A Study Evaluating the Safety and Pharmacology of Atezolizumab Administered in Combination With Immunomodulatory Agents in Participants With Acute Myeloid Leukemia (AML)

Completed · Phase 1

Conditions studied: Acute Myeloid Leukemia

In brief

This is a non-randomized, open-label, Phase Ib study of atezolizumab in combination with immunomodulatory agents for the treatment of participants with AML (relapsed/refractory and treatment-naive, elderly participants unfit for induction chemotherapy). The study has been designed with the intent, over time, to study multiple combinations of atezolizumab with different immunomodulatory agents in participants with AML. The study will begin with the evaluation of the combination of atezolizumab and guadecitabine (Arm A). In the future, additional arms may be added.

• For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive methods that result in a failure rate of less than (<) 1 percent (%) per year during the treatment period and for at least 30 days after the last dose of guadecitabine or 5 months after the last dose of atezolizumab, whichever is longer
• For men: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive measures, and agreement to refrain from donating sperm
