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)

Company Announcement

• Decision to submit based on a positive overall response rate (ORR) (p-value < 0.0001), one of the dual primary endpoints in the Phase 3 EPCORE^® FL-1 trial
• Full results from the trial will be submitted for presentation at an upcoming medical conference in 2025

COPENHAGEN, Denmark; May 2, 2024 – Genmab A/S (Nasdaq: GMAB) announced today its intention to submit in the first half of 2025 a supplemental Biologics License Application (sBLA) to the U.S. Food and Drug Administration (FDA) for subcutaneous epcoritamab, a bispecific antibody being investigated in combination with rituximab and lenalidomide (R²) for the treatment of adult patients with relapsed or refractory (R/R) follicular lymphoma (FL), following at least one prior systemic therapy. 

The decision to submit the sBLA is supported by positive topline results from the Phase 3 EPCORE FL-1 trial evaluating epcoritamab plus R² versus R² alone in adult patients with R/R FL. Based on an interim analysis conducted by an Independent Data Monitoring Committee (IDMC) review, the study met one of its dual primary endpoints of ORR (Complete Response plus Partial Response, p-value < 0.0001). The safety profile of epcoritamab plus R² in adult patients with R/R FL was consistent with the known safety profiles of the individual regimens (epcoritamab and R²) and as presented in the U.S. prescribing information for epcoritamab. No new safety signals were observed. The full results will be submitted later this year for presentation at an upcoming medical congress and discussed with global regulatory authorities. 

“We are pleased with the strength of the data that allows us to submit a supplemental Biologics License Application in accordance with the U.S. FDA’s Project Frontrunner, which supports our commitment to advance novel medicines to patients who need them. The interim topline results demonstrate the potential of this investigational epcoritamab combination regimen to treat relapsed or refractory follicular lymphoma patients,” said Jan van de Winkel, Ph.D., Chief Executive Officer, Genmab. “This milestone represents our commitment to the ongoing development of epcoritamab, with our partner AbbVie, and we look forward to seeing the full results from the study.”

Use of epcoritamab plus R² in R/R FL is not approved in the U.S., in the EU or in any other territory. The safety and efficacy of epcoritamab for use as a combination therapy in FL have not been established. Epcoritamab is currently approved by the FDA under Accelerated Approval as a monotherapy for the treatment of adults with R/R FL after two or more lines of systemic therapy.

About Follicular Lymphoma (FL)
FL is typically an indolent (or slow-growing) form of non-Hodgkin's lymphoma (NHL) that arises from B-lymphocytes and is the second most common form of NHL accounting for 20-30 percent of all cases.ⁱ About 15,000 people develop FL each year in the U.S.ⁱⁱ and it is considered incurable with current standard of care therapies.ⁱⁱⁱ Patients often relapse and, with each relapse the remission and time to next treatment is shorter.^iv Over time, transformation to diffuse large B-cell lymphoma (DLBCL), an aggressive form of NHL associated with poor survival outcomes, can occur in more than 25 percent of FL patients.^v

About the EPCORE FL-1 Trial
EPCORE FL-1 (NCT05409066) is a Phase 3 open-label interventional trial to evaluate the safety and efficacy of epcoritamab plus rituximab and lenalidomide (R²) versus R² alone in patients with relapsed/refractory (R/R) follicular lymphoma (FL). The dual primary endpoints are ORR and progression-free survival assessed by independent review committee (IRC) per Lugano criteria.

About Epcoritamab 
Epcoritamab is an IgG1-bispecific antibody created using Genmab's proprietary DuoBody^® technology and administered subcutaneously. Genmab's DuoBody-CD3 technology is designed to direct cytotoxic T cells selectively to elicit an immune response toward target cell types. Epcoritamab is designed to simultaneously bind to CD3 on T cells and CD20 on B cells and induces T-cell-mediated killing of CD20+ cells.^vi 

Epcoritamab (approved under the brand name EPKINLY^® in the U.S. and Japan, and TEPKINLY^® in the EU) has received regulatory approval in certain lymphoma indications in several territories. Epcoritamab is being co-developed by Genmab and AbbVie as part of the companies' oncology collaboration. The companies will share commercial responsibilities in the U.S. and Japan, with AbbVie responsible for further global commercialization. Both companies will pursue additional international regulatory approvals for the investigational R/R FL indication and additional approvals for the R/R DLBCL indication. 

Genmab and AbbVie continue to evaluate the use of epcoritamab as a monotherapy, and in combination, across lines of therapy in a range of hematologic malignancies. This includes five ongoing Phase 3, open-label, randomized trials including a trial evaluating epcoritamab as a monotherapy in patients with R/R DLBCL compared to investigators choice chemotherapy (NCT04628494), a trial evaluating epcoritamab in combination with R-CHOP in adult patients with newly diagnosed DLBCL (NCT05578976), a trial evaluating epcoritamab in combination with rituximab and lenalidomide (R²) in patients with R/R FL (NCT05409066), a trial evaluating epcoritamab in combination with rituximab and lenalidomide (R²) compared to chemoimmunotherapy in patients with previously untreated FL (NCT06191744), and a trial evaluating epcoritamab in combination with lenalidomide compared to chemotherapy infusion in patients with R/R DLBCL (NCT06508658). The safety and efficacy of epcoritamab has not been established for these investigational uses. Please visit www.clinicaltrials.gov for more information.
