SAN DIEGO – Aggressive, refractory non-Hodgkin lymphomas responded to anti-CD19 chimeric antigen receptor T cells in ZUMA-1, the first multicenter trial of the cellular immunotherapy, based on early data reported at the annual meeting of the American Society of Hematology.
In an interim analysis of 51 patients with diffuse large B-cell lymphomas, 47% had complete remissions and 29% had partial remissions. But the remission rate declined to 33% complete remissions and 6% partial remissions after 3 months.
There have really been no new treatments in the last 20 years for patients with non-Hodgkin lymphoma that does not respond to chemotherapy or recurs after autologous stem cell transplant. With median overall survival of 6 months, and about 8% complete remissions with existing therapies, CAR T cells might be a solution for these patients, said ZUMA-1 investigator, of the University of Texas MD Anderson Cancer Center in Houston.
Inat the meeting, Dr. Neelapu discussed initial results in the real-world setting of 22 participating centers, most of which had no previous experience with CAR T-cell therapy. With an efficient production and logistics plan, 91% of 110 patients were able to receive the investigational product, known as KTE-C19.
ZUMA-1 is funded by Kite, which makes KTE-C19, and the Leukemia & Lymphoma Society Therapy Acceleration Program. Dr. Neelapu receives research support from and is an advisor to Kite.
