This application incorporates by reference the computer readable sequence listing entitled “108843.00462 Sequence Listing” created Jul. 30, 2023 having 1.29 MB.
Provided herein are antibodies and antibody conjugates, for instance antibody drug conjugates, with binding specificity for receptor tyrosine kinase orphan receptor 1 (ROR1) and compositions comprising the antibodies or antibody conjugates, including pharmaceutical compositions. Also provided herein are methods of producing the antibodies and conjugates, and methods of using the antibodies or conjugates and compositions for therapy. The antibodies, conjugates, and compositions are useful in methods of treatment and prevention of cell proliferation and cancer, for example, by activating anti-tumor immunity; methods of detection of cell proliferation and cancer; and methods of diagnosis of cell proliferation and cancer. The antibodies, conjugates, and compositions are also useful in methods of treatment, prevention, detection, and diagnosis of autoimmune diseases, infectious diseases, and inflammatory conditions.
Receptor tyrosine kinase-like orphan receptor (ROR1) is a member of the receptor tyrosine kinases (RTK) family. OMIM entry 602336. Receptor tyrosine kinases function as cell surface receptors, and they have been postulated to play roles in the control of cell proliferation, differentiation, migration, and metabolism. Afzal & Jeffery, 2003, Hum. Mutat. 22:1-11. Based on conserved sequences from other receptor tyrosine kinases, ROR1 was initially identified in 1992. Masiakowski & Carroll, 1992, J. Biol. Chem. 267:26181-26190. The ROR1 gene encodes a type I glycosylated membrane protein with a predicted length of 937 amino acids. See id.; Entrez Gene ID. 4919. The ROR1 gene has been mapped to chromosome 1p32-p31. Reddy et al., 1997, Genomics 41: 283-285. Expression of ROR1 has been observed in human heart, lung, and kidney, and also weakly in the central nervous system. Reddy et al. Truncated expression was observed in a variety of human cancers, including those originating from CNS or PNS neuroectoderm. Reddy, 1996, Oncogene 13:1555-1559. ROR1 knockout mice had no obvious skeletal or cardiac abnormalities, yet they died soon after birth due to respiratory dysfunction. Nomi et al., 2001, Molec. Cell. Biol. 21:8329-8335.
ROR1 has recently been shown to be expressed on cancer cells, including ovarian cancer cells, and on cancer stem cells. Zhang et al., 2014, Proc. Natl. Acad. Sci. USA 111:17266-71. Treatment with a monoclonal antibody specific for ROR1 inhibited development of ovarian cancer cells, and ROR1 has been postulated as a target for cancer therapeutics. See id.
There is a need for improved methods of targeting and/or modulating the activity of ROR1. Given the specific expression of ROR1 in cancer cells and cancer stem cells, there is a need for improved therapeutics that can specifically target cells and tissues that express or overexpress ROR1. Antibody conjugates to ROR1 could be used to deliver therapeutic or diagnostic payload moieties to target cells expressing ROR1 for the treatment or diagnosis of such diseases.

In some embodiments, the antibody conjugates bind human ROR1. In some embodiments, the antibody conjugates also bind homologs of human ROR1. In some aspects, the antibody conjugates also bind homologs of cynomolgus monkey and/or mouse receptor ROR1.
These and other embodiments of the invention along with many of its features are described in more detail in conjunction with the text below and attached figures.
Unless otherwise defined, all terms of art, notations and other scientific terminology used herein are intended to have the meanings commonly understood by those of skill in the art to which this invention pertains. In some cases, terms with commonly understood meanings are defined herein for clarity and/or for ready reference, and the inclusion of such definitions herein should not necessarily be construed to represent a difference over what is generally understood in the art. The techniques and procedures described or referenced herein are generally well understood and commonly employed using conventional methodologies by those skilled in the art, such as, for example, the widely utilized molecular cloning methodologies described in Sambrook et al., Molecular Cloning: A Laboratory Manual 2nd ed. (1989) Cold Spring Harbor Laboratory Press, Cold Spring Harbor, NY. As appropriate, procedures involving the use of commercially available kits and reagents are generally carried out in accordance with manufacturer-defined protocols and conditions unless otherwise noted.
As used herein, the singular forms “a,” “an,” and “the” include the plural referents unless the context clearly indicates otherwise.
The term “about” indicates and encompasses an indicated value and a range above and below that value. In certain embodiments, the term “about” indicates the designated value±10%, ±5%, or ±1%. In certain embodiments, the term “about” indicates the designated value±one standard deviation of that value.
The term “combinations thereof” includes every possible combination of elements to which the term refers to.
The terms “ROR1” and “receptor tyrosine kinase like orphan receptor 1” are used interchangeably herein. ROR1 is also known by synonyms, including NTRKR1 neurotrophic tyrosine kinase, receptor-related 1, and dJ537F10.1, among others. Unless specified otherwise, the terms include any variants, isoforms and species homologs of human ROR1 that are naturally expressed by cells, or that are expressed by cells transfected with a ROR1 or ROR1 gene. ROR1 proteins include, for example, human ROR1 (SEQ ID NO: 1). In some embodiments, ROR1 proteins include cynomolgus monkey ROR1 (SEQ ID NO: 2). In some embodiments, ROR1 proteins include murine ROR1 (SEQ ID NO: 3).
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 CH1, CH2, and CH3. 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.
The term “antibody” describes a type of immunoglobulin molecule and is used herein in its broadest sense. An antibody specifically includes intact antibodies (e.g., intact immunoglobulins), and antibody fragments. Antibodies comprise at least one antigen-binding domain. One example of an antigen-binding domain is an antigen binding domain formed by a VH-VL dimer. A “ROR1 antibody,” “anti-ROR1 antibody,” “ROR1 Ab,” “ROR1-specific antibody,” “anti-ROR1 Ab,” “ROR1 antibody,” “anti-ROR1 antibody,” “ROR1 Ab,” “ROR1-specific antibody,” or “anti-ROR1 Ab” is an antibody, as described herein, which binds specifically to ROR1 or ROR1. In some embodiments, the antibody binds the extracellular domain of ROR1.
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 Kabat 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.
The light chain from any vertebrate species can be assigned to one of two types, called kappa and lambda, based on the sequence of the constant domain.
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 α, δ, ε, γ, and μ, 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: IgG1, IgG2, IgG3, IgG4, IgA1, and IgA2.
The amino acid sequence boundaries of a CDR can be determined by one of skill in the art using any of a number of known numbering schemes, including those described by Kabat et al., supra (“Kabat” numbering scheme); Al-Lazikani et al., 1997, J. Mol. Biol., 273:927-948 (“Chothia” numbering scheme); MacCallum et al., 1996, J. Mol. Biol. 262:732-745 (“Contact” numbering scheme); Lefranc et al., Dev. Comp. Immunol., 2003, 27:55-77 (“IMGT” numbering scheme); and Honegge and Pluckthun, J. Mol. Biol., 2001, 309:657-70 (“AHo” numbering scheme), each of which is incorporated by reference in its entirety.
Table 1 provides the positions of CDR-L1, CDR-L2, CDR-L3, CDR-H1, CDR-H2, and CDR-H3 as identified by the Kabat and Chothia schemes. For CDR-H1, residue numbering is provided using both the Kabat and Chothia numbering schemes.
Unless otherwise specified, the numbering scheme used for identification of a particular CDR herein is the Kabat/Chothia numbering scheme. Where the residues encompassed by these two numbering schemes diverge (e.g., CDR-H1 and/or CDR-H2), the numbering scheme is specified as either Kabat or Chothia. For convenience, CDR-H3 is sometimes referred to herein as either Kabat or Chothia. However, this is not intended to imply differences in sequence where they do not exist, and one of skill in the art can readily confirm whether the sequences are the same or different by examining the sequences.
CDRs may be assigned, for example, using antibody numbering software, such as Abnum, available at www.bioinf.org.uk/abs/abnum/, and described in Abhinandan and Martin, Immunology, 2008, 45:3832-3839, incorporated by reference in its entirety.
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). Unless stated otherwise, the EU numbering scheme is used to refer to residues in antibody heavy chain constant regions described herein.
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.
“Fv” fragments comprise a non-covalently-linked dimer of one heavy chain variable domain and one light chain variable domain.
“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 (CH1) of the heavy chain. Fab fragments may be generated, for example, by recombinant methods or by papain digestion of a full-length antibody.
“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 β-mercaptoethanol.
“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 Plückthun A. (1994). In some embodiments, the linker is SEQ ID NO: 1034. In some embodiments, the linker is SEQ ID NO: 1035. 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.
“scFv-Fc” fragments comprise an scFv attached to an Fc domain. For example, an Fc domain may be attached to the C-terminus 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. In some cases, the Fc domain comprises an IgG1 Fc domain. In some embodiments, the IgG1 Fc domain comprises SEQ ID NO: 1027, or a portion thereof. SEQ ID NO: 1027 provides the sequence of CH1, CH2, and CH3 of the human IgG1 constant region.
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.
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.
“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 immunoglobulin (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 al., Nature, 1986, 321:522-525; Riechmann et al., 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.
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.
An “isolated antibody” is one 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. An isolated antibody includes 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 is prepared by at least one purification step.
In some embodiments, an isolated antibody is purified to at least 80%, 85%, 90%, 95%, or 99% by weight. In some embodiments, an isolated antibody is purified to at least 80%, 85%, 90%, 95%, or 99% by volume. In some embodiments, an isolated antibody is provided as a solution comprising at least 85%, 90%, 95%, 98%, 99% to 100% by weight. In some embodiments, an isolated antibody is provided as a solution comprising at least 85%, 90%, 95%, 98%, 99% to 100% by volume.
“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). Unless indicated otherwise, as used herein, “binding affinity” refers to intrinsic binding affinity, which reflects a 1:1 interaction between members of a binding pair (e.g., antibody and antigen). The affinity of a molecule X for its partner Y can be represented by the dissociation constant (KD). Affinity can be measured by common methods known in the art, including those described herein. Affinity can be determined, for example, using surface plasmon resonance (SPR) technology, such as a Biacore® instrument. In some embodiments, the affinity is determined at 25° C.
With regard to the binding of an antibody to a target molecule, the terms “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. Specific binding can be measured, for example, by determining binding of a molecule compared to binding of a control molecule. Specific binding can also be determined by competition with a control molecule that mimics the antibody binding site on the target. In that case, specific binding is indicated if the binding of the antibody to the target is competitively inhibited by the control molecule.
The term “kd” (sec−), as used herein, refers to the dissociation rate constant of a particular antibody-antigen interaction. This value is also referred to as the koff value.
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 kon value.
The term “KD” (M), as used herein, refers to the dissociation equilibrium constant of a particular antibody-antigen interaction. KD=kd/ka.
The term “KA” (M−1), as used herein, refers to the association equilibrium constant of a particular antibody-antigen interaction. KA=ka/kd.
An “affinity matured” antibody is one with one or more alterations in one or more CDRs or FRs that result in an improvement in the affinity of the antibody for its antigen, compared to a parent antibody which does not possess the alteration(s). In one embodiment, 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.
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., receptor tyrosine kinase orphan receptor 1, or ROR1). In one exemplary assay, ROR1 is coated on a plate and allowed to bind a first antibody, after which a second, labeled antibody is added. If the presence of the first antibody reduces binding of the second antibody, then the antibodies compete. In another exemplary assay, a first antibody is coated on a plate and allowed to bind the antigen, and then the second antibody is added. 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 50%, at least 60%, at least 70%, at least 80%, or at least 90%.
The term “epitope” means a portion of an antigen capable of specific binding to an antibody. Epitopes frequently consist of 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 is 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 variants of ROR1 with different point-mutations.
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.
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. Polypeptide sequences having such substitutions are known as “conservatively modified variants.” Such conservatively modified variants are in addition to and do not exclude polymorphic variants, interspecies homologs, and alleles. By way of example, the groups of amino acids provided in Tables 2-4 are, in some embodiments, considered conservative substitutions for one another.
Additional conservative substitutions may be found, for example, in Creighton, Proteins: Structures and Molecular Properties 2nd ed. (1993) W. H. Freeman & Co., New York, NY. An antibody generated by making one or more conservative substitutions of amino acid residues in a parent antibody is referred to as a “conservatively modified variant.”
The term “payload” refers to a molecular moiety that can be conjugated to an antibody. In particular embodiments, payloads are selected from the group consisting of therapeutic moieties and labelling moieties.
