NYHA for details).

• •5. Asthma and specific dermatitis, etc. requiring glucocorticoid-dependent therapy (except topical glucocorticoids).
• •6. Infections, requiring treatment for acute or chronic infections, as follows:
• •* Treatment with any inhibitory therapy currently for chronic infections (e.g., tuberculosis, pneumocystis, cytomegalovirus, herpes simplex virus, zoster virus and atypical mycobacteriosis);
• •* Hospitalization for an infection within 60 days prior to dosing;
• •* Treatment with anti-infective drugs (antibacterials, antivirals, antifungals, or antiparasites) by parenteral administration (IV or IM) 60 days prior to dosing.
• •* Subjects with mycobacterium tuberculosis, including those with a positive "T-cell spot test for tuberculosis infection (T-SPOT)" (latent tuberculosis infection: except those who have completed tuberculosis prophylaxis for 4 weeks before their first dose), or those with a positive imaging result.
• •7. Subjects with positive results from any of the following tests: hepatitis B surface antigen (HBs Ag), hepatitis B core antibody (HBc Ab), hepatitis C virus antibody (HCV Ab), human immunodeficiency virus antibody (HIV Ab), or treponema pallidum antibody (TPPA). Patients who tested positive for hepatitis B core antibody (HBc Ab) but negative for HBV-DNA should be excluded.
• •8. Hematological system diseases or hematology abnormalities: subjects with previous or current hematological system diseases (including but not limited to: myelofibrosis, anemia aplastic aregenerative, leukemia, lymphoma, etc.), hematology with hemoglobin \< 100 g/L, white blood cells \< 3.0 × 109/L, granulocytes \< 2.5 × 109/L, lymphocytes \< 0.8 × 109/L, or platelets \< 100 × 109/L.
• •9. Abnormal liver function: aspartate aminotransferase (AST) or alanine aminotransferase (ALT) or glutamyl transpeptidase (GGT) values \> 2 times ULN; or total bilirubin or alkaline phosphatase (ALP) values \> 1.5 times ULN.
• •10. Abnormal renal function: creatinine (Cr) or urea nitrogen (BUN) values \> 1.5 times the upper limit of normal (ULN); pre-screening estimated glomerular filtration rate (eGFR) ≤ 60 mL/min. Calculate eGFR values using the MDRD formula: eGFR (mL/min × 1.73 m2) = 175 × blood creatinine (\[Scr (mg/dL)\])-1.154 × age-0.203 × sex (M = 1, F = 0.742).
• •11. Cancer: history of malignancy within the last 5 years.
• •12. Transplant: history of major organ transplant (e.g., heart, lung, kidney, liver) or hematopoietic stem cell or bone marrow transplant.
• •13. Female subjects with a positive serum pregnancy test or currently lactating.
• •14. History of major surgery (craniotomy, thoracotomy, or laparotomy) or presence of unhealed wounds, ulcers, or fractures within 4 weeks prior to the first dose of study treatment.
• •15. Targeted drug therapy: rituximab within 180 days before the first dose; any drug therapy targeting T-lymphocytes, B-lymphocytes, cytokines or receptors \[e.g., belimumab, telitacicept, abatacept, etc.\] within 90 days before the first dose; JAK inhibitors within 30 days before the first dose; other investigational drugs for less than 5 half-lives.
• •16. Subjects who have participated in any other clinical trials (including receiving investigational vaccines) or received treatment with invasive and investigational medical devices within 3 months before inclusion, or are being enrolled into an interventional and investigational study.
• •17. Stable doses of anticoagulant or antiplatelet drugs used before randomization that exceeded regular doses or was increased within 7 days before dosing.
• •18. Immunosuppressants:
• •* Have received any of the following treatments within 90 days prior to screening: Intravenous immunoglobulin (IVIG);Use of high-dose glucocorticoids such as prednisone ≥ 100 mg/day;Plasma exchange, leukopheresis;Cyclophosphamide.
• •* Use of immunomodulatory agents such as thymosin within 30 days prior to screening.
• •19. Vaccination within 30 days prior to the first dose of study treatment.
• •20. Use of traditional Chinese medicinal products or herbal preparations such as total glucosides of white paeony capsules, zhengqinfengtongning and colquhounia root tablets within 30 days prior to the first dose of study treatment.
• •21. Drug abusers determined by medication history inquiries, including morphine, ketamine, tetrahydrocannabinolate, methamphetamine, dimethyldioxymethamphetamine and cocaine.
• •22. Subjects who have consumed more than 14 units of alcohol/week (1 unit of alcohol = 360 mL of beer, 150 mL of wine, or 45 mL of liquor) within 3 months prior to screening, or who cannot abstain from alcohol during the trial, as determined by history inquiries.
• •23. Other conditions: including laboratory abnormalities, history of any other disease (e.g., recent history of septicemia), clinically significant unstable or uncontrolled acute or chronic conditions unrelated to SLE (e.g., acute pneumonia, pulmonary arterial hypertension, diabetic ketoacidosis, acute pancreatitis, etc.). In the opinion of the investigator, the above conditions may confound the study results or place the subject at an inappropriate risk. Thus, the subjects who experience the conditions above are not suitable for participation in this study.
• •24. Subjects who are unsuitable for participation in this clinical study for any other reasons as determined by the investigator.
