Definitions

  • TF Tissue factor
  • FVIIa serine protease factor Vila
  • the TF/FVIIa complex catalyzes conversion of the inactive protease factor X (FX) into the active protease factor Xa (FXa).
  • FXa and its co-factor FVa form the prothrombinase complex, which generates thrombin from prothrombin.
  • Thrombin converts soluble fibrinogen into insoluble strands of fibrin and catalyzes many other coagulation-related processes.
  • TF is over-expressed on multiple types of solid tumors.
  • TF/FVIIa signaling can support angiogenesis, tumor progression, and metastasis.
  • Increased TF expression can also induce inflammation and/or angiogenesis in many other diseases, including wet age- related macular degeneration (AMD) and diabetic retinopathy.
  • AMD wet age- related macular degeneration

BACKGROUND
[0003] Blood coagulation involves a complex set of processes that result in blood clotting. Tissue factor (TF) plays an important role in these coagulation processes. TF is a cell surface receptor for the serine protease factor Vila (FVIIa). The TF/FVIIa complex catalyzes conversion of the inactive protease factor X (FX) into the active protease factor Xa (FXa). FXa and its co-factor FVa form the prothrombinase complex, which generates thrombin from prothrombin. Thrombin converts soluble fibrinogen into insoluble strands of fibrin and catalyzes many other coagulation-related processes.
[0004] TF is over-expressed on multiple types of solid tumors. In cancer, TF/FVIIa signaling can support angiogenesis, tumor progression, and metastasis. Increased TF expression can also induce inflammation and/or angiogenesis in many other diseases, including wet age- related macular degeneration (AMD) and diabetic retinopathy.

In certain embodiments, the term“about” indicates the designated value ± 10%, ± 5%, or ± 1%. In certain embodiments, where applicable, the term“about” indicates the designated value(s) ± one standard deviation of that value(s).
[00290] The terms“Tissue Factor,”“TF,”“platelet tissue factor,”“factor III,”
“thromboplastin,” and“CD 142” are used interchangeably herein to refer to TF, or any variants ( e.g ., splice variants and allelic variants), isoforms, and species homologs of TF that are naturally expressed by cells, or that are expressed by cells transfected with a TF gene. In some aspects, the TF protein is a TF protein naturally expressed by a primate (e.g., a monkey or a human), a rodent (e.g, a mouse or a rat), a dog, a camel, a cat, a cow, a goat, a horse, a pig or a sheep. In some aspects, the TF protein is human TF (hTF; SEQ ID NO:809). In some aspects, the TF protein is cynomolgus TF (cTF; SEQ ID NO:8l3). In some aspects, the TF protein is mouse TF (mTF; SEQ ID NO:8l7). In some aspects, the TF protein is pig TF (pTF; SEQ ID NO:824). TF is a cell surface receptor for the serine protease factor Vila. It is often times constitutively expressed by certain cells surrounding blood vessels and in some disease settings.
[00291] The term“antibody-drug conjugate” or“ADC” refers to a conjugate comprising an antibody conjugated to one or more cytotoxic agents, optionally through one or more linkers. The term“anti-TF antibody-drug conjugate” or“anti-TF ADC” refers to a conjugate comprising an anti-TF antibody conjugated to one or more cytotoxic agents, optionally through one or more linkers.
[00292] The term“cytotoxic agent,” as used herein, refers to a substance that inhibits or prevents a cellular function and/or causes cell death or destruction. The cytotoxic agent can be an anti-angiogenic agent, a pro-apoptotic agent, an anti-mitotic agent, an anti-kinase agent, an alkylating agent, a hormone, a hormone agonist, a hormone antagonist, a chemokine, a drug, a prodrug, a toxin, an enzyme, an antimetabolite, an antibiotic, an alkaloid, or a radioactive isotope. Exemplary cytotoxic agents include calicheamycin, camptothecin, carboplatin, irinotecan, SN-38, carboplatin, camptothecan, cyclophosphamide, cytarabine, dacarbazine, docetaxel, dactinomycin, daunorubicin, doxorubicin, doxorubicin, etoposide, idarubicin, topotecan, vinca alkaloid, maytansinoid, maytansinoid analog,
pyrrolobenzodiazepine, taxoid, duocarmycin, dolastatin, auristatin, and derivatives thereof.
[00293] A“linker” refers to a molecule that connects one composition to another, e.g., an antibody to an agent. Linkers described herein can conjugate an antibody to a cytotoxic agent. Exemplary linkers include a labile linker, an acid labile linker, a photolabile linker, a charged linker, a disulfide-containing linker, a peptidase-sensitive linker, a□-glucuronide-linker, a dimethyl linker, a thio-ether linker, and a hydrophilic linker. A linker can be cleavable or non-cleavable.
[00294] The term“immunoglobulin” refers to a class of structurally related proteins generally comprising two pairs of polypeptide chains: one pair of light (L) chains and one pair of heavy (H) chains. In an“intact immunoglobulin,” all four of these chains are interconnected by disulfide bonds. The structure of immunoglobulins has been well characterized. See, e.g., Paul, Fundamental Immunology 7th ed., Ch. 5 (2013) Lippincott Williams & Wilkins, Philadelphia, PA. Briefly, each heavy chain typically comprises a heavy chain variable region (VH) and a heavy chain constant region (CH). The heavy chain constant region typically comprises three domains, abbreviated CHI, Cm, and Cm. Each light chain typically comprises a light chain variable region (VL) and a light chain constant region. The light chain constant region typically comprises one domain, abbreviated CL.
[00295] The term“antibody” is used herein in its broadest sense and includes certain types of immunoglobulin molecules comprising one or more antigen-binding domains that specifically bind to an antigen or epitope. An antibody specifically includes intact antibodies (e.g, intact immunoglobulins), antibody fragments, and multi-specific antibodies.
[00296] The term“alternative scaffold” refers to a molecule in which one or more regions may be diversified to produce one or more antigen-binding domains that specifically bind to an antigen or epitope. In some embodiments, the antigen-binding domain binds the antigen or epitope with specificity and affinity similar to that of an antibody. Exemplary alternative scaffolds include those derived from fibronectin (e.g, AdnectinsTM), the b-sandwich (e.g, iMab), lipocalin (e.g, Anticalins®), EETI-IEAGRP, BPTI/LACI-D1/ITI-D2 (e.g, Kunitz domains), thioredoxin peptide aptamers, protein A (e.g, Affibody®), ankyrin repeats (e.g, DARPins), gamma-B-crystallin/ubiquitin (e.g, Affilins), CTLD3 (e.g, Tetranectins), Fynomers, and (LDLR-A module) (e.g, Avimers). Additional information on alternative scaffolds is provided in Binz et ah, Nat. Biotechnol, 2005 23: 1257-1268; Skerra, Current Opin. in Biotech., 2007 18:295-304; and Silacci et ah, J. Biol. Chem., 2014, 289: 14392- 14398; each of which is incorporated by reference in its entirety.
[00297] The term“antigen-binding domain” means the portion of an antibody that is capable of specifically binding to an antigen or epitope. One example of an antigen-binding domain is an antigen-binding domain formed by a VH -VL dimer of an antibody. Another example of an antigen-binding domain is an antigen-binding domain formed by
diversification of certain loops from the tenth fibronectin type III domain of an Adnectin. Antigen-binding domains can be found in various contexts including antibodies and chimeric antigen receptors (CARs), for example CARs derived from antibodies or antibody fragments such as scFvs.
[00298] The terms“full length antibody,”“intact antibody,” and“whole antibody” are used herein interchangeably to refer to an antibody having a structure substantially similar to a naturally occurring antibody structure and having heavy chains that comprise an Fc region. For example, when used to refer to an IgG molecule, a“full length antibody” is an antibody that comprises two heavy chains and two light chains.
[00299] The term“Fc region” means the C-terminal region of an immunoglobulin heavy chain that, in naturally occurring antibodies, interacts with Fc receptors and certain proteins of the complement system. The structures of the Fc regions of various immunoglobulins, and the glycosylation sites contained therein, are known in the art. See Schroeder and Cavacini, ./. Allergy Clin. Immunol ., 2010, l25:S4l-52, incorporated by reference in its entirety. The Fc region may be a naturally occurring Fc region, or an Fc region modified as described in the art or elsewhere in this disclosure.
[00300] The VH and VL regions may be further subdivided into regions of hypervariability (“hypervariable regions (HVRs);” also called“complementarity determining regions” (CDRs)) interspersed with regions that are more conserved. The more conserved regions are called framework regions (FRs). Each VH and VL generally comprises three CDRs and four FRs, arranged in the following order (from N-terminus to C-terminus): FR1 - CDR1 - FR2 - CDR2 - FR3 - CDR3 - FR4. The CDRs are involved in antigen binding, and influence antigen specificity and binding affinity of the antibody. See Rabat et al., Sequences of Proteins of Immunological Interest 5th ed. (1991) Public Health Service, National Institutes of Health, Bethesda, MD, incorporated by reference in its entirety.
[00301] A“Complementary Determining Region (CDR)” refers to one of three
hypervariable regions (Hl, H2 or H3) within the non-framework region of the
immunoglobulin (Ig or antibody) VH b-sheet framework, or one of three hypervariable regions (Ll, L2 or L3) within the non-framework region of the antibody VL b-sheet framework. CDRs are variable region sequences interspersed within the framework region sequences. CDRs are well recognized in the art and have been defined by, for example, Rabat as the regions of most hypervariability within the antibody variable (V) domains. See Rabat et al., J Biol Chem , 1977, 252:6609-6616 and Rabat, Adv Protein Chem , 1978, 32: 1-75, each of which is incorporated by reference in its entirety. CDRs have also been defined
structurally by Chothia as those residues that are not part of the conserved b-sheet framework, and thus are able to adapt different conformations. See Chothia and Lesk, JMol Biol , 1987, 196:901-917, incorporated by reference in its entirety. Both the Kabat and Chothia nomenclatures are well known in the art. AbM, Contact and IMGT also defined CDRs. CDR positions within a canonical antibody variable domain have been determined by comparison of numerous structures. See Morea et ah, Methods , 2000, 20:267-279 and Al- Lazikani et ah, JMol Biol , 1997, 273:927-48, each of which is incorporated by reference in its entirety. Because the number of residues within a hypervariable region varies in different antibodies, additional residues relative to the canonical positions are conventionally numbered with a, b, c and so forth next to the residue number in the canonical variable domain numbering scheme (Al-Lazikani et ah, supra). Such terminology is well known to those skilled in the art.
[00302] A number of hypervariable region delineations are in use and are included herein. The Kabat CDRs are based on sequence variability and are the most commonly used. See Kabat et al. (1992) Sequences of Proteins of Immunological Interest , DIANE Publishing: 2719, incorporated by reference in its entirety. Chothia refers instead to the location of the structural loops (Chothia and Lesk, supra). The AbM hypervariable regions represent a compromise between the Kabat CDRs and Chothia structural loops, and are used by Oxford Molecular's AbM antibody modeling software. The Contact hypervariable regions are based on an analysis of the available complex crystal structures. The residues from each of these hypervariable regions are noted in Table 1.
[00303] More recently, a universal numbering system ImMunoGeneTics (IMGT)
Information SystemTM has been developed and widely adopted. See Lefranc et al., Dev Comp Immunol , 2003, 27:55-77, incorporated by reference in its entirety. IMGT is an integrated information system specializing in immunoglobulins (IG), T cell receptors (TR) and major histocompatibility complex (MHC) of human and other vertebrates. The IMGT CDRs are referred to in terms of both the amino acid sequence and the location within the light or heavy chain. As the "location" of the CDRs within the structure of the
immunoglobulin variable domain is conserved between species and present in structures called loops, by using numbering systems that align variable domain sequences according to structural features, CDR and framework residues are readily identified. Correspondence between the Kabat, Chothia and IMGT numbering is also well known in the art (Lefranc et al., supra). An Exemplary system, shown herein, combines Kabat and Chothia CDR definitions. Table 1
Figure imgf000081_0001
[00304] The light chain from any vertebrate species can be assigned to one of two types, called kappa (K) and lambda (l), based on the sequence of its constant domain.
[00305] The heavy chain from any vertebrate species can be assigned to one of five different classes (or isotypes): IgA, IgD, IgE, IgG, and IgM. These classes are also designated a, d, e, g, and m, respectively. The IgG and IgA classes are further divided into subclasses on the basis of differences in sequence and function. Humans express the following subclasses: IgGl, IgG2, IgG3, IgG4, IgAl, and IgA2.
[00306] The term "constant region" or "constant domain" refers to a carboxy terminal portion of the light and heavy chain which is not directly involved in binding of the antibody to antigen but exhibits various effector function, such as interaction with the Fc receptor. The terms refer to the portion of an immunoglobulin molecule having a more conserved amino acid sequence relative to the other portion of the immunoglobulin, the variable domain, which contains the antigen-binding site. The constant domain contains the CHI, Cm and Cm domains of the heavy chain and the CL domain of the light chain.
[00307] The“EU numbering scheme” is generally used when referring to a residue in an antibody heavy chain constant region ( e.g ., as reported in Kabat et al., supra). ETnless stated otherwise, the EEG numbering scheme is used to refer to residues in antibody heavy chain constant regions described herein.
[00308] An“antibody fragment” comprises a portion of an intact antibody, such as the antigen-binding or variable region of an intact antibody. Antibody fragments include, for example, Fv fragments, Fab fragments, F(ab’)2 fragments, Fab’ fragments, scFv (sFv) fragments, and scFv-Fc fragments.
[00309] “Fv” fragments comprise a non-covalently-linked dimer of one heavy chain variable domain and one light chain variable domain. [00310] “Fab” fragments comprise, in addition to the heavy and light chain variable domains, the constant domain of the light chain and the first constant domain (Cm) of the heavy chain. Fab fragments may be generated, for example, by recombinant methods or by papain digestion of a full-length antibody.
[00311] “F(ab’)2” fragments contain two Fab’ fragments joined, near the hinge region, by disulfide bonds. F(ab’)2 fragments may be generated, for example, by recombinant methods or by pepsin digestion of an intact antibody. The F(ab’) fragments can be dissociated, for example, by treatment with B-mercaptoethanol.
[00312] “Single-chain Fv” or“sFv” or“scFv” antibody fragments comprise a VH domain and a VL domain in a single polypeptide chain. The VH and VL are generally linked by a peptide linker. See Pliickthun A. (1994). Any suitable linker may be used. In some embodiments, the linker is a (GGGGS)n(SEQ ID NO:823). In some embodiments, n = 1, 2,
3, 4, 5, or 6. See Antibodies from Escherichia coli. In Rosenberg M. & Moore G.P. (Eds.), The Pharmacology of Monoclonal Antibodies vol. 113 (pp. 269-315). Springer-Verlag, New York, incorporated by reference in its entirety.
[00313] “ scFv-Fc” fragments comprise an scFv attached to an Fc domain. For example, an
Fc domain may be attached to the C-terminal of the scFv. The Fc domain may follow the VH or VL, depending on the orientation of the variable domains in the scFv (i.e., VH -VL or VL - VH). Any suitable Fc domain known in the art or described herein may be used.
[00314] The term“single domain antibody” refers to a molecule in which one variable domain of an antibody specifically binds to an antigen without the presence of the other variable domain. Single domain antibodies, and fragments thereof, are described in Arabi Ghahroudi et ak, FEBS Letters , 1998, 414:521-526 and Muyldermans et ah, Trends in Biochem. Sci., 2001, 26:230-245, each of which is incorporated by reference in its entirety. Single domain antibodies are also known as sdAbs or nanobodies.
[00315] A“multispecific antibody” is an antibody that comprises two or more different antigen-binding domains that collectively specifically bind two or more different epitopes. The two or more different epitopes may be epitopes on the same antigen ( e.g ., a single TF molecule expressed by a cell) or on different antigens (e.g., a TF molecule and a non-TF molecule). In some aspects, a multi-specific antibody binds two different epitopes (i.e., a “bispecific antibody”). In some aspects, a multi-specific antibody binds three different epitopes (i.e., a“trispecific antibody”). In some aspects, a multi-specific antibody binds four different epitopes (i.e., a“quadspecific antibody”). In some aspects, a multi-specific antibody binds five different epitopes (i.e., a“quintspecific antibody”). In some aspects, a multi- specific antibody binds 6, 7, 8, or more different epitopes. Each binding specificity may be present in any suitable valency. Examples of multispecific antibodies are provided elsewhere in this disclosure.
[00316] A“monospecific antibody” is an antibody that comprises one or more binding sites that specifically bind to a single epitope. An example of a monospecific antibody is a naturally occurring IgG molecule which, while divalent (z.e., having two antigen-binding domains), recognizes the same epitope at each of the two antigen-binding domains. The binding specificity may be present in any suitable valency.
[00317] The term“monoclonal antibody” refers to an antibody from a population of substantially homogeneous antibodies. A population of substantially homogeneous antibodies comprises antibodies that are substantially similar and that bind the same epitope(s), except for variants that may normally arise during production of the monoclonal antibody. Such variants are generally present in only minor amounts. A monoclonal antibody is typically obtained by a process that includes the selection of a single antibody from a plurality of antibodies. For example, the selection process can be the selection of a unique clone from a plurality of clones, such as a pool of hybridoma clones, phage clones, yeast clones, bacterial clones, or other recombinant DNA clones. The selected antibody can be further altered, for example, to improve affinity for the target (“affinity maturation”), to humanize the antibody, to improve its production in cell culture, and/or to reduce its immunogenicity in a subject.
[00318] The term“chimeric antibody” refers to an antibody in which a portion of the heavy and/or light chain is derived from a particular source or species, while the remainder of the heavy and/or light chain is derived from a different source or species.
[00319] “Humanized” forms of non-human antibodies are chimeric antibodies that contain minimal sequence derived from the non-human antibody. A humanized antibody is generally a human antibody (recipient antibody) in which residues from one or more CDRs are replaced by residues from one or more CDRs of a non-human antibody (donor antibody). The donor antibody can be any suitable non-human antibody, such as a mouse, rat, rabbit, chicken, or non-human primate antibody having a desired specificity, affinity, or biological effect. In some instances, selected framework region residues of the recipient antibody are replaced by the corresponding framework region residues from the donor antibody.
Humanized antibodies may also comprise residues that are not found in either the recipient antibody or the donor antibody. Such modifications may be made to further refine antibody function. For further details, see Jones et ah, Nature , 1986, 321 :522-525; Riechmann et ah, Nature , 1988, 332:323-329; and Presta, Curr. Op. Struct. Biol., 1992, 2:593-596, each of which is incorporated by reference in its entirety.
[00320] A“human antibody” is one which possesses an amino acid sequence
corresponding to that of an antibody produced by a human or a human cell, or derived from a non-human source that utilizes a human antibody repertoire or human antibody-encoding sequences ( e.g ., obtained from human sources or designed de novo). Human antibodies specifically exclude humanized antibodies.
[00321] An“isolated antibody” or“isolated nucleic acid” is an antibody or nucleic acid that has been separated and/or recovered from a component of its natural environment.
Components of the natural environment may include enzymes, hormones, and other proteinaceous or nonproteinaceous materials. In some embodiments, an isolated antibody is purified to a degree sufficient to obtain at least 15 residues of N-terminal or internal amino acid sequence, for example by use of a spinning cup sequenator. In some embodiments, an isolated antibody is purified to homogeneity by gel electrophoresis (e.g., SDS-PAGE) under reducing or nonreducing conditions, with detection by Coomassie blue or silver stain. In some embodiments, an isolated antibody may include an antibody in situ within recombinant cells, since at least one component of the antibody’s natural environment is not present. In some aspects, an isolated antibody or isolated nucleic acid is prepared by at least one purification step. In some embodiments, an isolated antibody or isolated nucleic acid is purified to at least 80%, 85%, 90%, 95%, or 99% by weight. In some embodiments, an isolated antibody or isolated nucleic acid is purified to at least 80%, 85%, 90%, 95%, or 99% by volume. In some embodiments, an isolated antibody or isolated nucleic acid is provided as a solution comprising at least 85%, 90%, 95%, 98%, 99% to 100% antibody or nucleic acid by weight. In some embodiments, an isolated antibody or isolated nucleic acid is provided as a solution comprising at least 85%, 90%, 95%, 98%, 99% to 100% antibody or nucleic acid by volume.
[00322] “Affinity” refers to the strength of the sum total of non-covalent interactions between a single binding site of a molecule (e.g, an antibody) and its binding partner (e.g, an antigen or epitope). Unless indicated otherwise, as used herein,“affinity” refers to intrinsic binding affinity, which reflects a 1 : 1 interaction between members of a binding pair (e.g, antibody and antigen or epitope). The affinity of a molecule X for its partner Y can be represented by the dissociation equilibrium constant (KD). The kinetic components that contribute to the dissociation equilibrium constant are described in more detail below.
Affinity can be measured by common methods known in the art, including those described herein, such as surface plasmon resonance (SPR) technology ( e.g ., BIACORE®) or biolayer interferometry (e.g., FORTEBIO®).
[00323] With regard to the binding of an antibody to a target molecule, the terms“bind,” “specific binding,”“specifically binds to,”“specific for,”“selectively binds,” and“selective for” a particular antigen (e.g, a polypeptide target) or an epitope on a particular antigen mean binding that is measurably different from a non-specific or non-selective interaction (e.g, with a non-target molecule). Specific binding can be measured, for example, by measuring binding to a target molecule and comparing it to binding to a non-target molecule. Specific binding can also be determined by competition with a control molecule that mimics the epitope recognized on the target molecule. In that case, specific binding is indicated if the binding of the antibody to the target molecule is competitively inhibited by the control molecule. In some aspects, the affinity of a TF antibody for a non-target molecule is less than about 50% of the affinity for TF. In some aspects, the affinity of a TF antibody for a non target molecule is less than about 40% of the affinity for TF. In some aspects, the affinity of a TF antibody for a non-target molecule is less than about 30% of the affinity for TF. In some aspects, the affinity of a TF antibody for a non-target molecule is less than about 20% of the affinity for TF. In some aspects, the affinity of a TF antibody for a non-target molecule is less than about 10% of the affinity for TF. In some aspects, the affinity of a TF antibody for a non-target molecule is less than about 1% of the affinity for TF. In some aspects, the affinity of a TF antibody for a non-target molecule is less than about 0.1% of the affinity for TF.
[00324] The term“kd” (sec-1), as used herein, refers to the dissociation rate constant of a particular antibody-antigen interaction. This value is also referred to as the k0ff value.
[00325] The term“ka” (M- 1 /sec- 1), as used herein, refers to the association rate constant of a particular antibody-antigen interaction. This value is also referred to as the k0n value.
[00326] The term“KD” (M), as used herein, refers to the dissociation equilibrium constant of a particular antibody-antigen interaction. KD = kd/ka. In some embodiments, the affinity of an antibody is described in terms of the KD for an interaction between such antibody and its antigen. For clarity, as known in the art, a smaller KD value indicates a higher affinity interaction, while a larger KD value indicates a lower affinity interaction.
[00327] The term“KA” (M-1), as used herein, refers to the association equilibrium constant of a particular antibody-antigen interaction. KA = kd.
[00328] An“affinity matured” antibody is an antibody with one or more alterations (e.g, in one or more CDRs or FRs) relative to a parent antibody (i.e., an antibody from which the altered antibody is derived or designed) that result in an improvement in the affinity of the antibody for its antigen, compared to the parent antibody which does not possess the alteration(s). In some embodiments, an affinity matured antibody has nanomolar or picomolar affinity for the target antigen. Affinity matured antibodies may be produced using a variety of methods known in the art. For example, Marks et al. ( Bio/Technology , 1992, 10:779-783, incorporated by reference in its entirety) describes affinity maturation by VH and VL domain shuffling. Random mutagenesis of CDR and/or framework residues is described by, for example, Barbas et al., Proc. Nat. Acad. Sci. U.S.A., 1994, 91 :3809-3813; Schier et al., Gene , 1995, 169: 147-155; Yelton et al., J. Immunol ., 1995, 155: 1994-2004; Jackson et al., J.
Immunol ., 1995, 154:3310-33199; and Hawkins et al, J. Mol. Biol., 1992, 226:889-896; each of which is incorporated by reference in its entirety.
[00329] “Fc effector functions” refer to those biological activities mediated by the Fc region of an antibody, which activities may vary depending on the antibody isotype.
Examples of antibody effector functions include Clq binding to activate complement dependent cytotoxicity (CDC), Fc receptor binding to activate antibody-dependent cellular cytotoxicity (ADCC), and antibody dependent cellular phagocytosis (ADCP).
[00330] When used herein in the context of two or more antibodies, the term“competes with” or“cross-competes with” indicates that the two or more antibodies compete for binding to an antigen ( e.g ., TF). In one exemplary assay, TF is coated on a surface and contacted with a first TF antibody, after which a second TF antibody is added. In another exemplary assay, first a TF antibody is coated on a surface and contacted with TF, and then a second TF antibody is added. If the presence of the first TF antibody reduces binding of the second TF antibody, in either assay, then the antibodies compete with each other. The term“competes with” also includes combinations of antibodies where one antibody reduces binding of another antibody, but where no competition is observed when the antibodies are added in the reverse order. However, in some embodiments, the first and second antibodies inhibit binding of each other, regardless of the order in which they are added. In some embodiments, one antibody reduces binding of another antibody to its antigen by at least 25%, at least 50%, at least 60%, at least 70%, at least 80%, at least 85%, at least 90%, or at least 95%. A skilled artisan can select the concentrations of the antibodies used in the competition assays based on the affinities of the antibodies for TF and the valency of the antibodies. The assays described in this definition are illustrative, and a skilled artisan can utilize any suitable assay to determine if antibodies compete with each other. Suitable assays are described, for example, in Cox et al.,“Immunoassay Methods,” in Assay Guidance Manual [Internet], Updated December 24, 2014 (www.ncbi.nlm.nih.gov/books/NBK92434/; accessed September 29, 2015); Silman et al., Cytometry , 2001, 44:30-37; and Finco et al., J. Pharm. Biomed. Anal., 2011, 54:351-358; each of which is incorporated by reference in its entirety. As provided in Example 8, antibodies of group 25 and antibodies of group 43 compete with each other for binding to human TF, while antibodies from groups 1, 29, 39, and 54 do not compete for binding to human TF with antibodies of groups 25 and 43.
[00331] As used herein, an antibody that binds specifically to a human antigen is considered to bind the same antigen of mouse origin when a KD value can be measured on a ForteBio Octet with the mouse antigen. An antibody that binds specifically to a human antigen is considered to be“cross-reactive” with the same antigen of mouse origin when the KD value for the mouse antigen is no greater than 20 times the corresponding KD value for the respective human antigen. For example, the antibody Ml 593 described in U.S Pat. Nos. 8,722,044, 8,951,525, and 8,999,333, each of which is herein incorporated by reference for all purposes, the humanized 5G9 antibody described in Ngo et al., 2007, Int J Cancer,
120(6): 1261-1267, incorporated by reference in its entirety, and chimeric ALT-836 antibody described in Hong et al, 2012, J Nucl Med, 53(11): 1748-1754, incorporated by reference in its entirety, do not bind to mouse TF. As provided in Examples 1 and 2, TF antibodies from groups 25 and 43 bind to mouse TF, e.g., the TF antibodies 25G, 25G1, 25G9, and 43D8 are cross-reactive with mouse TF.
[00332] As used herein, an antibody that binds specifically to a human antigen is considered to be“cross-reactive” with the same antigen of cynomolgus monkey origin when the KD value for the cynomolgus monkey antigen is no greater than 15 times the
corresponding KD value for the respective human antigen. As provided in Example 1, all tested antibodies from groups 1, 25, 29, 39, 43, and 54 are cross-reactive with cynomolgus monkey TF.
[00333] The term“epitope” means a portion of an antigen that is specifically bound by an antibody. Epitopes frequently include surface-accessible amino acid residues and/or sugar side chains and may have specific three dimensional structural characteristics, as well as specific charge characteristics. Conformational and non-conformational epitopes are distinguished in that the binding to the former but not the latter may be lost in the presence of denaturing solvents. An epitope may comprise amino acid residues that are directly involved in the binding, and other amino acid residues, which are not directly involved in the binding. The epitope to which an antibody binds can be determined using known techniques for epitope determination such as, for example, testing for antibody binding to TF variants with different point-mutations, or to chimeric TF variants. [00334] Percent“identity” between a polypeptide sequence and a reference sequence, is defined as the percentage of amino acid residues in the polypeptide sequence that are identical to the amino acid residues in the reference sequence, after aligning the sequences and introducing gaps, if necessary, to achieve the maximum percent sequence identity.
Alignment for purposes of determining percent amino acid sequence identity can be achieved in various ways that are within the skill in the art, for instance, using publicly available computer software such as BLAST, BLAST-2, ALIGN, MEGALIGN (DNASTAR), CLUSTALW, CLUSTAL OMEGA, or MUSCLE software. Those skilled in the art can determine appropriate parameters for aligning sequences, including any algorithms needed to achieve maximal alignment over the full length of the sequences being compared.
[00335] A“conservative substitution” or a“conservative amino acid substitution,” refers to the substitution of an amino acid with a chemically or functionally similar amino acid. Conservative substitution tables providing similar amino acids are well known in the art. By way of example, the groups of amino acids provided in Tables 2-4 are, in some
embodiments, considered conservative substitutions for one another.

