Genmab Announces EPKINLY® (epcoritamab-bysp) in Combination with Rituximab and Lenalidomide Approved by the U.S. Food and Drug Administration for the Treatment of Relapsed or Refractory Follicular Lymphoma
. The approval is based on results from the pivotal Phase 3 EPCORE FL-1 study that evaluated fixed duration EPKINLY + R compared to standard of care R .
In the study, treatment with fixed duration EPKINLY + R reduced the risk of disease progression or death by 79% (HR 0.21, 95% CI: 0.13-0.33, p<0.0001) compared to R . Median progression-free survival (PFS) was not reached (NR) among patients treated with EPKINLY + R (95% CI: 21.9-NR) compared to 11.2 months for patients treated with R (95% CI: 10.5-NR). Among patients who were treated with EPKINLY + R , 89% responded to treatment (n=216/243, 95% CI: 84-93, p<0.0001) and 74% achieved a complete response (CR) (n=181/243, 95% CI: 69-80). This is compared to a 74% overall response rate (n=181/245, 95% CI: 68-79) and 43% CR rate among patients treated with R (n=106/245, 95% CI: 37-50). The Phase 3 EPCORE FL-1 study included patients with relapsed or recurrent FL following at least one prior line of treatment across a broad range of patient characteristics and disease risk factors.
The safety profile of EPKINLY + R in the EPCORE FL-1 study was generally consistent with the known safety profiles of the individual regimens (epcoritamab and R ). The most common (≥ 20%) adverse reactions in patients who received EPKINLY + R were rash, upper respiratory tract infections, fatigue, injection site reactions, constipation, diarrhea, cytokine release syndrome (CRS), pneumonia, COVID-19, and fever. The most common Grade 3 to 4 laboratory abnormalities (≥ 10%) were decreased neutrophil count, lymphocyte count, and platelets. CRS occurred in 24% of patients at the recommended 3 step-up dosing schedule, and was primarily low grade (19% Grade 1, 5% Grade 2). A single event of immune effector cell-associated neurotoxicity syndrome (ICANS) occurred in one patient, grade 1 (0.8%). The prescribing information has a Boxed Warning for serious or fatal CRS and ICANS. Warnings and precautions include infections, cytopenias, and embryo-fetal toxicity. Please see additional Important Safety Information below.
“Recurrent follicular lymphoma can be an incurable, complex, and persistent disease, creating a clear need for additional treatments that can change its course earlier in the treatment journey,” said Lorenzo Falchi, M.D., Lymphoma Specialist, Department of Medicine, Memorial Sloan Kettering Cancer Center. “The results shown with EPKINLY + R in the EPCORE FL-1 study are incredibly meaningful, demonstrating durable responses compared to patients treated with R alone. These data, delivered by a regimen that’s chemotherapy-free and can be administered in the outpatient setting, suggest that EPKINLY + R could potentially become a new standard of care.”
FL is typically a slow-growing form of non-Hodgkin lymphoma (NHL) that impacts approximately 15,000 new patients per year in the U.S.. The disease is considered incurable with current standard of care therapies. Patients with FL often relapse, and in some cases, the disease can transform into a more aggressive form of NHL called diffuse large B-cell lymphoma (DLBCL).
“Today’s milestone marks meaningful progress for people living with follicular lymphoma. With a bispecific-based therapy that can be administered in a variety of medical settings, patients have the possibility of accessing this treatment at sites of care closer to where they live,” said Meghan Gutierrez, Chief Executive Officer, Lymphoma Research Foundation.
EPKINLY + R was previously granted Breakthrough Therapy Designation (BTD) by the FDA for the treatment of R/R FL. This designation is granted to investigational medicines for serious or life-threatening diseases in cases where preliminary clinical evidence shows that the therapy may provide substantial improvements over available therapies.
“The FDA approval of EPKINLY + R is an important advancement for patients with follicular lymphoma, enabling treatment at initial recurrence when more effective intervention is needed,” said Judith Klimovsky, M.D., Executive Vice President & Chief Development Officer, Genmab. “This milestone also underscores EPKINLY’s potential as the core therapy for B-cell malignancies, demonstrating benefit in combination and earlier disease, and building on its established role as a single agent option in later lines of treatment.”
