs specific for an antigen) has the ability to recognize and bind antigen, although at a lower affinity than the entire binding site.
-
The term “monoclonal antibody” as used herein refers to an antibody obtained from a population of substantially homogeneous antibodies, i.e., the individual antibodies comprising the population are identical except for possible naturally occurring mutations and/or post-translation modifications (e.g., isomerizations, amidations) that may be present in minor amounts. Monoclonal antibodies are highly specific, and are directed against a single antigentic determinant or epitope. In contrast, polyclonal antibody preparations typically include different antibodies directed against different antigenic determinants (or epitopes). The term “monoclonal antibody” as used herein encompasses both intact and full-length monoclonal antibodies as well as antibody fragments (such as Fab, Fab′, F(ab′)2, Fv), single chain (scFv) mutants, fusion proteins comprising an antibody portion, and any other modified immunoglobulin molecule comprising an antigen recognition site. Furthermore, “monoclonal antibody” refers to such antibodies made in any number of ways including, but not limited to, hybridoma, phage selection, recombinant expression, and transgenic animals. The monoclonal antibodies herein can include “chimeric” antibodies (immunoglobulins) in which a portion of the heavy and/or light chain is identical with or homologous to corresponding sequences in antibodies derived from a particular species or belonging to a particular antibody class or subclass, while the remainder of the chain(s) is(are) identical with or homologous to corresponding sequences in antibodies derived from another species or belonging to another antibody class or subclass, as well as fragments of such antibodies that exhibit the desired biological activity.
-
The term “humanized antibody” refers to a subset of chimeric antibodies in which a “hypervariable region” from a non-human immunoglobulin (the donor antibody) replaces residues from a hypervariable region in a human immunoglobulin (recipient antibody). In general, a humanized antibody will include substantially all of at least one, and typically two, variable domains, in which all or substantially all of the hypervariable loops correspond to those of a non-human immunoglobulin sequence, and all or substantially all of the framework regions are those of a human immunoglobulin sequence, although the framework regions may include one or more substitutions that improve antibody performance, such as binding affinity, isomerization, immunogenicity, etc.
-

-
The term “hypervariable region”, “CDR region” or “CDR” refers to the regions of an antibody variable domain which are hypervariable in sequence and/or form structurally defined loops. Generally, antigen binding sites of an antibody include six hypervariable regions: three in the VH (CDRH1, CDRH2, CDRH3), and three in the VL (CDRL1, CDRL2, CDRL3). These regions of the heavy and light chains of an antibody confer antigen-binding specificity to the antibody. CDRs may be defined according to the Kabat system (see Kabat, E. A. et al., 1991, “Sequences of Proteins of Immunological Interest”, 5th edit., NIH Publication no. 91-3242, U.S. Department of Health and Human Services). Other systems may be used to define CDRs, which as the system devised by Chothia et al (see Chothia, C. & Lesk, A. M., 1987, “Canonical structures for the hypervariable regions of immunoglobulins”, J. Mol. Biol., 196, 901-917) and the IMGT system (see Lefranc, M. P., 1997, “Unique database numbering system for immunogenetic analysis”, Immunol. Today, 18, 50). An antibody typically contains 3 heavy chain CDRs and 3 light chain CDRs. The term CDR or CDRs is used here to indicate one or several of these regions. A person skilled in the art is able to readily compare the different systems of nomenclature and determine whether a particular sequence may be defined as a CDR.
-
A “human antibody” is an antibody that possesses an amino-acid sequence corresponding to that of an antibody produced by a human and/or has been made using any of the techniques for making human antibodies and specifically excludes a humanized antibody comprising non-human antigen-binding residues. The term “specifically binds to” refers to measurable and reproducible interactions such as binding between a target and an antibody, which is determinative of the presence of the target in the presence of a heterogeneous population of molecules including biological molecules. For example, an antibody that specifically binds to a target (which can be an epitope) is an antibody that binds this target with greater affinity, avidity, more readily, and/or with greater duration than it binds to other targets. In one embodiment, the extent of binding of an antibody to an unrelated target is less than about 10% of the binding of the antibody to the target as measured, e.g., by a radioimmunoassay (RIA).
-
An antibody or a fragment thereof that specifically binds to a hPD-L1 antigen may be cross-reactive with related antigens. Preferably, an antibody or a fragment thereof that specifically binds to a hPD-L1 antigen does not cross-react with other antigens (but may optionally cross-react with PD-L1 of a different species, e.g., rhesus, or murine). An antibody or a fragment thereof that specifically binds to a hPD-L1 antigen can be identified, for example, by immunoassays, BIAcore™, or other techniques known to those of skill in the art. An antibody or a fragment thereof binds specifically to a PD-L1 antigen when it binds to a hPD-L1 antigen with higher affinity than to any cross-reactive antigen as determined using experimental techniques, such as radioimmunoassays (RIA) and enzyme-linked immunosorbent assays (ELISAs). Typically, a specific or selective reaction will be at least twice background signal or noise and more typically more than 10 times (such as more than 15 times, more than 20 times, more than 50 times or more than 100 times) background. See, e.g., Paul, ed., 1989, Fundamental Immunology Second Edition, Raven Press, New York at pages 332-336 for a discussion regarding antibody specificity

Such pharmaceutical carriers can be sterile liquids, such as water and oils, including those of petroleum, animal, vegetable or synthetic origin, such as peanut oil, soybean oil, mineral oil, sesame oil and the like. Water is a preferred carrier when the pharmaceutical composition is administered intravenously. Saline solutions and aqueous dextrose and glycerol solutions can also be employed as liquid carriers, particularly for injectable solutions.
-
The term “chemotherapeutic agent” or “chemotherapy” refers to a therapeutic agent whose primary purpose is to destroy cancer cells, typically by interfering with the tumour cell's ability to grow or multiply. There are many different types of chemotherapeutic agents, with more than 50 approved chemotherapy drugs available. Chemotherapeutic drugs can be classified based on how they work. Alkylating drugs kill cancer cells by directly attacking DNA, the genetic material of the genes. Cyclophosphamide is an alkylating drug. Antimetabolites interfere with the production of DNA and keep cells from growing and multiplying. An example of an antimetabolite is 5-fluorouracil (5-FU). Anti-tumour antibiotics are made from natural substances such as fungi in the soil. They interfere with important cell functions, including production of DNA and cell proteins. Doxorubicin and bleomycin belong to this group of chemotherapy drugs. Plant alkaloids prevent cells from dividing normally. Vinblastine and vincristine are plant alkaloids obtained from the periwinkle plant. Steroid hormones slow the growth of some cancers that depend on hormones. For example, tamoxifen is used to treat breast cancers that depend on the hormone estrogen for growth. DNA damage response (DDR) inhibitors, such as PARP inhibitors, block DNA repair mechanisms following single or double stranded breaks.

For example, but not by way of limitation, a hPD-L1 polypeptide, a fragment of a hPD-L1 polypeptide, or a hPD-L1 antibody may be chemically modified, e.g., by glycosylation, acetylation, pegylation, phosphorylation, amidation, derivatization by known protecting/blocking groups, proteolytic cleavage, 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 peptide or polypeptide. A derivative of a hPD-L1 polypeptide, a fragment of a hPD-L1 polypeptide, or a hPD-L1 antibody may be chemically modified by chemical modifications using techniques known to those of skill in the art, including, but not limited to specific chemical cleavage, acetylation, formulation, metabolic synthesis of tunicamycin, etc. Further, a derivative of a hPD-L1 polypeptide, a fragment of a hPD-L1 polypeptide, or a hPD-L1 antibody may contain one or more non-classical amino acids.

An “effective amount” refers to an amount effective, at dosages and for periods of time necessary, to achieve the desired effect, including a therapeutic or prophylactic result. A “therapeutically effective amount” refers to the minimum concentration required to effect a measurable improvement or prevention of a particular disorder. A therapeutically effective amount herein may vary according to factors such as the disease state, age, sex, and weight of the patient, and the ability of the antibody to elicit a desired response in the individual. A therapeutically effective amount is also one in which toxic or detrimental effects of the antibody are outweighed by the therapeutically beneficial effects. A “prophylactically effective amount” refers to an amount effective, at the dosages and for periods of time necessary, to achieve the desired prophylactic result. In some embodiments, the effective amount of an antibody of the invention is from about 0.1 mg/kg (mg of antibody per kg weight of the subject) to about 100 mg/kg. In certain embodiments, an effective amount of an antibody provided therein is about 0.1 mg/kg, about 0.5 mg/kg, about 1 mg/kg, 3 mg/kg, 5 mg/kg, about 10 mg/kg, about 15 mg/kg, about 20 mg/kg, about 25 mg/kg, about 30 mg/kg, about 35 mg/kg, about 40 mg/kg, about 45 mg/kg, about 50 mg/kg, about 60 mg/kg, about 70 mg/kg, about 80 mg/kg about 90 mg/kg or about 100 mg/kg (or a range therein).

-
The term “epitope” as used herein refers to a localized region on the surface of an antigen, such as hPD-L1 polypeptide or hPD-L1 polypeptide fragment, 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, preferably a mammal, and most preferably in 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 specifically binds as determined by any method well known in the art, for example, by the immunoassays described herein. Antigenic epitopes need not necessarily be immunogenic. Epitopes usually 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. A region of a polypeptide contributing to an epitope may be contiguous amino acids of the polypeptide or the epitope may come together from two or more non-contiguous regions of the polypeptide. The epitope may or may not be a three-dimensional surface feature of the antigen. In certain embodiments, a hPD-L1 epitope is a three-dimensional surface feature of a hPD-L1 polypeptide (e.g., in a trimeric form of a hPD-L1 polypeptide). In other embodiments, a hPD-L1 epitope is linear feature of a hPD-L1 polypeptide (e.g., in a trimeric form or monomeric form of the hPD-L1 polypeptide). Antibodies provided herein may specifically bind to an epitope of the monomeric (denatured) form of hPD-L1, an epitope of the trimeric (native) form of hPD-L1, or both the monomeric (denatured) form and the trimeric (native) form of hPD-L1. In specific embodiments, the antibodies provided herein specifically bind to an epitope of the trimeric form of hPD-L1 but do not specifically bind the monomeric form of hPD-L1.

See, also, Remington's Pharmaceutical Sciences (1990) Mack Publishing Co., Easton, Pa., which is hereby incorporated by reference in its entirety.
-
As used herein, the term “fixed” or “fixation” refers to a chemical process by which biological tissues are preserved from decay, to prevent autolysis or putrefaction. In general, fixation involves exposing the tissue to chemical compounds such as alcohols or aldehydes such as formaldehyde to terminate ongoing biochemical reactions. In some instances, fixation may also increase the mechanical strength or stability of the treated tissues. The term “unfixed” refers to a tissue that has not been subjected to a chemical process to prevent tissue decay. As used herein, the term “surface expressed” means that the protein is embedded in or spans a cell membrane or is associated with a protein that is embedded in or spans a cell membrane (i.e., a membrane associated protein). In one embodiment, a surface expressed protein includes one or more transmembrane domains. In another embodiment, the protein is associated with the exterior or interior surface of a cell membrane indirectly via association with another membrane spanning protein (i.e., the surface expressed protein is not spanning the cell membrane itself). In general, surface expressed proteins that are integrated into a cell membrane or expressed endogenously within a cell are more likely to fold in the correct conformation than recombinantly produced free forms of the same protein. 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, PD-L1 fragments include 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 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, or at least 250 contiguous amino acid residues of the amino acid sequence of a hPD-L1 polypeptide or an antibody that specifically binds to a hPD-L1 polypeptide. In a specific embodiment, a fragment of a hPD-L1 polypeptide or an antibody that specifically binds to a hPD-L1 antigen retains at least 1, at least 2, or at least 3 functions of the polypeptide or antibody.
-
The term “free” refers to a polypeptide, for example, PD-L1 or fragments and variants thereof, that is combined with a buffer, wherein the polypeptide is not associated with a cell surface or cell membrane. As such, the term “free” can refer to a polypeptide that is capable of surface expression (i.e., includes one or more transmembrane domains or membrane association domains), but that is not, in its present state, expressed on the surface of a cell or bound to a protein that is expressed on the surface of a cell. A free polypeptide can also refer to a free recombinant or native or unbound polypeptide.

