Decitabine Followed by Mitoxantrone Hydrochloride, Etoposide, and Cytarabine in Treating Patients With Relapsed or Refractory Acute Myeloid Leukemia or High-Risk Myelodysplastic Syndromes

Mitoxantrone, Etoposide, and Cytarabine (MEC) Following Epigenetic Priming With Decitabine in Adults With Relapsed/Refractory Acute Myeloid Leukemia (AML) or High-Risk Myelodysplastic Syndromes (MDS): A Phase 1/2 Study

Summary

This phase I/II trial studies the side effects and best dose of decitabine followed by mitoxantrone hydrochloride, etoposide, and cytarabine and to see how well they work in treating patients with acute myeloid leukemia or high-risk myelodysplastic syndrome that has returned after a period of improvement or does not respond to treatment. Drugs used in chemotherapy, such as mitoxantrone hydrochloride, etoposide, cytarabine, and decitabine, 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 more than one drug (combination chemotherapy) may kill more cancer cells.

Detailed description

PRIMARY OBJECTIVES: I. Estimate the maximum tolerated dose (MTD) of decitabine priming followed by sequential mitoxantrone hydrochloride/etoposide/cytarabine (MEC) chemotherapy in adults with relapsed/refractory acute myeloid leukemia (AML). SECONDARY OBJECTIVES: I. Determine, within the limits of a Phase 1/2 study, disease response and duration of remission. II. Identify biomarkers (e.g., deoxyribonucleic acid \[DNA\] methylation and/or gene expression changes) associated with treatment responses. OUTLINE: This is a phase I, dose-escalation study of decitabine followed by a phase II study. Patients receive decitabine intravenously (IV) on days -9 to -5 (dose level 1), days -11 to -5 (dose level 2), or days -14 to -5 (dose level 3). INDUCTION THERAPY: Patients receive mitoxantrone hydrochloride IV on days 1-5, etoposide IV on days 1-5, and cytarabine IV on days 1-5. Patients achieving complete response (CR) or CR with incomplete platelet count recovery (CRp) may receive up to 2 courses of induction therapy and up to 2 courses of consolidation therapy. After completion of study treatment, patients are followed up every 3 months for up to 5 years.
