Trial Outcomes & Findings for CPX-351 Therapy for MDS After Hypomethylating Agent Failure (NCT NCT03957876)

NCT ID: NCT03957876

Last Updated: 2024-08-15

Results Overview

Efficacy of CPX as measured by ORR as defined by IWG 2006 criteria for MDS participants at end of induction. IWG 2006 responses that must be for at least 4 weeks include Complete Remission (CR), Partial Remission (PR), Marrow CR, Stable Disease (SD), Failure, Relapse after CR or PR (PD), or cytogenetic response. Hematologic Improvement (HI), which must be for at least 8 weeks, includes erythroid response (pretreatment, \< 11 g/dL), Platelet response (pretreatment, \< 100x109/L), Neutrophil response (pretreatment, \< 1 x109/L), or Progression or relapse after HI.

Measure
Intravenous CPX-351 With Potential Maintenance Therapy
Single agent CPX-351 administered at the standard FDA approved dose of 44 mg/m2 intravenously on days 1, 3, 5 of the induction cycle. If participants achieve complete remission (CR), complete remission with incomplete count recovery (CRi) or partial remission (PR), they will be eligible to continue on to maintenance therapy, which will consist of CPX351 at a dose of 15.4 mg/m2 every 28 days. Participants can receive up to 4 cycles of maintenance therapy. CPX-351: CPX-351 is a liposomal formulation of a fixed combination of the antineoplastic drugs cytarabine and daunorubicin.
