Phase 1 Study of Selinexor in Combination With Topoisomerase-II Inhibition in Acute Myeloid Leukemia

OSU 14089

This phase I trial studies the side effects and best dose of selinexor when given together with etoposide with or without mitoxantrone hydrochloride and cytarabine in treating patients with acute myeloid leukemia that has returned (relapsed) or has not responded to treatment (refractory). Selinexor may help stop the growth of tumor cells by blocking an enzyme needed for cancer cell growth. Drugs used in chemotherapy, such as etoposide, mitoxantrone hydrochloride, and cytarabine, 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 chemotherapy together with selinexor work better in treating relapsed or refractory acute myeloid leukemia.
