Definitions

  • SARS-CoV-2 severe acute respiratory syndrome coronavirus 2
  • SARS-CoV-2 genomic RNA contains a large viral replicase gene, genes encoding non-structural proteins at its 5’ end, and a region encoding four major structural and multiple accessory proteins at the 3’ end.
  • Structural proteins include Spike or Surface glycoprotein (S), Membrane protein (M), Envelope protein (E) and Nucleocapsid protein (N) [Fehr & Perlman 2015].
  • the membrane surface glycoprotein S consists of two subunits, S1 and S2, that mediate viral binding to the host receptor ACE2 and fusion with the host cell membrane, respectively.
  • the S1 subunit contains the receptor binding domain (RBD) that directly interacts with ACE2 and is a target of multiple neutralizing antibodies currently in clinical trials [Lan et al. 2020, Robbiani et al. 2020].
  • RBD receptor binding domain
  • the vast majority of the ongoing efforts are all targeting the S protein.
  • Both passive (therapeutic antibodies) and active (vaccine) approaches directed at S protein are expected to promote virus neutralization, that is, inhibition of viral entry into healthy cells.
  • Variants of Interests which are defined as having specific genetic markers that are predicted to affect transmission, diagnostics, therapeutics, or immune escape. Data also demonstrates these variants of interest were the cause of an increased proportion of cases or outbreak, but they are of limited prevalence in the US or other countries (https://www.cdc.gov/coronavirus/2019-ncov/cases- updates/variant-surveillance/variant-info.html#Concern). [0007] Studies are described herein that elucidate the memory B cell antibody response in convalescent patients, using an approach that enables the generation of large, stable hybridoma libraries from primary human B cells.
  • Hybridoma libraries were generated from the memory B cells of convalescent COVID-19 blood donors who were eligible to donate convalescent plasma based upon their high titer of IgG antibodies against the SARS-CoV-2 virus. Monoclonal antibodies derived from those libraries were selected on the basis of their selective binding to one of multiple SARS-CoV-2 proteins used as targets in both cell-based and soluble protein-based screens. Characterization of these antibodies revealed broad responses to diverse viral antigens. Fewer than half of the antibodies were directed at S protein, while the remainder were directed at other viral proteins including N and ORF-encoded proteins.
  • anti-Spike antibodies were directed at highly diverse SARS-CoV-2 antigens, they were generally characterized as having variable levels of somatic hypermutation (SHM) and a diversity of VH and VL gene usage.
  • Functional properties of anti-Spike antibodies were successfully confirmed against reference strains (e.g., USA/WA_CDC-WA1/2020), as well as multiple variants including the CDC variants of concern, in series of tests ranging from in vitro neutralization of both pseudovirus and live virus isolates to in vivo neutralization activity in a hamster model of COVID-19.
  • Three anti-Spike antibodies were identified that when mixed together in a cocktail exhibited combinatorial effects against those variants.
  • kits for treating a SARS-CoV-2 infection in an immunocmpromised subject comprising administering to the subject at least first and send antibodies or antigen binding fragmetns thereof that specifically bind to distinct epitopes of a Spike protein a Spike protein of SARS-CoV-2, wherein the first antibody or antigen binding fragment thereof binds to an epitope in an ACE2 receptor binding site of the Spike protein and the second antibody or antigen binding fragment thereof binds to an epitope outside of the ACE2 receptor binding site of the Spike protein.
  • the antibodies disclosed herein are especially effective for treating immunocompromised individuals due to synergistic effects and their ability to fix complement.
  • the antibodies are able to effectively fix complement due to their specific binding sites on the Spike protein and orientation of binding.
  • the methods provided herein are effective for viral clearance in immunocompromised patients.
  • the methods provided herein are effective for treatment of individual who have decreased adaptive immune system function.
  • Also provided herein are methods of treating a SARS-CoV-2 infection in a subject comprising administering about 200 mg, about 400 mg, about 600 mg, or about 800 mg of one, two, three, or four antibodies or antigen binding fragments provided herein.

Whereas other naturally occurring mutations, such as L452R, E484Q, or D614G do not impact binding relative to binding to the Washington reference Spike protein. In contrast, binding of PR193_0018 and PR200_00622 are not significantly impacted by any of the single point mutations tested.
  • binding by PR193_0018 and PR200_00622 to specific variant Spike proteins appears to be modestly enhanced over the reference Spike.
  • Similar observations were made when binding of PR193_0018, PR194_00232, and PR200_00622 was tested against RBD domain proteins containing the full complement of mutations known to exist in four different variants. Of particular interest is the binding to RBDs corresponding to the South African (B.1.351) and U.K. (B.1.1.7) variants. As predicted by the K417N and N501Y single point mutation data, binding of PR194_00232 to both the U.K. and S.A. variants is weaker than observed against the reference strain Spike protein.
  • Identified anti-Spike antibodies bind to non-overlapping epitopes within the RBD of SARS-Co-V-2 Spike.
  • Purified recombinant forms of the PR193_00018, PR194_00232, and PR200_00622 failed to compete with each other for binding to the SARS-CoV-2 RBD when assessed via biolayer interferometry on an Octet QKe instrument.
  • These data suggested the three antibodies bind to non-overlapping epitopes on the SARS- CoV-2 RBD.
  • Alanine scanning of the RBD was performed to identify residues critical for binding of each of the antibodies. Consistent with each of the antibodies binding to non- overlapping epitopes, non-overlapping sets of residues were identified as being critical for binding of the antibodies (Table 5).

  • B.1.617.2 delta
  • B.1.617.3 kappa
  • C.37 lambda
  • IMM20190 binds to a large epitope that encompasses two distinct regions on the RBD (FIG. 2).
  • K417 and N501 residues known to be mutated in different variants, represent residues in each of the two binding sites. Mutation of one of those sites (N501Y), as observed in the alpha/B.1.1.7 variant, is sufficient to maintain IMM20190 activity (FIGS. 5A-5C) and provides for improved synergy with IMM20184/IMM20253.

  • PRA pseudovirus neutralization assays
  • Assays using the Germany/BavPat1/2020 strain were performed in a manner sufficient to assess combinatorial effects via the HSA algorithm. Data demonstrated an overall additive effect, with peak HSA scores reaching levels of synergy (FIG. 7B)
  • Example 10 Example 10.
  • Abs neutralize virus in a hamster model of SARS-CoV-2 Antibodies capable of neutralizing live virus in vitro were assessed for the ability to neutralize virus in vivo using a hamster model of SARS-CoV-2 infection.
  • Hamsters treated with increasing doses of PR194_00232 were infected with SARS-CoV-2 (SARS-CoV- 2/human/USA/WA_CDC-WA1/2020) and viral load in the lungs were assessed at Day 4 post inoculation of the virus using standard tissue culture infectivity assays and plaque counting.
  • PR194_00232 was able to neutralize virus, relative to no-treatment controls, in a dose- dependent manner when dosed in the prophylactic setting (FIG. 12).
  • IMM-BCP-01 is able to clear virus from the lungs of hamsters infected with variants of concern. Hamsters were dosed prophylactically with IMM-BCP-01 one day prior to inoculation with either the Alpha (FIG. 16A) or Beta (FIG.
  • IMM-BCP-01 at the lowest doses tested provided levels of viral clearance that match, or exceed, those obtained by antibodies with demonstrated clinical efficacy.
  • increased doses of IMM-BCP-01 led to a dose- dependent improvement in viral clearance, with > four-log clearance of WA1/2020 and 2.5 log clearance of Beta at the highest doses tested. All doses tested represent clinically relevant doses.
  • Robust activity of the cocktail was observed regardless of inoculation titer used (FIG. 17).
  • IMM20184, IMM20190, and IMM20253 bind to both isolated RBD and Spike trimer when assessed by surface plasmon resonance (FIGS. 18A-18C).
  • IMM20184 can bind avidly to the Spike trimer, as signified by the decrease off-rate (Table 7), and crosslink two Spike monomers.
  • IMM20190 Consistent with its epitope overlapping with the ACE2 binding site, IMM20190 is able to compete binding of ACE2 to isolated RBD protein from the REF and Alpha variant (FIG. 19A and FIG. 19B), but its ability to compete ACE2 binding to the Beta variant is decreased (FIG.
  • IMM20184 effectively competes binding of ACE2 to all three isolated RBD (FIGS. 19A – 19C), despite binding to an epitope that is outside of known ACE2 binding site (FIG. 2). Despite exhibiting neutralization activity against both pseudovirus and live virus, IMM20253 is unable to effectively compete for ACE2 binding (FIGS. 19A-19C). This suggests the neutralization is due to a mechanism distinct from direct ACE2 competition. [0223] IMM20184, IMM20190 and IMM20253 were assessed for the ability to fix complement using standard assays [Nikitin et al., 2019]. As depicted in FIGS.
  • IMM-BCP-01 exhibited enhanced activity, over a wider concentration range, as compared to any of the individual antibodies and the IMM20184/IMM20253 two antibody combination.
  • IMM-BCP-01 induces a more robust antibody-dependent cellular cytotoxicity than any of the individual component antibodies when assessed in vitro using Promega’s ADCC Reporter Bioassay and S-expressing CHO-K1 target cells at a 2:1 effector:target cell ratio and manufacturer protocols.
  • the IMM-BCP-01 cocktail robustly induces multiple effector functions in a manner that is enhanced by the presence of two or more of its constituent antibodies as compared to the individual antibodies alone.
  • IMM20253 may neutralize SARS-CoV-2 through a mechanism that alters Spike protein conformation. As depicted in FIG. 2, IMM20253 binds to an epitope that is on the outside face of the RBD domain of the SARS-CoV-2 RBD. When in the closed conformation, the epitope is in close proximity to the N-terminal domain of a second Spike protein within the Spike trimer.
  • Nb nanobodies
  • Biochemical characterization the Class III Nb demonstrates that binding of the Nb to the Spike protein induces a conformational change to the post-fusion conformation. This presumably inactivates the virus’ ability to bind cells and provides a mechanism for the neutralization observed in vitro.
  • IMM20253 is unable to directly compete for ACE2 binding (FIGS. 20A-20C), but is able to neutralize both reference and alpha variant live virus as a single agent when measured as a function of virus internalization (Table 9). Together, these data suggest that IMM20253 binding to the outer face of the RBD may impart its intrinsic neutralization through induction of a conformational change in the Spike protein that prevents virus uptake into the cells without competing for ACE2 binding.
  • IMM20253 appears to be approximately 30-times more potent against the alpha strain than the delta strain. This may be a function of the internalization kinetics of the two different variants. This difference may also underlie the strong synergy observed between the IMM20184/IMM20190/IMM20253 in the context of neutralizing the alpha variant (FIGS. 7A-7C). It should be noted that like Greaney et al [Greany e al], Sun et al describe the region around the IMM20253 epitope as being of therapeutic interest, one to which antibodies are not known to exist [Greany et al] and one that is going to be difficult for antibodies to access [Sun et al].
  • IMM20190/Spike trimer complex maintains a similar hydrodynamic radius throughout the two hour incubation.
  • Binding of either IMM20253, IMM20184, or the combination of the two antibodies (IMM20253/IMM20184) induces combinatorial effects, preferably synergy, when combined with the ACE2-competitive antibody IMM20190.
  • Combinations of IMM20253, IMM20184, or IMM20253/IMM20184 induces synergy with other ACE2-competing enzymes.
  • IMM20253, IMM20184, or IMM20253/IMM20184 combines with one or more of the following antibodies to induce combinatorial, preferably synergistic, viral neutralization in vitro and promote in vivo viral clearance.
  • Examples of antibodies that combine to induce the combinatorial effect with IMM20253, IMM20184 or IMM20253/IMM20184 include, but are not limited to, sotrovimab, casirivimab, imdevimab, bamlanivimab, etesevimab, tixagevimab, cilgavimab, ADG2, ADG10, ADG20, ADG30, and CR3022.
  • IMM20253 works in combination with IMM20184, as well as in-house generated versions of REGN987 (imdevimab) and REGN933 (casirivimab) when assayed against B.1.617.2 ay2 pseudovirus.

