Abstract: Antibodies, humanized antibodies, resurfaced antibodies, antibody fragments, derivatized antibodies, and conjugates of same with cytotoxic agents, which specifically bind to, and inhibit A class of Eph receptors, antagonize the effects of growth factors on the growth and survival of tumor cells, and which have minimal agonistic activity or are preferentially devoid of agonist activity. Said antibodies and fragments thereof may be used in the treatment of tumors that express elevated levels of A class of Eph receptors, such as breast cancer, colon cancer, lung cancer, ovarian carcinoma, synovial sarcoma and pancreatic cancer, and said derivatized antibodies may be used in the diagnosis and imaging of tumors that express elevated levels of A class of Eph receptors.

Abstract: 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 CD38+ cells 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.

Abstract: The present invention encompasses manufacturing of antibody variants, such as variant of huC242, or fragments thereof, wherein the variants are manufactured by substituting one or more amino acid residues in a parent antibody. Such substitution(s) is preferably done in a variable region framework sequence of the parent antibody comprising a heavy and a light chain. As a consequence of such substitution(s), variant antibodies or fragments thereof show enhanced antibody synthesis when introduced in a host cell as compared to the parent antibody.
