A Single-center Phase II Study to Investigate the Immune Maintenance Therapy Pattern in Patients With Locally Advanced Head and Neck Squamous Cell Carcinoma Who Have Achieved MPR After Neoadjuvant Immunotherapy Combined With Chemotherapy

FERRY

Head and neck cancer is the malignant tumor with the highest morbidity and mortality, of which 60% present with locally advanced disease at initial diagnosis, and the 5-year survival rate of standard treatment is less than 30%. Standard of care (SOC) including adjuvant and neoadjuvant therapy can provides only about 5-10% clinical benefit. According to the available data on the application of immunotherapy as adjuvant therapy in operable patients, adjuvant immunotherapy is safe and feasible, with a significant trend of benefit. Based on the above positive and meaningful clinical needs and scientific basis, it is very necessary to carry out clinical trials of adjuvant immunotherapy. The primary objective of this study is to evaluate the efficacy and safety of immune maintenance therapy in patients with locally advanced head and neck squamous cell carcinoma who achieve MPR after neoadjuvant immunotherapy combined with chemotherapy.
