Neoadjuvant EGFR-ADC Combined With Anti-PD-1 Monoclonal Antibody in Resectable Locally Advanced Hypopharyngeal Squamous Cell Carcinoma

Recruiting now · Phase 2

Conditions studied: Hypopharyngeal Squamous Cell Carcinoma

In brief

This clinical trial aims to evaluate the efficacy and safety of Becotatug Vedotin (EGFR-ADC) in combination with Pucotenlimab(Anti-PD-1 Monoclonal Antibody) as neoadjuvant therapy for patients with Resectable Locally Advanced Hypopharyngeal Squamous Cell Carcinoma. The primary objective is the pathological complete response(pCR)rate following neoadjuvant therapy. The secondary objective includes the major pathological response(MPR)rate following neoadjuvant therapy, the objective response rate (ORR), Organ preservation rate, Surgery postponement rate, event-free survival (EFS), overall survival(OS), and safety.