Such progeny may not be completely identical in nucleic acid content to a parent cell, and may contain mutations.
[00340] The term“treating” (and variations thereof such as“treat” or“treatment”) refers to clinical intervention in an attempt to alter the natural course of a disease or condition in a subject in need thereof. Treatment can be performed both for prophylaxis and during the course of clinical pathology. Desirable effects of treatment include preventing occurrence or recurrence of disease, alleviation of symptoms, diminishment of any direct or indirect pathological consequences of the disease, preventing metastasis, decreasing the rate of disease progression, amelioration or palliation of the disease state, and remission or improved prognosis.

In some embodiments, a multispecific antibody binds two antigens. In some embodiments, a multispecific antibody binds three antigens. In some embodiments, a multispecific antibody binds four antigens. In some embodiments, a multispecific antibody binds five antigens.
[00537] In some embodiments, a multispecific antibody provided herein binds more than one epitope on a TF antigen. In some embodiments, a multispecific antibody binds two epitopes on a TF antigen. In some embodiments, a multispecific antibody binds three epitopes on a TF antigen.
[00538] Many multispecific antibody constructs are known in the art, and the antibodies provided herein may be provided in the form of any suitable multispecific suitable construct.
[00539] In some embodiments, the multispecific antibody comprises an immunoglobulin comprising at least two different heavy chain variable regions each paired with a common light chain variable region (i.e., a“common light chain antibody”). The common light chain variable region forms a distinct antigen-binding domain with each of the two different heavy chain variable regions. See Merchant et al., Nature Biotechnol. , 1998, 16:677-681, incorporated by reference in its entirety.
[00540] In some embodiments, the multispecific antibody comprises an immunoglobulin comprising an antibody or fragment thereof attached to one or more of the N- or C-termini of the heavy or light chains of such immunoglobulin. See Coloma and Morrison, Nature Biotechnol. , 1997, 15: 159-163, incorporated by reference in its entirety. In some aspects, such antibody comprises a tetravalent bispecific antibody.
[00541] In some embodiments, the multispecific antibody comprises a hybrid
immunoglobulin comprising at least two different heavy chain variable regions and at least two different light chain variable regions. See Milstein and Cuello, Nature , 1983, 305:537- 540; and Staerz and Bevan, Proc. Natl. Acad. Sci. USA , 1986, 83:1453-1457; each of which is incorporated by reference in its entirety.
[00542] In some embodiments, the multispecific antibody comprises immunoglobulin chains with alterations to reduce the formation of side products that do not have
multispecificity. In some aspects, the antibodies comprise one or more“knobs-into-holes” modifications as described in U.S. Pat. No. 5,731,168, incorporated by reference in its entirety. [00543] In some embodiments, the multispecific antibody comprises immunoglobulin chains with one or more electrostatic modifications to promote the assembly of Fc hetero- multimers. See WO 2009/089004, incorporated by reference in its entirety.
[00544] In some embodiments, the multispecific antibody comprises a bispecific single chain molecule. See Traunecker et al., EMBO J , 1991, 10:3655-3659; and Gruber et al., J Immunol ., 1994, 152:5368-5374; each of which is incorporated by reference in its entirety.
[00545] In some embodiments, the multispecific antibody comprises a heavy chain variable domain and a light chain variable domain connected by a polypeptide linker, where the length of the linker is selected to promote assembly of multispecific antibodies with the desired multispecificity. For example, monospecific scFvs generally form when a heavy chain variable domain and light chain variable domain are connected by a polypeptide linker of more than 12 amino acid residues. See U.S. Pat. Nos. 4,946,778 and 5,132,405, each of which is incorporated by reference in its entirety. In some embodiments, reduction of the polypeptide linker length to less than 12 amino acid residues prevents pairing of heavy and light chain variable domains on the same polypeptide chain, thereby allowing pairing of heavy and light chain variable domains from one chain with the complementary domains on another chain. The resulting antibodies therefore have multispecificity, with the specificity of each binding site contributed by more than one polypeptide chain. Polypeptide chains comprising heavy and light chain variable domains that are joined by linkers between 3 and 12 amino acid residues form predominantly dimers (termed diabodies). With linkers between 0 and 2 amino acid residues, trimers (termed triabodies) and tetramers (termed tetrabodies) are favored. However, the exact type of oligomerization appears to depend on the amino acid residue composition and the order of the variable domain in each polypeptide chain ( e.g ., VH- linker-VL vs. VL-linker-VH), in addition to the linker length. A skilled person can select the appropriate linker length based on the desired multispecificity.
[00546] In some embodiments, the multispecific antibody comprises a diabody. See Hollinger et al., Proc. Natl. Acad. Sci. USA , 1993, 90:6444-6448, incorporated by reference in its entirety.

[00548] In some embodiments, the multispecific antibody comprises a cross-linked antibody. See U.S. Patent No. 4,676,980; Brennan et al., Science , 1985, 229:81-83; Staerz, et al. Nature , 1985, 314:628-631; and EP 0453082; each of which is incorporated by reference in its entirety.
[00549] In some embodiments, the multispecific antibody comprises antigen-binding domains assembled by leucine zippers. See Kostelny et al., J Immunol ., 1992, 148: 1547- 1553, incorporated by reference in its entirety.
[00550] In some embodiments, the multispecific antibody comprises complementary protein domains. In some aspects, the complementary protein domains comprise an anchoring domain (AD) and a dimerization and docking domain (DDD). In some embodiments, the AD and DDD bind to each other and thereby enable assembly of multispecific antibody structures via the“dock and lock” (DNL) approach. Antibodies of many specificities may be
assembled, including bispecific antibodies, trispecific antibodies, tetraspecific antibodies, quintspecific antibodies, and hexaspecific antibodies. Multispecific antibodies comprising complementary protein domains are described, for example, in U.S. Pat. Nos. 7,521,056; 7,550,143; 7,534,866; and 7,527,787; each of which is incorporated by reference in its entirety.

[00556] In some embodiments, the multispecific antibody comprises an antibody fragment attached to another antibody or fragment. The attachment can be covalent or non-covalent. When the attachment is covalent, it may be in the form of a fusion protein or via a chemical linker. Illustrative examples of multispecific antibodies comprising antibody fragments attached to other antibodies include tetravalent bispecific antibodies, where an scFv is fused to the C-terminus of the Cro from an IgG. See Coloma and Morrison, Nature Biotechnol. , 1997, 15: 159-163. Other examples include antibodies in which a Fab molecule is attached to the constant region of an immunoglobulin. See Miler et al., J. Immunol ., 2003, 170:4854- 4861, incorporated by reference in its entirety.

2.6. Glycosylation Variants
[00562] In certain embodiments, an antibody provided herein may be altered to increase, decrease or eliminate the extent to which it is glycosylated. Glycosylation of polypeptides is typically either“N-linked” or“O-linked.”
[00563] “N-linked” glycosylation refers to the attachment of a carbohydrate moiety to the side chain of an asparagine residue. The tripeptide sequences asparagine-X-serine and asparagine-X-threonine, where X is any amino acid except proline, are the recognition sequences for enzymatic attachment of the carbohydrate moiety to the asparagine side chain. Thus, the presence of either of these tripeptide sequences in a polypeptide creates a potential glycosylation site.
[00564] “ O-linked” glycosylation refers to the attachment of one of the sugars N- acetylgalactosamine, galactose, or xylose to a hydroxyamino acid, most commonly serine or threonine, although 5-hydroxyproline or 5-hydroxylysine may also be used.
[00565] Addition or deletion of N-linked glycosylation sites to or from an antibody provided herein may be accomplished by altering the amino acid sequence such that one or more of the above-described tripeptide sequences is created or removed. Addition or deletion of O-linked glycosylation sites may be accomplished by addition, deletion, or substitution of one or more serine or threonine residues in or to (as the case may be) the sequence of an antibody.
[00566] In some embodiments, an antibody provided herein comprises a glycosylation motif that is different from a naturally occurring antibody. Any suitable naturally occurring glycosylation motif can be modified in the antibodies provided herein. The structural and glycosylation properties of immunoglobulins, for example, are known in the art and summarized, for example, in Schroeder and Cavacini, J. Allergy Clin. Immunol ., 2010, l25:S4l-52, incorporated by reference in its entirety.
[00567] In some embodiments, an antibody provided herein comprises an IgGl Fc region with modification to the oligosaccharide attached to asparagine 297 (Asn 297). Naturally occurring IgGl antibodies produced by mammalian cells typically comprise a branched, biantennary oligosaccharide that is generally attached by an N-linkage to Asn 297 of the Cm domain of the Fc region. See Wright et ak, TIBTECH , 1997, 15:26-32, incorporated by reference in its entirety. The oligosaccharide attached to Asn 297 may include various carbohydrates such as mannose, N-acetyl glucosamine (GlcNAc), galactose, and sialic acid, as well as a fucose attached to a GlcNAc in the“stem” of the biantennary oligosaccharide structure.
[00568] In some embodiments, the oligosaccharide attached to Asn 297 is modified to create antibodies having altered ADCC. In some embodiments, the oligosaccharide is altered to improve ADCC. In some embodiments, the oligosaccharide is altered to reduce ADCC.
[00569] In some aspects, an antibody provided herein comprises an IgGl domain with reduced fucose content at position Asn 297 compared to a naturally occurring IgGl domain. Such Fc domains are known to have improved ADCC. See Shields et ak, J. Biol. Chem ., 2002, 277:26733-26740, incorporated by reference in its entirety. In some aspects, such antibodies do not comprise any fucose at position Asn 297. The amount of fucose may be determined using any suitable method, for example as described in WO 2008/077546, incorporated by reference in its entirety.
[00570] In some embodiments, an antibody provided herein comprises a bisected oligosaccharide, such as a biantennary oligosaccharide attached to the Fc region of the antibody that is bisected by GlcNAc. Such antibody variants may have reduced fucosylation and/or improved ADCC function. Examples of such antibody variants are described, for example, in WO 2003/011878; U.S. Pat. No. 6,602,684; and U.S. Pat. Pub. No.
2005/0123546; each of which is incorporated by reference in its entirety.
[00571] Other illustrative glycosylation variants which may be incorporated into the antibodies provided herein are described, for example, in U.S. Pat. Pub.

