Epcoritamab

Topline results from Phase 3 EPCORE® DLBCL-4 trial evaluating epcoritamab in combination with lenalidomide demonstrated statistically significant and clinically meaningful improvement in progression-free survival (PFS) in patients with relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL) EPCORE DLBCL-4 demonstrated improved PFS with a chemotherapy-free combination treatment regimen in patients with R/R DLBCL NORTH CHICAGO, Ill., June 29, 2026 /PRNewswire/ -- AbbVie (NYSE: ABBV) today announced topline results from the Phase 3 EPCORE DLBCL-4 trial evaluating the combination of epcoritamab, a T-cell engaging bispecific antibody, and lenalidomide, compared to rituximab plus gemcitabine plus oxaliplatin (R-GemOx) in adult patients with relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL) who received at least one prior line of therapy. Based on topline results from the prespecified primary analysis, the trial met its primary endpoint, demonstrating statistically significant and clinically meaningful improvement in progression-free survival (PFS). The risk of disease progression and death was reduced by 60% (HR 0.40 [95% CI 0.30, 0.55]; p-value <0.0001) and 56% (HR 0.44 [95% CI 0.33, 0.60]; p-value <0.0001), based on different censoring rules in the U.S. and outside the U.S., respectively. The safety profile of epcoritamab when administered in combination with lenalidomide was consistent with the known safety profiles of the individual agents (epcoritamab and lenalidomide). "Despite recent advances, there remains a critical need for innovative therapies to improve outcomes for those battling DLBCL, an aggressive and often difficult-to-treat cancer," said Daejin Abidoye, M.D., vice president, therapeutic area head, oncology, solid tumor and hematology, AbbVie. "Today's encouraging topline results highlight the potential of epcoritamab, a fixed-treatment therapy, in combination with lenalidomide, as a meaningful treatment option after initial disease progression." AbbVie and Genmab will engage global regulatory authorities to discuss next steps. Data will be submitted for presentation at a future medical meeting. About the EPCORE ® DLBCL-4 Trial EPCORE DLBCL-4 (NCT06508658) is a global Phase 3 open label, multi-center, randomized trial to evaluate the efficacy of epcoritamab (GEN3013, DuoBody®-CD3xCD20) in combination with lenalidomide compared to chemoimmunotherapy, rituximab plus gemcitabine plus oxaliplatin (R-GemOx), in adult patients with relapsed or refractory large B-cell lymphoma (LBCL), including patients with diffuse large B-cell lymphoma, not otherwise specified (DLBCL, NOS), high-grade B-Cell lymphoma (HGBL) with MYC and B-cell/lymphoma 2 (BCL2) and/or BCL6 rearrangements, follicular lymphoma grade 3B (FL3B), T-cell/histiocyte-rich large B-Cell lymphoma (TCHR LBLC), and Epstein-Barr Virus-positive diffuse large B-cell lymphoma (EBV+ DLBCL). Patients in the trial were previously treated with at least one line of systemic antineoplastic therapy including anti-CD20 mAb-containing combination chemotherapy, and failed or relapsed after, or were not a candidate for autologous stem cell transplantation (ASCT) and ineligible for or unable to receive CAR-T since DLBCL diagnosis. Patients received subcutaneous epcoritamab (cycles 1–3, once weekly; cycles 4–12, once every 4 weeks) and oral lenalidomide (25 mg/day on days 1–21) for a total of twelve 28-day cycles or intravenously infused R-GemOx for up to four cycles (each cycle lasting 28 days). The trial started on August 13, 2024, and is ongoing. More information on this trial can be found at . (NCT06508658).

