Study Summary

This is a multi-center, open-label, Phase 0 substudy designed to evaluate the ability of pembrolizumab, alone and in combination with MK-0482 or MK-4830, to elicit pharmacodynamic changes suggestive of antitumor immune activation within the native tumor microenvironment (TME) following intratumoral microdosing via the CIVO device in patients with surface accessible Head and Neck Squamous Cell Carcinoma (HNSCC) or Soft Tissue Sarcoma (STS) lesion(s) who are scheduled for tumor and/or regional node dissection as part of their standard treatment.

Primary Outcome

Quantification of biomarker-positive and biomarker-negative cells will be performed within the tumor microenvironment around injection sites in resected patient samples by IHC, ISH, or spatial biology platforms. An aggregate analysis of this quantification may be done across patient samples in each substudy to evaluate trends in tumor response. The biomarkers evaluated may include, but are not limited to, markers associated with macrophage polarization states (e.g., CD163), markers of infiltrati
