Study of Enasidenib and Venetoclax in IDH2-Mutated Blood Cancers

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.

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.
