Description

Inclusion Criteria:

• Patients voluntarily joined the study, signed the informed consent, and had good compliance;
• Patients with 18 Years to 75 Years(at the time of signing the informed consent); Eastern Cooperative Oncology Group Performance Status (ECOG-PS) score: 0-1;
• Patients with untreated head and neck squamous cell carcinoma who were pathologically confirmed and determined to be suitable for surgical treatment were classified as stage III, IVa according to AJCC (8th Edition), including oral, oropharyngeal, hypopharyngeal, and laryngeal cancers
• Female patients of reproductive age should agree that birth control (such as intrauterine device, birth control pills, or condoms) must be used during the study period and for six months after completion; Having a negative serum pregnancy test within 7 days prior to study enrollment, and must be non-lactating; Male patients should agree to use contraception during the study period and for six months after the end of the study.

Exclusion Criteria:

• Patients who have previously used PD-1/PD-L1/CTLA-4 antibody therapy;
• Patients who require systemic treatment with corticosteroids (> 10mg daily prednisone equivalent) or other immunosuppressive drugs within 14 days prior to administration or during treatmentIn the absence of active autoimmune disease, inhaled or topical steroids and adrenocortical hormone at doses >10mg/ day equivalent to prednisone and adrenocortical hormone replacement at therapeutic doses not exceeding 10mg/ day prednisone are permitted;

Participant Group / Arm

Intervention / Treatment

Experimental: Penpulimab combined with cisplatin and albumin-paclitaxel neoadjuvant therapy; Penpulimab injection combined with cis-platinum and albumin-bound paclitaxel before surgery, 21 days as a treatment cycle. Adjuvant therapy was started within 6 weeks after surgery：Patients who achieved MPR after surgery were randomized 1:1 with standard adjuvant therapy(RT alone or combined with cisplatin) and Alternative adjuvant therapy(RT alone or combined with Penpulimab). Non-MPR patients receive standard adjuvant therapy

Drug: Penpulimab injection; Penpulimab is a human immunoglobulin G1(IgG1) monoclonal antibody (mAb) directly programmed cell death-1 (PD-1). AK105 can effectively prevent human PD-1 binds to programmed cell death-1 ligand 1(PD-L1) and programmed cell death-1 ligand 2(PD-L2)； 200mg,D1, IV(21 days/cycle).; Drug: cisplatin; Cisplatin :75mg/m2, D1, IV(21 days/cycle); Drug: albumin-paclitaxel; albumin-paclitaxel :260mg/m2,IVgtt,D1(21 days/cycle)

Overall Response Rate (ORR)	The proportion of subjects who achieves a best overall response of CR or PR.	Baseline up to 3 years.
Local recurrence-free survival at 2years(LRFS at 2 years)	The proportion of subjects local recurrence-free survival at 2years	Baseline up to 2 years.
distant metastasis-free survival at 2 years(DMFS at 2 years)	The proportion of subjects distant metastasis-free survival at 2years	Baseline up to 2 years.
OS at 2 years	The overall survival time refers to the time from initiating inductive therapy to death due to any cause.	Baseline up to 2 years.
pathologic complete response(pCR)	Pathological examination showed the presence of 0% active tumor in the tissue specimen	One year
