FIELD OF THE DISCLOSURE

The disclosure relates to anti-Yellow Fever Virus (YFV) antibodies and antigen-binding fragments thereof, and compositions containing such antibodies and antigen-binding fragments thereof, and therapeutic and diagnostic uses for the antibodies, antigen-binding fragments, and compositions.

BACKGROUND OF THE DISCLOSURE

Yellow Fever Virus (YFV) is a mosquito-borne flavivirus found in tropical and subtropical areas of Africa and South America. It is transmitted to humans primarily through the bite of infected Aedes or Haemagogus mosquito species and has three distinct transmission cycles: 1) jungle or sylvatic cycle; 2) African savannah (intermediate) cycle; and 3) urban cycle. (www.cdc.gov/yellowfever/transmission/index.html). While many people infected with YFV are asymptomatic, others develop symptoms such as fever, chills, headache, low back pain, myalgia, loss of appetite, nausea, vomiting, and/or fatigue following an incubation period of 3-6 days. (www.who.int/news-room/fact-sheets/detail/yellow-fever). Roughly 15% of people infected develop a severe form of YFV that includes high fever, bleeding diatheses, adominal pain, renal failure, cardiovascular instability, and liver failure; up to 50% of patients with the severe form of YFV will die. (McGuinness et al, Neurohospitalist 2017, 7(4); 157-158).

YFV has a RNA genome of 10,862 nucleotides that encode three structural and seven non-structural proteins. From the 5′ terminus, the order of the encoded proteins is: C; prM/M; E; NS1; NS2A; NS2B; NS3; NS4A; NS4B and NS5. The three structural proteins include the C (capsid) protein, the membrane protein, M, and the envelope protein, E. The envelope protein plays an important role in cell tropism, virulence, and immunity.

Live attenuated 17D vaccine is considered one of the safest and most efficacious vaccines developed to date. However, despite the availability of the vaccine, Yellow Fever remains a serious public health issue. There are some data suggesting immunity, though protective, may wane over time in certain populations. Additionally, YFV outbreaks in non-endemic countries (such as the 11 imported cases in China in 2016) and concurrent outbreaks exhausting stockpiles of 17D have underscored the importance of developing a treatment.

Indeed, to date there are currently no approved YFV treatments (the only course being supportive therapy) and, despite decades of research, the development of safe and effective therapeutic antibodies against YFV has remained elusive. The YFV E-specific serum antibody response has been shown to be overwhelmingly mediated by antibodies targeting domain I (DI) and/or domain II (DII) of the E protein, whereas antibodies targeting domain III (DIII) are absent or present at very low titers (DVratskikh et al. PLoS pathogens 9, e1003458 (2013)). Correspondingly, the six YFV E-specific human monoclonal antibodies described to date all target overlapping epitopes within DII of the E protein (Lu et al. Cell Reports 26, 438-446 e435 (2019); Daffis et al. Virology 337, 262-272 (2005)). Recently, the crystal structure of one of these mAbs (5A) in complex with a soluble YFV E dimer was determined, which showed that this mAb binds to a conserved neutralizing epitope within DII of one E monomer (Lu et al. Cell Reports 26, 438-446 e435 (2019)). Therefore, there remains a need for highly specific, high affinity, and highly potent neutralizing anti-YFV antibodies and antigen-binding fragments thereof.

SUMMARY OF THE DISCLOSURE

The disclosure pertains to the discovery of antibodies and antigen-binding fragments thereof that bind to YFV protein and exhibit neutralizing potency, in particular antibodies binding to the domain III (DIII) of the E protein that exhibit high neutralization potency. The antibodies of the present disclosure may also cross-react with other flaviviruses, e.g., display binding reactivity to DENV-2, DENV-4, WNV, and/or ZIKV E proteins. An extensive panel of YFV-specific monoclonal antibodies is described. Binding studies demonstrated that the neutralizing antibody response to YFV-17D is primarily mediated by antibodies that recognize FL proximal epitopes within DII of the YFV E protein. A small set of DIII-targeting antibodies having potent neutralizing activity was also identified. Additionally, binding assays revealed that YFV-17D vaccination appears to induce a subset of antibodies that display broad flavivirus binding activity, the majority of which target the highly conserved FL and show little to no cross-neutralizing activity. Neutralization studies showed a proportion of antibodies display highly potent neutralizing activity. Altogether, the panel of antibodies described herein provides promising therapeutic candidates and a framework for the rational design of YFV vaccines.

Such antibodies may be useful when administered prophylactically (prior to exposure to the virus and infection with the virus) to lessen the severity, or duration of a primary infection with YFV, or ameliorate at least one symptom associated with the infection. The antibodies may be used alone or in conjunction with a second agent useful for treating an YFV infection. In certain embodiments, the antibodies may be given therapeutically (after exposure to and infection with the virus) either alone, or in conjunction with a second agent to lessen the severity or duration of the primary infection, or to ameliorate at least one symptom associated with the infection. In certain embodiments, the antibodies may be used prophylactically as stand-alone therapy to protect patients who are at risk for acquiring an infection with YFV, such as those described above. Any of these patient populations may benefit from treatment with the antibodies of the disclosure, when given alone or in conjunction with a second agent, including for example, an anti-viral therapy, or other anti-viral vaccines.

DETAILED DESCRIPTION OF THE DISCLOSURE

An in-depth understanding of the human antibody response to YFV infection will aid the development and evaluation of YFV vaccine and therapeutic and/or prophylactic antibodies for the treatment and/or prevention of YFV infection. A high-throughput antibody isolation platform was used to dissect the human memory B cell response to YFV in two vaccinated adult donors and highly potent and selective YFV-neutralizing antibodies were isolated and characterized.

High-throughput epitope mapping studies revealed that epitopes within or proximal to the FL on DII of the YFV E protein are immunodominant. While many of the mAbs that bound to FL-specific epitopes were non-neutralizing, most of the mAbs that targeted FL-proximal epitopes overlapping the 5A epitope showed neutralizing activity. Furthermore, the vast majority of potent nAbs recognized this antigenic site suggesting that the nAb response induced by YFV-17D vaccination is primarily mediated by this class of Abs. A subset of these mAbs displayed exceptionally potent neutralizing activity, with IC₅₀ s that were about 10 times lower than previously described YFV mAbs. Given the recent YFV outbreaks in Brazil and the Democratic Republic of Congo, coupled with YFV-17D vaccine supply shortages and the lack of effective treatments for YFV disease, these mAbs represent promising candidates for prophylaxis and/or therapy

Accordingly, disclosed herein are highly selective and potent anti-YFV antibodies, as well as possible vaccine candidates, for the treatment and/or prophylaxis of YFV infection. Additionally, the reagents disclosed here provide a useful set of tools for the evaluation of clinical trials, which will be critical for selecting the optimal YFV vaccination or antibody-based therapeutic strategy from those currently under investigation.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. In this specification and in the claims that follow, reference will be made to a number of terms that shall be defined to have the following meanings:

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise.

“Optional” or “optionally” means that the subsequently described event or circumstance can or cannot occur, and that the description includes instances where the event or circumstance occurs and instances where it does not.

The term “about” when used before a numerical designation, e.g., temperature, time, amount, concentration, and such other, including a range, indicates approximations which may vary by (+) or (−) 10%, 5%, 1%, or any subrange or subvalue there between. Preferably, the term “about” when used with regard to an amount means that the amount may vary by +/−10%.

“Comprising” or “comprises” is intended to mean that the compositions and methods include the recited elements, but not excluding others. “Consisting essentially of” when used to define compositions and methods, shall mean excluding other elements of any essential significance to the combination for the stated purpose. Thus, a composition consisting essentially of the elements as defined herein would not exclude other materials or steps that do not materially affect the basic and novel characteristic(s) of the claimed invention. “Consisting of” shall mean excluding more than trace elements of other ingredients and substantial method steps. Embodiments defined by each of these transition terms are within the scope of this disclosure.

“Yellow Fever Virus”, also referred to as “YFV”, is an RNA virus typically spread by the bite of infected Aedes or Haemagogus species mosquito bites.

The term “YFV-17D” refers to the attenuated YFV vaccine strain developed by passaging a wild-type Asibi strain in chicken and mouse tissue. There are three 17D substrains in current production: 17DD manufactured in Brazil, 17D-213 manufactured in Russia, and 17D-204 manufactured in China, France, Senegal, and the USA. While the mechanism of attenuation is poorly understood, it is hypothesized that the limited genetic diversity of the 17D vaccine virus attributes to vaccine attenuation and safety. There is evidence that replication of 17D is not as error-prone as wild-type RNA viruses. See Pugachev et al., J Virol. 78(2):1032-8 (2004).

The term “envelope protein” or “E protein” refers to the structural YFV protein that is a primary immunogen that plays a central role in receptor binding and membrane fusion. The structure of the E protein ectodomain (the soluble N-terminal portion consisting of 395 residues) includes three distinct structural domains, referred to as domains I, II, and III. (Volk et al., Virology 2009, 394(1): 12-18). Domain II contains a S-S bridge stabilized loop at its distal end that functions as a highly conserved fusion loop (FL). When a virus enters a target host cell, the FL of Domain II is exposed and inserts into the host cellular membrane. (Zhang et al., Viruses 2017, 9(11): 338). In some embodiments, the antibodies and antigen-binding fragments thereof bind to the FL of Domain II YFV E protein. In other embodiments, the antibodies and antigen-binding fragments thereof bind to Domain III of the YFV E protein.

The development of an effective YFV therapeutic has presented a number of unique challenges. The in-depth analysis of the human antibody response to the YFV vaccine performed here provides insights for the development of such a therapeutic treatment. The antibody repertoire analysis disclosed herein reveals that the majority of neutralizing YFV-specific antibodies target FL-proximal epitopes overlapping the 5A epitope, whereas a small number of potent neutralizing antibodies targeted the DIII domain—a region of the E protein that, until now, was not the epitope for any effective anti-YFV antibodies.

The term “epitope” refers to an antigenic determinant that interacts with a specific antigen binding site in the variable region of an antibody molecule known as a paratope. A single antigen may have more than one epitope. Thus, different antibodies may bind to different areas on an antigen and may have different biological effects. The term “epitope” also refers to a site on an antigen to which B and/or T cells respond. It also refers to a region of an antigen that is bound by an antibody. Epitopes may be defined as structural or functional. Functional epitopes are generally a subset of the structural epitopes and have those residues that directly contribute to the affinity of the interaction. Epitopes may also be conformational, that is, composed of non-linear amino acids. In certain embodiments, epitopes may include determinants that are chemically active surface groupings of molecules such as amino acids, sugar side chains, phosphoryl groups, or sulfonyl groups, and, in certain embodiments, may have specific three-dimensional structural characteristics, and/or specific charge characteristics. The term “antibody” (or “Ab”), as used herein, is intended to refer to immunoglobulin molecules comprised of four polypeptide chains, two heavy (H) chains and two light (L) chains interconnected by disulfide bonds (i.e., “full antibody molecules”), as well as multimers thereof (e.g. IgM) or antigen-binding fragments thereof.

The terms “antigen-binding portion”, “antigen-binding fragment”, and the like, as used herein, include any naturally occurring, enzymatically obtainable, synthetic, or genetically engineered polypeptide or glycoprotein that specifically binds an antigen to form a complex. In certain embodiments, the terms “antigen-binding portion” or “antibody fragment”, as used herein, refer to one or more fragments of an antibody that retains the ability to bind to YFV.

An antibody fragment may include a Fab fragment, a F(ab′)₂ fragment, a Fv fragment, a dAb fragment, a fragment containing a CDR, or an isolated CDR. Antigen-binding fragments of an antibody may be derived, e.g., from full antibody molecules using any suitable standard techniques such as proteolytic digestion or recombinant genetic engineering techniques involving the manipulation and expression of DNA encoding antibody variable and (optionally) constant domains. Such DNA is known and/or is readily available from, e.g., commercial sources, DNA libraries (including, e.g., phage-antibody libraries), or can be synthesized. The DNA may be sequenced and manipulated chemically or by using molecular biology techniques, for example, to arrange one or more variable and/or constant domains into a suitable configuration, or to introduce codons, create cysteine residues, modify, add or delete amino acids, etc.

