Filter by:The goal of this clinical trial is to study how approaches for manufacturing chimeric antigen receptor (CAR)-modified T (CAR-T) cells affect their in vivo persistence and therapeutic efficacy against B lymphoma. Recently, cancer immunotherapy, treatments aiming to arm patients with immunity specifically against cancer cells, has emerged as a promising therapeutic strategy. Among the many emerging immunotherapeutic approaches, clinical trials utilizing CARs against B cell malignancies have demonstrated remarkable potential. CARs combine the variable region of an antibody with T-cell signaling moieties to confer T-cell activation with the targeting specificity of an antibody. Thus, CARs are not MHC-restricted so they are not vulnerable to MHC down regulation by tumors. However, defined by the activation and contraction program of their mother cells, the persistency and function of CAR-T cells are also restricted by the protocol of manufacturing. Previous clinical studies largely utilized interleukin-2 (IL-2) for the ex vivo expansion of CAR-T cells, which preferentially generate CAR-T cells with characteristics of terminally differentiated effector cells. Our preliminary data indicated that two common gamma chain cytokines, IL-7 and IL-15, can help to selectively expand CAR-T cells with various memory phenotypes. CAR-T Cells prepared under this condition resulted in improved therapeutic efficacy in preclinical animal models. This clinical investigation is to test a hypothesis whether IL-7/IL-15-programmed anti-CD19 CAR-T cells persist longer in lymphoma patients after infusion and whether the persistency of CAR-T cells can lead to improved anti-lymphoma efficacy.
Many trials that patients with advanced or recurrent indolent lymphoma managed with very low-dose (4Gy) limited-field RT (LD-IFRT) have shown that high response rates and durable remission can be achieved. However, the results of two phase III trials have failed to demonstrate the lasting response rate (RR) with LD-IFRT versus in other approaches. Histology, bulky tumor (>5 cm), higher number of prior chemotherapy regimens, adoption of rituximab, and age＞65 years have been shown to significantly influence response rates of LD-IFRT. The objectives of this trial investigate the efficacy of palliative low-dose involved-field radiation therapy in patients lower than 65 years of age with recurrent advanced follicular lymphoma.
