NORTH CHICAGO, Ill., May 19, 2023 /PRNewswire/ -- AbbVie (NYSE: ABBV) today announced that the U.S. Food and Drug Administration (FDA) has approved EPKINLYTM (epcoritamab-bysp), as the first and only T-cell engaging bispecific antibody for the treatment of adult patients with relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL), not otherwise specified (NOS), including DLBCL arising from indolent lymphoma, and high-grade Bcell lymphoma (HGBL), after two or more lines of systemic therapies.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. EPKINLY is being co-developed by AbbVie and Genmab as part of the companies' oncology collaboration.

DLBCL is a type of aggressive, fast-growing non-Hodgkin's lymphoma (NHL), a cancer that develops in the lymphatic system and affects B cells, a type of white blood cell. DLBCL is the most common type of NHL, comprising of an estimated 30,400 U.S. cases in 2022 and 150,000 new cases each year globally. DLBCL patients are typically treated with chemoimmunotherapy-based regimens. For R/R patients, several targeted therapies including T-cell mediated treatments have recently emerged. However, single agent and ready-available or off-the-shelf treatment options are limited.1,2,3,4,5

"DLBCL is an aggressive cancer type that can rapidly progress and resist treatment. The FDA approval of EPKINLY represents a new treatment mechanism of action for third line DLBCL patients. As a non-chemotherapy, single-agent treatment for DLBCL patients, we hope that EPKINLY can effectively treat this aggressive cancer type and can be used for patient care quickly and in an off the shelf form for physicians," said Thomas Hudson, M.D., senior vice president, research and development, chief scientific officer, AbbVie. "The approval is just the first step, with our partner Genmab, towards a shared goal of developing a core therapy for patients with B-cell malignances."

AbbVie is committed to transforming standards of care across blood cancers and advancing a dynamic cancer research and treatment pipeline. EPKINLY marks the third approved blood cancer treatment available as part of AbbVie's growing oncology portfolio, aswe strive to make a remarkable impact for people living with cancer.

"Patients with DLBCL who relapse or are refractory to currently available therapies have limited options. Generally, the prognosis for these patients is poor and management of this aggressive disease can be challenging," said Tycel Phillips, M.D., City of Hope Associate Professor, Division of Lymphoma, Department of Hematology & Hematopoietic Cell Transplantation. "Epcoritamab is a subcutaneous bispecific antibody that offers an additional treatment option for this patient population. With this approval, patients who are in need of additional therapy may have the opportunity to receive epcoritamab after failure to respond or relapse after two or more systemic therapies."

"The FDA approval of EPKINLY represents a new treatment for diffuse large B-cell lymphomas among patients who have relapsed or have refractory disease and are looking for a new medication," said Meghan Gutierrez, chief executive officer, Lymphoma Research Foundation.

Highlights of the Phase 1/2 EPCORE NHL-1 clinical trial supporting the approval:

About EPKINLYTM (epcoritamab-bysp)EPKINLY is a prescription medicine used to treat adults with certain types of diffuse large B-cell lymphoma (DLBCL) and high-grade B-cell lymphoma (HGBL) that has come back (relapsed) or that did not respond to previous treatment (refractory), and who have received 2 or more treatments for their cancer. EPKINLY is approved based on patient response data. A study is ongoing to confirm the clinical benefit of EPKINLY. It is not known if EPKINLY is safe and effective in children.

EPKINLY is an IgG1-bispecific antibody created using Genmab's proprietary DuoBody technology. Genmab's DuoBody-CD3 technology is designed to direct cytotoxic T cells selectively to elicit an immune response towards target cell types. It is designed to simultaneously bind to CD3 on T cells and CD20 on B-cells and induces T cell mediated killing of CD20+ cells.5,6,7

AbbVie and Genmab are evaluating EPKINLY as a monotherapy, and in combination, across multiple lines of therapy in a range of hematologic malignancies. This includes an ongoing Phase 3, open-label, randomized controlled trial evaluating EPKINLY as a monotherapy in patients with R/R DLBCL (NCT: 04628494) and two Phase 3, open-label, randomized controlled trials evaluating EPKINLY combination regimens in patients with newly diagnosed DLBCL (NCT: 05660967) and R/R follicular lymphoma (NCT: 05409066). The companies will share commercial responsibilities in the U.S. and Japan, with AbbVie responsible for further global commercialization.AbbVie will continue to pursue regulatory submissions for epcoritamab across international markets throughout the year.

IMPORTANT SAFETY INFORMATION

Important WarningsEPKINLY can cause serious side effects, including:

Due to the risk of CRS, you will receive EPKINLY on a "step-up" dosing schedule. The step-up dosing schedule is when you receive smaller "step-up" doses of EPKINLY on day 1 and day 8 of your first cycle of treatment (cycle 1). You will receive your first full dose of EPKINLY on day 15 of cycle 1. If your dose of EPKINLY is delayed for any reason, you may need to repeat the step-up dosing schedule. Before each dose in cycle 1, you will receive medicines to help reduce your risk of CRS. Your healthcare provider will decide if you need to receive medicine to help reduce your risk of CRS with future cycles.

Due to the risk of CRS and neurologic problems, you should be hospitalized for 24 hours after receiving your first full dose of EPKINLY on day 15 of cycle 1. Your healthcare provider will monitor you for symptoms of CRS and neurologic problems during treatment with EPKINLY, as well as other side effects, and treat you if needed. Your healthcare provider may temporarily stop or completely stop your treatment with EPKINLY if you develop CRS, neurologic problems, or any other side effects that are severe.

Do not drive or use heavy or potentially dangerous machinery if you develop dizziness, confusion, tremors, drowsiness, or any other symptoms that impair consciousness until your symptoms go away. These may be symptoms of CRS or neurologic problems.

EPKINLY can also cause other serious side effects, including:
