Myelodysplastic Syndrome Clinical Trial

CPX-351 in Treating Patients With Relapsed or Refractory High Risk Myelodysplastic Syndrome or Chronic Myelomonocytic Leukemia

Summary

This phase I trial studies best dose and side effects of liposome-encapsulated daunorubicin-cytarabine (CPX-351) and how well it works in treating patients with high risk myelodysplastic syndrome or chronic myelomonocytic leukemia that has come back or has not responded to treatment. Drugs used in chemotherapy, such as liposome-encapsulated daunorubicin-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.

PRIMARY OBJECTIVES:

I. To characterize the safety and tolerability of CPX-351 in patients with intermediate-2 or high-risk myelodysplastic syndrome (MDS). (Dose Escalation Stage) II. To determine the maximum tolerated dose (MTD) of intravenous CPX-351 in patients with intermediate-2 or high-risk MDS. (Dose Escalation Stage) III. To further characterize the safety and tolerability of CPX-351 in patients with intermediate-2 and high-risk MDS. (Dose-Expansion Stage) IV. To evaluate preliminary efficacy of CPX-351 in patients with intermediate-2 or high-risk MDS. (Dose-Expansion Stage)

SECONDARY OBJECTIVES:

I. To assess overall response (OR) rate. II. To assess overall survival. III. To assess duration of response. IV. To assess relapse-free survival. V. To assess safety profile.

OUTLINE: This is a dose-escalation study.

INDUCTION THERAPY: Patients receive liposome-encapsulated daunorubicin-cytarabine intravenously (IV) over 90 minutes on days 1, 3, and 5 in the absence of disease progression or unacceptable toxicity. After 2-5 weeks, patients who do not achieve a complete response (CR)/CR with incomplete bone marrow recovery (CRi)/CR with incomplete platelet recovery (CRp), have acceptable or no toxicity, and have stable disease and no disease progression may receive liposome-encapsulated daunorubicin-cytarabine IV over 90 minutes on days 1 and 3 in the absence of disease progression or unacceptable toxicity.

CONSOLIDATION THERAPY: Patients who achieve at least a hematological improvement (HI) response, receive liposome-encapsulated daunorubicin-cytarabine IV over 90 minutes on days 1 and 3. Treatment repeats every 28 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity. After 5-8 weeks, patients who do not show clinically significant disease progression or unacceptable toxicity may receive liposome-encapsulated daunorubicin-cytarabine for up to 12 additional cycles.

After completion of study treatment, patients are followed up at 30 days and then every 6 months thereafter.