“Triple negative breast cancer” (TNBC) refers to a breast cancer characterized as estrogen receptor-negative, progesterone receptor-negative and human epidermal growth factor receptor-2-negative (HER2-negative). The TNBC can be BRCA1/2 wildtype or BRCA1/2 mutated. The determination of negative status of the estrogen, progesterone, and Her2/neu expression is readily determined by one of skill in the art, e.g., in accordance with the current accepted guidelines. For example, guidelines set forth by the American Society of Clinical Oncology (ASCO) and the College of American Pathologists (CAP) are widely accepted. The ASCO/CAP recommends testing by immunohistochemistry (IHC) or in situ hybridization (ISH) techniques. Further, a cancer is Her2 negative if a single test (or all tests) performed on a tumor specimen show: (a) IHC negative, IHC 1+ or IHC 0, or (b) ISH negative using single-probe ISH or dual-probe ISH. One of skill in the art would recognize that the triple negative cancer described herein does not include any cancer having an apparent histopathologic discordance as observed by the pathologist. Wolff, A C et al. J Clin Oncol. 2013 Nov. 1:31(31):3997-4013. Cancer is ER-negative or PR-negative if <1% of tumor cell nuclei are immunoreactive in the presence of evidence that the sample can express ER or PR (positive intrinsic controls are seen).
“PARP inhibitor-resistant” refers to the reduced effectiveness of PARP inhibitors in treating, curing, or improving triple negative breast cancer in a subject. In certain embodiments, the PARP inhibitor-resistance develops with prolonged exposure to one or more PARP inhibitors.
As used herein, the term “therapeutically effective amount” or “effective amount” refers to an amount of an antibody, antibody conjugate, or composition that when administered to a subject is effective to treat a disease or disorder. In some embodiments, a therapeutically effective amount or effective amount refers to an amount of an antibody, antibody conjugate, or composition that when administered to a subject is effective to prevent or ameliorate a disease or the progression of the disease, or result in amelioration of symptoms. A “therapeutically effective amount” can vary depending on, inter alia, the compound, the disease or disorder and its severity, and the age, weight, etc., of the subject to be treated.
As used herein, the term “inhibits growth” (e.g., referring to cells, such as tumor cells) is intended to include any measurable decrease in cell growth (e.g., tumor cell growth) when contacted with a ROR1 antibody or antibody conjugate described herein, as compared to the growth of the same cells not in contact with a ROR1 antibody. In some embodiments, growth may be inhibited by at least about 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 99%, or 100%. The decrease in cell growth can occur by a variety of mechanisms, including but not limited to antibody internalization, apoptosis, necrosis, and/or effector function-mediated activity.
In some chemical structures illustrated herein, certain substituents, chemical groups, and atoms are depicted with a curvy/wavy line (e.g., ) that intersects a bond or bonds to indicate the atom through which the substituents, chemical groups, and atoms are bonded. For example, in some structures, such as but not limited to
this curvy/wavy line indicates the atoms in the backbone of a conjugate or linker-payload structure to which the illustrated chemical entity is bonded. In some structures, such as but not limited to
this curvy/wavy line indicates the atoms in the antibody or antibody fragment as well as the atoms in the backbone of a conjugate or linker-payload structure to which the illustrated chemical entity is bonded.
Spiro compounds depicted with overlapping rings indicate that the rings can bond at any vertex. For instance, in the spiro group
the two rings can bond at any of the three available vertex atoms in either ring.
When referring to the compounds provided herein, the following terms have the following meanings unless indicated otherwise. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of ordinary skill in the art. In the event that there is a plurality of definitions for a term herein, those in this section prevail unless stated otherwise.

After a linker forms a bond to a macromolecular moiety, or a compound or drug moiety, or both, the remaining structure (i.e. the residue of the linker (“linker residue”) after one or more covalent bonds are formed) may still be referred to as a “linker” herein. The term “linker precursor” refers to a linker having one or more reactive groups capable of forming a covalent bond with a macromolecule, or compound or drug moiety, or both. A person of ordinary skill in the art, given the context of how the term linker is used, would understand whether “linker” means linker precursor with one reactive group, a linker precursor with more than one reactive groups, a linker residue which is covalently bonded to the macromolecule, a linker residue which is covalently bonded to a compound or drug moiety, and/or a linker residue which is covalently bonded to the macromolecule and is covalently bonded to a compound or drug moiety. In some embodiments, the linker is a cleavable linker. For example, a cleavable linker can be one that is released by a bio-labile or enzymatic function, which may or may not be engineered. In some embodiments, the linker is a non-cleavable linker. For example, a non-cleavable linker can be one that is released upon degradation of the macromolecular moiety.

WO 97/22596, WO 97/30035, WO 97/32856, and WO 98/13354).
In certain embodiments, the payload is selected from the group consisting of maytansine, hemiasterlin, amanitin, exatecan, deruxtecan (DXd), anthracycline, PNU-159682, pyrrolobenzodiazepine (PBD), MMAF, and MMAE.

In certain embodiments, the payload is pyrrolobenzodiazepine. In certain embodiments, the payload is MMAF. In certain embodiments, the payload is MMAE.
In certain embodiments, the payload is an antibody or an antibody fragment. In certain embodiments, the payload antibody or fragment can be encoded by any of the immunoglobulin genes recognized by those of skill in the art. The immunoglobulin genes include, but are not limited to, the κ, λ, α, γ (IgG1, IgG2, IgG3, and IgG4), δ, ε and μ constant region genes, as well as the immunoglobulin variable region genes. The term includes full-length antibody and antibody fragments recognized by those of skill in the art, and variants thereof. Exemplary fragments include but are not limited to Fv, Fc, Fab, and (Fab)2, single chain Fv (scFv), diabodies, triabodies, tetrabodies, bifunctional hybrid polypeptides, CDR1, CDR2, CDR3, combinations of CDR's, variable regions, framework regions, constant regions, and the like.
In certain embodiments, the payload is one or more water-soluble polymers. A wide variety of macromolecular polymers and other molecules can be linked to the polypeptides described herein to modulate biological properties of the polypeptide, and/or provide new biological properties to the polypeptide. These macromolecular polymers can be linked to the polypeptide via a naturally encoded amino acid, via a non-naturally encoded amino acid, or any functional substituent of a natural or modified amino acid, or any substituent or functional group added to a natural or modified amino acid. The molecular weight of the polymer may be of a wide range, including but not limited to, between about 100 Da and about 100,000 Da or more.
The polymer selected may be water soluble so that a protein to which it is attached does not precipitate in an aqueous environment, such as a physiological environment. The polymer may be branched or unbranched. Preferably, for therapeutic use of the end-product preparation, the polymer will be pharmaceutically acceptable.
In certain embodiments, the proportion of polyethylene glycol molecules to polypeptide molecules will vary, as will their concentrations in the reaction mixture. In general, the optimum ratio (in terms of efficiency of reaction in that there is minimal excess unreacted protein or polymer) may be determined by the molecular weight of the polyethylene glycol selected and on the number of available reactive groups available. As relates to molecular weight, typically the higher the molecular weight of the polymer, the fewer number of polymer molecules which may be attached to the protein. Similarly, branching of the polymer should be taken into account when optimizing these parameters. Generally, the higher the molecular weight (or the more branches) the higher the polymer:protein ratio.
The water-soluble polymer may be any structural form including but not limited to linear, forked or branched. Typically, the water soluble polymer is a poly(alkylene glycol), such as poly(ethylene glycol) (PEG), but other water soluble polymers can also be employed. By way of example, PEG is used to describe certain embodiments.
PEG is a well-known, water-soluble polymer that is commercially available or can be prepared by ring-opening polymerization of ethylene glycol according to methods well known in the art (Sandler and Karo, Polymer Synthesis, Academic Press, New York, Vol. 3, pages 138-161). The term “PEG” is used broadly to encompass any polyethylene glycol molecule, without regard to size or to modification at an end of the PEG, and can be represented as linked to a polypeptide by the formula: XO—(CH2CH2O)n—CH2CH2—Y where n is 2 to 10,000, X is H or a terminal modification, including but not limited to, a C1-4 alkyl, and Y is the attachment point to the polypeptide.
In some cases, a PEG terminates on one end with hydroxy or methoxy, i.e., X is H or CH3 (“methoxy PEG”). Alternatively, the PEG can terminate with a reactive group, thereby forming a bifunctional polymer. Typical reactive groups can include those reactive groups that are commonly used to react with the functional groups found in the 20 common amino acids (including but not limited to, maleimide groups, activated carbonates (including but not limited to, p-nitrophenyl ester), activated esters (including but not limited to, N-hydroxysuccinimide, p-nitrophenyl ester, and aldehydes) as well as functional groups that are inert to the 20 common amino acids but that react specifically with complementary functional groups present in non-naturally encoded amino acids (including but not limited to, azide groups, alkyne groups). It is noted that the other end of the PEG, which is shown in the above formula by Y, will attach either directly or indirectly to a polypeptide via a naturally-occurring or non-naturally encoded amino acid. For instance, Y may be an amide, carbamate, or urea linkage to an amine group (including but not limited to, the epsilon amine of lysine or the N-terminus) of the polypeptide. Alternatively, Y may be a maleimide linkage to a thiol group (including but not limited to, the thiol group of cysteine). Alternatively, Y may be a linkage to a residue not commonly accessible via the 20 common amino acids. For example, an azide group on the PEG can be reacted with an alkyne group on the polypeptide to form a Huisgen [3+2] cycloaddition product. Alternatively, an alkyne group on the PEG can be reacted with an azide group present in a non-naturally encoded amino acid, such as the modified amino acids described herein, to form a similar product. In some embodiments, a strong nucleophile (including but not limited to, hydrazine, hydrazide, hydroxylamine, semicarbazide) can be reacted with an aldehyde or ketone group present in a non-naturally encoded amino acid to form a hydrazone, oxime or semicarbazone, as applicable, which in some cases can be further reduced by treatment with an appropriate reducing agent. Alternatively, the strong nucleophile can be incorporated into the polypeptide via a non-naturally encoded amino acid and used to react preferentially with a ketone or aldehyde group present in the water-soluble polymer.
Any molecular mass for a PEG can be used as practically desired, including but not limited to, from about 100 Daltons (Da) to 100,000 Da or more as desired (including but not limited to, sometimes 0.1-50 kDa or 10-40 kDa). Branched chain PEGs, including but not limited to, PEG molecules with each chain having a MW ranging from 1-100 kDa (including but not limited to, 1-50 kDa or 5-20 kDa) can also be used. A wide range of PEG molecules are described in, including but not limited to, the Shearwater Polymers, Inc. catalog, and the Nektar Therapeutics catalog, incorporated herein by reference.
Generally, at least one terminus of the PEG molecule is available for reaction with the antibody. For example, PEG derivatives bearing alkyne and azide moieties for reaction with amino acid side chains can be used to attach PEG to non-naturally encoded amino acids as described herein. If the non-naturally encoded amino acid comprises an azide, then the PEG will typically contain either an alkyne moiety to effect formation of the [3+2] cycloaddition product or an activated PEG species (i.e., ester, carbonate) containing a phosphine group to effect formation of the amide linkage. Alternatively, if the non-naturally encoded amino acid comprises an alkyne, then the PEG will typically contain an azide moiety to effect formation of the [3+2] Huisgen cycloaddition product. If the non-naturally encoded amino acid comprises a carbonyl group, the PEG will typically comprise a potent nucleophile (including but not limited to, a hydrazide, hydrazine, hydroxylamine, or semicarbazide functionality) in order to effect formation of corresponding hydrazone, oxime, and semicarbazone linkages, respectively. In other alternatives, a reverse of the orientation of the reactive groups described herein can be used, i.e., an azide moiety in the non-naturally encoded amino acid can be reacted with a PEG derivative containing an alkyne.
In some embodiments, the polypeptide variant with a PEG derivative contains a chemical functionality that is reactive with the chemical functionality present on the side chain of the non-naturally encoded amino acid.
In certain embodiments, the payload is an azide- or acetylene-containing polymer comprising a water-soluble polymer backbone having an average molecular weight from about 800 Da to about 100,000 Da. The polymer backbone of the water-soluble polymer can be poly(ethylene glycol). However, it should be understood that a wide variety of water soluble polymers including but not limited to poly(ethylene)glycol and other related polymers, including poly(dextran) and poly(propylene glycol), are also suitable for use and that the use of the term PEG or poly(ethylene glycol) is intended to encompass and include all such molecules. The term PEG includes, but is not limited to, poly(ethylene glycol) in any of its forms, including bifunctional PEG, multiarmed PEG, derivatized PEG, forked PEG, branched PEG, pendent PEG (i.e. PEG or related polymers having one or more functional groups pendent to the polymer backbone), or PEG with degradable linkages therein.
The polymer backbone can be linear or branched. Branched polymer backbones are generally known in the art. Typically, a branched polymer has a central branch core moiety and a plurality of linear polymer chains linked to the central branch core. PEG is commonly used in branched forms that can be prepared by addition of ethylene oxide to various polyols, such as glycerol, glycerol oligomers, pentaerythritol and sorbitol. The central branch moiety can also be derived from several amino acids, such as lysine. The branched poly(ethylene glycol) can be represented in general form as R(-PEG-OH)m in which R is derived from a core moiety, such as glycerol, glycerol oligomers, or pentaerythritol, and m represents the number of arms. Multi-armed PEG molecules, such as those described in U.S. Pat. Nos. 5,932,462 5,643,575; 5,229,490; 4,289,872; U.S. Pat. Appl. 2003/0143596; WO 96/21469; and WO 93/21259, each of which is incorporated by reference herein in its entirety, can also be used as the polymer backbone.