It binds at approximately a 45 degree angle to the vertical axis of the spike as compared to the 90 degree angle adopted by IMM20184. [0236] Only a single FAb of IMM20253 is ever observed to bind to the intact trimer (FIGS. 32A-32B).

Field of the Invention [0003] The present invention relates to methods of administering antibodies used for treatment of SARS-CoV-2 infections. Background [0004] Since its emergence in Wuhan, China in late 2019 [Zhou et al. 2020], the prolonged spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus has resulted in one of the most devastating global health challenges of the last century [Nature Editorial 2020, Morens & Fauci 2020, Chakraborty & Maity 2020]. With greater than 289 million confirmed cases and over 5.43 million deaths world-wide, the virus continues to pose an extraordinary challenge to the scientific community, consequently becoming an unprecedented socio-economic disaster and burdening healthcare systems around the world. Infection with SARS-CoV-2 results in a myriad of pathologies [Berlin et al. 2020] collectively referred to as COVID-19 [3]. While a majority of individuals who become infected with the virus are capable of generating a productive anti-viral response, for many their anti-viral humoral response will not be sufficient to shield them from a potentially deadly infection. Therefore, as the global community braces for the next Spike in infection and mortality rates, the urgency to develop effective therapeutics recapitulating the productive anti-viral response to combat the swelling health crisis has never been greater. [0005] By the end of October 2020, a mere 11 months after the virus was first identified, the Clinicaltrials.gov database listed more than 3500 distinct clinical trial activities directed at patients infected with SARS-CoV-2. There is significant diversity among these efforts, from the assessment of existing drugs to the use of convalescent plasma from recovered patients, to the use of specific vaccines and antibodies directed at the viral S protein. It is not yet apparent that there will be a single approach that will prove to be uniformly effective at preventing viral infections or accelerating viral clearance in all groups of COVID-19 patients. [0006] SARS-CoV-2 genomic RNA contains a large viral replicase gene, genes encoding non-structural proteins at its 5’ end, and a region encoding four major structural and multiple accessory proteins at the 3’ end. Structural proteins include Spike or Surface glycoprotein (S), Membrane protein (M), Envelope protein (E) and Nucleocapsid protein (N) [Fehr & Perlman 2015]. The membrane surface glycoprotein S consists of two subunits, S1 and S2, that mediate viral binding to the host receptor ACE2 and fusion with the host cell membrane, respectively. The S1 subunit contains the receptor binding domain (RBD) that directly interacts with ACE2 and is a target of multiple neutralizing antibodies currently in clinical trials [Lan et al. 2020, Robbiani et al. 2020]. The vast majority of the ongoing efforts are all targeting the S protein. Both passive (therapeutic antibodies) and active (vaccine) approaches directed at S protein are expected to promote virus neutralization, that is, inhibition of viral entry into healthy cells. Unfortunately, mutations in S protein have arisen, including ones the Center for Disease Control (CDC) has identified in a series of viral variants for which there is evidence of an increase in transmissibility, increased levels of hospitalization and/or deaths, significant reduction in neutralization by antibodies generated during previous infections or vaccinations, reduced effectiveness of treatments or vaccines, or diagnostic detection failures. These virus variants are considered Variants of Concern include Alpha (U.K./B.1.1.7) variant of SARS-CoV-2, the Beta (South African/B.1.351) variant of SARS-CoV-2, the Gamma (Brazilian/P.1) variant of SARS-CoV-2, the Delta (India/B.1.617.2), B.1.617 (L452R/E484Q )), the Epsilon (California/B.1.429/427, New York/B.1.526/526.1) variant of SARS-CoV-2, the UK/Nigeria (B.1.525) variant of SARS-CoV-2, the Brazilian (P.2) variant of SARS-CoV- 2, the lambda (C.37) variant of SARS-CoV-2, or the Omicron (B.1.1.529) variant of SARS- CoV-2. Additionally, the CDC has identified Variants of Interests, which are defined as having specific genetic markers that are predicted to affect transmission, diagnostics, therapeutics, or immune escape. Data also demonstrates these variants of interest were the cause of an increased proportion of cases or outbreak, but they are of limited prevalence in the US or other countries (https://www.cdc.gov/coronavirus/2019-ncov/cases- updates/variant-surveillance/variant-info.html#Concern). [0007] Studies are described herein that elucidate the memory B cell antibody response in convalescent patients, using an approach that enables the generation of large, stable hybridoma libraries from primary human B cells. This approach was previously used to identify a panel of monoclonal antibodies from convalescent patients infected with natural polio virus (PV), oral PV-vaccinated and inactivated PV-boosted healthy subjects [Puligedda et al. 2014, Puligedda et al. 2017, Puligedda et al. 2020], and, most recently, an anti-amyloid antibody with the anti-biofilm activity [Tursi et al. 2020] from a hybridoma library generated with memory B cells from an Alzheimer’s Disease patient [Levites et al. 2015]. [0008] Hybridoma libraries were generated from the memory B cells of convalescent COVID-19 blood donors who were eligible to donate convalescent plasma based upon their high titer of IgG antibodies against the SARS-CoV-2 virus. Monoclonal antibodies derived from those libraries were selected on the basis of their selective binding to one of multiple SARS-CoV-2 proteins used as targets in both cell-based and soluble protein-based screens. Characterization of these antibodies revealed broad responses to diverse viral antigens. Fewer than half of the antibodies were directed at S protein, while the remainder were directed at other viral proteins including N and ORF-encoded proteins. Even though the antibodies were directed at highly diverse SARS-CoV-2 antigens, they were generally characterized as having variable levels of somatic hypermutation (SHM) and a diversity of VH and VL gene usage. Functional properties of anti-Spike antibodies were successfully confirmed against reference strains (e.g., USA/WA_CDC-WA1/2020), as well as multiple variants including the CDC variants of concern, in series of tests ranging from in vitro neutralization of both pseudovirus and live virus isolates to in vivo neutralization activity in a hamster model of COVID-19. Three anti-Spike antibodies were identified that when mixed together in a cocktail exhibited combinatorial effects against those variants. These studies indicate that an unbiased interrogation of COVID-19 patient B cell repertoires is an effective approach to identifying specific antiviral antibodies and antibody mixtures with the desired binding and functional properties. Antibodies identified and characterized in this manner could be recombinantly produced to yield therapeutic or prophylactic products to address the COVID-19 pandemic. The rapidity with which antibodies from convalescent patients can be identified and characterized suggests that this platform could be a useful component of a rapid response to future pandemics.

Detailed Description [0047] Methods of treating the severe acute respiratory syndrome coronavirus 2 (SARS- CoV-2) virus are described herein. In some embodiments, the methods comprise treating an immunocompromised subject. In some embodiments, the subject has a high risk for contracting SARS-CoV2. In some embodiments, the subject has a suppressed immune system. In some embodiments, the individual is being treated with an immunosuppressive agent. These antibodies may be used to neutralize SARS-CoV-2 by preventing the virus from infecting new host cells. Therefore, the inventions disclosed here also relate to pharmaceutical compositions that contain one or more antibodies of the invention, as well as relate to methods of preventing or treating a SARS-CoV-2 infection in a subject in need thereof. Accordingly, the inventions disclosed herein also relate to methods of administering antibody compositions of the invention to a subject in need thereof. [0048] In some embodiments, the antibodies, compositions, and kits provided herein are especially effective for treating and/or preventing SARS-CoV-2 due to particular novel properties. In some embodiments, provided herein are antibodies that bind to the Spike protein at multiple different locations, for example at multiple non-overlapping epitopes. This is beneficial because SARS-CoV-2 variants may have one or more mutations in the Spike protein to evade the immune system. Thus providing multiple antibodies that bind to multiple different locations in the Spike protein allows binding and neutralization of such variants. [0049] Moreover, some of the antibodies provided herein bind to an ACE2 binding site in the Spike protein, while others bind outside the ACE2 binding site. Without being bound by theory, providing multiple antibodies, some of which target the ACE2 binding site and some of which target regions outside of the ACE2 binding site may combine to provide more effective treatment for SARS-CoV-2. [0050] Accordingly, in some embodiments, provided herein is a method of treating or preventing SARS-CoV-2 comprising administering multiple antibodies that bind to non- overlapping epitopes on the Spike protein. In some embodiments, the method comprises administering an antibody that binds to an ACE2 binding site of the Spike protein and an antibody that binds to an epitope outside of the ACE2 binding site of the Spike protein. In some embodiments, the method comprises administering an antibody that neutralizes SARS- CoV-2 through an ACE2-dependent mechanism and an antibody that neutralizes SARS-CoV- 2 through an ACE2-independent mechanism. [0051] As used herein “dose” or “dosage” refers to the amount of a single agent (such as an antibody). The term “total dose” is used to refer to a total amount of multiple agents that are delivered as a combination therapy (for example, an antibody cocktail). By way of example, an antibody cocktail comprising three antibodies each delivered at a dose of 200 mg is considered to be administered at a total dose of 600 mg. The multiple agents in such a combination therapy can be administered in the same or different compositions and simultaneously or sequentially.