Non-limiting examples of antigen-binding fragments include: (i) Fab fragments; (ii) F(ab′)2 fragments; (iii) Fd fragments; (iv) Fv fragments; (v) single-chain Fv (scFv) molecules; (vi) dAb fragments; and (vii) minimal recognition units consisting of the amino acid residues that mimic the hypervariable region of an antibody (e.g., an isolated complementarity determining region (CDR) such as a CDR3 peptide), or a constrained FR3-CDR3-FR4 peptide. Other engineered molecules, such as domain-specific antibodies, single domain antibodies, domain-deleted antibodies, chimeric antibodies, CDR-grafted antibodies, diabodies, triabodies, tetrabodies, minibodies, nanobodies (e.g. monovalent nanobodies, bivalent nanobodies, etc.), small modular immunopharmaceuticals (SMIPs), and shark variable IgNAR domains, are also encompassed within the expression “antigen-binding fragment,” as used herein.

An antigen-binding fragment of an antibody will typically comprise at least one variable domain. The variable domain may be of any size or amino acid composition and will generally comprise at least one CDR, which is adjacent to or in frame with one or more framework sequences. In antigen-binding fragments having a V_H domain associated with a V_L domain, the V_H and V_L domains may be situated relative to one another in any suitable arrangement. For example, the variable region may be dimeric and contain V_H-V_H, V_H-V_L or V_L-V_L dimers. Alternatively, the antigen-binding fragment of an antibody may contain a monomeric V_H or V_L domain.

In certain embodiments, an antigen-binding fragment of an antibody may contain at least one variable domain covalently linked to at least one constant domain. Non-limiting, exemplary configurations of variable and constant domains that may be found within an antigen-binding fragment of an antibody of the present disclosure include: (i) V_H-C_H1; (ii) V_H-C_H2; (iii) V_H-C_H3; (iv) V_H-C_H1-C_H2; (V) V_H-C_H1-C_H2-C_H3; (vi) V_H-C_H2-C_H3; (vii) V_H-CL; (viii) V_L-C_H1; (ix) V_L-C_H2; (x) V_L-C_H3; (xi) V_L-C_H1-C_H2; (xii) V_L-C_H1-C_H2-C_H3; (xiii) V_L-C_H2-C_H3; and (xiv) V_L-C_L. In any configuration of variable and constant domains, including any of the exemplary configurations listed above, the variable and constant domains may be either directly linked to one another or may be linked by a full or partial hinge or linker region. A hinge region may consist of at least 2 (e.g., 5, 10, 15, 20, 40, 60 or more) amino acids, which result in a flexible or semi-flexible linkage between adjacent variable and/or constant domains in a single polypeptide molecule. Moreover, an antigen-binding fragment of an antibody of the present disclosure may comprise a homo-dimer or hetero-dimer (or other multimer) of any of the variable and constant domain configurations listed above in non-covalent association with one another and/or with one or more monomeric V_H or V_L domain (e.g., by disulfide bond(s)).

As with full antibody molecules, antigen-binding fragments may be mono-specific or multi-specific (e.g., bi-specific). A multi-specific antigen-binding fragment of an antibody will typically comprise at least two different variable domains, wherein each variable domain is capable of specifically binding to a separate antigen or to a different epitope on the same antigen. Any multi-specific antibody format, including the exemplary bi-specific antibody formats disclosed herein, may be adapted for use in the context of an antigen-binding fragment of an antibody of the present disclosure using routine techniques available in the art.

Each heavy chain is comprised of a heavy chain variable region (“HCVR” or “V_H”) and a heavy chain constant region (comprised of domains C_H1, C_H2, and C_H3). Each light chain is comprised of a light chain variable region (“LCVR or “V_L”) and a light chain constant region (CO. The V_H and V_L regions can be further subdivided into regions of hypervariability, termed complementarity determining region (CDR), interspersed with regions that are more conserved, termed framework regions (FR). Each V_H and V_L is composed of three CDRs and four FRs, arranged from amino-terminus to carboxy-terminus in the following order: FR1, CDR1, FR2, CDR2, FR3, CDR3, FR4. In certain embodiments of the disclosure, the FRs of the antibody (or antigen binding fragment thereof) may be identical to the human germline sequences, or may be naturally or artificially modified. An amino acid consensus sequence may be defined based on a side-by-side analysis of two or more CDRs. Accordingly, the CDRs in a heavy chain are designated “CDRH1”, “CDRH2”, and “CDRH3”, respectively, and the CDRs in a light chain are designated “CDRL1”, “CDRL2”, and “CDRL3”.

In some embodiments, the present disclosure provides an antibody comprising a YFV binding domain, CDRH1, wherein the CDRH1 binding domain comprises a consensus motif, the consensus motif comprising the sequence: X₁ SIX₂X₃X₄X₅X₆WX₇, wherein X₁ is G or I, X₂ is S or T, X₃ is S, T, G, or no amino acid, X₄ is D, S, T, or G, X₅ is Y, N, or D, X₆ is Wo r Y, and X₇ is S or T. The following clones include this consensus motif: ADI-45083; ADI-42225; ADI-48900; ADI-42786; ADI-42210; ADI-49188; ADI-42188; ADI-42818; ADI-42151; ADI-48913; ADI-46722; ADI-49141; ADI-46741; ADI-46739; ADI-50539; ADI-50538; and ADI-50533.

In some embodiments, the present disclosure provides an antibody comprising a YFV binding domain, CDRH1, wherein the CDRH1 binding domain comprises a consensus motif, the consensus motif comprising the sequence: FX1FSDX2YMX3 (SEQ ID NO:1014), wherein X1 is I or T, X2 is H or Y, and X3 is A or D. The following clones include this consensus motif: ADI-42191; ADI-49040; ADI-42223; ADI-42193; ADI-48968; ADI-42212; ADI-45126; ADI-42141; ADI-49140; ADI-48894; ADI-42226; ADI-49137; ADI-48890; ADI-42206; and ADI-49030.

Substitution of one or more CDR residues or omission of one or more CDRs is also possible. Antibodies have been described in the scientific literature in which one or two CDRs can be dispensed with for binding. Padlan et al. (1995 FASEB J. 9:133-139) analyzed the contact regions between antibodies and their antigens, based on published crystal structures, and concluded that only about one fifth to one third of CDR residues actually contact the antigen. Padlan also found many antibodies in which one or two CDRs had no amino acids in contact with an antigen (see also, Vajdos et al. 2002 J Mol Biol 320:415-428).

CDR residues not contacting antigen can be identified based on previous studies (for example residues H60-H65 in CDRH2 are often not required), from regions of Kabat CDRs lying outside Chothia CDRs, by molecular modeling and/or empirically. If a CDR or residue(s) thereof is omitted, it is usually substituted with an amino acid occupying the corresponding position in another human antibody sequence or a consensus of such sequences. Positions for substitution within CDRs and amino acids to substitute can also be selected empirically.

The fully human monoclonal antibodies disclosed herein may comprise one or more amino acid substitutions, insertions and/or deletions in the framework and/or CDR regions of the heavy and light chain variable domains as compared to the corresponding germline sequences. Such mutations can be readily ascertained by comparing the amino acid sequences disclosed herein to germline sequences available from, for example, public antibody sequence databases. The present disclosure includes antibodies, and antigen-binding fragments thereof, which are derived from any of the amino acid sequences disclosed herein, wherein one or more amino acids within one or more framework and/or CDR regions are mutated to the corresponding residue(s) of the germline sequence from which the antibody was derived, or to the corresponding residue(s) of another human germline sequence, or to a conservative amino acid substitution of the corresponding germline residue(s) (such sequence changes are referred to herein collectively as “germline mutations”). A person of ordinary skill in the art, starting with the heavy and light chain variable region sequences disclosed herein, can easily produce numerous antibodies and antigen-binding fragments which comprise one or more individual germline mutations or combinations thereof. In certain embodiments, all of the framework and/or CDR residues within the V_H and/or V_L domains are mutated back to the residues found in the original germline sequence from which the antibody was derived. In other embodiments, only certain residues are mutated back to the original germline sequence, e.g., only the mutated residues found within the first 8 amino acids of FR1 or within the last 8 amino acids of FR4, or only the mutated residues found within CDR1, CDR2 or CDR3. In other embodiments, one or more of the framework and/or CDR residue(s) are mutated to the corresponding residue(s) of a different germline sequence (i.e., a germline sequence that is different from the germline sequence from which the antibody was originally derived). Furthermore, the antibodies of the present disclosure may contain any combination of two or more germline mutations within the framework and/or CDR regions, e.g., wherein certain individual residues are mutated to the corresponding residue of a particular germline sequence while certain other residues that differ from the original germline sequence are maintained or are mutated to the corresponding residue of a different germline sequence. Once obtained, antibodies and antigen-binding fragments that contain one or more germline mutations can be easily tested for one or more desired property such as, improved binding specificity, increased binding affinity, improved or enhanced antagonistic or agonistic biological properties (as the case may be), reduced immunogenicity, etc. Antibodies and antigen-binding fragments obtained in this general manner are encompassed within the present disclosure.

The present disclosure also includes fully monoclonal antibodies comprising variants of any of the CDR amino acid sequences disclosed herein having one or more conservative substitutions. For example, the present disclosure includes antibodies having CDR amino acid sequences with, e.g., 10 or fewer, 8 or fewer, 6 or fewer, 4 or fewer, etc. conservative amino acid substitutions relative to any of the CDR amino acid sequences disclosed herein. In some embodiments, the anti-YFV antibodies and antigen-binding fragments disclosed are human antibodies. The term “human antibody”, as used herein, is intended to include antibodies having variable and constant regions derived from human germline immunoglobulin sequences. The human antibodies of the disclosure may include amino acid residues not encoded by human germline immunoglobulin sequences (e.g., mutations introduced by random or site-specific mutagenesis in vitro or by somatic mutation in vivo), for example in the CDRs and in particular CDR3.

In some embodiments, the anti-YFV antibodies and antigen-binding fragments disclosed are recombinant antibodies. The term “recombinant” generally refers to any protein, polypeptide, or cell expressing a gene of interest that is produced by genetic engineering methods. The term “recombinant” as used with respect to a protein or polypeptide, means a polypeptide produced by expression of a recombinant polynucleotide. The proteins used in the immunogenic compositions of the disclosure may be isolated from a natural source or produced by genetic engineering methods.

The antibodies of the disclosure may, in some embodiments, be recombinant human antibodies. The term “recombinant human antibody”, as used herein, is intended to include all antibodies, including human or humanized antibodies, that are prepared, expressed, created or isolated by recombinant means, such as antibodies expressed using a recombinant expression vector transfected into a host cell (described further below), antibodies isolated from a recombinant, combinatorial human antibody library (described further below), antibodies isolated from an animal (e.g., a mouse) that is transgenic for human immunoglobulin genes (see e.g., Taylor et al. (1992) Nucl. Acids Res. 20:6287-6295) or antibodies prepared, expressed, created or isolated by any other means that involves splicing of human immunoglobulin gene sequences to other DNA sequences. Such recombinant human antibodies have variable and constant regions derived from human germline immunoglobulin sequences. In certain embodiments, however, such recombinant human antibodies are subjected to in vitro mutagenesis (or, when an animal transgenic for human Ig sequences is used, in vivo somatic mutagenesis) and thus the amino acid sequences of the V_H and V_L regions of the recombinant antibodies are sequences that, while derived from and related to human germline V_H and V_L sequences, may not naturally exist within the human antibody germline repertoire in vivo.

