A New Hope for Elderly Patients with DLBCL: Epcoritamab's Promising Results
Elderly patients with a high-risk form of blood cancer may have a new treatment option on the horizon. The combination of epcoritamab and a modified chemotherapy regimen, R-mini-CHOP, has shown remarkable results in a clinical trial, offering a potential lifeline to those with newly diagnosed diffuse large B-cell lymphoma (DLBCL).
But here's where it gets exciting: the EPCORE NHL-2 trial revealed that this treatment duo delivered deep and rapid responses in these elderly patients, with an overall response rate (ORR) of 93% and a complete response (CR) rate of 86%. And this is the part most people miss—these responses were achieved with manageable side effects, making it a promising option for those who can't tolerate standard treatments.
Unlocking the Potential of Epcoritamab
Deep and Durable Responses: The trial's data, presented at the 2025 ASH Annual Meeting, showed that the combination therapy resulted in impressive response rates, with 93% of patients experiencing a positive reaction to treatment. Even more encouraging, 86% achieved a complete response, meaning no detectable cancer.

Tolerability and Safety: The regimen was generally well-tolerated, with most adverse effects being mild to moderate. While there were some serious side effects, such as neutropenia and infections, they were manageable, and no new safety concerns emerged with longer follow-up.
Diving Deeper into the Study
The EPCORE NHL-2 study enrolled elderly patients with newly diagnosed DLBCL who were unable to receive the full-dose standard treatment due to age or comorbidities. Patients received a fixed duration of epcoritamab, a CD3xCD20 bispecific antibody, along with R-mini-CHOP, a modified chemotherapy regimen.
The results were compelling: at a median follow-up of over 2 years, 79% of patients remained in response to treatment, and 79% remained in CR. The 2-year PFS and OS rates were 76% and 82%, respectively, indicating a potential long-term benefit.
Why Epcoritamab Plus R-mini-CHOP?
While R-mini-CHOP is the standard of care for patients who can't receive the full-dose regimen, outcomes are often suboptimal. Epcoritamab, when added to R-mini-CHOP, has shown promise in improving these outcomes. In previous studies, epcoritamab demonstrated efficacy as a monotherapy and in combination with standard treatments.
For instance, the EPCORE DLBCL-3 trial showed that epcoritamab monotherapy induced durable responses in patients with newly diagnosed large B-cell lymphoma and comorbidities. Additionally, the EPCORE NHL-2 trial found that epcoritamab plus R-mini-CHOP led to an ORR of 89% and a CR rate of 82% in elderly patients who couldn't receive full-dose R-CHOP.
The Bottom Line
The updated EPCORE NHL-2 data suggests that epcoritamab, when combined with R-mini-CHOP, could be a game-changer for elderly, high-risk DLBCL patients. With deep responses and manageable safety, this treatment regimen may offer a new lease of life to those with limited options. But is this the final answer for these patients, or is there more to uncover? The ongoing research and discussions around this topic are crucial to shaping the future of DLBCL treatment.
