- Have previously received immune checkpoint inhibitors (such as anti-PD-1 antibodies, anti-PD-L1 antibodies, anti-CTLA-4 antibodies, etc.), immune checkpoint agonists (such as antibodies targeting ICOS, CD40, CD137, GITR, and Ox40 targets, etc.), immune cell therapy, etc. Any treatment targeted at the immune mechanism of tumor.
- Subjects had an active autoimmune disease that required systemic treatment within 2 years prior to the first administration, or an autoimmune disease that was determined by the investigator to be likely to recur or for which treatment was planned.
- Active or documented inflammatory bowel disease (e.g. Crohn's disease, ulcerative colitis, or chronic diarrhea).Inability to swallow, malabsorption syndrome, or uncontrollable nausea, vomiting, diarrhea or other gastrointestinal disorders that can seriously affect the administration and absorption of drug.
- Subjects requiring systemic treatment with glucocorticoids (\> 10 mg/ day equivalent dose of prednisone) or other immunosuppressive agents within 14 days prior to the first administration.
- Known history of Immunodeficiency.
- Known history of allogeneic organ transplantation or allogeneic hematopoietic stem cell transplantation.
- Underwent major surgery or severe trauma within 28 days prior to the first administration; Underwent surgery to improve or reduce the risk of tumor complications within 14 days prior to the first administration; Or have not fully recovered from previous surgery. Significant surgery is planned within 30 days after the first administration (as determined by the investigator).
- Medical history of gastrointestinal perforation, gastrointestinal fistula, and female reproductive tract fistula within 6 months prior to the first administration; If the perforation or fistula has been treated by excision or repair and the disease has been recovered or remitted as determined by the investigator, admission is allowed.

- Known history of active tuberculosis (TB).
- Serious infections within 4 weeks prior to the first administration, including but not limited to complications requiring hospitalization, sepsis or severe pneumonia.
- An active infection requiring systemic therapy.
- Subjects with untreated chronic hepatitis B or chronic hepatitis B virus (HBV) DNA exceeding 1000 IU/ mL or active hepatitis C virus (HCV) should be excluded. Subjects with non-active HBsAg carriers, treated and stable hepatitis B (HBV DNA \<1000 IU/ mL) , and cured hepatitis C can be enrolled. Subjects with positive HCV antibodies are eligible only if the HCV RNA test results are negative.
- Known history of testing positive for human immunodeficiency virus (HIV).
- Metastases of the central nervous system, metastases of pia mater, spinal cord compression, or pia mater disease confirmed by imaging or pathological examination.
- Uncontrolled pleural effusion, pericardial effusion, or ascites requiring repeated drainage.
- Clinically active hemoptysis, active diverticulitis, peritoneal abscess, or gastrointestinal obstruction.
- Unresolved toxicities from prior anticancer therapy, defined as having not resolved to NCI CTCAE v5.0 Grade 0 or 1, or to levels dictated in the inclusion/exclusion criteria.
