What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 3 trials are large pivotal studies comparing the treatment to current standard of care or placebo. Your participation directly contributes to the evidence needed for regulatory approval.

This trial targets 40 participants in total. It began in 2024-02-02 with a primary completion date of 2025-11-22.

Brief Summary

This study is a prospective, open-label, single-arm, single-center clinical study, aiming to evaluate the efficacy and safety of sintilimab combined with platinum-based chemotherapy + pegylated recombinant human granulocyte stimulating factor as neoadjuvant treatment for resectable esophageal squamous cell carcinoma patients. In the study, all patients who meet the inclusion criteria will receive sintilimab combined with platinum-based chemotherapy for 2 cycles (21 days as one cycle) as neoadjuvant treatment according to the study plan. Pegylated recombinant human granulocyte stimulating factor will be given 24 hours after the end of chemotherapy, and radical surgical treatment will be received within 3-6 weeks after the completion of the last neoadjuvant treatment. Whether the subjects need adjuvant treatment after surgery and the adjuvant treatment plan will be determined by the investigators. All subjects need to complete the follow-up plan formulated by the study after surgery.

Patients allergic to the drugs or related components involved in this study; 12. Patients currently participating in other clinical studies; 13. Patients who received anti-programmed death-1 (PD-1)/PD-1 ligand (PD-L1) monoclonal antibodies, cytotoxic T lymphocyte-associated antigen-4 (CTLA-4) antibodies or other immune or molecular targeted therapies within 4 weeks before screening; 14.
