Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Parallel Assignment
    • Primary Purpose: Other
    • Masking: None (Open Label)
  • Study Primary Completion Date: October 31, 2020

Detailed Description

Patients in the camrelizumab group were treated with camrelizumab with the dose of 200mg on day 1, repeated every 21 days.Patients in the combination group were treated with MWA in the primary tumor followed by camrelizumab with the dose of 200mg on day 1, repeated every 21 days.

The primary end point is overall survival. The second end points include progression free survival, objective response rate and safety.


  • Drug: Camrelizumab
    • Patients will be treated with camrelizumab alone.
  • Other: Camrelizumab plus microwave ablation
    • In the group, microwave ablation will be administrated to the primary tumors, followed by camrelizumab.

Arms, Groups and Cohorts

  • Active Comparator: Microwave ablation plus camrelizumab group
    • Patients in the group are treated with Microwave ablation in the primary tumor, followed by camrelizumab.
  • Placebo Comparator: Camrelizumab group
    • Patients in the group are treated with camrelizumab alone.
