    Week 24

Secondary Outcomes (6)

  • Proportion of SLE Responder Index (SRI)4 response

    Week 12 and 24

  • Prednisone dose

    Week 12 and 24

  • Immunoglobulin change from baseline

    Week 12 and 24

  • Autoantibody change from baseline

    Week 12 and 24

  • Change of complement C3 and C4 Levels from baseline

    Week 12 and 24

  • +1 more secondary outcomes

Study Arms (3)

belimumab plus low dose IL-2

EXPERIMENTAL

10mg/kg belimumab was intravenously injected to patients with systemic lupus erythematosus every month for 24 weeks. Interleukine-2 was first added to the original treatment for systemic lupus erythematosus with 1 million IU qod for 12 weeks, injected subcutaneously at the outer side of upper arm, abdomen and thigh, then the same dose of IL-2 was injected once a week for 12 weeks subcutaneously.

Drug: BelimumabDrug: Interleukin-2

belimumab

ACTIVE COMPARATOR

10mg/kg belimumab was administrated to patients with systemic lupus erythematosus for at least 24 weeks, intravenously injected every month.

Drug: Belimumab

low dose IL-2

ACTIVE COMPARATOR

The first stage: interleukine-2 was added to the original treatment for systemic lupus erythematosus with 1 million IU qod for 12 weeks, injected subcutaneously at the outer side of upper arm, abdomen and thigh; The second stage: 1 million IU IL-2 was injected once a week for 12 weeks subcutaneously.

Drug: Interleukin-2

Interventions

Belimumab was intravenously administrated at a dose of 10mg/kg once a month for at least 24 weeks.

belimumabbelimumab plus low dose IL-2

Low lose interleukine-2 at a dose of 1 million IU was injected once every other day for 12 weeks, then the same dose of IL2 was injected once a week at the second stage for 12 weeks.

Eligibility Criteria

Age18 Years - 70 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • \- 1. Male or female \>18 years of age at screening visits 2. Patients meet the American-European Consensus Group 2002 classification criteria 3. The patient must be informed in writing of the consent to participate in the trial and the patient is expected to be able to comply with the requirements of the study follow-up plan and other protocols.
  • \. Dosing of antimalarials, prednisone or equivalent, cholinergic stimulants, and topical cyclosporine required to be stable for at least 4 weeks before screening and during study; maximum doses allowed:
  • Hydroxychloroquine, 400 mg/day;
  • Prednisone, 10 mg/day

You may not qualify if:

  • \. Any subject meeting any of the following criteria should be excluded: 1. Laboratory abnormality: • Hb≤9 g/dl • Neutrophil 10 mg/d) within 1 month.
  • \. Serious complications: including heart failure (≥ New York Heart Association (NYHA) class III), renal insufficiency (creatinine clearance ≤ 30 ml/min), liver dysfunction (serum Alanine transaminase (ALT) or aspartate aminotransferase (AST) greater than three times the upper limit of normal, or total bilirubin greater than Normal upper limit) 3. Known allergies, hyperreactivity or intolerance of tofacitinib or its excipients.
  • \. Have a serious infection needing hospitalization (including but not limited to hepatitis, pneumonia, bacteremia, pyelonephritis, Epstein-Barr virus (EBV), tuberculosis infection), or use intravenous antibiotics to treat infection in 2 months before the enrollment.
  • \. Infection with HIV (HIV antibody positive serology) or hepatitis C (Hep C antibody positive serology). If seropositive, it is recommended to consult a doctor who has expertise in treating HIV or hepatitis C virus infection.
  • \. Any known history of malignancy in the past 5 years (except for nonmelanoma skin cancer, non-melanoma skin cancer or cervical tumor without recurrence within 3 months after surgical cure prior to the first study preparation).
  • \. Uncontrolled mental or emotional disorders, including a history of drug and alcohol abuse over the past 3 years, may hinder the successful completion of the study.
  • \. Pregnant, lactating women (WCBP) are reluctant to use medically approved contraceptives during treatment and 12 months after treatment.