Branched PEG can also be in the form of a forked PEG represented by PEG(-YCHZ2)n, where Y is a linking group and Z is an activated terminal group linked to CH by a chain of atoms of defined length.
Yet another branched form, the pendant PEG, has reactive groups, such as carboxyl, along the PEG backbone rather than at the end of PEG chains.
In addition to these forms of PEG, the polymer can also be prepared with weak or degradable linkages in the backbone. For example, PEG can be prepared with ester linkages in the polymer backbone that are subject to hydrolysis. As shown herein, this hydrolysis results in cleavage of the polymer into fragments of lower molecular weight: -PEG-CO2-PEG-+H2O→PEG-CO2H+HO-PEG- It is understood by those skilled in the art that the term poly(ethylene glycol) or PEG represents or includes all the forms known in the art including but not limited to those disclosed herein.
Many other polymers are also suitable for use. In some embodiments, polymer backbones that are water-soluble, with from 2 to about 300 termini, are particularly suitable. Examples of suitable polymers include, but are not limited to, other poly(alkylene glycols), such as poly(propylene glycol) (“PPG”), copolymers thereof (including but not limited to copolymers of ethylene glycol and propylene glycol), terpolymers thereof, mixtures thereof, and the like. Although the molecular weight of each chain of the polymer backbone can vary, it is typically in the range of from about 800 Da to about 100,000 Da, often from about 6,000 Da to about 80,000 Da.
Those of ordinary skill in the art will recognize that the foregoing list for substantially water-soluble backbones is by no means exhaustive and is merely illustrative, and that all polymeric materials having the qualities described herein are contemplated as being suitable for use.
In some embodiments the polymer derivatives are “multi-functional”, meaning that the polymer backbone has at least two termini, and possibly as many as about 300 termini, functionalized or activated with a functional group. Multifunctional polymer derivatives include, but are not limited to, linear polymers having two termini, each terminus being bonded to a functional group which may be the same or different.
In certain embodiments, the antibodies can be linked to the payloads with one or more linkers capable of reacting with an antibody amino acid and with a payload group. The one or more linkers can be any linkers apparent to those of skill in the art.
The term “linker” is used herein to refer to groups or bonds that normally are formed as the result of a chemical reaction and typically are covalent linkages.
Useful linkers include those described herein. In certain embodiments, the linker is any divalent or multivalent linker known to those of skill in the art. Useful divalent linkers include alkylene, substituted alkylene, heteroalkylene, substituted heteroalkylene, arylene, substituted arylene, heteroarlyene, and substituted heteroarylene. In certain embodiments, the linker is C1-10 alkylene or C1-10 heteroalkylene. In some embodiments, the C1-10heteoalkylene is PEG.
In certain embodiments, the linker is hydrolytically stable. Hydrolytically stable linkages means that the linkages are substantially stable in water and do not react with water at useful pH values, including but not limited to, under physiological conditions for an extended period of time, perhaps even indefinitely. In certain embodiments, the linker is hydrolytically unstable. Hydrolytically unstable or degradable linkages mean that the linkages are degradable in water or in aqueous solutions, including for example, blood. Enzymatically unstable or degradable linkages mean that the linkage can be degraded by one or more enzymes.
As understood in the art, PEG and related polymers may include degradable linkages in the polymer backbone or in the linker group between the polymer backbone and one or more of the terminal functional groups of the polymer molecule. For example, ester linkages formed by the reaction of PEG carboxylic acids or activated PEG carboxylic acids with alcohol groups on a biologically active agent generally hydrolyze under physiological conditions to release the agent.
Other hydrolytically degradable linkages include, but are not limited to, carbonate linkages; imine linkages resulted from reaction of an amine and an aldehyde; phosphate ester linkages formed by reacting an alcohol with a phosphate group; hydrazone linkages which are reaction product of a hydrazide and an aldehyde; acetal linkages that are the reaction product of an aldehyde and an alcohol; orthoester linkages that are the reaction product of a formate and an alcohol; peptide linkages formed by an amine group, including but not limited to, at an end of a polymer such as PEG, and a carboxyl group of a peptide; and oligonucleotide linkages formed by a phosphoramidite group, including but not limited to, at the end of a polymer, and a 5′ hydroxyl group of an oligonucleotide.
A number of different cleavable linkers are known to those of skill in the art. See U.S. Pat. Nos. 4,618,492; 4,542,225, and 4,625,014. The mechanisms for release of an agent from these linker groups include, for example, irradiation of a photolabile bond and acid-catalyzed hydrolysis. U.S. Pat. No. 4,671,958, for example, includes a description of immunoconjugates comprising linkers which are cleaved at the target site in vivo by the proteolytic enzymes of the patient's complement system. The length of the linker may be predetermined or selected depending upon a desired spatial relationship between the polypeptide and the molecule linked to it. In view of the large number of methods that have been reported for attaching a variety of radiodiagnostic compounds, radiotherapeutic compounds, drugs, toxins, and other agents to polypeptides one skilled in the art will be able to determine a suitable method for attaching a given agent to a polypeptide.
The linker may have a wide range of molecular weight or molecular length. Larger or smaller molecular weight linkers may be used to provide a desired spatial relationship or conformation between the polypeptide and the linked entity. Linkers having longer or shorter molecular length may also be used to provide a desired space or flexibility between the polypeptide and the linked entity. Similarly, a linker having a particular shape or conformation may be utilized to impart a particular shape or conformation to the polypeptide or the linked entity, either before or after the polypeptide reaches its target. The functional groups present on each end of the linker may be selected to modulate the release of a polypeptide or a payload under desired conditions. This optimization of the spatial relationship between the polypeptide and the linked entity may provide new, modulated, or desired properties to the molecule.
In some embodiments, provided herein are water-soluble bifunctional linkers that have a dumbbell structure that includes: a) an azide, an alkyne, a hydrazine, a hydrazide, a hydroxylamine, or a carbonyl-containing moiety on at least a first end of a polymer backbone; and b) at least a second functional group on a second end of the polymer backbone. The second functional group can be the same or different as the first functional group. The second functional group, in some embodiments, is not reactive with the first functional group. In some embodiments, water-soluble compounds that comprise at least one arm of a branched molecular structure are provided. For example, the branched molecular structure can be a dendritic structure.
In some embodiments, the linker is derived from a linker precursor selected from the group consisting of: N-succinimidyl-3-(2-pyridyldithio)propionate (SPDP), N-succinimidyl 4-(2-pyridyldithio)pentanoate (SPP), N-succinimidyl 4-(2-pyridyldithio)butanoate (SPDB), N-succinimidyl-4-(2-pyridyldithio)-2-sulfo-butanoate (sulfo-SPDB), N-succinimidyl iodoacetate (SIA), N-succinimidyl(4-iodoacetyl)aminobenzoate (STAB), maleimide PEG NHS, N-succinimidyl 4-(maleimidomethyl)cyclohexanecarboxylate (SMCC), N-sulfosuccinimidyl 4-(maleimidomethyl)cyclohexanecarboxylate (sulfo-SMCC) or 2,5-dioxopyrrolidin-1-yl 17-(2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)-5,8,11,14-tetraoxo-4,7,10,13-tetraazaheptadecan-1-oate (CX1-1). In a specific embodiment, the linker is derived from the linker precursor N-succinimidyl 4-(maleimidomethyl)cyclohexanecarboxylate (SMCC).
In some embodiments, the linker is derived from a linker precursor selected from the group consisting of dipeptides, tripeptides, tetrapeptides, and pentapeptides. In such embodiments, the linker can be cleaved by a protease. Exemplary dipeptides include, but are not limited to, valine-citrulline (vc or val-cit), alanine-phenylalanine (af or ala-phe); phenylalanine-lysine (fk or phe-lys); phenylalanine-homolysine (phe-homolys); and N-methyl-valine-citrulline (Me-val-cit). Exemplary tripeptides include, but are not limited to, glycine-valine-citrulline (gly-val-cit), glycine-glycine-glycine (gly-gly-gly), and glycine-methoxyethoxyethyl)serine-valine (gly-val-citalanine OMESerValAla).
In some embodiments, a linker comprises a self-immolative spacer. In certain embodiments, the self-immolative spacer comprises p-aminobenzyl. In some embodiments, a p-aminobenzyl alcohol is attached to an amino acid unit via an amide bond, and a carbamate, methylcarbamate, or carbonate is made between the benzyl alcohol and the payload (Hamann et al. (2005) Expert Opin. Ther. Patents (2005) 15:1087-1103). In some embodiments, the linker comprises p-aminobenzyloxycarbonyl (PAB). Other examples of self-immolative spacers include, but are not limited to, aromatic compounds that are electronically similar to the PAB group, such as 2-aminoimidazol-5-methanol derivatives (U.S. Pat. No. 7,375,078; Hay et al. (1999) Bioorg. Med. Chem. Lett. 9:2237) and ortho- or para-aminobenzylacetals. In some embodiments, spacers can be used that undergo cyclization upon amide bond hydrolysis, such as substituted and unsubstituted 4-aminobutyric acid amides (Rodrigues et al. (1995) Chemistry Biology 2:223), appropriately substituted bicyclo[2.2.1] and bicyclo[2.2.2] ring systems (Storm et al. (1972) J. Amer. Chem. Soc. 94:5815) and 2-aminophenylpropionic acid amides (Amsberry, et al. (1990) J. Org. Chem. Linkage of a drug to the α-carbon of a glycine residue is another example of a self-immolative spacer that may be useful in conjugates (Kingsbury et al. (1984) J. Med. Chem. 27:1447).
In certain embodiments, linker precursors can be combined to form larger linkers. For instance, in certain embodiments, linkers comprise the dipeptide valine-citrulline and p-aminobenzyloxycarbonyl. These are also referenced as citValCit-PAB linkers.
In certain embodiments, the payloads can be linked to the linkers, referred to herein as a linker-payload, with one or more linker groups capable of reacting with an antibody amino acid group.

In certain embodiments, an antibody 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.”
“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.
“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.
Addition or deletion of N-linked glycosylation sites to the antibody 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.
In certain embodiments, amino acid modifications may be introduced into the Fc region of an antibody provided herein to generate an Fc region variant. In certain embodiments, the Fc region variant possesses some, but not all, effector functions. Such antibodies may be useful, for example, in applications in which the half-life of the antibody in vivo is important, yet certain effector functions are unnecessary or deleterious. Examples of effector functions include complement-dependent cytotoxicity (CDC) and antibody-directed complement-mediated cytotoxicity (ADCC). Numerous substitutions or substitutions or deletions with altered effector function are known in the art.
In some embodiments, the Fc comprises one or more modifications in at least one of the CH3 sequences. In some embodiments, the Fc comprises one or more modifications in at least one of the CH2 sequences. For example, the Fc can include one or modifications selected from the group consisting of: V262E, V262D, V262K, V262R, V262S, V264S, V303R, and V305R. In some embodiments, an Fc is a single polypeptide. In some embodiments, an Fc is multiple peptides, e.g., two polypeptides. Exemplary modifications in the Fc region are described, for example, in International Patent Application No. PCT/US2017/037545, filed Jun. 14, 2017.
An alteration in in CDC and/or ADCC activity can be confirmed using in vitro and/or in vivo assays. For example, Fc receptor (FcR) binding assays can be conducted to measure FcγR binding. The primary cells for mediating ADCC, NK cells, express FcγRIII only, whereas monocytes express FcγRI, FcγRII and FcγRIII FcR expression on hematopoietic cells is summarized in Ravetch and Kinet, Ann. Rev. Immunol., 1991, 9:457-492, incorporated by reference in its entirety.

U.S.A., 1986, 83:7059-7063; Hellstrom et al., Proc. Natl. Acad. Sci. U.S.A., 1985, 82:1499-1502; and Bruggemann et al., J. Exp. Med., 1987, 166:1351-1361; each of which is incorporated by reference in its entirety. Useful effector cells for such assays include peripheral blood mononuclear cells (PBMC) and Natural Killer (NK) cells. Alternatively, or additionally, ADCC activity of the molecule of interest may be assessed in vivo, using an animal model such as that disclosed in Clynes et al. Proc. Natl. Acad. Sci. U.S.A., 1998, 95:652-656, incorporated by reference in its entirety.
C1q binding assays may also be carried out to confirm that the antibody is unable to bind C1q and hence lacks CDC activity. Examples of C1q binding assays include those described in WO 2006/029879 and WO 2005/100402, each of which is incorporated by reference in its entirety.
Complement activation assays include those described, for example, in Gazzano-Santoro et al., J. Immunol. Methods, 1996, 202:163-171; Cragg et al., Blood, 2003, 101:1045-1052; and Cragg and Glennie, Blood, 2004, 103:2738-2743; each of which is incorporated by reference in its entirety.
FcRn binding and in vivo clearance (half-life determination) can also be measured, for example, using the methods described in Petkova et al., Intl. Immunol., 2006, 18:1759-1769, incorporated by reference in its entirety.