4. Methods for Making TF Antibodies
4.1. TF Antigen Preparation
[00594] The TF antigen used for isolation of the antibodies provided herein may be intact TF or a fragment of TF. The TF antigen may be, for example, in the form of an isolated protein or a protein expressed on the surface of a cell.
[00595] In some embodiments, the TF antigen is a non-naturally occurring variant of TF, such as a TF protein having an amino acid sequence or post-translational modification that does not occur in nature.
[00596] In some embodiments, the TF antigen is truncated by removal of, for example, intracellular or membrane-spanning sequences, or signal sequences. In some embodiments, the TF antigen is fused at its C-terminus to a human IgGl Fc domain or a polyhistidine tag.
4.2. Methods of Making Monoclonal Antibodies
[00597] Monoclonal antibodies may be obtained, for example, using the hybridoma method first described by Kohler et al., Nature , 1975, 256:495-497 (incorporated by reference in its entirety), and/or by recombinant DNA methods ( see e.g., U.S. Patent No. 4,816,567, incorporated by reference in its entirety). Monoclonal antibodies may also be obtained, for example, using phage-display libraries (see e.g. , U.S. Patent No. 8,258,082, which is incorporated by reference in its entirety) or, alternatively, using yeast-based libraries (see e.g, U.S. Patent No. 8,691,730, which is incorporated by reference in its entirety).
[00598] In the hybridoma method, a mouse or other appropriate host animal is immunized to elicit lymphocytes that produce or are capable of producing antibodies that will specifically bind to the protein used for immunization. Alternatively, lymphocytes may be immunized in vitro. Lymphocytes are then fused with myeloma cells using a suitable fusing agent, such as polyethylene glycol, to form a hybridoma cell. See Goding J.W., Monoclonal Antibodies: Principles and Practice 3rd ed. (1986) Academic Press, San Diego, CA, incorporated by reference in its entirety.
[00599] The hybridoma cells are seeded and grown in a suitable culture medium that contains one or more substances that inhibit the growth or survival of the unfused, parental myeloma cells. For example, if the parental myeloma cells lack the enzyme hypoxanthine guanine phosphoribosyl transferase (HGPRT or HPRT), the culture medium for the hybridomas typically will include hypoxanthine, aminopterin, and thymidine (HAT medium), which substances prevent the growth of HGPRT-deficient cells.
[00600] Useful myeloma cells are those that fuse efficiently, support stable high-level production of antibody by the selected antibody-producing cells, and are sensitive media conditions, such as the presence or absence of HAT medium. Among these, preferred myeloma cell lines are murine myeloma lines, such as those derived from MOP-21 and MC- 11 mouse tumors (available from the Salk Institute Cell Distribution Center, San Diego, CA), and SP-2 or X63-Ag8-653 cells (available from the American Type Culture Collection, Rockville, MD). Human myeloma and mouse-human heteromyeloma cell lines also have been described for the production of human monoclonal antibodies. See e.g., Kozbor, J. Immunol ., 1984, 133:3001, incorporated by reference in its entirety.
[00601] After the identification of hybridoma cells that produce antibodies of the desired specificity, affinity, and/or biological activity, selected clones may be subcloned by limiting dilution procedures and grown by standard methods. See Goding, supra. Suitable culture media for this purpose include, for example, D-MEM or RPMI-1640 medium. In addition, the hybridoma cells may be grown in vivo as ascites tumors in an animal.
[00602] DNA encoding the monoclonal antibodies may be readily isolated and sequenced using conventional procedures (e.g, by using oligonucleotide probes that are capable of binding specifically to genes encoding the heavy and light chains of the monoclonal antibodies). Thus, the hybridoma cells can serve as a useful source of DNA encoding antibodies with the desired properties. Once isolated, the DNA may be placed into expression vectors, which are then transfected into host cells such as bacteria (e.g, E. coli ), yeast (e.g, Saccharomyces or Pichia sp.), COS cells, Chinese hamster ovary (CHO) cells, or myeloma cells that do not otherwise produce antibody, to produce the monoclonal antibodies.
4.3. Methods of Making Chimeric Antibodies [00603] Illustrative methods of making chimeric antibodies are described, for example, in U.S. Pat. No. 4,816,567; and Morrison et al., Proc. Natl. Acad. Sci. USA, 1984, 81 :6851- 6855; each of which is incorporated by reference in its entirety. In some embodiments, a chimeric antibody is made by using recombinant techniques to combine a non-human variable region ( e.g ., a variable region derived from a mouse, rat, hamster, rabbit, or non human primate, such as a monkey) with a human constant region.
4.4. Methods of Making Humanized Antibodies
[00604] Humanized antibodies may be generated by replacing most, or all, of the structural portions of a non-human monoclonal antibody with corresponding human antibody sequences. Consequently, a hybrid molecule is generated in which only the antigen-specific variable, or CDR, is composed of non-human sequence. Methods to obtain humanized antibodies include those described in, for example, Winter and Milstein, Nature , 1991, 349:293-299; Rader et al., Proc. Nat. Acad. Sci. U.S.A., 1998, 95:8910-8915; Steinberger et al., J. Biol. Chem., 2000, 275:36073-36078; Queen et al., Proc. Natl. Acad. Sci. U.S. A., 1989, 86: 10029-10033; and U.S. Patent Nos. 5,585,089, 5,693,761, 5,693,762, and 6,180,370; each of which is incorporated by reference in its entirety.
4.5. Methods of Making Human Antibodies
[00605] Human antibodies can be generated by a variety of techniques known in the art, for example by using transgenic animals (e.g., humanized mice). See, e.g, Jakobovits et al., Proc. Natl. Acad. Sci. U.S.A., 1993, 90:2551; Jakobovits et al., Nature, 1993, 362:255-258; Bruggermann et ak, Year in Immuno., 1993, 7:33; and U.S. Patent Nos. 5,591,669, 5,589,369 and 5,545,807; each of which is incorporated by reference in its entirety. Human antibodies can also be derived from phage-display libraries ( see e.g, Hoogenboom et al., J. Mol. Biol., 1991, 227:381-388; Marks et al., J. Mol. Biol., 1991, 222:581-597; and U.S. Pat. Nos.
5,565,332 and 5,573,905; each of which is incorporated by reference in its entirety). Human antibodies may also be generated by in vitro activated B cells (see e.g, U.S. Patent.

4.9. Methods of Making Variants
[00610] In some embodiments, an antibody provided herein is an affinity matured variant of a parent antibody, which may be generated, for example, using phage display-based affinity maturation techniques. Briefly, one or more CDR residues may be mutated and the variant antibodies, or portions thereof, displayed on phage and screened for affinity. Such alterations may be made in CDR“hotspots,” or residues encoded by codons that undergo mutation at high frequency during the somatic maturation process (see Chowdhury, Methods Mol. Biol., 2008, 207: 179-196, incorporated by reference in its entirety), and/or residues that contact the antigen.
[00611] Any suitable method can be used to introduce variability into a polynucleotide sequence(s) encoding an antibody, including error-prone PCR, chain shuffling, and oligonucleotide-directed mutagenesis such as trinucleotide-directed mutagenesis (TRIM). In some aspects, several CDR residues ( e.g ., 4-6 residues at a time) are randomized. CDR residues involved in antigen binding may be specifically identified, for example, using alanine scanning mutagenesis or modeling. CDR-H3 and CDR-L3 in particular are often targeted for mutation.
[00612] The introduction of diversity into the variable regions and/or CDRs can be used to produce a secondary library. The secondary library is then screened to identify antibody variants with improved affinity. Affinity maturation by constructing and reselecting from secondary libraries has been described, for example, in Hoogenboom et al., Methods in Molecular Biology, 2001, 178:1-37, incorporated by reference in its entirety.

[00613] Also provided are isolated nucleic acids encoding TF antibodies, vectors comprising the nucleic acids, and host cells comprising the vectors and nucleic acids, as well as recombinant techniques for the production of the antibodies.
[00614] For recombinant production of an antibody, the nucleic acid(s) encoding it may be isolated and inserted into a replicable vector for further cloning ( i.e ., amplification of the DNA) or expression. In some aspects, the nucleic acid may be produced by homologous recombination, for example as described in U.S. Patent No. 5,204,244, incorporated by reference in its entirety.
[00615] Many different vectors are known in the art. The vector components generally include one or more of the following: a signal sequence, an origin of replication, one or more marker genes, an enhancer element, a promoter, and a transcription termination sequence, for example as described in U.S. Patent No. 5,534,615, incorporated by reference in its entirety.
[00616] Illustrative examples of suitable host cells are provided below. These host cells are not meant to be limiting, and any suitable host cell may be used to produce the antibodies provided herein.
[00617] Suitable host cells include any prokaryotic (e.g, bacterial), lower eukaryotic (e.g, yeast), or higher eukaryotic (e.g, mammalian) cells. Suitable prokaryotes include eubacteria, such as Gram-negative or Gram-positive organisms, for example, Enterobacteriaceae such as Escherichia (E. coli), Enterobacter, Erwinia, Klebsiella, Proteus, Salmonella (S.
typhimurium), Serratia (S. marcescans), Shigella, Bacilli (B. subtilis and B. licheniformis), Pseudomonas (P. aeruginosa), and Streptomyces. One useful E. coli cloning host is E. coli 294, although other strains such as E. coli B, E. coli X1776, and E. coli W3110 are also suitable.
[00618] In addition to prokaryotes, eukaryotic microbes such as filamentous fungi or yeast are also suitable cloning or expression hosts for TF antibody-encoding vectors.
Saccharomyces cerevisiae, or common baker’s yeast, is a commonly used lower eukaryotic host microorganism. However, a number of other genera, species, and strains are available and useful, such as Schizosaccharomyces pombe , Kluyveromyces (K. lactis , K. fragilis, K. bulgaricus K. wickeramii , K. waltii , K. drosophilarum , K. thermotolerans , and K.
marxianus ), Yarrowia, Pichia pastoris , Candida ( C . albicans ), Trichoderma reesia ,
Neurospora crassa, Schwanniomyces ( S . occidentals), and filamentous fungi such as, for example Penicillium, Tolypocladium , and Aspergillus (A. nidulans and A. nigef).
[00619] Useful mammalian host cells include COS-7 cells, HEK293 cells, baby hamster kidney (BHK) cells, Chinese hamster ovary (CHO), mouse sertoli cells, African green monkey kidney cells (VERO-76), and the like.
[00620] The host cells used to produce the TF antibody of this invention may be cultured in a variety of media. Commercially available media such as, for example, Ham’s F10, Minimal Essential Medium (MEM), RPMI-1640, and Dulbecco’s Modified Eagle’s Medium (DMEM) are suitable for culturing the host cells. In addition, any of the media described in Ham et ah, Meth. Enz., 1979, 58:44; Barnes et ah, Anal. Biochem., 1980, 102:255; and U.S. Patent Nos. 4,767,704, 4,657,866, 4,927,762, 4,560,655, and 5,122,469; or WO 90/03430 and WO 87/00195 may be used. Each of the foregoing references is incorporated by reference in its entirety.
[00621] Any of these media may be supplemented as necessary with hormones and/or other growth factors (such as insulin, transferrin, or epidermal growth factor), salts (such as sodium chloride, calcium, magnesium, and phosphate), buffers (such as HEPES), nucleotides (such as adenosine and thymidine), antibiotics, trace elements (defined as inorganic compounds usually present at final concentrations in the micromolar range), and glucose or an equivalent energy source. Any other necessary supplements may also be included at appropriate concentrations that would be known to those skilled in the art.
[00622] The culture conditions, such as temperature, pH, and the like, are those previously used with the host cell selected for expression, and will be apparent to the ordinarily skilled artisan.
[00623] When using recombinant techniques, the antibody can be produced intracellularly, in the periplasmic space, or directly secreted into the medium. If the antibody is produced intracellularly, as a first step, the particulate debris, either host cells or lysed fragments, is removed, for example, by centrifugation or ultrafiltration. For example, Carter et al.
( Bio/Technology , 1992, 10: 163-167, incorporated by reference in its entirety) describes a procedure for isolating antibodies which are secreted to the periplasmic space of E. coli. Briefly, cell paste is thawed in the presence of sodium acetate (pH 3.5), EDTA, and phenylmethylsulfonylfluoride (PMSF) over about 30 min. Cell debris can be removed by centrifugation.
[00624] In some embodiments, the antibody is produced in a cell-free system. In some aspects, the cell-free system is an in vitro transcription and translation system as described in Yin et al., mAbs , 2012, 4:217-225, incorporated by reference in its entirety. In some aspects, the cell-free system utilizes a cell-free extract from a eukaryotic cell or from a prokaryotic cell. In some aspects, the prokaryotic cell is E. coli. Cell-free expression of the antibody may be useful, for example, where the antibody accumulates in a cell as an insoluble aggregate, or where yields from periplasmic expression are low.
[00625] Where the antibody is secreted into the medium, supernatants from such expression systems are generally first concentrated using a commercially available protein concentration filter, for example, an Amicon® or Millipore® Pellcon® ultrafiltration unit. A protease inhibitor such as PMSF may be included in any of the foregoing steps to inhibit proteolysis and antibiotics may be included to prevent the growth of adventitious
contaminants.
[00626] The antibody composition prepared from the cells can be purified using, for example, hydroxylapatite chromatography, gel electrophoresis, dialysis, and affinity chromatography, with affinity chromatography being a particularly useful purification technique. The suitability of protein A as an affinity ligand depends on the species and isotype of any immunoglobulin Fc domain that is present in the antibody. Protein A can be used to purify antibodies that comprise human gΐ, g2, or g4 heavy chains (Lindmark et al., ./. Immunol. Meth ., 1983, 62: 1-13, incorporated by reference in its entirety). Protein G is useful for all mouse isotypes and for human g3 (Guss et al., EMBO J, 1986, 5: 1567-1575, incorporated by reference in its entirety).
[00627] The matrix to which the affinity ligand is attached is most often agarose, but other matrices are available. Mechanically stable matrices such as controlled pore glass or poly(styrenedivinyl)benzene allow for faster flow rates and shorter processing times than can be achieved with agarose. Where the antibody comprises a Cm domain, the BakerBond ABX® resin is useful for purification. [00628] Other techniques for protein purification, such as fractionation on an ion-exchange column, ethanol precipitation, Reverse Phase HPLC, chromatography on silica,
chromatography on heparin Sepharose®, chromatofocusing, SDS-PAGE, and ammonium sulfate precipitation are also available, and can be applied by one of skill in the art.
[00629] Following any preliminary purification step(s), the mixture comprising the antibody of interest and contaminants may be subjected to low pH hydrophobic interaction chromatography using an elution buffer at a pH between about 2.5 to about 4.5, generally performed at low salt concentrations ( e.g ., from about 0 to about 0.25 M salt).
5. Cytotoxic Agents
[00630] In some embodiments, ADCs provided herein comprise a cytotoxic agent. The cytotoxic agents provided herein include various anti-tumor or anti-cancer agents known in the art. In some embodiments, the cytotoxic agents cause destruction of cancer cells. In some embodiments, the cytotoxic agents inhibit the growth or proliferation of cancer cells.

