[0005] The contents of the electronic sequence listing (146392054640SEQLIST.xml; size: 75,734 bytes; and creation date: August 4, 2022) are incorporated herein by reference in their entirety. Technical Field
[0006] The present disclosure relates to methods of treating B-cell proliferative disorders, such as diffuse large B-cell lymphoma (DLBCL), by administering an immunoconjugate comprising an anti-CD79b antibody in combination with an anti-CD20 antibody, one or more chemotherapeutic agents, and a corticosteroid. Background Art
[0007] Non-Hodgkin lymphoma (NHL) is the most common hematological malignancy worldwide and ranks 13th among the most common cancers overall (Bray et al., (2018) CA Cancer J Clin, 68:394-424). Diffuse large B-cell lymphoma (DLBCL) is an aggressive subtype of NHL, accounting for approximately 32.5% of all NHL cases. Patients with DLBCL present with rapidly enlarging masses, often accompanied by local and systemic symptoms of fever, recurrent night sweats and / or weight loss. Approximately 45% to 60% of patients have advanced disease (Ann Arbor stage III or IV). The incidence of DLBCL increases with age, with a median age of 64 years at onset (Armitage and Weisenburger, J Clin Oncol (1998) 6:2780-95). If untreated, patients with DLBCL have a median survival of approximately 6 months.
[0008] More than 20 years ago, rituximab plus cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP) was determined to be the standard of care (SoC) therapy for DLBCL. The method for improving the current SoC therapy for DLBCL has been largely unsuccessful. These methods include attempting to maximize the dose density of R-CHOP (Cunningham et al., Lancet (2013) 381: 1817-26; Delarue et al., Lancet Oncol (2013) 14: 525-33), and experimental treatments, such as those tested in large studies of DLBCL, including BO21005 / GOYA (Vitolo et al., Blood (2016) 128: 470), DA-EPOCH-R (Wilson et al., Blood (2016) 128: 469) and REMAC (Thieblemont et al., Blood (2016) 128: 471). Overall, since R-CHOP was established as a SoC therapy for DLBLC, 11 randomized phase III studies have failed to show any benefit compared with R-CHOP in first-line DLBCL.
[0009] For patients who are not cured by the therapy for previously untreated DLBCL, high-dose chemotherapy and subsequent autologous stem cell transplantation provide a second chance of cure. However, about half of these patients do not respond to subsequent therapy due to refractory disease (Gisselbrecht et al., J Clin Oncol (2010) 28: 4184-90), and a considerable number of patients do not meet the conditions of this radical therapy due to age or comorbidities. Patients who relapse after stem cell transplantation or do not meet the conditions of stem cell transplantation due to refractory disease or weakness have poor results. In most cases, the response rate to subsequent therapy is within the range of 10% to 35% (Seyfarth et al., Br J Haematol (2006) 133 (1): 3-18), with only occasional persistent responses. The fact that most patients who are not cured by standard first-line R-CHOP or comparable chemoimmunotherapy will die of lymphoma highlights the need for new methods for first-line therapy of this aggressive disease.
[0010] Therefore, there is a need in the art for new treatment methods for patients with DLBCL, such as previously untreated DLBCL.

Such techniques are fully explained in the following documents, such as "Molecular Cloning: A Laboratory Manual", Second Edition (Sambrook et al., 1989); "Oligonucleotide Synthesis" (MJ Gait compiles, 1984); "Animal Cell Culture" (RI Freshney compiles, 1987); "Methods in Enzymology" (Academic Press, Inc.); "Current Protocols in Molecular Biology" (FM Ausubel et al. compiles, 1987, and regularly updated); "PCR: The Polymerase Chain Reaction" (Mullis et al. compiles, 1994); "A Practical Guide to Molecular Cloning" (Perbal Bernard V., 1988); "Phage Display: A Laboratory Manual" (Barbas et al., 2001).
