a clinical study of cht102 in mesothelin positive advanced solid tumors

Conditions: Mesothelin Positive Tumors

Summary: objectives of study：in this study investigators plan to evaluate the safety and efficacy of msln-targeting universal chimeric antigen receptor t-cell immunotherapy(u car-t) in the treatment of msln-positive advanced solid tumors.
