VIDEO: CAR T cell axi-cel drives B-cell lymphomas into remission

ATLANTA – In the ZUMA-1 trial, more than one-third of patients with refractory large B-cell lymphomas treated with the chimeric antigen receptor (CAR) T-cell product axicabtagene ciloleucel (Yescarta; axi-cel) had durable responses, with some patients having complete responses lasting more than 1 year after a single infusion.

Updated combined phase 1 and 2 results in 108 patients with diffuse large B-cell lymphoma, primary mediastinal B-cell lymphoma, or transformed follicular lymphoma showed an objective response rate of 82% of patients – including 58% showing complete responses – after a median follow-up of 15.4 months.

In a video interview at the annual meeting of the American Society of Hematology, Sattva S. Neelapu, MD, from the University of Texas MD Anderson Cancer Center in Houston discusses the use of CAR T cells directed against the CD19 antigen in patients with relapsed/refractory B-cell lymphomas and describes efforts to improve responses while managing adverse events common to CAR T-cell therapies, notably cytokine release syndrome.

ZUMA-1 is supported by Kite Pharma, which developed axicabtagene ciloleucel, and the Leukemia & Lymphoma Society’s Therapy Acceleration Program. Dr. Neelapu reported receiving advisory board fees from the company.
