Clinical Trial Summary

In patients with locally advanced head and neck squamous cell carcinoma undergoing standard surgical treatment after neoadjuvant immunochemotherapy, can PD-1 inhibitor therapy be used instead of adjuvant radiotherapy for both primary and lymph node pathology? To provide further evidence-based medical evidence for the late precision treatment of HNSCC patients after neoadjuvant immunochemotherapy. Avoid the side effects caused by excessive radiotherapy, especially avoid the occurrence of second primary cancer, radiation osteonecrosis and other diseases.

1. Main study endpoint:

A randomized controlled, non-inferiority, multicentre Phase III trial was conducted to investigate the difference in 5-year overall survival (OS) between experimental group (Group B) and control group (group A) in patients undergoing standard surgical treatment after neoadjuvant immunochemotherapy for locally advanced HNSCC, with both primary and lymph node pathology revealed by pCR. At the same time, adverse events and safety were evaluated according to NCI-CTCAE 5.0 criteria and RTOG later radiotherapy damage evaluation criteria.

Safety indicators focused on late radiotherapy toxicity and the incidence of grade 3 and 4 adverse reactions in NCI-CTC AE 5.0 and RTOG. The differences in the incidence of grade 3 and 4 adverse events were compared between the experimental group and the control group.

2. Secondary study endpoint:

The differences in 2-year disease-free survival (DFS), regional relapse-free survival (RRFS), distant metastasis free survival (DMFS), safety and adverse events were compared.

Safety evaluation NCI-CTC AE 5.0 standard was used to evaluate the acute safety index of radiotherapy, and RTOG late-stage damage evaluation standard was used to evaluate the late-stage safety index of radiotherapy.

4) Exploratory goals The influence of prognostic laboratory indicators, clinical risk factors were analyzed. To explore the factors that influence the efficacy of radiotherapy after pCR immunotherapy.

7. Good coagulation function, defined as International Standardized ratio (INR) or prothrombin time (PT) =1.5 times ULN;

8. Normal thyroid function, defined as thyroid stimulating hormone (TSH) within the normal range. Subjects whose baseline TSH is outside the normal range can be enrolled if total T3 (or FT3) and FT4 are within the normal range;

9. The myocardial enzyme profile was within the normal range (if the researchers comprehensively judged that the simple laboratory abnormality was not clinically significant, it was also allowed to be included);

10. For female subjects of childbearing age, a urine or serum pregnancy test should be tested negative within 3 days prior to receiving the first study drug administration (day 1 of Cycle 1). If the urine pregnancy test results cannot be confirmed negative, a blood pregnancy test is requested. Women of non-reproductive age were defined as at least one year after menopause or having undergone surgical sterilization or hysterectomy;

11. If there is a risk of conception, all subjects (male or female) shall use contraception with an annual failure rate of less than 1% for the entire duration of treatment up to 120 days after the last study drug administration (or 180 days after the last chemotherapeutic drug administration).

Exclusion Criteria:

• 1 HNSCC is not the initial diagnosis of other malignant tumors or neoadjuvant therapy.

• Prior to treatment An active autoimmune immune disease requiring systemic therapy (e.g. the use of disease-modifying drugs, glucocorticoids, or immunosuppressants) has occurred in the last 2 years.

• Untreated active hepatitis B (defined as HBsAg positive and HBV-DNA copy number detected greater than the upper limit of normal value in the laboratory of the study center);

Note: Hepatitis B subjects who meet the following criteria can also be enrolled:

1) HBV viral load < before initial administration; At 1000 copies /ml (200 IU/ml), subjects should receive anti-HBV therapy to avoid viral reactivation throughout the study treatment period 2) For subjects with anti-HBC (+), HBsAg (-), anti-HBS (-), and HBV viral load (-), prophylactic anti-HBV therapy is not required, but close monitoring of viral reactivation is required

• Active HCV infected subjects (HCV antibody positive and HCV-RNA level above the lower limit);

• Pregnant or lactating women;

• The presence of any serious or uncontrolled systemic disease, such as:

1. The resting electrocardiogram (ECG) presents significant and severely uncontrollable abnormalities in rhythm, conduction or morphology, such as complete left bundle branch block, ? degree or above heart block, ventricular arrhythmia or atrial fibrillation;

2. Unstable angina pectoris, congestive heart failure, and NYHA grade = 2 chronic heart failure;

3. Any arterial thrombosis, embolism or ischemia, such as myocardial infarction, unstable angina pectoris, cerebrovascular accident or transient ischemic attack, occurred within 6 months before treatment;
