The European Commission has approved dasatinib (Sprycel) for use in combination with chemotherapy for the treatment of pediatric patients with newly diagnosed, Philadelphia chromosome–positive (Ph+) acute lymphoblastic leukemia (ALL).
Dasatinib will be available in tablet form and as a powder for oral suspension, Bristol-Myers Squib said in a press release.
The approval was based on an event-free survival rate of 65.5% (95% confidence interval, 57.7-73.7) and an overall survival rate of 91.5% (95% CI, 84.2-95.5) in a phase 2 trial that evaluated the addition of dasatinib to a chemotherapy regimen modeled on a Berlin-Frankfurt-Münster high-risk backbone in pediatric patients with newly diagnosed Ph+ ALL.
Patients treated in the study (n = 106) were all aged younger than 18 years and received dasatinib at a daily dose of 60 mg/m2 on a continuous dosing regimen for up to 24 months, in combination with chemotherapy. About 77 % of patients (n = 82) received tablets exclusively; 23% of patients (n = 24) received the powder for oral suspension at least once.
Hematologic adverse events included grade 3 or 4 febrile neutropenia (75.5%), sepsis (23.6%), and bacteremia (24.5%). Nonhematologic, noninfectious grade 3 or 4 adverse events attributed to dasatinib and reported in more than 10% of patients included elevated ALT (21.7%) and AST (10.4%). Additional grade 3 or 4 adverse events attributed to dasatinib were pleural effusion (3.8%), edema (2.8%), hemorrhage (5.7%), and cardiac failure (0.8%). No events of pulmonary hypertension or pulmonary arterial hypertension were reported, the company said in the press release.
Dasatinib is already approved by the European Commission to treat children with Ph+ chronic myeloid leukemia in the chronic phase, which includes newly diagnosed patients and those with resistance or intolerance to imatinib.
