Brief Summary:

This is a randomized, double-blind multi-center, phase III study comparing the efficacy and safety of sintilimab or placebo in combination with chemotherapy as first-line treatment in subjects with unresectable, locally advanced recurrent or metastatic esophageal squamous cell carcinoma.

After the interim analysis conducted by the iDMC, an open-label assignment of experimental arm therapy will continue in regions outside of China, in order to further evaluate the efficacy and safety of sintilimab in combination with chemotherapy in subjects representing the western population with advanced esophageal squamous cell carcinoma

Primary Outcome Measures :
  1. OS in overall population [ Time Frame: From date of randomization until the date of death from any cause, assessed up to 40 months. ]
    To compare the overall survival of sintilimab vs. placebo, in combination with chemotherapy, for first-line treatment in subjects with unresectable, locally advanced, recurrent or metastatic esophageal squamous cell carcinoma (ESCC)

  2. OS in PD-L1 positive population [ Time Frame: From date of randomization until the date of death from any cause, assessed up to 40 months. ]
    To compare the OS of sintilimab vs. placebo, in combination with chemotherapy, for first-line treatment in subjects with PD-L1 positive, unresectable, locally advanced, recurrent or metastatic ESCC


Secondary Outcome Measures :
  1. ORR in overall population [ Time Frame: From date of randomization up to 28 months. ]
    To compare the objective response rate between the two treatment arms in ITT population

  2. PFS in overall populationsubjects in ITT population [ Time Frame: From date of randomization up to 28 months ]
    To compare the progression-free survival between the two treatment arms in ITT population

  3. DCR in overall population [ Time Frame: From date of randomization up to 28 months ]
    To compare the disease control rate between the two treatment arms in ITT population

  4. DoR in overall population [ Time Frame: From date of randomization up to 28 months ]
    To compare the duration of response between the two treatment arms in ITT population

  5. ORR - PD-L1 positive [ Time Frame: From date of randomization up to 28 months ]
    To compare the objective response rate between the two treatment arms in PD-L1 positive subjects in ITT population

  6. DCR - PD-L1 positive [ Time Frame: From date of randomization up to 28 months ]
    To compare the disease control rate between the two treatment arms in PD-L1 positive subjects in ITT population
