After a Secura Bio strategic assessment of COPIKTRA and subsequent consultation with the U.S. Food and Drug Administration (FDA), the company made the determination that the current treatment landscape for FL patients in the U.S. and the logistics, cost and timing of the post-marketing requirements (PMR) for COPIKTRA in FL was no longer merited. Secura Bio has determined that a more prudent application of future effort and resource is in new applications for T-cell lymphoma where initial data appear encouraging. The company is looking forward to working with the FDA and gaining guidance regarding an appropriate regulatory and clinical plan.

This is a business decision and is not related to any changes in either the efficacy or safety associated with COPIKTRA. This decision impacts only the relapsed or refractory FL indication in the U.S. and does not affect other approved indications for COPIKTRA in the U.S. and other countries, including the treatment of adult patients with relapsed or refractory chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) after at least two prior therapies.

Secura Bio will work with the FDA over the coming weeks to complete the label revision process, including notification of U.S. healthcare professionals in a timely manner about the label change. Patients in the U.S. being treated with COPIKTRA for relapsed or refractory FL should discuss their care with their healthcare provider. Patients, or their healthcare providers, who have questions or concerns are encouraged to contact Secura Bio at (805) 479-7793 for assistance. Secura Bio patient support specialists can help answer questions, including insurance coverage and reimbursement options.

About COPIKTRA (duvelisib)

COPIKTRA is an oral inhibitor of phosphoinositide 3-kinase (PI3K), and the first United States FDA approved dual inhibitor of PI3K-delta and PI3K-gamma, two enzymes known to help support the growth and survival of malignant cells. PI3K signaling may lead to the proliferation of malignant cells and is thought to play a role in the formation and maintenance of a supportive tumor microenvironment. COPIKTRA is indicated in the United States for the treatment of adult patients with relapsed or refractory chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) after at least two prior therapies.. COPIKTRA is also being developed for the treatment of peripheral T-cell lymphoma (PTCL), for which it has received Fast Track designation in the United States. COPIKTRA is being investigated in combination with other agents across several types of solid and hematologic malignancies, through investigator-sponsored studies.