[0122] II. Definitions
[0123] Before describing the present invention in detail, it should be understood that the present invention is not limited to specific compositions or biological systems, which can certainly vary. Additionally, it should be understood that the terminology used herein is for the purpose of describing specific embodiments only and is not intended to be limiting.
[0124] As used in this specification and the appended claims, the singular forms "a," "an," and "the" include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to "a molecule" optionally includes a combination of two or more such molecules, and so forth.
[0125] As used herein, the term "about" refers to the common error range of the corresponding value that is readily known to those skilled in the art. References to "about" values or parameters herein include (and describe) embodiments involving the value or parameter itself.
[0126] It should be understood that aspects and embodiments of the invention described herein include aspects and embodiments referred to as "comprising," "consisting of," and "consisting essentially of."
[0127] Unless otherwise indicated, as used herein, the term "CD79b" refers to any natural CD79b from any vertebrate source, including mammals such as primates (e.g., humans, cynomolgus monkeys ("cyno")) and rodents (e.g., mice and rats). Human CD79b is also referred to herein as "Igβ," "B29," "DNA225786," or "PRO36249." An exemplary CD79b sequence comprising a signal sequence is shown in SEQ ID NO: 1. An exemplary CD79b sequence without a signal sequence is shown in SEQ ID NO: 2. The term "CD79b" encompasses "full-length" unprocessed CD79b, as well as any form of CD79b produced by processing in cells. The term also encompasses naturally occurring variants of CD79b, e.g., splice variants, allelic variants, and isoforms. The CD79b polypeptides described herein can be isolated from a variety of sources, such as from human tissue types or other sources, or prepared by recombinant or synthetic methods. "Native sequence CD79b polypeptides" include polypeptides having the same amino acid sequence as the corresponding CD79b polypeptides derived from nature. Such native sequence CD79b polypeptides can be isolated from nature or produced by recombinant or synthetic means. The term "native sequence CD79b polypeptide" specifically encompasses naturally occurring truncated or secreted forms (e.g., extracellular domain sequences), naturally occurring variant forms (e.g., alternatively spliced forms), and naturally occurring allelic variants of a particular CD79b polypeptide.
[0128] As used herein, "CD20" refers to the human B lymphocyte antigen CD20 (also known as CD20, B lymphocyte surface antigen B1, Leu-16, Bp35, BM5, and LF5; the sequence is characterized by SwissProt database entry P11836), which is a hydrophobic transmembrane protein with a molecular weight of approximately 35 kD located on pre-B and mature B lymphocytes. (Valentine, MA et al., J. Biol. Chem. 264 (19) (1989 11282-11287; Tedder, TF et al., Proc. Natl. Acad. Sci. USA 85 (1988) 208-12; Stamenkovic, I. et al., J. Exp. Med. 167 (1988) 1975-80; Einfeld, DA et al., EMBO J. 7 (1988) 711-7; Tedder, TF et al., J. Immunol. 142 (1989) 2560-8). The corresponding human gene is transmembrane 4 domain, subfamily A member 1, also known as MS4A1. This gene encodes a member of the transmembrane 4A gene family. Members of this family of new proteins are characterized by common structural features and similar intron / exon splicing boundaries and exhibit distinct expression patterns in hematopoietic cells and non-lymphoid tissues. This gene encodes a B lymphocyte surface molecule that plays a role in the development and differentiation of B cells into plasma cells. This family member is located in a cluster of family members at 11q12. Alternative splicing of this gene produces two transcript variants encoding the same protein.
[0129] The terms "CD20" and "CD20 antigen" are used interchangeably herein and include any variants, isoforms, and species homologs of human CD20 that are naturally expressed by cells or expressed on cells transfected with the CD20 gene. Binding of the antibodies of the present invention to the CD20 antigen mediates killing of cells expressing CD20 (e.g., tumor cells) by inactivating CD20. Killing of cells expressing CD20 can occur through one or more of the following mechanisms: cell death / apoptosis induction, ADCC, and CDC. As recognized in the art, aliases for CD20 include B lymphocyte antigen CD20, B lymphocyte surface antigen B1, Leu-16, Bp35, BM5, and LF5.