COPENHAGEN, Denmark--(BUSINESS WIRE)--Genmab A/S (Nasdaq: GMAB) today announced new data from two studies evaluating epcoritamab, a T-cell engaging antibody administered subcutaneously, in the first-line (1L) treatment of patients with diffuse large B-cell lymphoma (DLBCL) who may have limited treatment options due to advanced age or multiple health conditions. Results from the Phase 2 EPCORE® DLBCL-3 study showed an overall response rate (ORR) of 67% and a complete response (CR) rate of 58% with epcoritamab monotherapy in elderly patients with newly diagnosed DLBCL. In the Phase 1b/2 EPCORE NHL-2 study, epcoritamab plus rituximab plus dose-attenuated cyclophosphamide, doxorubicin, vincristine, and prednisone (R-mini-CHOP) demonstrated an ORR of 93% and a CR rate of 86% in elderly patients with newly diagnosed DLBCL. The results from both studies were presented in two poster presentations (abstracts PS2082 and PF1007) at the European Hematology Association (EHA) 2026 Congress held in Stockholm, Sweden, June 11-14. Additionally, the full EPCORE DLBCL-3 results have been simultaneously published in The Lancet Haematology. EPCORE DLBCL-3 Results The Phase 2 EPCORE DLBCL-3 study (abstract PS2082) evaluated the efficacy and safety of fixed-duration epcoritamab monotherapy in newly diagnosed CD20+ large B-cell lymphoma (LBCL) patients ineligible for anthracycline-based chemotherapy due to age (≥80 years) or comorbidities (≥75 years with comorbidities). Among 66 enrolled patients, the median age was 82.5 years, and all had comorbid conditions (94% with ≥3 comorbidities). With a median follow-up of 21.9 months, epcoritamab monotherapy demonstrated responses in this population with high unmet medical need. An ORR of 67% and a CR rate of 58% were observed in evaluable patients (n=66). Median time to response was 1.5 months, and median time to CR was 2.2 months. Notably, 11 of 17 patients with a partial response or stable disease at first assessment subsequently achieved a CR. "For newly diagnosed elderly patients with diffuse large B-cell lymphoma and comorbidities, who are often excluded from standard curative chemotherapy and ineligible for doxorubicin, finding more options is paramount," said Umberto Vitolo, M.D. Candiolo Cancer Institute, FPO-IRCCS, Candiolo (Turin), Italy. "The EPCORE DLBCL-3 study showed that epcoritamab monotherapy offers robust data. Importantly, its safety profile, including cytokine release syndrome and immune effector cell–associated neurotoxicity syndrome, was consistent with expected rates in this fragile population with a high unmet medical need for new therapeutic options." Responses were durable, with median duration of response (DOR) and duration of complete response (DOCR) not reached. At 12 months, an estimated 67% of responses and 73% of CRs remained ongoing. Median progression-free survival (PFS) was 13.0 months, while median overall survival (OS) was not reached; an estimated 43% of patients remained progression-free and 62% were alive at 18 months. High rates of minimal residual disease (MRD) negativity were observed, with 92% of evaluable responders achieving MRD negativity, typically by Cycle 3 Day 1 and sustained through Cycle 12 Day 1 in most patients. The safety profile was consistent with expected rates in this elderly population. Cytokine release syndrome (CRS) occurred in 71% of patients, most commonly during Cycle 1, and immune effector cell-associated neurotoxicity syndrome (ICANS) occurred in 18%. Infections of any grade occurred in 68% of patients (26% Grade ≥3), and neutropenia was reported in 16%, with no febrile neutropenia or clinical tumor lysis syndrome observed. Eight Grade 5 TEAEs occurred. EPCORE NHL-2, Arm 8 Results Arm 8 of the Phase 1b/2 EPCORE NHL-2 study (abstract PF1007) evaluated epcoritamab plus R-mini-CHOP in 28 newly diagnosed CD20+ DLBCL patients ineligible for full-dose R-CHOP due to age (≥75 years) or comorbidities (≥65 years with comorbidities). With more than two years of follow-up, fixed-duration epcoritamab plus R-mini-CHOP demonstrated high response rates, sustained MRD negativity and durable remissions. An ORR of 93% and a CR rate of 86% were observed. Median DOR, DOCR, PFS, and OS were not reached. At two years, estimated DOR and DOCR rates were 79%, while estimated PFS and OS rates were 76% and 82%, respectively. “The EPCORE NHL-2 Arm 8 results are very encouraging, showing that combining epcoritamab with R-mini-CHOP led to high overall response rates and complete response rates, rapid and