Ivosidenib and Venetoclax With or Without Azacitidine in Treating Patients With IDH1 Mutated Hematologic Malignancies

Is NCT03471260 recruiting? Yes, currently enrolling (May 2026). This Phase 1/2 trial studies multiple treatments including Azacitidine and Ivosidenib for acute myeloid leukemia.

Phase 1/2RecruitingM.D. Anderson Cancer CenterNCT03471260Data as of May 2026

Treatment: Azacitidine · Ivosidenib · VenetoclaxThis phase Ib/II trial studies the side effects and best dose of venetoclax and how well it works when given together with ivosidenib with or without azacitidine, in treating patients with IDH1-mutated hematologic malignancies. Venetoclax and ivosidenib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as azacitidine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving ivosidenib and venetoclax with azacitidine may work better in treating patients with hematologic malignancies compared to ivosidenib and venetoclax alone.