Contact amino acid residues involved in the interaction of antibody and antigen may be determined by various known methods to those skilled in the art. In one embodiment, sequential replacement of the amino acids of the antigen sequence (using standard molecular biology techniques to mutate the DNA of the coding sequence of the antigen), in this case hPD-L1 with Alanine (a.k.a Alanine scan), or another unrelated amino acid, may provide residues whose mutation would reduce or ablate the ability of the antibody to recognise the antigen in question. Binding may be assessed using standard techniques, such as, but not limited to, SPR, HTRF, ELISA (which are described elsewhere herein). Other substitutions could be made to enhance the disruption of binding such as changing the charge on the side chain of antigen sequence amino acids (e.g. Lysine change to glutamic acid), switching polar and non-polar residues (e.g. Serine change to leucine). The alanine scan or other amino substitution method may be carried out either with recombinant soluble antigen, or where the target is a cell membrane target, directly on cells using transient or stable expression of the mutated versions. In one embodiment, protein crystallography may be used to determine contact residues between antibody and antigen (i.e. to determine the epitope to which the antibody binds), crystallography allows the direct visualisation of contact residues involved in the antibody-antigen interaction. As well as standard X-ray crystallography, cryo-electro microscopy has been used to determine contact residues between antibodies and HIV capsid protein (see Lee, Jeong Hyun, et al. “Antibodies to a conformational epitope on gp41 neutralize HIV-1 by destabilizing the Env spike.”, Nature communications, 6, (2015)). In one embodiment, if the antibody recognises a linear epitope, short peptides based on the antigen sequence can be produced and binding of the antibody to these peptides can be assessed using standard techniques, such as, but not limited to, SPR, HTRF, ELISA (which are described elsewhere herein). Further investigation of the epitope could be provided by performing an Alanine scan on any peptides that show binding. Alternative to linear peptides, conformational scans could be carried out using Pepscan technology (http://www.pepscan.com/) using their chemical linkage of peptides onto scaffolds, which has been used to determine discontinuous epitopes on CD20 targeting antibodies (Niederfellner, Gerhard, et al. “Epitope characterization and crystal structure of GA101 provide insights into the molecular basis for type I/II distinction of CD20 antibodies.”, Blood, 118.2, (2011), 358-367.). In one embodiment, limited proteolytic digestion and mass spectrophotometry can be used to identify binding epitopes. The antibody-antigen complex is digested by a protease, such as, but not limited to, trypsin. The digested complex peptides are compared to antibody-alone and antigen-alone digestion mass spectrophotometry to determine if a particular epitope is protected by the complexation. Further work involving amino acid substitution, competition binding, may then be employed to narrow down to individual amino acid residues involved in the interaction (see, for example, Suckau, Detlev, et al. “Molecular epitope identification by limited proteolysis of an immobilized antigen-antibody complex and mass spectrometric peptide mapping.”, Proceedings of the National Academy of Sciences, 87.24, (1990), 9848-9852). Thus, in one embodiment, the contact residues of the epitope are identified with an unrelated amino acid scan (e.g. alanine scan). In another embodiment, an unrelated amino acid scan (e.g. alanine scan) is carried out using a technique selected from SPR, HTRF, ELISA, X-ray crystallography, cryo-electro microscopy and a combination of limited proteolytic digestion and mass spectrometry. In one embodiment, the unrelated amino acid scan (e.g. alanine scan) is carried out using HTRF. In one embodiment, the unrelated amino acid scan (e.g. alanine scan) is carried out using ELISA. When the alanine scan is carried out with either ELISA or HTRF, an amino acid residue is identified as contributing to the epitope if the reduction in signal is at least 25%. In one embodiment, the reduction in signal is at least 30%. In one embodiment, the reduction in signal is at least 35%. In one embodiment, the reduction in signal is at least 40%. In one embodiment, the reduction in signal is at least 45%. In one embodiment, the reduction in signal is at least 50%. In one embodiment, the reduction in signal is at least 55%.

In one embodiment, the reduction in affinity is at least 15 fold. In one embodiment, the reduction in affinity is at least 20 fold. In one embodiment, the reduction in affinity is at least 30 fold.

As used herein, “inhibits”, “inhibition”, “inhibiting” and the like, as used herein refers to the ability of an antagonist (e.g. an antibody or fragment thereof) to bind to an epitope which either partially or completely prevents the binding of the receptor (e.g. CD80 or PD-1) to the ligand (e.g. PD-L1). If the epitope to which the antagonist binds completely blocks the binding site of the ligand, then ligand binding is completely prevented (which may be a physical blocking—in the case of overlapping epitopes—or steric blocking—where the antagonist is large such that it prevents the ligand binding to its distinct epitope), and the ligand is not removed from circulation. The concentration of circulating ligand may therefore appear to be increased. If the epitope to which the antagonist binds partially blocks the binding site of the ligand, the ligand may be able to bind, but only weakly (in the case of partial inhibition), or in a different orientation to the natural binding interaction. In this case, some of the ligand may be removed from circulation, but not as much as when the ligand binding site is completely free and available for binding. Inhibition thus refers to the physical interaction of ligand and receptor. Inhibition can be measured by HTRF, which is described in more detail elsewhere herein and in Mathis (1995) Clinical Chemistry 41(9), 1391-1397. Inhibition can also be measured by flow cytometry, where receptor is expressed on cells, or by ELISA, where receptor is adsorbed onto plates.

-
The potency of Fc-mediated effects may be enhanced by engineering the Fc domain by various established techniques. Such methods increase the affinity for certain Fc-receptors, thus creating potential diverse profiles of activation enhancement. This can be achieved by modification of one or several amino acid residues (e.g. as described in Lazar et al., 2006, Proc. Natl. Acad. Sci. U.S.A., March 14; 103(11):4005-10; the modifications disclosed therein are incorporated herein by reference). Human IgG1 constant regions containing specific mutations or altered glycosylation on residue Asn297 (e.g. N297Q, EU index numbering) have been shown to enhance binding to Fc receptors. In one embodiment, such mutations are one or more of the residues selected from 239, 332 and 330 for human IgG1 constant regions (or the equivalent positions in other IgG isotypes). In one embodiment, the antibody or fragment comprises a human IgG1 constant region having one or more mutations independently selected from N297Q, S239D, 1332E and A330L (EU index numbering).
-
In another embodiment, the increase in affinity for Fc-receptors is achieved by altering the natural glycosylation profile of the Fc domain by, for example, generating under fucosylated or de-fucosylated variants (as described in Natsume et al., 2009, Drug Des. Devel. Ther., 3:7-16 or by Zhou Q., Biotechnol. Bioeng., 2008, Feb. 15, 99(3):652-65), the modifications described therein are incorporated herein by reference). Non-fucosylated antibodies harbour a tri-mannosyl core structure of complex-type N-glycans of Fc without fucose residue. These glycoengineered antibodies that lack core fucose residue from the Fc N-glycans may exhibit stronger ADCC than fucosylated equivalents due to enhancement of FcγRIIIa binding capacity. For example, to increase ADCC, residues in the hinge region can be altered to increase binding to Fc-gamma RIII (see, for example, Shields et al., 2001, J. Biol. Chem., March 2; 276(9):6591-604; the modifications described therein are incorporated herein by reference). Thus, in one embodiment, the antibody or fragment comprises a human IgG heavy chain constant region that is a variant of a wild-type human IgG heavy chain constant region, wherein the variant human IgG heavy chain constant region binds to human Fcγ receptors selected from the group consisting of FcγRIIB and FcγRIIA with higher affinity than the wild type human IgG heavy chain constant region binds to the human Fcγ receptors. In one embodiment, the antibody or fragment comprises a human IgG heavy chain constant region that is a variant of a wild type human IgG heavy chain constant region, wherein the variant human IgG heavy chain constant region binds to human FcγRIIB with higher affinity than the wild type human IgG heavy chain constant region binds to human FcγRIIB. In one embodiment, the variant human IgG heavy chain constant region is a variant human IgG1, a variant human IgG2, or a variant human IgG4 heavy chain constant region. In one embodiment, the variant human IgG heavy chain constant region comprises one or more amino acid mutations selected from G236D, P238D, S239D, S267E, L328F, and L328E (EU index numbering system). In another embodiment, the variant human IgG heavy chain constant region comprises a set of amino acid mutations selected from the group consisting of: S267E and L328F; P238D and L328E; P238D and one or more substitutions selected from the group consisting of E233D, G237D, H268D, P271G, and A330R; P238D, E233D, G237D, H268D, P271G, and A330R; G236D and S267E; S239D and S267E; V262E, S267E, and L328F; and V264E, S267E, and L328F (EU index numbering system).

In another embodiment, the antibodies and fragments disclosed herein may comprise a triple mutation (M252Y/S254T/T256E) which enhances binding to FcRn. See Dall et al., Immunol 2002; 169:5171-5180 for a discussion of mutations affection FcRn binding in table 2, the mutations described therein are incorporated herein by reference.
-
Equally, the enhancement of CDC may be achieved by amino acid changes that increase affinity for C1q, the first component of the classic complement activation cascade (see Idusogie et al., J. Immunol., 2001, 166:2571-2575; the modifications described are incorporated herein by reference). Another approach is to create a chimeric Fc domain created from human IgG1 and human IgG3 segments that exploit the higher affinity if IgG3 for C1q (Natsume et al., 2008, Cancer Res., 68: 3863-3872; the modifications are incorporated herein by reference). In another embodiment, the antibody or antibody fragments disclosed herein may comprise mutated amino acids at residues 329, 331 and/or 322 to alter the C1q binding and/or reduced or abolished CDC activity. In another embodiment, the antibodies or antibody fragments disclosed herein may contain Fc regions with modifications at residues 231 and 239, whereby the amino acids are replaced to alter the ability of the antibody to fix complement. In one embodiment, the antibody or fragment has a constant region comprising one or more mutations selected from E345K, E430G, R344D and D356R, in particular a double mutation comprising R344D and D356R (EU index numbering system).
-
An antibody may have a heavy chain constant region that binds one or more types of Fc receptor but does not induce cellular effector functions, i.e. which does not mediate ADCC, CDC or ADCP activity. Such a constant region may be unable to bind the particular Fc receptor(s) responsible for triggering ADCC, CDC or ADCP activity. An antibody may have a heavy chain constant region that does not bind Fcγ receptors. Thus, in one embodiment, the constant region may comprise a Leu235Glu mutation (EU index numbering system).
-
In another embodiment, the antibodies and fragments disclosed herein are modified to increase or decrease serum half-life. In one embodiment, one or more of the following mutations: T252L, T254S or T256F are introduced to increase biological half-life of the antibody. Biological half-life can also be increased by altering the heavy chain constant region CH1 domain or CL region to contain a salvage receptor binding epitope taken from two loops of a CH2 domain of an Fc region of an IgG, as described in U.S. Pat. Nos. 5,869,046 and 6,121,022, the modifications described therein are incorporated herein by reference. In another embodiment, the Fc hinge region of an antibody or antigen-binding fragment of the invention is mutated to decrease the biological half-life of the antibody or fragment. One or more amino acid mutations are introduced into the CH2—CH3 domain interface region of the Fc-hinge fragment such that the antibody or fragment has impaired Staphylococcyl protein A (SpA) binding relative to native Fc-hinge domain SpA binding. Other methods of increasing serum half-life are known to those skilled in the art. Thus, in one embodiment, the antibody or fragment is PEGylated. In another embodiment, the antibody or fragment is fused to an albumin-binding domain, e.g. an albumin binding single domain antibody (dAb). In another embodiment, the antibody or fragment is PASylated (i.e. genetic fusion of polypeptide sequences composed of PAS (XL-Protein GmbH) which forms uncharged random coil structures with large hydrodynamic volume). In another embodiment, the antibody or fragment is XTENylated®/rPEGylated (i.e. genetic fusion of non-exact repeat peptide sequence (Amunix, Versartis) to the therapeutic peptide). In another embodiment, the antibody or fragment is ELPylated (i.e. genetic fusion to ELP repeat sequence (PhaseBio)). These various half-life extending fusions are described in more detail in Strohl, BioDrugs (2015) 29:215-239, which fusions, e.g. in Tables 2 and 6, are incorporated herein by reference.
-
The antibody may have a modified constant region which increases stability. Thus, in one embodiment, the heavy chain constant region comprises a Ser228Pro mutation. In another embodiment, the antibodies and fragments disclosed herein comprise a heavy chain hinge region that has been modified to alter the number of cysteine residues. This modification can be used to facilitate assembly of the light and heavy chains or to increase or decrease the stability of the antibody.

