hepatocellular carcinoma, cholangiocarcinoma, etc. by histology or cytology;

carcinoma including squamous cell carcinoma), carcinoid tumor, undifferentiated
carcinoma or other gastric cancer/gastroesophageal junction adenocarcinoma that cannot
be classified;
- Subjects with gastric adenocarcinoma/gastroesophageal junction adenocarcinoma known to
be human epidermal growth factor receptor 2 (HER2)-positive (patients with unknown
HER2 status must be confirmed at the local hospital) shall be excluded, but
HER2-positive patients with disease progression after trastuzumab treatment can be
enrolled;

- Other malignant tumors within 5 years (except for cured basal cell carcinoma of the
skin, prostate carcinoma in situ and carcinoma in situ of the cervix, etc.);

chronic diarrhea and intestinal obstruction, etc.);
- Patients with moderate to severe ascites with clinical symptoms requiring repeated
drainage; Patients with uncontrolled pleural effusion and pericardial effusion;
- Patients with any bleeding or bleeding events = CTCAE grade 3 within 4 weeks before
the first dose; Patients with arteriovenous thrombotic events, such as cerebrovascular
accident (including transient ischaemic attack), deep vein thrombosis, and pulmonary
embolism, within 6 months prior to the first dose, are allowed to be treated with low
molecular weight heparin, and antiplatelet agents are contraindicated throughout the
study period;

that may cause gastrointestinal bleeding and perforation as determined by the
investigators;

before the first dose; Patients with portal hypertension have a high risk of bleeding
considered by the investigators, or have a red sign confirmed by gastroscopy or
gastroscopy.
- Other factors that the investigator determines that the subjects are not suitable to
participate in this study;
- Subjects with Epidermal Growth Factor Receptor (EGFR) mutation and known anaplastic
