入选标准

- •Willingness to participate in the study and ability to sign an informed consent form.
- •Willingness and ability to complete all research-related procedures and site visits.
- •Characteristics of participants in the Systemic Lupus Erythematosus (SLE) trial:
- •Screen for patients with a confirmed diagnosis of SLE dating back to at least 24 weeks prior to the visit.
- •Diagnosed with systemic lupus erythematosus according to the 2019 classification criteria of the European League Against Rheumatism (EULAR) and the American College of Rheumatology (ACR).
- •Meet one of the following criteria: elevated levels of antinuclear antibodies (ANA) ≥ 1:80, positive results for anti-double-stranded DNA (anti-dsDNA) (positive results include indeterminate results), or positive results for anti-Smith (anti-Sm) antibodies.
- •Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2k) score ≥ 8 and clinical SLEDAI-2K score ≥ 4, with involvement of joints and/or skin vasculitis and/or rash manifestations (Note: Clinical SLEDAI-2K manifestations do not include complement deficiency and positivity for anti-ds-DNA antibodies).
- •Age between 18 and 75 years old (based on the date of signing the informed consent form).
- •Medications for SLE treatment:
- •Prior to the screening visit, there must be a period of background therapy of at least 12 weeks. The therapy must have been administered at a stable dose for at least 4 weeks prior to the screening visit and remain stable until randomization and throughout the duration of the study participation. If antimalarial or immunosuppressive therapy is discontinued prior to the screening visit, the last dose must have been administered at least 4 weeks prior. Detailed information on specific medications is as follows:
- •Immunosuppressants (can be used only one type; combination use is not permitted): Antimalarial drugs: Hydroxychloroquine (allowed for monotherapy; allowed in combination with one type of immunosuppressant) (maximum 400 mg/day).
- •Duration of clearance when using other immunomodulatory drugs or biologics.
- •Corticosteroids (CS) (prednisone or equivalent medication) is permitted but not required as background therapy. For trial participants using CS, the dose must be stable for at least 2 weeks prior to the screening visit, not exceed 40 mg/day during screening, and remain stable prior to randomization. Monotherapy with CS is not permitted.
- •The requirements for trial participants currently receiving long-term treatment with nonsteroidal anti-inflammatory drugs (NSAIDs) are as follows:
- •The dosage must remain stable for a period of 14 days prior to the screening visit and must remain stable until randomization and throughout the study period. The use of NSAIDs alone is not permitted.
- •A maximum of one oral NSAID (at a stable dosage) may be used during the study period.
- •The concurrent use of aspirin as a cardiovascular protective agent/to prevent thrombosis (in addition to other NSAIDs) is permitted throughout the study period, provided that the dosage remains stable.
- •Women of childbearing age must agree to use effective contraceptive measures during the study period and for 6 months thereafter, and undergo a blood pregnancy test that is negative within 7 days prior to enrollment in the study. Men must agree to use effective contraceptives during the study period and for the subsequent 6 months.
排除标准
- •Conditions other than SLE:
- •drug-induced SLE;

- •Excluded trial participants with overlapping syndromes of SLE, such as systemic sclerosis and mixed associative weaving disease;
- •In the case of a combination of antiphospholipid syndrome secondary to systemic lupus erythematosus, prior severe blood clots / obstetric complications need to be ruled out; Prophylaxis with low-dose aspirin (50-100 mg / d) in the absence of thrombotic events or obstetric comorbidities and with high-risk antiphospholipid antibody (aPL) characteristics may be included;
- •Trial participants who had had lupus encephalopathy before screening were excluded;

- •Other medical conditions and medical history;
- •Study participants who are pregnant or breastfeeding;
- •Evidence of a significant disease / condition or unstable clinical condition (e.g. kidney, Liver, blood, gastrointestinal, endocrine, lung, immune, psychiatric) or locally active infection / infectious disease which, according to medical judgement, will significantly increase the risk of the trial participants if they participate in the study;
- •Have had any major surgery within 30 days prior to the first dose of the study treatment, or planned to have any surgery during the course of the study;
- •Cancer or a history of cancer or lymphotrophic disease within the past 5 years (except adequately treated basal cell carcinoma or squamous cell carcinoma with no evidence of recurrence);

- •Currently or recently (within 3 months prior to randomization) had a gastrointestinal disease, including gastrointestinal surgery, that was likely to affect treatment absorption in the study;
- •In medical judgment, the trial participants had non-SLE concomitant conditions that may require additional systemic corticosteroid therapy during the study (e.g., asthma);
- •Severe blood loss (> 500 mL) or transfusion within 4 weeks prior to randomization;
- •It is not possible to take the drugs orally;
- •Unable to receive venous punctures and / or tolerate venous pathways;
