New Data for Bispecific Antibody Epcoritamab (DuoBody® CD3xCD20) Shows Strong, Durable Treatment Response for Patients with Difficult-To-Treat Relapsed/Refractory (R/R) Follicular Lymphoma (FL)


Data from Phase 1/2 EPCOREtm NHL-1 study show patients treated with epcoritamab experienced 82% overall response rates (ORR) including 63% complete response (CR) rates as presented at the 65th American Society of Hematology (ASH) congress
Follicular lymphoma is the second most common form of non-Hodgkin's lymphoma

NORTH CHICAGO, Ill., Dec. 9, 2023 /PRNewswire/ -- AbbVie (NYSE: ABBV) and Genmab A/S (Nasdaq: GMAB) announced today that adult patients with relapsed/refractory (R/R) follicular lymphoma (FL) previously treated with two or more prior therapies experienced strong and durable responses with high overall response (ORR) and complete response (CR) rates when treated with epcoritamab (DuoBody® CD3xCD20), an investigational, subcutaneously administered T-cell engaging bispecific antibody. More than half of patients who responded to treatment in the study remained responsive to treatment at the time of data analysis (i.e., median duration of response was not reached). Data from the dose-expansion cohort of the Phase 1/2 EPCOREtm NHL-1 clinical trial are being shared during a poster presentation on Saturday, December 9 at 5:30 PM PT at the ASH congress in San Diego, California. Updated data from this study include an optimized, step-up dosing schedule showing reduced incidence and severity of cytokine release syndrome (CRS), a notable side effect from immune-engaging cancer treatments.

"Despite treatment advances for patients with follicular lymphoma whose disease has unfortunately progressed, treating relapsed or refractory follicular lymphoma remains highly challenging, particularly as a third-line treatment," said Catherine Thieblemont, M.D., Ph.D., head of the hemato-oncology department, Paris University, Hôpital Saint-Louis Assistance-Publique-Hopitaux de Paris (APHP) in Paris. "The patients in this trial represent a historically difficult-to-treat patient population. The data presented today are especially notable because they demonstrated high overall and complete response rates for this investigational therapy and a preview for its potential as a treatment option."

"Further developing epcoritamab as a core therapy to help treat more patients with B-cell malignancies, including follicular lymphoma, is an important goal we share with our partner Genmab," said Mariana Cota Stirner, M.D., Ph.D., vice president, therapeutic area head for hematology, AbbVie. "These data at this year's ASH further build our confidence in epcoritamab's treatment potential as well as development for earlier patient treatment."

Results from this cohort of 128 adult patients show the following:

No new safety signals were detected. The most common treatment-emergent AE (TEAE) was CRS with 67% occurrence (40% Grade 1, 25% Grade 2, 2% Grade 3). Following an optimized step-up dose regimen in a separate cohort to reduce the risk and severity of CRS, 24 out of 50 patients (48%) experienced grade 1-2 CRS (40% Grade 1, 8% Grade 2, 0% Grade 3). As well, no cases of Immune Effector Cell-Associated Neurotoxicity Syndrome (ICANS) were reported. This data may support investigating optimized step-up dose in an outpatient setting. Additional common TEAEs (>20%) were injection-site reaction (57%), COVID-19 (40%), fatigue (30%), neutropenia (29%), diarrhea (27%) and pyrexia (25%). TEAEs leading to treatment discontinuation occurred in 19% of patients, and death related to TEAEs occurred in 13 patients (10%).

AbbVie and Genmab recently announced that the U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy Designation (BTD) to epcoritamab for the treatment of adult patients with R/R FL after two or more therapies. Additionally, the European Medicines Agency (EMA) has validated a Type II application for epcoritamab in the same indication. If approved, R/R FL would become the second conditionally approved indication for epcoritamab in the European Union. More information is available here.

About the Phase 1/2 EPCOREtm NHL-1 Trial
EPCOREtm NHL-1 is an open-label, multi-center safety and preliminary efficacy trial of epcoritamab that consists of three parts: a Phase 1 first-in-human, dose escalation part; a Phase 2a expansion part; and a Phase 2a dose optimization part. The trial was designed to evaluate subcutaneous epcoritamab in adult patients with relapsed, progressive or refractory CD20+ mature B-cell non-Hodgkin's lymphoma (NHL), including follicular lymphoma (FL). In the Phase 2a expansion part, additional patients are being enrolled to further explore the safety and efficacy of epcoritamab in three cohorts of patients with different types of relapsed or refractory (R/R) B-cell NHLs who have limited therapeutic options. The dose optimization part evaluates the potential for alternative step-up dosing regimens to help further minimize Grade 2 cytokine release syndrome (CRS) and mitigate Grade ?3 CRS. The application for BTD included additional data from this cohort of patients. The primary endpoint of the expansion part was overall response rate as assessed by an independent review committee. Secondary efficacy endpoints included duration of response, complete response rate, duration of complete response, progression-free survival, and time to response as determined by the Lugano criteria. Overall survival, time to next therapy, and rate of minimal residual disease negativity were also evaluated as secondary efficacy endpoints.

About Follicular Lymphoma (FL)
FL is typically an indolent (or slow growing) form of non-Hodgkin's lymphoma (NHL) that arises from B-lymphocytes.1 FL is the second most common form of NHL, accounting for 20-30% of all NHL cases, and represents 10-20% of all lymphomas in the western world.1,2,3 Although FL is typically considered an indolent (or slow-growing) lymphoma, it remains incurable with conventional therapy4,5 and patients who achieve remission often experience relapse.6

About Epcoritamab
Epcoritamab is an investigational 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.7

Epcoritamab (approved under the brand name EPKINLY® in the United States and TEPKINLY® in the European Union) has received regulatory approval in adults with certain types of large B-cell lymphoma (LBCL), including diffuse large B-cell lymphoma (DLBCL), globally. EPKINLY is approved under the FDA's Accelerated Approval program based on response rate and durability of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials. Use of epcoritamab in FL is not approved in the U.S. or in the EU. AbbVie will continue to pursue regulatory submissions for epcoritamab across international markets.

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 three ongoing Phase 3, open-label, randomized trials including a trial evaluating epcoritamab as a monotherapy in patients with R/R DLBCL (NCT: 04628494) compared to investigator's choice chemotherapy, a Phase 3 trial evaluating epcoritamab in combination with R-CHOP in adult patients with newly diagnosed DLBCL (NCT: 05578976), and a Phase 3 clinical trial evaluating epcoritamab in combination with rituximab and lenalidomide (R2) in patients with R/R FL (NCT: 05409066). Epcoritamab is not approved to treat patients with newly diagnosed DLBCL or with FL. The safety and efficacy of epcoritamab has not been established for these investigational uses. Please visit clinicaltrials.gov for more information.
