Onyx commences ENDEAVOR Kyprolis Phase 3 trial for relapsed multiple myeloma

Onyx Pharmaceuticals, Inc. (Nasdaq: ONXX) announced today that the company has begun enrollment in the ENDEAVOR trial, a Phase 3 trial evaluating Kyprolis™ (proposed brand name for carfilzomib) in combination with dexamethasone, versus bortezomib (Velcade®) with dexamethasone in patients with relapsed multiple myeloma.

"The ENDEAVOR trial is the first head-to-head trial conducted with Kyprolis, and is an important step in the development program," said Ted W. Love, M.D., Executive Vice President, Research and Development and Technical Operations at Onyx Pharmaceuticals. "The initiation of this trial underscores our commitment to patients with multiple myeloma who are in need of new treatment options beyond the currently available therapies."

The FDA is currently reviewing a New Drug Application (NDA) for potential accelerated approval of Kyprolis in the U.S. for the treatment of patients with relapsed and refractory multiple myeloma who have received at least two prior lines of therapy that included a proteasome inhibitor and an immunomodulatory agent (IMiD). The Prescription Drug User Fee Act (PDUFA) date for completion of the NDA review by the FDA is July 27, 2012.