In some embodiments, the anti-YFV antitbodies and antigen-binding fragments thereof are isolated antibodies. An “isolated antibody”, as used herein, refers to an antibody that is substantially free of other antibodies having different antigenic specificities (e.g., an isolated antibody that specifically binds YFV, or a fragment thereof, is substantially free of Abs that specifically bind antigens other than YFV). In some embodiments, the anti-YFV antibodies and antigen-binding fragments specifically bind to the YFV E protein, e.g., the FL of DII domain or DIII. The term “specifically binds,” or “binds specifically to”, or the like, means that an antibody or antigen-binding fragment thereof forms a complex with an antigen that is relatively stable under physiologic conditions. Specific binding can be characterized by an equilibrium dissociation constant of at least about 1×10⁻⁶ M or less (e.g., a smaller K_D denotes a tighter binding). Methods for determining whether two molecules specifically bind are well known in the art and include, for example, equilibrium dialysis, surface plasmon resonance, and the like. As described herein, antibodies have been identified by surface plasmon resonance, e.g., BIACORE™, biolayer interferometry measurements using, e.g., a ForteBio Octet HTX instrument (Pall Life Sciences), which bind specifically to YFV. Moreover, multi-specific antibodies that bind to YFV protein and one or more additional antigens, or a bi-specific that binds to two different regions of YFV are nonetheless considered antibodies that “specifically bind”, as used herein. In certain embodiments, the antibodies disclosed herein display equilibrium dissociation constants (and hence specificities) of about 1×10⁻⁶ M; about 1×10⁻⁷ M; about 1×10⁻⁸M; about 1×10⁻⁹ M; about 1×10⁻¹⁰ M; between about 1×10⁻⁶ M and about 1×10⁻⁷ M; between about 1×10⁻⁷M and about 1×10⁻⁸M; between about 1×10⁻⁸M and about 1×10⁻⁹M; between about 1×10⁻⁹M and about 1×10⁻¹⁰ M; or between about 1×10⁻⁹M and about 1×10⁻¹⁰ M.

In some embodiments, the anti-YFV antibodies and antigen-binding fragments are high affinity binders. The term “high affinity” refers to those mAbs having a binding affinity to YFV, expressed as K_D, of at least 10⁻⁹M; more preferably 10⁻¹⁰ M, more preferably 10⁻¹¹ M, more preferably 10⁻¹²M as measured by surface plasmon resonance, e.g., BIACORE™, biolayer interferometry measurements using, e.g., a ForteBio Octet HTX instrument (Pall Life Sciences), or solution-affinity ELISA.

By the term “slow off rate”, “Koff” or “kd” is meant an antibody that dissociates from YFV, with a rate constant of 1×10⁻³ s⁻¹ or less, preferably 1×10⁻⁴ s⁻¹ or less, as determined by surface plasmon resonance, e.g., BIACORE™ or a ForteBio Octet HTX instrument (Pall Life Sciences).

The specific embodiments, antibody or antibody fragments of the disclosure may be conjugated to a therapeutic moiety (“immunoconjugate”), such as an antibiotic, a second anti-YFV antibody, a vaccine, or a toxoid, or any other therapeutic moiety useful for treating a YFV infection.

Also contemplated are antibodies and antigen-binding fragments substantially identical to the antibodies provided herein. The term “substantial identity”, or “substantially identical,” when referring to a nucleic acid or fragment thereof, indicates that, when optimally aligned with appropriate nucleotide insertions or deletions with another nucleic acid (or its complementary strand), there is nucleotide sequence identity in at least about 90%, and more preferably at least about 95%, 96%, 97%, 98% or 99% of the nucleotide bases, as measured by any well-known algorithm of sequence identity, such as FASTA, BLAST or GAP, as discussed below. Accordingly, nucleic acid sequences that display a certain percentage “identity” share that percentage identity, and/or are that percentage “identical” to one another. A nucleic acid molecule having substantial identity to a reference nucleic acid molecule may, in certain instances, encode a polypeptide having the same or substantially similar amino acid sequence as the polypeptide encoded by the reference nucleic acid molecule.

In certain embodiments, isolated nucleic acid sequences are provided that encode the antibodies and antigen-binding fragments thereof, wherein such nucleic acid sequences comprise sequences that encode the heavy chain (HC) amino acid sequences of any one of the antibodies designated Antibody Number 1 through Antibody Number 152 as disclosed in Table 3

In certain embodiments, isolated nucleic acid sequences are provided that encode the antibodies and antigen-binding fragments thereof, wherein such nucleic acid sequences comprise sequences that encode the heavy chain (LC) amino acid sequences of any one of the antibodies designated Antibody Number 1 through Antibody Number 152 as disclosed in Table 3. As applied to polypeptides, the term “substantial identity” or “substantially identical” means that two peptide sequences, when optimally aligned, such as by the programs GAP or BESTFIT using default gap weights, share at least 90% sequence identity, even more preferably at least 95%, 98% or 99% sequence identity. Accordingly, amino acid sequences that display a certain percentage “identity” share that percentage identity, and/or are that percentage “identical” to one another. Accordingly, amino acid sequences that display a certain percentage “identity” share that percentage identity, and/or are that percentage “identical” to one another.

In certain embodiments, the disclosed antibody amino acid sequences are, e.g.: at least 70% identical; at least 75% identical; 80% identical; at least 85% identical; at least 90% identical; at least 95% identical; at least 96% identical; at least 97% identical; at least 98% identical; at least 99%; and/or all percentages of identity in between; to other sequences and/or share such percentage identities with one another (or with certain subsets of the herein-disclosed antibody sequences).

Preferably, residue positions, which are not identical, differ by conservative amino acid substitutions. A “conservative amino acid substitution” is one in which an amino acid residue is substituted by another amino acid residue having a side chain (R group) with similar chemical properties (e.g., charge or hydrophobicity). In general, a conservative amino acid substitution will not substantially change the functional properties of a protein. In cases where two or more amino acid sequences differ from each other by conservative substitutions, the percent or degree of similarity may be adjusted upwards to correct for the conservative nature of the substitution. Means for making this adjustment are well known to those of skill in the art. (See, e.g., Pearson (1994) Methods Mol. Biol. 24: 307-331). Examples of groups of amino acids that have side chains with similar chemical properties include 1) aliphatic side chains: glycine, alanine, valine, leucine and isoleucine; 2) aliphatic-hydroxyl side chains: serine and threonine; 3) amide-containing side chains: asparagine and glutamine; 4) aromatic side chains: phenylalanine, tyrosine, and tryptophan; 5) basic side chains: lysine, arginine, and histidine; 6) acidic side chains: aspartate and glutamate, and 7) sulfur-containing side chains: cysteine and methionine. Preferred conservative amino acids substitution groups are: valine-leucine-isoleucine, phenylalanine-tyrosine, lysine-arginine, alanine-valine, glutamate-aspartate, and asparagine-glutamine. Alternatively, a conservative replacement is any change having a positive value in the PAM250 log-likelihood matrix disclosed in Gonnet et al. (1992) Science 256: 1443 45. A “moderately conservative” replacement is any change having a nonnegative value in the PAM250 log-likelihood matrix.

Sequence similarity for polypeptides is typically measured using sequence analysis software. Protein analysis software matches similar sequences using measures of similarity assigned to various substitutions, deletions and other modifications, including conservative amino acid substitutions. For instance, GCG software contains programs such as GAP and BESTFIT which can be used with default parameters to determine sequence homology or sequence identity between closely related polypeptides, such as homologous polypeptides from different species of organisms or between a wild type protein and a mutein thereof. See, e.g., GCG Version 6.1. Polypeptide sequences also can be compared using FASTA with default or recommended parameters; a program in GCG Version 6.1. FASTA (e.g., FASTA2 and FASTA3) provides alignments and percent sequence identity of the regions of the best overlap between the query and search sequences (Pearson (2000) supra). Another preferred algorithm when comparing a sequence of the disclosure to a database containing a large number of sequences from different organisms is the computer program BLAST, especially BLASTP or TBLASTN, using default parameters. (See, e.g., Altschul et al. (1990) J. Mol. Biol. 215: 403 410 and (1997) Nucleic Acids Res. 25:3389 402).

In certain embodiments, the antibody or antibody fragment for use in the method of the disclosure may be mono-specific, bi-specific, or multi-specific. Multi-specific antibodies may be specific for different epitopes of one target polypeptide or may contain antigen-binding domains specific for epitopes of more than one target polypeptide.

As disclosed herein, anti-YFV antibodies may be obtained from human B cells using techniques available to the artisan, and, for example, as described in the EXAMPLES below. Methods for generating human antibodies in transgenic animals, such as mice, are also known in the art and may be employed in order to derive antibodies in accordance with the present disclosure. Any such known methods can be used in the context of the present disclosure to make human antibodies that specifically bind to YFV (see, for example, U.S. Pat. No. 6,596,541).

In certain embodiments, the antibodies of the instant disclosure possess affinities (K_D) ranging from about 1.0×10-⁷M to about 1.0×10⁻¹²M, when measured by binding to antigen either immobilized on solid phase or in solution phase. In certain embodiments, the antibodies of the disclosure possess affinities (K_D) ranging from about 1×10⁻⁷ M to about 6×10⁻¹⁰ M, when measured by binding to antigen either immobilized on solid phase or in solution phase. In certain embodiments, the antibodies of the disclosure possess affinities (K_D) ranging from about 1×10⁻⁷ M to about 9×10⁻¹⁰M, when measured by binding to antigen either immobilized on solid phase or in solution phase.

In addition to the specific anti-YFV antibodies and antibody fragments disclosed herein, the present disclosure also contemplates variants of those antibodies and antibody fragments that maintain bioequivalency. Such variant antibodies and antibody fragments comprise one or more additions, deletions, or substitutions of amino acids when compared to parent sequence, but exhibit biological activity that is essentially equivalent to that of the described antibodies. Likewise, the antibody-encoding DNA sequences of the present disclosure encompass sequences that comprise one or more additions, deletions, or substitutions of nucleotides when compared to the disclosed sequence, but that encode an antibody or antibody fragment that is essentially bioequivalent to an antibody or antibody fragment of the disclosure.

Two antigen-binding proteins, or antibodies, are considered bioequivalent if, for example, they are pharmaceutical equivalents or pharmaceutical alternatives whose rate and extent of absorption do not show a significant difference when administered at the same molar dose under similar experimental conditions, either single does or multiple dose. Some antibodies will be considered equivalents or pharmaceutical alternatives if they are equivalent in the extent of their absorption but not in their rate of absorption and yet may be considered bioequivalent because such differences in the rate of absorption are intentional and are reflected in the labeling, are not essential to the attainment of effective body drug concentrations on, e.g., chronic use, and are considered medically insignificant for the particular drug product studied.

In one embodiment, two antigen-binding proteins are bioequivalent if there are no clinically meaningful differences in their safety, purity, and potency.

In one embodiment, two antigen-binding proteins are bioequivalent if a patient can be switched one or more times between the reference product and the biological product without an expected increase in the risk of adverse effects, including a clinically significant change in immunogenicity, or diminished effectiveness, as compared to continued therapy without such switching.

In one embodiment, two antigen-binding proteins are bioequivalent if they both act by a common mechanism or mechanisms of action for the condition or conditions of use, to the extent that such mechanisms are known.

Bioequivalence may be demonstrated by in vivo and/or in vitro methods. Bioequivalence measures include, e.g., (a) an in vivo test in humans or other mammals, in which the concentration of the antibody or its metabolites is measured in blood, plasma, serum, or other biological fluid as a function of time; (b) an in vitro test that has been correlated with and is reasonably predictive of human in vivo bioavailability data; (c) an in vivo test in humans or other mammals in which the appropriate acute pharmacological effect of the antibody (or its target) is measured as a function of time; and (d) in a well-controlled clinical trial that establishes safety, efficacy, or bioavailability or bioequivalence of an antibody.

Bioequivalent variants of the antibodies of the disclosure may be constructed by, for example, making various substitutions of residues or sequences or deleting terminal or internal residues or sequences not needed for biological activity. For example, cysteine residues not essential for biological activity can be deleted or replaced with other amino acids to prevent formation of unnecessary or incorrect intramolecular disulfide bridges upon renaturation. In other contexts, bioequivalent antibodies may include antibody variants comprising amino acid changes, which modify the glycosylation characteristics of the antibodies, e.g., mutations that eliminate or remove glycosylation.

Biological and Biophysical Characteristics of the Antibodies

In certain embodiments, the inventive antibodies and antigen-binding fragments thereof specifically bind to YFV, wherein at least one of the CDRH1, CDRH2, CDRH3, CDRL1, CDRL2, and/or CDRL3 amino acid sequences is at least 70% identical; at least 75% identical; 80% identical; at least 85% identical; at least 90% identical; at least 95% identical; at least 96% identical; at least 97% identical; at least 98% identical; at least 99%; and/or all percentages of identity in between; to the corresponding CDRH1, CDRH2, CDRH3, CDRL1, CDRL2, and/or CDRL3 amino acid sequence as disclosed in Table 3 of an antibody selected from Antibody Number 1 through Antibody Number 152 as disclosed in Table 3.

