A Phase 1/2 Study of Vorinostat (Zolinza®) in Combination With Gemtuzumab Ozogamicin (Mylotarg®) and Azacitidine (Vidaza®) in Patients 50 Years of Age and Older With Relapsed/Refractory Non-APL Acute Myeloid Leukemia (AML)

The purpose of this study is to test the safety of vorinostat (Zolinza) and azacitidine (Vidaza) when combined with gemtuzumab ozogamicin (GO) at different dose levels. These drugs increase the effect of GO against leukemia cells in the test tube, but we don't know yet whether they also increase the anti-leukemia effect of GO in people.
