the European Medicines Agency (EMA) on the design and planned analysis of the ASPIRE trial."The ASPIRE trial, which is designed to support full approval of carfilzomib for patients with relapsed multiple myeloma, is an important component of our overall regulatory strategy to bring carfilzomib to the broadest number of patients in need of new treatment options," said Ted W. Love, M.D., Executive Vice President and Head of Research and Development and Technical Operations at Onyx Pharmaceuticals. "We are pleased to have completed enrollment in the ASPIRE study ahead of schedule, and could have interim results as early as the first half of 2013."The FDA is currently reviewing a New Drug Application (NDA) for potential accelerated approval of carfilzomib in the U.S. for the treatment of patients with relapsed and refractory multiple myeloma. The Prescription Drug User Fee Act (PDUFA) date for completion of the NDA review by the FDA is July 27, 2012.Phase 3 Trial DesignThe ASPIRE (CArfilzomib, Lenalidomide, and DexamethaSone versus Lenalidomide and Dexamethasone for the treatment of PatIents with Relapsed Multiple MyEloma) trial is evaluating carfilzomib in combination with lenalidomide and low-dose dexamethasone, versus lenalidomide and low dose dexamethasone alone, in patients with relapsed multiple myeloma following treatment with one to three prior regimens. The primary endpoint of the trial is progression-free survival. Secondary endpoints include overall survival, overall response rate, duration of response, disease control rate, safety, time-to-progression and time-to-next treatment. Patients were randomized to receive carfilzomib (20mg/m2 on days 1 and 2 of cycle 1 only, then 27mg/m2 subsequently), in addition to a standard dosing schedule of lenalidomide (25mg per day for 21 days on, 7 days off) and low-dose dexamethasone (40mg per week in 4 week cycles), versus lenalidomide and low-dose dexamethasone alone.The study targeted enrollment of 780 patients and is being conducted at approximately 200 sites in North America, Europe, and Israel.

Phase 1/2 Study ResultsAs previously reported at the 47thAmerican Society of Clinical Oncology (ASCO) Annual Meeting, a Phase 1/2 dose-escalation trial, known as the 006 study, evaluated carfilzomib in combination with lenalidomide and low dose dexamethasone in patients with relapsed and/or refractory myeloma. The overall response rate in the cohorts of patients receiving full doses of the combination was 78 percent in 51 evaluable patients. The combination was well tolerated and demonstrated activity, including in patients who had received prior bortezomib treatment and an immunomodulatory drug (IMiD). No dose-limiting toxicities were observed, and the maximum tolerated dose was not reached. The maximum per-protocol doses of 27mg/m2 carfilzomib, 25mg lenalidomide, and low dose (40mg) dexamethasone were administered. The most common Grade 3/4 adverse events included neutropenia (23%), thrombocytopenia (15%), anemia (15%), hypophosphatemia (13%), fatigue (12%), hyperglycemia (8%), lymphopenia (8%), hyponatremia (6%), diarrhea (6%) and pneumonia (6%). Hematologic adverse events were reversible and manageable.
