Exclusion Criteria:
1. History of malignancies other than gastric cancer, with the following exceptions:
1. Malignancies treated with curative intent and with no evidence of disease for 5 years;
2. Adequately treated basal cell carcinoma, squamous cell carcinoma of the skin, superficial bladder cancer, cervical carcinoma in situ, or other in situ carcinomas.
2. Conditions affecting the absorption, distribution, metabolism, or excretion of the investigational drug(s) (e.g., severe vomiting, chronic diarrhea, intestinal obstruction, malabsorption, etc.).
3. Previous allogeneic stem cell or solid organ transplantation.
4. Prior systemic antitumor therapy (including Chinese herbal medicine with antitumor indications) completed less than 4 weeks before the first dose of study treatment, or with prior treatment-related adverse events not recovered to ≤ CTCAE grade 1 (except for alopecia or pigmentation).
5. History or presence of congenital or acquired immunodeficiency disorders.
6. Active or previously documented autoimmune or inflammatory disorders (including but not limited to autoimmune hepatitis, interstitial pneumonia, inflammatory bowel disease, systemic lupus erythematosus, vasculitis, uveitis, hypophysitis, hyperthyroidism, hypothyroidism, asthma requiring bronchodilators, etc.). Patients with vitiligo, childhood asthma that has fully resolved without intervention in adulthood, or other conditions deemed eligible by the investigator may be included.
7. Use of systemic immunosuppressive therapy within 2 weeks prior to enrollment, or anticipated need for such therapy during the study, with the following exceptions:
1. Intranasal, inhaled, topical, or local corticosteroid injections (e.g., intra-articular);
2. Systemic corticosteroids at a dose ≤ 10 mg/day prednisone or equivalent;
3. Prophylactic corticosteroids for hypersensitivity reactions.
8. Known or suspected history of hypersensitivity to disitamab vedotin, anti-PD-1 agents, chimeric or humanized antibodies or fusion proteins, or any excipient of the investigational drug(s).
9. History of thrombotic or thromboembolic events within the past 6 months, such as stroke and/or transient ischemic attack, deep vein thrombosis, pulmonary embolism, etc.
10. Patients assessed by the physician to be at significant risk of bleeding, including but not limited to:
* Major bleeding (\>30 mL within 3 months) or hemoptysis (\>5 mL within 4 weeks); endoscopic evaluation may be performed to confirm eligibility;
* Active bleeding or coagulation disorders;
* Bleeding tendency or current use of thrombolytic, anticoagulant, or antiplatelet therapy.
