• Status: Recruiting
• Trial end date: 2022-12-31
• Target enrollment: 0
• Participant gender: All

Summary

This study was designed to evaluate the efficacy and safety of camrelizumab in combination with SOX and/or apatinib in the treatment of locally advanced gastric cancer or gastroesophageal junction adenocarcinoma.The primary endpoint was pathologic complete response (PCR).In addition, secondary efficacy endpoints include R0 resection rate, objective response rate (ORR), and 1-year progression-free survival rate (PFSR) . They were set to demonstrate the therapeutic benefit of camrelizumab combined with SOX in patients 。