[0124] In certain embodiments, an effective amount of an antibody or antibody composition of the invention to prevent or treat SARS-CoV-2 infection does not result in complete protection from a SARS-CoV-2 disease but results in a lower titer or reduced number of SARS-CoV-2 viruses compared to an untreated subject. In certain embodiments, the effective amount results in a 0.5-fold, 1-fold, 2-fold, 4-fold, 6-fold, 8-fold, 10-fold, 15- fold, 20-fold, 25-fold, 50-fold, 75-fold, 100-fold, 125-fold, 150-fold, 175-fold, 200-fold, 300- fold, 400-fold, 500-fold, 750-fold, or 1,000-fold or greater reduction in titer of SARS-CoV-2 virus relative to an untreated subject. In some embodiments, the effective amount results in a reduction in titer of SARS-CoV-2 virus relative to an untreated subject of approximately 1 log or more, approximately 2 logs or more, approximately 3 logs or more, approximately 4 logs or more, approximately 5 logs or more, approximately 6 logs or more, approximately 7 logs or more, approximately 8 logs or more, approximately 9 logs or more, approximately 10 logs or more, 1 to 5 logs, 2 to 10 logs, 2 to 5 logs, or 2 to 10 logs. Benefits of a reduction in the titer, number or total burden of SARS-CoV-2 virus include, but are not limited to, less severe symptoms of the infection, fewer symptoms of the infection, reduction in the length of the disease associated with the infection, reduction in the length of viral shedding, and prevention of the onset or diminution of severity of diseases occurring secondary to SARS- CoV-2 virus infections. Antibodies [0125] Antibodies of the invention are typically monoclonal antibodies, meaning an antibody is produced by a single clonal B-lymphocyte population, a clonal hybridoma cell population, or a clonal population of cells into which the genes of a single antibody, or portions thereof, have been transfected. Monoclonal antibodies are produced by methods known to those of skill in the art, for instance by making hybrid antibody-forming cells from a fusion of myeloma cells with immune lymphocyte cells. [0126] An antibody of the invention may also be an "antigen-binding fragment". An antigen-binding fragment refers to a polypeptide fragment of an immunoglobulin or antibody that binds antigen or competes with intact antibody (i.e., with the intact antibody from which they were derived) for antigen binding (i.e., specific binding to an epitope of SARS-CoV-2). As used herein, the term "fragment" of an antibody molecule includes antigen-binding fragments of antibodies, for example, an antibody light chain variable domain (VL), an antibody heavy chain variable domain (VH), a single chain antibody (scFv), a F(ab')2 fragment, a Fab fragment, an Fd fragment, an Fv fragment, and a single domain antibody fragment (DAb). Fragments can be obtained, e.g., via chemical or enzymatic treatment of an intact or complete antibody or antibody chain or by recombinant means. Examples of immunoglobulin variants that are considered antibodies according to the invention include single-domain antibodies (such as VH domain antibodies), Fab fragments, Fab' fragments, F(ab)'2 fragments, single chain Fv proteins ("scFv"), and disulfide stabilized Fv proteins ("dsFv"). A VH single-domain antibody is an immunoglobulin fragment consisting of a heavy chain variable domain. An Fab fragment contains a monovalent antigen-binding immunoglobulin fragment, which can be produced by digestion of whole antibody with the enzyme papain to yield an intact light chain and a portion of one heavy chain. Similarly, an Fab' fragment also contains a monovalent antigen-binding immunoglobulin fragment, which can be produced by digestion of whole antibody with the enzyme pepsin, followed by reduction, to yield an intact light chain and a portion of the heavy chain. Two Fab' fragments are obtained per immunoglobulin molecule. A (Fab')2 fragment is a dimer of two Fab' fragments, that can be obtained by treating whole antibody with the enzyme pepsin without subsequent reduction, so Fab' monomers remain held together by two disulfide bonds. An Fv fragment is a genetically engineered fragment containing the variable region of the light chain and the variable region of the heavy chain expressed as two chains. A single chain ("sc") antibody, such as scFv fragment, is a genetically engineered molecule containing the VL region of a light chain, the VH region of a heavy chain, linked by a suitable polypeptide linker as a genetically fused single chain molecule. A dimer of a single chain antibody, such as a scFV2 antibody, is a dimer of a scFV, and may also be known as a "miniantibody". A dsFvs variant also contains a VL region of an immunoglobulin and a VH region, but the chains have been mutated to introduce a disulfide bond to stabilize the association of the chains. [0127] One of skill in the art will realize that conservative variants of the antibodies can be produced. Such conservative variants employed in antibody fragments, such as dsFv fragments or in scFv fragments, will retain critical amino acid residues necessary for correct folding and stabilizing between the VH and the VL regions, and will retain the charge characteristics of the residues in order to preserve the low pI and low toxicity of the molecules. [0128] An antibody of the invention is typically a "human" antibody, which may also be referred to as a "fully human" antibody. An antibody which possess a human framework regions and CDRs from a human immunoglobulin is generally be considered to be a human or humanized antibody. For example, a human or humanized antibody may contain the framework and the CDRs of an antibody from the same originating human heavy chain, or human light chain amino acid sequence, or both. Alternatively, the framework regions may originate from one human antibody, and be engineered to include CDRs from a different human antibody. [0129] An antibody according to the invention may also comprise a "tagged" immunoglobulin CH3 domain to facilitate detection of the biologic against a background of endogenous antibodies. More particularly, a tagged CH3 domain is a heterogeneous antibody epitope that has been incorporated into one or more of the AB, EF, or CD structural loops of a human IgG-derived CH3 domain. For example a CH3 tag may be incorporated into the structural context of an IgG1 subclass antibody, other human IgG subclasses, including IgG2, IgG3, and IgG4. Epitope-tagged CH3 domains, also referred to as "CH3 scaffolds" can be incorporated into any antibody of the invention having a heavy chain constant region, generally in the form of an immunoglobulin Fc portion. Examples of CH3 scaffold tags, and methods for incorporating them into antibodies are disclosed in International Patent Application No. PCT/US2019/032780. Antibodies used to detect epitope tagged CH3 scaffolds, and antibodies of the invention, that comprise epitope tagged CH3 scaffolds, are generally referred to herein as "detector antibodies". [0130] Some antibodies of the invention may be described as an "isolated" antibody or "isolated" antigen-binding fragment thereof. An isolated antibody or antigen-binding fragment thereof has been substantially separated or purified away from other biological components environment, such as a cell, proteins and organelles. Ordinarily, an isolated antibody or antigen-binding fragment thereof is prepared by a process involving at least one purification step, although the term "isolated" is not intended to refer to a complete absence of such biological molecules or to an absence of water, buffers, or salts or to components of a pharmaceutical formulation that includes an antibody or antigen-binding fragment of the invention. [0131] In some embodiments of the invention, antibody or antigen-binding fragment thereof is specific for the Spike protein (S) of SARS-CoV-2. Thus, an antibody or antigen- binding fragment thereof may, in one embodiment, bind the S1 subunit of the Spike protein, while in another embodiment, an antibody or antigen-binding fragment thereof binds the S2 subunit. Moreover, some antibodies or antigen-binding fragments thereof bind to the receptor-binding domain (RBD) of the S protein, while other antibodies of the invention bind to non-RBD epitopes of the S protein. RBD-binding antibodies or antigen-binding fragments thereof of the invention may, in certain embodiments, bind a soluble form of the RBD of the S protein. Some antibodies or antigen-binding fragments of the invention bind to sites on the RBD that are resistant to mutational drift. For example, in some embodiments, an antibody or antigen-binding fragment thereof binds the RBD at, or in close proximity of such a site described by Greaney t al. (2021) as the “the E465 patch”. [0132] Indeed, among the antibodies of the invention that bind the Spike protein, there are some that bind to highly-conserved epitopes. Accordingly, binding of an antibody or antigen-binding fragment of the invention to a highly-conserved site of the SARS-CoV-2 Spike protein is not affected by point mutations in the Spike protein associated with variants of SARS-Cov-2, Alpha (U.K./B.1.1.7) variant of SARS-CoV-2, the Beta (South African/B.1.351) variant of SARS-CoV-2, the Gamma (Brazilian/P.1) variant of SARS-CoV- 2, the Delta (India/B.1.617.2), B.1.617 (L452R/E484Q )), the Epsilon (California/B.1.429/427, New York/B.1.526/526.1) variant of SARS-CoV-2, the UK/Nigeria (B.1.525) variant of SARS-CoV-2, the Brazilian (P.2) variant of SARS-CoV-2, the lambda (C.37) variant of SARS-CoV-2, or the Omicron (B.1.1.529) variant of SARS-CoV-2. [0133] In certain embodiments of the invention, an isolated antibody or antigen-binding fragment thereof contains a heavy chain variable region (HCVR) and a light chain variable region (LCVR) that is described in Table 1. In some embodiments, provided herein is an antibody comprising a HCDR1, a HCDR2, a HCDR3, a LCDR1, a LCDR2, and a LCDR3 of a heavy chain variable region (HCVR) and a light chain variable region (LCVR) that is described in Table 1. In some embodiments, provided herein is an antibody comprising a HCDR1, a HCDR2, a HCDR3, a LCDR1, a LCDR2, and a LCDR3 set forth in Table 1. In some embodiments, the CDRs are determined using Kabat, Chothia, or contact systems. In some embodiments, the CDRs are determined using the system described in North et al.

