Study of Enasidenib and Venetoclax in IDH2-Mutated Blood Cancers

Phase Ib/II Study of IDH2 Inhibitor Enasidenib in Combination With BCL2 Inhibitor Venetoclax in Patients With IDH2-Mutated Myeloid Malignancies (ENAVEN-AML)

Summary

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.

Detailed description

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).

Conditions

• Acute Myeloid Leukemia
• Relapsed Cancer
• Refractory Cancer
• IDH2 Gene Mutation

Interventions

Type	Name	Description
DRUG	Enasidenib	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.
DRUG	Venetoclax	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.
