Additionally, infusion led to the depletion of CD4+ Treg cells and expansion of CD3+CD8+ T cells and NK cells. These results suggest that CD4-IL15/IL15sushi CAR T cells may be a safe and effective treatment for patients with relapsed or refractory T-cell lymphomas, where new treatment options are needed.
An alemtuzumab safety switch has also been established to ensure the elimination of CAR T cells following tumor eradication...Patient received a total dose of 3x10^6 /kg single dose CAR T cells, following which fluconazole and valacyclovir were administrated for infection prophylaxis...Conclusion Our first-in-human clinical trial demonstrates promising efficacy of CD4 CAR T cell therapy in treating patients with refractory Sezary syndrome. cCAR is able to eradicate leukemia blasts, exerting a profound tumor killing effect that is superior to traditional chemotherapies.