A nonlimiting list of examples of antibodies or antigen-binding fragments of the invention which bind equivalently to the SARS-CoV-2 reference isolate, USA/WA_CDC-WA1/2020, and each of the aforementioned variant isolates, include: An antibody with a HCVR based on the amino acid sequence set forth in SEQ ID NO: 1 or fragment thereof, and a LCVR based on the amino acid sequence set forth in SEQ ID NO: 2 or fragment thereof; An antibody with a HCVR based on the amino acid sequence set forth in SEQ ID NO: 3 or fragment thereof, and a LCVR based on the amino acid sequence set forth in SEQ ID NO: 4 or fragment thereof; An antibody with a HCVR based on the amino acid sequence set forth in SEQ ID NO: 5 or fragment thereof, and a LCVR based on the amino acid sequence set forth in SEQ ID NO: 6 or fragment thereof; and An antibody with a HCVR based on the amino acid sequence set forth in SEQ ID NO: 19 or fragment thereof, and a LCVR based on the amino acid sequence set forth in SEQ ID NO: 20 or fragment thereof. [0139] The foregoing antibodies of the invention neutralize SARS-CoV-2 and SARS- CoV-2 variants, including variants Alpha (U.K./B.1.1.7), Beta (South African/B.1.351), Gamma (Brazil/P.1), Delta (India/B.1.617.2), B.1.617 (L452R/E484Q) and Epsilon (California/B.1.429/427), either alone, or in combination. In some embodiments, the antibodies neutralize the Alpha (U.K./B.1.1.7) variant of SARS-CoV-2, the Beta (South African/B.1.351) variant of SARS-CoV-2, the Gamma (Brazilian/P.1) variant of SARS-CoV- 2, the Delta (India/B.1.617.2), B.1.617 (L452R/E484Q )), the Epsilon (California/B.1.429/427, New York/B.1.526/526.1) variant of SARS-CoV-2, the UK/Nigeria (B.1.525) variant of SARS-CoV-2, the Brazilian (P.2) variant of SARS-CoV-2, the lambda (C.37) variant of SARS-CoV-2, or the Omicron (B.1.1.529) variant of SARS-CoV-2. More particularly, certain antibodies of the invention bind the SARS-CoV-2 RBD at epitopes, which contain residues that are conserved among variants. In some embodiments, binding to such conserved residues prevents viral escape. In some embodiments, binding to such conserved residues allows binding across variants. Accordingly, a RBD amino acid substitution at a non-conserved or poorly-conserved residue position will have limited or no impact on binding of an antibody of the invention. Such non conserved or poorly-conserved substitutions in the RBD are commonly associated with SARS-CoV-2 variants. Thus, an RBD epitope of some antibodies of the invention may contain at least 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 or more residues at RBD positions 356 (K), 370 (N), 372 (A), 374 (F), 378 (K), 384 (P), 417 (K), 420 (D), 455 (L), 456 (F), 460 (N), 466 (R), 473 (Y), 487 (N), 489 (Y), 501 (N), and 505 (Y). For example, an antibody of the invention may bind an RBD epitope in which the binding energy is relatively higher at residues at 417 (K), 420 (D), 455 (L), 456 (F), 460 (N), 473 (Y), 487 (N), 489 (Y), 501 (N), and 505 (Y). Likewise, another antibody of the invention may bind an RBD epitope in which the binding energy is relatively higher at residues at 370 (N), 372 (A), 374 (F), 378 (K), 384 (P). And yet another antibody of the invention may bind an RBD epitope in which the binding energy is relatively higher at residues at 356 (K) and 466 (R). In some embodiments, the antibody contacts one or more residues at RBD positions 356 (K), 370 (N), 372 (A), 374 (F), 378 (K), 384 (P), 417 (K), 420 (D), 455 (L), 456 (F), 460 (N), 466 (R), 473 (Y), 487 (N), 489 (Y), 501 (N), and 505 (Y). In some embodiments, the antibody contacts one or more of 417 (K), 420 (D), 455 (L), 456 (F), 460 (N), 473 (Y), 487 (N), 489 (Y), 501 (N), and 505 (Y). In some embodiments, the antibody contacts residues at 370 (N), 372 (A), 374 (F), 378 (K), 384 (P). In some embodiments, the epitope is identified using alanine scanning. [0140] In some embodiments, the antibody binds the SARS-CoV-2 RBD at epitopes, which contain residues that are not conserved. [0141] In certain embodiments of the invention, for example, a composition (i.e., a mixture) of two or more of: An antibody with a HCVR based on the amino acid sequence set forth in SEQ ID NO: 1 or fragment thereof, and a LCVR based on the amino acid sequence set forth in SEQ ID NO: 2 or fragment thereof; An antibody with a HCVR based on the amino acid sequence set forth in SEQ ID NO: 3 or fragment thereof, and a LCVR based on the amino acid sequence set forth in SEQ ID NO: 4 or fragment thereof; An antibody with a HCVR based on the amino acid sequence set forth in SEQ ID NO: 5 or fragment thereof, and a LCVR based on the amino acid sequence set forth in SEQ ID NO: 6 or fragment thereof; An antibody with a HCVR based on the amino acid sequence set forth in SEQ ID NO: 19 or fragment thereof, and a LCVR based on the amino acid sequence set forth in SEQ ID NO: 20 or fragment thereof; and An antibody with a HCVR based on the amino acid sequence set forth in SEQ ID NO: 21 or fragment thereof, and a LCVR based on the amino acid sequence set forth in SEQ ID NO: 22 or fragment thereof, additively or synergistically neutralizes SARS-CoV-2, or a variant thereof, such as the Alpha (U.K./B.1.1.7), Beta (South African/B.1.351), Gamma (Brazil/P.1), Delta (India/B.1.617.2), B.1.617 (L452R/E484Q) and Epsilon (California/B.1.429/427). In some embodiments, the antibodies neutralize the Omicron variant. In some embodiments, the antibodies neutralize Alpha (U.K./B.1.1.7) variant of SARS-CoV-2, the Beta (South African/B.1.351) variant of SARS-CoV-2, the Gamma (Brazilian/P.1) variant of SARS-CoV-2, the Delta (India/B.1.617.2), B.1.617 (L452R/E484Q )), the Epsilon (California/B.1.429/427, New York/B.1.526/526.1) variant of SARS-CoV-2, the UK/Nigeria (B.1.525) variant of SARS-CoV-2, the Brazilian (P.2) variant of SARS-CoV-2, the lambda (C.37) variant of SARS-CoV-2, or the Omicron (B.1.1.529) variant of SARS-CoV-2. [0142] In some embodiments, an antibody of the invention alters the conformation of Spike protein upon binding of the antibody to the Spike protein. More particularly, in certain embodiments, an antibody of the invention binds a Spike protein epitope located on the outside face of the RBD domain of the SARS-CoV-2 RBD. In such embodiments, the epitope may be in close proximity to the N-terminal domain of a second Spike protein within the Spike trimer, and binding of the antibody inactivates the virus’ ability to bind cells. Consequently, certain antibodies of the invention neutralize SARS-CoV-2 by the foregoing mechanism. More specifically, binding of such antibodies to the outer face of the RBD imparts its intrinsic neutralization through induction of a conformational change in the Spike protein that prevents virus uptake into the cells without competing for ACE2 binding. An example of an embodiment of the invention that alters conformation of the Spike protein upon binding is an antibody with a heavy chain variable region (HCVR) or fragment thereof and/or a light chain variable region (LCVR) or a fragment thereof derived from an antibody described herein as IMM20253, which contains HCVR and LCVR with amino acid sequences of SEQ ID NOS. 5 and 6, respectively. [0143] In certain embodiments, an antibody of the invention that alters the conformation of Spike protein upon binding of the antibody to the Spike protein as part of its intrinsic neutralization activity, acts additively, and more preferentially synergistically, with other antibodies that compete for ACE2 binding as part of their intrinsic neutralization mechanism. An example of an embodiment of the invention that alters conformation of the Spike protein upon binding and acts additively, and more preferentially synergistically, with antibodies that block ACE2 binding, is an antibody with a heavy chain variable region (HCVR) or fragment thereof and/or a light chain variable region (LCVR) or a fragment thereof derived from an antibody described herein as IMM20253, which contains HCVR and LCVR with amino acid sequences of SEQ ID NOS. 5 and 6, respectively. [0144] As described above, an isolated antibody or antigen-binding fragment thereof of the invention may contain a CH3 scaffold "epitope tag", comprising at least one modification of the wild-type amino acid sequence of the CH3 domain derived from an immunoglobulin Fc region. Accordingly, any of the aforementioned antibodies may have been engineered to contain a CH3 scaffold. The CH3 scaffold of such an isolated antibody or antigen-binding fragment thereof may possess at least one modification of the wild-type sequence occurs within the AB, EF, or CD loops of the CH3 scaffold, including an amino acid substitution, deletion or insertion, for example. In certain embodiments, the epitope tag amino acid sequence contains a sequence derived from SIRPα or Sip. Alternatively, he epitope tag amino acid sequence contains a sequence derived from a constant light chain of an antibody. More particularly, the antibody epitope amino acid sequence of an isolated antibody or antigen-binding fragment thereof that contains a CH3 scaffold with an amino acid sequence set forth in SEQ ID Nos. 3-30, SEQ ID Nos. 33-57, or SEQ ID Nos. 60-67 of International Patent Application No. PCT/US2019/032780.

Evaluation of the breadth of patients’ humoral responses against SARS-CoV-2. The overall spectrum of the productive antibody response to SARS-CoV-2 was examined using an automated, high-throughput hybridoma library generation and screening platform [Puligedda et al. 2014] after isolating memory B cells acquired from blood samples of COVID-19 convalescent patients who demonstrated a high antibody titer to N and/or S proteins. [0180] Collection of patient samples. Blood samples were drawn from convalescing COVID-19 patient volunteers deemed eligible for donating convalescent plasma as set forth in the U.S. Food and Drug Administration (FDA)’s Recommendations [FDA 2020]. Patients displayed no PCR-detectable viremia and maximal IgG (2880) titer of class switched, virus- specific antibodies. [0181] Generation of hybridoma libraries. Hybridomas were generated from the memory B cells isolated from the donors by following protocols for isolating and expanding primary B cells as well as electrofusion methods described in U.S. patents [Dessain & Weinberg 2002, Dessain & Adekar 2009]. Hybridomas stably expressing human mAbs were generated by electrofusion of expanded B-cells to the B5-6T myeloma cell line, which expresses an ectopic human telomerase gene that stabilizes human chromosomes in the hybrid cells created. Fused hybridomas were plated into 96-well plates in growth medium with HAT selection of stable hybridomas for 7 days. After 7 days, growth media were switched to media with HT for stable selected hybridoma growth. Hybridomas were cultured in a 37°C incubator for 14-21 days during which time they were imaged for monoclonality and monitored for isotype-and sub-class-specific Ig secretion. Supernatants from monoclonal wells expressing measurable levels of Ig were cherry-picked and submitted for target-based screening. [0182] Screening Assays For Antiviral Antibodies. The naturally occurring human antibodies (IgM, IgG, and IgA isotypes) secreted by those hybridomas were screened for reactivity against a panel of SARS-CoV-2 proteins. Antibody screening assays were developed for three SARS-CoV-2 structural proteins (S, N, M) and a panel of accessory ORF proteins of SARS-CoV-2. In addition to the reference Spike (S) protein corresponding to that found on the USA/WA_CDC-WA1/2020 virus, counterscreening was carried out on Spike proteins, or Spike protein domains, corresponding to the Spike proteins present on the surface of viral variants. The breadth of variants tested are described in Table 2. Table 2. SARS-CoV-2 Spike Screening Proteins SARS-CoV-2 Viral Tar et Assa S stem Variants Tested 453F, . n 4K, partial Y144, 69/70, R,

