Description

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.