In certain embodiments, the cytotoxic agent is monomethyl auristatin E (MMAE).
[00633] In some embodiments, the cytotoxic agent is a diagnostic agent, such as a radioactive isotope, a metal chelator, an enzyme, a fluorescent compound, a bioluminescent compound, or a chemiluminescent compound.
[00634] In some embodiments, the cytotoxic agent is a cytotoxic payload improved safety profile, for example XMT-1267 and other cytotoxic payloads described in Trail et ah, Pharmacol Ther , 2018, 181 : 126-142.
6. Linkers [00635] In some embodiments, ADCs provided herein comprise a linker. In some embodiments, an unbound linker comprises two reactive termini: an antibody conjugation reactive termini and an cytotoxic agent conjugation reactive termini. The antibody conjugation reactive terminus of the linker can be conjugated to the antibody through a cysteine thiol or lysine amine group on the antibody, typically a thiol-reactive group such as a double bond, a leaving group such as a chloro, bromo or iodo, an R-sulfanyl group or sulfonyl group, or an amine-reactive group such as a carboxyl group. The cytotoxic agent conjugation reactive terminus of the linker can be conjugated to the cytotoxic agent through formation of an amide bond with a basic amine or carboxyl group on the cytotoxin, typically a carboxyl or basic amine group.
[00636] In some embodiments, the linker is a non-cleavable linker. In some embodiments, the linker is a cleavable linker. In some embodiments, the cytotoxic agent is released from the ADC in a cell.
[00637] Suitable linkers of ADCs include labile linkers, acid labile linkers ( e.g ., hydrazone linkers), photolabile linkers, charged linkers, disulfide-containing linkers, peptidase-sensitive linkers (e.g., peptide linkers comprising amino acids, for example, valine and/or citrulline such as citrulline-valine or phenylalanine-lysine), b-glucuronide-linkers ( See e.g, Graaf et ah, Curr Pharm Des, 2002, 8: 1391-1403), dimethyl linkers (See e.g., Chari et ah, Cancer Research, 1992, 52: 127-131; U.S. Pat. No. 5,208,020), thio-ether linkers, or hydrophilic linkers (See e.g., Kovtun et ah, Cancer Res., 2010, 70:2528-2537). In certain embodiments, the cytotoxic agent is conjugated to the antibody using a valine-citrulline (vc) linker.
7. Methods for Making Antibody-Drug Conjugates
[00638] The antibody-drug conjugates (ADCs) provided herein can be made using a variety of bifunctional protein coupling agents such as BMPS, EMCS, GMBS, HBVS, LC- SMCC, MBS, MPBH, SBAP, SIA, SIAB, SMCC, SMPB, SMPH, sulfo-EMCS, sulfo- GMBS, sulfo-KMUS, sulfo-MBS, sulfoSIAB, sulfo-SMCC, and sulfo-SMPB, and SVSB (succinimidyl-(4-vinylsulfone )benzoate )). For example, a ricin immunotoxin can be prepared as described in Vitetta et ah, Science , 1987, 238: 1098. Addtionally, the ADCs can be prepared using any suitable methods as disclosed in the art, e.g, in Bioconjugate
Techniques, 2nd Ed., G. T. Hermanson, ed., Elsevier, San Francisco, 2008.
[00639] In some embodiments, the ADCs are made with site-specific conjugation techniques, resulting in homogeneous drug loading and avoiding ADC subpopulations with altered antigen-binding or pharmacokinetics. In some embodiments, "thiomabs" comprising cysteine substitutions at positions on the heavy and light chains are engineered to provide reactive thiol groups that do not disrupt immunoglobulin folding and assembly or alter antigen binding (Junutula et al., J. Immunol. Meth ., 2008, 332: 41-52; Junutula et al., Nat. Biotechnol. , 2008, 26: 925-932, ). In some embodiments, selenocysteine is co-translationally inserted into an antibody sequence by recoding the stop codon UGA from termination to selenocysteine insertion, allowing site specific covalent conjugation at the nucleophilic selenol group of selenocysteine in the presence of the other natural amino acids ( See e.g. , Hofer et al., Proc. Natl. Acad. Sci. USA, 2008, 105: 12451-12456; Hofer et al., Biochemistry, 2009, 48(50): 12047-12057). In certain embodiments, ADCs were synthesized as described in Behrens et al , Mol Pharm, 2015, 12:3986-98.

Example 1: Generation of TF Antibodies
[00701] Human, cynomolgus monkey, and mouse TF extracellular domain (ECD) fragments were expressed as C-terminal His or Fey fragment fusions. Expi293 cells
(ThermoFisher Scientific, Waltham, MA, ETSA) were transiently transfected as recommended by the manufacturer with pcDNA3.1 V5-HisA (ThermoFisher Scientific) encoding human, cynomolgus, or mouse TF ECD-His6 (TF-His; SEQ ID NOs:8l l, 815, and 819, respectively) or pFETSE-hlgGl-Fc (Invivogen, San Diego, CA, ETSA) encoding human, cynomolgus or mouse TF ECD-Fc (TF-Fc; SEQ ID NOs:8l2, 816, and 820, respectively). For the His- tagged proteins, cell culture supernatants cleared from cells by centrifugation were preconditioned with 330 mM sodium chloride and 13.3 mM imidazole. ETsing recommended procedures, the TF-His6 and TF-Fc proteins were purified by affinity chromatography with a HisTrap HP and MabSelect SuRe column (GE Healthcare Bio-Sciences, Marlborough, MA, ETSA), respectively. FVII-Fc expressed in Expi293 was purified by affinity chromatography with a MabSelect SuRe column, followed by size exclusion chromatography. The TF-His6 and TF-Fc proteins were biotinylated with a 15c molar excess of Sulfo-NHS-SS-biotin as recommended (ThermoFisher Scientific). The non-labeled and biotinylated proteins were further purified by size exclusion chromatography using a Superdex 200 Increase 10/300 column (GE Healthcare Bio-Sciences).
[00702] Human antibodies against human TF were generated by Adimab™ yeast-based antibody presentation using the biotinylated recombinant TF proteins as screening antigens, as described below. All antibodies against human TF were evaluated for cross-reactivity with cynomolgus monkey and mouse TF. The binding activity of the antibodies to human, cynomolgus monkey, and mouse TF is shown in Table 5.
[00703] I. Library interrogation and selection methodology for isolation of anti-TF antibodies
[00704] Naive library selections
[00705] Eight naive human synthetic yeast libraries each of -109 diversity were designed, generated, and propagated as described previously (see, e.g, W02009036379;
WQ2010105256; W02012009568; Xu et ak, Protein Eng Des Sel. , 2013, 26(l0):663-70). Eight parallel selections were performed, using the eight naive libraries for monomeric human TF selections.
[00706] For the first two rounds of selection, a magnetic bead sorting technique utilizing the Miltenyi MACS system was performed, essentially as described (Siegel et al., J Immunol Methods, 2004, 286(1-2): 141-53). Briefly, yeast cells (-1010 cells/library) were incubated with 10 nM of biotinylated human TF Fc-fusion antigen for 15 min at room temperature in FACS wash buffer PBS with 0.1% BSA. After washing once with 50 mL ice-cold wash buffer, the cell pellet was resuspended in 40 mL wash buffer, and 500 pl Streptavidin MicroBeads (Miltenyi Biotec, Bergisch Gladbach, Germany; Cat # 130-048-101) were added to the yeast and incubated for 15 min at 4°C. Next, the yeast were pelleted, resuspended in 5 mL wash buffer, and loaded onto a MACS LS column (Miltenyi Biotec, Bergisch Gladbach, Germany; Cat.# 130-042-401). After the 5 mL was loaded, the column was washed 3 times with 3 mL FACS wash buffer. The column was then removed from the magnetic field, and the yeast were eluted with 5 mL of growth media and then grown overnight.
[00707] Subsequent to the two rounds of MACS, the following four rounds of sorting were performed using flow cytometry (FACS). For the first round of FACS, approximately 5x 107 yeast were pelleted, washed three times with wash buffer, and incubated with 10 nM of each the biotinylated Fc-fusion proteins of mouse and/or cynomolgus TF antigen for 10-15 min at room temperature. Yeast were then washed twice and stained with LC-FITC diluted 1 : 100 (Southern Biotech, Birmingham, Alabama; Cat# 2062-02) and either SA-633 (Life
Technologies, Grand Island, NY; Cat # S21375) diluted 1 :500, or EA-PE (Sigma-Aldrich, St Louis; Cat # E4011) diluted 1 :50, secondary reagents for 15 min at 4°C. After washing twice with ice-cold wash buffer, the cell pellets were resuspended in 0.4 mL wash buffer and transferred to strainer-capped sort tubes. Sorting was performed using a FACS ARIA sorter (BD Biosciences), and sort gates were determined to select for TF binding. The mouse- and cyno-selected populations from the first round of FACS were grown out and expanded through sub-culturing in selective media. The second, third, and fourth rounds of FACS involved positive sorts to enrich for TF binders and/or negative sorts to decrease the number of non-specific binders using soluble membrane proteins from CHO cells (see, e.g. ,
WO2014179363 and Xu et al., PEDS, 2013, 26(l0):663-70). After the final round of sorting, yeast were plated and sequenced.
[00708] Affinity maturation of clones identified in naive selections
[00709] Heavy chains from the naive outputs (described above) were used to prepare light chain diversification libraries, which were then used for additional selection rounds. In particular, heavy chain variable regions were extracted from the fourth naive selection round outputs and transformed into a light chain library with a diversity of 1 x 106.
[00710] The first of selection round utilized Miltenyi MACS beads and 10 nM biotinylated human TF Fc-fusion as antigen. Subsequent to the MACS bead selections, three rounds of FACS sorting were performed as described above using cynomolgus and mouse Fc-fusion TF at 10 nM oreither biotinylated Fc-fusion TF antigens or biotinylated monomeric HIS-forms of human, mouse or cynomolgus TF. Individual colonies from each FACS selection round were sequenced.
[00711] Optimization of leads identified from naive or light chain diversification selections
[00712] Optimization of lead clones was carried out utilizing three maturation strategies: diversification of CDR-H1 and CDR-H2; diversification of CDR-H3 following CDR-H1 and CDR-H2 diversity pool optimization; and diversification of CDR-L3 within selected CDR-L1 and CDR-L2 diversity pools.
[00713] CDR-H1 and CDR-H2 selection: The CDR-FBs from clones selected from either naive or light chain diversification procedure were recombined into a premade library with CDR-H1 and CDR-H2 variants of a diversity of 1 x 108 and selections were performed using biotinylated Fc-fusion cynomolgus TF antigen, biotinylated cynomolgus HIS-TF antigen, and/or biotinylated human HIS-TF. Affinity pressures were applied by using decreasing concentrations of biotinylated HIS-TF antigens (down to 1 nM) under equilibrium conditions at room temperature.
[00714] CDR-H3/CDR-H1/CDR-H2 selections: Oligos were ordered from IDT which comprised the CDR-H3 as well as a homologous flanking region on either side of the CDR- H3. Amino acid positions in the CDR-H3 were variegated via NNK diversity at two positions per oligo across the entire CDR-H3. The CDR-H3 oligos were double-stranded using primers which annealed to the flanking region of the CDR-H3. The remaining FR1 to FR3 of the heavy chain variable region was amplified from pools of antibodies with improved affinity that were isolated from the CDR-H1 and CDR-H2 diversities selected above. The library was then created by transforming the double stranded CDR-H3 oligo, the FR1 to FR3 pooled fragments, and the heavy chain expression vector into yeast already containing the light chain of the parent. Selections were performed as during previous cycles using FACS sorting.
FACS rounds assessed non-specific binding, species cross-reactivity, and affinity pressure, and sorting was performed to obtain populations with the desired characteristics. Affinity pressures for these selections were performed as described above in the CDR-H1 and CDR- H2 selection. [00715] CDR-L3/CDR-L1/CDR-L2 selections: Oligos were ordered from IDT which comprised the CDR-L3 as well as a homologous flanking region on either side of the CDR- L3. Amino acid positions in the CDR-L3 were variegated via NNK diversity at one position per oligo across the entire CDR-L3. The CDR-L3 oligos were double-stranded using primers which annealed to the flanking region of the CDR-L3. The remaining FR1 to FR3 of the light chain variable region was amplified from pools of antibodies with improved affinity that were isolated from the CDR-L1 and CDR-L2 diversities selected above. The library was then created by transforming the double stranded CDR-L3 oligo, the FR1 to FR3 pooled fragments, and the light chain expression vector into yeast already containing the heavy chain of the parent. Selections were performed as during previous cycles using FACS sorting.
FACS rounds assessed non-specific binding, species cross-reactivity, and affinity pressure, and sorting was performed to obtain populations with the desired characteristics. Affinity pressures included titrations as well as incorporation of the parental Fab in antigen pre- complexation.
[00716] II. IgG and Fab production and purification
[00717] In order to produce sufficient amounts of selected antibodies for further characterization, the yeast clones were grown to saturation and then induced for 48 h at 30°C with shaking. After induction, yeast cells were pelleted and the supernatants were harvested for purification. IgGs were purified using a Protein A column and eluted with acetic acid, pH 2.0. Fab fragments were generated by papain digestion and purified over CaptureSelect IgG- CH1 affinity matrix (LifeTechnologies, Cat # 1943200250).
Example 2: Binding Affinity Assay
[00718] Kinetic measurements for the anti-TF antibodies were conducted on an Octet QK384 (Pall ForteBio, Fremont, CA, USA) or a Biacore (GE Healthcare Bio-Sciences).
[00719] ForteBio affinity measurements were performed generally as previously described (Estep et al. , MAbs. 2013 Mar-Apr;5(2):270-8). Briefly, ForteBio affinity measurements were performed by loading IgGs on-line onto AHC sensors. Sensors were equilibrated off line in assay buffer for 30 min and then monitored on-line for 60 seconds for baseline establishment. Sensors with loaded IgGs were exposed to 100 nM antigen (human, cynomolgus, or mouse TF) for 3 min, afterwards they were transferred to assay buffer for 3 min for off-rate measurement. Alternatively, binding measurements were obtained by loading biotinylated TF monomer on SA sensors followed by exposure to 100 nM antibody Fab in solution. Kinetic data was analyzed and fitted using a 1 : 1 Langmuir binding model and the KD was calculated by dividing the k0ff by the k0n. The KD values of the TF antibodies measured by the Octet-based experiments are shown in Table 5.
[00720] For the Biacore-based measurements, the antibody was covalently coupled to a CM5 or Cl chip using an amine-coupling kit (GE Healthcare Bio-Sciences). Association between the anti-TF antibodies and a five-point three-fold titration of TF-His starting at 25 to 500 nM was measured for 300 sec. Subsequently, dissociation between the anti-TF antibody and TF-His was measured for up to 1800 sec. Kinetic data was analyzed and fitted globally using a 1 : 1 binding model. The KD values of the TF antibodies measured by the Biacore- based experiments are shown in Table 5.
[00721] As shown in Table 5, the affinity of the antibodies for hTF, as indicated by KD, is between 10-7 M and 10-11 M. All anti-hTF antibodies are cross-reactive with cTF. In addition, all anti-hTF antibodies from groups 25 and 43 exhibit binding activity to mTF. The anti-hTF antibodies 25G, 25G1, 25G9, and 43D8 are cross-reactive with mTF. There are no other known human or humanized anti-hTF monoclonal antibodies that exhibit binding activity and cross-reactivity to mouse TF, indicating that the antibodies from groups 25 and 43 bind to a novel TF epitope.

Example 3: Cell-Based Binding Assay
[00722] HCT116 cells with endogenous expression of human TF were obtained from the American Tissue Culture Collection (ATCC, Manassas, VA, USA) and were maintained as recommended. Flp-In-CHO cells expressing mouse TF were generated by transfection of Flp- In-CHO cells as recommended with a pcDNA5/FRT vector (ThermoFisher Scientific) encoding full-length mouse TF with a C-terminal FLAG tag. A mouse TF-positive CHO clone was isolated by limiting dilution in tissue culture-treated 96-well plates.
[00723] Cell-based antibody binding was assessed as previously described in Liao-Chan et al., PLoS One, 2015, l0:e0l24708, which is incorporated by reference in its entirety. l.2xl05 cells collected with Cellstripper (Mediatech, Manassas, VA, USA) were incubated with a twelve-point 1 :3 dilution titration of anti-human TF IgGl or Fab antibody starting at 250 nM or 100 nM for 2 hr on ice. After 2 washes, cells labeled with IgGl or Fab were incubated for 30 min on ice with 150 nM of Goat Phycoerythrin (PE) F(ab’)2 fragment goat anti-human IgG, Fey fragment specific (Jackson ImmunoResearch, West Grove, PA, USA) or FITC- labeled F(ab’)2 fragment goat anti-human kappa (SouthernBiotech, Birmingham, AL, USA), respectively. After 2 washes, dead cells were labeled with TO-PRO-3 Iodide (ThermoFisher Scientific) and samples were analyzed on a CytoFLEX flow cytometer (Beckman Coulter, Brea, CA, USA) or Novocyte flow cytometer (ACEA Biosciences, San Diego, CA, USA). The median fluorescence intensities (MFIs) at each dilution were plotted and cell ECso’s were derived using a 4-parameter binding model in Prism (GraphPad, La Jolla, CA, USA). The results of binding of anti-TF antibodies to human TF-positive HCT-l 16 cells are shown in Figures 1A and IB. The results of binding of anti-TF antibodies to CHO cells expressing mouse TF are shown in Figures 2 A and 2B.
[00724] All anti-hTF antibodies in Figures 1A and IB exhibit high affinity to human TF- positive HCT-l 16 cells with an ECso ranging from about 687 pM to about 39 pM. Antibodies from groups 25 and 43 exhibit binding to CHO cells expressing mouse TF with an EC so ranging from about 455 nM to about 2.9 nM, as shown in Figures 2A and 2B. The binding activity to mouse TF is a unique property of the anti-hTF antibodies from groups 25 and 43. This is advantageous for pre-clinical studies of these antibodies with mouse models.
Example 4: Thrombin Generation Assay (TGA)
[00725] The TGA assay was performed using the calibrated-automated-thrombogram (CAT) instrument manufactured and distributed by STAGO. The test method design was equivalent to a standard CAT assay measurement, except that the plasma source was NPP in citrate/CTI. The anti-TF antibodies were titrated at 0, 10, 50 and 100 nM and mixed with normal pooled plasma (NPP) collected in 11 mM citrate supplemented with 100
microgram/mL of corn trypsin inhibitor (citrate/CTI). Relipidated TF was added to a 96-well assay plate, followed by addition of the antibody /NPP mixture. After a lO-min incubation or directly after combining the relipidated TF with antibody /NPP, thrombin generation was initiated by the addition of calcium and the thrombin substrate. The STAGO software was used to report the following parameters: Peak Ila (highest thrombin concentration generated [nM]); Lag Time (time to Ila generation [min]); ETP (endogenous thrombin potential, area under the curve [nM x min]); and ttPeak (time to Peak Ila [min]). Percent peak thrombin generation (% Peak Ila) and percent endogenous thrombin potential (% ETP) in the presence of each antibody relative to a no antibody plasma control on the same plate were also reported.
[00726] The Peak Ila, Lag Time, ETP, ttPeak, % Peak Ila, and % ETP in the presence of each antibody selected from 1F, 25A, 25A3, 25G1, 29E, 39A, 43B1, 43D7, 43Ea, and 54E without antibody incubation prior to addition of calcium and thrombin substrate are shown in Table 6. The Peak Ila, Lag Time, ETP, ttPeak, % Peak Ila, and % ETP in the presence of each antibody selected from 1F, 25A, 25A3, 25G1, 29E, 39A, 43B1, 43D7, 43Ea, and 54E with 10 min antibody incubation prior to addition of calcium and thrombin substrate are shown in Table 7. The % Peak Ila in the presence of titrations of anti-TF antibodies without antibody incubation prior to addition of calcium and thrombin substrate is plotted in Figure 3A. The % Peak Ila in the presence of titrations of anti-TF antibodies with 10 min antibody incubation prior to addition of calcium and thrombin substrate is plotted in Figure 3B.
[00727] The % Peak Ila is greater than 90% in the presence of antibodies from group 25, including 25A, 25A3, and 25G1. The % ETP is greater than 100% in the presence of antibodies from group 25, including 25 A, 25 A3, and 25G1. The % Peak Ila is greater than 40% in the presence of antibodies from group 43, including 43B 1, 43D7, and 43Ea. The % ETP is greater than 90% in the presence of antibodies from group 43, including 43B1, 43D7, and 43Ea.
[00728] This data indicates that antibodies from groups 25 and 43 allow normal thrombin generation, and therefore are not inhibitors of thrombin generation.

