The U.S. Food and Drug Administration (FDA) has approved a new indication for Breyanzi (Lisocabtagene maraleucel) as the first Chimeric Antigen Receptor (CAR) T-cell therapy in the U.S. for treatment of adults with marginal zone lymphoma (MZL) who have failed treatment with or relapsed after two or more prior lines of therapy.
Breyanzi is a Chimeric Antigen Receptor (CAR) T-cell therapy that genetically engineers a patient's own T-cells to target and kill cancers.
The "approval represents a major advancement in precision medicine, essentially turning the patient's immune system into a more effective tool to treat MZL," Vinay Prasad, M.D., M.P.H., Chief Medical and Scientific Officer and Director of FDA's
Center for Biologics Evaluation and Research.
"The FDA continues to optimize its regulatory authority to expand treatment options in the fight against cancer."
Marginal zone lymphoma (MZL) is a rare slow-growing cancer of the
lymphomatic system. It presents about 7 percent of all
B-cell non-Hodgkin lymphoma, with approximately 7,460 new cases occurring every year in the U.S. population, said FDA.
Patients with MZL who failed treatment or relapsed following treatment with upfront therapy have decreased survival.
"In granting approval, FDA took into consideration the high and durable response rate following a one-time treatment in patients with MZL, almost half of whom had either progression within two years of diagnosis or had refractory disease."
The safety and effectiveness of Breyanzi were evaluated in an open-label, multi-center, single-arm trial in adults with relapsed or refractory MZL who had received at least two or more lines of systemic therapy or who relapsed after hematopoietic stem cell transplant (HSCT).
Study participants underwent
leukapheresis, a process to collect a patient's own immune cells to manufacture Breyanzi.
Patients received a single dose of Breyanzi two to seven days following the completion of preparatory chemotherapy to deplete recipient's
lymphocytes, a type of white blood cells, said FDA.
Among the 77 patients who underwent leukapheresis, 66 patients received the study specified single infusion of Breyanzi, of which 99.5 percent of patients experienced a response to treatment and 62.1 percent of patients had complete response without signs of marginal zone lymphoma on imaging scans.
The responses were durable after a median follow up of 21.6 months.
The most common adverse reactions cytomine release syndrome (CRS), diarrhea, fatigue, musculoskeletal pain, and headache.
The FDA granted traditional approval of Breyanzi to Juno Therapeutics, Inc.
