It will also learn about the safety of CBG131 and find the best dose to use.\n\nThe main questions it aims to answer are:\n\nIs CBG131 safe, and what medical problems do participants have when receiving it? Does CBG131 shrink tumors in participants with CLDN18.2-positive cancers? How long do the CAR-T cells stay and work in the body? Researchers will test different doses of CBG131 to see which dose is safest and most effective. This is an early-stage trial, so there is no placebo group-everyone who joins will receive the actual treatment.\n\nParticipants will:\n\nHave their blood cells collected through a procedure called leukapheresis (so the CAR-T cells can be made).\n\nReceive chemotherapy for 3 days to prepare their body for the CAR-T cells Get a single infusion of CBG131 CAR-T cells through an IV. Visit the clinic frequently for the first month, then regularly for 2 years for checkups, blood tests, and tumor assessments.\n\nKeep track of their symptoms and any side effects they experience.",[66],"Advanced Gastric and Pancreatic Cancer","NOT_YET_RECRUITING","2026-02-01",{"date":70,"type":71},"2026-02-06","ACTUAL",{"date":73,"type":60},"2026-09-30",{"date":75,"type":60},"2030-01-31",{"name":5,"class":6},1]
