The US Food and Drug Administration (FDA) granted Priority Review to duvelisib for patients with chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL) or follicular lymphoma, according to a press release.1 The drug’s manufacturer is seeking full approval for relapsed/refractory CLL/SLL and accelerated approval for relapsed/refractory follicular lymphoma.

Duvelisib, a first-in-class dual inhibitor of PI3K-delta and -gamma, was evaluated in patients with relapsed/refractory CLL/SLL in the randomized phase 3 DUO trial (ClinicalTrials.gov Identifier: NCT02004522) and in patients with refractory indolent non-Hodgkin lymphoma in the single-arm phase 2 DYNAMO trial (ClinicalTrials.gov Identifier: NCT01882803). The primary endpoints of both studies were met.

The FDA is reviewing a New Drug Application, which is requesting full approval for CLL/SLL and accelerated approval for follicular lymphoma. The target action date is October 5, 2018.
