Genmab to Showcase Latest Blood Cancer Treatment Advancements at 2025 American Society of Hematology (ASH) Annual Meeting
Media Release
COPENHAGEN, Denmark; November 3, 2025
- More than 20 abstracts, including seven oral presentations, highlight advancements from the epcoritamab development program supporting the expanded clinical profile and potential of epcoritamab for a broader range of B-cell malignancies
- New data demonstrate potential of epcoritamab in first and second-line settings in follicular lymphoma (FL) and first-line in diffuse large B-cell lymphoma (DLBCL)
- Results from Phase 3 EPCORE FL-1 trial, evaluating epcoritamab in combination with rituximab and lenalidomide (R2) in patients with relapsed or refractory (R/R) follicular lymphoma (FL) accepted for oral presentation
(Nasdaq: GMAB) today announced that more than 20 abstracts evaluating epcoritamab-bysp, a T-cell engaging bispecific antibody administered subcutaneously, across lines of therapy and B-cell non-Hodgkin’s lymphoma (NHL) subtypes, will be presented at the 67th Annual Meeting and Exposition of the American Society of Hematology (ASH), in Orlando, Florida, and online, December 6-9.
Data from the epcoritamab development program will showcase its expanding clinical profile and potential utility in earlier lines of therapy with a fixed treatment duration. Presentations include three oral sessions supporting the potential of epcoritamab in the first- and second-line setting in patients with follicular lymphoma (FL) and two oral presentations evaluating epcoritamab in the first-line setting in patients with diffuse large B-cell lymphoma (DLBCL). Additionally, two oral presentations will summarize the efficacy and safety of epcoritamab as monotherapy and in combination for patients with Richter transformation (RT).
“The breadth and depth of data evaluating epcoritamab at this year’s American Society of Hematology meeting spotlight the growing body of clinical evidence supporting the potential of epcoritamab and underscore our commitment to developing epcoritamab as a potential core therapy across a range of B-cell malignancies,” said Dr. Judith Klimovsky, Executive Vice President and Chief Development Officer of Genmab. “We look forward to sharing our data at ASH, including the full pivotal results from the Phase 3 EPCORE FL-1 trial evaluating epcoritamab in combination with rituximab and lenalidomide in patients with relapsed or refractory follicular lymphoma.”

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.i
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 (), a trial evaluating epcoritamab in combination with R-CHOP in adult patients with newly diagnosed DLBCL (), a trial evaluating epcoritamab in combination with rituximab and lenalidomide (R2) in patients with R/R FL (), a trial evaluating epcoritamab in combination with rituximab and lenalidomide (R2) compared to chemoimmunotherapy in patients with previously untreated FL (), and a trial evaluating epcoritamab in combination with lenalidomide compared to chemotherapy infusion in patients with R/R DLBCL (). The safety and efficacy of epcoritamab has not been established for these investigational uses. Please visit for more information.