ICOS
-
“ICOS” or “the ICOS receptor” referred to herein may be human ICOS, unless the context dictates otherwise. Sequences of human, cynomolgus and mouse ICOS are shown in the appended sequence listing, and are available from NCBI as human NCBI ID: NP_036224.1, mouse NCBI ID: NP_059508.2 and cynomolgus GenBank ID: EHH55098.1.
-
The ICOS ligand (ICOSL, also known as B7-H2) is a cell surface expressed molecule that binds to the ICOS receptor [23]. This intercellular ligand-receptor interaction promotes multimerisation of ICOS on the T cell surface, activating the receptor and stimulating downstream signalling in the T cell. In effector T cells, this receptor activation stimulates the effector T cell response.
Antibodies to ICOS
-
Anti-ICOS antibodies may act as agonists of ICOS, mimicking and even surpassing the stimulatory effect of the native ICOS ligand on the receptor. Such agonism may result from ability of the antibody to promote multimerisation of ICOS on the T cell. One mechanism for this is where the antibodies form intercellular bridges between ICOS on the T cell surface and receptors on an adjacent cell (e.g., B cell, antigen-presenting cell, or other immune cell), such as Fc receptors and/or receptors to which the multi-specific antibody binds. Another mechanism is where antibodies having multiple (e.g., two) antigen-binding sites (e.g., two VH-VL domain pairs) bridge multiple ICOS receptor molecules and so promote multimerisation. A combination of these mechanisms may occur.
-
A bispecific antibody combining both ICOS agonism with PD-L1 antagonism may act via its PD-L1 binding arm (e.g., Fcab) to inhibit the negative co-regulatory signals generated by PD-L1 expressed on APCs, myeloid-derived suppressor cells (MDSC) or tumour cells, and may instead deliver a positive agonistic signal via its ICOS binding arm (e.g., Fab). See FIG. 1 .
-
An antibody to ICOS that acts to increase effector T cell activity represents a therapeutic approach in immunooncology and in other medical contexts where a CD8+ T cell response is beneficial. In many diseases and conditions involving an immune component, a balance exists between effector T cells (TEff) which exert the CD8+ T cell immune response, and regulatory T cells (TReg) which suppress that immune response by downregulating TEffs. The present invention relates to antibodies that modulate this TEff/TReg balance in favour of effector T cell activity. Antibodies that trigger the depletion of ICOS highly positive regulatory T cells would relieve the suppression of TEffs, and thus have a net effect of promoting the effector T cell response. An additional or complementary mechanism for an anti-ICOS antibody is via agonistic activity at the ICOS receptor level, to stimulate the effector T cell response.
-
The relative expression of ICOS on effector T cells (TEff) compared with regulatory T cells (TReg), and the relative activities of these cell populations, will influence the overall effect of an anti-ICOS antibody in vivo. An envisaged mode of action combines agonism of effector T cells with depletion of ICOS positive regulatory T cells. Differential and even opposing effects on these two different T cell populations may be achievable due to their different levels of ICOS expression. Dual-engineering of the variable and constant regions respectively of an anti-ICOS antibody can provide a molecule that exerts a net positive effect on effector T cell response by affecting the CD8/TReg ratio. An antigen-binding domain of an agonist antibody, which activates the ICOS receptor, may be combined with an antibody constant (Fc) region that promotes downregulation and/or clearance of highly expressing cells to which the antibody is bound. An effector positive constant region may be used to recruit cellular effector functions against the target cells (TRegs), e.g., to promote antibody-dependent cell-mediated cytotoxicity (ADCC) or antibody dependent cell phagocytosis (ADCP). A bispecific antibody binding to ICOS and PD-L1 may trigger ADCC of PD-L1+ immunosuppressive cells (e.g., MDSC, tumour cells) and ICOS+ immunosuppressive cells (Tregs). The antibody may thus act both to promote effector T cell activation and to downregulate immunosuppressive T Regulatory cells. Since ICOS is more highly expressed on TRegs than on TEffs, a therapeutic balance may be achieved whereby Teff function is promoted while TRegs are depleted, resulting in a net increase in the T cell immune response (e.g, anti-tumour response or other therapeutically beneficial T cell response).
-
The ICOS binding site of multi-specific antibodies described herein may bind human ICOS. The antibodies target the ICOS extracellular domain and thereby bind to T cells expressing ICOS. Examples are provided of antibodies that have been designed to have an agonistic effect on ICOS, thus enhancing the function of effector T cells, as indicated by an ability to increase IFNγ expression and secretion. As noted, anti-ICOS antibodies may also be engineered to deplete cells to which they bind, which should have the effect of preferentially downregulating regulatory T cells, lifting the suppressive effect of these cells on the effector T cell response and thus promoting the effector T cell response overall. Regardless of their mechanism of action, it is demonstrated empirically herein that anti-ICOS antibodies stimulate T cell response and have anti-tumour effects in vivo, as shown in the Examples. Through selection of appropriate antibody formats such as those including constant regions with a desired level of Fc effector function, or absence of such effector function where appropriate, the anti-ICOS antibodies may be tailored for use in a variety of medical contexts including treatment of diseases and conditions in which an effector T cell response is beneficial and/or where suppression of regulatory T cells is desired.

“Specifically binds” has the meaning provided hereinabove. Binding constants, e.g. KD may be determined as described elsewhere herein, and particular KDs of interest are described in arrangement 2 below, and in concept 1 hereinabove (although specified for PD-L1 binding, the values of KD may be equally applied to anti-ICOS binding).
-
Arrangement 2. A multispecific antibody according to arrangement 1, wherein the ICOS is human ICOS.
-
Sequences of human ICOS are provided in Seq ID Nos:506, 507 and 508. In one embodiment, the multispecific antibody is specific for wild type human ICOS. In another embodiment, the multispecific antibody is cross-reactive to an isoform or natural variant of hICOS, for example the isoform of Seq ID No:509. Other isoforms and natural variants are well known to those skilled in the art. In another embodiment, the multispecific antibody is specific for the isoform or natural variant (e.g. the ICOS isoform having the amino acid sequence of Seq ID No:509) over wild type hICOS.
-
One way to quantify the extent of species cross-reactivity of an antibody, e.g. a multispecific, bispecific or dual-binding antibody is as the fold-difference in its affinity for antigen compared with a different antigen (e.g. fold difference in affinity for human ICOS vs mouse ICOS or fold difference in affinity for wild-type hICOS vs an isoform of hICOS). Affinity may be quantified as KD, referring to the equilibrium dissociation constant of the antibody-antigen reaction as determined by SPR (optionally with the antibody in Fab format as described elsewhere herein). A species or isoform cross-reactive anti-ICOS antibody may have a fold-difference in affinity for binding human and mouse ICOS that is 30-fold or less, 25-fold or less, 20-fold or less, 15-fold or less, 10-fold or less or 5-fold or less. To put it another way, the KD of binding the extracellular domain of hICOS may be within 30-fold, 25-fold, 20-fold, 15-fold, 10-fold or 5-fold of the KD of binding the extracellular domain of mouse ICOS. Antibodies can also be considered cross-reactive if the KD for binding antigen of both species meets a threshold value, e.g., if the KD of binding hICOS and the KD of binding mouse ICOS are both 10 mM or less, preferably 5 mM or less, more preferably 1 mM or less. The KD may be 10 nM or less, 5 nM or less, 2 nM or less, or 1 nM or less. The KD may be 0.9 nM or less, 0.8 nM or less, 0.7 nM or less, 0.6 nM or less, 0.5 nM or less, 0.4 nM or less, 0.3 nM or less, 0.2 nM or less, or 0.1 nM or less.
-
An alternative measure of cross-reactivity for binding hICOS and mouse ICOS, or VVT hICOS and an isoform of hICOS is the ability of an antibody to neutralise ICOS ligand binding to ICOS receptor, such as in an HTRF assay (as described elsewhere herein). Examples of species cross-reactive antibodies are provided herein, including STIM001, STIM002, STIM002-B, STIM003, STIM005 and STIM006, each of which was confirmed as neutralising binding of human B7-H2 (ICOS ligand) to hICOS and neutralising binding of mouse B7-H2 to mouse ICOS in an HTRF assay. Any of these antibodies or their variants may be selected when an antibody cross-reactive for human and mouse ICOS is desired. A species cross-reactive anti-ICOS antibody may have an IC50 for inhibiting binding of hICOS to human ICOS receptor that is within 25-fold, 20-fold, 15-fold, 10-fold or 5-fold of the IC50 for inhibiting mouse ICOS to mouse ICOS receptor as determined in an HTRF assay. Antibodies can also be considered cross-reactive if the IC50 for inhibiting binding of hICOS to human ICOS receptor and the IC50 for inhibiting binding of mouse ICOS to mouse ICOS receptor are both 1 mM or less, preferably 0.5 mM or less, e.g., 30 nM or less, 20 nM or less, 10 nM or less. The IC50s may be 5 nM or less, 4 nM or less, 3 nM or less or 2 nM or less. In some cases, the IC50s will be at least 0.1 nM, at least 0.5 nM or at least 1 nM.

Affinities may also be as disclosed in concept 27 hereinabove.