[0183] The screening assays included a rapid and sensitive homogeneous time resolved fluorescence (hTRF) assay that used soluble recombinant viral proteins, as well as a selective, cell-based flow cytometry assay that allowed probing of antibodies to transiently transfected viral antigens expressed within the context of human cells. Viral protein expression in the cell-based assay was additionally confirmed by Western blot. For cell-based assays, using commercially available controls, the localization of the C-terminus truncated Spike protein (SΔ19aa) was confirmed to be on the surface of the transfected cells. Commercially available antibodies specific for SARS-CoV-2 targets, and more specifically the Spike protein, demonstrated selective and saturable binding in both assays. Screening led to the isolation of antibodies specific for eight different viral proteins (FIG. 1). [0184] HTRF Screening Assays. A homogeneous time-resolved fluorescence (hTRF) assay [Degorce et al. 2009] comprised of terbium labeled anti-human IgG (H+L) (Cisbio, custom label) donor and AF488-labeled anti-HIS (Cell Signaling, Cat # 14930S) acceptor antibodies was used to screen patient-derived antibodies for their binding to recombinantly produced SARS-CoV-2 antigens, and more specifically to the SARS-CoV-2 Spike protein. The assay, adapted for high-throughput screening, was optimized so that a number of recombinant, HIS-tagged SARS-CoV-2 target proteins could be substituted interchangeably. This recombinant target panel consisted of a full-length S (FL, trimer-stabilized, LakePharma) and two truncated S protein domains, S1 (GenScript, Cat # Z03485-1) and RBD (aa 319-591, LakePharma). Commercially available antibodies specific for the individual structural viral proteins, SARS-CoV/SARS-CoV-2 Spike S1 (RBD) chimeric mAb (Sino Biological, Cat # 40150-D001), SARS CoV-2 Nucleocapsid human chimeric mAb (GenScript, Cat # A02039-100 served as controls. Assay background was determined by averaging the signal of wells containing only the donor and acceptor cocktail. Hybridoma supernatants exhibiting signals greater than 2-fold over background were reported as positive HITs and are submitted for Ig sequence analysis. [0185] Flow cytometry-based cellular screens for antiviral antibodies. SARS-CoV-2 antigen sequences were cloned into pcDNA3.4 plasmids and transfected into 293F cells utilizing the Expi293 Expression System (Life Technologies, Inc.) per manufacturer’s instructions. Cells transiently expressing SARS-CoV-2 S (SΔ19aa) were used for screening. Optimal protein expression was achieved three days post-transfection for S proteins. [0186] For the cell-surface binding assays cells were incubated with LIVE/DEAD Cell Stain (Life Technologies, Inc.) per the manufacturer’s instructions. Live cells expressing SΔ19aa were suspended in QSol Buffer (IntelliCyte Corporation) to which a cocktail of Fc-specific secondary antibodies was added: AF647 goat anti-human IgG (Jackson ImmunoResearch, Inc.), AF488 goat anti-human IgA (Jackson ImmunoResearch, Inc.) and BV650 mouse anti-human IgM (BioLegend, Inc.). [0187] For each assay, the cell suspensions were dispensed into 384-well plates, followed by the addition of hybridoma supernatant at a 1:10 final dilution. The reaction was allowed to incubate for 90 minutes at room temperature. Cells for each assay were fixed with a final concentration of 1% paraformaldehyde and analyzed with IntelliCyte iQue Screener (IntelliCyte Corporation). Positive binding gates for detection of each secondary antibody were established using cells plus secondary antibody cocktail as a negative control. Binding of hybridoma supernatant antibodies to specific SARS-CoV-2 proteins, and more specifically the SΔ19a, were quantified as percent positive relative to the secondary only control. To calculate percent positive, live events that shifted into detection channels were divided by the total live events. [0188] Example 2. Immunoglobulin gene usage in convalescent COVID-19 patients. Ig gene usage in memory B cells of six COVID-19 patients was evaluated using an NGS analysis of identified and sequenced 134 hybridoma hits. RNA isolation and Next Generation Sequencing (NGS). Hybridoma RNA was isolated using Invitrogen RNAqueous-96 Total RNA Isolation Kit (Cat. #AM1920). Isolated RNA samples were submitted to iRepertoire (Huntsville, AL) for NGS. Hybridoma-derived RNA samples were sequenced using the Illumina MiSeq system at iRepertoire (Huntsville, AL). Sequencing runs were performed using the MiSeq Nano Kit V2 following bead-based cleanup of RNA. Immunoglobulin sequences containing CDR1, 2 and 3 and framework regions were amplified using IgG and IgA-specific mixes for IgH, and kappa and lambda- specific primers for IgL. IgM-expressing hybridoma samples, from which IgG or IgA heavy chains were not amplified using this approach, were sequenced using the iRepertoire iPair system. Final sequences were exported using iPair software. [0189] Immunoglobulin sequences were analyzed for predicted CDR sequences, % identity to appropriate germlines, isotype of the constant regions and read counts. Sequence pairing was performed based on the read count information. In the event more than one LC:HC pair was discovered in a single well, each LC:HC combination was analyzed as a separate antibody. In all cases, sequencing method resulted in 5’ truncation in the VH and VL regions, the germline sequence for the closest related V gene was used to generate a full- length version of each gene. The gene sequences were codon optimized to create expression constructs for recombinant production and testing of antibodies. Final sequences were translated and analyzed for potential stop codons and frame shifts. [0190] Example 3. Recombinant production of antibodies. Heavy and light chain pairs from 103 clones, from which productive immunoglobulin RNA sequences were determined, were expressed as recombinant antibodies. [0191] Production of paired light and heavy chains. Variable domains yielding productive uninterrupted protein sequences were analyzed for number of reads and the degree of somatic hypermutations (SHM) in comparison to the closest immunoglobulin germline. Hybridoma hit sequences with at least one chain that had more than 2% of SHM were advanced to HC/LC pairing and the recombinant production of antibodies. Immunoglobulin expression fragments were cloned into the pcDNA3.4-based vectors and expressed in 293F cells. Affinity and binding pattern of recombinant antibodies were compared to the original antibody-containing hybridoma supernatants in BLI, HTRF and cell-based assay. Antibody- containing supernatants or purified antibodies were advanced to downstream assays. If multiple heavy or light chain sequences were detected within one well, their CDRs were aligned and compared for potential PCR errors. In cases where multiple sequences within a well were different, i.e., originated from separate clones, all potential combinations of light and heavy chains were recombinantly produced and tested in downstream assays. Wells that yielded a single HC/LC pair were advanced to recombinant expression and downstream assays. 5’ fragments of the constant regions were sequenced to identify the isotype of the antibody and compared to the experimentally identified isotype of hybridoma supernatants. The resulting isotype of the heavy or light chain was assigned based on two or more positive readings from experimental (ex. ELISA and FACS) assays and sequencing. [0192] A combined analysis of Ig isotype and their level of SHM of virus-specific antibodies revealed several key properties of the productive antiviral response. First, among all “mutated” immunoglobulins that had more than 2% of their nucleotide sequence deviated from the closest germline, there was an unusually high (26.4%) proportion of mutated IgMs, having a mean SHM rate of 5.73%. The functional basis of this phenomenon is not known, but one could speculate that these IgMs came from non-switched memory B cells that had undergone affinity maturation. Second, a subset of such somatically hypermutated IgMs recognized full-length Spike, but not the soluble RBD or S1 subunit of Spike protein. And third, while the predominant isotype among class-switched antibodies was, as expected, IgG it was possible to capture a panel of fairly mutated virus-specific IgAs. It is plausible that these antibodies play a major role in mucosal neutralization of the incoming virus and may be of particular use for prophylaxis of viral infection and for vaccine design. [0193] Example 4. Identified anti-Spike antibodies from convalescent COVID-19 patients exhibit potent binding to Spike proteins mimicking a range of different viral variants. Purified recombinant antibodies were assessed, in the HTRF assay described above, using either soluble RBD or S1 domains containing mutations found in naturally occurring viral variants, as well as mutations predicted to decrease binding of neutralizing antibodies. Table 3 depicts the binding of identified anti-Spike antibodies, expressed as fold-binding over background. As anticipated, binding of some antibodies, such as PR201_00151 and PR194_00232, are negatively affected by specific mutations within the Spike domain (e.g. K417N). In contrast, binding by antibodies like PR199_00255, PR193_00018, and PR200_00622 are unaffected by the range of mutations analyzed, including variants containing single point mutations, as well as multiple point mutations that mimic the naturally occurring Spike proteins found on the B.1.1.7 and B.1.351 virus isolates. A subset of antibodies, such as PR199_00255 and PR200_00622, also bind to Spike protein found on SARS-CoV-1, suggesting that they bind to a highly conserved epitope. [0194] Binding of the antibodies PR913_00018, PR194_00232, and PR200_00622 were further characterized in the HTRF assay to determine EC50 of binding to a wide range of single and multi-point mutations, including to the B.1.1.7, B.1.429, P.1, and B.1.351 variants. Each of the antibodies bound to the Wuhan/Washington reference Spike RBD protein with EC50s in the HTRF assay of between 45 – 68 pM. Mutations that mapped to the ACE2 binding site on the RBD appear to disrupt the binding affinity of PR199_00232, whereas no mutation, or combination of mutations, tested disrupted the ability of either PR193_00018 or PR200_00622 to bind to the RBD. The ability of these two antibodies to bind to the wide range of variants suggests that their epitopes are maintained even in the face of the viral drift that has occurred to date. [0195] The impact of mutational drift on the binding of each of PR193_0018, PR194_00232, and PR200_00622 antibodies was evaluated using a series of Spike proteins containing either single point mutations or complex point mutations that recapitulate the spectrum of mutations in naturally occurring variants that have emerged across the globe. PR194_00232 is the most sensitive of the three antibodies to mutational drift within the Spike protein. Mutations, such as K417N and N501Y, mutations known to exist in naturally occurring variants, and consistent with the alanine scanning data, significantly decrease the ability of PR194_00232 to bind the Spike protein. Whereas other naturally occurring mutations, such as L452R, E484Q, or D614G do not impact binding relative to binding to the Washington reference Spike protein. In contrast, binding of PR193_0018 and PR200_00622 are not significantly impacted by any of the single point mutations tested. In fact, binding by PR193_0018 and PR200_00622 to specific variant Spike proteins (e.g., E484K and E484Q) appears to be modestly enhanced over the reference Spike. Similar observations were made when binding of PR193_0018, PR194_00232, and PR200_00622 was tested against RBD domain proteins containing the full complement of mutations known to exist in four different variants. Of particular interest is the binding to RBDs corresponding to the South African (B.1.351) and U.K. (B.1.1.7) variants. As predicted by the K417N and N501Y single point mutation data, binding of PR194_00232 to both the U.K. and S.A. variants is weaker than observed against the reference strain Spike protein.

Identified anti-Spike antibodies bind to non-overlapping epitopes within the RBD of SARS-Co-V-2 Spike. Purified recombinant forms of the PR193_00018, PR194_00232, and PR200_00622, failed to compete with each other for binding to the SARS-CoV-2 RBD when assessed via biolayer interferometry on an Octet QKe instrument. These data suggested the three antibodies bind to non-overlapping epitopes on the SARS- CoV-2 RBD. Alanine scanning of the RBD was performed to identify residues critical for binding of each of the antibodies. Consistent with each of the antibodies binding to non- overlapping epitopes, non-overlapping sets of residues were identified as being critical for binding of the antibodies (Table 5). Those residues map to unique regions of three dimensional structure of the RBD, consistent with the ability of the antibodies to fail to compete with each other for binding (FIG. 2) Table 5.

