Nimotuzumab Combined With Immunotherapy and Chemotherapy in the Treatment of Locally Advanced Head and Neck Squamous Cell Carcinoma

Official title

A Prospective, Randomized, Phase II Study of Nimotuzumab Combined With Immunotherapy and Chemotherapy in the Treatment of Locally Advanced Head and Neck Squamous Cell Carcinoma

Overview

This is a randomized controlled, phase II clinical study designed to explore the efficacy and safety of nimotuzumab combined with immunotherapy and chemotherapy as neoadjuvant treatment for locally advanced head and neck squamous cell carcinoma (LA-HNSCC). The primary endpoint of the study is the 2-year event-free survival (EFS) rate. Enrollment is expected to be completed within 2 years; all patients will be followed up for at least 2 years after the last patient is enrolled.

Interventions

• Drug Nimotuzumab Injection
  Nimotuzumab 400mg，d3，Q3W，for two cycles。
• Drug Tislelizumab
  tislelizumab (or pembrolizumab) 200mg，d1，Q3W，for two cycles。
• Drug Albumin-Bound Paclitaxel /nab-Paclitaxel
  Albumin-bound paclitaxel 180 mg/m² (or docetaxel 75 mg/m²), administered on day 3, every 3 weeks (Q3W);for two cycles。
• Drug Cisplatin (Or Carboplatin)
  Cisplatin 75 mg/m² (carboplatin AUC=5 may be substituted if cisplatin is not tolerated), administered on day 3, every 3 weeks (Q3W).for two cycles。
• Procedure Radical surgery of tumor
  Standard radical surgery of tumor
• Radiation Concurrent chemoradiotherapy
  Concurrent chemoradiotherapy： Radiotherapy: intensity modulated conformal radiotherapy (IMRT) was used with a total dose of 60-66gy (2gy/f, 30-33f). Chemotherapy: Cisplatin 40 mg/m2, QW, 6-7 times in total; Targeting: nimotuzumab 200mg, QW, 6-7 times in total.

Primary outcome measures

• 2-Year Event-Free Survival (EFS) Rate [Time frame: From first study treatment up to 2 years after the last patient randomized.]

Secondary outcome measures (5)

• Major Pathologic Response (MPR) [Time frame: Within 4 weeks after surgery.]
• Pathological Complete Response (pCR) [Time frame: Within 4 weeks after surgery.]
• Objective Response Rate (ORR) [Time frame: After 2 cycles (each cycle is 21 days） of neoadjuvant treatment.]
• 2-Year Overall Survival (OS) Rate [Time frame: From first study treatment up to 2 years after the last patient randomized.]
• Quality of Life (QoL) [Time frame: Baseline（Screening） After neoadjuvant chemotherapy：Study Group（S）Week6 /Control Group（C）NA Post-surgery：S Week 9/C Week 3 After adjuvant radiotherapy（S Week 21/C Week 15） End of treatment（Week 24） Follow-up: Month 6, Month 12, Month 24]

Females: highly effective contraception required during study and for 6 months after last study drug.

Males: highly effective contraception required during study and for 6 months after last study drug.

• Written informed consent obtained prior to any study-specific procedures, and willingness to comply with all study visits and protocol requirements.

Exclusion criteria

• Received PD-1 inhibitors, EGFR monoclonal antibodies, EGFR-TKIs, or anti-angiogenic agents within 4 weeks prior to enrollment.
• Participation in another interventional clinical trial within 30 days prior to screening.
• In the investigator's judgment, the patient cannot tolerate or has contraindications to platinum-based chemotherapy (cisplatin or carboplatin) as specified in the protocol.
• Unresectable disease, poor medical condition for surgery, refusal of surgery for any reason, or excessive tumor burden precluding resection.
• History of other malignancy within the past 5 years (except cured basal cell carcinoma of the skin).
• History of primary immunodeficiency disease.
• Presence of uncontrolled comorbidities, including heart failure, severe pulmonary disease, severe hepatic disease, psychiatric disorders, etc.
