FDA has approved Copiktra (duvelisib), an oral inhibitor of phosphoinositide 3-kinase and the first approved dual inhibitor of PI3K-delta and PI3K-gamma. Copiktra is approved for the treatment of adult patients with relapsed or refractory chronic lymphocytic leukemia/small lymphocytic lymphoma after at least two prior therapies.
The agent is sponsored by Verastem Inc.
Copiktra also received accelerated approval for the treatment of adult patients with relapsed or refractory follicular lymphoma after at least two prior systemic therapies. The indication in FL is approved under accelerated approval based on overall response rate. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials.
Use of Copiktra is associated with a boxed warning for four fatal and/or serious toxicities: infections, diarrhea or colitis, cutaneous reactions, and pneumonitis. Verastem Oncology is implementing an informational Risk Evaluation and Mitigation Strategy to provide appropriate dosing and safety information to better support physicians in managing their patients on Copiktra.
Additionally, use of Copiktra is also associated with adverse reactions which may require dose reduction, treatment delay or discontinuation of Copiktra. Warnings and precautions are provided for infections, diarrhea or colitis, cutaneous reactions, pneumonitis, hepatotoxicity, neutropenia, and embryo-fetal toxicity.