Mean binding reactivities (and ranges) are listed for all identified critical residues. Critical residues for Ab binding (boxed) were residues whose mutations were negative for binding to test Abs , but positive for binding to control Ab [0197] Example 6. Identified anti-Spike antibodies neutralize SARS-CoV-2 pseudovirus. The functional consequence of antibodies binding to Spike was assessed in assays using pseudotyped replication-incompetent lentivirus which were used to infect HEK293 cells overexpressing Angiotensin converting enzyme 2 (ACE2). Spike-expressing pseudovirus was generated with System Bioscience’s pPACK-SPIKE packaging system (System Biosciences, Cat #CVD19-500A-1) as per manufacturer’s protocol. Briefly, 8 x 106293TN Producer cells (System Biosciences, LV900A-1) were plated in T150 flasks overnight. Plasmids encoding lentiviral packaging proteins and Spike were added 1 mL of plain DMEM for each T150 being transfected. 55 mL of PureFection reagent (System Biosciences; Cat #LV750A-1) was added to each 1 mL tube, vortexed for 10 seconds, and incubated at room temperature for 15 minutes. The plasmid and PureFection mixture were added to a T150 flask containing 293TN cells and placed in a 37°C incubator containing 5% CO2 for 48 hours. Pseudovirus-containing supernatants were harvested at 48 hours and passed through a 0.45 micron PVDF filter to remove cellular debris. 5x PEG-it Virus Precipitation Solution (System Biosciences, Cat #LV810A-1) was added to supernatants and incubated 4°C overnight. Pseudovirus-containing supernatants with 1x PEG-it Virus Precipitation Solution were then spun at 1500 x g for 30 minutes. Pseudovirus-containing pellets were resuspended in plain DMEM to achieve at 10x concentration and frozen at -80°C in single use aliquots. [0198] Pseudovirus infection and neutralization assays were performed by using standard methods. Pseudoviruses were produced with the pPACK-SPIKE packaging kit, 104 ACE2- 293T cells were plated in the inner 60 wells of a white opaque 96 well flat bottom plate (Corning; Cat #3917) in 100 µL of ACE2-293T media overnight in a 37°C incubator containing 5% CO2. To determine infectivity of each lot of pseudovirus, pseudovirus- containing supernatants were thawed from -80°C and two-fold dilutions were performed. 100 mL of pseudovirus at various dilutions was added to ACE2-293T cells. To test neutralization activity of antibodies, indicated antibody concentrations were pre-incubated with pseudovirus for 1 hour in a 37°C incubator containing 5% CO2. Then, 100 µL of antibody/pseudovirus mixture was added to ACE2-293T cells. After 72 hours, cells and media were equilibrated to room temperature for 20 minutes. 100 mL of media was removed and replaced with 100 µL of Bright-Glo Luciferase Assay Reagent (Promega, Cat #E2620). Luminescence was measured on the EnSpire Plate Reader (PerkinElmer). [0199] Initial testing with pseudovirus was performed using antibody-containing supernatants, 3-4 log dilutions of 26 unique anti-Spike antibodies were tested for their ability to block infection in comparison to an anti-RSV negative control and a commercially available anti-Spike positive control. [0200] Neutralization activity of a subset of antibodies (FIGS. 3A-3D) was confirmed using SARS-CoV-2 luciferase reporter virus particles (RVP’s) (Integral Molecular) based on the manufacturer’s instructions. In brief, RVP’s were thawed for 2-3 minutes in a 37°C water bath. The recommended amount of RVP’s was added to the inner wells of a white opaque 96 well plate (Corning; Cat #3917) or 384 well plate (Greiner Bio-One; Cat #781080). Media containing the indicated amount of antibody was added to each well, resulting in a final volume of 100 mL per well (96 well plate) or 25 mL per well (384 well plate). The antibody/RVP mixture was pre-incubated for 1 hour in a 37°C incubator containing 5% CO2. ACE2-293T target cells were added to each well (2 x 104 cells in 100 mL for a 96 well plate or 0.9 x 104 cells for a 384 well plate) and incubated for 72 hours. Media was removed from all wells, equal volumes of PBS and Renilla-Glo Luciferase Assay Reagent (Promega; Cat #E2720) were added to each well (60 mL total for a 96 well plate or 30 mL total for a 384 well plate). After 10 minutes, luminescence was measured on the EnSpire Plate Reader (PerkinElmer). Percent neutralization was calculated with the following equation: [(RLU of Virus + cells) – (RLU of Experimental Sample)] / [(RLU of Virus + cells) – (RLU of cells only)]. [0201] The PR194_00232 antibody that exhibited potent neutralization against pseudovirus expressing both the reference (SARS-CoV-2/human/USA/WA_CDC- WA1/2020) and D614G (SARS-CoV-2/human/Germany/BavPat 1/2020) were also assessed in neutralization assays using live virus of each of the isolates (FIGSs 4A and 4B). [0202] Full dose response of purified antibodies confirmed strong neutralizing activity by antibodies such as PR194_00232. The D614G variant is a widespread mutation [Plante et al. 2020] found in a number of different isolates. Antibodies such as PR194_00232, that bound to the soluble protein and neutralized pseudovirus expressing the D614G Spike, were also able to neutralize the live virus with comparable IC50 values (FIG. 4B). [0203] Pseudovirus particles expressing Spike proteins that mimic the U.K. (B.1.1.7) and South African (B.1.351) isolates are neutralized by antibodies which retain binding to the mutated Spikes (Tables 3 &4). This is exemplified by the antibodies PR193_00018 and PR200_00622 (FIGS. 5A-5C). In contrast, antibodies that lose binding affinity for the mutated Spikes have a decreased neutralization potency; PR193_00232 retains neutralization activity against the UK variant pseudovirus but is unable to effectively neutralize the S. African pseudovirus. [0204] Example 7. A cocktail of three anti-SARS-CoV-2 anti-Spike antibodies elicit combinatorial effects. With the objective of producing an antibody composition that is able to neutralize both current, and future, variants, including, but not limited to, CDC Variants of Concern/Interest (alpha/B.1.1.7; beta/B.1.351; gamma/P.1; delta/B.1.617.2; epsilon/B.1.429/427), antibodies selective for non-overlapping epitopes on the SARS-CoV-2 Spike protein were assessed in pair-wise, and three-way combinations to identify additive, or preferably synergistic, neutralization. [0205] More specifically, the antibodies PR194_00232 (IMM20190), PR193_00018 (IMM20184), and PR200_00622 (IMM20253) were assessed in combinations to evaluate the combinatorial impact on neutralization of pseudovirus expressing a range of different variations of the Spike protein (FIGS. 6A-6C). IC50 values for the triple combination and double combination comprising IMM20184 and IMM20253 were determined using RVPs, as described above. [0206] As depicted in FIGS. 6AA-6C the triple combination of antibodies neutralized pseudoviruses corresponding to the USA/WA_CDC-WA1/2020 (reference sequence) and the CDC variants of concern (alpha/U.K./B.1.1.7, beta/South African/B.1.351, gamma/Brazil/P.1 and epsilon/California/B.1.429/427). In these pseudovirus assays, the IC50s for neutralization of the reference and California variants were not determined due to the potency exhibited against those variants; concentrations sufficiently low enough to obtain below 50% neutralization were not tested. Neutralization of the U.K., Brazilian, and South African were achieved with IC50s of 0.7 nM, 31 nM, and 23 nM, respectively, in these assays. The impact of IMM20190 on neutralization of the reference, CA, and UK variants can be observed by comparing the IC50s achieved with the double combination of IMM20184/IMM20253 against the same pseudoviruses. In the absence of IMM20190, the reference California and U.K. variant pseudoviruses are neutralized with higher IC50s, corresponding to 37 nM, 15 nM, and 25 nM respectively. In the case of the S. African and Brazilian, the lack of IMM20190 does not dramatically alter the IC50s, consistent with IMM20184/IMM20253 providing the majority of the neutralization activity. [0207] To determine combinatorial impact of the antibodies pseudovirus neutralization experiments were set up as described above, except that for combinations of two antibodies, one test article was titrated in the background of each concentration in a serial dilution of the other test article. Single antibody titrations were included as controls. For combinations of three antibodies, one test article was titrated in the background of each concentration in a serial dilution of a 1:1 mixture of the other two test articles. To evaluate antibody synergy in the combinations, the observed combination response matrix of pseudovirus neutralization was used as input for the online SynergyFinder platform (4), where quadruplicate data points were input separately. The highest single agent (HSA) reference model was applied, which quantifies synergy as the excess over the maximum response of a single drug in the combination. Synergy between antibodies in each combination is reported as an overall synergy score (the average of observed synergy across the dose combination matrix) as well as a peak HSA score (the highest synergy score calculated across the dose combination matrix). Synergy scores of less than -10, between -10 and 10, and greater than 10 indicate antagonistic, additive, and synergistic antibody combinations, respectively. While peak HSA scores report on synergy at the most optimal combination concentrations, the overall synergy score is less affected by outlier data points. [0208] As depicted in FIGS. 7A-7C, the triple antibody combination of IMM20184/IMM20190/IMM20253, also known as IMM-BCP-01, synergized with each other to neutralize pseudovirus expressing the WA1/2020 reference, alpha/UK/B.1.1.7, Beta/S.African/B.1.351, Gamma/Brazil/P.1, and epsilon/Californian/B.1.429 spike proteins. Peak synergy scores ranged from 19.8 against the gamma variant to 61.1 against the alpha variant. Synergy was maintained against the alpha/UK variant across the entire concentration range tested. Overall additivity was observed against the other pseudoviruses. Synergy was observed against the live virus isolate Germany BavPat 1/2020 at defined ratios, with overall additivity being observed across the concentrations tested (FIG. 7B). [0209] Example 8. Predicted activity against new variants. As the SARS-CoV-2 virus continues to mutate it will be imperative to predict, and confirm, the ability of antibodies to neutralize newly arising variants. As depicted in FIG. 8 the residues critical for binding of IMM20184, IMM20190, and IMM20253 are spatially distinct from the residues mutated in the RBD of the B.1.617.2 (delta), B.1.617.3 (kappa), and C.37 (lambda) variants. Based upon the location of the L452R T478K mutations in the B.1.617.2 variant, the L452R E484Q mutations in the B.1.617.3 variant, and the L452Q F490S mutations in the lambda variant, it was predicted that the triple antibody combination would be able to neutralize those variants in a manner at least equivalent to the reference WA1/2020 strain. [0210] Pseudovirus neutralization assays were performed with RVPs, as described above, that express the B.1.617.2, B.1.617.3, or C.37 variants. Consistent with the prediction, IMM- BCP-01 neutralized the pseudoviruses in a manner that was at least equivalent to the reference WA1/2020 variant (Table 6). Neutralization curves (FIG. 9). [0211] Activity of the triple antibody cocktail against the B.1.617.2 and B.1.617.3 variants is depicted in the context of other variants in FIG. 10. Consistent with the known epitopes of the antibodies, and positions of RBD-localized mutations in the different variants, the triple antibody cocktail exhibits neutralizing activity across all variants tested. [0212] IMM20190 binds to a large epitope that encompasses two distinct regions on the RBD (FIG. 2). K417 and N501, residues known to be mutated in different variants, represent residues in each of the two binding sites. Mutation of one of those sites (N501Y), as observed in the alpha/B.1.1.7 variant, is sufficient to maintain IMM20190 activity (FIGS. 5A-5C) and provides for improved synergy with IMM20184/IMM20253. The delta plus/B.1.617.2.ay1/2 variant contains a K417N mutation. As predicted by our understanding of the IMM20190 epitope, and borne out by the results depicted in Table 6, the K417N mutation causes a partial loss of neutralization potential, the magnitude of the effect is in line with that observed against the alpha. Mutation of both K417 and N501, as observed in the beta/B.1.351 and gamma/P.1 variants, more fully abrogates IMM20190 activity, and neutralization is achieved through the IMM20184/IMM20253 antibodies. Those are reflected in the results depicted FIG. 10 and the IC50/90 values derived from those data (Table 6). Table 6.

