This is a Phase 1, open label, multicenter study to evaluate Claudin 18.2-targeting CAR-T cells (LB1908) in adult subjects with unresectable, locally advanced or metastatic gastric, GEJ, esophageal, or pancreatic adenocarcinoma. Patients will be confirmed to have sufficient expression of Claudin 18.2 as part of a prescreening. The study comprises a dose-escalation component (Part A) and a dose-expansion component (Part B). In part A, patients with gastric, GEJ, or esophageal adenocarcinoma will be treated with LB1908 at protocol-defined dose level, with escalation to higher doses in subsequent patients guided by evaluation of protocol-defined dose limiting toxicities (DLTs). Part A will identify the recommended dose for expansion (RDE) to be tested in part B in two cohorts: a gastric, GEJ and esophageal adenocarcinoma cohort as well as a pancreatic adenocarcinoma cohort. Part B will aim to identify the recommended dose for phase 2 (RP2D).
This is a Phase 1, Open-Label, Dose Escalation and Expansion, Multicenter Study of Claudin 18.2-Targeted Chimeric Antigen Receptor T-cells in Subjects with Unresectable, Locally Advanced, or Metastatic Gastric, Gastroesophageal Junction (GEJ), Esophageal, or Pancreatic Adenocarcinoma
