Clinical Trial Summary

This is an open-labeled, single-armed and prospective study, patients with advanced malignant solid tumors will be given with SL22P autologous CAR - T/CAR-TILs cells. The aim of the study is to evaluate the safety and efficacy of SL22P CAR-T cells, including the adverse reaction, pharmacokinetics, and the outcomes of patients.

Clinical Trial Description

SL22P is a proprietary product of Senlang Biotechnology. The T cells may be isolated from the peripheral blood or from the tumor tissue. The CAR-T/CAR-TILs cells contains a anti-CD22 CAR structure and also carries a scFv fragment of anti-PD-L1 monoclonal antibody. After autologous SL22P CAR-T/CAR-TILs cells were transplanted back into patients, CAR-T would target CD22+B cells in the blood. This will promote the activation and amplification of CAR+ cells, and secrete anti-PD-L1 scFv outside the cells to regulate the immunity and enhance anti-tumor activity. The CAR-TILs may reduce the severity of the adverse reactions than conventional TILs, which result from the combination of high dose IL-2 infusion. ;
