Official title
A Phase 2 Study in First Line Metastatic or Unresectable, Recurrent Head and Neck Squamous Cell Carcinoma to Evaluate Intratumoral MK-1454 in Combination With IV Pembrolizumab vs IV Pembrolizumab Monotherapy
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to assess the efficacy and safety of intratumoral (IT) ulevostinag PLUS pembrolizumab (MK-3475) compared to pembrolizumab alone as a first line treatment of adults with metastatic or unresectable, recurrent head and neck squamous cell carcinoma (HNSCC). The primary study hypotheses are that IT ulevostinag in combination with pembrolizumab results in a superior Objective Response Rate (ORR), per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1), compared to pembrolizumab alone: 1. In participants with a tumor that has a programmed cell death-ligand 1 (PD-L1) Combined Positive Scoring (CPS) ≥ 1, and 2. In participants with a tumor that has a PD-L1 CPS ≥ 20.
