Duvelisib is a first-in-class oral dual inhibitor of phosphoinositide 3-kinase (PI3K)-delta and PI3K-gamma, for which Verastem is seeking full approval for the treatment of relapsed or refractory chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) and accelerated approval for the treatment of relapsed or refractory follicular lymphoma (FL). The FDA target action date is October 5, 2018.
Verastem president and CEO Robert Forrester said: “Obtaining Priority Review in the U.S. for duvelisib marks another important milestone for Verastem and speaks to the unmet need in relapsed/refractory CLL/SLL and FL and the urgency to identify effective therapies to treat these patients.
“As an orally administered therapy, we believe duvelisib will provide an important treatment option for patients with CLL/SLL and FL, and for the physicians who treat them. We look forward to working with the FDA during the review process.
“We are continuing our commercial preparations for duvelisib to execute the launch promptly in the U.S. if approved. In parallel, we are exploring ex-U.S. partnering opportunities for duvelisib and plan to file a European Marketing Application towards the end of the year.”
Priority Review is granted by the FDA to drugs that, if approved, would provide significant improvements in the safety or effectiveness of the treatment, diagnosis, or prevention of a serious condition.
Duvelisib has received Fast Track Designation from the FDA for patients with CLL who have received at least one prior therapy and for patients with FL who have received at least two prior therapies.
In addition, duvelisib received orphan drug designation in the United States and the European Union for patients with CLL, SLL and FL.
