A Randomized, Phase II Study of ivonescimab or cadonilimab or penpulimab in Combination With Cisplatin and Nab-paclitaxel in Patients With locally advanced head and neck squamous cell carcinoma (HNSCC) eligible for resection.

This proposed study will evaluate the efficacy and safety of preoperative administration of ivonescimab or cadonilimab or penpulimab combined with chemotherapy in HNSCC who are eligible for resection.

Study Overview

Patients with HBV infection capable of having detectable HBV DNA levels (≥10IU/mL or above the limit of quantitation) (manifested as positive for hepatitis B surface antigen (HbsAg) and/or hepatitis B core antibody (anti-HBc)) must receive antiviral therapy according to clinical practice at the site before randomization to ensure adequate viral suppression. Patients must maintain antiviral therapy during the study and for 6 months after the last dose of study treatment. Patients who are anti-HBc positive but do not have detectable HBV DNA (<10IU/mL or below the limit of quantitation) are not required to receive antiviral therapy unless their HBV DNA levels exceed 10IU/mL or the limit of quantitation during treatment.
10. Women of childbearing potential (15-49 years old) must have a negative pregnancy test within 7 days before starting treatment; patients of childbearing potential must agree to use effective contraception to ensure they do not become pregnant during the study period and for 3 months after stopping treatment.
11. Participants voluntarily join the study, sign an informed consent form, have good compliance, and cooperate with follow-up.

Exclusion Criteria:

1. Patients who have received any form of anti-tumor treatment previously.
2. Patients with allergic constitution and congenital immune deficiencies.

4. Patients with a history of severe bleeding tendencies or coagulation dysfunction; those who have had clinically significant bleeding symptoms within 1 month prior to the study treatment, including but not limited to gastrointestinal bleeding, hemoptysis; those who have received prolonged anticoagulation treatment within 10 days prior to the study treatment.
5. Patients who have experienced arteriovenous thrombotic events within 6 months before the study treatment, such as cerebrovascular accidents (including transient ischemic attacks, cerebral hemorrhage, cerebral infarction), deep vein thrombosis, and pulmonary embolism.
6. Patients with active autoimmune diseases or inflammatory diseases, or a history thereof, including inflammatory bowel disease (e.g., colitis or Crohn's disease), diverticulitis (excluding diverticulosis), systemic lupus erythematosus, sarcoidosis or Wegener's granulomatosis (e.g., granulomatosis with polyangiitis, Graves' disease, rheumatoid arthritis, hypophysitis, and uveitis). Exceptions to this criterion include patients with vitiligo or alopecia; patients with stable hypothyroidism after hormone replacement therapy (e.g., following Hashimoto's thyroiditis); patients with any chronic skin disease not requiring systemic treatment; inclusion of patients without active disease in the last 5 years is allowed only after consultation with the study physician.

8. Patients with uncontrollable complications, including but not limited to: persistent or active infections receiving study treatment (except HBV or HCV), symptomatic congestive heart failure, uncontrolled diabetes, uncontrolled hypertension, unstable angina, uncontrolled arrhythmias, active interstitial lung disease, severe chronic gastrointestinal disease with diarrhea, or any psychiatric/social situations that might limit compliance with study requirements, significantly increase the risk of adverse events (AE), or impair the ability of the patient to give written informed consent.
9. Pregnant or breastfeeding women.
10. Patients who do not agree to use effective contraception during the treatment period and for 3 months thereafter.
11. Patients participating in other clinical studies simultaneously.