[0130] The term "expression of the CD20 antigen" is intended to mean the expression of a significant level of the CD20 antigen in a cell (e.g., a T cell or a B cell). In one embodiment, a patient to be treated according to the methods of the present invention expresses significant levels of CD20 on a B cell tumor or cancer. Patients with "CD20-expressing cancers" can be determined by standard assays known in the art. For example, CD20 antigen expression is measured using immunohistochemistry (IHC) assays, FACS, or detection of the corresponding mRNA via PCR-based assays.
[0131] "Affinity" refers to the strength of the sum of the non-covalent interactions between a single binding site of a molecule (e.g., an antibody) and its binding partner (e.g., an antigen). Unless otherwise indicated, as used herein, "binding affinity" refers to intrinsic binding affinity, which reflects a 1:1 interaction between members of a binding pair (e.g., an antibody and an antigen). The affinity of a molecule X for its partner Y can generally be represented by a dissociation constant (Kd). Affinity can be measured by conventional methods known in the art, including those described herein. Specific illustrative and exemplary embodiments for measuring binding affinity are described below.
[0132] An "affinity matured" antibody is one with one or more alterations in one or more hypervariable regions (HVRs) which result in an improvement in the affinity of the antibody for antigen, compared to a parent antibody which does not possess such alteration(s).
[0133] The term "antibody" herein is used in the broadest sense and encompasses various antibody structures, including but not limited to monoclonal antibodies, polyclonal antibodies, multispecific antibodies (e.g., bispecific antibodies), and antibody fragments, so long as they exhibit the desired antigen-binding activity.
[0134] "Antibody fragments" refer to molecules other than intact antibodies that comprise a portion of an intact antibody and bind to the antigen to which the intact antibody binds. Examples of antibody fragments include, but are not limited to, Fv, Fab, Fab', Fab'-SH, F(ab')2; diabodies; linear antibodies; single-chain antibody molecules (e.g., scFv); and multispecific antibodies formed from antibody fragments.
[0135] An "antibody that binds to the same epitope as a reference antibody" is an antibody that blocks the binding of the reference antibody to its antigen by 50% or more in a competition assay, whereas the reference antibody blocks the binding of the antibody to its antigen by 50% or more in a competition assay. An exemplary competition assay is provided herein.
[0136] The term "epitope" refers to a specific site on an antigen molecule to which an antibody binds.
[0137] 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.
[0138] The "class" of an antibody refers to the type of constant domain or region possessed by its heavy chain. There are five major classes of antibodies: IgA, IgD, IgE, IgG, and IgM, and some of these antibodies can be further divided into subclasses (isotypes), such as IgG1, IgG2, IgG3, IgG4, IgA1, and IgA2. The heavy chain constant domains corresponding to the different classes of immunoglobulins are called α, δ, ε, γ, and μ, respectively.
[0139] The terms "anti-CD79b antibody" and "antibody that binds to CD79b" refer to an antibody that is capable of binding to CD79b with sufficient affinity so that the antibody can be used as a diagnostic and / or therapeutic agent targeting CD79b. Preferably, the degree of binding of the anti-CD79b antibody to unrelated, non-CD79b proteins is less than about 10% of the degree of binding of the antibody to CD79b, as measured, for example, by radioimmunoassay (RIA). In certain embodiments, the antibody that binds to CD79b has a dissociation constant (Kd) of ≤1 μM, ≤100 nM, ≤10 nM, ≤1 nM, or ≤0.1 nM. In certain embodiments, the anti-CD79b antibody binds to an epitope of CD79b that is conserved among CD79b from different species.
