Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is a randomized, double-blind Phase 3 study to compare the efficacy and safety of Sindilizumab combined with chemotherapy or placebo combined with chemotherapy for neoadjuvant and adjuvant therapy for Resectable Stage II to IIIB (resectable N2 only) non-small cell lung cancer (NSCLC).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Sintilimab

Neoadjuvant Treatment period: up to 3 cycles of sintilimab plus platinum-based chemotherapy prior to surgery.

adjuvant Treatment period: Subjects will receive 1 cycle of sintilimab plus platinum-based chemotherapy, and then receive sintilimab therapy after surgery until disease recurrence, unacceptable toxicity, receiving new anti-tumor therapy, withdrawal of informed consent (ICF), lost to follow-up or death, or other conditions that require treatment discontinuation (whichever occurs first). The maximum duration of postoperative treatment with either sintilimab or placebo is 13 cycles.