[0214] Example 9. Triple combination is active against live virus To confirm results obtained with pseudovirus testing we performed neutralization assays on four different live virus variants under BSL3 conditions: USA/WA_CDC-WA1/2020 (reference sequence), Germany/BavPat 1/2020 (D614G), UK (B.1.1.7), and South African (B.1.351). In all cases, neutralization of the live virus recapitulated data obtained in pseudovirus neutralization assays (FIGS. 11A-11D and Table 6). Assays using the Germany/BavPat1/2020 strain were performed in a manner sufficient to assess combinatorial effects via the HSA algorithm. Data demonstrated an overall additive effect, with peak HSA scores reaching levels of synergy (FIG. 7B) [0215] Example 10. Abs neutralize virus in a hamster model of SARS-CoV-2. Antibodies capable of neutralizing live virus in vitro were assessed for the ability to neutralize virus in vivo using a hamster model of SARS-CoV-2 infection. Hamsters treated with increasing doses of PR194_00232 were infected with SARS-CoV-2 (SARS-CoV- 2/human/USA/WA_CDC-WA1/2020) and viral load in the lungs were assessed at Day 4 post inoculation of the virus using standard tissue culture infectivity assays and plaque counting. PR194_00232 was able to neutralize virus, relative to no-treatment controls, in a dose- dependent manner when dosed in the prophylactic setting (FIG. 12). Consistent with PR193_00018 and PR200_00622 working combinatorially with PR194_00232 to clear the virus, combinations consisting of PR194_00232/PR193_0018 and PR194_00232/PR200_00622 appear more effective at clearing the virus than PR194_00232 alone. [0216] When dosed in the therapeutic setting (FIG. 13), a roughly 3-log clearance of virus, relative to no treatment, was observed in 5 out of 6 animals treated with this antibody cocktail. In contrast, other dose groups exhibited a more variable response with only three animals in any other group ever reaching maximal clearance. These data suggest that optimal viral clearance requires all three antibodies to be part of the cocktail. [0217] In a follow-up study, the triple combination dosed at equimolar ratios (0.25 mg each) resulted in a statistically significant decrease in viral load in the lungs at day 4 post- inoculation, as measured with TCID50 assays (FIG. 14). To that end, in the same study doses of IMM20184 and IMM20253 were decreased to 0.125 mg each and we observed an increase in the median level of viral load in the lung compared to the cohort treated with the 1:1:1 ratio. These data provide additional support that IMM20184 and IMM20253 are contributing to in vivo efficacy, even in the context of the USA/WA_CDC-WA1/2020 viral isolate which is highly sensitive to neutralization by IMM20190 in vitro. [0218] Variability observed in the efficacy of IMM-BCP-01 in various studies led to retrospective correlation of systemic exposure post-intraperitoneal injection with overall viral clearance (FIG. 15). Syrian golden Hamsters were inoculated with 3.3x105 TCID50 doses of WA1/2020 live virus in the nasal turbinates (1.65 x 105 per nare). IMM-BCP-01 was administered i.p. 6 hours post-inoculation at three different dose levels. Dose levels were 0.1mg each (0.3mg total), 0.2mg each (0.6 mg total), or 0.3 mg each (0.9mg total). Animals were euthanized at Day 4 and viral titers in lung determined by TCID50 assays. Levels of IgG in serum at time of euthanasia were determined by anti-huIgG ELISA to correlate IgG exposure with overall viral clearance. Data support the idea that i.p. injections led to variable levels of exposure and correlated with viral clearance. Serum levels of approximately 3 – 5 ug/mL at day 4 were sufficient to achieve viral clearance and were obtained by all three dose levels tested. [0219] IMM-BCP-01 is able to clear virus from the lungs of hamsters infected with variants of concern. Hamsters were dosed prophylactically with IMM-BCP-01 one day prior to inoculation with either the Alpha (FIG. 16A) or Beta (FIG. 16B) variant and lung titers were determined on day 4 post-inoculation. IMM-BCP-01 at the lowest doses tested provided levels of viral clearance that match, or exceed, those obtained by antibodies with demonstrated clinical efficacy. In addition, increased doses of IMM-BCP-01 led to a dose- dependent improvement in viral clearance, with > four-log clearance of WA1/2020 and 2.5 log clearance of Beta at the highest doses tested. All doses tested represent clinically relevant doses. [0220] Robust activity of the cocktail was observed regardless of inoculation titer used (FIG. 17). Syrian hamsters were inoculated with either 3.3x105 TCID50 doses of WA1/2020 live virus in the nasal turbinates (1.65 x 105 per nare) or 3.3x104 TCID50 doses of WA1/2020 live virus in the nasal turbinates (1.65 x 104 per nare). Animals were then treated 6 hours post-inoculation with either vehicle or IMM-BCP-01 at 0.1mg each dose level. Robust viral clearance was observed, relative to the vehicle control, for both inoculation levels. Table 7.

Antibodies Elicit Mechanisms that Could Enhance Viral Neutralization and Clearance. Each of the antibodies comprising IMM-BCP-01 (IMM20184, IMM20190, and IMM20253) bind to both isolated RBD and Spike trimer when assessed by surface plasmon resonance (FIGS. 18A-18C). These data suggest that IMM20184 can bind avidly to the Spike trimer, as signified by the decrease off-rate (Table 7), and crosslink two Spike monomers. [0222] Consistent with its epitope overlapping with the ACE2 binding site, IMM20190 is able to compete binding of ACE2 to isolated RBD protein from the REF and Alpha variant (FIG. 19A and FIG. 19B), but its ability to compete ACE2 binding to the Beta variant is decreased (FIG. 19C), consistent with its known decreased binding and neutralization potency. IMM20184 effectively competes binding of ACE2 to all three isolated RBD (FIGS. 19A – 19C), despite binding to an epitope that is outside of known ACE2 binding site (FIG. 2). Despite exhibiting neutralization activity against both pseudovirus and live virus, IMM20253 is unable to effectively compete for ACE2 binding (FIGS. 19A-19C). This suggests the neutralization is due to a mechanism distinct from direct ACE2 competition. [0223] IMM20184, IMM20190 and IMM20253 were assessed for the ability to fix complement using standard assays [Nikitin et al., 2019]. As depicted in FIGS. 20A-20B, all three antibodies comprising IMM-BCP-01 were able to fix complement, albeit to different levels when assessed at defined concentrations. All three antibodies demonstrated a preference for fixing complement upon binding to the stabilized trimer as compared to the isolated RBD. When assessed in a concentration-dependent manner (FIG. 20C), the combination of IMM20184 and IMM20253 induced an enhanced level of complement fixation beyond what was observed by either antibody alone. That activity was further enhanced by addition of IMM20190 to the antibody cocktail. These data suggesting the antibodies comprising IMM-BCP-01 elicit a combinatorial, or synergistic, activation of complement fixation upon binding Spike. [0224] Select antibodies were also assessed for the ability to phagocytosis at a defined concentration and using methods described previously [Shi et al., 2014]. As listed in Table 8, antibodies elicited a range of phagocytosis scores, with higher values representing a more robust ability to induce phagocytosis. Each of the antibodies comprising IMM-BCP-01 was further evaluated in the ability to induce phagocytosis in a concentration-dependent manner against the full-length trimer, both as individual antibodies and as cocktails of two or three antibodies (FIG. 21). All three antibodies induce phagocytosis of the full-length trimer in concentration-dependent manners, with IMM20253 inducing the most robust activation of phagocytosis as assessed in vitro. IMM-BCP-01 exhibited enhanced activity, over a wider concentration range, as compared to any of the individual antibodies and the IMM20184/IMM20253 two antibody combination. [0225] IMM-BCP-01 induces a more robust antibody-dependent cellular cytotoxicity than any of the individual component antibodies when assessed in vitro using Promega’s ADCC Reporter Bioassay and S-expressing CHO-K1 target cells at a 2:1 effector:target cell ratio and manufacturer protocols. [0226] Taken together these data suggest that the IMM-BCP-01 cocktail robustly induces multiple effector functions in a manner that is enhanced by the presence of two or more of its constituent antibodies as compared to the individual antibodies alone. [0227] Example 12. IMM20253 may neutralize SARS-CoV-2 through a mechanism that alters Spike protein conformation. As depicted in FIG. 2, IMM20253 binds to an epitope that is on the outside face of the RBD domain of the SARS-CoV-2 RBD. When in the closed conformation, the epitope is in close proximity to the N-terminal domain of a second Spike protein within the Spike trimer. A recent paper [Sun et al, 2021] describes the isolation of nanobodies (Nb), defined as class III Nb, that bind to epitopes that appear to overlap with the IMM20253 epitope. Biochemical characterization the Class III Nb demonstrates that binding of the Nb to the Spike protein induces a conformational change to the post-fusion conformation. This presumably inactivates the virus’ ability to bind cells and provides a mechanism for the neutralization observed in vitro. Like the Class III Nbs, IMM20253 is unable to directly compete for ACE2 binding (FIGS. 20A-20C), but is able to neutralize both reference and alpha variant live virus as a single agent when measured as a function of virus internalization (Table 9). Together, these data suggest that IMM20253 binding to the outer face of the RBD may impart its intrinsic neutralization through induction of a conformational change in the Spike protein that prevents virus uptake into the cells without competing for ACE2 binding. Interestingly, IMM20253 appears to be approximately 30-times more potent against the alpha strain than the delta strain. This may be a function of the internalization kinetics of the two different variants. This difference may also underlie the strong synergy observed between the IMM20184/IMM20190/IMM20253 in the context of neutralizing the alpha variant (FIGS. 7A-7C). It should be noted that like Greaney et al [Greany e al], Sun et al describe the region around the IMM20253 epitope as being of therapeutic interest, one to which antibodies are not known to exist [Greany et al] and one that is going to be difficult for antibodies to access [Sun et al]. Consistent with these assertions, the CoVIC consortium analyzed over 300 antibodies that bind to the RBD domain of the SARS-CoV-2 Spike protein and failed to identify an antibody that bound to the IMM20253 epitope. These points all highlight the uniqueness of the IMM20253 antibody [Hastie et al]. [0228] As outlined in FIGS. 23A-23B, binding of IMM20253, but not IMM20190, induces a time-dependent conformational changed in the trimeric Spike protein. Dynamic light scattering (DLS) analysis performed at t = 0 and t = 2 hours, demonstrates that IMM20253 binding results in the complex adopting a conformation with a smaller hydrodynamic radius. In contrast, the IMM20190/Spike trimer complex maintains a similar hydrodynamic radius throughout the two hour incubation. [0229] The conformational change induced by IMM20253 results in an increased protease sensitivity of the Spike protein (FIG. 24). Cleavage of Spike, when incubated in the presence of thrombin protease, is observed at t = 1 hour. Similar results are observed when Spike is complexed with either ACE2 or IMM20190. In contrast, proteolytic cleavage of Spike, and release of S2, is observed within 15 minutes when Spike is complexed with the IMM20253. Without being bound by theory, this data suggests that the IMM20253 antibody is particularly effective against variants that have pre-cleaved Spike proteins and/or variants that are more susceptible to cleavage.