In June 2024, EPKINLY monotherapy was granted accelerated approval by the FDA for the treatment of R/R FL following two or more lines of systemic therapy. With the results from the confirmatory Phase 3 EPCORE FL-1 study, the FDA has also converted the accelerated approval into a full approval.
Data from the Phase 3 EPCORE FL-1 study will be presented at the Annual Meeting and Exposition of the American Society of Hematology in December.
EPCORE FL-1 (NCT05409066) is a Phase 3 open-label interventional trial to evaluate the safety and efficacy of epcoritamab plus rituximab and lenalidomide (R ) versus R alone in patients with relapsed/refractory (R/R) follicular lymphoma (FL). Patients were randomized to receive EPKINLY in combination with rituximab and lenalidomide (n=243) or rituximab and lenalidomide alone (n=245). Patients received EPKINLY in 28-day cycles for a total of 12 cycles or until disease progression or unacceptable toxicity, whichever occurred first. Efficacy was established based on the dual primary endpoints of progression free survival (PFS) and overall response rate (ORR) determined by Lugano 2014 criteria as assessed by Independent Review Committee (IRC). Additional efficacy outcome measures include complete response (CR) and duration of response (DOR).
EPKINLY is a prescription medicine used to treat adults with:
It is not known if EPKINLY is safe and effective in children.
should be hospitalized for 24 hours after receiving their first full dose of EPKINLY on Day 15 of Cycle 1 due to the risk of CRS and neurologic problems.
may need to be hospitalized after receiving their first full dose of EPKINLY on Day 22 of Cycle 1 due to the risk of CRS.

Follicular lymphoma (FL) is typically an indolent, or slow-growing, form of non-Hodgkin lymphoma (NHL), that arises from B-lymphocytes. The second most common form of NHL, FL accounts for 20-30% of all NHL cases and is diagnosed in approximately 15,000 people in the U.S. every year. FL is considered incurable with current standard of care therapies. Patients often relapse, and with each relapse the remission and time to next treatment shorten. Over time, transformation to diffuse large B-cell lymphoma (DLBCL), an aggressive form of NHL associated with poor survival outcomes, can occur in more than 25% of FL patients.
EPKINLY (epcoritamab-bysp) is an IgG1-bispecific antibody created using Genmab's proprietary DuoBody technology and administered subcutaneously. Genmab's DuoBody-CD3 technology is designed to direct cytotoxic T cells selectively to elicit an immune response toward target cell types. Epcoritamab is designed to simultaneously bind to CD3 on T cells and CD20 on B cells and induces T-cell-mediated killing of CD20+ cells.
Epcoritamab (approved under the brand name EPKINLY in countries including the U.S. and Japan, and as TEPKINLY in the European Union) has received regulatory approval in certain lymphoma indications in more than 65 countries. Epcoritamab is being co-developed by Genmab and AbbVie as part of the companies' oncology collaboration. The companies will share commercialization responsibilities in the U.S. and Japan, with AbbVie responsible for further global commercialization. Both companies will pursue additional international regulatory approvals for the R/R FL indication and additional approvals for the R/R DLBCL indication.
Genmab and AbbVie continue to evaluate the use of epcoritamab as a monotherapy, and in combination, across lines of therapy in a range of hematologic malignancies. This includes four additional ongoing Phase 3, open-label, randomized trials including a trial evaluating epcoritamab as a monotherapy in patients with R/R DLBCL compared to investigators choice immunochemotherapy (NCT04628494), a trial evaluating epcoritamab in combination with R-CHOP in adult patients with newly diagnosed DLBCL (NCT05578976), a trial evaluating epcoritamab in combination with rituximab and lenalidomide (R ) compared to chemoimmunotherapy in patients with previously untreated FL (NCT06191744), and a trial evaluating epcoritamab in combination with lenalidomide compared to chemotherapy infusion in patients with R/R DLBCL (NCT06508658). The safety and efficacy of epcoritamab has not been established for these investigational uses. Please visit www.clinicaltrials.gov for more information.
