• Previous treatment drugs have not been adequately washed out;
• A previous history of any arterial or venous thrombosis (stroke, transient ischemic attack, myocardial infarction, deep vein thrombosis or pulmonary embolism), or clinical symptoms and medical history suggesting thrombophilia; or any of the following: cardiac arrhythmias known to increase the risk of thrombotic events (e.g., atrial fibrillation), or a corrected QT interval (QTc) >450 msec in the subject; or a history of other coagulation abnormalities;
• Confirmed diagnosis of severe lupus nephritis within 8 weeks before screening (defined as urine protein >6 g/24 hours or serum creatinine >2.5 mg/dL or 221 μmol/L), or requiring treatment with study-prohibited drugs, or having active nephritis requiring prednisone ≥100 mg/day or equivalent glucocorticoid for ≥14 days; active severe or unstable neuropsychiatric SLE, including but not limited to poorly controlled seizures, psychosis or acute confusional state, cerebrovascular accident, demyelinating syndrome, cranial nerve palsy, or evidence of active central nervous system vasculitis within 12 weeks before the screening visit;
• Hepatitis B virus (HBV) infection during the Screening Phase (if HBsAg is positive, or HBsAg is negative but anti-HBc is positive, HBV-DNA testing is required, and the subject will be excluded if viral replication is indicated); positive anti-hepatitis C virus (HCV) antibody with positive peripheral blood HCV RNA; positive human immunodeficiency virus (HIV) antibody; positive specific treponema pallidum antibody with positive rapid plasma reagin test;
