Brief Summary

This study is a randomized, controlled, open-label, multicenter Phase III clinical trial, designed to evaluate the efficacy and safety of neoadjuvant toripalimab in combination with nab-paclitaxel and platinum versus neoadjuvant docetaxel in combination with cisplatin and 5-fluorouracil (DCF) in the treatment of resectable locally advanced esophageal squamous cell carcinoma

     3. Kidney: Serum creatinine ≤1.5×ULN or calculated creatinine clearance (CrCl) ≥60 mL/min (using the Cockcroft-Gault formula);
     4. Coagulation function: International normalized ratio (INR) ≤1.5, and prothrombin time (PT) or activated partial thromboplastin time (APTT) ≤1.5×ULN;

  10. Fertile males or females of childbearing potential must use effective contraception methods (such as oral contraceptives, intrauterine devices, or barrier methods combined with spermicides) during the trial and continue contraception for 6 months after the end of treatment;

  11. Good compliance and willingness to cooperate with follow-up visits.

Exclusion Criteria

• Patients who meet any of the following criteria are ineligible for this study:

  1. Previous treatment with PD-1/PD-L1 agents or drugs targeting another T-cell receptor (e.g., CTLA-4, OX-40, etc.);

  2. Presence of uncontrollable pleural effusion, pericardial effusion, or ascites requiring repeated drainage;

  3. Active autoimmune disease or suspicion of such, including but not limited to systemic lupus erythematosus, rheumatoid arthritis, inflammatory bowel disease, etc., with the exception of type 1 diabetes and hypothyroidism controlled with stable-dose replacement therapy, and skin diseases not requiring systemic treatment (e.g., psoriasis, vitiligo);

  4. History of interstitial lung disease ≥ Grade 2;

  5. Received systemic corticosteroids (prednisone >10mg/day or equivalent) or other immunosuppressive drugs within 14 days prior to the first study drug administration;

  6. History of immunodeficiency, including other acquired or congenital immunodeficiency diseases, history of organ transplantation, or having undergone allogeneic hematopoietic stem cell transplantation or solid organ transplantation;

  7. Received live vaccine within 4 weeks prior to the first study drug administration;

  8. Presence of severe cardiovascular and cerebrovascular diseases:

     1. Uncontrolled hypertension or pulmonary arterial hypertension;
     2. Unstable angina or myocardial infarction, coronary artery bypass grafting, or stent implantation within 6 months prior to study drug administration;
     3. Chronic heart failure with cardiac function ≥ Grade 2 (New York Heart Association [NYHA] classification);
     4. Left ventricular ejection fraction (LVEF) <50%;
     5. Severe arrhythmias requiring drug treatment (excluding atrial fibrillation or paroxysmal supraventricular tachycardia). For example: male QTcF >450 msec or female QTcF >470 msec, complete left bundle branch block, third-degree atrioventricular block;
     6. Cerebrovascular accident (CVA) or transient ischemic attack (TIA) within 6 months prior to study drug administration;
