NORTH HOLLYWOOD, Calif.--(BUSINESS WIRE)--The International Myeloma Foundation (IMF), the oldest and largest foundation dedicated to improving the life and care of myeloma patients, today said promising data suggest a new drug called carfilzomib could become an important new option for patients whose myeloma stops responding to other therapies. Carfilzomib, from Onyx Pharmaceuticals, is a next-generation proteasome inhibitor that disrupts the life cycle of a cancer cell, and carfilzomib has shown favorable tolerability. Based on this Phase II clinical trial, Onyx could seek accelerated drug approval from the FDA by the end of 2010.
