  • Updates are supported by data from the Phase 1/2 EPCORE™ NHL-1 clinical trial

AbbVie  announced updates from the U.S. Food and Drug Administration (FDA) and European Medicines Agency (EMA) for epcoritamab, an investigational T-cell engaging bispecific antibody administered subcutaneously, for relapsed or refractory (R/R) follicular lymphoma (FL).

The FDA has granted Breakthrough Therapy Designation (BTD) to epcoritamab-bysp (EPKINLY®) for the treatment of adult patients with R/R FL after two or more therapies. Additionally, the EMA has validated a Type II application for epcoritamab (TEPKINLY®) for the same indication. If approved, R/R FL would become the second conditionally approved indication for epcoritamab in the European Union.

"The FDA granted BTD and validated European application are an important step in our commitment to improving the lives of patients with relapsed/refractory follicular lymphoma, a complex blood cancer with limited treatment options," said Mariana Cota Stirner, M.D., Ph.D., vice president, therapeutic area head for hematology, AbbVie. "Together with Genmab, we are continuing to investigate epcoritamab as a potential core therapy for multiple B-cell malignancies, including diffuse large B-cell lymphoma and now follicular lymphoma."

These updates were supported by previously announced results from the Phase 1/2 EPCORE™ NHL-1 clinical trial evaluating the safety and preliminary efficacy of subcutaneous epcoritamab in 128 adult patients with relapsed, progressive or refractory CD20+ mature B-cell non-Hodgkin's lymphoma (NHL), including FL. Data from the FL cohort of the trial, including an optimized dosing schedule allowing for outpatient administration, will be presented at the upcoming Annual Meeting and Exposition of the American Society of Hematology (ASH) in December 2023.

BTD may expedite the development and review of investigational medicines by the FDA for serious or life-threatening diseases in cases where preliminary clinical evidence shows that a therapy may provide substantial improvements over available therapies.1 EMA validation confirms that the submitted regulatory application is complete and initiates the scientific review process by the EMA's Committee for Medicinal Products for Human Use (CHMP).

FL is typically an indolent, or slow-growing, form of NHL that arises from B-cell lymphocytes.2 It is the second most common form of NHL overall, accounting for 20 percent to 30 percent of all NHL cases globally.3 Although FL is an indolent lymphoma, it is considered incurable with current standard of care therapies.4,5

Epcoritamab is being co-developed by AbbVie and Genmab as part of the companies' oncology collaboration. The companies will share commercial responsibilities in the U.S. and Japan, with AbbVie responsible for further global commercialization.

Phase 1/2 EPCORE™ NHL-1 Trial
EPCORE™ 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.