In one embodiment, the anti-ICOS VH and/or VL is as described in GB patent application 1620414.1 (filed 1 Dec. 2016), the contents of which are incorporated herein by reference.
-
Arrangement 7. A multispecific antibody according to any preceding arrangement, which has agonistic activity against ICOS.
-
Agonism can be tested for in an in vitro T-cell activation assays, using antibody in soluble form (e.g. in immunoglobulin format or other antibody format comprising two spatially separated antigen-binding sites, e.g., two VH-VL pairs), either including or excluding a cross-linking agent, or using antibody (e.g. multispecific antibody) bound to a solid surface to provide a tethered array of antigen-binding sites. Agonism assays may use a hICOS positive T-lymphocyte cell line such as MJ cells (ATCC CRL-8294) as the target T-cell for activation in such assays. One or more measures of T-cell activation can be determined for a test antibody and compared with a reference molecule or a negative control to determine whether there is a statistically significant (p<0.05) difference in T-cell activation effected by the test antibody (e.g. multispecific antibody) compared with the reference molecule or the control. One suitable measure of T-cell activation is production of cytokines, e.g., IFNγ, TNFα or IL-2. A skilled person will include suitable controls as appropriate, standardising assay conditions between test antibody and control. A suitable negative control is an antibody in the same format (e.g., isotype control) that does not bind ICOS, e.g., an antibody (e.g. multispecific antibody) specific for an antigen that is not present in the assay system. A significant difference is observed for test antibody relative to a cognate isotype control within the dynamic range of the assay is indicative that the antibody acts as an agonist of the ICOS receptor in that assay.
-
An agonist antibody may be defined as one which, when tested in a T-cell activation assay:
-
has a significantly lower EC50 for induction of IFNγ production compared with control antibody;
-
induces significantly higher maximal IFNγ production compared with control antibody;
-
has a significantly lower EC50 for induction of IFNγ production compared with ICOSL-Fc;
-
induces significantly higher maximal IFNγ production compared with ICOSL-Fc;
-
has a significantly lower EC50 for induction of IFNγ production compared with reference antibody C398.4A; and/or
-
induces significantly higher maximal IFNγ production compared with reference antibody C398.4A.
-
A significantly lower or significantly higher value may for example be up to 0.5-fold different, up to 0.75-fold different, up to 2-fold different, up to 3-fold different, up to 4-fold different or up to 5-fold different, compared with the reference or control value.
-
Thus, in one example, an antibody (e.g. a multispecific antibody) provided herein has a significantly lower, e.g., at least 2-fold lower, EC50 for induction of IFNγ in an MJ cell activation assay using the antibody in bead-bound format, compared with control.
-
The bead-bound assay uses the antibody (e.g. multispecific antibody) (and, for control or reference experiments, the control antibody, reference antibody or ICOSL-Fc) bound to the surface of beads. Magnetic beads may be used, and various kinds are commercially available, e.g., Tosyl-activated DYNABEADS M-450 (DYNAL Inc, 5 Delaware Drive, Lake Success, N.Y. 11042 Prod No. 140.03, 140.04). Beads may be coated (coating methods are well-known to those skilled in the art), or generally by dissolving the coating material in carbonate buffer (pH 9.6, 0.2 M) or other method known in the art. Use of beads conveniently allows the quantity of protein bound to the bead surface to be determined with a good degree of accuracy. Standard Fc-protein quantification methods can be used for coupled protein quantification on beads. Any suitable method can be used, with reference to a relevant standard within the dynamic range of the assay. DELFIA, ELISA or other methods could be used.
-
Agonism activity of an antibody can also be measured in primary human T-lymphocytes ex vivo. The ability of an antibody (e.g. multispecific antibody) to induce expression of IFNγ in such T-cells is indicative of ICOS agonism. Preferably, an antibody will show significant (p<0.05) induction of IFNγ at 5 μg/mL compared with control antibody in a T-cell activation assay. An anti-ICOS antibody may stimulate T-cell activation to a greater degree than ICOS-L or C398.4 in such an assay. Thus, the antibody may show significantly (p<0.05) greater induction of IFNγ at 5 μg/mL compared with the control or reference antibody in a T-cell activation assay. TNFα or IL-2 induction may be measured as an alternative assay readout.
-
Agonism of an anti-ICOS antibody may contribute to its ability to change the balance between populations of TReg and TEff cells in vivo, e.g., in a site of pathology such as a tumour microenvironment, in favour of TEff cells. The ability of an antibody to enhance tumour cell killing by activated ICOS-positive effector T-cells may be determined, as discussed elsewhere herein.
-
Arrangement 8. A multispecific antibody according to any preceding arrangement, which binds (and optionally has specificity for) mouse ICOS and/or cynomolgus ICOS.

The multispecific antibodies described herein may be cross-reactive, and may for example bind the extracellular domain of mouse ICOS as well as human ICOS. The multispecific antibodies may bind other non-human ICOS, including ICOS of primates, such as cynomolgus monkey. An anti-ICOS multispecific antibody intended for therapeutic use in humans must bind human ICOS, whereas binding to ICOS of other species would not have direct therapeutic relevance in the human clinical context. Regardless of the underlying theory, however, cross-reactive antibodies are of high value and are excellent candidates as therapeutic molecules for pre-clinical and clinical studies. Cross-reactivity may be determined as set out for arrangement 2 hereinabove.

EXAMPLES
-
A number of bispecific antibodies were generated, using different antibody formats, and with different anti-ICOS and anti-PD-L1 binding sites. Bispecific antibodies were shown to bind and induce an agonistic signal at ICOS, to bind to PD-L1 inhibiting the interaction with PD-1, and to deplete cells expressing high levels of ICOS.
-
Anti-ICOS Fv regions of antibodies, and anti-PD-L1 Fv regions of antibodies, can be generated using the Kymouse—a transgenic mouse technology platform. Kymouse covers the entire human immunoglobulin (Ig) repertoire of V, D and J genes required to make fully human antibodies. On selection and recovery of recombined variable regions, the antibodies are re-formatted to yield antibodies with isotypes or Fc-domains of choice. STIM001 and STIM003 are anti-ICOS antibodies originating from the Kymouse. Their Fv regions were included in bispecific antibody formats as described in these Examples.
-
The example anti-PD-L1 binding domains that were used in the mAb2 bispecific antibodies described in these Examples were produced as Fcabs, utilising permissive residues in the CH3 domain of the constant chain of human IgG1 termed the AB, CD and EF loops to generate IgG-based Fcabs which bind PD-L1.
Example 1 Generation of ICOS/PD-L1 Bispecific Antibody
FIT-Ig
-
Bispecific antibodies for ICOS and PD-L1 were generated in FIT-Ig format, as illustrated in FIG. 2 .
-
The anti-PD-L1/ICOS tetravalent bispecific FIT-Ig molecule combines the variable regions of an anti-ICOS antibody with the variable regions of an anti-PD-L1 antibody. The bispecific molecule presents two Fabs in tandem, fused with an Fc. The molecules are symmetrical.
-
In this example, the anti-ICOS antibody domains were those of STIM003 and the anti-PD-L1 antibody domains were those of Antibody W. The FIT-Ig molecules were generated with anti-ICOS binding specificity as the “outer” Fab (antibody A in FIG. 2 ) or with anti-ICOS binding specificity as the “inner” Fab (antibody B in FIG. 2 ). Fc domains were either human IgG1 or mouse IgG2a. Thus a total of four different FIT-Ig molecules were produced using the STIM003 and AbW binding specificities:
-
ICOS/PD-L1 hIgG1
-
ICOS/PD-L1 mIgG2a
-
PD-L1/ICOS hIgG1
-
PD-L1/ICOS mIgG2a
-
For each FIT-Ig molecule, the three constructs shown in FIG. 2 (ii) were generated, and cloned into an expression vector (pTT5) via restriction enzymes and sequences were verified. A 30 mL HEK transient transfection was then performed, using the three constructs in 1:1:1 ratio. After 6 days, supernatant was analysed to assess the level of expression, quantifying using human IgG1 and mouse IgG2a as standards. Expression data are shown in Table E1-1 below.

Bispecific antibodies for ICOS and PD-L1 were generated in mAb2 format, as illustrated in FIG. 3 . The following molecules were generated and expressed:
-
|
STIM001_289. |
A mAb2 IgG1 in which the two Fab regions comprise |
|
the VH and VL domains of anti-ICOS antibody |
|

A mAb2 IgG1 in which the two Fab regions comprise |
|

|
STIM001 and the Fcab region binds mouse PD-L1. |
STIM003_289. |
A mAb2 IgG1 in which the two Fab regions comprise |
|
the VH and VL domains of anti-ICOS antibody |
|
STIM003 and the Fcab region binds human PD-L1. |
STIM003_457. |
A mAb2 IgG1 in which the two Fab regions comprise |
|
the VH and VL domains of anti-ICOS antibody |
|
STIM003 and the Fcab region binds mouse PD-L1. |
|
-
The following control antibodies were also generated for use in the experiments:
-
|
IgG1_289. |
A mAb2 IgG1 in which the two Fab regions do not bind |
|
ICOS or PD-L1, and the Fcab region binds human PD-L1. |
IgG1_457. |
A mAb2 IgG1 in which the two Fab regions do not bind |
|
ICOS or PD-L1, and the Fcab region binds mouse PD-L1. |
IgG1_438. |
A mAb2 IgG1 in which the two Fab regions do not bind |
|
ICOS or PD-L1, and the Fcab region binds mouse PD-L1. |
|
IgG1_438 and IgG1_457 have minor variation in the |
|
amino acid sequences of the antigen-binding loops in the |
|
Fcab and are functionally equivalent for the purposes of |
|
the assays described below. |
|
-
The mAb2 antibodies were generated as IgG1, containing IgG1 CH1, CH2 and CH3 constant regions, with the Fcab binding loops in the IgG1 CH3 constant region. Unless otherwise stated, IgG1 was wild type human IgG1. The “LAGA” variant IgG1 sequence was used where specified. The “LAGA” variant includes mutations L235A and G237A which disable Fc-mediated effects ADCC and CDC as described in WO99/58679 and in Shields et al. J. Biol. Chem., March 2; 276(9):6591-604 2001.
Example 2 Kinetic Surface Plasmon Resonance (SPR) Assay for Characterisation of Bispecific Antibody Binding to ICOS and PD-L1
-
Analysis of mAb2 Binding to Human PD-L1 and Mouse PD-L1
-
This kinetic SPR assay confirmed that addition of human variable regions to anti-PD-L1 Fcab molecules to create mAb2 constructs did not affect the ability of the Fcab to recognise PD-L1. Six different mAb2_289 constructs exhibited similar binding to human PD-L1, and six different mAb2_457 constructs exhibited similar binding to mouse PD-L1.
Method:
-
An anti-human IgG capture surface was created on a Series S C1 chip (GE Healthcare, cat No BR100535). A cocktail of three anti-human IgG antibodies were covalently coupled to the biosensor chip surface (Jackson Labs: cat No 109-005-008; cat No 309-006-008 and cat No 109-006-008), using 10 mM Na Acetate pH 4.5 buffer as the diluent for the antibody.
-
For the kinetic assay, mAb2 constructs were diluted to 5 μg/mL in running buffer (1×HBS-EP+ Buffer Technova, cat. No. H8022) and captured on the anti-human capture surface. The human recombinant extra cellular domain PD-L1 protein was used as analyte at 81 nM, 27 nM, 9 nM, 3 nM, 1 nM and 0 nM, and injected over the mAb2_289 constructs. The mouse recombinant extra cellular domain PD-L1 protein was injected as analyte at 243 nM, 81 nM, 27 nM, 9 nM, 3 nM, 1 nM and 0 nM over the mAb2_457 constructs. Finally, the surface was regenerated between each mAb2 construct using 100 mM PO4. The assay was carried out at 25° C.
-
The buffer injection (i.e. 0 nM) was used to double reference the sensorgrams. The analysis was carried out using the 1:1 binding model inherent to the Biacore 8K's analysis software.

-
Data for binding to human PD-L1 are shown in Table E2-1 below.

-
With respect to the KD values, the binding of the mAb2_457 constructs to mouse PD-L1 is comparable. However, given that the apparent affinity of the interaction is in the 80-110 nM range and the top concentration of mouse recombinant extra cellular domain PD-L1 was only 243 nM, it is unlikely that a true saturated Rmax was achieved in this assay, hence the actual affinity may be lower than indicated by these data. Nevertheless it can be concluded that the constructs are comparable in their binding and the anti-PD-L1 Fcab retains its binding for mouse PD-L1 when incorporated into a mAb2 format.

