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. 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.

L'invention concerne des anticorps, des anticorps humanisés, des anticorps resurfacés, des fragments d'anticorps, des anticorps dérivatisés, et des conjugués de ceux-ci et d'agents cytotoxiques, qui se lient de manière spécifique au CD38, sont capables d'éliminer des cellules de CD38+ par apoptose, cytotoxicité à médiation cellulaire dépendante de l'anticorps (ADCC), et/ou cytotoxicité dépendante du complément (CDC). Lesdits anticorps et fragments de ceux-ci peuvent être utilisés dans le traitement de tumeurs qui expriment la protéine CD38, de type myélome multiple, leucémie lymphoïde chronique, leucémie myéloïde chronique, leucémie myéloïde aiguë, ou leucémie lymphoïde aiguë, ou dans le traitement de maladies auto-immunes et inflammatoires de type lupus érythémateux systémique, polyarthrite rhumatoïde, sclérose en plaques, troubles érythémateux, et asthme. Lesdits anticorps dérivatisés peuvent être utilisés dans le diagnostic et l'imagerie de tumeurs qui expriment des niveaux élevés de CD38. L'invention concerne également des conjugués cytotoxiques qui comprennent un agent de liaison aux cellules et un agent cytotoxique, des compositions thérapeutiques qui comprennent ledit conjugué, des méthodes d'utilisation des conjugués dans l'inhibition de la croissance cellulaire et le traitement de maladies, et un kit qui comprend ledit conjugué cytotoxique. En particulier, l'agent de liaison aux cellules est un anticorps monoclonal, et des fragments de liaison aux épitotes de celui-ci, qui reconnaîssent la protéine CD38 et qui se lient à celle-ci.
