Clinical Trial Summary

The purpose of this study is to evaluate the efficacy and safety of Disitamab Vedotin Combined with Cadonilimab in subjects with HER2-expressing locally advanced or metastatic gastric cancer and gastroesophageal junction adenocarcinoma after progression on first-line therapy.

Clinical Trial Description

This is an open-label, randomized, multicenter, Phase II/III Study designed to evaluate safety and efficacy of Disitamab Vedotin Combined with Cadonilimab in subjects with HER2-expressing locally advanced or metastatic gastric cancer and gastroesophageal junction adenocarcinoma after progression on first-line therapy.

This clinical study was divided into two parts, phase II and III.Part I: Phase II study primary objectives of the study are to evaluate the efficacy and safety of Disitamab Vedotin Combined with Cadonilimab versus Disitamab Vedotin versus paclitaxel in subjects with HER2-expressing locally advanced or metastatic gastric cancer and gastroesophageal junction adenocarcinoma after progression on first-line therapy.

Part II: Phase III study primary objectives of the study are to evaluate the efficacy and safety of Disitamab Vedotin Combined with Cadonilimab versus paclitaxel in subjects with HER2-expressing locally advanced or metastatic gastric cancer and gastroesophageal junction adenocarcinoma after progression on first-line therapy.

Tumor assessments, including radiological assessments by CT/MRI scans will be performed at Screening and subsequently every 6 weeks (±7 days) until disease progression, death, the start of new anticancer therapy, or patient's withdrawal of consent (whichever occurs first).

All patients who discontinue treatment will be followed for survival every 3 months until death, lost to follow-up, withdrawal of consent for survival follow-up, or end of study (whichever comes first). ;
