CPX-351 plus gemtuzumab ozogamicin for relapsed/refractory acute myelogenous leukemia: a University of California Hematologic Malignancies Consortium trial.
In this multicenter phase Ib trial, we investigated the combination of CPX-351 and gemtuzumab ozogamicin (GO) in relapsed/refractory acute myeloid leukemia (AML). Cohort A received CPX-351 plus a single dose of GO, while cohort B received two doses of GO. Thirteen participants received investigational treatment. Dose-limiting toxicities (DLTs) occurred in one participant in each cohort, with manageable adverse events. No cases of hepatic sinusoidal obstructive syndrome occurred. Out of 12 evaluable participants, four achieved complete remission (CR), three of whom were negative for measurable residual disease. The median time to recovery of hematopoiesis for responders was 37 days. CPX-351 with GO was feasible with acceptable toxicity and marrow recovery kinetics. Further evaluation in a larger patient cohort is necessary to assess the efficacy of this regimen in relapsed/refractory AML.
期刊介绍：
Leukemia & Lymphoma in its fourth decade continues to provide an international forum for publication of high quality clinical, translational, and basic science research, and original observations relating to all aspects of hematological malignancies. The scope ranges from clinical and clinico-pathological investigations to fundamental research in disease biology, mechanisms of action of novel agents, development of combination chemotherapy, pharmacology and pharmacogenomics as well as ethics and epidemiology. Submissions of unique clinical observations or confirmatory studies are considered and published as Letters to the Editor
