About

The purpose of this study is to explore the effectiveness and safety of neoadjuvant immune combined chemotherapy or radiochemotherapy compared with traditional neoadjuvant radiochemotherapy in patients with locally advanced Esophageal Squamous Cell Carcinoma.

Full description

This study aimed to evaluate the efficacy and safety of adding immunotherapy to neoadjuvant chemotherapy (CT) or chemoradiotherapy (CRT) compared to neoadjuvant CRT alone for resectable locally advanced esophageal squamous cell carcinoma (ESCC)

Enrollment: 426 estimated patients

7. Voluntarily sign an informed consent form before treatment;
8. Plan to receive surgical treatment after neoadjuvant treatment is completed;
9. No surgical contraindications;
10. Normal function of major organs
11. Female subjects with fertility must undergo a serum pregnancy test within 72 hours before starting the study drug administration, and the result is negative, and take effective contraception during the trial and at least 3 months after the last administration Measures (such as intrauterine devices, contraceptives, or condoms); for male subjects whose partners are females of childbearing age, effective contraceptive measures should be taken during the trial and within 3 months after the last administration;
12. The subjects have good compliance and can follow up the efficacy and adverse events/reactions according to the requirements of the plan;

Immunosuppressive drugs or systemic hormone drugs are being used within 2 weeks before the first use of the study drug to achieve immunosuppressive purposes (dose>10mg/day prednisone or equivalent dose); if there is no active autoimmune disease In the case of inhalation or topical use of steroids and prednisone doses> 10 mg/day or equivalent doses of adrenal cortex hormone replacement are allowed;
   3. Received a live attenuated vaccine within 4 weeks before using the study drug for the first time;
   4. Have undergone major surgery or severe trauma within 4 weeks before using the study drug for the first time;

7. There are clinical symptoms or diseases of the heart that are not well controlled;

8. Severe infections (CTCAE v5.0> level 2) occurred within 4 weeks before the first use of the study drug, such as severe pneumonia, bacteremia, infectious comorbidities that require hospitalization, etc.; baseline chest imaging examinations suggest activity Pulmonary inflammation, symptoms and signs of infection in the 14 days before the first use of the study drug, or those who require oral or intravenous antibiotic treatment, except for the prophylactic use of antibiotics;

9. Participated in other drug clinical studies within 4 weeks before randomization;

10. People who are currently accompanied by interstitial pneumonia or interstitial lung disease, or have a history of interstitial pneumonia or interstitial lung disease that requires hormone therapy, or have other pulmonary fibrosis that may interfere with the judgment and management of immune-related lung toxicity , Organizing pneumonia (such as bronchiolitis obliterans), pneumoconiosis, drug-related pneumonia, idiopathic pneumonia, or subjects whose CT shows active pneumonia or severe lung dysfunction during the screening period; active tuberculosis;

11. Patients with any active autoimmune diseases or history of autoimmune diseases with the possibility of recurrence; patients with skin diseases that do not require systemic treatment, such as leukoplakia, psoriasis, hair loss, and insulin treatment Patients with controllable type I diabetes or a history of asthma, but who have been completely relieved during childhood without any intervention can be included in the group; patients with asthma who need bronchodilator intervention cannot be included in the group;

13. Other malignant tumors have been diagnosed within 5 years before the first use of the study drug, unless malignant tumors with low risk of metastasis or death (5-year survival rate> 90%), such as fully treated skin basal cell carcinoma or squamous cell Skin cancer or cervical carcinoma in situ, etc., may be considered for inclusion;

14. Women who are pregnant or breastfeeding;

15. According to the judgment of the investigator, there are other factors that may lead to the forced termination of the study, such as suffering from other serious diseases (including mental illness) requiring combined treatment, alcoholism, drug abuse, family or social factors, which may affect the subjects Factors of safety or compliance.
