A Study of RO5503781 as a Single Agent or in Combination With Cytarabine in Participants With Acute Myelogenous Leukemia

24 januari 2017 bijgewerkt door: Hoffmann-La Roche

A Multi-Center, Open-Label, Phase 1/1b Study of Escalating Doses of RO5503781 Administered Orally as 1) a Single Agent, 2) In Combination With Cytarabine, or 3) With Cytarabine and Anthracycline and 4) Assessing PK and Safety of New Optimized Formulation of RO5503781 With Cytarabine in Patients With Acute Myelogenous Leukemia (AML)

This Phase 1/1b, open-label study will evaluate the safety and pharmacokinetics of escalating doses of RO5503781 as a single agent or in combination with cytarabine in participants with acute myelogenous leukemia. In Part 1, RO5503781 will be administered in escalating doses as a single agent, and in Part 2, RO5503781 will be administered in combination with cytarabine. An optional Part 3 in which RO5503781 will be administered with cytarabine and anthracycline may be considered . In Part 4, the safety and pharmacokinetic profile of an optimized formulation of RO5503781 in combination with cytarabine will be assessed.
