Phase 1

• Conditions: Colorectal Cancer Recurrent
• Interventions: Drug: Camrelizumab; Drug: Apatinib

• Registration Number: NCT04067986
• Lead Sponsor: Zhongshan Hospital Xiamen University

Brief Summary

The efficacy and safety of the use of Camrelizumab combined with Apatinib

Detailed Description

To evaluate the clinical efficacy and safety of Camrelizumab combined with Apatinib in the treatment of patients with advanced gastric cancer and colorectal cancer.

The 62 patients were enrolled in a 2-week regimen with 200mg Camrelizumab given intravenously every two weeks and 250mg apatinib mesylate every 4 weeks for a treatment cycle until progressive or intolerable，then the objective remission rate(ORR) was calculated.
