SOUTH SAN FRANCISCO, Calif., June 20, 2012 /PRNewswire/ -- Onyx Pharmaceuticals, Inc. (Nasdaq: ONXX) today announced that the U.S. Food and Drug Administration's (FDA) Oncologic Drugs Advisory Committee (ODAC) determined by a vote of 11-0 [with 1 abstention] that, in 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 benefit-risk assessment is favorable for the use of Kyprolis™ (proposed brand name for carfilzomib). Onyx is developing Kyprolis for use in multiple myeloma across a variety of treatment lines. "Today's ODAC recommendation is an important regulatory milestone in the review of Kyprolis for relapsed and refractory multiple myeloma," said Ted W. Love, M.D., Executive Vice President, Research and Development and Technical Operations at Onyx Pharmaceuticals. "Onyx is committed to bringing Kyprolis to patients as quickly as possible and looks forward to working closely with the FDA as the agency completes its review." The Prescription Drug User Fee Act (PDUFA) date for completion of FDA review of the Kyprolis NDA for accelerated approval is July 27, 2012. The ODAC provides FDA with independent expert advice and recommendations, however the final decision regarding approval is made by FDA.

The 003-A1 trial evaluated 266 heavily-pretreated patients with relapsed and refractory multiple myeloma who had received at least two prior therapies, including bortezomib and either thalidomide or lenalidomide.