Example 5: FXa Conversion Assay
[00729] To evaluate the ability of TF:FVIIa to convert FX into FXa in the presence of human antibodies against TF, 5xl04 MDA-MB-231 cells (ATCC, Manassas, VA, ETSA) were plated into tissue culture-treated black 96-well plates (Greiner Bio-One, Monroe, NC, ETSA). After removal of the cell culture media and addition of a final concentration of 200 nM of FX in a HEPES buffer with 1.5 mM CaCb, cells were incubated with a titration of the antibodies for 15 min at 37°C. ETpon reconstitution of the binary TF:FVIIa complex with a final concentration of 20 nM of FVIIa, cells were incubated for 5 min at 37°C. After quenching the reaction with ethylenediaminetetraacetic acid (EDTA), generated FXa was measured with 50 mM of SN-7 6-amino- l-naphthalenesulfonamide-based fluorogenic substrate (Haematologic Technologies, Essex Junction, VT, ETSA) on an Envision plate reader equipped with an ETmbelliferone 355 excitation filter, an ETmbelliferone 460 emission filter, and a
LANCE/DELFIA top mirror (Perkin Elmer, Waltham, MA, ETSA). FXa conversion percentages (% FXa) in the presence of an anti-TF antibody titration relative to a no-antibody control are summarized in Table 8 and plotted in Figures 4A and 4B.
[00730] The FXa conversion percentage ranges from about 78% to about 120% in presence of different concentrations of antibodies from groups 25 and 43, including 25 A, 25A3, 25G, 25G1, 25G5, 25G9, 43B, 43B1, 43B7, 43D, 43D7, 43D8, 43E, and 43Ea.
[00731] This data indicates that anti-TF antibodies from groups 25 and 43 do not inhibit TF:FVIIa mediated FXa conversion from FX. This data also indicates that anti-TF antibodies from groups 25 and 43 have a human TF binding site that is distinct from the human TF binding site bound by FX.

Example 6: FVIIa Competition Assay
[00732] FVII-Fc conjugates were generated using Alexa Fluor 488 5-sulfo-dichlorophenol esters (ThermoFisher Scientific). Excess Alexa Fluor dye was removed from the conjugate preparations by gel filtration (ThermoFisher Scientific).
[00733] To evaluate competition between FVIIa and the human antibodies against TF, TF- positive MDA-MB-231 cells (ATCC, Manassas, VA, USA) were first incubated for 1 hr on ice with a titration of the human antibodies against TF. Subsequently, a final concentration of 20 nM of FVII-Fc conjugated to Alexa488 was added to the antibody cell mixture. After another 1 hr incubation on ice, cells were washed, stained with a viability dye, and analyzed by flow cytometry. The Alexa488 fluorescence data from viable cells was summarized using median fluorescence intensity. FVII-Fc binding was summarized with % FVII-Fc binding = [MFIantibody labeled cells— MFIunstained Cell s] / [MFIlgGl control labeled cells— MFIunstained Cells] .
Percentage of FVIIa binding (% FVIIa) in the presence of an anti-TF antibody titration relative to a no-antibody control is summarized in Table 9 and plotted in Figures 5A and 5B.
[00734] The FVIIa binding percentage ranges from about 76% to about 102% in the presence of antibodies of different concentrations from groups 25 and 43, including 25 A, 25A3, 25G, 25G1, 25G5, 25G9, 43B, 43B1, 43B7, 43D, 43D7, 43D8, 43E, and 43Ea.
[00735] This data indicates that anti-TF antibodies from groups 25 and 43 do not compete for binding to human TF with FVIIa. This data also indicates that anti-TF antibodies from groups 25 and 43 have a human TF binding site that is distinct from the human TF binding site bound by FVIIa.

Example 7: TF Signaling Assay
[00736] IL-8 and GM-CSF protein levels were measured as described previously in Hjortoe et al., Blood, 2004, 103:3029-3037. TF-positive MDA-MB-231 cells (ATCC, Manassas, VA, USA) that underwent a 2 hr serum starvation with Leibovitz’s L-15 medium were incubated with an 8-point 1 :2.5 titration starting at 100 nM of anti-TF antibody. After 30 min at 37°C, FVIIa (NovoSeven RT, Novo Nordisk, Bagsvaerd, Denmark) was added to the cells at a final concentration of 20 nM. 5 hr later cell culture supernatants were harvested and analyzed by ELISA for IL8 or GM-CSF as recommended (R&D Biosystems,
Minneapolis, MN, USA). A standard curve using recombinant IL8 or GM-CSF (R&D Biosystems, Minneapolis, MN, USA) was used in Prism to calculate cytokine concentration in the cell culture supernatants. Percent IL8 and GM-CSF (% IL8 and % GM-CSF) at reported antibody concentration were calculated relative to a no antibody control. The concentration of IL8 with the anti-TF antibody titration is plotted in Figures 6A and 6B and the % IL8 at different antibodies concentrations are shown in Table 10. The concentration of GM-CSF with the anti-TF antibody titration is plotted in Figures 6C and 6D and the % IL8 at different antibodies concentrations are shown in Table 11.
[00737] IL8 concentrations were reduced by more than 75% in the presence of the anti-TF antibodies at concentrations greater than or equal to 6.4 nM. GM-CSF concentrations were reduced by more than 60% in the presence of the anti-TF antibodies at concentrations greater than or equal to 6.4 nM.
[00738] This data indicates that all tested anti-TF antibodies inhibit FVIIa-dependent TF signaling.

Example 8: Antibody Competition Assay
[00739] Alexa Fluor antibodies were generated using Alexa Fluor 488 5-sulfo- dichlorophenol esters (ThermoFisher Scientific). Excess Alexa Fluor dye was removed from the antibody dye conjugate preparations by gel filtration (ThermoFisher Scientific).
[00740] To evaluate competition between a first human antibody against TF and 25 A, TF- positive A431 cells (ATCC, Manassas, VA, USA) were first incubated for 1 hr on ice with a titration of the first human antibody against TF. Subsequently, a final concentration of 20 nM of 25A conjugated to Alexa488 was added to the antibody cell mixture. After another 1 hr incubation on ice, cells were washed, stained with a viability dye, and analyzed by flow cytometry. The Alexa488 fluorescence data from viable cells was summarized using median fluorescence intensity. 25 A binding was summarized with % 25 A binding = [MFLmtibody labeled cells - MFIunstained Cells] / [MFIlgGl control labeled cells— MFIunstained Cell s] .
[00741] To evaluate competition between a first human antibody against TF and 43Ea, TF- positive A431 cells (ATCC, Manassas, VA, USA) were first incubated for 1 hr on ice with a titration of the first human antibody against TF. Subsequently, a final concentration of 20 nM of 43Ea conjugated to Alexa488 was added to the antibody cell mixture. After another 1 hr incubation on ice, cells were washed, stained with a viability dye, and analyzed by flow cytometry. The Alexa488 fluorescence data from viable cells was summarized using median fluorescence intensity. 43Ea binding was summarized with % 43Ea binding = [MFLmtibody labeled cells— MFIunstained Cell s] / [MFIlgGl control labeled cells— MFIunstained Cell s] .
[00742] % 25A binding and % 43Ea binding are shown in Table 12. Antibodies from group 25 and group 43 reduced the % 25 A binding and % 43Ea binding to less than 10%.
[00743] This data indicates that antibodies of group 25 and antibodies of group 43 compete with each other for binding to human TF, and may bind the same or an overlapping epitope of human TF.

Example 9: Cell Viability Assay
[00744] To evaluate internalization of the anti-TF antibodies, a cytotoxicity assay was conducted. Briefly, cells were plated in 384-well plates (Greiner Bio-One, Monroe, NC, USA) at 4xl03 cells per well in 40 mΐ of media. Antibodies and secondary anti-human Fc antibodies conjugated to the tubulin inhibitor mono-methyl auristatin F (MMAF) (Moradec, San Diego, CA, USA) were serially diluted starting at 5 and 30 nM, respectively. Plates were incubated for 3 days, followed by lysis in CellTiter-Glo (CTG) assay reagent (Promega, Madison, WI, USA). CTG luminescence was measured on an Envision plate reader and the mean and standard deviation of 4 replicates graphed in Prism. For each anti-TF antibody, the IC50 and its associated 95% confidence interval were calculated in Prism using a 4-parameter binding model.
[00745] Figures 7A and 7B show the cell viability as indicated by the level of
luminescence and the calculated IC50.
[00746] This data indicates that all anti-TF antibodies tested from groups 1, 25, 29, 39, 43, and 54 were effective in reducing the viability of TF-positive A431 cells.
Example 10: Thrombin Generation Assay (TGA)
[00747] The TGA assay was performed using the calibrated-automated-thrombogram (CAT) instrument manufactured and distributed by STAGO. The test method design was equivalent to a standard CAT assay measurement, except that the plasma source was normal pooled plasma (NPP) in citrate supplemented with com trypsin inhibitor (citrate/C TI). The anti-TF antibodies were titrated at 0, 10, 50 and 100 nM and mixed with normal pooled plasma (NPP) collected in 11 mM citrate supplemented with 100 microgram/mL of corn trypsin inhibitor (citrate/CTI). Relipidated TF was added to a 96-well assay plate, followed by addition of the antibody /NPP mixture. After a lO-min incubation or directly after combining the relipidated TF with antibody /NPP, thrombin generation was initiated by the addition of calcium and the thrombin substrate. The STAGO software was used to report the following parameters: Peak Ila (highest thrombin concentration generated [nM]); Lag Time (time to Ila generation [min]); ETP (endogenous thrombin potential, area under the curve [nM x min]); and ttPeak (time to Peak Ila [min]). Percent peak thrombin generation (% Peak Ila) and percent endogenous thrombin potential (% ETP) in the presence of each antibody relative to a no antibody plasma control on the same plate were also reported.
[00748] The Peak Ila, Lag Time, ETP, ttPeak, % Peak Ila, and % ETP in the presence of each antibody selected from 25A, 25A3, 25A5, 39A, 43B1, 43D7, 43Ea, and M1593 without antibody incubation prior to addition of calcium and thrombin substrate are shown in Table
37. The Peak Ila, Lag Time, ETP, ttPeak, % Peak Ila, and % ETP in the presence of each antibody selected from 25A, 25A3, 25A5, 39A, 43B1, 43D7, 43Ea, and M1593 with 10 min antibody incubation prior to addition of calcium and thrombin substrate are shown in Table
38. The % Peak Ila in the presence of titrations of anti-TF antibodies without antibody incubation prior to addition of calcium and thrombin substrate is plotted in Figure 8A. The % Peak Ila in the presence of titrations of anti-TF antibodies with 10 min antibody incubation prior to addition of calcium and thrombin substrate is plotted in Figure 8B. The Ml 593 antibody has a VH sequence of SEQ ID NO:82l and VL sequence of SEQ ID NO:822.
[00749] The % Peak Ila is 95% or greater in the presence of antibodies from group 25, including 25A, 25A3, and 25A5 without antibody pre-incubation. The % Peak Ila is 100% or greater in the presence of antibodies from group 25, including 25A, 25A3, and 25A5 with 10 min antibody pre-incubation. The % ETP is 99% or greater in the presence of the tested antibodies from group 25.
[00750] The % Peak Ila is greater than 50% but equal to or less than 96% in the presence of antibodies from group 43, including 43B1, 43D7, and 43Ea and anti-TF antibody M1593 without antibody pre-incubation. The % Peak Ila is greater than 40% but equal to or less than 93% in the presence of antibodies from group 43, including 43B1, 43D7, and 43Ea and anti- TF antibody M1593 with 10 min antibody pre-incubation. The % ETP is 92% or greater in the presence of the tested antibodies from group 43 and Ml 593 antibody.
[00751] This data indicates that antibodies from groups 25 and 43 allow normal thrombin generation, and therefore are not inhibitors of thrombin generation. The percent peak thrombin generation (% Peak Ila) is greater in the presence of antibodies of group 25 compared to antibodies of group 43 and Ml 593 antibody.

Example 11: Synthesis of Antibody-Drug Conjugates (ADCs)
[00752] Antibody-Drug Conjugates (ADCs) were synthesized as described in Behrens et al , Mol Pharm, 2015, 12:3986-98. 5 mg/mL of antibody in phosphate-buffered saline (PBS), pH 7.4 was reduced with 2.5 molar equivalents of Tris(2-carboxyehtyl)phosphine. After 2 hr at 37°C, the partially reduced antibody was cooled to room temperature and conjugated for 1 hr to 3 to 5 molar equivalents of MC-vc-PAB-MMAE (maleimidocaproyl-valine-citrulline-p- aminobenzoyloxycarbonyl-monomethyl auristatin E). The reaction was buffer exchanged into PBS to remove small molecular weight reagents. The drug-antibody ratio (DAR) of the resulting ADCs was 3-4. The DAR was determined with the following formula: Absorbance (248 nm) / Absorbance (280 nm) = (n x EXPAB[248 m] + Exantibody[248 m]) / (n x EXPAB[28O m] + Exantibody [280 nm]) with n as a variable for the DAR and Ex as the extinction coefficients of PAB and the antibody. Hydrophobic interaction chromatography and size exclusion
chromatography were used to corroborate the absorbance-based DAR estimation and to ensure the ADC preparation was at least 95% monomeric, respectively.
Example 12: Cytotoxicity Assays of Antibody-Drug Conjugates (ADCs)
[00753] To evaluate cytotoxicity of ADCs, TF-positive A431 and HPAF-II cells were plated in 384-well plates (Greiner Bio-One, Monroe, NC, ETSA) at 4xl03 cells per well in 40 pL of media. Anti-TF antibodies conjugated to MC-vc-PAB-MMAE were serially diluted starting at 5 nM. Plates were incubated for 3 to 4 days, followed by lysis in CellTiter-Glo (CTG) assay reagent (Promega, Madison, WI, ETSA). CTG luminescence was measured on an Envision plate reader and the mean and standard deviation of 4 replicates were graphed in Prism. For each ADC, the ICso and its associated 95% confidence interval were calculated in Prism using a 4-parameter binding model. [00754] Figures 9A and 9B show the cell viability as indicated by CTG luminescence and the calculated ICso in TF-positive A431 and HPAF-II cells, respectively. ADCs comprising anti-TF antibodies from groups 25, 43, and 39 conjugated to MC-vc-PAB-MMAE resulted in cytotoxicity in TF-positive A431 and HPAF-II cells.
[00755] This data indicates that anti-TF antibody-drug conjugates reduced the viability of TF-positive cells in vitro.
Example 13: Xenograft Cell Line Studies
[00756] Xenograft studies in immune compromised mice were performed to evaluate the efficacy of the ADCs in vivo. The TF-positive A431 epidermoid carcinoma and the HPAF-II pancreatic carcinoma xenografts were implanted subcutaneously in the flank of athymic nude mice (Charles River Laboratories, Wilmington, MA). Animals were randomized when tumors reached an average size of 150-200 mm3 and treated with 5 mg/kg of the indicated ADC or vehicle (PBS) intraperitoneally (i.p.) once weekly for 3 weeks. Body weight and tumor size assessments were performed bi-weekly. Animals were removed from study and euthanized once tumor size reached 1200 mm3 or skin ulceration was evident.
[00757] Figures 10A and 10B show the tumor size of vehicle-treated, IgGl ADC-treated, and anti-TF ADC-treated groups in the TF-positive A431 epidermoid carcinoma and the HPAF-II pancreatic carcinoma xenograft models, respectively. ADCs comprising anti-TF antibodies 25 A and 43Ea conjugated to MC-vc-PAB-MMAE decreased the tumor size in both xenograft models compared to the vehicle-treated or IgGl ADC-treated groups.
[00758] This data indicates that anti-TF antibody-drug conjugates 25A-vc-MMAE and 43Ea-vc-MMAE were effective in reducing the tumor size in vivo.
Example 14: Studies of Patient-Derived Xenograft (PDX) Model
[00759] A TF-positive head and neck cancer patient-derived xenograft model was generated in athymic nude mice (Envigo, Indianapolis, IN) to further evaluate the efficacy of the ADCs in vivo. Tumors were passaged in stock animals and harvested for re-implantation. Study animals were implanted unilaterally on the left flank with tumor fragments and were randomized to treatment group when tumors reached an average size of 150-200 mm3.
Animals were treated with 5 mg/kg of the indicated ADC intraperitoneally (i.p.) once weekly for 2 weeks. Body weight and tumor size assessments were performed bi-weekly. Animals were removed from study and euthanized once tumor size reached 1200 mm3 or skin ulceration was evident. [00760] Figure 11 shows the tumor size of IgGl ADC-treated and anti-TF ADC-treated groups in the head and neck cancer patient-derived xenograft model. ADCs comprising anti- TF antibodies 25A and 43Ea conjugated to MC-vc-PAB-MMAE decreased the tumor size in the cancer patient-derived xenograft model compared to the IgGl ADC-treated group.
[00761] This data indicates that anti-TF antibody-drug conjugates 25A-vc-MMAE and 43Ea-vc-MMAE were effective in reducing the tumor size in a cancer patient-derived xenograft model in vivo.
Example 15: Binding Affinity Assay For Pig TF
[00762] The ability of certain antibodies was tested for binding to pig TF. For pig TF Biacore-based measurements, a given anti-TF antibody was captured by an anti-human IgG antibody covalently coupled to a CM5 chip (GE Healthcare Bio-Sciences). Association between the anti-TF antibodies and a five-point three-fold titration of pig TF-His starting at 100 nM was measured for 180 to 240 sec. Subsequently, dissociation between the anti-TF antibody and TF-His was measured for 1800 sec. Kinetic data was analyzed and fitted globally using a 1 : 1 binding model. The KD values of the indicated TF antibodies measured by the Biacore-based experiments are shown in Table 40.
[00763] As shown in Table 40, anti-hTF antibodies from groups 25 and 43, 25G9 and 43D8, exhibit binding activity and cross-reactivity to pig TF.