Avidity Surface Plasmon Resonance Analysis of mAb2 Binding to Human ICOS
-
This avidity SPR assay confirmed that the bispecific mAb2 constructs were able to bind ICOS. Values obtained for binding were similar across all samples tested and within experimental variance for this type of assay, where capture level, concentration and biophysical form can have an impact on values.
Method:
-
Biotinylated human ICOS protein diluted at 7.5 μg/mL in running buffer (1×HBS-EP+ Buffer Technova, cat. No. H8022) was captured on a NLC sensor chip (Bio-Rad, cat No 1765021). The surface was then blocked using biocytin (Sigma Aldrich, cat No B1758) at 1 mg/mL.
-
The ICOS/PD-L1 bispecific mAb2 and the corresponding human anti-ICOS IgG1 constructs were injected as analyte at 500, 167, 56, 18.5 and 0 nM for the STIM001_mAb2 and STIM001, and at 40, 10, 2.5, 0.625 and 0 nM for the STIM003_mAb2 and STIM003. The assay was carried out at 25° C.
-
The buffer injection (i.e. 0 nM) was used to double reference the sensorgrams. The analysis was carried out using the equilibrium model inherent to the ProteOn's analysis software for each mAb2 construct.

Example 3 ELISA Characterisation of Bispecific Antibody Binding to ICOS and PD-L1
-
Antibodies in mAb2 format were assessed for binding to recombinant human ICOS, mouse ICOS, human PD-L1 and mouse PD-L1 proteins. Binding of the ICOS/PD-L1 bispecific mAb2 antibodies to recombinant ICOS protein and recombinant PD-L1 protein was confirmed in this assay.
Delfia ELISA Method:
-
Recombinant ICOS proteins, human ICOS-mFc or mouse ICOS-mFc (Chimerigen) were diluted in 1×PBS and added to Black Hi-bind plates (Griener) at 1 μg/ml, 50 μl/well. Recombinant PD-L1 proteins, human PD-L1-Flag-His or mouse-His were diluted in 1×PBS and added to Black Hi-bind plates (Griener) at 4 μg/ml, 50 μl/well. The plates were left overnight at 4° C. The next day plates were washed 3× with 300 μl/well of 1×PBS+0.1% Tween and blocked with 200 ul/well of 1×PBS+1% BSA blocking buffer for 1 hr at RT on a plate shaker. Plates were washed 3× with 300 μl/well of 1×PBS+0.1% Tween.
-
In general, antibodies in monoclonal and mAb2 format were diluted in 1×PBS+0.1% BSA buffer and diluted 1 in 3 from starting working concentration of either 0.399 μM, 0.199 μM over a 11 point titration. However, human-PD-L1 mAb2 antibodies were diluted in 1×PBS+0.1% BSA buffer and diluted 1 in 2 from a starting working concentration of 0.066 μM over an 11 point titration. Titrated antibodies were added to the plates, 50 μl/well and left to incubate for 1 hr at R.T on a plate shaker. Plates were washed 3× with 300 μl/well of 1×PBS+0.1% Tween.
-
DELFIA® Eu-labelled Anti-human IgG (Perkin-Elmer) was diluted 1:500 in DELFIA Assay buffer (Perkin-Elmer) and added to the assay plate (50 μl/well), left to incubate for 1 hr at RT on a plate shaker. Plates were then washed 3× with 300 μl/well 1×DELFIA wash buffer before the addition of 50 μl/well of DELFIA Enhancement Solution (Perkin-Elmer), incubated for a minimum of 5 minutes in the dark. After incubation, assay was read on Envision plate reader (Perkin Elmer), Time-resolved fluorescence (TRF) was measured at 615 nm.
-
Titration curves and EC50 values [M] were plotted using Graphpad (Prism). EC50 values were calculated by first transforming the data using equation X=Log(X). The transformed data was then fitted using nonlinear regression, using fitting algorithm, log (agonist) vs. response—variable slope (four parameters).

Example 4 FACS Characterisation of Bispecific Antibody Binding to Cells Expressing ICOS or PD-L1
CHO Human ICOS and CHO Mouse ICOS Binding Assay (Flow Cytometry)
-
Ability of the ICOS/PD-L1 mAb2 to bind human ICOS and mouse ICOS on the surface of CHO cells was confirmed in this assay. STIM001_289 mAb2 and STIM003_289 mAb2 were assessed for binding to transfected human ICOS and mouse ICOS CHO cells. Antibody binding to cells was detected with anti-human IgG labelled AlexaFluor 647.
Method:
-
CHO-S cells transfected with either human ICOS or mouse ICOS were resuspended in FACS buffer (PBS+1% w/v BSA+0.1% w/v sodium azide) and transferred to a 96-well V-bottom plate (Greiner) at a density of 1×105 cells per well. mAb and mAb2 were titrated in FACS buffer, 1 in 3 dilution across 11 points from a starting working concentration of 400 nM. Plates were centrifuged at 300×g for 3 minutes, supernatant discarded and 50 μL mAb or mAb2 solution were added to cells and incubated at 4° C. for 1 hour. Cells were washed with 150 μL of PBS and centrifuged at 300×g for 3 minutes, supernatant was discarded and cell pellet resuspended in 150 μL PBS added. This wash step was repeated twice. Bound mAb or mAb2 was detected by addition of 50 μL of anti-human 647 (Jackson ImmunoResearch) diluted to 3 ug/ml in FACS buffer. Cells were incubated for 1 hour at 4° C. in the dark. Cells were washed with 150 μL of PBS and centrifuged at 300 g for 3 minutes, supernatant was discarded and cell pellet resuspended in 150 μL PBS added. This wash step was repeated twice. Cells were fixed with 25 μL 4% v/v paraformaldehyde, incubated for 20 minutes at 4° C., cells were pelleted by centrifugation at 300×g and the supernatant discarded. Cells were washed with 150 μL of PBS and centrifuged at 300 g for 3 minutes, supernatant was discarded and cell pellet resuspended in 150 μL PBS added. This wash step was repeated. Pelleted cells were resuspended in 110 μL 1×PBS. AlexaFluor 647 signal intensity (geometric mean) was measured by flow cytometry using a Beckman Coulter CytoFLEX instrument.

CHO Human PD-L1 Binding Assay Assay (Flow Cytometry)
-
Ability of the ICOS/PD-L1 mAb2 to bind human PD-L1 expressed on the surface of CHO cells was confirmed in this assay. Binding of the bispecific antibody to PD-L1 could be detected using labelled ICOS recombinant protein, confirming the ability of the bispecific antibodies to bind both PD-L1 and ICOS.
-
STIM001_289 and STIM003_289 and one isotype control (IgG1_289) were assessed for human PD-L1 binding using FACS. These were characterised using anti-human IgG and human ICOS labelled AlexaFluor 647 detection.
Method:
-
CHO-S cells untransfected (referred to as VVT) or transfected with the cDNA coding for human PD-L1 were diluted in FACS buffer (PBS+1% w/v BSA+0.1% w/v sodium azide) and were distributed to a 96-well V-bottom plate (Greiner) at a density of 5×104 cells per well. Antibody and mAb2 titrations were prepared from 198 nM working concentration as a ⅓ dilution series in FACS buffer. Plates were centrifuged at 300×g for 3 minutes to supernatant aspirated. 50 μL antibody or mAb2 solution were added to cells and incubated at 4° C. for 1 hour. Cells were washed with 150 μL of PBS and centrifuged at 300 g for 3 minutes. Supernatant was aspirated and 150 μL PBS added. This wash step was repeated. Presence of bound antibody or mAb2 was detected by addition of 50 μL of Anti-Human PE (Jackson ImmunoResearch) diluted 1/500 in FACS buffer or human ICOS labelled AlexaFluor 647 diluted to 225 nM to each well. Cells were incubated for 1 hour at 4° C. in the dark. Cells were washed as previously described. To fix cells, 100 μL 4% v/v paraformaldehyde was added and cells incubated for 20 minutes at 4° C., cells were pelleted by centrifugation at 300×g and the plates resuspended in 100 μL FACS buffer. AlexaFluor 647 and PE (R-Phycoerythrin) signal intensity (geometric mean) was measured by flow cytometry using a Beckman Coulter CytoFLEX instrument.
Results:
-
Bispecific antibodies and isotype control produced similar EC50 values to each other in the anti-human IgG detection system (0.64 nM, 0.64 nM and 0.55 nM respectively) —FIG. 6 (A). Bispecific antibodies produced similar EC50 values to each other in the human ICOS labelled AlexaFluor 647 system (0.48 nM and 0.58 nM respectively)—FIG. 6 (B). As expected, the isotype control antibody did not bind ICOS.
-
Also as expected, monospecific antibodies STIM001, STIM003 and control IgG1 did not show binding to human PD-L1 with either anti-human IgG detection or human ICOS labelled AlexaFluor 647.
CHO Mouse PD-L1 Binding Assay (Flow Cytometry)
-
Ability of the ICOS/PD-L1 mAb2 to bind mouse PD-L1 on the surface of CHO cells was confirmed in this assay. Binding of the bispecific antibody to PD-L1 could be detected using ICOS, confirming the ability of the bispecific antibodies to bind both PD-L1 and ICOS.
-
STIM001_457 and STIM003_457 and one isotype control (IgG1_438) were assessed for human PD-L1 binding using FACS. These were characterised using anti-human IgG and human ICOS labelled AlexaFluor 647 detection.
Method:
-
CHO-S cells untransfected (referred to as VVT) or transfected with mPD-L1 were diluted in FACS buffer (PBS+1% w/v BSA+0.1% w/v sodium azide) and were distributed to a 96-well V-bottom plate (Greiner) at a density of 5×104 cells per well. Monospecific mAb and bispecific mAb2 titrations were prepared from 22 nM working concentration as a ⅓ dilution series in FACS buffer. Plates were centrifuged at 300×g for 3 minutes to supernatant aspirated. 50 μL antibody or mAb2 solution were added to cells and incubated at 4° C. for 1 hour. Cells were washed with 150 μL of PBS and centrifuged at 300 g for 3 minutes. Supernatant was aspirated and 150 μL PBS added. This wash step was repeated. Presence of bound mAb or mAb2 was detected by addition of 50 μL of Anti-Human IgG PE (Jackson ImmunoResearch) diluted 1/500 in FACS buffer or human ICOS labelled AlexaFluor 647 diluted to 25 nM to each well. Cells were incubated for 1 hour at 4° C. in the dark. Cells were washed as previously described. To fix cells, 100 μL 4% v/v paraformaldehyde was added and cells incubated for 20 minutes at 4° C., cells were pelleted by centrifugation at 300×g and the plates resuspended in 100 μL FACS buffer. AlexaFluor 647 and PE (R-Phycoerythrin) signal intensity (geometric mean) was measured by flow cytometry using a Beckman Coulter CytoFLEX instrument.
Results:
-
Bispecific antibodies and isotype control produced similar EC50 values to each other in the anti-human IgG detection system (0.89±0.64 nM, 0.47±0.23 nM and 0.59±0.20 nM respectively)—FIG. 7 (A)—and in the human ICOS labelled AlexaFluor 647 system (1.29±1.26 nM and 0.81±0.56 nM respectively)—FIG. 7 (B). The isotype control did show binding.
-
Monospecific antibodies STIM001, STIM003 and IgG1 did not show binding to human PD-L1 with either anti-human IgG detection or human ICOS labelled AlexaFluor 647.
Example 5a Biolayer Interferometry Determination of mAb2 Binding to Fcγ Receptors
Materials:
-
Sensors coated with a commercial anti-human FAb-CH1 ligand (Pall ForteBio, cat No 18-5125) were hydrated for 10 min in running buffer (1×HBS-EP+ Buffer: Technova, cat. No. H8022).
-
The mAb2_289 constructs STIM001_289 and STIM003_289 were diluted to 45 μg/mL in running buffer.
-
The recombinant human FcγRI (1257-FC-050, R&D Systems), mouse FcγRI (2074-FC-050, R&D Systems) and mouse FcγRIV (1974-CD-050, R&D Systems) were diluted to 1 μM in running buffer. The recombinant human FcγRIIIa (4325-FC-050, R&D Systems) and mouse FcγRIII (1960-FC-050, R&D Systems) were diluted to 2 μM in running buffer. Finally, the recombinant human FcγRIIa (1330-CD-050, R&D Systems), human FcγRIIb/c (1875-CD-050, R&D Systems) and mouse FcγRIIb (1460-CD-050, R&D Systems) were diluted to 3 μM in running buffer.
-
The human recombinant extracellular domain PD-L1 protein was diluted to 1 μM in running buffer.
Method:
-
The anti-human FAb-CH1 sensors were regenerated with 100 mM PO4 then equilibrated in running buffer. STIM001_289 and STIM003_289 were captured at 45 μg/mL on the sensors and then loaded with 1 μM of human PD-L1. Finally, the sensors were dipped into the Fcγ receptor solution. The sensors were then regenerated and equilibrated again, and the same protocol was repeated for each Fcγ receptor. The assay was carried out at 25° C.

