October 12, 2009 updated by: Astex Pharmaceuticals, Inc.

A Phase II, Multicenter Study of Decitabine (5-aza-2'Deoxycytidine) in Chronic Myelogenous Leukemia Chronic Phase Refractory to Imatinib Mesylate (STI 571)

To determine the safety and efficacy of decitabine in patients with Philadelphia chromosome-positive chronic myelogenous leukemia chronic phase that were previously treated with imatinib mesylate (STI 571) and became resistant/refractory or were found to be intolerant to the drug.
