Azacitidine and Enasidenib in Treating Patients With IDH2-Mutant Myelodysplastic Syndrome
Trial Parameters
Brief Summary
This phase II trial studies the side effects and how well azacitidine and enasidenib work in treating patients with IDH2-mutant myelodysplastic syndrome. Azacitidine and enasidenib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
