Dasatinib in children and adolescents with relapsed or refractory leukemia: results of the CA180-018 phase I dose-escalation study of the Innovative Therapies for Children with Cancer Consortium.
Abstract | PURPOSE: PATIENTS AND METHODS: RESULTS:
Dasatinib safety and efficacy profiles compared favorably with those in adults. The most common drug-related nonhematologic adverse events were nausea (31%, all grades; 2%, grade 3 to 4), headache (22%, 3%), diarrhea (21%, 0%), and vomiting (17%, 2%). Of 17 patients with CML- CP, 14 (82%) achieved complete cytogenetic response (CCyR) and eight (47%) achieved major molecular response. After ≥ 24 months of follow-up, median complete hematologic response (CHR) and major cytogenetic response (MCyR) durations were not reached. Of 17 patients with advanced-phase CML or Ph-positive ALL, six (35%) achieved confirmed CHR and 11 (65%) achieved CCyR. Median MCyR duration was 4.6 months (95% CI, 2.1 to 17.4 months). No patient with Ph-negative ALL or AML responded. Dasatinib pediatric pharmacokinetic parameters were comparable with those in adult studies, showing rapid absorption (time to reach maximum concentration, 0.5 to 6.0 hours) and elimination (mean half-life, 3.0 to 4.4 hours). CONCLUSION:
Dasatinib 60 mg/m(2) and 80 mg/m(2) once-daily dosing were selected for phase II studies in children with Ph-positive leukemias.
