The US Food and Drug Administration (FDA) agreed to a priority review of a supplemental New Drug Application (sNDA) for dasatinib, according to a press release.1 The application is for potential new indications of dasatinib for pediatric patients with Philadelphia chromosome–positive (Ph+) chronic phase chronic myeloid leukemia (CP-CML), as well as a powder for oral suspension formulation of dasatinib.1
Dasatinib, a tyrosine kinase inhibitor (TKI), is indicated for adult patients with newly diagnosed, Ph+ CML, adults with Ph+ CP CML resistant or intolerant to prior therapy, and adults with Ph+ acute lymphoblastic leukemia (ALL) with intolerance or resistance to prior therapy.

The FDA granted priority review to this sNDA based on data from the ongoing phase 2 trial CA180-226 (ClinicalTrials.gov Identification: NCT00777036). The study enrolled pediatric patients who were newly diagnosed with CP-CML, or patients with CP-CML resistant or intolerant to imatinib.
Study measures included cumulative complete cytogenetic response rate in newly diagnosed patients, cumulative major cytogenetic response rate among imatinib-resistant or -intolerant patients, time to and duration of response, major molecular response, overall survival, progression-free survival, and safety.
