Run by M.D. Anderson Cancer Center · NCT03896269 · Data updated 2026-11-12

This study is testing a new treatment called CPX-351 to see if it can safely help people with high-risk blood cancers like myelodysplastic syndrome or chronic myelomonocytic leukemia.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include patients diagnosed with intermediate-2 or high-risk MDS or CMML who have not responded to previous therapies and are not eligible for stem cell transplant.

Probably not a fit

Patients with low-risk MDS or CMML or those who have not exhausted other treatment options may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This phase I trial investigates the safety, tolerability, and efficacy of liposome-encapsulated daunorubicin-cytarabine (CPX-351) in patients with relapsed or refractory high-risk myelodysplastic syndrome (MDS) or chronic myelomonocytic leukemia (CMML). The study involves a dose-escalation approach to determine the maximum tolerated dose and assess the overall response rate, survival, and safety profile of the treatment. Patients will receive the drug intravenously over specified days, with follow-up assessments to evaluate treatment outcomes.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with high-risk MDS or CMML who have limited treatment alternatives.

How similar studies have gone: Other studies have shown promise with similar chemotherapy approaches, but this specific combination is being evaluated for the first time in this patient population.