In some embodiments, the anti-YFV antibodies and antigen-binding fragments thereof are neutralizing antibodies, i.e., exhibit neutralizing potency. A “neutralizing antibody”, as used herein (or an “antibody that neutralizes YFV activity” or “an antibody with neutralizing activity”), refers to an antibody whose binding to an antigen, e.g., the YFV E protein as the case may be as disclosed herein, results in inhibition of at least one biological activity. For example, an antibody of the disclosure may aid in blocking the fusion of YFV to a host cell, or prevent syncytia formation, or prevent the primary disease caused by YFV. Alternatively, an antibody of the disclosure may demonstrate the ability to ameliorate at least one symptom of the YFV infection. This inhibition of the biological activity of YFV can be assessed by measuring one or more indicators of YFV biological activity by one or more of several standard in vitro assays (such as a neutralization assay, as described herein) or in vivo assays known in the art (for example, animal models to look at protection from challenge with YFV following administration of one or more of the antibodies described herein).

In certain embodiments, the antibodies and antigen-binding fragments thereof display an in vitro neutralization potency (IC₅₀) of between about 0.5 microgram/milliliter (μg/ml) to about 5 μg/ml; between about 0.05 μg/ml to about 0.5 μg/ml; or less than about 0.05 mg/ml.

The term “IC₅₀” refers to the “half maximal inhibitory concentration”, which value measures the effectiveness of compound (e.g. anti-YFV antibody) inhibition towards a biological or biochemical utility. This quantitative measure indicates the quantity required for a particular inhibitor to inhibit a given biological process by half. In certain embodiments, YFV neutralization potencies for anti-YFV neutralizing antibodies disclosed herein are expressed as neutralization IC₅₀ values. Of the anitbodies described herein, generally the antibodies binding to DIII of the YFV E protein possess the highest neutralization potency.

In some embodiments, the antibodies and antigen-binding fragments thereof cross-react with DENV-2, DENV-4, WNV, or ZIKV E proteins, i.e., bind to YFV E protein and an E protein from one or more of the other flaviviruses. In certain embodiments, such antibodies and antigen-binding fragments thereof bind to DENV-2, DENV-4, WNV, YFV, and ZIKV E proteins with high apparent avid affinities (K_D^Apps<10 nM). In certain embodiments, the cross-reactive antibodies or antigen-binding fragments thereof have neutralizing activity against YFV-17D and another flavivirus. In certain embodiments, the cross-reactive antibodies and antigen-binding fragments thereof bind to the FL epitope. In certain embodiments, the cross-reactive antibodies and antigen-binding fragments thereof bind to DIII. In a certain embodiment, the cross-reactive antibody is ADI-48905.

Epitope Binning and Related Technologies

As described above and as demonstrated in the EXAMPLES, Applicant has characterized the epitopic binning of the inventive antibodies and antigen-binding fragments thereof. In addition to the methods for conducting such characterization, various other techniques are available to the artisan that can be used to carry out such characterization or to otherwise ascertain whether an antibody “interacts with one or more amino acids” within a polypeptide or protein. Exemplary techniques include, for example, a routine cross-blocking assay such as that described Antibodies, Harlow and Lane (Cold Spring Harbor Press, Cold Spring Harb., N.Y.) can be performed. Other methods include alanine scanning mutational analysis, peptide blot analysis (Reineke (2004) Methods Mol Biol 248:443-63), peptide cleavage analysis crystallographic studies and NMR analysis. In addition, methods such as epitope excision, epitope extraction and chemical modification of antigens can be employed (Tomer (2000) Protein Science 9: 487-496). Another method that can be used to identify the amino acids within a polypeptide with which an antibody interacts is hydrogen/deuterium exchange detected by mass spectrometry. In general terms, the hydrogen/deuterium exchange method involves deuterium-labeling the protein of interest, followed by binding the antibody to the deuterium-labeled protein. Next, the protein/antibody complex is transferred to water and exchangeable protons within amino acids that are protected by the antibody complex undergo deuterium-to-hydrogen back-exchange at a slower rate than exchangeable protons within amino acids that are not part of the interface. As a result, amino acids that form part of the protein/antibody interface may retain deuterium and therefore exhibit relatively higher mass compared to amino acids not included in the interface. After dissociation of the antibody, the target protein is subjected to protease cleavage and mass spectrometry analysis, thereby revealing the deuterium-labeled residues that correspond to the specific amino acids with which the antibody interacts. See, e.g., Ehring (1999) Analytical Biochemistry 267 (2):252-259; Engen and Smith (2001) Anal. Chem. 73:256A-265A.

As the artisan will understand, an epitope can be formed both from contiguous amino acids or noncontiguous amino acids juxtaposed by tertiary folding of a protein. Epitopes formed from contiguous amino acids are typically retained on exposure to denaturing solvents, whereas epitopes formed by tertiary folding are typically lost on treatment with denaturing solvents. An epitope typically includes at least 3, and more usually, at least 5 or 8-10 amino acids in a unique spatial conformation.

Modification-Assisted Profiling (MAP), also known as Antigen Structure-based Antibody Profiling (ASAP) is a method that categorizes large numbers of monoclonal antibodies (mAbs) directed against the same antigen according to the similarities of the binding profile of each antibody to chemically or enzymatically modified antigen surfaces (US 2004/0101920). Each category may reflect a unique epitope either distinctly different from or partially overlapping with an epitope represented by another category. This technology allows rapid filtering of genetically identical antibodies, such that characterization can be focused on genetically distinct antibodies. When applied to hybridoma screening, MAP may facilitate identification of rare hybridoma clones that produce mAbs having the desired characteristics. MAP may be used to sort the antibodies of the disclosure into groups of antibodies binding different epitopes.

As the artisan understands, one can easily determine whether an antibody binds to the same epitope as, or competes for binding with, a reference anti-YFV antibody by using routine methods available in the art. For example, to determine if a test antibody binds to the same epitope as a reference YFV antibody of the disclosure, the reference antibody is allowed to bind to a YFV protein or peptide under saturating conditions. Next, the ability of a test antibody to bind to the YFV molecule is assessed. If the test antibody is able to bind to YFV following saturation binding with the reference anti-YFV antibody, it can be concluded that the test antibody binds to a different epitope than the reference anti-YFV antibody. On the other hand, if the test antibody is not able to bind to the YFV molecule following saturation binding with the reference anti-YFV antibody, then the test antibody may bind to the same epitope as the epitope bound by the reference anti-YFV antibody of the disclosure.

To determine if an antibody competes for binding with a reference anti-YFV antibody, the above-described binding methodology is performed in two orientations: In a first orientation, the reference antibody is allowed to bind to a YFV molecule under saturating conditions followed by assessment of binding of the test antibody to the YFV molecule. In a second orientation, the test antibody is allowed to bind to a YFV molecule under saturating conditions followed by assessment of binding of the reference antibody to the YFV molecule. If, in both orientations, only the first (saturating) antibody is capable of binding to the YFV molecule, then it is concluded that the test antibody and the reference antibody compete for binding to YFV. As will be appreciated by a person of ordinary skill in the art, an antibody that competes for binding with a reference antibody may not necessarily bind to the identical epitope as the reference antibody, but may sterically block binding of the reference antibody by binding an overlapping or adjacent epitope.

Two antibodies bind to the same or overlapping epitope if each competitively inhibits (blocks) binding of the other to the antigen. That is, a 1-, 5-, 10-, 20- or 100-fold excess of one antibody inhibits binding of the other by at least 50% but preferably 75%, 90% or even 99% as measured in a competitive binding assay (see, e.g., Junghans et al., Cancer Res. (1990) 50:1495-1502). Alternatively, two antibodies have the same epitope if essentially all amino acid mutations in the antigen that reduce or eliminate binding of one antibody reduce or eliminate binding of the other. Two antibodies have overlapping epitopes if some amino acid mutations that reduce or eliminate binding of one antibody reduce or eliminate binding of the other.

Additional routine experimentation (e.g., peptide mutation and binding analyses) can then be carried out to confirm whether the observed lack of binding of the test antibody is in fact due to binding to the same epitope as the reference antibody or if steric blocking (or another phenomenon) is responsible for the lack of observed binding. Experiments of this sort can be performed using ELISA, RIA, surface plasmon resonance, flow cytometry or any other quantitative or qualitative antibody-binding assay available in the art.

Immunoconjugates

The disclosure encompasses a human YFV monoclonal antibody conjugated to a therapeutic moiety (“immunoconjugate”), such as an agent that is capable of reducing the severity of primary infection with YFV, or to ameliorate at least one symptom associated with YFV infection, including fever, muscle pains, headache, vomiting, diarrhea, bleeding, or the severity thereof. Such an agent may be a second different antibody to YFV, or a vaccine. The type of therapeutic moiety that may be conjugated to the anti-YFV antibody will take into account the condition to be treated and the desired therapeutic effect to be achieved. Alternatively, if the desired therapeutic effect is to treat the sequelae or symptoms associated with YFV infection, or any other condition resulting from such infection, such as, but not limited to, disseminated intravascular coagulation, acute kidney failure, and acute respiratory distress syndrome, it may be advantageous to conjugate an agent appropriate to treat the sequelae or symptoms of the condition, or to alleviate any side effects of the antibodies of the disclosure. Examples of suitable agents for forming immunoconjugates are known in the art, see for example, WO 05/103081.

Multi-Specific Antibodies

The antibodies of the present disclosure may be mono-specific, bi-specific, or multi-specific. Multi-specific antibodies may be specific for different epitopes of one target polypeptide or may contain antigen-binding domains specific for more than one target polypeptide. See, e.g., Tutt et al., 1991, J. Immunol. 147:60-69; Kufer et al., 2004, Trends Biotechnol. 22:238-244. The antibodies of the present disclosure can be linked to or co-expressed with another functional molecule, e.g., another peptide or protein. For example, an antibody or fragment thereof can be functionally linked (e.g., by chemical coupling, genetic fusion, noncovalent association or otherwise) to one or more other molecular entities, such as another antibody or antibody fragment to produce a bi-specific or a multi-specific antibody with a second binding specificity.

Therapeutic Administration and Formulations

The disclosure provides therapeutic compositions comprising the inventive anti-YFV antibodies or antigen-binding fragments thereof. The administration of therapeutic compositions in accordance with the disclosure will be administered with suitable carriers, excipients, and other agents that are incorporated into formulations to provide improved transfer, delivery, tolerance, and the like. A multitude of appropriate formulations can be found in the formulary known to all pharmaceutical chemists: Remington's Pharmaceutical Sciences, Mack Publishing Company, Easton, Pa. These formulations include, for example, powders, pastes, ointments, jellies, waxes, oils, lipids, lipid (cationic or anionic) containing vesicles (such as LIPOFECTIN™), DNA conjugates, anhydrous absorption pastes, oil-in-water and water-in-oil emulsions, emulsions carbowax (polyethylene glycols of various molecular weights), semi-solid gels, and semi-solid mixtures containing carbowax. See also Powell et al. “Compendium of excipients for parenteral formulations” PDA (1998) J Pharm Sci Technol 52:238-311.

The dose of each of the antibodies of the disclosure may vary depending upon the age and the size of a subject to be administered, target disease, conditions, route of administration, and the like. When the antibodies of the present disclosure are used for treating a YFV infection, or for treating one or more symptoms associated with a YFV infection, such as the fever, nausea, or muscle aches associated with a YFV infection in a patient, or for lessening the severity of the disease, it is advantageous to administer each of the antibodies of the present disclosure intravenously or subcutaneously. Normally, each of the antibodies would be administered at a single dose of about 0.01 to about 30 mg/kg body weight, more preferably about 0.1 to about 20 mg/kg body weight, or about 0.1 to about 15 mg/kg body weight, or about 0.02 to about 7 mg/kg body weight, about 0.03 to about 5 mg/kg body weight, or about 0.05 to about 3 mg/kg body weight, or about 1 mg/kg body weight, or about 3.0 mg/kg body weight, or about 10 mg/kg body weight, or about 20 mg/kg body weight. Multiple doses may be administered as necessary. Depending on the severity of the condition, the frequency and the duration of the treatment can be adjusted. In certain embodiments, the antibodies or antigen-binding fragments thereof of the disclosure can be administered as an initial dose of at least about 0.1 mg to about 800 mg, about 1 to about 600 mg, about 5 to about 300 mg, or about 10 to about 150 mg, to about 100 mg, or to about 50 mg. In certain embodiments, the initial dose may be followed by administration of a second or a plurality of subsequent doses of the antibodies or antigen-binding fragments thereof in an amount that can be approximately the same or less than that of the initial dose, wherein the subsequent doses are separated by at least 1 day to 3 days; at least one week, at least 2 weeks; at least 3 weeks; at least 4 weeks; at least 5 weeks; at least 6 weeks; at least 7 weeks; at least 8 weeks; at least 9 weeks; at least 10 weeks; at least 12 weeks; or at least 14 weeks.