Example 5b Engagement of Fc Receptor on ADCC Effector Cells by Fc Region of Bispecific Antibody to ICOS and PD-L1
-
This assay determines ability of the Fc region of mAb2 to engage FcγRIIIa on effector cells.
Method:
-
Immediately prior to the assay CHO (target) cells expressing human ICOS or mouse ICOS were centrifuged and resuspended in RPMI 1640 (Promega)+4% Low IgG serum (Promega) and plated at 50000 cells/well (25 μl/well) in 96-well white bottom TC-treated plates (Costar).
-
All antibodies were serially diluted 1 in 3 over 9 points, in RPMI 1640+4% Low IgG serum. For assays with human ICOS expressing target cells, the antibodies were diluted from starting working concentration of 10 nM and for mouse ICOS expressing target cells the mAb2 and mAb were diluted from a starting working concentration of 20 nM and 35 nM, respectively. Diluted antibodies (25 μl/well) were added to the target cells and left to incubate for 0.5 hrs at room temperature. Thawed Jurkat NFAT luciferase v-variant effector cells (Promega) were resuspended in RPMI 1640+4% low IgG serum and added to the target cell/antibody mixture at 10000 cells/well (25 μl/well). After overnight incubation at 37° C., 5% CO2, luciferase activity was measured by adding luminogenic BioGlo substrate at 75 μl/well (Promega) directly to the wells, plates incubated for 10 min in the dark and read on an Envision (Perkin Elmer) plate reader.
-
Relative light unit (RLU) values from the raw data (Envision reads) were first normalised to ‘fold of induction’ using the following equation.
-
-
Mean and standard deviation ‘fold of induction’ values for each antibody concentration were plotted and curves were fitted using the GraphPad Prism 4-parameter log-logistic curve. The average ‘fold of induction’ values for each experiment were then used to plot the inter-experimental values (+1-SD) from all three experiments.
Results:
-
Data are summarised in Table E5-1 and in FIGS. 8 A and B. STIM003_289 and STIM001_289 produced similar EC50 values in the human and mouse ICOS ADCC assay.

Example 5c ADCC Assay Using Peripheral Blood Mononuclear Cells (PBMC)
-
The potential to kill via ADCC (“antibody-dependent cell-mediated cytotoxicity”) of STIM001_289 and STIM003_289 was compared with that of STIM001 and STIM003 in the Delfia BATDA cytotoxicity assay (Perkin Elmer) using human primary NK cells as effector and ICOS-transfected CCRF-CEM cells as target cells. This method is based on loading target cells with an acetoxymethyl ester of fluorescence enhancing ligand (BATDA) which quickly penetrates the cell membrane. Within the cell the ester bonds are hydrolysed to form a hydrophilic ligand (TDA) which no longer passes the membrane. After cytolysis, the ligand is released and can be detected by addition of Europium which forms with the TDA a highly fluorescent and stable chelate (EuTDA). The measured signal correlates directly with the amount of lysed cells.
-
Isolation of Mononuclear Cells from Human Peripheral Blood:
-
Leukocyte cones were collected from healthy donors and their content was diluted up to 50 ml with phosphate buffered saline (PBS, from Gibco) and layered into 2 centrifuge tubes on top of 15 mL Ficoll-Paque (from GE Healthcare). PBMC were separated by density gradient centrifugation (400 g for 40 min without brake), transfer in a clean centrifuge tube and then wash with 50 mL PBS, twice by centrifuging at 300 g for 5 min and twice by centrifuging at 200g for 5 min. PBMC were then resuspended in R10 media (RPMI+10% heat-inactivated Fetal Bovine Serum, both from Gibco) and their cell count and viability assess with EVE™ Automated Cell Counter (from NanoEnTek).
ADCC Assay Methods:
-
Labelling of target cells was performed according to manufacturer's instruction. Briefly, CCRF-CEM cells were resuspended at 1×106/mL in assay media (RPMI+10% ultra-low IgG FBS, from Gibco) and loaded with 5 μl/mL of Delfia BATDA reagent (Perkin Elmer) for 30 min at 37° C. Cells were then washed 3 times with 50 mL PBS (300 g for 5 min) and resuspended at 8×105/ml (3×) in assay media.
-
STIM001_289, STIM003_289, STIM001, STIM003 and their isotype controls, IgG1_289 and IgG1 were serially diluted 1:4 in assay media to give final 3× antibody concentrations ranging from 30 nM to 0.12 μM (10-point curve).
-
NK cells were negatively isolated from PBMC using the EasySep Human NK Cell Isolation Kit (from Stemcell Technologies) and resuspended at 4×106/ml (3×) in assay media.
-
BATDA-loaded CCRF-CEM and primary NK cells were co-cultured for 4-hours at 37° C. and 5% CO2 at a 5:1 Effector:Target ratio in assay media in the presence of the antibodies under investigation (from 10 nM to 0.04 μM final concentration). Wells containing CCRF-CEM cells only or CCRF-CEM+Delfia lysis buffer (Perkin Elmer) were used to determine spontaneous and 100% BATDA release, respectively. Cell-free supernatants were then transferred into a DELFIA Microtitration Plates and incubated for 15 min at Room Temperature with the Delfia Europium solution (Perkin Elmer). Fluorescent signal at 615 nM was then quantified with Envision Multilabel Reader (Perkin Elmer).
-
Specific dye release induced by the Abs was calculated as: [(Experimental release−Spontaneous release)/(Maximum release−Spontaneous release)]*100.
-
This experiment was repeated with NK-cells from 2 independent donors and 3 technical replicates were included for each assay condition.
Results:
-
The ability of STIM001_289 and STIM003_289 bispecific antibodies to induce ADCC was assessed using primary NK cells from 3 independent donors, as effector cells and ICOS-transfected CCRF-CEM as target cells. STIM001 and STIM003 and the relevant isotype controls (IgG1 and IgG1_289) were run in the same experiments. Target cells were loaded with BADTA dye and incubated for 4 hrs either alone (spontaneous release), with lysis buffer (100% release) or with NK cells plus increasing concentration of antibody. Dye release correlates directly with the number of lysed cells. Data are showed as % of specific dye release and plotted against the log of antibody concentrations (FIG. 9 ). In all donors, STIM001_289, STIM003_289, STIM001 and STIM003 increased the % of specific dye release in a concentration dependent manner. Non-linear regression curves (variable slope, 4-parameter) were extrapolated from the data obtained. These data demonstrate that the bispecific constructs have the ability to kill ICOS positive cells in a primary NK dependent ADCC assay. The EC50s of the bispecific antibodies in the ADCC assay were comparable to those of STIM001 and STIM003 monoclonal IgG1 antibodies. See Table E5-2 and FIG. 9 A-C.

Example 6 Ability of ICOS/PD-L1 Bispecific Antibody to Neutralise ICOS Binding to ICOS Ligand
-
Anti-ICOS antibodies in monoclonal and mAb2 format were assessed for ICOS ligand (B7-H2) neutralisation using HTRF. These antibodies are capable of neutralising both human and mouse ICOS B7-H2 ligand and were assessed in both Human ICOS Receptor/Human Ligand and Mouse ICOS Receptor/Mouse Ligand HTRF based Neutralisation assays.
Method:
-
Antibodies were diluted in assay buffer (0.53M Potassium Fluoride (KF), 0.1% Bovine Serum Albumin (BSA) in 1×PBS) from a starting working concentration of either 1 μM or 0.4 μM and serially diluted 1 in 3 over 11 points. 5 μl of titrated antibody were added to 384w solid white assay plate (Greiner Bio-One). Positive and negative control wells received 5 μl of assay buffer only.
-
5 μl of human ICOS-mFc (Chimerigen) at 20 nM (5 nM final) or 5 ul of mouse ICOS-mFc (Chimerigen) at 4 nM (1 nM final) were added to relevant assay wells. Plate was incubated for 1 hour (hr) at room temperature (RT).
-
After incubation, 5 μl of ICOS ligand, (B7-H2, R&D Systems) conjugated to Alexa 647 (Innova Bioscience) was diluted to either 14.08 nM (3.52 nM final) for human B7-H2 or 36.08 nM (9.02 nM final) for mouse B7-H2 and added to all wells of assay plate except negative control wells which instead received 5 ul of assay buffer.
-
Finally, 5 μl of 4.32 nM anti-mouse IgG donor mAb (Southern Biotech) labelled with europium cryptate (Cis Bio), was added to each well and the assay was left in the dark at RT to incubate for a further 2 hours. After incubation, assay was read on Envision plate reader (Perkin Elmer) using a standard HTRF protocol. 620 nm and 665 nm channel values were exported to Microsoft Excel and % Delta-F and % Neutralisation calculations performed. Titration curves and IC50 values [M] were plotted using Graphpad (Prism). IC50 values were calculated by first transforming the data using equation X=Log(X). The transformed data was then fitted using nonlinear regression, using fitting algorithm, log (inhibitor) vs. response-variable slope (four parameters).

Results:
-
In the human ICOS ligand neutralisation system, STIM003_289 and STIM003_457 produced similar IC50 values to STIM003 (mean 1050 values, 0.81±0.28 nM, 0.56±0.18 nM and 0.53±0.15 nM respectively).
-
In the human ICOS ligand neutralisation system, STIM001_289 and STIM001_457 produced similar IC50 values to STIM001 (mean 1050 values, 2.0±1.7 nM, 1.6±6.9 nM and 1.5±0.75 nM respectively).
-
In the mouse ICOS ligand neutralisation system, STIM003_289 and STIM003_457 produced similar IC50 values to STIM003 (mean 1050 values, 0.14±0.037 nM, 0.11±0.027 nM and 0.12±0.027 nM and respectively).
-
In the mouse ICOS ligand neutralisation system, STIM001_289 and STIM001_457 produced similar IC50 values to STIM001 (mean 1050 values, 4.8±1.7 nM, 5.16±1.5 nM and 8.7±6.6 nM and respectively).
-
In the human ICOS ligand neutralisation system, STIM003 produced similar IC50 values to STIM001 (mean 1050 values, 0.53±0.15 nM, 1.5±0.75 nM respectively).
-
In the mouse ICOS ligand neutralisation system, STIM003 produced more potent IC50 values to STIM001 (mean IC50 values, 0.12±0.027 nM and 8.7±0.66 nM respectively).

