BACKGROUND
Chimeric antigen receptor T-cell (CAR-T) therapy is a novel treatment for hematologic malignancies, with 6 FDA agents approved for commercial use. The Veterans Affairs (VA) Tennessee Valley Healthcare System (TVHS) is currently the only VA facility accredited to administer these agents and we are reporting the TVHS experience thus far.
METHODS
TVHS became an authorized treatment center for CAR-T therapy in September 2019 and performed its first CAR-T infusion in December 2019. This is a retrospective electronic chart review of all CAR-T veterans referred to TVHS from the program’s inception, December 1, 2019 through July 31, 2022 to evaluate at least one year of post infusion data. The primary objective is to evaluate the outcomes of veterans who received CAR-T therapy at TVHS including overall response rates (ORR), progression free survival (PFS), and overall survival (OS). Secondary objectives include assessment of toxicities, including rates and maximum grades of cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS).
RESULTS
A total of 41 veterans have received CAR-T infusion at TVHS to date. Twenty-nine of these veterans have at least one year post-CAR-T infusion data and are included in this analysis. The majority of veterans were White (72%), male (93%), and were treated for diffuse large B-cell lymphoma (86%). Twenty-eight percent of veterans were under-represented minorities. Average age was 61 years with 62% being 65 years and older and five (17%) veterans being over the age of 74. Day 30 ORR was 90% (45% complete response [CR]). One-year PFS was 55.2% and 1-year OS was 65.5%. Of the 19 veterans who achieved CR by day 100, 79% remain in CR to date. CRS toxicity was observed in 66% of veterans (0% Grade 3 or higher). ICANS was observed in 27.5% of veterans (24% Grade 3 or higher). Only 5 (26%) veterans required transfer to the intensive care unit for additional monitoring.
CONCLUSIONS
CAR-T therapy has become a wellestablished practice at TVHS and is a safe and effective treatment option for veterans with aggressive lymphoid malignancies. Our outcomes are similar to that seen nationally with better access to under-represented minorities in an aging population.