Various delivery systems are known and can be used to administer the pharmaceutical composition of the disclosure, e.g., encapsulation in liposomes, microparticles, microcapsules, recombinant cells capable of expressing the mutant viruses, receptor mediated endocytosis (see, e.g., Wu et al. (1987) J. Biol. Chem. 262:4429-4432). Methods of introduction include, but are not limited to, intradermal, transdermal, intramuscular, intraperitoneal, intravenous, subcutaneous, intranasal, epidural and oral routes. The composition may be administered by any convenient route, for example by infusion or bolus injection, by absorption through epithelial or mucocutaneous linings {e.g., oral mucosa, nasal mucosa, rectal and intestinal mucosa, etc.) and may be administered together with other biologically active agents. Administration can be systemic or local. It may be delivered as an aerosolized formulation (See US2011/0311515 and US2012/0128669). The delivery of agents useful for treating respiratory diseases by inhalation is becoming more widely accepted (See A. J. Bitonti and J. A. Dumont, (2006), Adv. Drug Deliv. Rev, 58:1 106-1 1 18). In addition to being effective at treating local pulmonary disease, such a delivery mechanism may also be useful for systemic delivery of antibodies (See Maillet et al. (2008), Pharmaceutical Research, Vol. 25, No. 6, 2008).

The pharmaceutical composition can be also delivered in a vesicle, in particular a liposome (see, for example, Langer (1990) Science 249:1527-1533).

In certain situations, the pharmaceutical composition can be delivered in a controlled release system. In one embodiment, a pump may be used. In another embodiment, polymeric materials can be used. In yet another embodiment, a controlled release system can be placed in proximity of the composition's target, thus requiring only a fraction of the systemic dose.

The injectable preparations may include dosage forms for intravenous, subcutaneous, intracutaneous and intramuscular injections, drip infusions, etc. These injectable preparations may be prepared by methods publicly known. For example, the injectable preparations may be prepared, e.g., by dissolving, suspending or emulsifying the antibody or its salt described above in a sterile aqueous medium or an oily medium conventionally used for injections. As the aqueous medium for injections, there are, for example, physiological saline, an isotonic solution containing glucose and other auxiliary agents, etc., which may be used in combination with an appropriate solubilizing agent such as an alcohol (e.g., ethanol), a polyalcohol (e.g., propylene glycol, polyethylene glycol), a nonionic surfactant [e.g., polysorbate 80, HCO-50 (polyoxyethylene (50 mol) adduct of hydrogenated castor oil)], etc. As the oily medium, there are employed, e.g., sesame oil, soybean oil, etc., which may be used in combination with a solubilizing agent such as benzyl benzoate, benzyl alcohol, etc. The injection thus prepared is preferably filled in an appropriate ampoule.

A pharmaceutical composition of the present disclosure can be delivered subcutaneously or intravenously with a standard needle and syringe. In addition, with respect to subcutaneous delivery, a pen delivery device readily has applications in delivering a pharmaceutical composition of the present disclosure. Such a pen delivery device can be reusable or disposable. A reusable pen delivery device generally utilizes a replaceable cartridge that contains a pharmaceutical composition. Once all of the pharmaceutical composition within the cartridge has been administered and the cartridge is empty, the empty cartridge can readily be discarded and replaced with a new cartridge that contains the pharmaceutical composition. The pen delivery device can then be reused. In a disposable pen delivery device, there is no replaceable cartridge. Rather, the disposable pen delivery device comes prefilled with the pharmaceutical composition held in a reservoir within the device. Once the reservoir is emptied of the pharmaceutical composition, the entire device is discarded.

Numerous reusable pen and autoinjector delivery devices have applications in the subcutaneous delivery of a pharmaceutical composition of the present disclosure. Examples include, but certainly are not limited to AUTOPEN™ (Owen Mumford, Inc., Woodstock, UK), DISETRONIC™ pen (Disetronic Medical Systems, Burghdorf, Switzerland), HUMALOG MIX 75/25™ pen, HUMALOG™ pen, HUMALIN 70/30™ pen (Eli Lilly and Co., Indianapolis, Ind.), NOVOPEN™ I, II and III (Novo Nordisk, Copenhagen, Denmark), NOVOPEN JUNIOR™ (Novo Nordisk, Copenhagen, Denmark), BD™ pen (Becton Dickinson, Franklin Lakes, N.J.), OPTIPEN™, OPTIPEN PRO™, OPTIPEN STARLET™, and OPTICLIK™ (Sanofi-Aventis, Frankfurt, Germany), to name only a few. Examples of disposable pen delivery devices having applications in subcutaneous delivery of a pharmaceutical composition of the present disclosure include, but certainly are not limited to the SOLOSTAR™ pen (Sanofi-Aventis), the FLEXPEN™ (Novo Nordisk), and the KWIKPEN™ (Eli Lilly), the SURECLICK™ Autoinjector (Amgen, Thousand Oaks, Calif.), the PENLET™ (Haselmeier, Stuttgart, Germany), the EPIPEN (Dey, L.P.) and the HUMIRA™ Pen (Abbott Labs, Abbott Park, Ill.), to name only a few.

Advantageously, the pharmaceutical compositions for oral or parenteral use described above are prepared into dosage forms in a unit dose suited to fit a dose of the active ingredients. Such dosage forms in a unit dose include, for example, tablets, pills, capsules, injections (ampoules), suppositories, etc. The amount of the aforesaid antibody contained is generally about 5 to about 500 mg per dosage form in a unit dose; especially in the form of injection, it is preferred that the aforesaid antibody is contained in about 5 to about 100 mg and in about 10 to about 250 mg for the other dosage forms.

Administration Regimens

In some embodiments, a therapeutically effective amount of an anti-YFV antibody or antigen-binding fragment thereof is provided to a subject in feed thereof, e.g., infected with YFV or at risk for infection with YFV. By the phrase “therapeutically effective amount” is meant an amount that produces the desired effect for which it is administered. The exact amount will depend on the purpose of the treatment, and will be ascertainable by one skilled in the art using known techniques (see, for example, Lloyd (1999) The Art, Science and Technology of Pharmaceutical Compounding).

According to certain embodiments, multiple doses of an antibody to YFV may be administered to a subject over a defined time course. The methods according to this aspect of the disclosure comprise sequentially administering to a subject multiple doses of an antibody to YFV. As used herein, “sequentially administering” means that each dose of antibody to YFV is administered to the subject at a different point in time, e.g., on different days separated by a predetermined interval (e.g., hours, days, weeks or months). The present disclosure includes methods which comprise sequentially administering to the patient a single initial dose of an antibody to YFV, followed by one or more secondary doses of the antibody to YFV and optionally followed by one or more tertiary doses of the antibody to YFV.

The terms “initial dose,” “secondary doses,” and “tertiary doses,” refer to the temporal sequence of administration of the antibody to YFV. Thus, the “initial dose” is the dose which is administered at the beginning of the treatment regimen (also referred to as the “baseline dose”); the “secondary doses” are the doses which are administered after the initial dose; and the “tertiary doses” are the doses which are administered after the secondary doses. The initial, secondary, and tertiary doses may all contain the same amount of antibody to YFV, but generally may differ from one another in terms of frequency of administration. In certain embodiments, however, the amount of antibody to YFV contained in the initial, secondary and/or tertiary doses vary from one another (e.g., adjusted up or down as appropriate) during the course of treatment. In certain embodiments, two or more (e.g., 2, 3, 4, or 5) doses are administered at the beginning of the treatment regimen as “loading doses” followed by subsequent doses that are administered on a less frequent basis (e.g., “maintenance doses”).

In one exemplary embodiment of the present disclosure, each secondary and/or tertiary dose is administered 1 to 26 (e.g., 1, 1½, 2, 2½, 3, 3½, 4, 4½, 5, 5½, 6, 6½, 7, 7½, 8, 8½, 9, 9½, 10, 10½, 11, 11½, 12, 12½, 13, 13½, 14, 14½, 15, 15½, 16, 16½, 17, 17½, 18, 18½, 19, 19½, 20, 20½, 21, 21½, 22, 22½, 23, 23½, 24, 24½, 25, 25½, 26, 26½, or more) weeks after the immediately preceding dose. The phrase “the immediately preceding dose,” as used herein, means, in a sequence of multiple administrations, the dose of antibody to YFV which is administered to a patient prior to the administration of the very next dose in the sequence with no intervening doses.

The methods according to this aspect of the disclosure may comprise administering to a patient any number of secondary and/or tertiary doses of an antibody to YFV. For example, in certain embodiments, only a single secondary dose is administered to the patient. In other embodiments, two or more (e.g., 2, 3, 4, 5, 6, 7, 8, or more) secondary doses are administered to the patient. Likewise, in certain embodiments, only a single tertiary dose is administered to the patient. In other embodiments, two or more (e.g., 2, 3, 4, 5, 6, 7, 8, or more) tertiary doses are administered to the patient.

In embodiments involving multiple secondary doses, each secondary dose may be administered at the same frequency as the other secondary doses. For example, each secondary dose may be administered to the patient 1 to 2 weeks after the immediately preceding dose. Similarly, in embodiments involving multiple tertiary doses, each tertiary dose may be administered at the same frequency as the other tertiary doses. For example, each tertiary dose may be administered to the patient 2 to 4 weeks after the immediately preceding dose. Alternatively, the frequency at which the secondary and/or tertiary doses are administered to a patient can vary over the course of the treatment regimen. The frequency of administration may also be adjusted during the course of treatment by a physician depending on the needs of the individual patient following clinical examination.

Accordingly, in certain embodiments are provided pharmaceutical compositions comprising: one or more of the inventive antibodies or antigen-binding fragments thereof disclosed herein and throughout and a pharmaceutically acceptable carrier and/or one or more excipients. In certain other embodiments are provided pharmaceutical compositions comprising: one or more nucleic acid sequences encoding one or more inventive antibodies or antigen-binding fragments thereof; or one or more the expression vectors harboring such nucleic acid sequences; and a pharmaceutically acceptable carrier and/or one or more excipients.

Therapeutic Uses of the Antibodies

The anti-YFV antibodies disclosed herein may be used to treat a subject with YFV and/or prevent YFV infection.

As used herein, the terms “treat,” “treatment” and “treating” refer to the reduction or amelioration of the progression, severity, and/or duration of a YFV infection, or a symptom or condition related thereto (such as fever, chills, headache, low back pain, myalgia, loss of appetite, nausea, vomiting, fatigue, or a combination thereof) resulting from the administration of one or more therapies (including, but not limited to, the administration of one or more prophylactic or therapeutic agents). In certain embodiments, such terms refer to the reduction or inhibition of the replication of YFV, the inhibition or reduction in the spread of YFV to other subjects, the inhibition or reduction of infection of a cell with YFV, or the amelioration of one or more symptoms associated with a YFV infection.

As used herein, the terms “prevent,” “preventing,” and “prevention” refer to the prevention or inhibition of the development or onset of a YFV infection or condition related thereto in a subject, the prevention or inhibition of the progression of a YFV infection or a condition related thereto resulting from the administration of a therapy (e.g., a prophylactic or therapeutic agent), the prevention of a symptom of a YFV infection or condition related thereto, or the administration of a combination of therapies (e.g., a combination of prophylactic or therapeutic agents). As used herein, the terms “ameliorate” and “alleviate” refer to a reduction or diminishment in the severity a condition or any symptoms thereof.

