简要总结
The purpose of this study is to evaluate the efficacy, safety, and tolerability of belimumab in adult patients of black race with systemic lupus erythematosus (SLE; lupus).
详细描述
Study participants receive stable standard therapy for lupus in addition to receiving either placebo (no active medicine) or belimumab. The controlled period of the study is 52 weeks. The random assignment in this study is "2 to 1" which means that for every 3 participants, 2 will receive belimumab and 1 will receive placebo. Participants who successfully complete the 52-week study may enter into a 6-month open-label extension. All participants in the open-label extension receive belimumab plus standard therapy.

结局指标
主要结局
Number of Participants With Non-serious Adverse Events (nSAEs) and Serious Adverse Event (SAEs) [OL Phase]
时间窗: Week 52 to Week 84
An adverse event (AE) is any untoward medical occurrence in a clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. SAE is defined as any untoward medical occurrence that; results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect, other situations judged by physician, is associated with liver injury and impaired liver function. Number of participants who had common nSAEs (\>=5%) and any SAEs are presented. For Safety, participants that completed DB and OL phase, an additional 8 weeks follow-up was conducted (Week 84).
Percentage of Participants Achieving a Systemic Lupus Erythematosus Responder Index (SRI) Response Rate With the Modified Systemic Lupus Erythematosus Disease Activity Index- 2K (SLEDAI-2K) Scoring for Proteinuria at Week 52 [DB Phase]
时间窗: Week 52
SRI response is defined as \>=4 point reduction, from Baseline in safety of estrogen in Lupus National Assessment(SELENA)SLEDAI\[SS\] score (with modified SLEDAI-2K scoring for proteinuria \[PU\]), no worsening (increase of \<0.30 points from Baseline) in Physician's Global Assessment (PGA) and no new British Isles Lupus Assessment Group of SLE clinics(BILAG)A organ domain score \[ODS\] or 2 new BILAG B ODS compared with Baseline. Drop-outs and treatment failures were set to non-responders. Analysis performed using a logistic regression model for comparison between belimumab and placebo with covariates treatment group, Baseline SS score (with modified SLEDAI-2K scoring for PU) (\<=9 versus \[vs.\] \>=10), Baseline complement levels (low C3 and/or C4 vs. no low C3 or C4) and region (United States \[US\]/Canada vs. Rest of World). The Modified Intention-To-Treat (mITT) population comprised of safety population excluding participants who had any assessment at 3 sites (202196, 202513 or 107286).
Number of Participants With Severe AEs [OL Phase]
时间窗: Week 52 to Week 84
An AE is any untoward medical occurrence in a clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. Number of participants with severe AEs have been presented. For Safety, participants that completed DB and OL phase, an additional 8 weeks follow-up was conducted (Week 84).
Number of Participants With Worst Toxicity Grade 3 or 4 for Hematology Parameters [OL Phase]
时间窗: Week 52 to Week 84
Blood samples were collected for the assessment of hematology parameters. The parameters assessed were activated partial thromboplastin time (APTT), hemoglobin, leukocytes, neutrophils, platelets and prothrombin time. Grading was assigned as mild (Grade 1), moderate (grade 2), severe (Grade 3) and potentially life-threatening (Grade 4) according to Division of Microbiology and Infectious Diseases (DMID \[Modified from DMID Adult Toxicity Tables, 2001\]) AE Severity Grading. Number of participants with worst toxicity Grade 3 or 4 for hematology parameters have been presented.
