Findings from People with Acute Myeloid Leukemia Point to a New Understanding of Drug Resistance
Drug resistance is a formidable challenge in cancer treatment. A drug called enasidenib (Idhifa®) was approved by the US Food and Drug Administration last year for the treatment of people with a form of acute myeloid leukemia (AML) that’s driven by a mutation in the gene IDH2. About 15 percent of people with AML have this mutation. Research led by Memorial Sloan Kettering Cancer Center (MSK) reports that people who take enasidenib can develop resistance to it — in a way never seen before. Enasidenib works differently than most cancer drugs. Rather than killing leukemia cells, it turns them into normal blood cells. The discovery of this unique resistence may lead to more-precise treatments for people with AML in the future.