Due to their binding to and interaction with YFV, it is believed that the inventive antibodies and antigen-binding fragments thereof are useful—without wishing to be bound to any theory—for preventing fusion of the virus with the host cell membrane, for preventing cell to cell virus spread, and for inhibition of syncytia formation. Alternatively, the antibodies of the present disclosure may be useful for ameliorating at least one symptom associated with the infection, such as fever, diarrhea, and bleeding, or for lessening the severity, duration, and/or frequency of the infection. The antibodies of the disclosure are also contemplated for prophylactic use in patients at risk for developing or acquiring a YFV infection. It is contemplated that the antibodies of the disclosure may be used alone, or in conjunction with a second agent, or third agent for treating YFV infection, or for alleviating at least one symptom or complication associated with the YFV infection, such as fever, nausea, or muscle aches associated with, or resulting from such an infection. The second or third agents may be delivered concurrently with the antibodies of the disclosure, or they may be administered separately, either before or after the antibodies of the disclosure. The second or third agent may be an anti-viral, an NSAID or other agents to reduce fever or pain, another second but different antibody that specifically binds YFV, an agent (e.g. an antibody) that binds to another YFV antigen, a vaccine against YFV, and an siRNA specific for a YFV antigen.

In yet a further embodiment of the disclosure the present antibodies are used for the preparation of a pharmaceutical composition for treating patients suffering from a YFV infection. In yet another embodiment of the disclosure the present antibodies are used for the preparation of a pharmaceutical composition for reducing the severity of a primary infection with YFV, or for reducing the duration of the infection, or for reducing at least one symptom associated with the YFV infection. In a further embodiment of the disclosure the present antibodies are used as adjunct therapy with any other agent useful for treating an YFV infection, including an antiviral, a toxoid, a vaccine, a second YFV antibody, or any other antibody specific for a YFV antigen, or any other palliative therapy known to those skilled in the art.

Combination Therapies

As noted above, according to certain embodiments, the disclosed methods comprise administering to the subject one or more additional therapeutic agents in combination with an antibody to YFV. As used herein, the expression “in combination with” means that the additional therapeutic agents are administered before, after, or concurrent with the pharmaceutical composition comprising the anti-YFV antibody. The term “in combination with” also includes sequential or concomitant administration of the anti-YFV antibody and a second therapeutic agent.

For example, when administered “before” the pharmaceutical composition comprising the anti-YFV antibody, the additional therapeutic agent may be administered about 72 hours, about 60 hours, about 48 hours, about 36 hours, about 24 hours, about 12 hours, about 10 hours, about 8 hours, about 6 hours, about 4 hours, about 2 hours, about 1 hour, about 30 minutes, about 15 minutes or about 10 minutes prior to the administration of the pharmaceutical composition comprising the anti-YFV antibody.

Administration “concurrent” or with the pharmaceutical composition comprising the anti-YFV antibody means that the additional therapeutic agent is administered to the subject in a separate dosage form within less than 5 minutes (before, after, or at the same time) of administration of the pharmaceutical composition comprising the anti-YFV antibody, or administered to the subject as a single combined dosage formulation comprising both the additional therapeutic agent and the anti-YFV antibody.

Combination therapies may include an anti-YFV antibody of the disclosure and any additional therapeutic agent that may be advantageously combined with an antibody of the disclosure, or with a biologically active fragment of an antibody of the disclosure.

For example, a second or third therapeutic agent may be employed to aid in reducing the viral load in the liver, such as an antiviral. The antibodies may also be used in conjunction with other therapies, as noted above, including a toxoid, a vaccine specific for YFV, a second antibody specific for YFV, or an antibody specific for another YFV antigen.

Diagnostic Uses of the Antibodies

The inventive anti-YFV antibodies and antigen-binding fragments thereof may also be used to detect and/or measure YFV in a sample, e.g., for diagnostic purposes. It is envisioned that confirmation of an infection thought to be caused by YFV may be made by measuring the presence of the virus through use of any one or more of the antibodies of the disclosure. Exemplary diagnostic assays for YFV may comprise, e.g., contacting a sample, obtained from a patient, with an anti-YFV antibody of the disclosure, wherein the YFV antibody is labeled with a detectable label or reporter molecule or used as a capture ligand to selectively isolate the virus containing the protein from patient samples. Alternatively, an unlabeled YFV antibody can be used in diagnostic applications in combination with a secondary antibody which is itself detectably labeled. The detectable label or reporter molecule can be a radioisotope, such as ³H, ¹⁴C, ³²P, ³⁵S, or ¹²⁵I; a fluorescent or chemiluminescent moiety such as fluorescein isothiocyanate, or rhodamine; or an enzyme such as alkaline phosphatase, β-galactosidase, horseradish peroxidase, or luciferase. Specific exemplary assays that can be used to detect or measure YFV in a sample include enzyme-linked immunosorbent assay (ELISA), radioimmunoassay (RIA), and fluorescence-activated cell sorting (FACS).

Samples that can be used in YFV diagnostic assays according to the present disclosure include any tissue or fluid sample obtainable from a patient, which contains detectable quantities of YFV protein, or fragments thereof, under normal or pathological conditions. Generally, levels of YFV in a particular sample obtained from a healthy patient (e.g., a patient not afflicted with a disease or condition associated with the presence of YFV) will be measured to initially establish a baseline, or standard, level of YFV protein. This baseline level of YFV can then be compared against the levels of YFV measured in samples obtained from individuals suspected of having an YFV infection, or symptoms associated with such infection.

Examples

The human antibody response to YFV was comprehensively profiled by isolating and characterizing 152 YFV-specific monoclonal antibodies from the memory B cells of two flavivirus-naive donors following immunization with YFV-17D, and these antibodies were then used to map the antigenic topology of YFV. The anti-YFV antibodies obtained were found to bind several antigenic sites, most commonly targeting an epitope within or proximal to the FL of Domain II of the YFV E protein and, thus, providing support for the development of YFV antibodies that target Domain II. However, a second less common class of antibodies with highly potent neutralizing activity were found to target DIII of the virus. Such DIII-directed antibodies may be particularly valuable in the context of therapeutic application of monoclonal antibodies or cocktails as this epitope is subdominant in the natural immune response. Taken together, these results have implications for the design and evaluation of YFV vaccine and antibody-based therapeutic candidates and offer new options for passive prophylaxis.

Study design: Two flavivirus-naïve healthy adult donors (“Donor 8” and “Donor 9”) were immunized with the YFV-17D vaccine (Stamaril; Sanofi) and blood samples were collected at 10, 14, 28, 90, 180, 270, and 360 days post-vaccination. Serum neutralizing activity against YFV-17D appeared in both donors by day 14 post-vaccination and persisted through the course of the study (FIG. 1A). Pre-vaccination sera from both donors lacked reactivity with YFV-17D and showed no detectable neutralizing activity against YFV-17D (data not shown) and also lacked reactivity with E and NS1 proteins from other commonly circulating flaviviruses, i.e., dengue virus serotypes 1-4 (DENV1-4), JEV, TBEV, West Nile virus (WNV) and Zika virus (ZIKV), confirming that both donors were likely flavivirus-naïve at the time of vaccination (data not shown).

Molecular and Functional Characterization of YFV-17D Induced Plasmablast Response

Plasmablast responses in both donors were monitored at 10 and 14 days post-vaccination. In both donors, expanded plasmablast populations were observed at both 10 and 14-day time points that were approximately 10-fold greater than pre-vaccination levels (FIG. 2A). Approximately 300 plasmablasts from each donor were sorted and amplified the corresponding VH and VL regions by single-cell PCR. 161 and 210 natively-paired antibodies were cloned from Donor 8 and Donor 9, respectively, and expressed as full-length IgGs in an engineered strain of Saccharomyces cerevisiae. Sequence analysis showed the plasmablast responses were highly diverse in both donors, with only about 15% of clones belonging to expanded clonal lineages (data not shown). A large fraction of plasmablast-derived antibodies from both donors contained high levels of somatic hypermutation (SHM), suggesting efficient recruitment of MBCs into the PB response (data not shown). The median level of SHM in the PB-derived mAbs was significantly higher on Day 10 than Day 14. Correspondingly, a larger proportion of mAbs cloned from day 14 PBs lacked SHM, suggesting an increased recruitment of cells from the naïve B cell compartment at this time point (data not shown).

To analyze whether the somatic mutations in the PB-derived mAbs contribute to binding activity, inferred unmutated common ancestor (UCA) mAbs were generated from three somatically mutated PB clones and their binding affinities to a recombinant YFV E protein were measured. In all three cases, the UCA mAbs showed substantially reduced binding affinities compared to the mature mAbs, suggesting that somatic mutations in the PB mAbs are important for recognition of YFV E (FIG. 3).

PB-derived mAbs were then tested for binding reactivity to YFV-17D particles using a sandwich ELISA assay (FIG. 2B). The frequency of YFV-17D binding mAbs isolated from day 10 and 14 PBs ranged from 8-41%. 45 and 46 YFV-17D binding mAbs were recovered from the expanded PB populations in Donor 8 and 9, respectively, and then analyzed the neutralizing activities of the mAbs in a micro-titer neutralization assay at 100 and 10 nM concentrations. Neutralizing activities ranged from complete neutralization at 10 nM to no detectable neutralization at 100 nM (FIG. 2C). A higher fraction of mAbs isolated from day 14 PBs displayed neutralizing activity compared to those isolated from day 10 PBs, which is consistent with the increased serum neutralizing activity on day 14 versus day 10 in both donors (data not shown). Neutralization titration experiments on the mAbs displaying at least 50% infection inhibition at 100 nM revealed that 9-12% of YFV-17D binding mAbs isolated from day 14 PBs displayed medium to high neutralizing activity (IC₅₀s≤10 nM) (FIG. 2D and FIG. 4). Sequence analysis showed that 12.5-33% of the PB-derived nAbs utilized VH4-4/VL1-51 germline gene pairing, suggesting recognition of a common antigenic site (data not shown).

About 50% and 22% of the neutralizing antibodies isolated from donor 8 and 9, respectively, lacked somatic mutations, indicating that YFV-17D neutralizing antibodies are present in the naïve B cell repertoire and suggesting that YFV-17D vaccination induces PB responses that originate from both naïve and MBCs, and only a minority of these B cells encode Abs that display neutralizing activity. See FIGS. 1A and 1B.

Molecular and Functional Characterization of YFV-17D Induced MBC Response

MBC responses in both donors were monitored by collecting PBMCs at days 14, 28, 90, 180, 270, and 360 post-vaccination and purified B cells were stained with a panel of previously described B cell surface markers (CD19, CD20, CD27, IgM, IgD, CD21, and CD71) and a fluorescently-labeled recombinant YFV E protein (FIG. 5A). YFV E-specific swIg⁺ MBCs emerged in both donors by Days 14-28, peaked between Days 90 and 180, and slowly declined between Days 180 and 360 (FIG. 5B).

Between 100-400 YFV E-reactive B cells were sorted from both donors at each sampling time point. Naïve B cell-derived non-binding mAbs were captured via the sorting strategy employed but excluded from subsequent analyses. Analysis of the B cell surface markers expressed on the single-cell sorted, YFV E-reactive B cells revealed that the MBC response to YFV E was highly heterogenous at all time points (data not shown). At the earliest sampling time point (day 14), activated naïve B cells and IgM+CD27+ MBCs dominated the response in both donors, but these B cell populations waned rapidly over time. By day 90, less than 15% of the YFV E-specific response was comprised of IgM+CD27+ MBCs, and by day 360, only about 5% of YFV E-specific B cells belonged to this MBC population (FIG. 8B). In contrast, the swIg+ MBC population—which was comprised of both CD27+ and CD27− B cells—expanded between day 14 and day 90 and then remained stable throughout the course of the study. The MBC response observed following YFV-17D vaccination was also observed following natural infection with PUUV (data not shown).

SHM loads, apparent binding affinities (K_D^Apps), and neutralization potencies of the YFV E-specific mAbs were tracked at each sampling time point. In both donors, the median level of SHM was low at day 14—with over 50% of Abs lacking somatic mutations—and increased gradually over a 6-9-month time period, plateauing in both donors by 9 months post-vaccination, with a median of 9 and 7 nucleotide substitutions in V_H for donor 8 and 9, respectively (data not shown). Binding studies with a recombinant YFV E protein showed that the K_D^Apps of the MBC-derived mAbs were very weak at early time points and progressively improved for 6-9 months following vaccination (data not shown). On days 14 and 28 post-vaccination, the majority of YFV E-specific mAbs displayed K_D^Apps>50 nM, whereas by day 180, about 50% of the YFV E-specific mAbs displayed K_D^Apps<5 nM. In parallel with the increase in affinity, the emergence of highly potent neutralizing antibodies (IC₅₀<1 nM) were observed beginning at day 90 (data not shown). These neutralizing antibodies were derived from multiple MBC subsets, including atypical IgM+ and/or IgD+ MBCs (data not shown). Table 2 summarizes affinity and neutralization data for the isolated and characterized neutralizing mAbs.

