Study Summary

Single-arm phase 2 study to examine pembrolizumab and concurrent radiation to induce an abscopal effect in patients with previously treated carcinoma of unknown primary (CUP16-268)

Primary Outcome

Evaluate the abscopal response rate in Carcinoma of Unknown Primary (CUP) patients treated with the combination of pembrolizumab plus radiotherapy. Best abscopal response is defined as the frequency of patients whose best responding abscopal lesion demonstrates at least a 30% decrease in its longest diameter from baseline (Golden et al., 2015).

Interventions

  • DRUG Pembrolizumab
  • RADIATION External Beam Radiation Therapy
