Key presentations at ASCO (Free ASCO Whitepaper) and EHA (Free EHA Whitepaper) will highlight data evaluating the potential utility of epcoritamab across multiple settings, including as a monotherapy, in combination regimens, in fixed-duration use and in earlier lines of therapy. Oral sessions will feature the first presentation of the full results from the Phase 3 EPCORE DLBCL-1 trial comparing epcoritamab monotherapy to investigator’s choice chemotherapy in patients with relapsed/refractory (R/R) large B-cell lymphoma (LBCL), as well as additional data from the Phase 3 EPCORE FL-1 trial evaluating epcoritamab in combination with rituximab and lenalidomide (R2) versus R2 alone in patients with R/R follicular lymphoma (FL). Additional presentations will include real-world evidence and health economic and outcomes research data, as well as overviews of trials-in-progress evaluating late-stage medicines.
"This year at ASCO (Free ASCO Whitepaper) and EHA (Free EHA Whitepaper), Genmab will once again present data highlighting the depth and breadth of the epcoritamab development program, including encouraging results across multiple treatment settings for patients with B-cell malignancies. These findings underscore the versatility of epcoritamab as a monotherapy, in combination regimens and as a potential core therapy across the spectrum of B-cell malignancies," said Dr. Judith Klimovsky, Executive Vice President and Chief Development Officer of Genmab. "Additional presentations and publications at ASCO (Free ASCO Whitepaper) will further reflect our commitment to advancing other antibody-based therapeutics."
All abstracts accepted for presentation and publication have been published and may be accessed online via the ASCO (Free ASCO Whitepaper) Meeting Library and EHA (Free EHA Whitepaper) Open Access Library.

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 epcoritamab as a monotherapy, and in combination, across lines of therapy in a range of hematologic malignancies. This includes several ongoing Phase 3, open-label, randomized trials, among them a trial evaluating epcoritamab in combination with R-CHOP in adult patients with newly diagnosed DLBCL (NCT05578976), a trial evaluating epcoritamab in combination with lenalidomide compared to chemotherapy infusion in patients with R/R DLBCL (NCT06508658), and a trial evaluating epcoritamab in combination with lenalidomide and rituximab (R2) compared to chemoimmunotherapy in patients with previously untreated FL (NCT06191744). The safety and efficacy of epcoritamab has not been established for these investigational uses. Please visit www.clinicaltrials.gov for more information.
Please see local country prescribing information for all labeled indication and safety information.
About Rinatabart Sesutecan (Rina-S; GEN1184)
Rina-S; GEN1184 is an investigational ADC. It is composed of a novel human monoclonal antibody directed at FRα, a hydrophilic protease-cleavable linker, and exatecan, a topoisomerase I inhibitor payload. The clinical development program for Rina-S continues to expand, with multiple ongoing Phase 3 studies in patients with ovarian and endometrial cancer, alongside evaluation in other tumor types with unmet needs. The safety and efficacy of rinatabart sesutecan have not been established. Please visit View Source for more information.
About Petosemtamab (GEN1158)
Petosemtamab is an investigational bispecific antibody targeting the epidermal growth factor receptor (EGFR) and the leucine-rich repeat containing G-protein-coupled receptor 5 (LGR5). By engaging both receptors, petosemtamab is designed to inhibit EGFR signaling and trigger EGFR degradation selectively in LGR5+ cancer stem-like cells to support multiple anti-tumor mechanisms, including enhanced immune-mediated activity. It is currently being investigated in head and neck squamous cell carcinoma (HNSCC) and other solid tumors, including colorectal cancer (CRC) and non-small cell lung cancer (NSCLC). The safety and efficacy of petosemtamab have not been established. Please visit View Source for more information.
