TCR-T Cells in the Treatment of Advanced Pancreatic Cancer

Brief summary public domain (ClinicalTrials.gov)

To investigate the safety, tolerability, efficacy and pharmacokinetics of TCR-T cells in the treatment of advanced pancreatic cancer

Detailed description public domain (ClinicalTrials.gov)

The aim of this clinical trial is to investigate the safety, tolerability, efficacy and pharmacokinetics of TCR-T cell therapy in patients with advanced pancreatic cancer by intravenous injection, in order to explore an effective cellular immunotherapy method for the treatment of advanced pancreatic cancer

Intervention public domain (ClinicalTrials.gov)

Drug: TCR-T Cells Injection（GB3010 Cells Injection）. The TCRT cells used in this clinical trial were derived from the patient's autologous peripheral-blood T cells and were genetically transduced to express a T-cell Receptor that recognizes the RAS/TP53.Patients were sequentially enrolled into 3 dose escalation groups(dose level 1-3) :5×10^8±20%,5×10^9±20%,5×10^10±20%.

Arm public domain (ClinicalTrials.gov)

TCR-T Cells Injection（GB3010 Cells Injection） (experimental): 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.
