Brief Summary

This is a single-center, single-arm, phase II clinical study to evaluate the efficacy and safety of PD-1 inhibitor combined with cetuximab in neoadjuvant therapy for locally advanced HNSCC.

Detailed Description

At present, the standard treatment for patients with operable locally advanced head and neck squamous cell carcinoma (HNSCC) is adjuvant radiotherapy with or without platinum-based synchronous chemotherapy after operation. However, the risk of recurrence, metastasis and death remains high in this population with this intense combination treatment regimen. Both EGFR monoclonal antibody and PD-1 inhibitors have proven the effect in advanced HNSCC. At the same time, cetuximab and PD-1 inhibitors have been reported to have a synergistic effect that may improve patient survival. This study aims to explore the efficacy and safety of PD-1 inhibitor combined with cetuximab in neoadjuvant therapy for locally advanced HNSCC.

Conditions

Head and Neck Squamous Cell Carcinoma; Neoadjuvant Therapy

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

Neoadjuvant therapy+Surgery+Adjuvant therapy+Consolidation therapy

Participants receive totally 3 cycles of neoadjuvant therapy (Toripalimab+cetuximab), then radical treatment(surgery). After surgery, Participants receive radiotherapy or chemoradiotherapy according to the pathological results of the operation. Then, participants receive consolidation therapy of Toripalimab.

Group Type: OTHER

3cycles (Toripalimab + cetuximab)

Intervention Type: DRUG

Toripalimab by intravenous (IV) infusion every 3 weeks (Q3W), 3 preoperative and 17 consolidated doses.

The preoperative starting dose of cetuximab is 400 mg/m^2 by IV infusion over 120 minutes for 1 week, subsequently followed by 250 mg/m^2 IV infusion over 60 minutes, from week 2 to 9.

Surgery

Intervention Type: PROCEDURE

After neoadjuvant therapy, patients would accept surgery within 11-13 weeks.

Radiotherapy or chemoradiotherapy

Intervention Type: RADIATION

Adjuvant radiotherapy was given 4 weeks after surgery. Patients with positive intraoperative pathological margins/extra lymph node envelope invasion are treated with an additional cisplatin synchronous chemotherapy.
