Abstract

Disclosed herein are human monoclonal antibodies that specifically bind both IGF-I and IGF-II with picomolar affinity and potently inhibit the IGF-IR signal transduction function. These antibodies are active in both an IgG and a scFv format. Bispecific forms of these antibodies are also disclosed. Nucleic acids encoding these antibodies, vectors including these nucleic acids, and host cells transformed with these vectors are also disclosed herein. Also disclosed are pharmaceutical compositions including these antibodies. Methods are provided for treating a subject with cancer and for inhibiting phosphorylation of the insulin-like growth factor-I receptor. Methods are also provided for diagnosing cancer. | La présente invention concerne des anticorps monoclonaux humains qui se lient spécifiquement à la fois à IGF-I et IGF-II avec une affinité de l'ordre du picomolaire et qui inhibent puissamment la fonction de transduction de signal du récepteur d'IGF-I. Ces anticorps sont actifs dans le format IgG et dans le format scFv. L'invention concerne également des formes bispécifiques de ces anticorps. L'invention concerne également des acides nucléiques codant pour ces anticorps, des vecteurs comprenant ces acides nucléiques, et des cellules hôtes transformées avec ces vecteurs. L'invention concerne en outre des compositions pharmaceutiques comprenant ces anticorps. L'invention concerne des méthodes permettant de traiter un patient atteint d'un cancer et permettant d'inhiber la phosphorylation du récepteur du facteur de croissance insulinomimétique de type I. L'invention concerne également des méthodes permettant de diagnostiquer un cancer.
