Phase 2

Recruiting

• Conditions: Gastric Cancer
• Interventions: Drug: Carelizumab Combined With Irinotecan and Apatinib

• Registration Number: NCT04934618
• Lead Sponsor: Nanfang Hospital, Southern Medical University

Brief Summary

The purpose of this study was to evaluate the overall survival time (OS), objective remission rate（ORR）, progression-free survival time（PFS）, disease control rate（DCR）of Carelizumab combined with irinotecan and apatinib for the second-line treatment of locally advanced unresectable, recurrent or metastatic adenocarcinoma of stomach and gastroesophageal junction. At the same time, the safety and tolerance of the scheme were preliminarily evaluated.
