Topline Phase 3 Data Show Adding Epcoritamab to Standard R-CHOP Cut Lymphoma Progression or Death Risk by 51%
The late-stage trial was the first to show a statistically significant progression-free survival benefit for a bispecific antibody combination in frontline DLBCL.
On Monday, October 5, 2026, Genmab and AbbVie announced positive Phase 3 results from the EPCORE DLBCL-2 trial, showing epcoritamab combined with R-CHOP significantly improved progression-free survival in newly diagnosed patients with diffuse large B-cell lymphoma .
Epcoritamab is an immune-based therapy that helps T cells attack cancer cells, addressing a critical need for additional frontline treatment options for approximately 25,000 new DLBCL cases diagnosed annually in the United States.
The combination reduced the risk of disease progression or death by 51% compared with R-CHOP alone, with a hazard ratio of 0.49 and a p-value of less than 0.0001, according to the companies.
Dr. Gilles Salles, Chief of the Lymphoma Service at Memorial Sloan Kettering Cancer Center, called the results "clinically meaningful" and "highly relevant to everyday practice," signaling potential to reshape frontline treatment.
Genmab and AbbVie will engage global regulatory authorities to determine next steps for the investigational combination, as the companies work to bring this potential practice-changing therapy to patients.
