Genmab and AbbVie report 51% lower risk of progression with epcoritamab plus R‑CHOP in frontline DLBCL

Genmab and AbbVie announced topline data from the Phase 3 EPCORE DLBCL‑2 study showing that adding epcoritamab to standard R‑CHOP cuts the risk of disease progression or death by 51% in newly diagnosed diffuse large B‑cell lymphoma patients with an International Prognostic Index of 2‑5. The hazard ratio was reported as 0.49 with a p‑value below 0.0001. Both companies said they will discuss the results with global regulators and plan to present the data at a future medical meeting.

The company says the hazard‑ratio reduction could position the combination as a new frontline option for high‑risk DLBCL, potentially expanding the market for epcoritamab. Analysts note the strong efficacy signal may boost investor sentiment toward both firms.

  • 1The trial showed a 51% reduction in the risk of progression or death (HR 0.49).
  • 2The p‑value for the primary endpoint was reported as less than 0.0001.
  • 3Patients enrolled had an International Prognostic Index score of 2 to 5.
  • 4The study randomized participants in a 2:1 ratio to epcoritamab + R‑CHOP versus R‑CHOP alone.
  • 5The trial began on February 8 2023 and is still ongoing.
  • 6Epcoritamab is currently approved for other lymphoma indications but not for this combination.
