Критерии исключения

• Complicated diseases and medical history:

• Have had or are currently suffering from other malignant tumors within 3 years before the first medication;
• Unmitigated toxic effects higher than grade 1 of Common Terminology Criteria for Adverse Events (CTCAE) due to any previous treatment;
• Major surgical treatment, significant traumatic injury, or long-term unhealed wounds or fractures have been received within 4 weeks prior to initial medication;
• Patients with any bleeding or bleeding events ≥CTCAE grade 3 within 4 weeks before the first dose; Aortic/venous thrombosis events, such as cerebrovascular accidents (including transient ischemic attacks), deep vein thrombosis, and pulmonary embolism, occurred within 6 months prior to initial administration; Treatment with low molecular weight heparin was permitted and antiplatelet drugs were prohibited throughout the study period;
• Active viral hepatitis with poor control;
• There is a history of active tuberculosis, idiopathic pulmonary fibrosis, institutional pneumonia, drug-induced pneumonia, radiation pneumonia requiring treatment or active pneumonia with clinical symptoms;
• Have a history of psychotropic drug abuse and can not quit or have mental disorders;
• People who are ready to undergo or have previously received allogeneic bone marrow transplantation or solid organ transplantation;
• Have a history of hepatic encephalopathy;
• Currently on or recently used (within 7 days before the start of study treatment) aspirin (>325 mg/ day (maximum antiplatelet dose) or dipyridamole, ticlopidine, clopidogrel, and cilostazol;
• Subjects with any severe and/or uncontrolled disease.
• Tumor related and treatment:

• For subjects who have received chemotherapy, immunotherapy within 3 weeks before the first dose, radiation therapy or small molecule targeted drugs within 2 weeks, or who are still within the 5 half-lives of the drug (as the shortest time of occurrence), the washout period is calculated from the end time of the last treatment;
• Within 2 weeks before the first use of the drug, the treatment of Chinese patent drugs with anti-tumor indications specified in the National Medical Products Administration (NMPA) approved drug instructions;
• Imaging including computed tomography (CT) or magnetic resonance imaging (MRI) shows that the tumor has invaded important blood vessels, or the investigator determines that the tumor is highly likely to invade important blood vessels during the follow-up study period and cause fatal massive bleeding;
• Uncontrolled pleural effusion, pericardial effusion or moderate to severe ascites that still require repeated drainage;
• Obvious biliary obstruction (except for total bilirubin ≤ 2× upper limit of normal (ULN) after endoscopic stent placement and percutaneous transhepatic biliary drainage);
• Known spinal cord compression, cancerous meningitis, with symptoms of brain metastases, or symptoms controlled for less than 4 weeks.
• Research treatment related:

• Known allergy to study drug excipients;
• Have previously received anti-HER2 therapy drugs (only for the second stage, the first stage is not limited);
• Patients who require immunosuppressive, systemic, or absorbable topical hormone therapy for immunosuppressive purposes and who continue to use it for 7 days prior to initial administration (except for corticosteroids <10 mg per day of prednisone or other therapeutic hormones).
• Participants who participated in and used other anti-tumor clinical trials within 4 weeks before the first medication.
• According to the judgment of the researcher, there is a situation that seriously endangers the safety of the subjects or affects the completion of the study.