Example 16: Cell-Based Binding Assay
[00764] Human TF-positive cancer cell lines A431 and MDA-MB-231 and Macaco mulatto TF-positive cell line RF/6A were obtained from the American Tissue Culture Collection (ATCC, Manassas, VA, ETSA) and were maintained as recommended.
[00765] Cell-based antibody binding was assessed as previously described in Liao-Chan et ak, PLoS One, 2015, l0:e0l24708, which is incorporated by reference in its entirety. l.2xl05 cells collected with Cellstripper (Mediatech, Manassas, VA, ETSA) were incubated with a twelve-point 1 :3 dilution titration of anti-human TF IgGl antibody starting at 250 nM or 100 nM for 2 hr on ice. After 2 washes, cells labeled with IgGl antibody were incubated for 30 min on ice with 150 nM of Goat Phycoerythrin (PE) F(ab’)2 fragment goat anti-human IgG, Fey fragment specific (Jackson ImmunoResearch, West Grove, PA, USA) or FITC-labeled F(ab’)2 fragment goat anti-human kappa (SouthemBiotech, Birmingham, AL, USA), respectively. After 2 washes, dead cells were labeled with TO-PRO-3 Iodide (ThermoFisher Scientific) and samples were analyzed on a CytoFLEX flow cytometer (Beckman Coulter, Brea, CA, USA) or Novocyte flow cytometer (ACEA Biosciences, San Diego, CA, USA). The median fluorescence intensities (MFIs) at each dilution were plotted and cell ECso’s were derived using a 4-parameter binding model in Prism (GraphPad, La Jolla, CA, USA).
Antibodies that does not substantially affect FX conversion (i.e. 25A, 25A3, 25G1, 43B1, 43D7 and 43Ea) and antibodies that inhibited FX conversion by more than 50 % (i.e. 1F,
29E, 39A and 54E) were included in the assay. The results of binding of anti-TF antibodies to human TF-positive A431 cells are shown in Figure 12A. The results of binding of anti-TF antibodies to human TF-positive MDA-MB-231 cells are shown in Figure 12B.
[00766] All tested anti-hTF antibodies in Figures 12A exhibit high affinity to human TF- positive A431 cells with an EC so ranging from about 1.50 nM to about 0.34 nM. An IgGl isotype control did not bind A431 cells (no binding, nb). All tested anti-hTF antibodies in Figures 12B exhibit high affinity to human TF-positive MDA-MB-231 cells with an ECso ranging from about 1.50 nM to about 0.06 nM. An IgGl isotype control did not bind MDA- MB-23 ! cells (no binding, nb).
[00767] As described in Example 2 and shown in Table 5, the binding affinity of anti-hTF antibodies was evaluated on TF from cynomolgus monkey ( Macaca fascicularis). The protein sequences of Macaca fascicularis TF and Macaca mulatta TF are identical. The binding of the TF-specific antibodies to cynomolgus monkey was confirmed using the Macaca mulatta RF/6A cell line as shown in Table 42. All tested anti-hTF antibodies exhibit high affinity to TF-positive Macaca mulatta RF/6A cells with an EC so ranging from about 1.28 nM to about 0.17 nM. The ability of the anti-TF antibodies to bind to cynomolgus monkey is advantageous for toxicology studies of these antibodies with nonhuman primate models.

Example 17: Binding Assay to E. Co/z--Derived TF
[00768] E. coli- derived TF was expressed as a fusion between the OmpA signal sequence and TF ECD-His6, and purified by affinity and anion exchange chromatography. The binding of anti-TF antibodies 1F, 25A, 25A3, 25G1, 29E, 39A, 43B1, 43D7, 43Ea, and 54E to Expi293- oris co/z-derived TF was determined by protein ELISA studies. Plates coated with Expi293- oris co/z-derived TF-His were incubated with increasing concentrations of antibodies. After incubation with an HRP-conjugated secondary antibody (Jackson
Immunoresearch), luminescence data were obtained and used to calculate an ECso with 95 % confidence intervals using Prism. The ECrio’s and 95% confidence intervals of the antibodies are listed in Table 43.
Table 43: Binding of anti-TF antibodies to Expi293- or E. coli-derived TF
Figure imgf000205_0002
[00769] All tested anti-hTF antibodies exhibit high affinity to E. coli- derived TF with an EC50 ranging from about 0.68 nM to about 0.31 nM, which is comparable to the binding affinity of the antibodies to Expi293 -derived TF (about 0.98 nM to 0.41 nM). These results indicate that although the anti-TF antibodies were selected against glycosylated TF from a human cell line, the antibodies can bind to E. coli- derived TF with similar affinity when measured by protein ELISA.
Example 18: Thrombin Generation Assay (TGA)
[00770] TGA assay was performed using the calibrated-automated-thrombogram (CAT) instrument manufactured and distributed by STAGO (Diagnostica Stago SAS, Asnieres sur Seine, France). See Samama et al., Thromb Res, 2012, l29:e77-82, which is incorporated by reference in its entirety. The test method design was equivalent to a standard CAT assay measurement, except that the plasma source was normal pooled plasma (NPP) collected in 11 mM citrate supplemented with 100 pg/mL of corn trypsin inhibitor (citrate/C TI). The anti-TF antibodies were titrated at 0, 10, 50 and 100 nM and mixed with NPP in citrate/CTI.
Relipidated TF was added to a 96-well assay plate, followed by addition of the antibody /NPP mixture. After a lO-min incubation or directly after combining the relipidated TF with antibody /NPP, thrombin generation was initiated by the addition of calcium and the thrombin substrate. The STAGO software was used to report the following parameters: Peak Ila (highest thrombin concentration generated on the thrombin generation curve [nM]); Lag Time (time from assay start to the moment 10 nM of thrombin is formed [min]); ETP
(endogenous thrombin potential, area under the curve [nM x min]); and ttPeak (time from assay start to Peak Ila [min]). Percent peak thrombin generation (% Peak Ila), percent endogenous thrombin potential (% ETP), and percent ttPeak (% ttPeak) in the presence of each antibody relative to a no-antibody plasma control on the same plate were also reported. As used herein, the term“thrombin generation assay” (TGA) refers to the TGA used in this example.
[00771] The Peak Ila, Lag Time, ETP, ttPeak, % Peak Ila, % ETP, and % ttPeak in the presence of each antibody selected from 1F, 25A, 25A3, 25G1, 29E, 39A, 43B1, 43D7, 43Ea, 54E, TF-011, 5G9, and 10H10 without antibody incubation prior to addition of calcium and thrombin substrate are shown in Table 44. The Peak Ila, Lag Time, ETP, ttPeak, % Peak Ila, % ETP, and % ttPeak in the presence of each antibody selected from 1F, 25A, 25A3, 25G1, 29E, 39 A, 43B1, 43D7, 43Ea, 54E, TF-011, 5G9, and 10H10 with 10 min antibody incubation prior to addition of calcium and thrombin substrate are shown in Table 45. The thrombin generation curve in the presence of 100 nM anti-TF antibody without antibody pre- incubation is plotted in Figures 13A and 13B. The Peak thrombin concentration in the presence of titrations of anti-TF antibodies without antibody pre-incubation is plotted in
Figure 13C.
[00772] As shown in Figures 13A, 13B, and 13C and Table 44, under the conditions without antibody pre-incubation, at the 100 nM antibody concentration, 1F, 29E, 39A, 54E diminished the peak Ila concentration by 92, 76, 91 and 70 %, respectively. Similarly, 100 nM of 5G9 and TF-011 inhibited peak Ila concentration by 92 % and 91 %, respectively. Severely reduced thrombin generation in the presence of the two highest concentrations of 1F, 39A, 5G9 and TF-011 hampered endogenous thrombin generation (ETP) calculations and increased time to Peak Ila/thrombin generation (ttPeak) by at least 284 % and 353 % at 50 nM and 100 nM respectively. In contrast, antibodies from group 25 did not impact the peak Ila concentration or ttPeak by more than 9 %. Group 43 antibodies and 10H10 exhibited mild interference with the peak Ila concentration: 100 nM of 43B1, 43D7, 43Ea and 10H10 reduced the peak Ila concentration by 33, 44, 13 and 34 %, respectively. In addition, 100 nM of 43B1, 43D7 and 10H10 showed at least a 29 % increase in ttPeak. However, the observed decline in peak Ila concentration and delayed ttPeak for group 43 antibodies and 10H10 did not result in more than a 10 % decline in the ETP.
[00773] Similar results are shown in Table 45 under the conditions with 10 min antibody pre-incubation. At the 100 nM antibody concentration, 1F, 29E, 39A, 54E diminished the peak Ila concentration by 93, 72, 93 and 87 %, respectively. Similarly, 100 nM of 5G9 and TF-011 inhibited peak Ila concentration by 92 % and 91 %, respectively. Severely reduced thrombin generation in the presence of the two highest concentrations of 1F, 39A, 54E and TF-011 and all tested concentrations of 5G9 hampered endogenous thrombin generation (ETP) calculations and increased time to Peak Ila/thrombin generation (ttPeak) by at least 303 % and 371 % at 50 nM and 100 nM respectively. In contrast, antibodies from group 25 did not decrease the peak Ila concentration or increase ttPeak. Group 43 antibodies and 10H10 exhibited mild interference with the peak Ila concentration: 100 nM of 43B1, 43D7, 43Ea and 10H10 reduced the peak Ila concentration by 41, 56, 13 and 48 %, respectively. In addition, 100 nM of 43B1, 43D7 and 10H10 showed at least a 33 % increase in ttPeak.
However, the observed decline in peak Ila concentration and delayed ttPeak for group 43 antibodies and 10H10 did not result in more than an 11 % decline in the ETP. [00774] Overall, these results indicate that group 25 antibodies are completely inert in the penultimate step of the coagulation cascade when all three TGA parameters (ETP, Peak Ila concentration and ttPeak) are taken into consideration.

Example 19: FXa Conversion Assay and FVIIa Competition Assay with
Previously Described Anti-TF Antibodies
[00775] The previously described TF-specific antibodies TF-011, 5G9 and 10H10 (Breij et al., Cancer Res, 2014, 74:1214-1226; Versteeg et al Blood, 2008,111 : 190-199; each of which is incorporated by reference in its entirety) were tested in FXa conversion assay and FVIIa competition assay.
[00776] To evaluate the ability of TF:FVIIa to convert FX into FXa in the presence of human antibodies against TF, a cell-based FX conversion assay was conducted as described in Larsen et al., J Biol Chem, 2010, 285: 19959-19966, which is incorporated by reference in its entirety. Briefly, 5xl04 MDA-MB-231 cells (ATCC, Manassas, VA, USA) were plated into tissue culture-treated black 96-well plates (Greiner Bio-One, Monroe, NC, USA) and cultured overnight. After removal of the cell culture media and addition of a final
concentration of 200 nM of FX in a HEPES buffer with 1.5 mM CaCb, cells were incubated with a titration of the antibodies for 15 min at 37°C. Upon reconstitution of the binary TF:FVIIa complex with a final concentration of 20 nM of F Vila, cells were incubated for 5 min at 37°C. After quenching the reaction with ethylenediaminetetraacetic acid (EDTA) in a black 94-well plate, generated FXa was measured with 50 mM of SN-7 6-amino-l- naphthalenesulfonamide-based fluorogenic substrate (Haematologic Technologies, Essex Junction, VT, USA) on an Envision plate reader equipped with an Umbelliferone 355 excitation filter, an Umbelliferone 460 emission filter, and a LANCE/DELFIA top mirror (Perkin Elmer, Waltham, MA, USA). FXa conversion percentages (% FXa) in the presence of an anti-TF antibody titration relative to a no antibody control are plotted in Figure 14A.
[00777] To evaluate competition between FVIIa and the human antibodies against TF, TF- positive MDA-MB-231 cells (ATCC, Manassas, VA, USA) were first incubated for 1 hr on ice with a titration of the human antibodies against TF or an isotype control. Subsequently, FVII-Fc conjugated to Alexa488 was added to the antibody-cell mixture at a final concentration of 20 nM. After another 1 hr incubation on ice, cells were washed, stained with a viability dye, and analyzed by flow cytometry. The Alexa488 fluorescence data from viable cells was summarized using median fluorescence intensity (MFI). FVII-Fc binding was summarized with % FVII-Fc binding = [MFLmtibody labeled ceils - MFUnstained cells] / [MFIigGi control labeled ceils - MFIunstained cells]. Percentage of FVIIa binding (% FVIIa) in the presence of an anti-TF antibody titration relative to an isotype control is plotted in Figure 14B.
[00778] As presented in Figure 14A, TF-011 and 5G9 inhibited FX conversion by 57-59 % and 67-70 % at concentrations of 25, 50, and 100 nM. 10H10 did not significantly inhibit FX conversion at these three concentraions.
[00779] As presented in Figure 14B, TF-011 effectively competed with FVII, whereas 5G9 and 10H10 showed less than 25 % and 10 % competition at the highest concentration of antibody, respectively.
[00780] These results indicate that 5G9 predominantly competes with substrate FX binding, resulting in the observed inhibition of FX conversion and thrombin generation. TF- 011 inhibits thrombin generation by competing with FVIIa for binding to TF. However, 10H10 inhibits TF-FVIIa mediated signaling without substantially affecting binding of FVIIa to TF. These findings are consistent with previous observations described in Huang et al., J Mol Biol, 1998, 275:873-894; Ruf et al., Biochem J, 1991, 278:729-733; and Teplyakov et al., Cell Signal, 2017, 36: 139-144; each of which is incorporated by reference in its entirety.
Example 20: Antibody Competition Assay
[00781] Alexa Fluor antibodies were generated using Alexa Fluor 488 5-sulfo- dichlorophenol esters (ThermoFisher Scientific) following manufacturer’s protocol. Excess Alexa Fluor dye was removed from the antibody dye conjugate preparations by gel filtration (ThermoFisher Scientific).
[00782] To evaluate competition between a first human antibody against TF and 25 A3, TF-positive MDA-MB-231 cells (ATCC, Manassas, VA, USA) were first incubated for 1 hr on ice with a titration of the first human antibody against TF. Subsequently, a final concentration of 20 nM of 25A3 conjugated to Alexa488 was added to the antibody cell mixture. After another 1 hr incubation on ice, cells were washed, stained with a viability dye, and analyzed by flow cytometry. The Alexa488 fluorescence data from viable cells was summarized using median fluorescence intensity. 25A3 binding was summarized with %
25 A3 binding = [MFIantibody labeled cells— MFIunstained Cell s] / [MFIlgGl control labeled cells— MFIunstained cells]
[00783] To evaluate competition between a first human antibody against TF and 43D7, TF-positive MDA-MB-231 cells (ATCC, Manassas, VA, USA) were first incubated for 1 hr on ice with a titration of the first human antibody against TF. Subsequently, a final concentration of 20 nM of 43D7 conjugated to Alexa488 was added to the antibody cell mixture. After another 1 hr incubation on ice, cells were washed, stained with a viability dye, and analyzed by flow cytometry. The Alexa488 fluorescence data from viable cells was summarized using median fluorescence intensity. 43D7 binding was summarized with % 43D7 binding = [MFIantibody labeled cells— MFIunstained Cell s] / [MFIlgGl control labeled cells— MFIunstained cells]
[00784] To evaluate competition between a first human antibody against TF and 39 A, TF- positive MDA-MB-231 cells (ATCC, Manassas, VA, USA) were first incubated for 1 hr on ice with a titration of the first human antibody against TF. Subsequently, a final concentration of 20 nM of 39A conjugated to Alexa488 was added to the antibody cell mixture. After another 1 hr incubation on ice, cells were washed, stained with a viability dye, and analyzed by flow cytometry. The Alexa488 fluorescence data from viable cells was summarized using median fluorescence intensity. 39A binding was summarized with % 39A binding =
[MFIantibody labeled cells— MFIunstained Cell s] / [MFIlgGl control labeled cells— MFIunstained Cells] .
[00785] % 25A3 binding, % 43D7 binding, and % 39A binding are shown in Figures 15A and 15B, Figures 16A and 16B, and Figures 17A and 17B, respectively. Antibodies from groups 25 and 43, 5G9, and 10H10 reduced % 25A3 binding and % 43D7 binding and did not reduce % 39A binding. Antibodies from groups 1, 29, 39, and 54, and TF-011 reduced % 39A binding and did not reduce % 25 A3 binding and % 43D7 binding.
[00786] While the antibody competition assay results indicate that groups 25 and 43 antibodies, 5G9, and 10H10 may bind to the same or an overlapping epitope of human TF or may affect the TF binding of each other through an allosteric mechanism, the chimeric TF construct mapping experiments as described elsewhere in this disclosure demonstrate that group 25 antibodies, group 43 antibodies, 5G9 and 10H10 bind distinct epitopes. In addition, while the antibody competition assay results indicate that antibodies of groups 1, 29, 39, and 54, and TF-011 may bind to the same or an overlapping epitope of human TF or may affect the TF binding of each other through an allosteric mechanism, the chimeric TF construct mapping experiments as described elsewhere in this disclosure demonstrate that the antibodies of groups 29, 39 and 54 bind epitopes distinct from TF-01 l’s epitope.
Example 21: Anti-TF Antibody Internalization
[00787] To evaluate internalization of the anti-TF antibodies, a cytotoxicity assay was conducted as described in Liao-Chan et al., PLoS One , 2015, l0:e0l24708, which is incorporated by reference in its entirety. Briefly, cells were plated in 384-well plates (Greiner Bio-One, Monroe, NC, USA) at 4xl03 cells per well in 40 mΐ of media. Antibodies and an anti-human Fc Fab conjugated to the tubulin inhibitor mono-methyl auristatin F (MMAF) (Moradec, San Diego, CA, USA) were serially diluted starting at 5 and 30 nM, respectively. The anti-human Fc Fab conjugated to MMAF consisted of a polyclonal antibody specific to the Fc region of human IgGs with a DAR of 1.2 to 1.5. Plates were incubated for 3 days, followed by lysis in CellTiter-Glo (CTG) assay reagent (Promega, Madison, WI, USA). CTG luminescence was measured on an Envision plate reader and the mean and standard deviation of 4 replicates graphed in Prism (GraphPad, La Jolla, CA, USA). For each anti-TF antibody, the IC50 and its associated 95% confidence interval were calculated in Prism using a 4- parameter binding model. The cell viability results after incubation with anti-TF antibodies and anti-TF antibody Fab:MMAF complexes are shown in Figures 18A and 18B. The 95% confidence intervals for the IC50 values are shown in Table 46. [00788] Internalization of the anti-TF antibodies was also evaluated by a quantitative assay based on internalized fluorescence and quenched surface-fluorescence. Cell surface fluorescence quenching was assessed as described in Liao-Chan et al., PLoS One ,
20l5,l0:e0l24708. Briefly, l.2xl05 MDA-MB-231 cells were pre-incubated with 100 nM of A488-conjugated antibodies in media for 2 hr on ice. After 2 washes, cells were resuspended in cold media and pulsed for up to 4 hr at 37°C. Cells were rapidly chilled and incubated with or without 300 nM of anti-A488 antibody (clone 19A) for 30 min on ice. After 2 washes, dead cells were labeled with DAPI and samples were analyzed on a Novocyte flow cytometer (ACEA Biosciences). The median fluorescence intensities (MFIs) at each anti-A488 mAh concentration were normalized against the isotype control to obtain a normalized MFI percentage. Internalized fluorescence was calculated from quenched and non-quenched sample data by correcting for incomplete surface quenching: l-(Ni-Qi)/(Ni- (NiQo/No)) with Ni = unquenched MFI at each time point (ti); Qi = Quenched MFI at ti; Qo = Quenched MFI for the sample kept on ice (to); No = Unquenched MFI at to. Percent internalization of anti-TF antibodies conjugated to A488 is shown in Figure 18C.
[00789] Because Fab:MMAF binds the Fc region of the TF-specific antibodies, cellular uptake of these complexes can trigger cell death. While the TF-specific antibodies alone had no impact on cell viability in three-day cultures of TF -positive A431 cells (Figure 18A), the TF-specific antibodies in complex with Fab:MMAF showed dose-dependent cell killing with IC50 values ranging between 0.07 and 0.14 nM (Figure 18B).
[00790] Cellular uptake was corroborated with fluorescently labeled TF-specific antibodies. In a quantitative assay based on internalized fluorescence and quenched surface- fluorescence, the TF-specific antibodies showed between 28 and 37 % internalization after a 4 h incubation (Figure 18C).
[00791] These results indicate that the tested anti-TF antibodies can medicate
internalization and toxin delivery into TF-positive cells.