Ongoing B cell activation was assessed by analyzing expression of CD71 and CD21 on YFV E-specific MBCs. CD71 was expressed on 75-85% YFV E-specific B cells at day 14 and remained elevated for about 6 months in both donors (data not shown). In both donors, YFV E-specific CD21^lo cells were present at high frequencies on days 14 and 28 post-vaccination, comprising about 40-80% of the YFV E-specific response, and then declined rapidly by day 90. While there was a high degree of overlap between the CD71⁺ and CD21^lo populations, with 50-80% of YFV E-specific activated B cells (defined as CD71⁺ and/or CD21^lo) displaying a CD71⁺CD21^lo phenotype at day 14, by day 28-90, the CD71⁺CD21^lo population waned to <50% of the activated B cell response in both donors and the majority of YFV E-specific activated B cells displayed either a CD71⁺CD21⁺ or CD71⁻CD21^lo phenotype and were heterogenous with regard to isotype and CD27 expression (data not shown).

Isolation and Characterization of Anti-YFV Antibodies

Approximately 152 neutralizing monoclonal antibodies were isolated and characterized. Antibody variable heavy (VH) and variable light (VL) chain genes were rescued by single-cell PCR. Tiller et al. (2008) J Immunol Methods 329, 112-124. Cognate heavy and light chain pairs were subsequently cloned and expressed as full-length IgGs in an engineered strain of Saccharomyces cerevisiae for further characterization. Bornholdt et al., (2016) Science 351, 1078-1083.

Germline gene usage of the isolated mAbs was analyzed. In both donors, mAbs utilizing the VH3-72 germline gene dominated the response at all time points (FIG. 6A). A large fraction of these mAbs also utilized one of five dominant light chain (LC) germline genes and displayed shorter-than-average heavy chain (HC) complementary determining region 3 (CDRH3) lengths, suggesting a shared mode of antigen recognition (FIG. 6B-C). The binding affinities of the mAbs utilizing VH3-72 were significantly higher than those observed for mAbs utilizing other VH germlines, despite containing similar levels of SHM (FIG. 6D-E). Table 1 summarizes germline usage and number of nucleotide substitions for isolated mAbs.

To explore the epitope coverage of the isolated mAbs, pairwise competition experiments were performed using the newly isolated mAbs and two well-characterized control mAbs, 4G2 and 5A, which recognize proximal but non-overlapping epitopes within DII of the YFV E monomer. 4G2 is a pan-flavivirus mAb that targets the FL, whereas 5A is a YFV E-specific mAb that binds to a FL-proximal epitope overlapping the proposed prM association region. Competition experiments were performed using high-throughput surface plasmon resonance (SPR) on a Carterra LSA instrument. Reactivity of the mAbs with a recombinant YFV-17D DIII protein by BLI was also evaluated. The majority of mAbs recognized one of eight distinct antigenic sites, which were defined based on reactivity with DIII and competition with 4G2, 5A, and three of the newly isolated mAbs (ADI-49147, ADI-44112, and ADI-45107) (FIG. 7A). A subset of mAbs competed with both 5A and ADI-45107, suggesting that these two antigenic sites are in close proximity. A small subset of mAbs (6 of 772) recognized epitopes within DIII. Five of the DIII-directed mAbs cross-competed, whereas the sixth, ADI-48945, may recognize a unique epitope. Over half of the mAbs from both donors competed with 4G2 and/or 5A, suggesting that the majority of the YFV E-specific response is mediated by Abs that target epitopes within or proximal to the FL on DII (FIG. 7A). Nearly all the mAbs that utilized the VH3-72 germline gene competed with 4G2 (FIG. 7B). Accordingly, analysis of the sequence features of the mAbs clustered by competition group revealed that over half of the mAbs that competed with 4G2 utilized the VH3-72 germline gene (FIG. 7C). The 4G2 competitor mAbs utilizing VH3-72 showed significantly higher affinities compared to those utilizing other V_H germline genes (FIG. 7D). Although the proportion of mAbs targeting each antigenic site did not change dramatically over time, suppression of 4G2/5A competitor mAbs was observed at later timepoints in donor 8 (days 270 and 360). Furthermore, in both donors, mAbs that competed with both 5A and ADI-45107 did not emerge until day 28-90. Results suggest that the vast majority of the YFV E-specific response is directed against epitopes within or proximal to the FL on domain II, and there are only minor shifts in Ab immunodominance hierarchy during the maturation of the B cell response to YFV-17D.

Highly Potent Neutralizing Antibodies Recognize FL Proximal Epitopes

The relationship between antigenic site and neutralization potency was investigated. Over 90% of the mAbs that competed either with 5A only or both 5A and ADI-45107 showed neutralizing activity (FIG. 8A). The majority (78%) of highly potent neutralizing antibodies (IC₅₀<1 nM) in the panel belonged to these two competition groups (FIG. 8B-8C). Table 2 provides bin data for these antibodies. Analysis of the sequence features of these 5A-only or 5A/ADI-45107 competitor neutralizing antibodies revealed that nearly 40% utilized VH4-4/VL1-51 germline gene pairing and did not show evidence of a convergent CDRH3 sequence, suggesting a common mode of germline-encoded antigen recognition (FIG. 8D). In line with prior studies, most of the DIII-directed mAbs also showed highly potent neutralizing activity. In contrast to the 5A competitors and DIII-directed mAbs, only a minority of the mAbs belonging to other competition groups showed neutralizing activity. For example, only 12% and 20% of mAbs that competed with 4G2 only or both 4G2 and 5A, respectively, displayed neutralization IC₅₀s<100 nM. The results demonstrate that the nAb response to YFV-17D is primarily mediated by Abs that recognize FL proximal epitopes within DII of the YFV E protein.

A Subset of mAbs Display Cross-Reactivity with E Proteins from Other Flaviviruses

The isolated mAbs were evaluated for binding reactivity to recombinant DENV-2, DENV-4, WNV, or ZIKV E proteins. In both donors, about 6% of YFV E-reactive mAbs showed cross-reactivity to at least one heterologous flavivirus E protein (FIG. 9A). The majority of these cross-reactive mAbs targeted the highly conserved FL epitope and bound to all five flavivirus E proteins with high apparent avid affinities (K_D^Apps<10 nM) (FIG. 9B-9C). Correspondingly, the small subset of mAbs that bound to epitopes outside of the FL generally displayed more limited cross-reactivity profiles and lower K_D^Apps (FIG. 9C). Only 6 out of 50 cross-reactive mAbs showed neutralizing activity against YFV-17D, and only a single mAb, the DIII binder ADI-48905, showed detectable albeit weak neutralizing activity against ZIKV (IC₅₀˜100 nM). None of the mAbs had measurable neutralization activity against the West Nile virus or Japanese encephalitis virus reporter viral particles. YFV-17D vaccination thus appears to induce a subset of Abs that display broad flavivirus binding activity, the majority of which target the highly conserved FL and show little to no cross-neutralizing activity.

Materials and Methods

Study Design

Study subjects aged 30 and 31 years of age were vaccinated with the YFV-17D Stamaril vaccine. Heparinized blood (50-100 cc) was obtained from subjects before vaccination and on days 10, 14, 28, 90, 180, 270, and 360 following vaccination. Samples were processed in the Immune Monitoring and Flow Cytometry core laboratory at the Geisel School of Medicine at Dartmouth to obtain plasma and to isolate peripheral blood-derived B cells. Isolated cells and plasma were stored frozen in aliquots at −80° C.

Cells: Huh 7.5.1 cells (received from Dr. Jan Carette; originally from Dr. Frank Chisari) were passaged every 3 to 4 days using 0.05% Trypsin/EDTA solution (Gibco) and maintained in Dulbecco's Modified Eagle Medium (DMEM high glucose, Gibco) supplemented with 10% heat-inactivated fetal bovine serum (FBS, Atlanta Biologicals), 1% Penicillin/Streptomycin (P/S, Gibco), 1% Gluta-MAX (Gibco) and 25 mM HEPES (Gibco). Vero African grivet monkey kidney cells (obtained from ATCC) were passaged every 3 to 4 days using 0.05% Trypsin/EDTA solution (Gibco) and maintained in Dulbecco's Modified Eagle Medium (DMEM high glucose, Gibco) supplemented with 2% heat-inactivated fetal bovine serum (FBS, Atlanta Biologicals), 1% Penicillin/Streptomycin (P/S, Gibco), 1% Gluta-MAX (Gibco) and 25 mM HEPES (Gibco).

Yellow Fever virus 17D generation: YFV-17D was obtained from BEI Resources (cat #NR-115). 15 cm plates with Huh 7.5.1 in a confluency of 80% were infected with 90 μL of passage 2 stock of YFV-17D supernatant in 3 mL of infection media (DMEM low glucose (Gibco), 7% FBS, 1% Pen-Strep, 1% Gluta-MAX (Gibco), 25 mM HEPES (Gibco)) for 1 hour at 37C and 5% CO2. After 3 days the supernatant was harvested and centrifuged twice at 4,000 rpm for 15 min at 4° C. to remove cell debris. The YFV-17D viral stock for neutralization assays was generated by ultracentrifugation of the pre-cleared supernatant at 28,000 rpm using a SW28 rotor (Beckman Coulter) in a Beckman Coulter Optima LE-80K ultracentrifuge for 4 hours through a 2 mL 30% (v/v) D-sucrose/PBS cushion. The pellet was allowed to resuspend overnight on ice in 300 ul PBS and afterwards aliquoted and frozen at −80 C.

Zika virus generation: The Zika virus strain MR 766 was obtained from ATCC (ATCC® VR-84™). For neutralization assay 15 cm plates with Vero cells in a confluency of 80% were infected with 90 μL of passage 1 stock of Zika supernatant in 3 mL of infection media (DMEM low glucose (Gibco), 2% FBS, 1% Pen-Strep, 1% Gluta-MAX (Gibco), 25 mM HEPES (Gibco)) for 1 hour at 37C and 5% CO2. After 3 days the supernatant was harvested and centrifuged twice at 4,000 rpm for 15 min at 4° C. to remove cell debris.

Antigens and Antibodies

Production of recombinant YFV antigens: The coding region for the entire prM and soluble E (sE) region of the YFV Asibi Strain (Uniprot ID: Q6DV88, residues 122-678 of the genome polyprotein) was cloned into pMT-puro, an insect expression vector encoding a C-terminal double strep tag. Expression construct design was based on previously published structures of flavivirus antigens61, 62, 63. The YFV prM/E construct was used to generate an inducible, stable Drosophila S2 line. Protein expression was induced with addition of copper sulfate and allowed to proceed for 5-7 days. Recombinant protein was affinity-purified from the culture supernatant with a StrepTrap HP column (GE Healthcare). An additional purification step was carried out using size-exclusion chromatography step using an S200Increase column (GE Healthcare). The final protein preparations were stored in phosphate-buffered saline pH 7.4 supplemented with an additional 150 mM NaCl. Small aliquots were stored at −70° C. until use. The additional flavivirus antigens used int his study—DENV-2 E, DENV-4 E, WNV E and ZIKV E were expressed and purified essentially as described for YFV sE.

Flavivirus NS1 protein antigens: The NS1 proteins from dengue virus (serotypes 1-4), JEV, TBEV, WNV, YFV were purchased from Native Antigen Company (Cat #FLAVX4-NS1-100 and DENVX4-NS1-100) and the ZIKV NS1 was purchased from Meridian Life Science (Cat #R01636). The positive control antibodies reactive to the above NS1 proteins were obtained from Native Antigen Company: anti-DENV NS1 (Cat #AbDENVNS1-DA034), anti-ZIKV NS1 antibody (Cat #AbZIKVNS1-B4-100). The anti-YFV NS1 protein antibody was purchased from Meridain Life Sciences (Cat #C01906M). The anti-WNV NS1 antibody (Cat #HM484-X0632) and anti-TBEV NS1 antibody (Cat #HM477-X1462) were purchased from East Coast Bio. Flavivirus cross-reactive serum was used to detect the JEV NS1 protein.

