U.S. FDA Accepts for Priority Review Biologics License Application for Epcoritamab (DuoBody®-CD3xCD20) for the Treatment of Relapsed/Refractory Large B-Cell Lymphoma

  • The application is supported by data from the Phase 1/2 EPCORE™ NHL-1 trial evaluating the safety and preliminary efficacy of subcutaneous epcoritamab in patients with non-Hodgkin’s B-cell lymphoma mature relapsed, progressive or refractory CD20+, including large B-cell lymphoma

  • If approved for relapsed/refractory large B-cell lymphoma after two or more lines of systemic therapy, epcoritamab could become the first subcutaneous bispecific antibody available for the treatment of large B-cell lymphoma

NORTH CHICAGO, Illinois., November 21, 2022 /PRNewswire/ — AbbVie (NYSE:ABBV) today announced that the U.S. Food and Drug Administration (FDA) has accepted for priority review the Biologics License Application for epcoritamab (DuoBody®-CD3xCD20), an investigational subcutaneous bispecific antibody, for the treatment of adult patients with relapsed/refractory large B-cell lymphoma (LBCL) after two or more lines of systemic therapy.

The application is supported by previously announced results from the LBCL cohort of the multicenter, open-label, Phase 1/2 EPCORE™ NHL-1 trial evaluating the safety and preliminary efficacy of investigational epcoritamab in adult patients with CD20+ relapsed, progressing, or refractory mature B-cell non-Hodgkin’s lymphoma (NHL).

“We are committed to the research and development of innovative therapies to provide important treatment options for people with blood cancers, such as large B-cell lymphoma, which has limited treatment options under the relapsed/refractory,” said mohamed zaki, MD, Ph.D., Vice President and Head of Global Oncology Development, AbbVie. “This milestone marks a first step in our hope to develop a core therapy for people with malignant B-cell tumors.”

Additionally, the European Medicines Agency recently validated a marketing authorization application for epcoritamab for the treatment of adult patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL) – a major subtype of LBCL – after two or more lines of systemic therapy.

Epcoritamab is co-developed by AbbVie and Genmab as part of the companies’ oncology collaboration. The companies will share commercial responsibilities in the United States and Japan, with AbbVie responsible for continued global commercialization. The companies are committed to evaluating epcoritamab as monotherapy and in combination, across treatment lines in a range of hematological malignancies. This includes an ongoing Phase 3 open-label randomized clinical trial evaluating epcoritamab monotherapy in patients with relapsed/refractory DLBCL (NCT: 04628494) and an open-label Phase 3 clinical trial evaluating epcoritamab in combination in patients with relapsed/refractory DLBCL. refractory follicular lymphoma (NCT: 05409066).

About Large B-Cell Lymphoma (LBCL)
LBCL is a fast-growing type of NHL, a cancer that grows in the lymphatic system and affects B cells, a type of white blood cell.1 There are an estimated 150,000 new cases of LBCL each year worldwide.1 LBCL includes DLBCL, which is the most common type of NHL in the world and accounts for approximately 30% of all NHL cases.1

About the EPCORE™ NHL-1 Trial
EPCORE™ NHL-1 is an open-label multicenter preliminary safety and efficacy trial of epcoritamab, including a first-in-man phase 1, dose escalation portion; a part of expansion of phase 2; and an optimization part. The trial was designed to evaluate subcutaneous epcoritamab in patients with relapsed, progressive, or refractory CD20+ mature B-cell NHL, including LBCL and DLBCL. Data from the dose escalation portion of the study, which determined the recommended Phase 2 dose, has been published in The Lancet in 2021. In the Phase 2 expansion, additional patients are being treated with epcoritamab to further explore the safety and efficacy of epcoritamab in three cohorts of patients with different types of NHL at relapsed/refractory B cells who had limited treatment options.

The primary endpoint for the expansion portion of Phase 2 was the overall response rate as assessed by an independent review board. Secondary endpoints included duration of response, complete response rate, progression-free survival, overall survival, time to response, time to next therapy, and minimal residual disease negativity rate.

About Epcoritamab
Epcoritamab is an investigational IgG1 bispecific antibody created using Genmab’s proprietary DuoBody® Technology. Genmab DuoBody®-CD3 technology is designed to selectively direct cytotoxic T cells to trigger an immune response against target cell types. Epcoritamab is designed to simultaneously bind CD3 on T cells and CD20 on B cells, and induce T cell-mediated killing of CD20+ cells.2 CD20 is expressed on B cells and is a clinically validated therapeutic target in many B-cell malignancies, including diffuse large B-cell lymphoma, follicular lymphoma, mantle cell lymphoma, and chronic lymphocytic leukemia.3,4 Epcoritamab is co-developed by AbbVie and Genmab as part of the companies’ oncology collaboration.
