Brief Summary:

Dysfunction of regulatory T (Treg) cells has been detected in diverse autoimmune diseases, which can be promoted by interleukin-2 (IL-2). In a previous small sample trail performed by the investigator's group, the investigators found that the Low-dose IL-2 was effective and well tolerated in active SLE, and the effect was associated with selective modulation of CD4+ T cell subsets.

This clinical study will confirm the efficacy and safety of low dose IL-2 treatment in SLE.

The investigators perform a single-centre, double-blind pilot trial with hrIL-2 in SLE.The investigators evaluate the effectiveness and safeness of low-dose hrIL-2 for Systemic lupus erythematosus by randomized controlled study (hrIL-2 (N = 30) versus placebo group (N = 30)).

Condition or disease Intervention/treatment Phase
Systemic Lupus Erythematosus Drug: hrIL-2 active Drug: hrIL-2 placebo Phase 2

Detailed Description:
Each SLE patients (n=60) with Scores>=8 on SLEDAI received low-dose IL-2 or placebo (active group: placebo group =1:1, 1 million units every other day subcutaneously (HrIL-2 1X 106, ip, Qod) for a period of 14 days. After a 14-day rest, another cycle started) for 3 cycles. The end points were safety and clinical and immunologic response.

Arm Intervention/treatment
Active Comparator: hrIL-2 active
Intervention:Add hrIL-2 according to the protocol to original treatment. HrIL-2 active: 1 million U doses of human recombinant interleukin-2 s.c. injection
Drug: hrIL-2 active
active group: placebo group =1:1
Other Name: Human recombinant IL-2

Placebo Comparator: hrIL-2 placebo
1 million U doses of placebo s.c. injection
Drug: hrIL-2 placebo
active group: placebo group =1:1

Primary Outcome Measures :
  1. Number of Participants Who Were SLE Responders (SRI) [ Time Frame: week 24 ]
    SRI response was defined as (1) a ≥ 4-point reduction in SELENA-SLEDAI score, (2) no new BILAG A score or ≤ 1 new BILAG B score, and (3) no deterioration from baseline in the physician's global assessment by ≥ 0.3 points.

  2. Evaluation of the safety (type and number of adverse events and serious adverse events) of low-doseIL-2 in patients with SLE [ Time Frame: 24 weeks ]
    Adverse events includes injection site reactions, influenza-like symptoms, infection, fever, tumor, cardiovascular event,drug-induced liver and kidney damage.
