In Brief

A Phase 2 clinical trial evaluating Ulevostinag and Pembrolizumab for Head and Neck Squamous Cell Carcinoma (HNSCC). Completed, enrolled 18 participants across 34 sites in 10 countries.

Detailed Summary

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.