[0230] Example 13. IMM20253, alone or in combination with IMM20184, induces synergy with other ACE2-competitive antibodies. Binding of either IMM20253, IMM20184, or the combination of the two antibodies (IMM20253/IMM20184), induces combinatorial effects, preferably synergy, when combined with the ACE2-competitive antibody IMM20190. Combinations of IMM20253, IMM20184, or IMM20253/IMM20184, induces synergy with other ACE2-competing enzymes. IMM20253, IMM20184, or IMM20253/IMM20184 combines with one or more of the following antibodies to induce combinatorial, preferably synergistic, viral neutralization in vitro and promote in vivo viral clearance. Examples of antibodies that combine to induce the combinatorial effect with IMM20253, IMM20184 or IMM20253/IMM20184 include, but are not limited to, sotrovimab, casirivimab, imdevimab, bamlanivimab, etesevimab, tixagevimab, cilgavimab, ADG2, ADG10, ADG20, ADG30, and CR3022. As depicted in FIGS. 25A-25C, IMM20253 works in combination with IMM20184, as well as in-house generated versions of REGN987 (imdevimab) and REGN933 (casirivimab) when assayed against B.1.617.2 ay2 pseudovirus. Under the conditions tested all three combinations displayed synergistic neutralization at defined concentrations achievable in vivo (HSA score >10). Under the conditions tested, the IMM20253/IMM20184 combination achieved an overall HSA score indicative of synergy (12.5). IMM20253/REGN933 achieved an overall HSA score of 9.5, suggestive of additivity (HSA score between -10 and 10). The IMM20253/REGN933 combination demonstrated an overall HSA score of 5.6, consistent with additive activity under the conditions tested. All three antibodies (IMM20184, REGN933 and REGN987) block ACE2 binding. In contrast, IMM20253 in combination with in-house generated S309 (sotrovimab) resulted in strong antagonism across all concentrations tested (FIG. 26). S309 is thought to work through a non- ACE2 dependent neutralization mechanism. This suggests that IMM20253’s non-ACE2 dependent neutralization mechanism may enhance neutralization in combination with antibodies that work via an ACE2-dependent neutralization mechanism, but may antagonize other non-ACE2 dependent mechanisms of neutralization. [0231] Example 14. IMM20253 and IMM20279 and exhibit potent binding to the Spike protein of the Omicron variant. Individual antibodies were assessed, in the HTRF assay described above, using the full length Spike protein and soluble RBD domains of the Spike protein containing mutations found in the Omicron variant. FIGS. 27A-27D depict the binding of the individual antibodies to the Spike-RBD of the Omicron variant, expressed as percentage binding, relative to the binding to the reference strain. Binding of the antibodies IMM20190 and IMM20184 (FIGS. 27A and 27B), are negatively affected by the mutations within the Spike domain of the Omicron variant. In contrast, binding by the IMM20253 (FIG. 27C) and IMM20279 (FIG. 27D) antibodies are unaffected by the range of mutations within the Spike protein of the Omicron variant. The binding affinity of the IMM20279 antibody to the RBD as well as the full-length Spike protein is comparable to that of the reference strain (FIG. 27D). [0232] Example 15. IMM20253 antibody neutralizes SARS-CoV-2 pseudovirus expressing the Omicron variant. The functional consequence of the IMM20253 antibody binding to Spike was assessed. Pseudovirus infection and neutralization assays were performed by using standard methods described above. The IMM20253 antibody exhibited potent neutralization against pseudovirus expressing the Spike protein from the B.1.1.529 (Omicron) variant (FIG. 28). The neutralization activity was comparable to the activity against pseudovirus expressing the Spike protein from the reference strain (SARS-CoV- 2/human/USA/WA_CDC-WA1/2020), D614G (SARS-CoV-2/human/Germany/BavPat 1/2020), B.1.351 (beta/S. African), B.1.617.2 Ay.2 (Delta Plus) variants of SARS-CoV-2 (FIG. 28). IMM20253 exhibited equivalent neutralization of psuedovirus expressing the spike of either the BA.1 or BA.2 sub-lineage of the Omicron variant (FIG. 29). [0233] Example 16. IMM20184 and IMM20279 act to enhance IMM20253 activity in vivo. Hamsters were dosed prophylactically with IMM20253 (0.3 mg, 1 mg, or 3 mg), IMM20253/IMM20184 (0.5 mg each or 1.5 mg each), or IMM20253/IMM20279 (1.5 mg each) one day prior to inoculation with the Omicron BA.1 (FIG. 36) variant and lung titers were determined on day 4 post-inoculation by plaque forming assays. IMM20253 exhibited a dose-dependent decrease in lung titer. While IMM20184 showed a substantial decrease in in vitro binding of omicron Spike protein relative to REF (FIG. 27A) and IMM20279 also showed decreased binding of omicron Spike protein relative to REF (FIG. 27D), the combinations of the combination of IMM20253/IMM20184 and IMM20253/IMM20279 exhibits more robust clearance of Omicron BA.1 in vivo. These data suggest that the combination of IMM20253 and IMM20184 and the combination of IMM20253 and IMM20279 act combinatorially in vivo to clear the virus (FIG. 36). [0234] Example 17. CryoEM structures of IMM20184, IMM20290, IMM20253, and IMM20279 in complex with the SARS-CoV-2 spike protein. The structures of antibodies in complex with the intact trimer of the SARS-CoV-2 trimer were solved by cryoEM to a resolution of approximately 7 Angstroms (FIGS 30A-30B, FIGS. 31A-31B, FIGS. 32A-32B, and FIGS. 34A-34B). The cryoEM structures corroborated the binding sites for IMM20184, IMM20190, and IMM20253 that were determined by alanine scanning mutagenesis (Table 5). IMM20279 binds to a site that appears to overlap with the binding site of IMM20184. [0235] Three Fabs of IMM20190 bind simultaneously to the trimer in a manner consistent with the Class 1 binders as defined by the CoVIC consortium and induce all three RBDs to adopt the up conformation (FIGS. 30A-30B). Three Fabs of IMM20184 bind simultaneously to the spike trimer, perpendicular to the vertical axis of the spike. Binding appears to induce a large conformational change in the spike trimer, particularly in the RBD domains. A similar reorganization of the spike trimer is observed in the cryoEM structure obtained for the IMM20279/Spike trimer complex (FIGS. 35A-35B). IMM20279 binds to similar regions on RBD as compared to IMM20184, but does so by binding from a different angle of attack. It binds at approximately a 45 degree angle to the vertical axis of the spike as compared to the 90 degree angle adopted by IMM20184. [0236] Only a single FAb of IMM20253 is ever observed to bind to the intact trimer (FIGS. 32A-32B). Binding results in loss of density in the cryoEM structure associated with the RBD and N-terminal domain of spike monomer that is not bound by the Fab fragment. This loss of density is consistent with destabilization of those structures upon Fab binding. Consistent with destabilization of the trimer, monomeric S protein is observed in the cryoEM imaging. Increasing the ratio of Ab:Spike from 3:1 to 6:1 results in almost complete loss of intact spike. These data provide structural evidence that support the biochemical data demonstrating increased protease sensitivity upon IMM20253, but not IMM20190 binding. Destabilization of the spike may provide the basis for neutralization through a non-ACE2 competitive mechanism. [0237] Higher resolution cryoEM structures (approximately 3. 9 Angstroms) of IMM20184 and IMM20253 Fab fragments in a trimeric complex with an isolated RBD were solved to better define the epitopes of those two antibodies. As depicted in FIG. 33 and FIGS. 34A-34B the structures of the ternary complex are in agreement with those obtained with the intact trimer. Residues within 4 Angstroms of the variable domains of each Fab are depicted in spheres. Those residues include all residues identified by alanine scanning. Residues buried by IMM20253 interaction with the RBD are conserved in the Omicron variant and provide additional basis for continued activity of this antibody against the variant. [0238] Example 18 Phase 1 Study to Evaluate the Safety, Pharmacokinetics, and Viral Clearance of Single Ascending Doses of IMM-BCP-01 Administered Intravenously in Adults with Mild to Moderate COVID [0239] This is a randomized, double-blind, placebo-controlled Phase 1 study to evaluate the safety, PK, and viral clearance of single ascending doses of IV IMM-BCP-01 in subjects with mild to moderate COVID-19 caused by infection with SARS-CoV-2 and/or its variants. [0240] The primary objective of this study is to evaluate the safety and tolerability of intravenous (IV) IMM-BCP-01 in subjects with mild to moderate COVID-19 through Day 28. [0241] The secondary objectives of the study are to: Determine PK and evaluate viral clearance after single ascending doses of IV IMM-BCP-01 in subjects with mild to moderate COVID-19 through Day 28.

The total duration of a subject's participation is approximately 90 days. [0243] Subjects presenting at the clinic with signs and symptoms of mild to moderate COVID-19 and agreeing to participate in the study are screened, and if deemed eligible for the study, are randomized (2:1) to receive a single IV dose of IMM-BCP-01 or placebo on Day 1.
