You may not qualify if:

• Those who have previously received antibody treatment with any tumor necrosis factor receptor (TNFR) superfamily agonists, such as CD40, OX40, CD137, CD27, CD357, etc.;
• Those who have received anti-tumor therapy 4 weeks before the first administration or within 5 half-lives of the drug (whichever is shorter);
• Chronic systemic glucocorticoid therapy within 2 weeks prior to initial administration (daily dose equivalent to prednisone \> 10mg of systemic corticosteroids) or any other form of immunosuppressive therapy;
• The toxicity of previous anti-tumor therapy has not returned to CTCAE5.0 version of the definition ≤ Class 1 (except hair loss);
• A history of cancer within the past 5 years, except for locally curable cancers (radical melanoma, basal or squamous cell carcinoma, carcinoma in situ of the bladder or cervix);
• Patients with primary central nervous system (CNS) malignancies, CNS metastases after local treatment failure, and cancerous meningitis; Patients with asymptomatic brain metastases or stable neurological symptoms without steroid hormones or other BMS for ≥4 weeks could be enrolled.
• Patients with a history of organ transplantation or allogeneic bone marrow transplantation or who have received autologous stem cell transplantation within 3 months before the first administration of the drug;
• Those who have undergone major surgery or have not recovered from surgery within 4 weeks prior to the first dosing (except for diagnostic surgery);
• Physical examination or laboratory examination, any of the following conditions:
• Hepatitis B: HBsAg positive and/or HBcAb positive with HBV-DNA titers positive or higher than the upper limit of normal (excluded if only the lower limit of detection is present); Hepatitis C: HCV antibody positive and HCV-RNA positive or greater than the upper limit of normal; Human immunodeficiency virus (Anti-HIV) positive; active treponema pallidum infection;
• Uncontrolled or severe cardiovascular disease, such as New York Heart Association (NYHA) Class II or above congestive heart failure, unstable angina, myocardial infarction and other cardiovascular disease, poorly controlled arrhythmias, within 6 months before the first administration of the drug. Difficult to control hypertension (systolic blood pressure ≥160mmHg and/or diastolic blood pressure ≥100mmHg after adequate treatment);
• Patients with a history of the following, including but not limited to active autoimmune diseases, active infections (such as active tuberculosis), severe mental illness, and severe endocrine disorders;
• Patients who have been treated with any other investigational drug/device within 4 weeks prior to initial administration;
• Have a history of drug abuse or alcoholism within 6 months before the first dose;
