Single Dose:
1. Male or female, 18-65 years old (inclusive), weight of ≥ 45 kg.
2. Definite diagnosis of systemic lupus erythematosus (see Annex 3. SLE Classification Criteria by SLICC 2012 for diagnostic criteria), and an SLE disease activity index (SLEDAI) score of \< 15 (see Annex 4.

3. If a subject is receiving SLE treatment, a stable SLE regimen must be maintained up to the date of the first dose of study drug (the permitted medications and their maximum doses are as follows):
* Glucocorticoids: prednisone 10 mg/day or other glucocorticoids with an equivalent dose. It should be stable for at least 4 weeks prior to receiving the first dose of study drug.
* Other immunosuppressive drugs alone or in combination with glucocorticoids include the following: azathioprine (maximum dose of 100 mg/day), methotrexate (maximum dose of 15 mg/week), mycophenolate mofetil (maximum dose of 1500 mg/day), tripterygium wilfordii polyglycosides (maximum dose of 60 mg/day), leflunomide (maximum dose of 20 mg/day), tacrolimus (maximum dose of 4 mg/day), ciclosporin (maximum dose of 100 mg/day). The above medications should be used for at least 12 weeks and stable for at least 4 weeks prior to receiving the first dose of study drug.
* Hydroxychloroquine: The maximum allowable dose is 400 mg/day, and combination with the immunosuppressants listed above is allowed. It should be used for at least 12 weeks and the dose should be stable for at least 4 weeks prior to receiving the first dose of study drug.
4. The subject is willing to participate in the study and voluntarily sign the ICF.
5. Subjects of childbearing potential or subjects with a partner of childbearing potential must agree to use effective contraceptive measures throughout the study (except oral estrogens, estrogenic vaginal ring, etc., refer to Annex 5. Contraceptive Measures, Definitions of Women of Childbearing Potential and Contraception Requirements for optional contraceptive methods).
6. dsDNA antibody titer (ELISA) greater than or equal to 1.5 times the upper limit of normal (ULN).

3. Cardiovascular disorders: history of acute myocardial infarction, or unstable angina, severe arrhythmia (multifocal frequent ventricular premature beats, ventricular tachycardia, ventricular fibrillation), etc. over the past six months; New York Heart Association (NYHA) Class III-IV (see Annex 6. NYHA for details).
4. Subjects with a known history of moderate or severe persistent asthma (assessed by the Asthma Severity Scale of the National Heart, Lung, and Blood Institute \[NHLB\]) within the past 5 years, or who currently have uncontrolled asthma (of any grade).
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).

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.
