Original description

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.Read full original descriptionShow less

Phase 1 Dose Escalation Study of CPX-351 for Patients With Int-2 or High Risk IPSS Myelodysplastic Syndromes and Chronic Myelomonocytic Leukemia After Failure to Hypomethylating Agents

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.