sustained minimal residual disease negativity, and durable remissions in this population,” said David Belada, M.D., Department of Internal Medicine—Haematology, Charles University, Hospital and Faculty of Medicine, Hradec Králové, Czech Republic. “These outcomes, alongside a consistent safety profile, potentially support the integration of epcoritamab with standard of care for these vulnerable patients, and highlight its broad utility in combinations across a range of disease settings and patient populations." Rapid and sustained MRD negativity was observed, with 95% of evaluable patients achieving MRD negativity, including high rates in high-risk subgroups. Outcomes compared favorably with historical results for R-mini-CHOP alone. The safety profile was consistent with prior reports and the known safety profiles of epcoritamab and R-mini-CHOP. The most common Grade ≥3 treatment-emergent adverse events (TEAEs) were neutropenia (54%), serious infections (33%) and anemia (14%). Most Grade ≥3 serious infections occurred during the first six cycles of treatment with R-mini-CHOP coadministration. TEAEs led to epcoritamab discontinuation in three patients (11%). “Genmab is committed to evaluating epcoritamab as a potential treatment option in earlier lines of therapy for patients who traditionally struggle with aggressive treatment," said Dr. Judith Klimovsky, Executive Vice President and Chief Development Officer of Genmab. "The robust data observed in both the monotherapy and combination approaches reinforce our vision of making epcoritamab a foundational therapy across the spectrum of B-cell malignancies. These Phase 2 results support our ongoing commitment to addressing the significant unmet medical needs of elderly and comorbid patients, as we seek to identify effective, less intensive and tolerable options." About Diffuse Large B-Cell Lymphoma Diffuse large B-cell lymphoma (DLBCL) DLBCL is the most common type of non-Hodgkin lymphoma (NHL) worldwide, accounting for approximately 25-30 percent of all NHL cases.i,ii DLBCL can arise in lymph nodes as well as in organs outside of the lymphatic system, occurs more commonly in the elderly and is slightly more prevalent in men.iii,iv DLBCL is a fast-growing type of NHL, a cancer that develops in the lymphatic system and affects B-cell lymphocytes, a type of white blood cell. For many people living with DLBCL, their cancer either relapses, which means it may return after treatment, or becomes refractory, meaning it does not respond to treatment. Although new therapies have become available, treatment management can remain a challenge.iv,v About the EPCORE® DLBCL-3 Trial EPCORE DLBCL-3 (NCT05660967) is an open-label, randomized, global, Phase 2 trial to evaluate the efficacy and safety of epcoritamab as monotherapy or in combination with lenalidomide as first-line therapy for anthracycline-ineligible subjects with diffuse large B-cell lymphoma (DLBCL). This is a 2-stage trial. In Stage 1, eligible patients were randomized to either epcoritamab monotherapy or epcoritamab plus lenalidomide. In Stage 2, additional patients were enrolled to the epcoritamab monotherapy arm. Each treatment cycle is 28 days. Patients will receive a maximum of 12 cycles (up to 1 year) of treatment. The primary objective is to evaluate the clinical efficacy of epcoritamab monotherapy or epcoritamab and lenalidomide. The primary endpoint is to achieve a complete response rate determined by Lugano criteria. Additional secondary endpoints include overall response rate, duration of response, duration of complete response, rate of minimal residual disease negativity, progression-free survival and overall survival. More information on this trial can be found at www.clinicaltrials.gov/. About the EPCORE® NHL-2 Trial EPCORE NHL-2 (NCT04663347) is a Phase 1b/2 open-label interventional trial to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics/biomarkers, immunogenicity, and preliminary efficacy of epcoritamab as a monotherapy and in combination with other standard of care agents in patients with B-cell non-Hodgkin lymphoma (B-NHL). The trial consists of two parts: Part 1 (Dose Escalation) and Part 2 (Dose Expansion). The primary objective of Part 1 is safety, and the primary goal of Part 2 is preliminary efficacy. The primary efficacy endpoint is overall response rate (ORR) based on best overall response per Lugano criteria. MRD negativity was assessed as a secondary endpoint. More information on this trial can be found at www.clinicaltrials.gov.
