- 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.