[0140] The term "anti-CD20 antibody" according to the present invention refers to an antibody that binds to CD20 with sufficient affinity so that the antibody can be used as a diagnostic and / or therapeutic agent targeting CD20. Preferably, the extent of binding of the anti-CD20 antibody to unrelated, non-CD20 proteins is less than about 10% of the extent of binding of the antibody to CD20, as measured, for example, by radioimmunoassay (RIA). In certain embodiments, the antibody binds to CD20 with a dissociation constant (Kd) of ≤1 μM, ≤100 nM, ≤10 nM, ≤1 nM, or ≤0.1 nM. In certain embodiments, the anti-CD20 antibody binds to an epitope of CD20 that is conserved among CD20 from different species.
[0141] "Isolated" antibodies are antibodies that have been separated from the components of their natural environment. In some embodiments, the antibody is purified to a purity greater than 95% or 99% as determined by, for example, electrophoresis (e.g., SDS-PAGE, isoelectric focusing (IEF), capillary electrophoresis) or chromatography (e.g., ion exchange or reversed-phase HPLC). For a review of methods for assessing antibody purity, see, for example, Flatman et al., J. Chromatogr. B 848:79-87 (2007). The "variable region" or "variable domain" of an antibody refers to the amino terminal domain of the heavy or light chain of an antibody. The variable domain of the heavy chain may be referred to as "VH." The variable domain of the light chain may be referred to as "VL." These domains are typically the most variable parts of an antibody and contain the antigen binding site.
[0142] "Isolated nucleic acid encoding an anti-CD79b antibody" refers to one or more nucleic acid molecules encoding the antibody heavy and light chains (or fragments thereof), including such nucleic acid molecules in a single vector or separate vectors, and such nucleic acid molecules present in one or more locations in a host cell.
[0143] As used herein, the term "monoclonal antibody" refers to the antibody obtained from a substantially homogeneous antibody population, that is, except possible variant antibodies (for example, containing naturally occurring mutations or producing during the production of monoclonal antibody preparations, such variants are generally present in a small amount), the individual antibodies comprising the population are identical and / or in conjunction with identical epi-positions. Contrary to the polyclonal antibody preparations typically comprising different antibodies for different determinants (epi-positions), each monoclonal antibody in the monoclonal antibody preparation is directed to a single determinant on the antigen. Therefore, the modifier "monoclonal" represents that the feature of an antibody is obtained from a substantially homogeneous antibody population, and should not be construed as needing to produce an antibody by any ad hoc method. For example, the monoclonal antibody to be used according to the present invention can be prepared by various techniques, including but not limited to hybridoma method, recombinant DNA method, phage display method and the method utilizing a transgenic animal containing all or part of a human immunoglobulin locus, and such methods and other exemplary methods for the preparation of monoclonal antibodies are described herein.
[0144] A "naked antibody" is an antibody that is not conjugated to a heterologous moiety (eg, a cytotoxic moiety) or a radiolabel. Naked antibodies can be present in pharmaceutical formulations.
[0145] "Natural antibodies" refer to naturally occurring immunoglobulin molecules with different structures. For example, natural IgG antibodies are heterotetrameric glycoproteins of approximately 150,000 daltons, consisting of two identical light chains and two identical heavy chains bound by disulfide bonds. From the N-terminus to the C-terminus, each heavy chain has a variable region (VH), also referred to as a variable heavy chain domain or a heavy chain variable domain, followed by three constant domains (CH1, CH2, and CH3). Similarly, from the N-terminus to the C-terminus, each light chain has a variable region (VL), also referred to as a variable light chain domain or a light chain variable domain, followed by a constant light chain (CL) domain. The light chain of an antibody can be classified into one of two types, called kappa (κ) and lambda (λ), based on the amino acid sequence of its constant domain.
