Coagulation function: Activated partial thromboplastin time (APPT) and International Normalized Ratio (INR)1.5 X ULN (No anticoagulants or other drugs affecting clotting function were used within 14 days prior to the first administration, except for subjects requiring long-term anticoagulant therapy)

\. Prior therapy with any other antibody or drug specifically targeting T-cell co-stimulation or checkpoint pathways including anti-PD-1, anti-PD-L1, anti CTLA-4, OX40 agonist, and anti-CD137, etc
\. Immune-related adverse events of grade 3 or higherNCI-CTCAE 5.0after immune therapy
\. Have received major surgery or radical radiotherapy within 28 days, or palliative radiotherapy within 14 days, or radiological agents (strontium, samarium, etc.) within 56 days prior to screening
\. Have received systemic anti-tumour therapy 28 days before the first dose, including but not limited to chemotherapy, immunotherapy, macromolecular targeted therapy, and biological therapy (tumour vaccine, cytokines or growth factors controlling cancer); Patients who received small-molecule targeted and oral fluorouracil therapy within 14 days before the first dose
\. Have received attenuated live vaccine within 28 days before the first dose or planned to receive during the study period
