Clofarabine. Bioenvision/ILEX.

Clofarabine is a purine nucleoside antimetabolite under development by Bioenvision (under license from the Southern Research Institute) and ILEX for the potential treatment of solid tumors, acute myelogenous leukemia, non-Hodgkin's lymphoma, and acute lymphoblastic and chronic lymphocytic leukemia. In September 2003, Bioenvision initiated a phase II trial in Europe in pediatric acute lymphoblastic leukemia, and in October 2003, ILEX submitted the first part of a rolling NDA to the FDA for the treatment of acute leukemia in children.