[0146] The term "Fc region" herein is used to define the C-terminal region of an immunoglobulin heavy chain, which comprises at least a portion of a constant region. The term includes native sequence Fc regions and variant Fc regions. In one embodiment, the human IgG heavy chain Fc region extends from Cys226 or from Pro230 to the carboxyl terminus of the heavy chain. However, the C-terminal lysine (Lys447) in the Fc region may be present or absent. Unless otherwise indicated herein, the numbering of amino acid residues in the Fc region or constant region is according to the EU numbering system, also referred to as the EU index, as described by Kabat et al. (Sequences of Proteins of Immunological Interest, 5th Edition, Public Health Service, National Institutes of Health, Bethesda, MD, 1991).
[0147] "Framework" or "FR" refers to the variable domain residues excluding the hypervariable region (HVR) residues. The FR of a variable domain is typically composed of the following four FR domains: FR1, FR2, FR3, and FR4. Thus, the HVR and FR sequences typically appear in the following sequence in VH (or VL): FR1-H1(L1)-FR2-H2(L2)-FR3-H3(L3)-FR4.
[0148] For the purposes of this paper, an "acceptor human framework" is a framework comprising an amino acid sequence of a light chain variable domain (VL) framework or a heavy chain variable domain (VH) framework derived from a human immunoglobulin framework or a human consensus framework as defined below. An acceptor human framework "derived from" a human immunoglobulin framework or a human consensus framework may comprise an amino acid sequence identical to that of the human immunoglobulin framework or the human consensus framework, or it may comprise amino acid sequence changes. In some embodiments, the number of amino acid changes is 10 or less, 9 or less, 8 or less, 7 or less, 6 or less, 5 or less, 4 or less, 3 or less, or 2 or less. In some embodiments, the VL acceptor human framework is identical in sequence to the VL human immunoglobulin framework sequence or the human consensus framework sequence.
[0149] The terms "full length antibody," "intact antibody," and "whole antibody" are used interchangeably herein to refer to an antibody that has a structure substantially similar to a native antibody structure or has heavy chains that contain an Fc region as defined herein.
[0150] The terms "host cell," "host cell line," and "host cell culture" are used interchangeably and refer to cells into which exogenous nucleic acid has been introduced, including the progeny of such cells. Host cells include "transformants" and "transformed cells," which include the primary transformed cell and progeny derived from the primary transformed cell, regardless of the number of passages. Progeny may not be identical to the nucleic acid content of the parent cell but may contain mutations. Mutant progeny that have the same function or biological activity as screened or selected in the original transformed cell are included herein.
[0151] A "human antibody" is an antibody that possesses an amino acid sequence that corresponds to the amino acid sequence of an antibody produced by a human or human cell, or derived from a non-human source utilizing a repertoire of human antibodies or other human antibody coding sequences. This definition of a human antibody specifically excludes humanized antibodies comprising non-human antigen-binding residues.
[0152] A "human consensus framework" is a framework that represents the most commonly occurring amino acid residues in a selection of human immunoglobulin VL or VH framework sequences. Typically, the selection of human immunoglobulin VL or VH sequences is from a subset of variable domain sequences. Typically, the subset of sequences is a subset as described in Kabat et al., Sequences of Proteins of Immunological Interest, Fifth Edition, NIH Publication 91-3242, Bethesda MD (1991), Volumes 1-3. In one embodiment, for VL, the subset is subgroup κI as described in Kabat et al., supra. In one embodiment, for VH, the subset is subgroup III as described in Kabat et al., supra.
[0153] A "humanized" antibody refers to a chimeric antibody comprising amino acid residues from non-human HVRs and amino acid residues from human FRs. In certain embodiments, a humanized antibody will comprise substantially all of at least one, typically two, variable domains, wherein all or substantially all of the HVRs (e.g., CDRs) correspond to the HVRs of a non-human antibody, and all or substantially all of the FRs correspond to the FRs of a human antibody. A humanized antibody optionally may comprise at least a portion of an antibody constant region derived from a human antibody. A "humanized form" of an antibody, e.g., a non-human antibody, refers to an antibody that has been humanized.