Example 7 Ability of ICOS/PD-L1 Bispecific Antibody to Neutralise PD-L1 Binding to PD1 or CD80
Neutralisation of Human PD-L1 Binding
-
Bispecific mAb2 antibodies STIM001_289 and STIM003_289, two anti-PD-L1 antibodies AbW and AbV, and one isotype control (IgG1_289), were assessed for ability to neutralise human PD-L1 binding to its receptors human PD1 and human CD80 on CHO cells, using flow cytometry (FACS). Ability of the mAb2 to neutralise binding of human PD-L1 to its receptors was confirmed in this assay.
Method:
-
CHO-S cells untransfected (referred to as WT) or transfected with human PD-L1 were diluted in FACS buffer (PBS+1% w/v BSA+0.1% w/v sodium azide) and were distributed to a 96-well V-bottom plate (Greiner) at a density of 5×104 cells per well. Biotinylated human CD80-Fc (R&D Systems) or PD-1-Fc were prepared as a standard curve titration from 1 μM final assay concentration (FAC), ⅓ dilution series in FACS buffer. Antibody and mAb2 titrations were prepared from 396 nM working concentration, 198 nM FAC, as a ⅓ dilution series in FACS buffer. Biotinylated PD-1 or CD80 were diluted in FACS buffer to 80 nM working concentration, 40 nM FAC. Plates were centrifuged at 300×g for 3 minutes to supernatant aspirated. 25 μL receptor and 25 μL mAb2 solution (or 50 μL of receptor standard curve titration) were added to cells and incubated at 4° C. for 1 hour. Cells were washed with 150 μL of PBS and centrifuged at 300 g for 3 minutes. Supernatant was aspirated and 150 μL PBS added. This wash step was repeated. Presence of bound CD80 or PD-1 was detected by addition of 50 μL of streptavidin-AlexaFluor 647 (Jackson ImmunoResearch) diluted 1/500 in FACS buffer to each well. Cells were incubated 1 hr at 4° C. in the dark. Cells were washed as previously described. To fix cells, 100 μL 4% v/v paraformaldehyde was added and cells incubated for 20 minutes at 4° C., cells were pelleted by centrifugation at 300×g and the plates resuspended in 100 μL FACS buffer. AlexaFluor 647 signal intensity (geometric mean) was measured by flow cytometry using a Beckman Coulter CytoFLEX.

Neutralisation of Mouse PD-L1 Binding
-
Ability of the ICOS/PD-L1 bispecific antibody to neutralise binding of mouse PD-L1 to its receptors was confirmed in this assay.
Method:
-
CHO-S cells untransfected (referred to as WT) or transfected with mouse PD-L1 were diluted in FACS buffer (PBS+1% w/v BSA+0.1% w/v sodium azide) and were distributed to a 96-well V-bottom plate (Greiner) at a density of 5×104 cells per well. Biotinylated mouse PD-1-Fc (R&D Systems) or CD80-Fc (R&D Systems) were prepared as a standard curve titration from 1 μM final assay concentration (FAC), ⅓ dilution series in FACS buffer. Antibody and mAb2 titrations were prepared from 44 nM working concentration, 22 nM FAC, as a ⅓ dilution series in FACS buffer. Biotinylated PD-1 or CD80 were diluted in FACS buffer to 80 nM working concentration, 40 nM FAC. Plates were centrifuged at 300×g for 3 minutes to supernatant aspirated. 25 μL receptor and 25 μL mAb2 solution (or 50 μL of receptor standard curve titration) were added to cells and incubated at 4° C. for 1 hour. Cells were washed with 150 μL of PBS and centrifuged at 300 g for 3 minutes. Supernatant was aspirated and 150 μL PBS added. This wash step was repeated.

-
STIM001_457, STIM003_457 and IgG1_438 produced similar IC50s (0.35±0.09 nM, 0.40±0.13 nM, and 0.34±0.05 nM respectively) using the PD-L1 and PD1 neutralising system. These mAb2s also neutralised PD-L1 binding to CD80 (1050, 0.9±0.03 nM, 0.29±0.0002 nM and 0.27±0.06 nM respectively).

Monoclonal antibodies STIM001, STIM003 and IgG1 control did not neutralise mouse PD-L1 binding to mouse PD1 or mouse CD80.
Example 8 Effect of ICOS/PD-L1 Bispecific Antibody on T Cells in ICOS-Dependent Activation Assay
-
The agonistic potentials of STIM001_289 and STIM003_289 bispecific antibodies in this assay were compared with those of STIM001 and STIM003 monoclonal antibodies in a human primary T-cell activation assay where anti-CD3 and anti-CD28 antibodies were added concurrently to induce ICOS expression on effector T-cells. Effect of the ICOS co-stimulation on the level of IFN-γ produced by these activated T-cells were assessed using ELISA at 72 hrs post-activation. This assay is used to confirm activity of the ICOS-binding portion of the bispecific antibody. Retention of ability to induce ICOS-mediated T cell activation was confirmed for anti-ICOS antibodies STIM001 and STIM003 in the ICOS/PD-L1 mAb2 bispecific format in which the Fcab region binds human PD-L1.
Methods:
-
PBMC were isolated from human peripheral blood as described in Example 5c and stored in nitrogen for further utilisation.
-
STIM001_289, STIM003_289, STIM001, STIM003 and their isotype controls, IgG1_289 and IgG1 were serially diluted 1:3 in PBS to give final antibody concentrations ranging from 10 μM to 40 nM (6-point curve). 100 μL of diluted antibodies were coated in duplicate into a 96-well, high-binding, flat-bottom plate (Corning EIA/RIA plate) overnight at 4° C. Plate was then washed with PBS. In some experiments an anti-PD-L1 antibody, AbV, was added at the same concentrations.
-
T-cells were negatively isolated from frozen PBMC using the EasySep Human T Cell Isolation Kit (from Stemcell Technologies) and resuspended at 2×106/ml in R10 media supplemented with 40 μl/ml of Dynabeads Human T-Activator CD3/CD28 (from Life Technologies).
-
T-cell suspensions were added to antibody-coated plates to give a final cell concentration of 1×106 cells/ml and cultured for 72 hrs at 37° C. and 5% CO2. Cell free supernatants were then collected and kept at minus 20° C. until analysis of secreted IFN-γ by ELISA with the R&D Systems™ Human IFNγ Duoset® ELISA, using DELFIA® Eu-N1 Streptavidin detection.
-
This experiment was repeated on T-cells isolated from 4 independent donors and 2 technical replicates were included for each assay condition.
Results:
-
The levels of IFN-γ induced by STIM001_289, STIM003_289, STIM001, STIM003 and their isotype controls (IgG1_289 and IgG1) were measured in assay replicates and plotted as mean value±Standard Deviation (SD) against the log of antibody concentrations, as showed for one donor (FIGS. 13 , A and B). All antibodies increased the levels of IFN-γ in a concentration dependent manner. In some experiments, anti-PD-L1 AbV was added as the same concentration and did not modify the levels of IFN-γ. Non-linear regression curves (variable slope, 4-parameter) were extrapolated from data obtained with 4 independent donors (EC50 values in Table E8). Both STIM001_289 and STIM003_289 increased the IFN-γ levels to the same extent as STIM001 and STIM003 respectively. Both EC50 values (Table E8) and levels of IFN-γ at the plateau (3.3 μM, FIG. 13 C) were comparable for STIM001 vs STIM001_289 and for STIM003 vs STIM003_289 (median values). These data demonstrate that the ICOS binding sites of the anti-ICOS monoclonal antibodies have conserved their ICOS agonistic effect on human primary T-cells when included in the ICOS/PD-L1 bispecific antibodies.

Example 9 Effect of ICOS/PD-L1 Bispecific Antibody on T Cell Activation in Monocvte Co-Culture Primary Cell Assay
-
This assay can be used to assess ability of the PD-L1 binding site of the bispecific antibody to block PD-L1 PD1 interaction and thereby promote activation of T cells in autologous co-culture of T and B lymphocytes from peripheral blood samples. The effects of STIM001_289, STIM003_289 and IgG1_289 mAb2 antibodies on IFN-γ production were compared to those of anti-PD-L1 AbV, STIM003 and IgG1 monoclonal antibodies in a co-culture of purified peripheral blood monocytes and CD45RO+ memory T-cells from the same donor. These cultures were done in the presence of anti-CD3 antibody to provide TCR stimulation. Retention of ability to promote T cell activation in this assay was confirmed for STIM001 and STIM003 in the ICOS/PD-L1 mAb2 bispecific format in which the Fcab region binds human PD-L1. The control PD-L1 mAb2, lacking an ICOS binding site, was inactive in this assay.
Methods:
-
PBMC were isolated from human peripheral blood as described in Example 5c and stored in nitrogen for further utilisation.
-
STIM001_289, STIM003_289, IgG1_289, anti-PD-L1 AbV, STIM003 and their isotype control IgG1 were serially diluted 1:4 in R10 media to give final 4× antibody concentrations ranging from 40 nM to 40 μM (6-point curve). Anti-human CD3 (clone UCHT1 from eBioscience) was diluted in R10 media to a 4×Ab concentration of 2 μg/ml.
-
Monocytes and memory cells were isolated from frozen PBMC from the same donor. Monocytes were negatively isolated using the Pan Human Monocyte Isolation Kit (Miltenyi biotec) and resuspended at 2×106/ml (4×) in R10 media. CD45RO+ T-cells were isolated by a first round of negative selection for CD3+ T cells (Pan T-cell isolation kit, Miltenyi Biotec), followed by a positive selection for CD45RO+ cells (Human CD45RO MicroBeads, Miltenyi Biotec). CD45RO+ T-cells were then resuspended at 2×106/ml (4×) in R10 media. Cell subsets were co-cultured for 4-days at 37° C. and 5% CO2 at a 1:1 ratio in R10 media in the presence of anti-CD3 (0.5 μg/ml final concentration) and the antibodies under investigation (from 10 nM to 10 μM final concentration). In some wells, no antibody under investigation was added to be able to quantify the basal IFN-γ level (Monocytes+T-cells+CD3 only). After 4-days culture, cell-free supernatants were analysed for IFN-γ release with the R&D Systems™ Human IFNγ Duoset® ELISA, using DELFIA® Eu-N1 Streptavidin detection. Fold increase in IFN-γ was calculated as: (Experimental IFN-γ level/Basal IFN-γ level) This experiment was repeated with monocytes and T-cells isolated from 7 independent donors and 3 to 5 technical replicates were included for each assay condition (dependent of the number of cells available).
Results:
-
The levels of IFN-γ induced by STIM001_289, STIM003_289, IgG1_289, STIM003, PD-L1 AbV and their isotype control (IgG1) were measured in assay replicates and plotted as mean value±standard deviation (SD) against the log of antibody concentrations, as shown for one donor (FIG. 14 ). Unlike STIM003, the antibodies binding PD-L1 such as STIM001_289, STIM003_289, IgG1_289 and anti-PD-L1 AbV all increased the levels of IFN-γ in a concentration dependent manner. This experiment was repeated in 7 independent donors and high variability in IFN-γ production was noticed in absence of antibody under investigation: 311±177 μg/mL (mean±SD, n=7). Levels of IFN-γ obtained were then normalized by the production of IFN-γ in absence of antibody under investigation. The maximum increase in IFN-γ (values at 10 nM) for all 7 donors was plotted and analysed using Friedman statistic test (FIG. 14 ). The mean increase in IFN-γ level compared to the isotype control (IgG1) induced by was significant for anti-PD-L1 AbV, STIM003_289 and STIM001_289 and was close to significance for IgG1_289 which also binds to PD-L1. Altogether this data is confirming that the PD-L1 binding sites in the bispecific antibodies retain ability to block PD-1/PD-L1 interaction and can subsequently activate T cells.
Example 10 Anti-Tumour Efficacy of ICOS/PD-L1 Bispecific Antibody on J558 Myeloma in Vivo
-
The J558 syngeneic tumour model was used to assess the effect of bispecific anti-ICOS/anti-PD-L1 antibodies on myeloma. Two ICOS/PD-L1 mAb2 bispecific antibodies, STIM001_457 and STIM003_457, were tested in Balb/c mice using the sub-cutaneous J558 plasmacytoma:myeloma cell line (ATCC, TIB-6), to determine how STIM001_457 hIgG1 and STIM003_457 hIgG1 affect the growth of the tumour.
Method:
-
Balb/c mice were supplied by Charles River UK at 6-8 weeks of age and >18g and housed under specific pathogen-free conditions. A total of 5×106 cells (passage number below P15) were subcutaneously injected (in 100 μl) into the right flanks of mice. Unless stated otherwise, on day 11 post tumour cells injection, the animals were randomised based on tumour size and treatments were initiated. The J558 cells were passaged in vitro by using TrypLE™ Express Enzyme (Thermofisher), washed twice in PBS and resuspended in DMEM supplemented with 10% foetal calf serum. Cell viability was confirmed to be above 90% at the time of tumour cell injection.
-
Treatment was initiated when the tumours reached an average volume of ˜140 mm{circumflex over ( )}3. Animals were then allocated to 3 groups with similar average tumour size (see Table E10-1 below for the dosing groups). Both bispecific antibodies recognise mouse ICOS (Fab portion) and mouse PD-L1 (Fcab portion) and were dosed IP (dosed at 200 ug per dose) from day 11 (post tumour cell implantation) twice a week for 3 weeks unless the animals had to be removed from study due to welfare (rare) or tumour size. As a control, a group of animals (n=10) was dosed at the same time using a saline solution. Tumour growth was monitored over 37 days and compared to tumours of animals treated with saline. Animal weight and tumour volume were measured 3 times per week from the day of tumour cell injection. Tumour volume was calculated by use of the modified ellipsoid formula ½(Length×Width2). Mice were kept on studies until their tumour reached an average diameter of 12 mm3 or, rarely, when incidence of tumour ulceration was observed (welfare).

