Summary

Claudin 18.2 is a promising therapeutic target overexpressed on the surface of gastric cancer cells. The addition of zolbetuximab, the monoclonal antibody targeting Claudin 18.2 to chemotherapy in two recent Phase 3 studies prolonged survival outcomes, indicating that Claudin 18.2 is a valid target in gastric cancer. Asan Medical Center researchers conducted a study on Claudin 18.2 expression in patients with operable gastric cancer and defined moderate to strong claudin expression in more than 75% of tumor cells as Claudin 18.2 overexpression, which was observed in 46.5% of patients with stage I-III tumors. This suggests that zolbetuximab-based treatment may be possible in patients with LAGC. Therefore, The investigator designed a prospective, multicenter, open-label, Phase Ib/II study to determine the efficacy and safety of zolbetuximab/DOS as neoadjuvant chemotherapy in patients with LAGC.
