The CD7 CAR construct possesses a "safety switch" (RTX) to enable rapid depletion of the CAR T treatment with administration of rituximab. However, this study supports the importance of thorough tumor characterization and the potential use of CD7-RTX CAR T cells to treat a variety of malignancies expressing CD7. Future clinical trials are required to characterize the safety and efficacy of CD7-RTX CAR T cells.
