Brief Summary

A Randomized, Phase II Study of MRG003 in Combination With Pucotenlimab Injection ± Cisplatin in Patients With Locally Advanced EGFR-positive Head and Neck Squamous Cell Carcinoma. This proposed study will evaluate the efficacy and safety of preoperative administration of MRG003 in Combination With Pucotenlimab Injection ± Cisplatin in HNSCC who are eligible for resection.

Detailed Description