YFV-17D DIII protein: The DIII region (aa 293-397) of YFV-17D E protein (Uniprot ID: P03314) was produced in Drosophila S2 cells using a modified pT350 vector (Felix Rey, Institut Pasteur, France). Protein expression was induced by CdCl2 and the supernatant was harvested 5-7 days post-induction. Recombinant protein was purified using a Strep-Tactin column (IBA) and size-exclusion chromatography using a S200Increase column (GE Healthcare) and 10 mMTris pH8/150 mM NaCl buffer.

Single B-Cell Sorting

For plasmablast sorting, PBMCs were stained using anti-human CD38 (PE), CD27 (BV421), CD20 (PE-Cy7), CD3 (PerCP-Cy5.5), CD8 (PerCP-Cy5.5), CD14 (PerCP-Cy5.5) and CD16 (PerCP-Cy5.5). Plasmablasts were defined as CD19+CD3−CD20−/loCD27highCD38high cells. For MBC sorting, B cells were purified using a MACS B cell isolation kit (Miltenyi Biotec; cat #130-091-151) and subsequently stained using anti-human CD19 (PE-Cy7), CD20 (PE-Cy7), CD3 (PerCP-Cy5.5), CD8 (PerCP-Cy5.5), CD14 (PerCP-Cy5.5), CD16 (PerCP-Cy5.5), IgD (BV421), IgM (AF-488), CD27 (BV510), CD21 (BV605), CD71 (APC-Cy7 and a mixture of dual-labeled (APC and PE) YFV E tetramers (25 nM each). Tetramers were prepared fresh for each experiment, and B cells that showed reactivity to the YFV E tetramers were single cell sorted. Single cells were sorted using a BD FACS Aria II (BD Biosciences) into 96-well PCR plates (BioRAD) containing 20 uL/well of lysis buffer [5 uL of 5× first strand cDNA buffer (Invitrogen), 0.625 uL of NP-40 (New England Biolabs), 0.25 uL RNaseOUT (Invitrogen), 1.25 uL dithiothreitol (Invitrogen), and 12.6 uL dH2O]. Plates were immediately stored at −80° C. Flow cytometry data were analyzed using FlowJo software.

Amplification and Cloning of Antibody Variable Genes

Antibody variable genes (IgH, IgK, and IgL) were amplified by reverse transcription PCR and nested PCRs using cocktails of IgG- and IgM-specific primers, as described previously (Tiller et al, J Immunol 2008). The primers used in the second round of PCR contained 40 base pairs of 5′ and 3′ homology to the digested expression vectors, which allowed for cloning by homologous recombination into S. cerevisiae. The lithium acetate method for chemical transformation was used to clone the PCR products into S. cerevisiae (Gietz and Schiestl, Nat Protoc 2007). 10 uL of unpurified heavy chain and light chain PCR product and 200 ng of the digested expression vectors were used per transformation reaction. Following transformation, individual yeast colonies were picked for sequencing and characterization.

IgGs were expressed in S. cerevisiae cultures grown in 24-well plates, as described previously (Bornholdt et al, Science 2016b). After 6 days, the cultures were harvested by centrifugation and IgGs were purified by protein A-affinity chromatography. The bound antibodies were eluted with 200 mM acetic acid/50 mM NaCl (pH 3.5) into ⅛th volume 2 M Hepes (pH 8.0), and buffer-exchanged into PBS (pH 7.0).

The two YFV E-reactive control mAbs, 5A and 4G2, were produced in the human IgG1 constant region. The publicly available variable region sequences of the two control antibodies, 4G2 and 5A, were synthesized as gBlock fragments (IDT) with homologous overhangs for recombinational cloning into S. cerevisiae. Subsequent production was carried out as described above.

Fab fragments were generated by digesting the IgGs with papain for 2h at 30° C. The digestion was terminated by the addition of iodoacetamide, and the Fab and Fc mixtures were passed over Protein A agarose to remove Fc fragments and undigested IgG. The flowthrough of the Protein A resin was then passed over CaptureSelect™ IgG-CH1 affinity resin (ThermoFischer Scientific), and eluted with 200 mM acetic acid/50 mM NaCl pH 3.5 into ⅛th volume 2M Hepes pH 8.0. Fab fragments then were buffer-exchanged into PBS pH 7.0.

Kinetics of Binding Measurements

Surface Plasmon Resonance Kinetic Measurements (SPR) of IgG binding: A Biacore 8K system, docked with a CAP sensor chip, sample compartment was set to 10° C., flow cell temperature to 25° C., and the data collection rate to 10 Hz. HBS-EP+ (10 mM HEPES pH 7.3, 150 mM NaCl, 3 mM EDTA, 0.05% Surfactant P20) was used as the running buffer. In each cycle, biotin CAPture reagent (GE Healthcare) diluted 1:20 in running buffer was injected over flow cells 1 and 2 for 600 s, at a flow rate of 5 uL/min, followed by a 900 s capture (1 uL/min) of biotinylated YFV E antigen (25 nM in HBS-EP+) over flow cell 2 to reach a minimum capture level of 400 RU. The antibodies (36-288 nM in HBS-EP+) were then injected over flow cells 1 and 2 for 300 s (30 uL/min), the dissociation monitored for 300 s (30 uL/min), and the surface regenerated at the oligonucleotide level with 6M Guanidine-HCl in 0.25 M NaOH for 120 s (10 uL/min). A minimum of two blank (HBS-EP+) injections also were run under identical conditions as described above and used to assess and subtract system artifacts. The data were aligned, double referenced, and fit to bivalent analyte binding model using Biacore 8K Evaluation Software, version 1.0.

Bio-Layer Interferometry Kinetic Measurements (BLI): For monovalent apparent K_D determination, IgG binding to recombinant YFV E antigen was measured by biolayer interferometry (BLI) using a ForteBio Octet HTX instrument (Molecular Devices). The IgGs were captured (1.5 nm) to anti-human IgG capture (AHC) biosensors Molecular Devices) and allowed to stand in PBSF (PBS with 0.1% w/v BSA) for a minimum of 30 min. After a short (60 s) baseline step in PBSF, the IgG-loaded biosensor tips were exposed (180 s, 1000 rpm of orbital shaking) to YFV E antigen (100 nM in PBSF) and then dipped (180 s, 1000 rpm of orbital shaking) into PBSF to measure any dissociation of the antigen from the biosensor tip surface. Data for which binding responses were >0.1 nm were aligned, inter-step corrected (to the association step) and fit to a 1:1 binding model using the ForteBio Data Analysis Software, version 11.1.

For bivalent apparent KD determination, IgG binding to recombinant biotinylated YFV E antigen was measured by biolayer interferometry (BLI) using a ForteBio Octet HTX instrument (Molecular Devices).

High Throughput Antibody Epitope Assignment

Bio-Layer Interferometry (BLI) Epitope Binning: For epitope binning, control antibodies A5 and 4G2 (produced as human IgG1 chimeras) were captured on anti-human IgG capture biosensors (0.9 nm) (Molecular Devices) and the biosensors were then blocked by exposing them to adalimumab (0.5 mg/mL; 20 min, 350 rpm of orbital shaking). After a short (60 s) baseline step in PBSF, a cross-interaction check was performed between the sample IgGs and the loaded biosensors (180 s, 1000 rpm of orbital shaking). No cross-interaction was observed for this panel of IgGs. The loaded biosensors were then subjected to a second short (60 s) baseline step in PBSF, followed by an association step in 100 nM recombinant YFV E monomer (180 s, 1000 rpm of orbital shaking). Finally, the binning step was performed in 100 nM sample IgGs in PBS with 0.1% BSA (PBSF) (180 s, 1000 rpm of orbital shaking). Data were analyzed using the FortéBio Data Analysis Software, version 11.1. Sample IgGs with a binning response lower than 0.1 nm were determined to compete with the control antibody. Sample IgGs with a binning response greater than 0.1 nm were determined to be non-competitors to the control antibody.

High-Throughput Epitope Binning Using Carterra LSA (SPR)

Binding kinetics and affinities. The kinetic rate and affinity constants for Yellow Fever antigen (supplied by Adimab as purified recombinant monomer, 1\4W of 45 kDa) binding to a library of 770+ ADI mAbs (supplied as purified human IgG) were determined at a temperature of 25° C. in a “Capture Kinetics” assay format using Carterra's high throughput surface plasmon resonance (SPR) biosensor platform equipped with HC-30M chip type. To prepare the surfaces for this experiment, the chip was coated as a “lawn” with a capture reagent, namely goat anti-human-IgG Fc polyclonal cross-adsorbed to serum proteins from multiple other species (Southern Biotech, cat #2014-01) using standard amine coupling in a run buffer of 10 mM Hepes pH 7.4, 150 mM NaCl, 3 mM EDTA, 0.05% Tween20 (HBSET). Briefly, this involved priming the single flow cell (SFC) with HBSET run buffer, injecting a freshly prepared activation solution of 1:1:1 v/v/v 0.1 M N-hydroxysulfosuccinimide (Sulfo-NHS, Pierce)+0.4 M 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride) (EDC, Pierce)+0.1 M MES pH 5.5 (Carterra) for 10 min, coupling 50 μg/ml goat anti-human-IgG Fc diluted into 10 mM sodium acetate pH 4.3 for 15 min, and quenching excess reactive esters with 1 M ethanolamine pH 8.5 for 7 min. This resulted in mean final coupled levels of 6256 RU±4% variance (as judged by the 384 reaction spots). The 96-channel printhead (96PH) was then primed in run buffer and used to capture the ADI mAbs as ligands, which were diluted to 2 μg/ml in run buffer and batch-printed 96 at a time onto discrete spots. Four serial docks of the 96PH were used to address all 4 print block locations, thus generating a 384-ligand array. The 96PH was returned to water for cleaning and the SFC was docked over the printed array and primed with the assay run buffer of HBSET+0.5 g/l BSA. Analyte samples of Yellow Fever Monomer antigen were prepared as an 8 membered 4 fold dilution series spanning nominal concentrations of 0.02-367 nM and injected in the SFC in ascending concentration after several buffer (blank) injections. Association and dissociation times were 5 min and 20 min respectively. Data were analyzed in Carterra's Kinetic Software as follows. The binding data on the reaction spots were double referenced by subtracting the responses from local reference spots (representing naked capture reagent) and then subtracting the responses from a buffer blank analyte 66. Double-referenced data were fit globally to a simple Langmuir model allowing each spot its own association rate constant (ka), dissociation rate constant (kd), and Rmax value. The equilibrium dissociation (affinity) constant (KD) was computed from the ratio of the kinetic rate constants, KD=kd/ka).

Epitope binning experiments: Carterra's LSA was used to perform epitope binning assays in a classical sandwich assay format67 using 6 benchmark mAbs (ADI-49582, ADI-44112, ADI-45107, ADI-49147, 4G2, and 5A) as analyte to probe the epitope diversity of the 770+ ADI library as ligands. An HCX-30M (pre-activated) chip type was used and experiments were performed at 25° C. The SFC and 96PH were primed in run buffer of 25 mM Mes pH5.5+0.01% Tween20. The ADI mAbs were diluted to 2 μg/ml in 10 mM sodium acetate pH 4.5 (coupling buffer) and coupled via the 96PH using 7 min contact time at each print block location. After 4 serial docks of the 96PH to build up a 384-ligand array, the SFC was docked over the entire surface to quench excess reactive esters by injecting ethanolamine pH8.5 for 7 min. Final coupled levels of each mAb ranged from 1000-4000 RU per spot. The 96PH was returned to water for cleaning and the SFC was primed in an assay run buffer of HBSET+0.5 g/l BSA. Each binning cycle involved a co-inject style of sample delivery whereby the antigen (50 nM Yellow Fever Monomer) and antibody analyte (20 ug/ml mAb or buffer) samples were injected back-to-back, with minimal dissociation time between them over the 384-ligand array. Typical association times were 3 or 5 min and surfaces were regenerated with 75 mM phosphoric acid after each binning cycle. The binding data were analyzed in Carterra's Epitope Software.
