A Phase I Clinical Study of Cord Blood-Derived CAR-NK Cells Targeting Claudin18.2 in the Treatment of Advanced Gastric Cancer and Advanced Pancreatic Cancer

Trial ID: NCT06464965

Interventional - Phase 1 - Completed

Main Objective: To study the maximum tolerated dose (MTD) and dose-dependent toxicity (DLT) of cord blood-derived CAR-NK cells (CB CAR-NK182) targeting Claudin18.2 in patients with advanced gastric cancer and advanced pancreatic cancer. Secondary Objective: To evaluate the efficacy of CB CAR-NK182 in patients with advanced gastric cancer and advanced pancreatic cancer: overall objective tumor response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), duration of response (DOR), etc. To evaluate the CAR-NK amplification and persistence of CB CAR-NK182 in the blood of patients with advanced gastric cancer and advanced pancreatic cancer;

Conditions

• Gastric Cancer
• Pancreas Adenocarcinoma

Interventions

• CB CAR-NK18.2
• Cyclophosphamide
• Fludarabine