[0154] As used herein, the term "hypervariable region" or "HVR" refers to each region in the antibody variable domain region that is highly variable in sequence and / or forms structurally defined loops ("hypervariable loops"). Typically, a natural four-chain antibody comprises six HVRs: three in VH (H1, H2, H3) and three in VL (L1, L2, L3). HVRs typically comprise amino acid residues from hypervariable loops and / or from "complementarity determining regions" (CDRs), which have the highest sequence variability and / or are involved in antigen recognition. Exemplary hypervariable loops occur at amino acid residues 26 to 32 (L1), 50 to 52 (L2), 91 to 96 (L3), 26 to 32 (H1), 53 to 55 (H2), and 96 to 101 (H3) (Chothia and Lesk, J. Mol. Biol. 196:901-917 (1987)). Exemplary CDRs (CDR-L1, CDR-L2, CDR-L3, CDR-H1, CDR-H2, and CDR-H3) occur at amino acid residues 24 to 34 of L1, 50 to 56 of L2, 89 to 97 of L3, 31 to 35B of H1, 50 to 65 of H2, and 95 to 102 of H3 (Kabat et al., Sequences of Proteins of Immunological Interest, 5th ed., Public Health Service, National Institutes of Health, Bethesda, MD (1991)). Except for CDR1 in VH, CDRs generally comprise amino acid residues that form hypervariable loops. CDRs also comprise "specificity determining residues" or "SDRs," which are residues that make contact with the antigen. SDRs are contained within CDR regions known as shortened CDRs or α-CDRs. Exemplary α-CDRs (α-CDR-L1, α-CDR-L2, α-CDR-L3, α-CDR-H1, α-CDR-H2, and α-CDR-H3) appear at amino acid residues 31 to 34 of L1, amino acid residues 50 to 55 of L2, amino acid residues 89 to 96 of L3, amino acid residues 31 to 35B of H1, amino acid residues 50 to 58 of H2, and amino acid residues 95 to 102 of H3. See Almagro and Fransson, Front. Biosci. 13: 1619-1633 (2008). Unless otherwise indicated, HVR residues and other residues in the variable domain (e.g., FR residues) are numbered herein according to Kabat et al. (supra).
[0155] The term "variable region" or "variable domain" refers to the domain of an antibody heavy chain or light chain that participates in binding of an antibody to an antigen. The variable domains of the heavy and light chains of natural antibodies (VH and VL, respectively) generally have similar structures, wherein each domain comprises four conserved framework regions (FR) and three hypervariable regions (HVR) (see, e.g., Kindt et al. Kuby Immunology, 6th edition, WH Freeman and Co., p. 91 (2007)). A single VH or VL domain may be sufficient to confer antigen binding specificity. In addition, antibodies that bind to a specific antigen can be isolated using the VH or VL domains from antibodies that bind to the antigen, respectively, to screen for libraries of complementary VL or VH domains. See, e.g., Portolano et al., J. Immunol. 150: 880-887 (1993); Clarkson et al., Nature 352: 624-628 (1991).
[0156] "Effector functions" refer to those biological activities attributable to the Fc region of an antibody, which vary with the antibody isotype. Examples of antibody effector functions include: C1q binding and complement-dependent cytotoxicity (CDC); Fc receptor binding; antibody-dependent cell-mediated cytotoxicity (ADCC); phagocytosis; downregulation of cell surface receptors (e.g., B cell receptor); and B cell activation.
