Summary

The goal of this type of study: single center exploratory clinical trial is to evaluate the efficacy and safety of Toripalimab combined with AP-induced chemotherapy followed by concurrent chemoradiotherapy and Toripalimab-maintenance therapy sequentially in patients with non-metastatic IVB hypopharyngeal cancer. The main question[s] it aims to answer are: • [main objectives: to evaluate the objective remission rate (ORR), progression-free survival (PFS) and safety of PD-1 inhibitor Toripalimab combined with induction chemotherapy (cisplatin / nedaplatin + albumin paclitaxel) in patients with locally advanced head and neck squamous cell carcinoma according to RECISTv1.1.] • [Secondary objectives: 1-year, 2-year, 3-year progression-free survival rate (PFS); 1-year, 2-year, 3-year overall survival rate (OS); overall survival time (OS); tumor regression time; quality of life was evaluated by ECOG physical status and EQ-5D-5L assessment. ] [Exploratory Objective: to explore the relationship between the biomarkers in tumor tissue and / or blood, including PD-L1 (CPS/TPS), HPV (P16), PD-1, TMB, EGFR, CD3, CD4, CD8, TP53, MSI-H and the efficacy of immunotherapy, and the relationship between MDM2/MDM4, EGFR, chromosome 11q13 interval (CCND1/FGF19/FGF3/FGF4) and immune hyperprogression] Participants will [be treated with Toripalimab injection (240mg/, once every 3 weeks) combined with cisplatin / nedaplatin (40mg) and albumin paclitaxel (230mg/m2, once every 3 weeks). The efficacy was evaluated within 1 week after induction therapy. In the phase of simultaneous radiotherapy, albumin paclitaxel (230mg/m2, once every 3 weeks, D1/D21/D43) was used. One month after the end of synchronous radiotherapy and chemotherapy, the efficacy was evaluated. After evaluation, all patients entered the next stage of immune maintenance therapy. During the maintenance phase, Toripalimabv injection (240mg/, once every 3 weeks) was given for 6 months or until the disease progressed, the toxicity was intolerable, the subjects asked to withdraw voluntarily, and the researchers judged that the subjects needed to withdraw from the study. The patients were treated with spiral tomographic radiotherapy (TOMO) or intensity modulated radiotherapy (IMRT).. These patients were given Nimotuzumab injection at the same time during simultaneous radiotherapy and chemotherapy.
