Leukemia, Myeloid, Acute
Conditions
Brief summary
The primary objective for this study is to assess the safety and tolerability as well as preliminary efficacy of venetoclax in combination with cobimetinib, and venetoclax in combination with idasanutlin in patients with relapsed or refractory acute myeloid leukemia (R/R) AML who are not eligible for cytotoxic therapy.
Interventions
Cobimetinib will be administered orally as per schedule in Arm description.
Idasanutlin will be administered orally as per schedule in Arm description.
Venetoclax will be administered orally as per schedule in Arm description.

Eligibility
Inclusion criteria
