Drug confers benefits for subset of AML patients

For many of the most common adverse events, there were minimal differences between the treatment arms. These events included febrile neutropenia, infection, rash, diarrhea, nausea, edema, and constipation.

Patients in the CPX-351 arm had a higher incidence of grade 3-4 infection than controls—70.6% and 43.9%, respectively—but not infection-related deaths—3.5% and 7.3%, respectively.

The median time to neutrophil recovery (to ≥ 1000/μL) was longer in the CPX-351 arm than the control arm—36 days and 32 days, respectively. The same was true for platelet recovery (to ≥ 100,000/μL)—37 days and 28 days, respectively.

Researchers are now conducting a phase 3 trial of CPX-351, which is open and recruiting patients.
