Descrição
Inclusion Criteria
- Signed written Informed Consent Form (ICF) and ability to comply with protocol-specified visits and related procedures.
- Age ≥ 18 years.
- Eastern Cooperative Oncology Group (ECOG) performance status score of 0 or 1.
- Expected survival ≥ 6 months.
- Histologically confirmed adenocarcinoma of the stomach or gastroesophageal junction (GEJ). For GEJ cancer, only Siewert type III and Siewert type II participants not requiring combined thoracotomy are eligible.
- Clinical stage T3-4Nany or TanyN+M0 (stage II-IVa) gastric/GEJ adenocarcinoma confirmed by endoscopic ultrasound or contrast-enhanced CT/MRI within 4 weeks before the first dose, per the American Joint Committee on Cancer (AJCC) 8th edition gastric cancer TNM staging system.
- Within 4 weeks before the first dose, evaluated by a responsible surgeon based on medical history and confirmed to meet study requirements for radical R0 resection.
Exclusion Criteria
- Histologically or cytologically confirmed other pathologic types (e.g., squamous cell carcinoma, sarcoma, undifferentiated carcinoma) or combined gastrointestinal stromal tumor (GIST) before randomization.
- Suspicious metastatic lesions or locally advanced unresectable disease, regardless of stage.
- History of gastrointestinal perforation or fistula within 6 months before randomization. May be enrolled if perforation/fistula has been surgically treated (repaired/resected) and disease recovery/remission is confirmed by the investigator.
- Active diverticulitis, intra-abdominal abscess, or gastrointestinal obstruction.
- Inability to swallow, malabsorption syndrome, or uncontrolled nausea/vomiting/diarrhea, or other severe gastrointestinal diseases affecting drug intake/absorption.
- Any life-threatening bleeding event within 3 months before randomization, or grade 3/4 gastrointestinal/variceal bleeding requiring endoscopic/surgical intervention.
- Active uncontrolled bleeding or known bleeding diathesis.

Comparador Ativo: Sintilimab
Neoadjuvant Treatment period: up to 3 cycles of sintilimab plus chemotherapy in combination with Ipilimumab N01 prior to surgery. adjuvant Treatment period: Subjects will receive 5 cycles of sintilimab plus 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. |