Example 22: Cell-Based Binding Assay of Antibody-Drug Conjugates (ADCs)
[00792] To evaluate the cell binding properties of ADCs, binding of anti-TF antibodies and anti-TF ADCs to endogenous human TF expressing HCT116 cells was was assessed as previously described in Liao-Chan et al., PLoS One , 2015, l0:e0l24708, which is incorporated by reference in its entirety. Briefly, l.2xl05 cells collected with Cellstripper (Mediatech, Manassas, VA, USA) were incubated with a twelve-point 1 :3 dilution titration of anti-human TF antibody or ADC starting at 100 nM for 2 hr on ice. After 2 washes, cells labeled with antibody or ADC were incubated for 30 min on ice with 150 nM of Goat Phycoerythrin (PE) F(ab’)2 fragment goat anti-human IgG, Fey fragment specific (Jackson ImmunoResearch, West Grove, PA, USA) or FITC-labeled F(ab’)2 fragment goat anti-human kappa (SouthernBiotech, Birmingham, AL, USA), respectively. After 2 washes, dead cells were labeled with TO-PRO-3 Iodide (ThermoFisher Scientific) and samples were analyzed on a CytoFLEX flow cytometer (Beckman Coulter, Brea, CA, USA) or Novocyte flow cytometer (ACEA Biosciences, San Diego, CA, USA). The median fluorescence intensities (MFIs) at each dilution were plotted and cell ECso’s were derived using a 4-parameter binding model in Prism (GraphPad, La Jolla, CA, USA). Figures 19A and 19B exhibit the binding curves of anti-TF antibodies and anti-TF ADCs, respectively. Figure 19C lists the reportable cell ECso’s and their 95% confidence intervals of the anti-TF antibodies and ADCs.
[00793] As shown in Figures 19A, 19B, and 19C, the cell binding properties of TF- specific ADCs are comparable to the cell binding properties of TF-specific antibodies, which indicates that the conjugation process of ADC did not alter the cell-binding properties of the TF-specific antibody moiety of the ADC.
Example 23: Cytotoxicity Assays of Antibody-Drug Conjugates (ADCs)
[00794] To evaluate ADC cytotoxicity, A43 lcells were plated in 384-well plates (Greiner Bio-One). Anti-TF antibodies conjugated to MC-vc-PAB-MMAE were serially diluted as shown. The TF-specific ADCs were added to A431 cells, with either a 72 h incubation or a 4 h incubation followed by removal of excess ADC and culture for another 68 h. A431 cells were lysed in CTG assay reagent after treatment. CTG luminescence was measured and the mean and standard deviation of 4 replicates graphed in Prism. For each ADC, the ICso and its associated 95% confidence interval were calculated in Prism using a 4-parameter binding model. [00795] Figure 20A shows the cell viability after titrations of anti-TF ADCs with a continuous 72 h incubation. Figure 20B shows the cell viability after titrations of anti-TF ADCs with a 4 h incubation followed by removal of excess ADC and culture for another 68 h. Figure 20C shows the reportable ICso values of ADCs under both the continuous treatment and the pulse treatment. The 95 % confidence intervals for the ICso’s of the continuous treatment and the pulse treatment are listed in Table 46 and Table 47 respectively.
[00796] Both treatments resulted in efficacious cell killing, with a 2.4 to 4.7-fold increase in IC50 when excess ADC was removed from the culture after the 4 h incubation compared to the 72 h incubation. Removal of excess 25 A3 and 39A ADC had the smallest impact on IC50, with a 2.7 and 2.4-fold increase from 0.07 and 0.05 nM, respectively.
[00797] These results indicate that similar to the TF-specific antibodies, the TF-specific ADCs undergo substantial cellular internalization.
Example 24: Cytotoxicity Assays in the Presence of FVIIa
[00798] To understand whether FVIIa interfered with the activity of the TF-specific ADC, we treated A431 cells for 4 h with the TF-specific ADCs (anti-TF antibodies conjugated to MC-vc-PAB-MMAE) in the absence or presence of FVIIa and measured cell viability 68 h later. A431 cells were pre-incubated for 30 min without or with 50 nM of FVIIa prior to the addition of an anti-TF ADC titration. Cell viability was determined by CTG assay. The mean and standard deviation of 4 replicates were graphed in Prism. For each ADC, the IC50 were calculated in Prism using a 4-parameter binding model.
[00799] The cell viability after titrations of anti-TF ADCs in the absence or presence of FVIIa is shown in Figures 21A and 21B respectively. The reportable IC50 values of ADCs in the absence or presence of FVIIa are listed in Figure 21C.
[00800] While the ADCs that competed with FVIIa (29E, 39A, 54E and TF-011) were negatively affected by the presence of FVIIa by at least 2.3-fold, the ADCs that did not compete with FVIIa (group 25 and 43 antibodies) were equally efficacious in the absence or presence of FVIIa.
[00801] These results indicate that FVIIa does not interfere with the activity of anti-TF ADCs from groups 25 and 43.
Example 25: Cytotoxicity Assays on Additional Cancer Cell Lines
[00802] To evaluate TF copy number on the cell surface of different cell lines, l.2xl05 cells were harvested and incubated with 133 nM of anti-human TF antibody 5G9 on a mouse IgG2a backbone for 2 hr on ice. After 2 washes, QIFIKIT beads (Agilent) and cells labeled with anti-TF antibody were incubated for 30 min on ice with 150 nM of Goat Phycoerythrin (PE) F(ab’)2 fragment goat anti-mouse IgG, Fc-gamma fragment specific (Jackson
ImmunoResearch). After 2 washes, dead cells were labeled with TO-PRO-3 Iodide
(ThermoFisher Scientific) and samples were analyzed on a CytoFLEX flow cytometer (Beckman Coulter). After gating for single live cells, the MFFs were determined using FlowJo (Flowjo, Ashland, OR, EISA). A standard curve using QIFIKIT beads was generated in Prism using a 5-parameter binding model to determine copy number. The lower limit of quantitation was l.9xl03 antibody binding sites (also referred to as copy number) and the upper limit of quantitation was 8.0xl05 antibody binding sites.
[00803] The TF copy number on A431, CHO, HCT-l 16, HPAF-II, MDA-MB-231, and RF/6A is listed in Figure 22A. The level of surface TF ranged from l.9xl05 to 5.7xl05 copies in A431, MDA-MB-231 and HPAF-II cells. HCT-l 16 cells expressed 2.2xl04 copies of surface TF and TF expression in CHO cells was below limit of quantitation (BLOQ). As 5G9 cross-reacts with Macaca fascicularis TF and the TF protein sequence between M. fascicularis and mulatta is identical, the level of surface TF in theM mulatta cell line RF/6A was also qualtified (l.7xl04 copies).
[00804] Cell viability of HCT- 116, CHO, MDA-MB-231 , and HPAF-II cells in the presence of titrations of anti-TF MMAE ADCs was shown in Figures 22B, 22C, 22D, and 22E respectively.
[00805] The TF-specific ADCs effectively reduced the viability of MDA-MB-231 and HPAF-II cancer cell lines (Figures 22D and 22E). Compared to the activity on MDA-MB- 231 and HPAF-II cells, the ADCs were less efficacious on HCT-l 16 cells, with some activity at the highest concentration and no reportable ICso value (Figures 22B). The TF-specific ADCs did not affect the viability of the CHO cultures (Figures 22C).
[00806] These results indicate that the cytotoxicity of anti-TF ADCs is specific for TF positive cells.
[00807] When ranking the cell-killing efficacy of the ADCs on A431, HPAF-II and MDA- MB-231 cells, the top four ADCs in descending order were 39A, 29E, 25G1 and 25A3
(Table 46). When A431 cells were incubated for 4 h with the TF-specific ADCs followed by a washout, the top four ADCs in descending order were 39A, 25G1, 25A3 and 29E (Table 47). Thus, the top 2 ranking ADCs with no impact on coagulation were 25G1 and 25 A3. Example 26: Intracellular Microtubule Network in the Presence of Antibody- Drug Conjugates (ADCs)
[00808] Immunofluorescence of the intracellular microtubule network of cells was conducted to illustrate the mechanism of action of the ADC. See Theunissen et al., Methods Enzymol , 2006, 409:251-284. Briefly, A431 or HP F-II cells were seeded onto 8-well poly- D-lysine treated slides (Coming Inc, Corning, NY, USA). One day later, the culture medium was replaced with medium containing ADC at 5 nM. After twenty hours of ADC exposure, the cells were fixed for 15 min at room temperature with 4 % paraformaldehyde
(ThermoFisher Scientific). After three washes with PBS, the cells were permeabilized for 1 h with PBS containing 0.3 % Triton X-100 and 5 % normal goat serum. Next, the microtubule networks were stained for 3 h with anti -tubulin (11H10) rabbit mAh (Alexa Fluor 488 conjugate) (Cell Signaling Technology, Danvers, MA, USA) in PBS containing 1 % BSA and 0.3 % Triton X-100. After three washes, ProLong Gold Antifade reagent with DAPI
(ThermoFisher Scientific) was added to the cells and the slide was mounted for microscopy by using a 0.17 mm coverslip. Image acquisition was conducted on a DMi8 fluorescence microscope (Leica Microsystems, Buffalo Grove, IL, USA) equipped with a sCMOS camera. The Leica LAS X software was used to acquire a system-optimized Z-stack of 6 to 7 microns. A sharp two-dimensional image from this Z-stack was created automatically with the extended depth of field (EDF) image feature. Representative images of tubulin staining of A431 or HPAF-II cells are shown in Figures 23A and 23B respectively.
[00809] While the isotype control ADC did not affect the microtubule network, the 25A3 ADC disrupted the microtubule network effectively in both A431 and HPAF-II cells.
[00810] These results indicate the MMAE-based anti-TF ADCs induce cytotoxicity in TF- positive cancer cells through disruption of the intracellular microtubule network.
Example 27: Cytotoxicity Assays and G2/M arrest in HUVECs
[00811] To evaluate TF copy number on the cell surface of human umbilical vein endothelial cells (HUVECs), L2xl05 HUVECs were harvested and incubated with 133 nM of anti-human TF antibody 5G9 on a mouse IgG2a backbone for 2 hr on ice. After 2 washes, QIFIKIT beads (Agilent) and cells labeled with anti-TF antibody were incubated for 30 min on ice with 150 nM of Goat Phycoerythrin (PE) F(ab’)2 fragment goat anti-mouse IgG, Fc- gamma fragment specific (Jackson ImmunoResearch). After 2 washes, dead cells were labeled with TO-PRO-3 Iodide (ThermoFisher Scientific) and samples were analyzed on a CytoFLEX flow cytometer (Beckman Coulter). After gating for single live cells, the MFFs were determined using FlowJo (Flowjo, Ashland, OR, USA). A standard curve using QIFIKIT beads was generated in Prism using a 5-parameter binding model to determine copy number. The lower limit of quantitation was l.9xl03 antibody binding sites (also referred to as copy number) and the upper limit of quantitation was 8.0xl05 antibody binding sites.
[00812] In response to injury, inflammatory and angiogenic factors transiently increase expression of surface TF in the vasculature. See Holy et al., Adv Pharmacol, 2010, 59:259- 592, which is incorporated by reference in its entirety. The transient upregulation of TF in cell culture was mimicked by treating HUVECs with a combination of inflammatory cytokines (5 ng/mL ILl-beta, 25 ng/mL TNF-alpha and 50 ng/mL VEGF). As shown in
Figure 24A, surface TF levels increased from 2.4xl03 copies in the absence of inflammatory cytokines to l.2xl04 copies after 6 h of cytokine treatment. The surface TF was ~3-fold lower after 20 h of cytokine treatment relative to 6 h of treatment, which indicates that the cytokine- induced TF upregulation was transient.
[00813] For the ADC cytotoxicity assay, HUVEC cultures were seeded on half-area 96- well plates. The next day, the combination of inflammatory cytokines and a titration of ADCs was added to the cultures. Four days later viability of the cultures was assessed by lysis in CellTiter-Glo (CTG) assay reagent. As shown in Figure 24B, the cell viability of
inflammatory cytokine-treated HUVEC cultures was unaffected by the anti-TF ADCs, 25 A- vc-MMAE and 43Ea-vc-MMAE. The results indicates that the inflammatory cytokine-treated endothelial cells are resistant to anti-TF ADCs.
[00814] To further understand the resistance of endothelial cells to anti-TF ADCs, cell cycle progression was evaluated 24 h after addition of the cytokines and TF-specific ADCs. Arrest at the the G2/M phase of the cell cycle was analyzed as previously described in Theunissen et al , Methods Enzymol, 2006, 409:251-284. Briefly, low-passage HUVECs (Lifeline Cell Technologies, Frederick, MD, USA), propagated in VascuLife VEGF-Mv Endothelial media (Lifeline Cell Technologies), and HCT-l 16 cells were seeded on l2-well plates. The next day, media was removed and replaced with fresh media (no cytokines) or media containing 5 ng/mL ILl-beta, 25 ng/mL TNF-alpha and 50 ng/mL VEGF (with cytokines). A titration of MMAE-linked ADCs or free MMAE was added to the cells. After 24 h of treatment, cells were fixed in ice-cold 70 % ethanol. Subsequently, the cells were washed with flow cytometry buffer (PBS, 1 % FBS, 0.1 % Triton) and stained for 1 h with a 1 : 100 dilution of phospho-Hi stone H3 (SerlO) (D2C8 PE Conjugate, Cell Signaling
Technology). After 2 washes, the cells were treated for 20 min with 100 pg/mL PureLink RNAse A (ThermoFisher Scientific), followed by the addition of the viability dye TO-PRO-3 Iodide (ThermoFisher Scientific). 40,000 events were collected on a Novocyte flow cytometer. In the Flowjo data analysis software cell doublets and aneuploid cells were excluded. The pH3 signal was plotted against DNA content to determine the percentage of pH3 -positive cells.
[00815] The percentage of pH3-positive cells (% pH3) with titrations of anti-TF ADCs on FtUVECs in the absence or presence of inflammatory cytokines is shown in Figures 25A and 25B respectively. The percentage of pFB-positive cells (% pH3) with titrations of anti-TF ADCs on HCT-l 16 cells is shown in Figure 25C.
[00816] While the TF-specific ADCs induced an arrest at the G2/M phase of the cell cycle in HCT-l 16 cells, the ADCs did not impact cell cycle progression in FtUVECs with or without inflammatory cytokine treatment. As shown in Figures 26A and 26B, the percentage of pH3-positive HCT-l 16 cells increased 5 times after treatment of 25A-vc-MMAE as compared to treatment of Isotype-vc-MMAE.
[00817] Figures 27A and 27B show that unconjugated MMAE increase the
phosphorylation of histone H3 to a similar extent in both HCT-l 16 cells and FtUVECs, indicating that the resistance in endothelial cells is specific for the MMAE-based ADC.
[00818] Taken together, these results indicate that the anti-TF ADCs do not affect the viability of FtUVECs in the absence or presence of inflammatory cytokines.
Example 28: Erk Phosphorylation Assay
[00819] For assessment of Erk phosphorylation, A431 cells were plated in 6-well plates (Corning) in media overnight. The following day, cells were washed once and serum starved in serum-free media. After starvation, cells were preincubated with 100 nM of anti-TF antibodies for 30 min at 37 °C. FVIIa was spiked into the wells at 50 nM and incubated for 20 min at 37 °C for p-ERK induction. After induction, cells were lysed with RIPA Lysis and Extraction Buffer with Halt™ Protease and Phosphatase Inhibitor Cocktail (ThermoFisher Scientific). Western blot was performed with 20 pg of cell lysate using Phospho-p44/42 MAPK (Erk 1/2) (Thr202/Tyr204) and p44/42 MAPK (Erkl/2) (137F5) (Cell Signaling Technology) as primary antibodies and Peroxidase AffmiPure Donkey Anti -Rabbit IgG (H+L) (Jackson ImmunoResearch) as a secondary antibody. Non-saturating band intensities for pErk and Erk were measured on an Amersham AI600 (GE Healthcare). Each pErk intensity was normalized against its respective Erk intensity and the no-antibody no-FVIIa sample intensity.
[00820] The Western blot results of pErk and Erk are shown in Figure 28. Treatment with FVIIa induced Erk phosphorylation by 5.2 fold in cell cultures without pretreatment of anti- TF antibodies. The inducation of Erk phosphorylation was ablated by pretreatment with 1F, 39A and 54E (fold induction between 0.8 and 1.2) and attenuated by 29E and the members of groups 25 and 43 (fold induction between 2.0 and 3.4).
[00821] This data indicates that anti-TF antibodies inhibit FVIIa-dependent TF signaling when assessing Erk phosphorylation.
Example 29: Antibody-Dependent Cellular Cytotoxicity (ADCC) Assay
[00822] To evaluate ADCC activity, an ADCC Reporter Bioassay Core Kit (Promega) was used following the manufacturer’s protocol. Briefly, A431 cells were plated on a microtiter plate (Coming). The following day, the cells were incubated with a ten-point 1 :3 dilution titration of anti-TF antibodies or the ADCs starting at 50 nM. An ADCC effector-to-target cell ratio of 8: 1 was added to each well and incubated for 6 h at 37 °C. Bio-Glo™ Luciferase Assay Reagent was added to each well to measure luminescence on an Envision plate reader (PerkinElmer, Waltham, MA, EISA). The mean and standard deviation of 4 replicates were graphed in Prism. For each antibody and ADC, the ECso and its associated 95 % confidence interval were calculated in Prism using a 4-parameter binding model.
[00823] ADCC reporter luminescence after incubation with the reporter Jurkat cell line in the represece titrations of anti-TF antibodies or anti-TF ADCs is shown in Figures 29A and 29B respectively. The ADCC reporter luminescence ECso values for each anti-TF antibody or ADC are listed in Figure 29C.
[00824] All the tested TF-specific antibodies and ADCs exerted induction of luciferase- dependent luminescence with ECso values ranging between 0.18 and 0.43 nM.
[00825] These data indicate that both the TF-specific antibodies and ADCs can induce antibody-dependent cellular cytotoxicity (ADCC) via the IgGl Fc domain of the antibody.
Example 30: Studies in Cell Line-Derived Xenograft (CDX) Models
[00826] To evaluate the efficacy of the ADCs in vivo, xenograft studies in immune compromised mice were performed as described in Kim et ak, Blood Cancer J, 2015, 5:e3 l6, which is incorporated by reference in its entirety. Briefly, the A431 epidermoid carcinoma and the HPAF-II pancreatic carcinoma cell lines were implanted subcutaneously in the flank of athymic nude mice (Charles River Laboratories, Wilmington, MA). Animals were randomized and treated as indicated in the figures. Body weight and tumor size assessments were performed bi-weekly. Animals were removed from study and euthanized once tumor size reached 1200mm3 or skin ulceration was evident. In addition, the MTV curve for the treatment group in question was no longer shown once an animal was removed from study due to size. The animals’ care was in accordance with institutional guidelines. Mean tumor volume (MTV) with the standard error of the mean (SEM) was plotted over time. Treatment efficacy was determined by calculating tumor growth inhibition (% TGI = 100 % x [1 -(final MTV - initial MTV of a treated group) / (final MTV - initial MTV of the control group)]) before any of the animals in the vehicle arm were euthanized due to a tumor size > l200mm3. Statistical comparisons between the MTVs were conducted using one-way ANOVA followed by Tukey’s multiple comparisons test comparing all groups. The /’-values for each ADC compared to the vehicle control arm are reported. At the end of the study, efficacy was also determined in each treatment arm by counting the number of animals with a partial regression (PR) or a complete regression (CR) of the tumor. In a PR response, the tumor volume was 50 % or less of its day 1 volume for 3 consecutive measurements during the course of study, and equal to or greater than l4mm3 for 1 or more of these measurements. In a CR response, the tumor volume was less than l4mm3 for 3 consecutive measurements. When an animal exhibited a CR response at the end of the study, it was classified as a tumor-free survivor (TFS) instead of a CR. Throughout the ADC studies no significant body weight changes due to ADC treatment were observed.
[00827] As shown in Figure 30A, HPAF-II tumor-bearing mice were treated with 5 mg/kg of ADC on day 1, 8 and 15 after randomization. The effect of TF-011 ADC was compared with two representative clones from the two groups that did not impact coagulation (i.e. 25 A and 43Ea). Twenty-one days after randomization the efficacy of the 25 A, 43Ea and TF-011 ADCs was equivalent, with tumor growth inhibition ranging between 131 and 136 %.
[00828] In the second HPAF-II study as shown in Figure 30B, the highest affinity antibody that affected coagulation (i.e. 39A) and six antibodies with varying affinities from groups 25 and 43 (i.e. 25A, 25A3, 25G1, 43Ea, 43B1 and 43D7) were equally efficacious when dosed twice at 2 mg/kg. Tumor growth inhibition for the TF-specific ADCs ranged between 129 and 139 % on day 21, and 6 to 9 out of 10 animals per treatment arm were classified as tumor-free survivors at the end of the study.
[00829] In the MDA-MB-231 xenograft model, the ADCs were administered on day 1 and 8 post-randomization at 4 or 2 mg/kg. As shown in Figure 31A, all the TF-specific ADCs were active at 4 mg/kg, with tumor growth inhibition ranging between 69 and 100 %, and a significant difference in mean tumor volume for each TF-specific ADC compared to the vehicle control arm. While a notable difference was observed in mean tumor volume between 25G1 and the other TF-specific ADCs, it was not statistically significant ( P > 0.05). [00830] At 2 mg/kg of ADC as shown in Figure 31B, all the TF-specific antibodies showed suboptimal activity with varying degrees of significance in mean tumor volume compared to the vehicle control arm. 25 A3, 39A and 43B1 showed the greatest degree of significance in mean tumor volume compared to the vehicle control arm ( P < lxlO-4). The difference in mean tumor volume between 39A and the other antibodies was only significant for the comparison between 39A and 43Ea ( P < 0.05).
[00831] In contrast, the unconjugated antibodies of 25A, 25A3 and 43Ea lacked substantial anticancer activity when dosed twice at 10 mg/kg in the HPAF-II xenograft model
(Figure 32).
[00832] There results indicate that the TF-specific ADCs are efficacious in the HPAF-II and MDA-MB-231 xenograft model under various dosing regimens. The activity of the ADCs are caused by the toxin delivery of the anti-TF antibodies.
Example 31: Studies in Patient-Derived Xenograft (PDX) Models
[00833] TF-positive PDX models were performed in athymic nude mice (Envigo,
Indianapolis, IN) to evaluate the efficacy of the ADCs in vivo. The animals’ care was in accordance with institutional guidelines. Study animals were implanted unilaterally on the left flank with tumor fragments.
[00834] For immunohistochemistry (IHC) analysis, tissues underwent pretreatment using Rip Tide (Mosaic Laboratories, Lake Forest, CA) for 40 min at 95-97 °C in a water bath, cooled for 10 min on the bench, rinsed 3 times with distilled water, and rinsed for 5 min with Splash-T Buffer (Mosaic Laboratories). Tissue sections were blocked in EnVision
Peroxidase-Blocking Reagent (EnVision+ Mouse HRP Detection Kit, Agilent, Carpinteria, CA) for 5 min, followed by 2 rinses in Splash-T Buffer for 5 min each. Next, the tissue sections were stained with an anti-TF antibody (mouse clone HTF-l) or a mouse negative control reagent for 30 min, followed by 2 rinses in Splash-T Buffer for 5 min each. The second staining step of the tissue sections was carried out for 30 min with EnVision+ Mouse HRP (EnVision+ Mouse HRP Detection Kit), followed by 2 rinses in Splash-T Buffer for 5 min each. To visualize the anti-TF staining, tissue sections were developed with DAB chromogen (EnVision+ Mouse HRP Detection Kit) for 5 min, followed by 10 dips and a 5 min rinse in distilled water. Tissue sections were counterstained with Hematoxylin for 5 min followed by 3 rinses in distilled water.
[00835] Animals were randomized and treated as indicated in the figures. Animals were removed from study and euthanized once tumor size reached 1200mm3 or skin ulceration was evident. In addition, the MTV curve for the treatment group in question was no longer shown once an animal was removed from study due to size. TGI and statistical analyses were conducted in the same manner as for the CDX studies. The CR and PR response definitions were as follows for the PDX studies: a PR responder had a MTV < 30 % of MTV at day 1 for 2 consecutive measurements; a CR responder had an undetectable MTV for 2 consecutive measurements. When an animal exhibited a CR response at the end of the study, it was classified as a TFS instead of a CR.
[00836] While the squamous cell carcinoma of the head and neck (SCCHN) and ovarian adenocarcinoma PDX had H-scores of 250 and 220, respectively, the gastric adenocarcinoma PDX had an H-score of 155 (data not shown). Upon randomization of tumor-bearing mice, treatment occurred on a weekly basis either twice or three times with the dose ranging between 2.5 and 5 mg/kg. As shown in Figures 33 A, 33B, and 33C in all the PDX models a significant reduction in mean tumor volume was observed for each TF-specific ADC compared to the isotype control arm ( P < lxlO-4), with no significant difference between the various TF-specific ADCs ( P > 0.05). In the head and neck and ovarian PDX model, the number of complete responders and tumor-free survivors did not exceed 2 out of 10 animals at the end of the study in any of the treatment groups (Figures 33A and 33B). However, in the gastric PDX the 25 A treatment arm had 2 partial responders, 2 complete responders and 3 tumor-free survivors, and the TF-011 arm contained 1 complete responder and 5 tumor-free survivors at the end of the study (Figure 33C).
[00837] These data indicate that the anti-TF ADCs from groups 25 and 43 (i.e. 25A and 43Ea) were equally efficacious as tisotumab vedotin (TF-011) ADC.
Example 32: Efficacy Study in Swine CNV Model
[00838] An efficacy study in a swine choroidal neovascularization (CNV) model was performed to determine the effect 4 different anti-TF antibodies in reducing lesion size.
[00839] 10-12 week old animals (Swine/Hampshire Cross) underwent bilateral laser using an 810 nm Diode laser delivered through an indirect ophthalmoscope to create approximately 6 single laser spots between retinal veins in each eye of each animal. For efficacy
assessments, 2mg of each anti-TF antibody, 25G9, 43D8, 1G, and 29D respectively, were administered intravitreally on day 7 post-laser treatment. A vehicle control group was also included in the study. Fluorescein Angiography (FA) to determine total lesion fluorescence was performed on day 7 (baseline), day 14 and day 28. FA was evaluated using a Corrected Total Lesion Fluorescence (CTLF) measurement for each individual lesion. The perimeter of the lesion was traced, and an integrated density value was obtained. CTLF was then calculated by subtracting the mean fluorescence background adjacent to the lesion from the integrated density measurement. Percent change in lesion size from day 7 to day 14 and from day 7 to day 28 are shown in Figure 34A and Figure 34B, respectively.
[00840] From day 7 to day 14, anti-hTF antibodies from groups 25 and 43, 25G9 and 43D8, reduced lesion size by greater than 20%. From day 7 to day 28, anti-hTF antibody 25G9 reduced lesion size by greater than 40%. Anti-hTF antibodies 1G and 29D did not reduce lesion size significantly as compared to the vehicle control group.
[00841] This data indicates that antibodies from groups 25 and 43, 25G9 and 43D8, were effective in reducing lesion size in a swine CNV model.
Example 33: Efficacy of 25G9 in Swine CNV Model
[00842] An efficacy study in a swine choroidal neovascularization (CNV) model was performed to compare different doses of anti-TF antibody 25G9 for their ability to reduce lesion size.
[00843] 10-12 week old animals (Swine/Hampshire Cross) underwent bilateral laser using an 810 nm Diode laser delivered through an indirect ophthalmoscope to create approximately 6 single laser spots between retinal veins in each eye. For efficacy assessments 600ug, 2mg and 4mg of anti-TF antibody 25G9 were administered intravitreally on Day 7 post-laser treatment. Fluorescein Angiography (FA) to determine total lesion fluorescence was performed on day 7 (baseline) and day 28. FA was evaluated using a Corrected Total Lesion Fluorescence (CTLF) measurement for each individual lesion. The perimeter of the lesion was traced, and an integrated density value was obtained. CTLF was then calculated by subtracting the mean fluorescence background adjacent to the lesion from the integrated density measurement. Percent changes in lesion size from day 7 to day 28 are shown in Figure 35.
[00844] From day 7 to day 28, anti-hTF antibody 25G9 reduced lesion size in a dose- depenent matter. 25G9 reduced lesion size by greater than 50% at 4mg. This data indicates that antibody 25G9 was effective in reducing lesion size in the swine CNV model in a dose- dependent matter.
Example 34: Binding Affinity Assay For Pig TF and Rabbit TF
[00845] The ability of certain antibodies was tested for binding to pig TF. For pig TF Biacore-based measurements, a given anti-TF antibody was captured by an anti-human IgG antibody covalently coupled to a CM5 chip (GE Healthcare Bio-Sciences). Association between the anti-TF antibodies and a five-point three-fold titration of pig TF-His starting at 100 nM was measured for 180 to 240 sec. Subsequently, dissociation between the anti-TF antibody and TF-His was measured for 1800 sec. Kinetic data was analyzed and fitted globally using a 1 : 1 binding model. The KD values of the indicated TF antibodies measured by the Biacore-based experiments are shown in Table 48.
[00846] The ability of certain antibodies was tested for binding to rabbit TF. For rabbit TF Biacore-based measurements, a given anti-TF antibody was captured by an anti-human IgG antibody covalently coupled to a CM5 chip (GE Healthcare Bio-Sciences). Association between the anti-TF antibodies and a five-point three-fold titration of rabbit TF-His starting at 100 nM was measured for 180 to 240 sec. Subsequently, dissociation between the anti-TF antibody and TF-His was measured for 1800 sec. Kinetic data was analyzed and fitted globally using a 1 : 1 binding model. The KD values of the indicated TF antibodies measured by the Biacore-based experiments are shown in Table 48.
[00847] As shown in Table 48, anti-hTF antibodies from groups 25 and 43 exhibit binding activity and cross-reactivity to pig TF and rabbit TF. In contrast, antibodies from groups 1 and 29 show no binding activity to pig TF or rabbit TF.

