TCR-T Cells Injection（GB3010 Cells Injection）

Experimental group

Description:

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.
