The US Food and Drug Administration (FDA) has accepted for priority review a supplemental new drug application (sNDA) for dasatinib (Sprycel).
Bristol Myers Squibb is seeking approval for dasatinib as a treatment for children with Philadelphia chromosome-positive (Ph+) chronic phase (CP) chronic myeloid leukemia (CML), as well as approval for a powder formulation of dasatinib for oral suspension.
The FDA grants priority review to applications for products that may provide significant improvements in the treatment, diagnosis, or prevention of serious conditions.
The agency’s goal is to take action on a priority review application within 6 months of receiving it, rather than the standard 10 months.
The FDA plans to make a decision on the dasatinib sNDA by November 9, 2017.
The sNDA includes data from CA180-226 (NCT00777036), an ongoing, phase 2 trial of dasatinib in pediatric patients with CP-CML who are resistant to or cannot tolerate imatinib and pediatric patients newly diagnosed with CP-CML.
The trial enrolled patients aged 18 and younger with newly diagnosed CML or Ph+ leukemias resistant to or intolerant of imatinib.
Cohort 1 included 29 CP-CML patients resistant to or intolerant of imatinib. Cohort 2 included patients with accelerated/blast phase CML or Ph+ acute lymphoblastic leukemia. Cohort 3 included 84 patients with newly diagnosed CP-CML.
Data from Cohorts 1 and 3 were recently presented at the 2017 ASCO Annual Meeting.
Three months into treatment with dasatinib, patients with CP-CML who were resistant to or intolerant of imatinib (Cohort 1) had a cumulative major cytogenetic response rate of 55.2%. This response rate increased over time to exceed 90% at 24 months.
Newly diagnosed patients with CP-CML (Cohort 3) received dasatinib orally or as powder for oral suspension once daily. They achieved a cumulative complete cytogenetic response rate of 64% as early as 6 months into treatment. This response rate increased to 94% at 24 months.
The median duration of response was not estimable or not yet reached in each cohort at the time of follow-up.
The estimated progression-free survival at 48 months was greater than 75% for patients in Cohort 1 and greater than 90% for patients in Cohort 3.
The safety profile of dasatinib in this study was deemed comparable to that reported in adults with CP-CML. In this study, there were no reported events of pleural/pericardial effusion, pulmonary edema/hypertension, or pulmonary arterial hypertension related to dasatinib.
Dasatinib first received FDA approval in 2006. The drug is currently approved to treat adults with:
- Newly diagnosed Ph+ CP-CML
- Chronic, accelerated, or blast phase Ph+ CML with resistance or intolerance to prior therapy including imatinib
- Ph+ acute lymphoblastic leukemia with resistance or intolerance to prior therapy.
