XW-LTH-03

This is a single-arm, open-label clinical study evaluating the safety and preliminary efficacy of a novel hypoxia-inducible, bispecific CD73/AXL-targeting CAR-T cell product, XW-LTH-03, in patients with stage IV gastric cancer (GC). The primary objective is to assess the safety and tolerability of XW-LTH-03 infusions. Secondary objectives include the evaluation of its antitumor efficacy and the characterization of its pharmacokinetic profile by measuring the in vivo expansion and persistence of the CAR-T cells. Exploratory analyses aim to identify potential biomarkers associated with clinical response and toxicity, as well as to investigate the cellular and molecular mechanisms underlying potential treatment resistance.