When the antibody conjugate comprises a modified amino acid, the modified amino acid can be any modified amino acid deemed suitable by the practitioner. In particular embodiments, the modified amino acid comprises a reactive group useful for forming a covalent bond to a linker precursor or to a payload precursor. In certain embodiments, the modified amino acid is a non-natural amino acid. In certain embodiments, the reactive group is selected from the group consisting of amino, carboxy, acetyl, hydrazino, hydrazido, semicarbazido, sulfanyl, azido and alkynyl. Modified amino acids are also described in, for example, WO 2013/185115 and WO 2015/006555, each of which is incorporated herein by reference in its entirety.
In certain embodiments, the amino acid residue is according to any of the following formulas:
Those of skill in the art will recognize that antibodies are generally comprised of L-amino acids However, with non-natural amino acids, the present methods and compositions provide the practitioner with the ability to use L-, D- or racemic non-natural amino acids at the site-specific positions. In certain embodiments, the non-natural amino acids described herein include D-versions of the natural amino acids and racemic versions of the natural amino acids.
In the above formulas, the wavy lines indicate bonds that connect to the remainder of the polypeptide chains of the antibodies. These non-natural amino acids can be incorporated into polypeptide chains just as natural amino acids are incorporated into the same polypeptide chains. In certain embodiments, the non-natural amino acids are incorporated into the polypeptide chain via amide bonds as indicated in the formulas.
In the above formulas, R designates any functional group without limitation, so long as the amino acid residue is not identical to a natural amino acid residue. In certain embodiments, R can be a hydrophobic group, a hydrophilic group, a polar group, an acidic group, a basic group, a chelating group, a reactive group, a therapeutic moiety or a labeling moiety. In certain embodiments, R is selected from the group consisting of R1aNR2aR3a, R1aC(O)R2a, R1aC(═O)OR2a, R1aN3, R1aC(≡CH). In these embodiments, R1a is selected from the group consisting of a bond, alkylene, heteroalkylene, arylene, heteroarylene. R2a and R3a are each independently selected from the group consisting of hydrogen, alkyl and heteroalkyl.
In some embodiments, the non-naturally encoded amino acids include side chain functional groups that react efficiently and selectively with functional groups not found in the 20 common amino acids (including but not limited to, azido, ketone, aldehyde and aminooxy groups) to form stable conjugates. For example, antigen-binding polypeptide that includes a non-naturally encoded amino acid containing an azido functional group can be reacted with a polymer (including but not limited to, poly(ethylene glycol) or, alternatively, a second polypeptide containing an alkyne moiety to form a stable conjugate resulting for the selective reaction of the azide and the alkyne functional groups to form a Huisgen [3+2] cycloaddition product.
Exemplary non-naturally encoded amino acids that may be suitable for use in the present invention and that are useful for reactions with water soluble polymers include, but are not limited to, those with carbonyl, aminooxy, hydrazine, hydrazide, semicarbazide, azide and alkyne reactive groups. In some embodiments, non-naturally encoded amino acids comprise a saccharide moiety. Examples of such amino acids include N-acetyl-L-glucosaminyl-L-serine, N-acetyl-L-galactosaminyl-L-serine, N-acetyl-L-glucosaminyl-L-threonine, N-acetyl-L-glucosaminyl-L-asparagine and O-mannosaminyl-L-serine. Examples of such amino acids also include examples where the naturally-occurring N- or O-linkage between the amino acid and the saccharide is replaced by a covalent linkage not commonly found in nature—including but not limited to, an alkene, an oxime, a thioether, an amide and the like. Examples of such amino acids also include saccharides that are not commonly found in naturally-occurring proteins such as 2-deoxy-glucose, 2-deoxygalactose and the like.
Many of the non-naturally encoded amino acids provided herein are commercially available, e.g., from Sigma-Aldrich (St. Louis, Mo., USA), Novabiochem (a division of EMD Biosciences, Darmstadt, Germany), or Peptech (Burlington, Mass., USA).

wherein Z typically comprises OH, NH2, SH, NH—R′, or S—R′; Xb and Yb, which can be the same or different, typically comprise S or O, and R and R′, which are optionally the same or different, are typically selected from the same list of constituents for the R group described herein for the unnatural amino acids having Formula I-I as well as hydrogen. For example, unnatural amino acids of the invention optionally comprise substitutions in the amino or carboxyl group as illustrated by Formulas II-I and III-I. Unnatural amino acids of this type include, but are not limited to, α-hydroxy acids, α-thioacids, α-aminothiocarboxylates, including but not limited to, with side chains corresponding to the common twenty natural amino acids or unnatural side chains. In addition, substitutions at the α-carbon optionally include, but are not limited to, L, D, or α-α-disubstituted amino acids such as D-glutamate, D-alanine, D-methyl-O-tyrosine, aminobutyric acid, and the like. Other structural alternatives include cyclic amino acids, such as proline analogues as well as 3, 4, 6, 7, 8, and 9 membered ring proline analogues, P and y amino acids such as substituted β-alanine and γ-amino butyric acid.

Amino acids with a carbonyl reactive group allow for a variety of reactions to link molecules (including but not limited to, PEG or other water soluble molecules) via nucleophilic addition or aldol condensation reactions among others.
Exemplary carbonyl-containing amino acids can be represented as follows:
wherein n3 is 0-10; R1b is an alkyl, aryl, substituted alkyl, or substituted aryl; R2b is H, alkyl, aryl, substituted alkyl, and substituted aryl; and R3b is H, an amino acid, a polypeptide, or an amino terminus modification group, and R4b is H, an amino acid, a polypeptide, or a carboxy terminus modification group. In some embodiments, n3 is 1, R1b is phenyl and R2b is a simple alkyl (i.e., methyl, ethyl, or propyl) and the ketone moiety is positioned in the para position relative to the alkyl side chain. In some embodiments, n3 is 1, R1b is phenyl and R2b is a simple alkyl (i.e., methyl, ethyl, or propyl) and the ketone moiety is positioned in the meta position relative to the alkyl side chain.
In some examples, a non-naturally encoded amino acid bearing adjacent hydroxyl and amino groups can be incorporated into the polypeptide as a “masked” aldehyde functionality. For example, 5-hydroxylysine bears a hydroxyl group adjacent to the epsilon amine. Reaction conditions for generating the aldehyde typically involve addition of molar excess of sodium metaperiodate under mild conditions to avoid oxidation at other sites within the polypeptide. The pH of the oxidation reaction is typically about 7.0. A typical reaction involves the addition of about 1.5 molar excess of sodium meta periodate to a buffered solution of the polypeptide, followed by incubation for about 10 minutes in the dark. See, e.g. U.S. Pat. No. 6,423,685, which is incorporated by reference herein.
The carbonyl functionality can be reacted selectively with a hydrazine-, hydrazide-, hydroxylamine-, or semicarbazide-containing reagent under mild conditions in aqueous solution to form the corresponding hydrazone, oxime, or semicarbazone linkages, respectively, that are stable under physiological conditions. See, e.g., Jencks, W. P., J. Am. Chem. Soc. 81, 475-481 (1959); Shao, J. and Tam, J. P., J. Am. Chem. Soc. 117:3893-3899 (1995). Moreover, the unique reactivity of the carbonyl group allows for selective modification in the presence of the other amino acid side chains. See, e.g., Cornish, V. W., et al., J. Am. Chem. Soc. 118:8150-8151 (1996); Geoghegan, K. F. & Stroh, J. G., Bioconjug. Chem. 3:138-146 (1992); Mahal, L. K., et al., Science 276:1125-1128 (1997).
Non-naturally encoded amino acids containing a nucleophilic group, such as a hydrazine, hydrazide or semicarbazide, allow for reaction with a variety of electrophilic groups to form conjugates (including but not limited to, with PEG or other water soluble polymers).
Exemplary hydrazine, hydrazide or semicarbazide-containing amino acids can be represented as follows:
wherein n3 is 0-10; R1c is an alkyl, aryl, substituted alkyl, or substituted aryl or not present; Xc, is N, or S or not present; R2c is H, an amino acid, a polypeptide, or an amino terminus modification group, and R3c is H, an amino acid, a polypeptide, or a carboxy terminus modification group.
In some embodiments, n3 is 4, R1c is not present, and X is N. In some embodiments, n3 is 2, R1c is not present, and X is not present. In some embodiments, n3 is 1, R1c is phenyl, X is O, and the oxygen atom is positioned para to the aliphatic group on the aryl ring.
Hydrazide-, hydrazine-, and semicarbazide-containing amino acids are available from commercial sources. For instance, L-glutamate-γ-hydrazide is available from Sigma Chemical (St. Louis, Mo.). Other amino acids not available commercially can be prepared by one skilled in the art. See, e.g., U.S. Pat. No. 6,281,211, which is incorporated by reference herein.
Polypeptides containing non-naturally encoded amino acids that bear hydrazide, hydrazine or semicarbazide functionalities can be reacted efficiently and selectively with a variety of molecules that contain aldehydes or other functional groups with similar chemical reactivity. See, e.g., Shao, J. and Tam, J., J. Am. Chem. Soc. 117:3893-3899 (1995). The unique reactivity of hydrazide, hydrazine and semicarbazide functional groups makes them significantly more reactive toward aldehydes, ketones and other electrophilic groups as compared to the nucleophilic groups present on the 20 common amino acids (including but not limited to, the hydroxyl group of serine or threonine or the amino groups of lysine and the N-terminus).
Non-naturally encoded amino acids containing an aminooxy (also called a hydroxylamine) group allow for reaction with a variety of electrophilic groups to form conjugates (including but not limited to, with PEG or other water soluble polymers). Like hydrazines, hydrazides and semicarbazides, the enhanced nucleophilicity of the aminooxy group permits it to react efficiently and selectively with a variety of molecules that contain aldehydes or other functional groups with similar chemical reactivity. See, e.g., Shao, J. and Tam, J., J. Am. Chem. Soc. 117:3893-3899 (1995); H. Hang and C. Bertozzi, Acc. Chem. Res. 34: 727-736 (2001). Whereas the result of reaction with a hydrazine group is the corresponding hydrazone, however, an oxime results generally from the reaction of an aminooxy group with a carbonyl-containing group such as a ketone.
Exemplary amino acids containing aminooxy groups can be represented as follows:
wherein n3 is 0-10; R1c is an alkyl, aryl, substituted alkyl, or substituted aryl or not present; Xc is O, N, S or not present; m3 is 0-10; Yc is ═C(O) or not present; R2c is H, an amino acid, a polypeptide, or an amino terminus modification group, and R3c is H, an amino acid, a polypeptide, or a carboxy terminus modification group. In some embodiments, n3 is 1, R1a is phenyl, Xc is O, m is 1, and Yc is present. In some embodiments, n3 is 2, R1c and Xc are not present, m3 is 0, and Yc is not present.
Aminooxy-containing amino acids can be prepared from readily available amino acid precursors (homoserine, serine and threonine). See, e.g., M. Carrasco and R. Brown, J. Org. Chem. 68: 8853-8858 (2003). Certain aminooxy-containing amino acids, such as L-2-amino-4-(aminooxy)butyric acid), have been isolated from natural sources (Rosenthal, G. et al., Life Sci. 60: 1635-1641 (1997). Other aminooxy-containing amino acids can be prepared by one skilled in the art.
The unique reactivity of azide and alkyne functional groups makes them extremely useful for the selective modification of polypeptides and other biological molecules. Organic azides, particularly aliphatic azides, and alkynes are generally stable toward common reactive chemical conditions. In particular, both the azide and the alkyne functional groups are inert toward the side chains (i.e., R groups) of the 20 common amino acids found in naturally-occurring polypeptides. When brought into close proximity, however, the “spring-loaded” nature of the azide and alkyne groups is revealed and they react selectively and efficiently via Huisgen [3+2] cycloaddition reaction to generate the corresponding triazole. See, e.g., Chin J., et al., Science 301:964-7 (2003); Wang, Q., et al., J. Am. Chem. Soc. 125, 3192-3193 (2003); Chin, J. W., et al., J. Am. Chem. Soc. 124:9026-9027 (2002).
Because the Huisgen cycloaddition reaction involves a selective cycloaddition reaction (see, e.g., Padwa, A., in COMPREHENSIVE ORGANIC SYNTHESIS, Vol. 4, (ed. Trost, B. M., 1991), p. 1069-1109; Huisgen, R. in 1,3-DIPOLAR CYCLOADDITION CHEMISTRY, (ed. Padwa, A., 1984), p. 1-176) rather than a nucleophilic substitution, the incorporation of non-naturally encoded amino acids bearing azide and alkyne-containing side chains permits the resultant polypeptides to be modified selectively at the position of the non-naturally encoded amino acid. Cycloaddition reaction involving azide or alkyne-containing antibody can be carried out at room temperature under aqueous conditions by the addition of Cu(II) (including but not limited to, in the form of a catalytic amount of CuSO4) in the presence of a reducing agent for reducing Cu(II) to Cu(I), in situ, in catalytic amount. See, e.g., Wang, Q., et al., J. Am. Chem. Soc. 125, 3192-3193 (2003); Tornoe, C. W., et al., J. Org. Chem. 67:3057-3064 (2002); Rostovtsev, et al., Angew. Chem. Int. Ed. 41:2596-2599 (2002). Exemplary reducing agents include, including but not limited to, ascorbate, metallic copper, quinine, hydroquinone, vitamin K, glutathione, cysteine, Fe2+, Co2+, and an applied electric potential.
