The European Commission (EC) has approved CPX-351 (Vyxeos), a liposomal formulation that delivers a fixed ratio of daunorubicin and cytarabine (44 mg/100 mg).
CPX-351 is approved to treat adults with newly diagnosed, therapy-related acute myeloid leukemia (AML) or AML with myelodysplasia-related changes.
The approval extends to all European Union member states as well as Iceland, Norway, and Liechtenstein.
The EC’s approval is supported by data from 5 studies, including a phase 3 trial.
Data from the phase 3 trial were published in the Journal of Clinical Oncology in July.
The trial enrolled 309 patients, ages 60 to 75, with newly diagnosed, therapy-related AML or AML with myelodysplasia-related changes.
Patients received CPX-351 (n=153) or cytarabine and daunorubicin (7+3; n=156).
The overall remission rate—the rate of complete response (CR) plus CR with incomplete count recovery—was 47.7% in the CPX-351 arm and 33.3% in the 7+3 arm (P=0.016). The CR rate was 37.3% and 25.6%, respectively (P=0.040).
About 30% of patients went on to allogeneic hematopoietic stem cell transplant—34% in the CPX-351 arm and 25% in the 7+3 arm (P=0.098).
The median overall survival was 9.56 months in the CPX-351 arm and 5.95 months in the 7+3 arm (P=0.003). The median event-free survival was 2.53 months and 1.31 months, respectively (P=0.021).
Adverse events (AEs) that led to treatment discontinuation in the CPX-351 arm were cardiac failure (n=1), cardiomyopathy (n=1), and acute renal failure (n=1). AEs that led to treatment discontinuation in the 7+3 arm were decreased ejection fraction in 2 patients.
The most common grade 3 to 5 AEs (in the CPX-351 and 7+3 arms, respectively) were infection-related events (83.7% and 86.1%), febrile neutropenia (68.0% and 70.9%), pneumonia (19.6% and 14.6%), hypoxia (13.1% and 15.2%), and bleeding events (11.8% and 8.6%).
Ultimately, 69.3% of patients in the CPX-351 arm and 84.8% of those in the 7+3 arm died.
Deaths (in the CPX-351 and 7+3 cohorts, respectively) were due to progressive disease (n=65 and 67), AEs (n=15 and 19), cancer-related organ failure in the absence of progressive disease (n=0 and 5), and unknown/other causes (n=26 and 37).
