研究概览
简要总结
This study is to evaluate the efficacy and safety of atacicept compared to placebo in preventing new flares in subjects with systemic lupus erythematosus (SLE) and to confirm the optimal dose of atacicept for treatment of subjects with SLE and gain information on the effect of atacicept on markers specific to its mechanism of action (MoA) and their correlation to disease activity/progression. Study medication will be administered through subcutaneous (under the skin) injections, beginning with twice weekly injections for the first 4 weeks, followed by once weekly doses for 48 weeks. Following the last treatment, a safety follow-up period of 24 weeks will be conducted.

结局指标
主要结局
Percentage of Participants Experiencing a New Flare as Defined by British Isles Lupus Assessment Group (BILAG) Score A or B
时间窗: From screening up to Week 52
A flare was defined as having an adjudicated BILAG A or B score in any of the 8 organ systems during treatment, or imputed for participants who had premature treatment discontinuation. Discontinuations due to sponsor termination of the atacicept 150 mg group were not imputed as flares in this analysis. The BILAG disease activity index evaluates systemic lupus erythematosus (SLE) activity in 8 organ systems, using a separate alphabetic score (A to E) assigned to each organ system defined as follows. BILAG A: Disease sufficiently active requiring disease-modifying treatment (prednisone greater than 20 mg daily or immunosuppressants); BILAG B: Disease less active than in "A", mild reversible problems requiring only symptomatic therapy such as antimalarials, non-steroidal anti-inflammatory drugs (NSAIDs), or prednisone less than 20 mg day; BILAG C: Stable mild disease; BILAG D: System previously affected but now inactive; BILAG E: System never involved.
次要结局
- Mean Cumulative Corticosteroid Dose(Randomization up to Week 52)
- Time to First New Flare as Defined by BILAG Score A or B(From screening up to Week 52)
- Percentage of Participants Within Ordinal Response Categories for British Isles Lupus Assessment Group (BILAG) Flares(Week 52)
- Percentage of Participants Experiencing a New Flare as Defined by BILAG Score A or B During Initial 24 Weeks(From screening up to Week 24)