In some cases, where a Huisgen [3+2] cycloaddition reaction between an azide and an alkyne is desired, the antigen-binding polypeptide comprises a non-naturally encoded amino acid comprising an alkyne moiety and the water soluble polymer to be attached to the amino acid comprises an azide moiety. Alternatively, the converse reaction (i.e., with the azide moiety on the amino acid and the alkyne moiety present on the water soluble polymer) can also be performed.
The azide functional group can also be reacted selectively with a water soluble polymer containing an aryl ester and appropriately functionalized with an aryl phosphine moiety to generate an amide linkage. The aryl phosphine group reduces the azide in situ and the resulting amine then reacts efficiently with a proximal ester linkage to generate the corresponding amide. See, e.g., E. Saxon and C. Bertozzi, Science 287, 2007-2010 (2000). The azide-containing amino acid can be either an alkyl azide (including but not limited to, 2-amino-6-azido-1-hexanoic acid) or an aryl azide (p-azido-phenylalanine).
Exemplary water soluble polymers containing an aryl ester and a phosphine moiety can be represented as follows:
wherein Xc can be O, N, S or not present, Ph is phenyl, W is a water soluble polymer and R can be H, alkyl, aryl, substituted alkyl and substituted aryl groups. Exemplary R groups include but are not limited to —CH2, —C(CH3)3, —OR′, —NR′R″, —SR′, -halogen, —C(O)R′, —CONR′R″, —S(O)2R′, —S(O)2NR′R″, —CN and —NO2. R′, R″, R′″ and R″″ each independently refer to hydrogen, substituted or unsubstituted heteroalkyl, substituted or unsubstituted aryl, including but not limited to, aryl substituted with 1-3 halogens, substituted or unsubstituted alkyl, alkoxy or thioalkoxy groups, or arylalkyl groups. When a compound of the invention includes more than one R group, for example, each of the R groups is independently selected as are each R′, R″, R′″ and R″″ groups when more than one of these groups is present. When R′ and R″ are attached to the same nitrogen atom, they can be combined with the nitrogen atom to form a 5-, 6-, or 7-membered ring. For example, —NR′R″ is meant to include, but not be limited to, 1-pyrrolidinyl and 4-morpholinyl. From the above discussion of substituents, one of skill in the art will understand that the term “alkyl” is meant to include groups including carbon atoms bound to groups other than hydrogen groups, such as haloalkyl (including but not limited to, —CF3 and —CH2CF3) and acyl (including but not limited to, —C(O)CH3, —C(O)CF3, —C(O)CH2OCH3, and the like).
The azide functional group can also be reacted selectively with a water soluble polymer containing a thioester and appropriately functionalized with an aryl phosphine moiety to generate an amide linkage. The aryl phosphine group reduces the azide in situ and the resulting amine then reacts efficiently with the thioester linkage to generate the corresponding amide. Exemplary water soluble polymers containing a thioester and a phosphine moiety can be represented as follows:
wherein n2 is 1-10; Xc can be O, N, S or not present, Ph is phenyl, and W is a water soluble polymer.
Exemplary alkyne-containing amino acids can be represented as follows:
wherein n3 is 0-10; R1c is an alkyl, aryl, substituted alkyl, or substituted aryl or not present; Xc is O, N, S or not present; m3 is 0-10, R2c is H, an amino acid, a polypeptide, or an amino terminus modification group, and R3c is H, an amino acid, a polypeptide, or a carboxy terminus modification group. In some embodiments, n3 is 1, R1c is phenyl, Xc is not present, m3 is 0 and the acetylene moiety is positioned in the para position relative to the alkyl side chain. In some embodiments, n3 is 1, R1c is phenyl, Xc is O, m3 is 1 and the propargyloxy group is positioned in the para position relative to the alkyl side chain (i.e., 0-propargyl-tyrosine). In some embodiments, n3 is 1, R1c and Xc are not present and m3 is 0 (i.e., proparylglycine).
Alkyne-containing amino acids are commercially available. For example, propargylglycine is commercially available from Peptech (Burlington, Mass.). Alternatively, alkyne-containing amino acids can be prepared according to standard methods. For instance, p-propargyloxyphenylalanine can be synthesized, for example, as described in Deiters, A., et al., J. Am. Chem. Soc. 125: 11782-11783 (2003), and 4-alkynyl-L-phenylalanine can be synthesized as described in Kayser, B., et al., Tetrahedron 53(7): 2475-2484 (1997). Other alkyne-containing amino acids can be prepared by one skilled in the art.
Exemplary azide-containing amino acids can be represented as follows:
wherein n3 is 0-10; R1c is an alkyl, aryl, substituted alkyl, substituted aryl or not present; Xc is O, N, S or not present; m3 is 0-10; R2c is H, an amino acid, a polypeptide, or an amino terminus modification group, and R3c is H, an amino acid, a polypeptide, or a carboxy terminus modification group. In some embodiments, n3 is 1, R1c is phenyl, Xc is not present, m3 is 0 and the azide moiety is positioned para to the alkyl side chain. In some embodiments, n3 is 0-4 and R1c and Xc are not present, and m3=0. In some embodiments, n3 is 1, R1c is phenyl, Xc is O, m3 is 2 and the P-azidoethoxy moiety is positioned in the para position relative to the alkyl side chain.
Azide-containing amino acids are available from commercial sources. For instance, 4-azidophenylalanine can be obtained from Chem-Impex International, Inc. (Wood Dale, Ill.). For those azide-containing amino acids that are not commercially available, the azide group can be prepared relatively readily using standard methods known to those of skill in the art, including but not limited to, via displacement of a suitable leaving group (including but not limited to, halide, mesylate, tosylate) or via opening of a suitably protected lactone. See, e.g., Advanced Organic Chemistry by March (Third Edition, 1985, Wiley and Sons, New York).
The unique reactivity of beta-substituted aminothiol functional groups makes them extremely useful for the selective modification of polypeptides and other biological molecules that contain aldehyde groups via formation of the thiazolidine. See, e.g., J. Shao and J. Tam, J. Am. Chem. Soc. 1995, 117 (14) 3893-3899. In some embodiments, beta-substituted aminothiol amino acids can be incorporated into antibodies and then reacted with water soluble polymers comprising an aldehyde functionality. In some embodiments, a water soluble polymer, drug conjugate or other payload can be coupled to an antibody polypeptide comprising a beta-substituted aminothiol amino acid via formation of the thiazolidine.
Particular examples of useful non-natural amino acids include, but are not limited to, p-acetyl-L-phenylalanine, O-methyl-L-tyrosine, L-3-(2-naphthyl)alanine, 3-methyl-phenylalanine, O-4-allyl-L-tyrosine, 4-propyl-L-tyrosine, tri-O-acetyl-GlcNAc b-serine, L-Dopa, fluorinated phenylalanine, isopropyl-L-phenylalanine, p-azido-methyl-L-phenylalanine, p-azido-L-phenylalanine, p-acyl-L-phenylalanine, p-benzoyl-L-phenylalanine, L-phosphoserine, phosphonoserine, phosphonotyrosine, p-iodo-phenylalanine, p-bromophenylalanine, p-amino-L-phenylalanine, isopropyl-L-phenylalanine, and p-propargyloxy-phenylalanine.

In particular embodiments, the non-natural amino acids are selected from p-acetyl-phenylalanine, p-ethynyl-phenylalanine, p-propargyloxyphenylalanine, p-azido-methyl-phenylalanine, and p-azido-phenylalanine. One particularly useful non-natural amino acid is p-azido phenylalanine. This amino acid residue is known to those of skill in the art to facilitate Huisgen [3+2] cyloaddition reactions (so-called “click” chemistry reactions) with, for example, compounds bearing alkynyl groups. This reaction enables one of skill in the art to readily and rapidly conjugate to the antibody at the site-specific location of the non-natural amino acid.
In certain embodiments, the first reactive group is an alkynyl moiety (including but not limited to, in the unnatural amino acid p-propargyloxyphenylalanine, where the propargyl group is also sometimes referred to as an acetylene moiety) and the second reactive group is an azido moiety, and [3+2] cycloaddition chemistry can be used. In certain embodiments, the first reactive group is the azido moiety (including but not limited to, in the unnatural amino acid p-azido-L-phenylalanine) and the second reactive group is the alkynyl moiety.
In the above formulas, each L represents a divalent linker. The divalent linker can be any divalent linker known to those of skill in the art. Generally, the divalent linker is capable of forming covalent bonds to the functional moiety R and the cognate reactive group (e.g., alpha carbon) of the non-natural amino acid. Useful divalent linkers a bond, alkylene, substituted alkylene, heteroalkylene, substituted heteroalkylene, arylene, substituted arylene, heteroarlyene and substituted heteroarylene. In certain embodiments, L is C1-10 alkylene or C1-10 heteroalkylene.
The non-natural amino acids used in the methods and compositions described herein have at least one of the following four properties: (1) at least one functional group on the sidechain of the non-natural amino acid has at least one characteristics and/or activity and/or reactivity orthogonal to the chemical reactivity of the 20 common, genetically-encoded amino acids (i.e., alanine, arginine, asparagine, aspartic acid, cysteine, glutamine, glutamic acid, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, and valine), or at least orthogonal to the chemical reactivity of the naturally occurring amino acids present in the polypeptide that includes the non-natural amino acid; (2) the introduced non-natural amino acids are substantially chemically inert toward the 20 common, genetically-encoded amino acids; (3) the non-natural amino acid can be stably incorporated into a polypeptide, preferably with the stability commensurate with the naturally-occurring amino acids or under typical physiological conditions, and further preferably such incorporation can occur via an in vivo system; and (4) the non-natural amino acid includes an oxime functional group or a functional group that can be transformed into an oxime group by reacting with a reagent, preferably under conditions that do not destroy the biological properties of the polypeptide that includes the non-natural amino acid (unless of course such a destruction of biological properties is the purpose of the modification/transformation), or where the transformation can occur under aqueous conditions at a pH between about 4 and about 8, or where the reactive site on the non-natural amino acid is an electrophilic site. Any number of non-natural amino acids can be introduced into the polypeptide. Non-natural amino acids may also include protected or masked oximes or protected or masked groups that can be transformed into an oxime group after deprotection of the protected group or unmasking of the masked group. Non-natural amino acids may also include protected or masked carbonyl or dicarbonyl groups, which can be transformed into a carbonyl or dicarbonyl group after deprotection of the protected group or unmasking of the masked group and thereby are available to react with hydroxylamines or oximes to form oxime groups.
In further embodiments, non-natural amino acids that may be used in the methods and compositions described herein include, but are not limited to, amino acids comprising a photoactivatable cross-linker, spin-labeled amino acids, fluorescent amino acids, metal binding amino acids, metal-containing amino acids, radioactive amino acids, amino acids with novel functional groups, amino acids that covalently or non-covalently interact with other molecules, photocaged and/or photoisomerizable amino acids, amino acids comprising biotin or a biotin analogue, glycosylated amino acids such as a sugar substituted serine, other carbohydrate modified amino acids, keto-containing amino acids, aldehyde-containing amino acids, amino acids comprising polyethylene glycol or other polyethers, heavy atom substituted amino acids, chemically cleavable and/or photocleavable amino acids, amino acids with an elongated side chains as compared to natural amino acids, including but not limited to, polyethers or long chain hydrocarbons, including but not limited to, greater than about 5 or greater than about 10 carbons, carbon-linked sugar-containing amino acids, redox-active amino acids, amino thioacid containing amino acids, and amino acids comprising one or more toxic moiety.
In some embodiments, non-natural amino acids comprise a saccharide moiety. Examples of such amino acids include N-acetyl-L-glucosaminyl-L-serine, N-acetyl-L-galactosaminyl-L-serine, N-acetyl-L-glucosaminyl-L-threonine, N-acetyl-L-glucosaminyl-L-asparagine and O-mannosaminyl-L-serine. Examples of such amino acids also include examples where the naturally-occurring N- or O-linkage between the amino acid and the saccharide is replaced by a covalent linkage not commonly found in nature—including but not limited to, an alkene, an oxime, a thioether, an amide and the like. Examples of such amino acids also include saccharides that are not commonly found in naturally-occurring proteins such as 2-deoxy-glucose, 2-deoxygalactose and the like.
