The U.S. Food and Drug Administration approved Breyanzi (lisocabtagene maraleucel), a cell-based gene therapy to treat adult patients with certain types of large B-cell lymphoma who have not responded to, or who have relapsed after, at least two other types of systemic treatment. Breyanzi, a chimeric antigen receptor (CAR) T cell therapy, is the third gene therapy approved by the FDA for certain types of non-Hodgkin lymphoma, including diffuse large B-cell lymphoma (DLBCL). Breyanzi is not indicated for the treatment of patients with primary central nervous system lymphoma.
“Gene and cell therapies have evolved from promising concepts to practical cancer treatment regimens”, said Peter Marks, M.D., Ph.D., director of the FDA’s Center for Biologics Evaluation and Research.
DLBCL is the most common type of non-Hodgkin lymphoma in adults. Non-Hodgkin lymphomas are cancers that begin in certain cells of the immune system and can be either fast-growing (aggressive) or slow-growing. Approximately 77,000 new cases of non-Hodgkin lymphoma are diagnosed in the U.S. each year and DLBCL represents approximately one in three newly diagnosed cases.
Each dose of Breyanzi is a customized treatment created using a patient’s own T-cells, a type of white blood cell, to help fight the lymphoma. The patient’s T-cells are collected and genetically modified to include a new gene that facilitates targeting and killing of the lymphoma cells. Once the cells are modified, they are infused back into the patient.
The safety and efficacy of Breyanzi were established in a multicenter clinical trial of more than 250 adults with refractory or relapsed large B-cell lymphoma. The complete remission rate after treatment with Breyanzi was 54%
