Study Summary
This study is a single-center exploratory clinical trial. It is estimated that 9-24 subjects will be enrolled. The "3+3" dose escalation design is adopted. The main purpose is to evaluate the safety of RD133 in the treatment of subjects with relapsed or refractory MSLN-positive solid tumors and explore the Recommend phase II dose of RD133 in the treatment of patients with relapsed/refractory MSLN-positive solid tumors.

The enhanced MSLN-CAR-T cell design of this study is obtained by co-infecting T cells with two lentiviral vectors. One lentiviral vector expresses CD19-CAR and tEGFR molecular safety switch, and the other lentiviral vector expresses MSLN- CAR and dnTGFβRII receptors. dnTGFβRII receptor without intracellular signal is used to resist the inhibition of T cell function by the immune microenvironment of tumor tissue. In addition, for the safety of CAR-T cell application in vivo, tEGFR is used in the CAR design as a molecular safety switch for CAR-T cells.
