Sintilimab or Placebo With Chemotherapy in Esophageal Squamous Cell Carcinoma ( ORIENT-15 )

Phase 3
Completed
Conditions
Esophageal Squamous Cell Carcinoma
Interventions
Biological: Sintilimab
Drug: Placebo
Registration Number
NCT03748134
Lead Sponsor
Innovent Biologics (Suzhou) Co. Ltd.
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

Inclusion Criteria
  • Histopathologically confirmed unresectable, locally advanced, recurrent or metastatic ESCC (excluding mixed adenosquamous carcinoma and other histological subtypes)
  • ECOG PS of 0 or 1
  • Subject must be unsuitable for definitive treatment, such as definitive chemoradiotherapy and/or surgery. For subjects who have received (neo)adjuvant or definitive chemotherapy/radiochemotherapy, time from the completion of last treatment to disease recurrence must be > 6 months Could provide archival or fresh tissues for PD-L1 expression analysis with obtainable results
  • Have at least one measurable lesion as per RECIST v1.1

Key exclusion Criteria:

  • ESCC with endoscopy-confirmed near-complete obstruction requiring interventional therapy
  • Post stent implantation in the esophagus or trachea with risk of perforation
  • Received systemic treatment for advanced or metastatic ESCC.
  • Received a cumulative dose of cisplatin ≥ 300 mg/m2 and the last cisplatin dose was within 12 months of randomization or the first dose of study treatment in the open-label phase.
  • High risk of hemorrhage or perforations due to tumor invasion in adjacent organs (aorta or trachea), or have fistula formation.
  • Hepatic metastasis > 50% of the total liver volume.
  • Received palliative therapy for a local lesion within 2 weeks prior to the first dose.
  • Received systemic treatment with Chinese traditional medicines with anti-cancer indications or immunomodulators (including thymosins, interferons, and interleukins) within 2 weeks prior to the first dose of study treatment.
  • Received systemic immunosuppressants within 2 weeks prior to randomization, excluding local use of glucocorticoids administered by nasal, inhaled, or other routes, and systemic glucocorticoids at physiological doses (no more than 10 mg/day of prednisone or equivalents), or glucocorticoids to prevent allergies to contrast media.
