Outcome Measures

Primary Outcome Measures

1. safety (AE/ irAE/ SAE) [12 months]

   Adverse events, Immue-related adverse，serious adverse event

2. Tolerance(DLT/ MTD/ OBD) [12 months]

   Dose Limiting Toxicity, Maximum Tolerated Dose, Optimal Biological Dose

Secondary Outcome Measures

1. Progression-free Survival (PFS) [12 months]

   The time between the NeoAg/aeTSA CTL initiation and the onset of tumor progress or death from any cause

2. Overall Survival (OS) [12 months]

   From the beginning of NeoAg/aeTSA CTL initiation to the time of death from any cause
