Bayer Gets Priority Review for Lymphoma Therapy
FDA has granted Bayer a priority review on its NDA for copanlisib for treating relapsed or refractory follicular lymphoma (FL) patients who have received at least two prior therapies. Copanlisib is an intravenous pan-class I phosphatidylinositol-3-kinase (PI3K) inhibitor that the company says has “predominant inhibitory activity against PI3K-α and PI3K-δ isoforms.
The submission is based on data from the Phase 2 open-label, single-arm study CHRONOS-1 involving 141 indolent Non-Hodgkin’s Lymphoma (iNHL) patients. “At the time of analysis, median duration of treatment was 22 weeks and 46 patients remained on treatment,” the company says. “The results across all patient groups show an objective response rate (ORR) of 59.2%, with a 12% complete response (CR) rate, and a median duration of response (DOR) of more than 98 weeks (687 days). In the FL subset (n=104), copanlisib achieved an ORR of 58.7%, with 14.4% of these patients achieving a CR, and a median DOR of more than 52 weeks (370 days).”
