Neoadjuvant Therapy of Targeted Immunotherapy Combined With Chemotherapy for Locally Advanced HNSCC

ClinConnect Summary

This clinical trial is investigating a new treatment approach for patients with locally advanced head and neck squamous cell carcinoma (HNSCC), a type of cancer that affects the mouth and throat. The study will explore the safety and effectiveness of combining a targeted immunotherapy drug called benmelstobart with another drug, anlotinib, and chemotherapy before surgery. This type of treatment is known as neoadjuvant therapy, which means it is given before the main treatment (surgery) to help shrink the tumor.

To participate in the trial, individuals must be between 18 and 75 years old and have a confirmed diagnosis of untreated stage III or IVa HNSCC, which includes cancers of the hypopharynx, larynx, or oral cavity. Participants should be in good general health and willing to follow the study guidelines. They will need to provide informed consent, meaning they fully understand and agree to participate in the trial. The study is not yet recruiting participants, but when it is, individuals can expect close monitoring by medical professionals throughout the treatment process. It’s also important for potential participants to know that there are several criteria that could exclude them from the trial, such as previous treatment with certain cancer therapies or having specific health conditions.

• • Pathologically confirmed, untreated patients with head and neck squamous cell carcinoma, classified as stage III, IVa according to AJCC (8th edition), including hypopharyngeal cancer, laryngeal cancer, and oral cancer;
• • Women of childbearing age must have taken reliable contraceptive measures or undergone a pregnancy test (serum or urine) within 7 days before enrollment, with a negative result, and are willing to use appropriate contraceptive methods during the trial and for 8 weeks after the last administration of the trial drug, or have undergone sterilization. For male participants, they must agree to use appropriate contraceptive methods during the trial and for 8 weeks after the last administration of the trial drug, or have undergone surgical sterilization;

• • Patients with imaging showing tumor invasion of vital perivascular tissue or whose tumor is likely to invade vital blood vessels during subsequent study and cause fatal bleeding as judged by the investigator;
• • Patients with any signs or history of bleeding diathesis, regardless of severity;
• • patients with any bleeding or hemorrhage event ≥ CTCAE Grade 2 within 4 weeks before enrollment, presence of unhealed wounds, ulcers, or fractures;
• Abnormalities in major organ functions:
• * Abnormal blood routine examination (received blood transfusion or blood products, or used G-CSF and other hematopoietic growth factors for correction within 14 days):
• • 1. Hemoglobin (HB) \< 90g/L;
• • 2. Absolute neutrophil count (ANC) \< 1.5 × 109/L;
• • 3. Platelets (PLT) \< 100 × 109/L;

• • 3. Serum creatinine (Cr) \> 1.5 × ULN or creatinine clearance rate (CCr) \< 60ml/min; ③ Abnormal Doppler ultrasound assessment: Left ventricular ejection fraction (LVEF) \< normal lower limit (60%);
• • Abnormal thyroid function: TSH \> upper limit of normal (ULN) with abnormal T3 and T4 levels;
• • Renal insufficiency: Urine routine test indicating urine protein ≥ ++, or confirmed 24-hour urine protein ≥ 1.0g;
• • Grade I or higher myocardial ischemia or myocardial infarction, arrhythmia (including QTc ≥ 480ms), and ≥ Grade 2 congestive heart failure (New York Heart Association (NYHA) classification) within 6 months before enrollment;
• • Diagnosed with other malignancies within 3 years before enrollment;
• * Patients with any severe and/or uncontrolled diseases, including:
• • <!-- -->
• • 1. Patients with uncontrolled blood pressure (systolic blood pressure ≥ 150 mmHg or diastolic blood pressure ≥ 100 mmHg); Grade I or higher myocardial ischemia or myocardial infarction, arrhythmia (including QT interval ≥ 430ms), and Grade I cardiac insufficiency (NYHA classification);
• • 2. Active or uncontrolled severe infections;
• • 3. Diseases such as cirrhosis, decompensated liver disease, active hepatitis HBV or HCV;
• • 4. Poorly controlled diabetes (fasting blood glucose (FBG) \> 10mmol/L);

• • - Presence of long-term unhealed wounds or fractures;
• • - Pulmonary hemorrhage graded \> 1 by NCI CTC AE V4.0 within 4 weeks before enrollment; hemorrhage in other locations graded \> 2 by NCI CTC AE V4.0 within 4 weeks before enrollment; patients with a tendency to bleed (such as active peptic ulcer) or receiving thrombolytic or anticoagulant therapy such as warfarin, heparin, or similar drugs;
• • - History of gastrointestinal perforation and/or fistula within 6 months before selected treatment; or history of arterial/venous thrombotic events such as cerebrovascular accidents (including transient ischemic attacks), deep venous thrombosis, and pulmonary embolism;
