Trial Outcomes & Findings for CPX-351 in Treating Patients With Newly Diagnosed, High-Risk Acute Myeloid Leukemia (NCT NCT02286726)

NCT ID: NCT02286726

Last Updated: 2026-03-04

Results Overview

Response is defined as Complete response (CR) or CR with incomplete blood count recovery (CRi) rate: Complete Remission (CR) is Bone marrow blasts \<5%; absence of blasts with Auer rods; absence of extramedullary disease; absolute neutrophil count \>1.0 x 10\^9/L (1000/μL); platelet count \>100 x 10\^9/L (100,000/μL). Complete Response with incomplete blood count recovery (CRi) is All CR criteria except for residual neutropenia (\<1.0 x 10\^9/L \[1000/μL\]) and/or thrombocytopenia (\<100 x 10\^9/L \[100,000/μL\]).

SECONDARY outcome

Timeframe: Up to day 60

Defined as induction mortality (death occurring on or before day 60), grade 3 or 4 non-hematologic toxicity, or dose limiting hematologic toxicity at least possibly related to the study drug occurring during the first 28 days from the start of therapy. Estimated for each arm with 95% confidence intervals. Fisher's exact test will be used to compare the toxicity rate between the two dose levels.
