Treatment for advanced pancreatic and gastric cancers using Claudin18.2 CAR-T cells

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial investigates the safety and efficacy of Claudin18.2 CAR-T cell therapy in patients with advanced pancreatic and gastric cancers. Claudin18.2 is a protein that is highly expressed in these types of tumors, and preclinical studies suggest that targeting it with CAR-T cells may improve remission rates. Participants will receive Claudin18.2 CAR-T cells after failing standard treatment options. The study aims to provide a new therapeutic approach for patients with non-resectable, late-stage cancers.