[0157] "Percentage (%) of amino acid sequence identity relative to a reference polypeptide sequence is defined as the percentage of amino acid residues in the candidate sequence that are identical to the amino acid residues in the reference polypeptide sequence after aligning the candidate sequence with the reference polypeptide sequence and introducing gaps (if necessary) to achieve maximum sequence identity, and without considering any conservative substitutions as components of sequence identity. Alignment for determining percentages of amino acid sequence identity can be achieved in various ways within the skill of the art, for example, using publicly available computer software such as BLAST, BLAST-2, ALIGN or Megalign (DNASTAR) software. Those skilled in the art can determine appropriate parameters for aligning sequences, including any algorithm required for achieving maximum alignment over the full length of the compared sequences. However, for the purposes of this article, the sequence comparison computer program ALIGN-2 is used to generate values for % amino acid sequence identity. The ALIGN-2 sequence comparison computer program was written by Genentech, Inc., and the source code has been submitted to the US Copyright Office, Washington DC, 20559, along with user documentation, where it is registered with U.S. Copyright Registration No. TXU510087. The ALIGN-2 program is publicly available from Genentech, Inc. (South San Francisco, California) or can be compiled from the source code. The ALIGN-2 program should be compiled for use on a UNIX operating system, including digital UNIX V4.0D. All sequence comparison parameters are set by the ALIGN-2 program and do not change.
[0158] In the case of amino acid sequence comparison using ALIGN-2, the % amino acid sequence identity between a given amino acid sequence A and a given amino acid sequence B (which can alternatively be expressed as the % that a given amino acid sequence A has or contains a certain amino acid sequence identity with a given amino acid sequence B) is calculated as follows:
[0159] Multiply 100 by the fraction X / Y
[0160] where X is the number of amino acid residues scored as identical matches by the sequence alignment program ALIGN-2 in that program's alignment of A and B, and where Y is the total number of amino acid residues in B. It will be understood that where the length of amino acid sequence A is not equal to the length of amino acid sequence B, the % amino acid sequence identity of A to B will not equal the % amino acid sequence identity of B to A. Unless specifically stated otherwise, all % amino acid sequence identity values used herein are obtained using the ALIGN-2 computer program as described in the preceding paragraph.
[0161] As used herein, the term "vector" refers to a nucleic acid molecule capable of transporting another nucleic acid to which it is linked. The term includes vectors that are self-replicating nucleic acid structures, as well as vectors that are incorporated into the genome of a host cell into which they have been introduced. Certain vectors are capable of directing the expression of nucleic acids to which they are operably linked. Such vectors are referred to herein as "expression vectors."
[0162] An "immunoconjugate" is an antibody conjugated to one or more heterologous molecules, including but not limited to a cytotoxic agent.
[0163] In the context of the formulae provided herein, "p" refers to the average number of drug moieties per antibody, which can range, for example, from about 1 to about 20 drug moieties per antibody, and in certain embodiments, from 1 to about 8 drug moieties per antibody.

[0164] As used herein, the term "cytotoxic agent" refers to a substance that inhibits or prevents cell function and / or causes cell death or destruction. Cytotoxic agents include, but are not limited to, radioactive isotopes (e.g., At 211 , I 131 , I 125 、Y 90 、Re 186 、Re 188 、Sm 153 、Bi 212 、P 32 , Pb 212 and radioisotopes of Lu); chemotherapeutic agents or drugs (e.g., methotrexate, doxorubicin, vinca alkaloids (vincristine, vinblastine, etoposide), doxorubicin, melphalan, mitomycin C, chlorambucil, daunorubicin or other intercalating agents); growth inhibitors; enzymes and fragments thereof such as nucleolytic enzymes; antibiotics; toxins such as small molecule toxins or enzymatically active toxins of bacterial, fungal, plant or animal origin, including fragments and / or variants thereof; and various anti-tumor or anti-cancer drugs disclosed below.
[0165] The terms "cancer" and "cancerous" refer to or describe the physiological condition in mammals that is typically characterized by unregulated cell growth. Examples of cancer include, but are not limited to, B-cell lymphomas (including low-grade / follicular non-Hodgkin's lymphoma (NHL); small lymphocytic (SL) NHL; intermediate-grade / follicular NHL; intermediate-grade diffuse NHL; high-grade immunoblastic NHL; high-grade lymphocytic NHL; high-grade small non-cleaved cell NHL; bulky lesion NHL; mantle cell lymphoma; AIDS-related lymphoma; and Waldenstrom's macroglobulinemia); chronic lymphocytic leukemia (CLL); acute lymphocytic leukemia (ALL); hairy cell leukemia; chronic myeloid leukemia; and post-transplant lymphoproliferative disorder (PTLD); as well as abnormal vascular proliferation associated with nevus hamartomatosis, edema (such as that associated with brain tumors), and Meigs' syndrome.

