Methods of administering immunoconjugates that bind to CD37 (e.g., IMGN529) in combination with antibodies that bind to CD20 are provided. The methods comprise administering an anti-CD37 immunoconjugate (e.g., IMGN529) and an anti-CD20 antibody to a person in need thereof, for example, a cancer patient.

Anti-CD37 immunoconjugate and anti-CD20 antibody combinations

Novel anti-cancer agents, including, but not limited to, antibodies and immunoconjugates, that bind to CD37 are provided. Methods of using the agents, antibodies, or immunoconjugates, such as methods of inhibiting tumor growth are further provided.

CD37-binding molecules and immunoconjugates thereof

The invention generally relates to antibodies that bind to human CD37 and diagnostic assays for CD37-based therapies.

Antibodies and assays for detection of CD37

Methods of using CD37 agents, including, but not limited to, antibodies and immunoconjugates, that bind to CD37 to deplete B-cells (e.g., non-cancerous B-cells) and methods of treating autoimmune and inflammatory diseases are further provided.

Pharmaceutical composition comprising an antibody specifically recognizing CD38 and bortezomib.

Antitumors combinations containing antibodies recognizing specifically CD38 and bortezomib

CD20 is a transmembrane protein of the tetra-spanin family expressed on the surface of B-cells from peripheral blood as well as lymphoid tissues. CD20 expression persists from the early pre-B cell stage until the plasma cell differentiation stage. In addition to expression in normal B-cells, CD20 is expressed in B-cell derived malignancies such as non-Hodgkin's lymphoma (NHL) and B-cell chronic lymphocytic leukemia (CLL). The present invention includes anti-CD20 antibodies and antigen-binding fragments thereof comprising a light chain variable region and a heavy chain variable region, wherein the CDR-L1, CDR-L2, and CDR-L3 of said light chain variable region comprise the amino acid sequences of SEQ ID NOs: 17-19, respectively, and wherein the CDR-H1, CDR-H2, and CDR-H3 of said heavy chain variable region comprise the amino acid sequences of SEQ ID NOs: 20-22, respectively.

CD20 antibodies and uses thereof

CD20 is a transmembrane protein of the tetra-spanin family expressed on the surface of B-cells from peripheral blood as well as lymphoid tissues. CD20 expression persists from the early pre-B cell stage until the plasma cell differentiation stage. In addition to expression in normal B-cells, CD20 is expressed in B-cell derived malignancies such as non-Hodgkin's lymphoma (NHL) and B-cell chronic lymphocytic leukemia (CLL). The present invention includes anti-CD20 antibodies and antigen-binding fragments thereof comprising a light chain variable region and a heavy chain variable region, wherein the CDR-L1, CDR-L2, and CDR-L3 of said light chain variable region comprise the amino acid sequences of SEQ ID NOs: 23-25, respectively, and wherein the CDR-H1, CDR-H2, and CDR-H3 of said heavy chain variable region comprise the amino acid sequences of SEQ ID NOs: 26-28, respectively.

Antibodies, humanized antibodies, resurfaced antibodies, antibody fragments, derivatized antibodies, and conjugates of same with cytotoxic agents, which specifically bind to CD38, are capable of killing CD38cells by apoptosis, antibody-dependent cell-mediated cytotoxicity (ADCC), and/or complement-dependent cytotoxicity (CDC). Said antibodies and fragments thereof may be used in the treatment of tumors that express CD38 protein, such as multiple myeloma, chronic lymphocytic leukemia, chronic myelogenous leukemia, acute myelogenous leukemia, or acute lymphocytic leukemia, or the treatment of autoimmune and inflammatory diseases such as systemic lupus, rheumatoid arthritis, multiple sclerosis, erythematosus, and asthma. Said derivatized antibodies may be used in the diagnosis and imaging of tumors that express elevated levels of CD38. Also provided are cytotoxic conjugates comprising a cell binding agent and a cytotoxic agent, therapeutic compositions comprising the conjugate, methods for using the conjugates in the inhibition of cell growth and the treatment of disease, and a kit comprising the cytotoxic conjugate. In particular, the cell binding agent is a monoclonal antibody, and epitope-binding fragments thereof, that recognizes and binds the CD38 protein.