The chemical moieties incorporated into antibodies via incorporation of non-natural amino acids offer a variety of advantages and manipulations of polypeptides. For example, the unique reactivity of a carbonyl or dicarbonyl functional group (including a keto- or aldehyde-functional group) allows selective modification of antibodies with any of a number of hydrazine- or hydroxylamine-containing reagents in vivo and in vitro. A heavy atom non-natural amino acid, for example, can be useful for phasing x-ray structure data. The site-specific introduction of heavy atoms using non-natural amino acids also provides selectivity and flexibility in choosing positions for heavy atoms. Photoreactive non-natural amino acids (including but not limited to, amino acids with benzophenone and arylazides (including but not limited to, phenylazide) side chains), for example, allow for efficient in vivo and in vitro photocrosslinking of polypeptides. Examples of photoreactive non-natural amino acids include, but are not limited to, p-azido-phenylalanine and p-benzoyl-phenylalanine. The antibodies with the photoreactive non-natural amino acids may then be crosslinked at will by excitation of the photoreactive group-providing temporal control. In a non-limiting example, the methyl group of a non-natural amino can be substituted with an isotopically labeled, including but not limited to, with a methyl group, as a probe of local structure and dynamics, including but not limited to, with the use of nuclear magnetic resonance and vibrational spectroscopy.
Amino acids with an electrophilic reactive group allow for a variety of reactions to link molecules via various chemical reactions, including, but not limited to, nucleophilic addition reactions. Such electrophilic reactive groups include a carbonyl- or dicarbonyl-group (including a keto- or aldehyde group), a carbonyl-like- or dicarbonyl-like-group (which has reactivity similar to a carbonyl- or dicarbonyl-group and is structurally similar to a carbonyl- or dicarbonyl-group), a masked carbonyl- or masked dicarbonyl-group (which can be readily converted into a carbonyl- or dicarbonyl-group), or a protected carbonyl- or protected dicarbonyl-group (which has reactivity similar to a carbonyl- or dicarbonyl-group upon deprotection). Such amino acids include amino acids having the structure of Formula (I-1):

12.1. Antigen Preparation
The ROR1 protein to be used for isolation of the antibodies may be intact ROR1 or a fragment of ROR1. The intact ROR1 protein, or fragment of ROR1, may be in the form of an isolated protein or protein expressed by a cell. Other forms of ROR1 useful for generating antibodies will be apparent to those skilled in the art.
12.2. Monoclonal Antibodies
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. Pat. No. 4,816,567, incorporated by reference in its entirety). Monoclonal antibodies may also be obtained, for example, using phage or yeast-based libraries. See e.g., U.S. Pat. Nos. 8,258,082 and 8,691,730, each of which is incorporated by reference in its entirety.
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.
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.
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.
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.
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.
12.3. Humanized Antibodies
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. Pat. Nos. 5,585,089, 5,693,762, and 6,180,370; each of which is incorporated by reference in its entirety.
12.4. Human Antibodies
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 al., Year in Immuno., 1993, 7:33; and U.S. Pat. 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. Pat. Nos. 5,567,610 and 5,229,275, each of which is incorporated by reference in its entirety). Human antibodies may also be derived from yeast-based libraries (see e.g., U.S. Pat. No. 8,691,730, incorporated by reference in its entirety).
12.5. Conjugation
The antibody conjugates can be prepared by standard techniques. In certain embodiments, an antibody is contacted with a payload precursor under conditions suitable for forming a bond from the antibody to the payload to form an antibody-payload conjugate. In certain embodiments, an antibody is contacted with a linker precursor under conditions suitable for forming a bond from the antibody to the linker. The resulting antibody-linker is contacted with a payload precursor under conditions suitable for forming a bond from the antibody-linker to the payload to form an antibody-linker-payload conjugate. In certain embodiments, a payload precursor is contacted with a linker precursor under conditions suitable for forming a bond from the payload to the linker. The resulting payload-linker is contacted with an antibody under conditions suitable for forming a bond from the payload-linker to the antibody to form an antibody-linker-payload conjugate. Suitable linkers for preparing the antibody conjugates are disclosed herein, and exemplary conditions for conjugation are described in the Examples below.
In some embodiments, an anti-ROR1 conjugate is prepared by contacting an anti-ROR1 antibody as disclosed herein with a linker precursor having a structure of any of LP1-LP39:
In some embodiments, an anti-ROR1 conjugate is prepared by contacting an anti-ROR1 antibody as disclosed herein with a linker precursor having a structure of any of LP1A-LP39A:
The invention also provides isolated nucleic acids encoding anti-ROR1 antibodies, vectors and host cells comprising the nucleic acids, and recombinant techniques for the production of the antibodies.
The ROR1 antibodies can be prepared according to techniques apparent to the person of skill. In certain embodiments, the ROR1 antibodies are prepared from isolated nucleic acids encoding anti-ROR1 antibodies, vectors, and host cells comprising the nucleic acids, and recombinant techniques for the production of the antibodies.
For recombinant production of the 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. Pat. No. 5,204,244, incorporated by reference in its entirety.
Many different vectors are known in the art. The vector components generally include, but are not limited to, 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. Pat. No. 5,534,615, incorporated by reference in its entirety.
Illustrative examples of suitable host cells are provided below. These host cells are not meant to be limiting.
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 suitable.
In addition to prokaryotes, eukaryotic microbes such as filamentous fungi or yeast are also suitable cloning or expression hosts for anti-ROR1 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 Spodoptera frugiperda (e.g., SF9), 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. occidentalis), and filamentous fungi such as, for example Penicillium, Tolypocladium, and Aspergillus (A. nidulans and A. niger).
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.
The host cells used to produce the anti-ROR1 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 al., Meth. Enz., 1979, 58:44; Barnes et al., Anal. Biochem., 1980, 102:255; and U.S. Pat. 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.
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.
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.
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) 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.
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. The antibodies produced in a cell-free system may be aglycosylated depending on the source of the cells.
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.
The antibody composition prepared from the cells can be purified using, for example, hydroxyapatite 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 are based on human γ1, γ2, or γ4 heavy chains (Lindmark et al., J. Immunol. Meth., 1983, 62:1-13, incorporated by reference in its entirety). Protein G is useful for all mouse isotypes and for human γ3 (Guss et al., EMBO J., 1986, 5:1567-1575, incorporated by reference in its entirety).
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 CH3 domain, the BakerBond ABX® resin is useful for purification.
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.
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).

Generation and Phage Display Selection
Antibody Fab libraries were constructed using an optimized trastuzumab Fab sequence codon optimized in a modified, commercially available p3 phagemid vector (Antibody Design Labs). Briefly, the phagemid vector was modified to express Fab heavy chains as C-terminal p3 fusion proteins, and regulatory regions (start codons, restriction enzyme sites, periplasmic leader sequences) were optimized for Fab display levels. Libraries were constructed using a standard overlap extension PCR protocol with mutagenic primers targeting heavy chain complementary determining regions (CDRs). See Heckman and Pease, Nat. Protoc., 2007, 2:924-932. Libraries were rescued through electroporation in M13-K07 infected SS320 E. coli cells. See Raj an & Sidhu, Methods Enzymol., 2012, 502:3-23; Marks & Bradbury, Methods Mol Biol., 2004, 248:161-76. Following multiple selection rounds, Fab heavy chain pools were transferred into cell-free expression vectors for expression as His6 and FLAG-tagged IgG1.
Ribosome Display Selections
Antibody Fab libraries were constructed using a standard overlap extension PCR protocol with mutagenic primers targeting complementary determining regions (CDRs). See Heckman & Pease, supra. Selections for novel antibodies were performed using standard ribosome display protocols. See Hanes & Plückthun, Proc. Natl. Acad. Sci. U.S.A, 1997, 94:4937-4942. Specifically, Fab-based ribosome display selections were performed according to published protocols. See Stafford et al., 2014, Protein Eng. Des. Sel. 27:97-109; Dreier and Plückthun, 2011, Methods Mol Biol 687:283-306. After multiple rounds of selection, the DNA from RT-PCR output was cloned into an optimized vector for cell-free expression using standard molecular biology techniques. See Yin et al., 2012, mAbs 4. All constructs were HIS- and FLAG-tagged to streamline purification and testing during screening
Primary Screening of Antibody Variants
Libraries of antibody variants generated by selection workflow were transformed into E. coli and grown on agar plates with antibiotic (Kanamycin). Individual colonies were grown in liquid broth (TB+antibiotic Kanamycin), and used as a template for DNA amplification via rolling circle amplification (RCA). The variants were then expressed in a cell-free protein synthesis reaction as described. See Yin et al., mAbs, 2012, 4:217-225. Briefly, cell-free extracts were treated with 50 μM iodoacetamide for 30 min at RT (20° C.) and added to a premix containing cell-free components (see Cai et al., Biotechnol Prg, 2015, 3:823-831), 10% (v/v) RCA DNA template (approximately 10 μg/mL DNA) for HC variants of interest, and 2.5 μg/mL of the trastuzumab LC. 60 μL cell free (CF) reactions were incubated at 30° C. for 12 hr on a shaker at 650 rpm in 96-well plates. 400-1500 colonies were screened, depending on the predicted diversity of different selection campaigns. Following synthesis, each reaction was diluted 1-200, 1-400 secondary antibody, 0.2 million CHO (stained with Oregon Green), and 0.2 million CHO-hROR1.
Secondary Screening of Antibody Variants
The top leads from the initial round of screening were cultured and miniprepped via the Qiaprep 96 Turbo miniprep kit (Qiagen) according to manufacturer's instructions. 5 μg/mL miniprepped HC DNA and 5 μg/mL of the trastuzumab LC was added to 4 mL cell-free reactions and incubated overnight for 12 hr at 30° C., 650 rpm. Expressed variants from clarified cell-free reactions were purified via IMAC purification using a semi-automated high throughput batch purification method. Briefly, purifications were performed in a 96-well plate format where 50 μL/well of IMAC resin (Ni Sepharose High Performance, GE Healthcare) was equilibrated in IMAC binding buffer (50 mM Tris pH 8.0, 300 mM NaCl, 10 mM imidazole), incubated with 1 mL cell-free reaction for 15 minutes followed by two washes in IMAC binding buffer. His-tagged antibody variants were then eluted using 200 μL IMAC elution buffer (50 mM Tris pH 8.0, 300 mM NaCl, 500 mM imidazole) and buffer exchanged into PBS using a 96-well Zeba plate (7 kD MWCO, Thermofisher). Purified antibodies were quantified via high throughput capillary electrophoresis using the Labchip GXII (Perkin Elmer) against a Herceptin standard curve, according to manufacturer's instructions.
Exemplary affinity-matured antibodies are reported in Table 5, below.
A single-chain antibody is made in either the VHVL or VLVH orientation with a linker sequence between the VH and VL domains. Typically scFv linkers are composed of (GGGGS)n repeats where n=3, 4, 5, or 6 for linkers of 15, 20, 25, or 30 residues respectively. For cell-free expression, an N-terminal Met is added, but for mammalian expression a leader peptide is added. On the C-terminal end of the scFv, an Fc sequence can be added to extend in vivo half-life or the scFv can be used directly. An optional linker sequence can be incorporated between the scFv and the Fc. An exemplary scFv-Fc linker sequence is AAGSDQEPKSS (SEQ ID NO: 1035). C-terminal affinity tags can optionally be added to facilitate purification and assay development. An exemplary affinity tag is a C-terminal FlagHis tag GSGDYKDDDDKGSGHHHHHH (SEQ ID NO: 1033). A stop codon is typically inserted at the end of the sequence. An exemplary scFv can include an N-terminal Met residue, a VH domain, a GGGGSGGGGSGGGGS (SEQ ID NO: 1034) linker, a VL domain, an AAGSDQEPKSS (SEQ ID NO: 1035) linker, an Fc domain, a FlagHis tag, and a stop codon.
A protein thermal shift assay was carried out by mixing the protein to be assayed with an environmentally sensitive dye (SYPRO Orange, Life Technologies Cat #S-6650) in a phosphate buffered solution (PBS), and monitoring the fluorescence of the mixture in real time as it underwent controlled thermal denaturation. Protein solutions between 0.2-2 mg/mL were mixed at a 1-1 volumetric ratio with a 1-500 PBS-diluted solution of SYPRO Orange (SYPRO Orange stock dye is 5000× in DMSO). 10 μL aliquots of the protein-dye mixture were dispensed in quadruplicate in a 384-well microplate (Bio-Rad Cat #MSP-3852), and the plate was sealed with an optically clear sealing film (Bio-Rad Cat #MSB-1001) and placed in a 384-well plate real-time thermocycler (Bio-Rad CFX384 Real Time System). The protein-dye mixture was heated from to 95° C., at increments of 0.1° C. per cycle (˜1.5° C. per minute), allowing 3 seconds of equilibration at each temperature before taking a fluorescence measurement. At the end of the experiment, the transition melting temperatures (TM1 and TM2) were determined using the Bio-Rad CFX manager software. TM1 represents the melting temperature of the Fc domain. TM2 represents the melting temperature of the Fab domain.
