Arms & Interventions
TCR-T Cells Injection（GB3010 Cells Injection）
This study was designed to evaluate the safety, tolerability, efficacy, and pharmacokinetics of TCRT cell injection (GB3010) in patients with advanced pancreatic cancer by intravenous injection. The target population is patients with advanced pancreatic cancer who lack effective treatment methods, so that the benefits of patients participating in clinical trials will outweigh the risks.
Intervention: TCR-T Cells Injection（GB3010 Cells Injection）
Outcomes
Primary Outcomes
Evaluate the Incidence of Treatment Related Adverse Events of TCRT cells in patients with advanced pancreatic cancer
Time Frame: 2years
collect adverse events (AE), serious adverse events (SAE), adverse events of special interest (AESI), and laboratory abnormalities (type, frequency, and severity)
Characterize the Peak of Peripheral Blood Concentration and Area under the Peripheral Blood concentration versus time curve of TCRT cells and observe their proliferation and persistence in body
Time Frame: 2years
After infusion of neoantigen-specific TCRT cells, collect peak (Cmax) of neoantigen-specific TCRT cells in blood and tumor tissue, time to peak (number of days to peakTCRT cells after infusion), Tmax) and AUC0-28 (area under the curve plotted against visit time by the number of neoantigen-specific TCRT cells in peripheral blood from day 0 to 28). "If possible, AUC0-inf, terminal phase elimination rate constant (λz), elimination half-life (t1/2) will be evaluated."
Secondary Outcomes
- Correlation of the pharmacokinetic profile of TCRT cells with the Incidence of CRS and ICANS events(2years)
- Evaluate tumor size (mm) , tumor biomarker CA19-9 (U/ml), ORR/DCR/PFS and OS of patients with advanced pancreatic cancer(2years)
