CA 2457541

Methods and compositions for the development of effective cancer therapies using mitotic inhibitors which have limited general toxicity to normal, non- cancerous cells and tissues are provided. The methods and compositions utilize cytotoxic compounds comprised of a cell-binding agent (e.g., antibodies) conjugated to an anti-mitotic compound (e.g., maytansinoids). The invention further provides antibodies which are substantially incapable of inducing antibody-dependent cell-mediated cytotoxicity (ADCC) and/or complement dependent cytotoxicity (CDC), thereby ensuring that the therapeutic effect is mediated primarily by the anti-mitotic component of the cytotoxic compound, rather than by indirect cell killing via ADCC and/or CDC. The antibodies of the invention further are capable of differentiating between polypeptide antigens which are more highly expressed on proliferating cancer cells as compared to proliferating non-cancer cells.

L'invention concerne des méthodes et des compositions destinées au développement de thérapies anticancéreuses efficaces, au moyen d'inhibiteurs mitotiques qui présentent une toxicité générale limitée à l'égard de cellules et de tissus non cancéreux, normaux. Ces méthodes et ces compositions emploient des composés cytotoxiques comprenant un agent de liaison cellulaire (par exemple, des anticorps) conjugué à un composé antimitotique (par exemple, des maytansinoides). Ladite invention a également trait à des anticorps qui sont pratiquement incapables d'induire une cytotoxicité à médiation cellulaire dépendante des anticorps (ADCC) et/ou une cyctotoxicité dépendante du complément (CDC), ce qui permet de garantir que l'effet thérapeutique repose, principalement, sur une médiation effectuée par le composé antimitotique du composé cytotoxique, plutôt que par la destruction cellulaire indirecte via ADCC et/ou CDC. Les anticorps de cette invention peuvent, en outre, réaliser une différenciation entre des antigènes de polypeptides, qui sont beaucoup plus exprimés dans des cellules cancéreuses prolifératives que dans des cellules non cancéreuses prolifératives.
