Second-line treatment with CAR T-cell therapy for large B-cell lymphoma.

Abstract

The landscape for the treatment of patients with relapsed or refractory (R/R) large B-cell lymphoma (LBCL) has continued to evolve. However, challenges continue to exist, particularly in patients who do not respond to first-line anti-CD20 monoclonal antibody and anthracycline-based therapy or those who experience early relapse. In such patients, the treatment paradigm has changed little in the past 2 decades, with salvage chemotherapy followed by myeloablative chemotherapy and autologous hematopoietic stem cell transplant resulting in historical durable response rates of approximately 40%. Given the success of chimeric antigen receptor (CAR) T-cell therapy in the third- or later-line in the R/R LBCL setting, 3 recent clinical trials (ZUMA-7, BELINDA, and TRANSFORM) have sought to address the clinical need for improved therapies in the high-risk second-line setting for primary R/R disease in the first 12 months. In this review, we analyze these 3 pivotal trials with a focus on clinical trial design, CAR T-cell product attributes, efficacy data, safety data, and patient-reported outcomes when compared with standard of care.
