|Condition or disease||Intervention/treatment||Phase|
|Acute Myeloid Leukemia Relapsed Cancer Refractory Cancer IDH2 Gene Mutation||Drug: Enasidenib Drug: Venetoclax||Phase 1 Phase 2|
This study will have two parts: Phase 1b and Phase 2. The part that patients may participate in will depend on when they join the study.
In the phase 1b portion of the study, small groups participants will receive increasing doses of venetoclax in combination with a flat dose of enadisenib until the highest dose or best dose of venetoclax that is safe and tolerable in combination with enadisenib is found.
In the phase 2 portion of the study, an additional group of participants will receive the highest or best dose of venetoclax found in the Phase 1b portion of the study with a flat dose of enadisenib to see how useful the combination is in treating relapsed or refractory acute myeloid leukemia (AML).

|Official Title:||Phase Ib/II Study of IDH2 Inhibitor Enasidenib in Combination With BCL2 Inhibitor Venetoclax in Patients With IDH2-Mutated Myeloid Malignancies (ENAVEN-AML)|
|Actual Study Start Date :||November 5, 2020|
|Estimated Primary Completion Date :||August 2023|
|Estimated Study Completion Date :||February 2024|
Experimental: Venetoclax and Enadisenib
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.
Enasidenib is a drug that blocks a protein called isocitrate dehydrogenase (IDH) 2 from working. The family of IDH proteins have been indicated in the development of leukemia. By blocking IDH2, enasidenib may help stop cancer cells from growing. It is believed that the drug may be more useful in patients with a change (mutation) in their IDH 2 protein. The IDH2 gene (substances in the body that contain instructions for the proper development and function of cells) makes IDH2 proteins. As such, only patients with IDH 2 mutated gene are eligible for this study. Enasidenib is currently approved for the treatment of IDH2 mutated AML.
Other Name: IDHIFA
Venetoclax is a drug that blocks a protein called B-cell lymphoma (BCL2) protein from working. BCL2 is a protein that helps control whether a cell lives or dies and is thought to help cancer cells to live. Blocking BCL2 is believed to help kill cancer cells. Venetoclax is currently approved for the treatment of type of blood cancer called chronic lymphocytic leukemia (CLL) who have received prior treatment.
Other Name: VENCLEXTA
- Overall response rate (ORR) [ Time Frame: 3 years ]
- Dose Limiting Toxicity [ Time Frame: 28 days ]
- Maximum tolerated dose or Recommended Phase 2 Dose [ Time Frame: 3 years ]Dose indicated by the mTPI decision