[0211] "Enantiomers" refer to two stereoisomers of a compound that are non-superimposable mirror images of one another.
[0212] The stereochemical definitions and conventions used herein generally follow: SP Parker, ed., McGraw-Hill Dictionary of Chemical Terms (1984) McGraw-Hill Book Company, New York; and Eliel, E. and Wilen, S., Stereochemistry of Organic Compounds (1994) John Wiley & Sons, Inc., New York. Many organic compounds exist in optically active forms, i.e., they have the ability to rotate the plane of plane-polarized light. When describing optically active compounds, the prefixes D and L or R and S are used to indicate the absolute configuration of the molecule around its chiral center. The prefixes d and 1 or (+) and (-) are used to indicate the sign of the rotation of the compound with respect to plane-polarized light, where (-) or 1 indicates that the compound is left-handed. Compounds with the (+) or d prefix are right-handed. For a given chemical structure, these stereoisomers are identical except that they are mirror images of each other. Specific stereoisomers may also be referred to as enantiomers, and mixtures of such isomers are often referred to as enantiomeric mixtures. A 50:50 mixture of enantiomers is called a racemic mixture or racemate, which may occur in the absence of stereoselectivity or stereospecificity in a chemical reaction or process. The terms "racemic mixture" and "racemate" refer to an equimolar mixture of two enantiomeric species that are not optically active.
[0213] A "leaving group" refers to a functional group that can be replaced by another functional group. Certain leaving groups are well known in the art, and examples include, but are not limited to, halides (e.g., chloride, bromide, iodide), methylsulfonyl (mesyl), p-toluenesulfonyl (tosyl), trifluoromethylsulfonyl (triflate), and triflate.
[0214] The term "blocking group" refers to a substituent that is typically used to block or protect a specific functional group while reacting with other functional groups on a compound. For example, an "amino protecting group" is a substituent attached to an amino group that blocks or protects the amino functional group in the compound. Suitable amino protecting groups include, but are not limited to, acetyl, trifluoroacetyl, tert-butyloxycarbonyl (BOC), benzyloxycarbonyl (CBZ) and 9-fluorenylmethyleneoxycarbonyl (Fmoc). For general information about blocking groups and their uses, see TW Greene, Protective Groups in Organic Synthesis, John Wiley & Sons, New York, 1991 or later.

[0305] In some embodiments, progression-free survival (PFS) or the absence of disease progression is assessed as the time from the start of treatment according to the methods provided herein (e.g., any one of 7 days, 6 days, 5 days, 4 days, 3 days, 2 days, 1 day, or 0 days) to the first occurrence of disease progression or relapse, or the time of death from any cause. In some embodiments, PFS or the absence of disease progression is assessed from the randomization date of the treatment regimen described in Example 1 to the first occurrence of disease progression or relapse, or the time of death from any cause. In some embodiments, disease progression or relapse is assessed by the investigator using the 2014 Lugano Classification of Malignant Lymphoma (Cheson et al., 2014). In some embodiments, for individuals who have not progressed, relapsed, or died by the clinical analysis cutoff date, PFS is censored on the last disease assessment date at which the individual is known to have no progression. In some embodiments, if no tumor assessment is performed after baseline or all post-baseline tumor assessment results have an overall response of "not evaluable", PFS is censored up to 7 days (e.g., any one of 7 days, 6 days, 5 days, 4 days, 3 days, 2 days, 1 day, or 0 days) before starting treatment according to the methods provided herein (e.g., on the randomization date according to the treatment regimen described in Example 1).
