ExperimentalExperimental Induction therapy include Iparomlimab and Tuvonralimab injection combined with hypofractionated radiotherapy (5 Gy × 3) for two cycles, followed by sequential concurrent chemoradiotherapy (50 Gy/25 fractions with two cycles of cisplatin). After completing chemoradiotherapy, patients receive maintenance Iparomlimab and Tuvonralimab injection for at least six months. | Iparomlimab and Tuvonralimab injection Induction therapy include Iparomlimab and Tuvonralimab injection combined with hypofractionated radiotherapy (5 Gy × 3) for two cycles, followed by sequential concurrent chemoradiotherapy (50 Gy/25 fractions with two cycles of cisplatin).

|---|---|---|
Objective Response Rate (ORR) | Objective Response Rate (ORR) refers to the proportion of patients who achieve a measurable reduction in tumor burden, specifically those who experience a complete response (CR) or partial response (PR) according to standardized criteria (such as RECIST). | From enrollment to the first documented tumor response assessment |
Progression-free survival(PFS) | Progression-free survival is the length of time from the start of treatment (or from randomization/enrollment) until the disease progresses or the patient dies from any cause, whichever occurs first. | From the date of enrollment until the date of first documented disease progression or death from any cause, whichever occurs first, assessed up to 1 year. |
Distant Metastasis-Free Survival (DMFS) | Distant Metastasis-Free Survival (DMFS) is the length of time from the start of treatment (or from diagnosis/enrollment) until the first occurrence of distant metastasis or death from any cause, whichever happens first. | From the date of enrollment until the date of first documented distant metastasis or death from any cause, whichever occurs first, assessed up to 1 year. |
Overall Survival(OS) | Overall Survival(OS) is defined as the period from the date of first treatment administration to the date of death due to any cause. | From the date of enrollment until the date of death due to any cause. |
Adverse events. | The incidence, type, and severity of adverse events (AEs), serious AEs, and immune-related AEs (irAEs) were assessed in accordance with the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE version 5.0). | From enrollment to the end of treatment at 3 years. |
Signed a written informed consent form and understands and agrees to comply with the study requirements and visit schedule.
Male or female subjects aged ≥18 and ≤75 years at the time of signing informed consent.
Eastern Cooperative Oncology Group (ECOG) performance status (PS) score of 0 or 1.
Histologically or cytologically confirmed stage III-IVB head and neck squamous cell carcinoma as assessed by the investigator.
No prior systemic therapy for head and neck squamous cell carcinoma (including chemotherapy, EGFR monoclonal antibodies, anti-PD-1 or anti-PD-L1 antibodies, anti-CTLA-4 antibodies, or other immune checkpoint inhibitors).
At least one measurable target lesion per RECIST v1.1 criteria.
Estimated life expectancy ≥12 weeks.
Adequate bone marrow and organ function (without receiving any cellular products, blood components, colony-stimulating factors, or cytokine therapy within 14 days prior to laboratory testing):
- Hematology: ANC ≥1.5 × 10⁹/L or within normal range; platelet count ≥100 × 10⁹/L; hemoglobin ≥90 g/L.
- Liver function: Total bilirubin ≤1.5 × ULN; for Gilbert's syndrome, TBIL ≤3 × ULN; AST and ALT ≤2.5 × ULN in patients without liver metastasis, or ≤5 × ULN in those with liver metastasis; albumin ≥28 g/L.
- Renal function: Serum creatinine ≤1.5 × ULN, or creatinine clearance (CCR) ≥60 mL/min (calculated via Cockcroft-Gault formula or measured via 24-hour urine collection); urine dipstick protein <2+. For subjects with baseline ≥2+ proteinuria, a 24-hour urine test must show <1 g of protein (if both tests are done, the 24-hour result will determine eligibility).
- Coagulation: International normalized ratio (INR) ≤1.5; activated partial thromboplastin time (APTT) ≤1.5 × ULN.
Subjects who are infertile or agree to use at least one highly effective contraceptive method during the study (starting 14 days before screening or first dose, whichever occurs earlier, and continuing until 180 days after the last dose of study drug).
History of allergy to any component of anti-PD-1/CTLA-4 antibodies or cisplatin.
History or presence of another malignancy (except those cured and without recurrence for more than 5 years, including basal cell carcinoma, carcinoma in situ of the cervix, and papillary thyroid carcinoma).
Uncontrolled cardiac symptoms or diseases, including:
- New York Heart Association (NYHA) class II or higher heart failure.
- Unstable angina.
- Myocardial infarction within the past year.
- Clinically significant supraventricular or ventricular arrhythmias requiring clinical intervention.

- Previous treatment with anti-PD-1, anti-PD-L1, or anti-CTLA-4 antibodies.
- Use of any investigational drug within 4 weeks prior to the first dose of study drug.
- Concurrent participation in another clinical trial, unless it is an observational (non-interventional) study.
- Requirement for systemic corticosteroid therapy (≥10 mg prednisone or equivalent/day) or other immunosuppressive drugs within 2 weeks prior to the first dose of study drug, except for topical or inhaled steroids, or prophylaxis for nausea, vomiting, or allergic reactions. Other special circumstances should be discussed with the investigator. In the absence of active autoimmune disease, inhaled or topical corticosteroids and physiologic replacement doses of adrenal corticosteroids equivalent to >10 mg/day prednisone are allowed.
- Receipt of an antitumor vaccine or live vaccine within 4 weeks before the first dose of study drug.

Subjects whom the investigator considers unsuitable due to factors that may lead to early study discontinuation, such as severe comorbidities requiring concurrent treatment (including psychiatric disorders), significantly abnormal laboratory values, or family/social conditions that may affect subject safety or data collection.