Example 35: Immunohistochemistry (IHC) Assay
[00848] Tissues underwent pretreatment using Rip Tide (Mosaic Laboratories, Lake Forest, CA) for 40 min at 95-97 °C in a water bath, cooled for 10 min on the bench, rinsed 3 times with distilled water, and rinsed for 5 min with Splash-T Buffer (Mosaic Laboratories). Tissue sections were blocked in EnVision Peroxidase-Blocking Reagent (EnVision+ Mouse HRP Detection Kit, Agilent, Carpinteria, CA) for 5 min, followed by 2 rinses in Splash-T Buffer for 5 min each. The tissue sections were then stained with an anti-TF antibody (mouse clone HTF-l) or a mouse negative control reagent for 30 min, followed by 2 rinses in Splash- T Buffer for 5 min each. The second staining step of the tissue sections was carried out for 30 min with EnVision+ Mouse HRP (EnVision+ Mouse HRP Detection Kit), followed by 2 rinses in Splash-T Buffer for 5 min each. To visualize the anti-TF staining, tissue sections were developed with DAB chromogen (EnVision+ Mouse HRP Detection Kit) for 5 min, followed by 10 dips and a 5 min rinse in distilled water. Tissue sections were counterstained with Hematoxylin for 5 min followed by 3 rinses in distilled water.
[00849] Staining intensity was scored on a semi-quantitative integer scale from 0
(negative) to 3 (or“3+”) by a certified anatomic pathologist. The percentage of cells staining positively at each intensity level was recorded. Scoring was based on localization of TF to the cell membrane. The H score combines components of staining intensity with the percentage of positive cells. It has a value between 0 and 300 and is defined as: 1 c (percentage of cells staining at 1+ intensity) + 2 x (percentage of cells staining at 2+ intensity) + 3 x (percentage of cells staining at 3+ intensity) = H score.
[00850] Tissue sections from patients with kidney cancer, head & neck cancer, ovarian cancer, gastric cancer, prostate cancer, gastroesophageal junction cancer, cervical cancer, and glioblastoma were stained. The number of patients with scores within each H score range and the total number of patient for each cancer are shown in Table 50. These results indicate that TF is expressed in kidney cancer, head & neck cancer, ovarian cancer, gastric cancer, prostate cancer, gastroesophageal junction cancer, cervical cancer, and glioblastoma.

Example 36: Epitope Binning of Anti-TF Antibodies
[00851] To establish epitope binding differences between the anti-human TF antibodies, chimeric TF construct mapping experiments were conducted. This mapping technique enables discrimination of antibody epitopes.
[00852] Because all the anti-human TF antibodies evaluated do not bind rat TF, the rat TF sequence was used for the construction of chimeric human-rat TF constructs. Chimeric human-rat construct design was guided by the N- and C-terminal domain of TF extracellular domain (amino acids 1 - 107 and 108 - 219 of the extracellular domain, respectively), with an alignment shown in Figure 36. Based on the chimera mapping results using the constructs from Figure 36, rat amino acid segment 141 - 194 was replaced by the human sequence (amino acid 136 - 189 of hTF extracelluar domain), with an alignment shown in Figure 37. Design of three human TF constructs with either 1 or 2 human-rat substitutions (hTF_K68N, hTF_KT49N and hTF_Nl7lH_Tl97K) was based on reported contact residues K68, K149 and Nl7l and T197 for the 10H10 antibody (Teplyakov et al., Cell Signal., 2017, 36:139- 144), with an alignment shown in Figure 38.
[00853] To establish binding of the anti-human TF antibodies to the various TF constructs, HEK293 cells were transfected with a DNA plasmid that co-expresses the TF construct and a green fluorescent protein marker. For a subset of the antibodies, an antibody titration (a 12- point 1 :3 dilution series starting at 250 nM) was evaluated on select TF constructs (Figures 39A-F). These antibody titrations demonstrated that the antibody concentration of 15 pg /ml (100 nM) used in Tables 51 and 52 was appropriate to establish“Percentage antibody binding to TF construct relative to hTF”. Two days after transfection, cells were collected from the tissue culture plate, stained with 15 pg/ml of the indicated anti-TF antibody, washed, stained with anti -human IgG-Fc Alexa Fluor 647 polyclonal antibody, washed, and stained with the viability dye 4',6-Diamidino-2-Phenylindole, Dihydrochloride. Upon acquisition of 80,000 live events on a flow cytometer, live cells marked with the fluorescent marker were analyzed for the degree of staining by the anti-TF antibody. The median fluorescence intensity values relative to an isotype control for each TF expression construct were divided by the median fluorescence intensity value relative to an isotype control for the hTF expression construct, and the resulting percentage listed as“Percentage antibody binding to TF construct relative to hTF” in Tables 51 and 52. As used herein, the term“live cell staining assay” refers to the antibody binding assay used in this example.
[00854] The assumption that all chimeric TF constructs were expressed on the cell surface at levels between 50% and 150% of the hTF control construct was met for all TF constructs for at least one anti-human TF antibody in the antibody collection, with the exception of the hl-l07_r construct (human amino acid segment 1-107 replaced by rat sequence). Lack of binding of the anti-human TF antibodies to cell surface-expressed rat TF was expected. When “Percentage antibody binding to TF construct relative to hTF” in Tables 51 and 52 was less than 50%, the antibody was considered a non-binder (0) in Tables 53 and 54. When “Percentage antibody binding to TF construct relative to hTF” in Tables 51 and 52 was between 50% and 150%, the antibody was considered a binder (1) in Tables 53 and 54.
[00855] Each antibody was assigned to an epitope bin in Table 55 based on the combination of unbound constructs from Table 53. The antibodies from Lineage 25 (25A, 25A3, 25A5-T, 25G1 and 25G9) bind a unique epitope, referred to as Epitope Bin 6 in Table 55. The antibodies from Lineage 43 (43B1, 43D7, 43D8 and 43Ea) also bind a unique epitope, referred to as Epitope Bin 7 in Table 55. The antibody from Lineage 29 (29E) binds a unique epitope, referred to as Epitope Bin 2 in Table 55. The antibodies from Lineage 39 and 54 (39A and 54E) bind a unique epitope, referred to as Epitope Bin 3 in Table 55.
[00856] Lineage 25 and 43 antibodies are the only antibodies in the antibody panel that bind rl4l-l94_h, the chimeric construct in which rat amino acids 141-194 were replaced by human sequence (Figure 39F; Table 54). Furthermore, while M1593 cannot bind
hTF_K68N, all the other antibodies in the antibody panel bind hTF_K68N (Figure 39C; Table 54). Only Lineage 25 and 43 antibodies cannot bind hTF_KT49N (Figure 39D; Table 54). Only Lineage 25 antibodies cannot bind hTF_Nl7lH_Tl97K (Figure 39E; Table 54).
[00857] In summary, these results indicate that lineage 25 antibodies bind a unique epitope on human TF compared to all other antibodies tested. Lineage 43 antibodies bind a unique epitope on human TF compared to all other antibodies tested. Lineage 25 and lineage 43 antibodies bind a different epitope on human TF from Ml 593.