A high-throughput primary screen was performed to rapidly assess cell binding of antibodies produced in small-scale (60 μL) cell-free reactions. In this screen, four components were combined in equal volumes to a final volume of 100 μL/well in a U-bottom 96-well plate (Greiner Cat #650201) or flat bottom 384 well plate (Greiner Cat #781201). These components are: 1) ROR1-expressing CHO cells (CHO-hROR1) diluted in assay buffer (1×PBS+0.2% BSA, sterile filtered) to achieve a final concentration of 500,000 cells/well, 2) a CHO hROR1-negative cell line stained with CellTrace Oregon Green (Invitrogen Cat #34555) and diluted in assay buffer to achieve a final concentration of 500,000 cells/well, 3) a 1-50 dilution of cell-free reaction producing the antibody of interest diluted in assay buffer, and 4) a secondary anti-human antibody (AlexaFluor 647 AffiniPure F(ab′)2 Donkey anti-human IgG, Fc specific; Jackson ImmunoResearch Cat #709-606-098) diluted 1-100 in assay buffer. Plates were then incubated on ice for one hour. Cells were pelleted by spinning at 1500×g for 5 minutes and resuspended in assay buffer. High-throughput flow cytometry was then performed on resuspended cells on a FACS instrument (BDBiosciences FACSCanto II or BDBiosciences LSR II), and data was analyzed with FlowJo software. Antibody binding was assessed by the proportional level of secondary antibody signal (presumably due to binding to our antibody of interest) on CHO-hROR1 cells compared to the signal on CHO hROR1-negative cells.
Immunoglobulin (Ig, residues 39-151), Frizzled (Fz, residues 165-305), and Kringle (Kr, residues 308-395) domains of ROR1 were constructed with a C-terminal HIS6 tag, expressed in HEK293 cells, and purified (Acro Biosystems). Antibodies were tested for their ability to bind to each of these domains via ELISA. Briefly, 2 μg/mL of Ig, Fz, or Kr were coated to 384-well polystyrene plates for 1 hr at 30° C. in 0.1 M bicarbonate pH8.9 buffer before they were washed and blocked with 2% BSA in PBST (PBS, 0.1% Tween20) for 1 hr. Antibody variants were diluted to 10 μg/mL and further serially diluted 3-fold before 30 μL was applied to the ELISA plates for binding (1 hr at 30° C.). Antibody binding was detected via HRP-conjugated anti-human Fc antibodies (Jackson Immunoresearch) and detection with SuperSignal ELISA Pico Chemiluminescent Substrate (Pierce).
Antibodies were tested for their ability to bind to either ROR1 or ROR2 via ELISA. Briefly, 2 μg/mL of ROR1 or ROR2 (Acro Biosystems) were coated to 384-well polystyrene plates for 1 hr at 30° C. in 0.1 M bicarbonate pH8.9 buffer before they were washed and blocked with 2% BSA in PBST (PBS, 0.1% Tween20) for 1 hr. Antibody variants were diluted to 2.5 μg/mL and further serially diluted 3-fold before 30 μL was applied to the ELISA plates for binding (1 hr at 30° C.). Antibody binding was detected via HRP-conjugated anti-human Fc antibodies (Jackson Immunoresearch) and detection with SuperSignal ELISA Pico Chemiluminescent Substrate (Pierce). Cross-reactivity was reported as a ratio of ROR1-ELISA signal over ROR2-ELISA signal at the highest dilution tested.
Anti-Fc polyclonal antibodies were immobilized onto a CMS chip (GE Life Sciences) using amine coupling chemistry (from Amine Coupling Kit, GE Life Sciences). The immobilization steps were carried out at a flow rate of 25 μL/min in 1×HBS-EP+buffer (GE Life Sciences; 10× Stock diluted before use). The sensor surfaces were activated for 7 min with a mixture of NHS (0.05 M) and EDC (0.2 M). The Anti-Fc antibodies were injected over all 4 flow cells at a concentration of 25 ug/ml in 10 mM sodium acetate, pH 4.5, for 7 min. Ethanolamine (1 M, pH 8.5) was injected for 7 min to block any remaining activated groups. An average of 12,000 response units (RU) of capture antibody was immobilized on each flow cell.
Off-rate and kinetic binding experiments were performed at 25° C. using 1×HBS-EP+buffer. Test and control antibodies were injected over the anti-Fc surface at concentrations of 5-10 μg/mL for 12 seconds at a flow rate of 10 μL/min on flow cells 2, 3 and 4, followed by a buffer wash for 30 seconds at the same flow rate. Kinetic characterization of antibody samples was carried out with a range of antigen concentrations from 1-100 nM and 1 injection of 0 nM antigen (for example, 100, 50, 25, 6.25, 1.56 and 0 nM). After capturing ligand (antibody) on the anti-Fc surface, the analyte (hROR1, Fz or Kr domains, Acro Biosystems, Delaware) was bound for 180 seconds, followed by a 600 second dissociation phase at a flow rate of 50 μL/min. Between each ligand capture and analyte binding cycle, regeneration was carried out using 2 injections of 10 mM Glycine pH 2.0 for 30 seconds at 30 μL/min, followed by a 30 second buffer wash step.
The data was fit with the Biacore T200 Evaluation software, using a 1-1 Langmuir binding model. KD (affinity, nM) was determined as a ratio of the kinetic rate constants calculated from the fits of the association and dissociation phases.
Ntera-2, MDA-MB-231, MCF7, HCT116 and Mino cells were obtained from ATCC. HCT116-hRor1-D02 clone was generated by transfecting HCT116 cells with a plasmid containing human Ror1 cDNA sequence and selected for highest stable expression of hRor1 on the cell surface. MDA-MB-231, MCF7, HCT116 and HCT116-Ror1 cell were maintained in Ham's F-12 high glucose DMEM (50-50) (Cellgro-Mediatech; Manassas, VA) supplemented with 10% heat-inactivated fetal bovine serum (Hyclone; Thermo Scientific; Waltham, MA), 1% Penicillin/Streptomycin (Cellgro-Mediatech; Manassas, VA) and 2 mmol/L-glutamax (Life Technology; Carlsbad, CA). Mino cells were maintained in RPMI-1640 medium (Cellgro-Mediatech; Manassas, VA) supplemented with 20% heat-inactivated fetal bovine serum (Hyclone; Thermo Scientific; Waltham, MA), 1% Penicillin/Streptomycin (Cellgro-Mediatech; Manassas, VA) and 2 mmol/L-glutamax (Life Technology; Carlsbad, CA).
Variants with expression levels>250 nM were tested in a fluorescence-activated cell sorting (FACS) cell-binding assay. For leads from naïve library selection, ROR1 positive MDA-MB-231 cell and ROR1 negative MCF7 cell were used to screen for FACS binders. For leads from affinity maturation library selection, HCT116 cells overexpressing human ROR1 (HCT116-hRor1) and HCT116 parent cells were used to screen for FACS binders.
A mix of ROR1 positive and negative cells was prepared as follows. Ror1 negative cells were washed 2× in PBS then incubated in PBS containing 1 nM CellTrace™ Oregon Green488® (Life Technologies) at 37° C. for 30 minutes. Cells were then washed 2× with RPMI w/10% fetal calf serum (or FCS), washed 2× with FACS buffer (PBS+0.5% BSA), suspended thoroughly in ice-cold FACS buffer at a final concentration of 4×10 6 cells/ml and kept on ice. ROR1 positive cells were washed 2× in PBS and suspended with ice-cold FACS buffer at 4×10 6 cells/ml. ROR1 positive and negative cells were then mixed to obtain a 1-1 cell suspension and seeded at 50 μl per well on 96 well polypropylene plates. 50 μl of 6-12 point dilutions of anti-ROR1 variants starting from concentrations of ˜100-200 nM antibody was dispensed using BioMekFX (Beckman Coulter) into each well. Cells were then incubated on ice for 1 hr, washed with FACS buffer and incubated for 1 hr on ice with 50 μl FACS buffer containing 2.5 μg/ml Alexa647-conjugated Goat Anti-Human IgG dispensed using BioMekFX (Beckman Coulter). Cells were then washed 2× with FACS buffer and fixed for 10 minutes in 200 μl PBS with 2% PFA prior to fluorescence detection. Samples were acquired using a Beckton Dickinson LSRII FACS. Mean Fluorescence Intensity of ROR1 antibody binding was analyzed using FlowJo® software (Tree Star, Inc.).
The internalization of the antibodies was evaluated by drugs conjugated to secondary antibodies in a cell killing assay on target positive cells. For leads from naïve library selection, HCT116 cells overexpressing human ROR1 (HCT116-hRor1-D02) were used to screen for internalizing leads. Cells were washed twice with calcium and magnesium-free Hanks Balanced Salt Solution (HBSS), harvested with HYQ® TASE™ (Hyclone; Thermo Scientific; Waltham, MA) and counted by the Vi-CELL Cell Viability Analyzers (Beckman Coulter, Brea, CA). A total of 625 cells in a volume of 25 μL were seeded in each well of a 384-well half area flat bottom white polystyrene plate. Lead antibodies were formulated at 4× starting concentration in the cell culture medium and filtered through MultiScreenHTs 96-Well Filter Plates (Millipore; Billerica, MA). 12.5 μL of the serial diluted antibody (1-3 serial dilution starting from 10 nM) was added into treatment wells and 12.5 μL of a Fab anti-human Fc conjugated to Duocarmycin SA (Moradec, San Diego) via a cleavable linker was then added into each well at a fixed final concentration of 5 nM. Assay plates were cultured at 37° C. in a CO2 incubator for 120 hrs before assay. For cell viability measurement, 30 μL of Cell Titer-Gb® reagent (Promega Corp. Madison, WI) was added into each well, and plates were processed as per product instructions. Relative luminescence was measured on an ENVISION® plate reader (Perkin-Elmer; Waltham, MA). Relative luminescence readings were converted to % viability using untreated cells as controls. Data was fitted with non-linear regression analysis, using a log(inhibitor) vs. response-variable slope, 4 parameter fit with GraphPad Prism (GraphPad v 5.0, Software; San Diego, CA). Data was expressed as relative cell viability (ATP content) % vs. dose of antibody.
For leads from affinity maturation library selection, target positive Mino cells were used to screen for internalizing leads. Cells were harvested and counted by the Vi-CELL Cell Viability Analyzers (Beckman Coulter, Brea, CA). A total of 12500 cells in a volume of 25 μl were seeded in each well of a 384-well half area flat bottom white polystyrene plate. Lead antibodies were formulated at 4× starting concentration in the cell culture medium and filtered through MultiScreenHTs 96-Well Filter Plates (Millipore; Billerica, MA). 12.5 μL of the serial diluted antibody (1-3 serial dilution starting from 10 nM) was added into treatment wells and 12.5 μL of a nanobody anti-human Fc conjugated to a PBD dimer compound via a val-cit linker, and was then added into each well at a fixed final concentration of 5 nM. Assay plates were cultured at 37° C. in a CO2 incubator for 72 hrs before assay. The cell viability was then measured and data plotted as previous described.
The anti-ROR1 lead antibodies were discovered from a Fab ribosome display library that contained CDR H1, H2, and H3 diversity and utilized a constant LC (trastuzumab LC). In this example, the HCs of the lead antibodies were co-expressed with trastuzumab LC or different LCs derived from anti-CD3 antibodies: hOKT3-LC1, hSP34-LC3, hUCHT1-LC3 to determine if the anti-ROR1 HC leads would retain binding to ROR1 when assembled with anti-CD3 LCs. The HCs of lead antibodies 1944-A07, 1987-C05, and 1943-B03 were co-expressed with either trastuzumab LC (parental antibody control) or the LCs of hSP34-LC3, hUCHT1-LC3, or hOKT3-LC1. The antibodies were then purified and tested for ROR1 binding by ELISA. The ELISA assay was carried out as follows. Briefly, 2 μg/mL of ROR1 was coated to a 384-well polystyrene plate for 1 hr at 30° C. in 0.1 M bicarbonate pH8.9 buffer before it was washed and blocked with 2% BSA in PBST (PBS, 0.1% Tween20) for 1 hr. Antibody variants were diluted to 5 μg/mL and further serially diluted 3-fold before 30 μL was applied to the ELISA plates for binding (1 hr at Antibody binding was detected via HRP-conjugated anti-human Fc antibodies (Jackson Immunoresearch) and detection with SuperSignal ELISA Pico Chemiluminescent Substrate (Pierce).
Both 1944-A07 and 1987-C05 maintained varying degrees of binding to ROR1 when combined with different anti-CD3 LCs. However, most ROR1 binding was lost for 1943-B03 when assembled with LCs other than trastuzumab LC. See
For anti-CD3-LC-containing IgGs that had detectable ROR1-binding in ELISA (1944-A07 and 1987-C05 variants), those antibodies were further tested for binding by surface plasmon resonance (SPR). Binding kinetics were assessed to the ROR1-frizzled domain (hROR1-Fz) or the ROR1-extracellular domain (hROR1) for 1944-A07 and 1987-C05 variants, respectively. Briefly, anti-ROR1 antibodies were captured via anti-human Fc polyclonal antibodies immobilized to a CM5 chip, and ROR1 recombinant proteins were flowed across the surface to assess binding kinetics. hROR1 or hROR1-Fz domain (Acro Biosystems, Delaware) binding was tested at 100, 50, 25, 6.25, 1.5625 nM. The data was fit with the Biacore™ T200 Evaluation software, using a 1-1 Langmuir binding model. KD (affinity, nM) was determined as a ratio of the kinetic rate constants calculated from the fits of the association and dissociation phases. See Tables 6 and 7.
