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.

Experimental: Treatment (liposome-encapsulated daunorubicin-cytarabine)
INDUCTION THERAPY: Patients receive liposome-encapsulated daunorubicin-cytarabine 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 CR/CRi/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 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. |
Drug: Liposome-encapsulated Daunorubicin-Cytarabine

Other Names:

- Incidence of adverse events (dose-escalation stage) [ Time Frame: Up to 30 days ]Safety data of the patients will be summarized using descriptive statistics such as mean, standard deviation, median, and range. Toxicity type, severity, and attribution will be summarized for each patient using frequency tables.
- Maximum-tolerated dose (MTD) of liposome-encapsulated daunorubicin-cytarabine (dose-escalation stage) [ Time Frame: Up to 28 days ]Defined as the highest dose level in which a dose-limiting toxicity (DLT) occurs within at most 1 out of 6 patients treated. DLTs are defined as any related non-hematological Common Terminology Criteria for Adverse Events grade >= 3 adverse events that prevent further administration of the agent at that same dose level.
- Incidence of adverse events (dose-expansion stage) [ Time Frame: Up to 30 days ]Safety data of the patients will be summarized using descriptive statistics such as mean, standard deviation, median, and range. Toxicity type, severity, and attribution will be summarized for each patient using frequency tables.
- Objective response rate (ORR) (dose-expansion stage) [ Time Frame: Up to 1.5 years ]Defined as complete response (CR), partial response, CR with incomplete bone marrow recovery, marrow CR or hematological improvement. Will be estimated along with 95% confidence intervals treated at the MTD (i.e., including those treated at the MTD during dose escalation and dose expansion phases). The association between ORR and patient's clinical characteristics will be examined by Wilcoxon's rank sum test or Fisher's exact test, as appropriate.
- Overall response rate [ Time Frame: Up to 1.5 years ]
- Overall survival [ Time Frame: Up to 1.5 years ]The distribution of time-to-event endpoints will be estimated using the method of Kaplan and Meier. Comparisons of time-to-event endpoints by important subgroups will be made using the log-rank tests.
- Duration of response [ Time Frame: Up to 1.5 years ]Will be summarized using descriptive statistics such as mean, standard deviation, median and range.
- Relapse-free survival [ Time Frame: Up to 1.5 years ]The distribution of time-to-event endpoints will be estimated using the method of Kaplan and Meier. Comparisons of time-to-event endpoints by important subgroups will be made using the log-rank tests.
- Incidence of adverse events [ Time Frame: Up to 1.5 years ]Safety data of the patients will be summarized using descriptive statistics such as mean, standard deviation, median, and range. Toxicity type, severity, and attribution will be summarized for each patient using frequency tables.
