Критерии участия

Критерии включения

• The subjects voluntarily joined this study, signed the Informed Consent Form (ICF), and showed good compliance;
• On the date of signing the ICF, aged between 18 and 75 years old (inclusive);

If the lesion has undergone local treatment (radiotherapy, ablation, interventional therapy, etc.) in the past, it must be clearly proven to have progressed in accordance with RECIST v1.1 before it can be considered a measurable lesion;

7\. Eastern Cooperative Oncology Group (ECOG) score from 0 to 1; Expected survival is greater than 12 weeks; 9. The laboratory inspection meets the protocol standards; 10. Women of childbearing age should agree to use effective contraceptive measures during the study period and within 6 months after the end of the study, and have a negative serum test within 7 days before enrollment in the study; Men should agree to use effective contraceptive measures during the study period and within 6 months after the end of the study period;

Критерии исключения

• Have had or currently have other malignant tumors within the past 5 years prior to the first use of medication;
• There are various factors that affect intravenous injection, venous blood collection diseases, or oral medication (such as inability to swallow, chronic diarrhea, and intestinal obstruction);

• Those who have received major surgical treatment, significant traumatic injury, or are expected to undergo major surgery during the expected study treatment period within 4 weeks before the first medication, or have long-term untreated wounds or fractures;
• Subjects who experience any bleeding or bleeding events ≥ NCI CTCAE v5.0 grade 3 within 4 weeks prior to the first administration;
• Individuals who have experienced arterial/venous thrombotic events within 6 months prior to the first administration, such as cerebrovascular accidents (including transient ischemic attacks), deep vein thrombosis, pulmonary embolism, or any other history of severe thromboembolism (implantable venous infusion port or catheter-related thrombosis, or superficial vein thrombosis is not considered "severe" thromboembolism);
• hepatitis B virus (HBV) infected individuals cannot receive regular antiviral treatment throughout the entire process; HCV infected individuals (HCV Ab or HCV RNA positive): Researchers determine that they are in an unstable state or need to continue antiviral treatment. Regular antiviral treatment cannot be accepted during the study;
• Active syphilis infected individuals who require treatment;
• History of active pulmonary tuberculosis, idiopathic pulmonary fibrosis, organizing pneumonia, drug-induced pneumonia, radiation pneumonitis requiring treatment, or clinically symptomatic active pneumonia;

• Tumor related symptoms are difficult to control;
• Known to be allergic to the components of research drug excipients;
• Those who have participated in and used other anti-tumor clinical trial drugs within 4 weeks before the first medication;
