Brief summary
CMP-001-007 is a Phase 2 study of CMP-001 intratumoral (IT) and pembrolizumab intravenous (IV) administered to participants with head and neck squamous cell carcinoma (HNSCC) who have not been previously treated with a programmed cell death protein 1 (PD-1) blocking antibody. The primary objective of the study is to determine the Investigator-assessed confirmed objective response with CMP-001 in combination with pembrolizumab in subjects with head and neck squamous cell carcinoma (HNSCC) The secondary objectives are to: * To evaluate the safety and tolerability of CMP-001 administered by intratumoral (IT) injection in combination with pembrolizumab in subjects with HNSCC * To evaluate the efficacy of CMP-001 in combination with pembrolizumab in subjects with HNSCC * To evaluate the effect of human papillomavirus (HPV) infection and programmed death-ligand 1 (PD-L1) expressions on the efficacy of CMP-001 in combination with pembrolizumab Participants will continue to receive treatment of CMP-001 and pembrolizumab according to the treatment schedule until a reason for treatment discontinuation is reached.

Interventions
Subjects will receive CMP-001 10mg weekly for 2 doses after which CMP-001 will be administered every 3 weeks. The first dose of CMP-001 may be administered subcutaneously (SC) or Intratumorally (IT) at the discretion of Investigator. All subsequent doses will be injected intratumorally every 3 weeks (Q3W).
Pembrolizumab 200 mg IV is administered Q3W.