Binding kinetics fell in a similar range (KD˜5-10 nM) for the 1944-A07 variants, with the exception of hUCHT1-LC-containing antibodies for which binding was not detected. Binding kinetics of 1987-C05 variants also fell into the 1-2 nM KD range, with no detectable binding when combined with hSP34-LC3 or hOKT3-LC1. The kinetic results differed slightly from the ELISA-based results which may be attributed to differences in assay format, whereas SPR detects monovalent affinities and ELISA measures equilibrium binding of a bivalent antibody. See

Non-natural para-azidomethylphenylalanine (pAMF) residues were incorporated in monoclonal antibodies (mAbs) in place of specific residues using XpressCF+® cell-free expression platform (Yin et al., 2017, Sci Rep 7(1):3026). Sites were chosen for pAMF incorporation to enable the conjugation of cytotoxin moieties via copper-catalyzed azide-alkyne cycloaddition (CuAAC) or a copper-free conjugation method, e.g., strain-promoted azide-alkyne cycloaddition (SPAAC) through dibenzocyclooctyne (DBCO or MO). mAbs were purified through affinity chromatography column followed by ion exchange chromatography columns.
Dibenzocylcooctyne (DBCO) compound was dissolved in dimethylsulfoxide (DMSO) to a final concentration of 5 mM. The conjugation was carried out in 1×PBS at antibody concentration of 1-30 mg/mL, DBCO compound to pAMF ratio of 1.5-3, and with 25% DMSO. The reaction mixture was incubated at room temperature for overnight. The conjugation efficiency was measured by LC/MS. Unconjugated DBCO compound was removed by cation exchange. The conjugate was formulated in formulation buffer supplemented with 9% sucrose. The drug to antibody ratio (DAR) was measured by LC/MS.
Thermal and colloidal stability of mAb 42 (HC 2188-D04 SEQ ID NO:895; LC SEQ ID NO:1021; unconjugated aROR1) and Conjugate 46 (aROR1 ADC) were measured by differential scanning fluorimetry (DSF) and dynamic light scattering (DLS), respectively. The values from these measurements are provided in Table 12. For the thermal stability of an antibody, the first melting peak (Tm1) coincides with the unfolding of the CH2 domain (FC stability), while the second melting peak (Tm2) occurs upon unfolding of the Fab domain. There is an improvement of FC stability after conjugation as the Tm1 shifts from 63.1° C. to 70.4° C., while the Fab stability (Tm2) remains stable.
For the colloidal stability of an antibody, the average particle radius (smaller radius=more tightly folded) and polydispersity (range of measured radii—an indicator of homogeneity) were measured in 1×PBS+10% sucrose buffer. While the radius and polydispersity did increase after conjugation, both measurements are within acceptable parameters (radius of an antibody is typically ˜5-6 nm, while polydispersity<15% is considered a homogeneous product) and indicate that Conjugate 46 is a well-behaved antibody in this buffer.
Stability assessment for Conjugate 46 and Conjugate 47 were evaluated under various stress conditions in several different formulation buffers. Study 1: Accelerated short term temperature stability was tested for signs of aggregation/degradation at 4° C., 25° C., and 37° C. and evaluated over a 2-week period. Study 2: Freeze/thaw stability was evaluated over five freeze/thaw cycles. Study 3: Determine the effect of protein aggregation induced through high concentrations at >40 mg/mL and prolonged hold times at 4° C. The formulations used in this study include:
As shown in
Five freeze/thaw cycles were performed on Conjugate 46 and Conjugate 47. After one, three, and five freeze/thaw cycles, an aliquot from both samples was assayed by A280 and HPLC-SEC. HPLC-SEC (

In vivo linker payload stability of four ROR1 ADC was investigated in non-tumor bearing C57BL/6 mice in a single dose study. Briefly, Conjugates 46, 47, 48, and 50 were injected through Ra at 5 mg/kg dose. Plasma samples were collected from 3 animals at 15 min, 3 days and 7 days after dosing and were kept frozen until ready to be analyzed. aROR1 ADC was pulled down from plasma using anti-hFc and then injected on to Agilent QToF for intact mass analysis. DAR was calculated based on deconvoluted peak area. As shown in
Anti-ROR1 antibody was conjugated to different linker-warheads described herein at different DARs and the cell killing activity of the ADCs were evaluated on ROR1 positive Ntera-2 cell and ROR1 negative MCF7 cells.
Ntera-2 or MCF7 cell at 625 cells/25 μL were seeded in a 384-well flat bottom white polystyrene plate one day before the assay start. ADCs were formulated at 2× starting concentration. Filter sterilized samples were serial diluted (1:3) under sterile conditions and added onto cells in triplicates. Plates were cultured at 37° C. in a CO2 incubator for 120 hours. For cell viability measurement, 30 microliter of Cell Titer-Glo® reagent (Promega Corp, Madison, WI) was added into each well, and plates processed as per product instructions. Relative luminescence was measured on an ENVISION® plate reader (Perkin-Elmer; Waltham, MA). Relative luminescence readings were converted to % viability using untreated cells as controls. Data was fitted with non-linear regression analysis, using log (inhibitor) vs. response, variable slope, 4-parameter fit equation using GraphPad Prism.
The cell killing EC50 and Span for ROR1 ADCs conjugated to different linker-warheads at different DARs on ROR1 positive Ntera-2 cell and ROR1 negative MCF7 cells are summarized in Tables 13-16.
To evaluate if the cell killing activity of anti-ROR1 ADCs is dependent on antibody binding to ROR1 expressed on cell surface, the same linker-warheads (LP3, LP4) were conjugated to an anti-GFP antibody and the cell killing of the anti-ROR1 and anti-GFP ADCs were evaluated in cell killing assays on ROR1 positive Ntera-2 cell and ROR1 negative MCF7 cells.
As shown in
The cell killing activity of the ROR1 ADCs on ROR1 positive Ntera-2 cells was also evaluated in the presence of un-conjugated anti-ROR1 antibody, which will compete with ADC on binding to the ROR1 antigen on the cell surface. As shown in
The activities of ROR1-targeted ADCs described herein were examined in a MDA-MB-231 TNBC xenograft model. Briefly, SCID/beige mice were implanted subcutaneously with 5×106 MDA-MB-231 tumor cells in the mammary fat pad and randomized and enrolled into the study 7 days post implant, with tumor sizes around 130 mm3. Tumor-bearing mice were administered four weekly doses (qw×4) of the test articles at doses ranging from 2 mg/kg to 5 mg/kg. All treatments were well tolerated with normal body weight gain throughout the course of the study.

SCID/beige mice were implanted subcutaneously with 5×106 MDA-MB-231 tumor cells in the mammary fat pad and randomized and enrolled into the study 11 days post implant, with tumor sizes around 120 mm3. Tumor-bearing mice were administered four weekly doses (qw×4) of the test articles at doses ranging from 1 mg/kg to 5 mg/kg. All treatments were well tolerated with normal body weight gain throughout the course of the study.
The activity of the ROR1-targeted ADCs was additionally examined in the H1975 NSCLC xenograft model. Briefly, SCID/beige mice were implanted subcutaneously with 5×106 H1975 tumor cells in the hind flank and randomized and enrolled into the study 7 days post implant, with tumor sizes around 100 mm3. Tumor-bearing mice were administered two weekly doses (qw×2) of the test articles at doses ranging from 1 mg/kg to 10 mg/kg. All treatments were well tolerated with normal body weight gain throughout the course of the study.
The activity of the different ROR1-targeted ADCs was additionally examined in NSCLC patient-derived xenograft (PDX) models. Briefly, PDX tumors, spanning varying levels of ROR1 expression, were passaged in athymic nude Fox1nu mice before being processed into tumor fragments for subcutaneous implantation into the hind flank of mice for study initiation. When tumors reached a volume of around 150-300 mm3, the mice were randomized and enrolled into the study. Tumor-bearing mice were administered up to five weekly doses (qw×5) of the test articles at 10 mg/kg. All treatments were well tolerated with normal body weight gain throughout the course of the study.
Table 19 provides mean TGI values reported for all molecules for each respective NSCLC PDX model when control tumors reached the study endpoint. Statistical analysis was performed on tumor volumes on the reported study day using one-way ANOVA with Dunnett's multiple comparisons test versus the vehicle group. A probability of less than 5% (p<0.05) was considered significant. *=p<0.05; **=p<0.01; ****=p<0.0001.
To understand the potential toxicity of the ROR1-targeted ADCs described herein prior to clinical development, drug toxicity in a non-human primate system, such as cynomolgus monkey, is tested. The ROR1-targeted ADCs described herein are dosed to cynomolgus monkeys in a repeat dose study (e.g, dosed twice, every 3 weeks) by slow intravenous infusion. The monkeys are dosed at different dose levels (e.g., 10 mg/kg, 20 mg/kg, or 45 mg/kg) to understand at which dose level toxicity occurs. Blood is drawn at various timepoints to monitor drug exposure and markers of toxicity. Ultimately, the ROR1-targeted ADCs' pharmacokinetic (PK) profile is aligned with observed toxicity to generate an understanding of the drug safety profile.
The PK profile of the drug is evaluated by measuring the component parts of an ADC: total antibody (Tab), drug-linker stability of the ADC (ADC), and free drug (free payload). Poor drug-linker stability or fast antibody clearance can contribute to drug catabolism and higher concentrations of free payload that cause toxicity. Blood clinical chemistry is evaluated to monitor for signs of liver or kidney toxicity. Blood hematology, such as various red and white blood cells, is also monitored to detect hematological toxicities. Both clinical chemistry and hematology are monitored over time to understand if toxicities are reversible.
The ADC and/or its component parts can also distribute into tissues, and therefore, have the potential to cause toxicity to specific organs. To understand tissue toxicities, animals are sacrificed at the end of the study (for example, 3 weeks following the second dose) and the organs are examined both macroscopically and microscopically for signs of drug injury. Specifically, organs are weighed and examined for differences in size, color, and/or appearance. To evaluate toxicities at the microscopic level, tissues are fixed, sectioned, and stained. Signs of microscopic injury may include mitotic arrest, necrotic or damaged tissues, and inflammation with or without signs of immune cell infiltration.
Drug safety can be partially represented by the drug's Highest Non-Severely Toxic Dose (HNSTD), or dose at which no or limited toxicities are observed. The higher the HNSTD, the more significant the drug safety.
The activity of Conjugate 46 as a single agent or in combination with the PARP inhibitor olaparib was additionally assessed in TNBC PDX models. Briefly, PDX tumors, spanning varying levels of ROR1 expression and sensitivity to olaparib, were passaged in athymic nude Fox1nu mice before being processed into tumor fragments for subcutaneous implantation into the hind flank of mice for study initiation. When tumors reached a volume of around 150-300 mm3, the mice were randomized and enrolled into the study. Tumor-bearing mice were administered up to three weekly doses (qw×3) of Conjugate 46 i.v. at 5 mg/kg and up to twenty-eight daily doses (qd×28) of olaparib p.o. at 50 mg/kg. All treatments were well tolerated, with mice exhibiting normal body weight gain throughout the course of the study.
Combination treatment with Conjugate 46 and olaparib (50 mg/kg, qd×28) is conducted using a 2 mg/kg, qw×3 dosing regimen for Conjugate 46. The combination therapy is assessed in six TNBC PDX models as described in Example 26.
ROR1-positive Ntera-2 cells were treated with Conjugate 46 or exatecan for 3 days. Calreticulin on the cell surface was measured by FACS and HMGB1 in the cell culture medium were measured by ELISA. Both Conjugate 46 and exatecan treatment induced markers for immunogenic cell death (calreticulin translocation to the cell surface and HMGB1 release into the cell culture medium).
ROR1-positive Ntera-2 cells were co-cultured with PMBCS at E:T=10.1 and treated with Conjugate 46 or exatecan for 3 days. Live target cell count and monocyte activation were measured by FACS. Both Conjugate 46 and exatecan treatment induced potent cell killing of target cells as well as monocyte activation.
The activity of Conjugate 46 as a single agent or in combination with anti-PD-1 was assessed in syngeneic models using a mouse lung cancer line engineered to express human ROR1, LLC1-hROR1. Briefly, C57BL/6 mice were implanted subcutaneously with 5×105 LLC1-hROR1 tumor cells in the hind flank and randomized and enrolled into the study 14 days post implant, with tumor sizes ranging from around 50 mm3 to 120 mm3. Tumor-bearing mice were administered two weekly doses (qw×2) of Conjugate 46 at 10 mg/kg and/or three doses (q3d×3) of the anti-PD-1 antibody at 8 mg/kg. All treatments were well tolerated, with mice exhibiting normal body weight gain throughout the course of the study. Two days after the final dose of Conjugate 46 (study day 9), the tumors were harvested and processed for immune phenotyping by flow cytometry.
