Brief Summary

This study is a randomized, double-blind, multi-center, phase III clinical study comparing the clinical efficacy and safety of HLX10 or placebo combined with chemotherapy in first-line treatment of locally advanced/metastatic esophageal squamous cell carcinoma (ESCC) patients.This study consists of three periods, screening period (28 days), treatment period and follow-up period (including safety follow-up, survival follow-up).Subjects can be enrolled into this study only if they meet inclusion criteria and do not meet exclusion criteria.

Serum creatinine ≤1.5 ULN or creatinine clearance \> 60 mL/min (Cockcroft-Gault formula); N. APTT, INR and PT ≤1.5 ULN;
• For fertile female subjects, the serum pregnancy test must be negative within 7 days before the first dose.With fertile women subjects, and the partner for childbearing age women of male subjects, needs during the therapy, and after the last use HLX10 / placebo at least 3 months and the last time to use at least 6 months after chemotherapy using an approved by the medical contraception (such as intrauterine device, the pill or condoms);
• Subjects voluntarily participated in this study and signed the informed consent, with good compliance and follow-up.

You may not qualify if:

• \. BMI \< 17.5kg /m2;
• \. A history of gastrointestinal perforation and/or fistula within 6 months prior to the first administration;
• \. Obvious invasion of tumor into adjacent organs (aorta or trachea) of esophageal lesions leads to high risk of bleeding or fistula;3. Subjects after endotracheal stent implantation;
• \. Uncontrollable pleural effusion, pericardial effusion or ascites requiring repeated drainage;
• \. Previous allergies to monoclonal antibody, HLX10, 5-fu, cisplatin and other platinum drugs;
