SAN FRANCISCO, Dec. 7 /PRNewswire-FirstCall/ -- Sunesis Pharmaceuticals, Inc. (Nasdaq: SNSS) today announced the presentation of new data from two ongoing clinical trials demonstrating that the company's novel drug candidate, voreloxin, shows promising safety and efficacy results both in patients with newly diagnosed and relapsed/refractory acute myeloid leukemia (AML). These data were presented today at two poster sessions at the 50th Annual Meeting of the American Society of Hematology in San Francisco. The presentations are highlighted below.

Phase 2 Study of Voreloxin as Single Agent Therapy (REVEAL-1 Trial)

Interim data from the REVEAL-1 (Response Evaluation of VorEloxin in AmL) single agent Phase 2 trial show that voreloxin induces complete remissions in poor risk frontline elderly AML patients who are unlikely to benefit from standard induction chemotherapy. Many older AML patients cannot tolerate or do not respond well to standard induction chemotherapy. In Schedule A, 29 patients with a median age of 75 were enrolled and treated with 72 mg/m(2) of voreloxin weekly for three weeks. Eleven patients achieved a complete remission (CR) or complete remission without full platelet recovery (CRp) for an overall remission rate of 38 percent. An additional 5 patients had bone marrow blast reductions to less than 5 percent. The median duration of response for patients achieving a CR or CRp has not been reached.
