phase ii study of neoadjuvant cetuximab and cemiplimab in patients undergoing surgery for hnscc

Conditions: Head and Neck Squamous Cell Carcinoma

Summary: the purpose of the study is to determine if cemiplimab in combination with cetuximab given before their surgery are beneficial and safe in participants with head and neck squamous cell carcinoma (hnscc).
