INTERVENTIONAL
Conditions
Summary
The primary aim of this study is to evaluate the efficacy of KRAS mutant antigen specific TCR-T cells in the treatment of patients with advanced solid tumors. The secondary aim is to evaluate the pharmacokinetic/pharmacodynamic characteristics of TCR-T cell therapy in patients with advanced solid tumors and the survival of TCR-T cells. The investigators will evaluate the changes of tumor microenvironment after treatment of advanced solid tumors with KRAS mutant antigen specific TCR-T cells; Evaluating the correlation between cytokines and the occurrence of CRS and neurotoxicity

Interventions
1.Preprocessing strategy: 1. Cyclophosphamide: 300-450mg/m², dissolved in 100ml 0.9% sodium chloride saline, intravenous drip for 60minutes, and 0.4g Mesna injected at 0hour, 4hours and 8 hours after cyclophosphamide,4days and 5 days before TCR-T cell infusion. 2. Fludarabine: 30mg/m² , dissolved in 100ml 0.9% sodium chloride saline, intravenous drip for 30minutes before 3 to 5days before TCR-T cell infusion. 2.Within 3-5 days after pretreatment, subjects will receive a single TCR-T reinfusion with an infusion dose of about 1 × 10⁹~1 × 10¹⁰. 3.Once every 12 hours within 24 hours after TCR-T cell infusion, recombinant human interleukin-2 (injection unit: 500000 units /m², once every 12 hours, subcutaneous injection) will be injected intravenously for 5 days (10 times in total). 4.After 3 months of treatment, If the subject did not occur tumor progression and did not occur adverse events (AEs) of level 3 or higher, a second TCR-T cell reinfusion can be performed.
