Summary
Brief summary (as posted)
The purpose of this research study is to see how safe and tolerable, and to find the highest or best dose, of an investigational combination of drugs called enasidenib and venetoclax, in patients with relapsed (the cancer has come back) or refractory (the cancer does not respond or have stopped responding to treatment) acute myeloid leukemia (AML, a type of blood cancer). This study will also see how useful the combination of enasidenib and venetoclax is in the treatment of patients with relapsed or refractory AML.

- description
- Enasidenib and venetoclax will be taken by mouth (orally), once a day, every day, continuously. Every 28-day period will be called a cycle. Participants will start venetoclax alone on Cycle 1 Day 1 and continue the study drug alone until Day 15. On Day 15, participants will take enasidenib and venetoclax together and will continue to take the combination of study drugs until intolerable side effects or disease worsening.
