Brief Summary

This is a single-arm, Multicenter, open-label clinical study aimed at evaluating the safety and efficacy of TCR-T injection in patients with advanced solid tumors induced by KRAS mutations.

Detailed Description

This study is planned to enroll patients with advanced solid tumors who have KRAS G12V or G12D mutations and matching Human Leukocyte Antigen(HLA)-A*11:01 or HLA-C*01:02 subtypes. The study consists of screening period, leukapheresis period, lymphodepletion period, treatment period, observation period and follow-up period. The patients were treated lymphodepletion treatment with cyclophosphamide and fludarabine and than infused TCR-T. All subjects who have received TCR-T injection will be followed for safety and efficacy up to 1 years.
