Genmab A/S (NASDAQ:GMAB) today announced new data from a post-hoc subgroup analysis from the pivotal Phase 3 EPCORE® FL-1 trial, evaluating epcoritamab, a subcutaneous T-cell engaging bispecific antibody, in combination with rituximab and lenalidomide (epcoritamab + R2) in adult patients with relapsed or refractory (R/R) follicular lymphoma (FL), which showed that epcoritamab + R2 delivered consistent and sustained efficacy benefits across clinically relevant subgroups, including Follicular Lymphoma International Prognostic Index (FLIPI) score (0–2 vs 3–5), progression of disease less than or equal to two years from the date of initial frontline therapy (POD24) (POD24 vs non-POD24), and patient fitness (non-Hodgkin lymphoma 5 score). These results were presented during an oral presentation (abstract S229) at the European Hematology Association (EHA) 2026 Congress held in Stockholm, Sweden, June 11 -14, 2026.