Results:
-
The J558 syngeneic model is highly aggressive. All animals in the saline control group (n=10) had to be removed from studies by day 21 due to tumour size. However, both bispecific antibodies STIM001_457 and STIM003_457 demonstrated good efficacy when used as the sole therapy in this model with, respectively, 50% and 62.5% of the animals cured from their disease by day 37. The anti-tumour efficacy of both bispecific antibodies resulted in improved overall survival of the treated animals (time on study) which was significant vs saline treated group for both antibodies (p<0.05 for STIM003_457 and p<0.001 for STIM001_457). See FIG. 15 and FIG. 16 . Table E10-2 below shows hazard ratio (logrank) and p value for the different treatment comparisons.

This example demonstrates strong anti-tumour efficacy in vivo in a CT-26 syngeneic model by co-targeting ICOS and PD-L1 using a bispecific antibody. Bispecific mAb2 STIM001_457 hIgG1 and STIM003_457 hIgG1 were both effective in this study.
Method:
-
Efficacy studies were performed in BALB/c mice using the sub-cutaneous CT-26 colon carcinoma model (ATCC, CRL-2638). BALB/c mice were supplied by Charles River UK at 6-8 weeks of age and >18g and housed under specific pathogen-free conditions. A total of 1×10E5 CT-26 cells (passage number below P20) were subcutaneously injected into the right flanks of mice. Unless stated otherwise, treatments were initiated at day 6 post tumour cells injection. The CT-26 cells were passaged in vitro by using TrypLE™ Express Enzyme (Thermofisher), washed twice in PBS and resuspended in RPMI supplemented with 10% foetal calf serum. Cell viability was confirmed to be above 90% at the time of tumour cell injection.
-
STIM001_457 or STIM003_457 bispecific mAb2 antibody was each used as the sole therapeutic agent. These antibodies bind to mouse ICOS via the Fab domains and to mouse PD-L1 via the Fc domain (Fcab). Bispecific antibodies were dosed intraperitoneal (IP) at 200 μg each (1 mg/ml in 0.9% saline) three times per week from day 6 (dosing for 2 weeks between day 6-17) post tumour cell implantation. Tumour growth was monitored and compared with tumours of animals in a saline-treated control group and with an isotype IgG1_457 control mAb2 antibody which binds to mouse PD-L1 but does not bind to ICOS. Animal weight and tumour volume were measured 3 times per week from the day of tumour cell injection. Tumour volume was calculated by use of the modified ellipsoid formula ½(Length×Width2). Mice were kept on studies until their tumour reached an average diameter of 12 mm3 or, rarely, when incidence of tumour ulceration was observed (welfare). Mice were re-challenged at day 50. The humane endpoint survival statistics were calculated using the Kaplan-Meier method with Prism. This approach was used to determine if specific treatments were associated with improved survival.

Results:
-
The present experiment clearly demonstrates that both bispecific antibodies significantly delayed tumour growth and extended the survival (time to reach humane endpoint/time on study) of treated animals when compared to saline or IgG1_487 LAGA treated animals. When administered individually as monotherapies rather than in combination, anti-ICOS and anti-PD-L1 antibodies were each significantly less effective at preventing CT26 tumours compared with the bispecific antibodies (data not shown).
-
In this experiment STIM003_457 antibody was more effective at inhibiting tumour growth than STIM001_457. STIM003_457 demonstrated the strongest anti-tumour efficacy and improved survival (60% were cured from the disease at day 50) whereas STIM001_457 resulted in 3 out 10 animals (30%) with no sign of disease at the end of the study (day 50). See FIG. 17 .

These data confirm that co-targeting ICOS and PD-L1 using a bispecific antibody, even as the sole treatment agent, is effective to trigger an anti-tumour response in the CT26 model.
Example 11 b Treatment with Bispecific ICOS/PD-L1 Antibody Induces Long-Term Immune Memory to Tumour Antigens
-
Animals that showed full tumour regression following treatment with the bispecific antibodies in Example 11a were challenged again with tumour cells. Of a total of 9 animals, 5 were re-challenged with CT26 to determine whether the animals' immune system showed a memory response to CT26 cells that could prevent these tumours from growing post re-challenge implantation. In addition, 4 animals were challenged with implanted EMT-6 tumour cells, which their immune systems had not been exposed to previously.

Results are shown in FIG. 19 . All the animals that had rejected the CT-26 tumours in response to one of the two ICOS/PD-L1 bispecifics managed to reject the newly-injected CT-26 cells in the absence of further treatment. On the other hand, animals that were injected with the new cell line EMT-6, all quickly demonstrated the presence of an established EMT-6 tumour. Altogether the data demonstrate that animals that previously rejected CT-26 tumour in response to either of the bispecific antibody treatments were fully resistant to the CT-26 tumour but not to the unrelated EMT6 tumour. This result indicates that the mice cured by the bispecific antibody therapy had established a long-term memory to tumour antigens expressed specifically by the CT-26 tumour.
Example 12 Anti-Tumour Efficacy of ICOS-PD-L1 Bispecific Antibody on A20 Tumours In Vivo
-
ICOS/PD-L1 bispecific antibodies STIM001_457 and STIM003_457 showed strong anti-tumour efficacy in vivo in the A20 syngeneic model when used as sole therapy.
Method:
-
Efficacy studies were performed in BALB/c mice using the sub-cutaneous A20 Reticulum Cell Sarcoma model (ATCC number CRL-TIB-208). BALB/c mice were supplied by Charles River UK at 6-8 weeks of age and >18g and housed under specific pathogen-free conditions. A total of 5×10E5 A20 cells (passage number below P20) were subcutaneously injected into the right flanks of mice. Unless stated otherwise, treatment was initiated at day 8 post tumour cells injection. The A20 cells were passaged in vitro by using TrypLE™ Express Enzyme (Thermofisher), washed twice in PBS and resuspended in RPMI supplemented with 10% foetal calf serum. Cell viability was confirmed to be above 85% at the time of tumour cell injection.
-
The antibodies were dosed intraperitoneally (IP) at 200 μg each (1 mg/ml in 0.9% saline) twice per week from day 8 (dosing for 3 weeks between day 8-25, six doses in total) post tumour cell implantation. Tumour growth was monitored and compared to tumours of animals treated with a IgG2a isotype control group and IgG1_457 (anti-PD-L1 control). Animal weight and tumour volume were measured 3 times a week from the day of tumour cell injection. Tumour volume was calculated by use of the modified ellipsoid formula ½(Length×Width2). Mice were kept on study until their tumour reached an average diameter of 12 mm3 or, rarely, when incidence of tumour ulceration was observed (welfare).

Results:
-
The STIM001_457 and STIM003_457 bispecific antibodies significantly delayed the growth of A20 sub-cutaneous tumours and resulted in extended survival (time to reach humane endpoint) of the treated animals when compared to IgG2a isotype control or IgG1_487 treated animals. All animals in the two control groups had to be removed from the study by day 40. Notably, both bispecific antibodies demonstrated a strong anti-tumour efficacy with 40 and 70% of the animals presented no signs of the disease at day 41. See FIG. 20 and FIG. 21 .
Example 13 Anti-Tumour Efficacy of ICOS/PD-L1 Bispecific Antibody on EMT6 Tumours In Vivo
-
Anti-tumour in vivo efficacy of co-targeting ICOS and PD-L1 with bispecific antibodies was assessed in an EMT-6 syngeneic model using STIM001_457 and STIM003_457.
Method:
-
Efficacy studies were performed in BALB/c mice using the sub-cutaneous EMT-6 breast carcinoma model (ATCC number CRL-2755). BALB/c mice were supplied by Charles River UK at 6-8 weeks of age and >18g and housed under specific pathogen-free conditions. A total of 2.5×10E5 EMT-6 cells (passage number below P20) were subcutaneously injected into the right flanks of mice. Unless stated otherwise, treatments were initiated at day 6 post tumour cells injection. The EMT-6 cells were passaged in vitro by using TrypLE™ Express Enzyme (Thermofisher), washed twice in PBS and resuspended in Waymouths MB 752/1 with 2 mM L-glutamine and supplemented with 15% foetal calf serum. Cell viability was confirmed to be above 90% at the time of tumour cell injection.
-
STIM001_457 and STIM003_457 were each used as single therapeutic agents, dosed intraperitoneally (IP) at 200 μg (1 mg/ml in 0.9% saline) twice a week from day 6 (dosing for 3 weeks between day 6-23) post tumour cell implantation. Tumour growth was monitored and compared to tumours of control animals treated with a saline and IgG1_457 LAGA control. IgG1_457 LAGA can bind PD-L1 and block PD1-PD-L1 interaction but does not bind to ICOS. Animal weight and tumour volume were measured 3 times per week from the day of tumour cell injection. Tumour volume was calculated by use of the modified ellipsoid formula ½(Length×Width2). Mice were kept on studies until their tumour reached an average diameter of 12 mm3 or, rarely, when incidence of tumour ulceration was observed (welfare).

Results:
-
Data are shown in FIG. 22 and FIG. 23 , and in Table E13-2 below.
-
Both bispecific antibodies significantly delayed EMT6 tumour growth and resulted in a longer survival (time to reach humane endpoint) when compared with animals treated with saline or IgG1_457 LAGA. STIM001_457 was marginally more potent in this model and resulted in the strongest anti-tumour efficacy and improved survival (30% vs 20% were cured from the disease at day 44 for STIM001_457 and STIM003_457, respectively), however this difference is not significant. Interestingly the IgG1_457 LAGA treatment resulted in tumour growth delay (vs saline treated group) but unlike what was observed for the ICOS/PD-L1 bispecific, this efficacy did not result in complete response (i.e., absence of tumour at the end of the experiment).
