Genmab to Submit Supplemental Biologics License Application (sBLA) to U.S. Food and Drug Administration for Epcoritamab Plus Rituximab and Lenalidomide (R2) in Patients with Relapsed/Refractory Follicular Lymphoma (FL)

Core Viewpoint - Genmab A/S plans to submit a supplemental Biologics License Application (sBLA) for subcutaneous epcoritamab in combination with rituximab and lenalidomide for treating adult patients with relapsed or refractory follicular lymphoma in the first half of 2025 [1][3] Company Announcement - The sBLA submission is based on positive topline results from the Phase 3 EPCORE FL-1 trial, which showed that epcoritamab plus rituximab (R) met one of its dual primary endpoints of overall response rate (ORR) with a p-value of less than 0.0001 [2][7] - The safety profile of the combination therapy was consistent with known safety profiles of the individual components, and no new safety signals were observed [2][3] About Follicular Lymphoma (FL) - Follicular lymphoma is a slow-growing form of non-Hodgkin's lymphoma, accounting for 20-30% of all cases, with approximately 15,000 new cases diagnosed annually in the U.S. [4] - It is considered incurable with current standard therapies, and patients often experience shorter remission periods with each relapse [4] About the EPCORE FL-1 Trial - The EPCORE FL-1 trial is a Phase 3 open-label interventional study evaluating the safety and efficacy of epcoritamab plus rituximab and lenalidomide versus rituximab alone in patients with relapsed/refractory follicular lymphoma [5] About Epcoritamab - Epcoritamab is an IgG1-bispecific antibody developed using Genmab's DuoBody technology, designed to target CD3 on T cells and CD20 on B cells, inducing T-cell-mediated killing of CD20+ cells [6][7] - It is currently approved by the FDA as a monotherapy for adults with relapsed or refractory follicular lymphoma after two or more lines of systemic therapy [3][7] Collaboration and Future Plans - Genmab is co-developing epcoritamab with AbbVie, sharing commercial responsibilities in the U.S. and Japan, and both companies are pursuing additional international regulatory approvals for the investigational indication [8][9] - Genmab and AbbVie are also evaluating epcoritamab in various hematologic malignancies across multiple ongoing Phase 3 trials [9]
