Safety and Efficacy Study of LymphoStat-B (Belimumab) in Subjects With Systemic Lupus Erythematosus (SLE)

Phase 2
Completed
Conditions
Lupus Erythematosus, Systemic
Interventions
Registration Number
NCT00071487
Lead Sponsor
Human Genome Sciences Inc.
Brief Summary

The purpose of this study is to evaluate the safety and efficacy of 3 different doses of belimumab, administered in addition to standard therapy, in patients with active SLE disease.

Detailed Description

The purpose of this study is to evaluate the safety and efficacy of three different doses of belimumab (1 mg/kg, 4 mg/kg, and 10 mg/kg), administered in addition to standard therapy, compared to placebo plus standard therapy in patients with active SLE disease. Patients were randomly assigned, following stratification by the screening SELENA SLEDAI score (4 to 7 versus ≥ 8), to 1 of the 4 study arms (3 active arms and 1 placebo arm plus standard therapy for SLE). All patients were to be dosed on Days 0, 14, and 28, then every 28 days for the remainder of 52 weeks. Patients completing the 52-week period could enter a 24-week open-label extension; belimumab patients received the same dose or were switched to 10 mg/kg at the investigator's discretion and former placebo patients received belimumab 10 mg/kg.

Primary Outcome Measures
NameTimeMethod
Percentage Change From Baseline in Safety of Estrogens in Lupus Erythematosus National Assessment SLE Disease Activity Index (SELENA SLEDAI) Score at Week 24.Baseline, 24 weeks

SELENA SLEDAI is calculated from 24 individual descriptors; 0 indicates inactive disease and the maximum theoretical score is 105; scores \> 20 are rare.

Time to First Mild/Moderate or Severe SLE Flare (SLE Flare Index)0 to 52 weeks

The SLE Flare Index categorized SLE flare as "mild or moderate" or "severe" based on 5 variables: 1) change in SELENA SLEDAI score from the most recent assessment to current, 2) change in signs or symptoms of disease activity, 3) change in prednisone dosage, 4) use of new medications for disease activity or hospitalization, and 5) change in Physician's Global Assessment score, a visual analog scale scored from 0 to 3 (1=mild, 2=moderate, 3=severe).

Secondary Outcome Measures
NameTimeMethod
Percentage Change From Baseline in SELENA SLEDAI Score at Week 52Baseline, 52 weeks

SELENA SLEDAI is calculated from 24 individual descriptors; 0 indicates inactive disease and the maximum theoretical score is 105; scores \> 20 are rare

Area Under the Curve (AUC) of SELENA SLEDAI Score at Week 52Baseline and every 4 to 8 weeks through Week 52

SELENA SLEDAI is calculated from 24 individual descriptors; 0 indicates inactive disease and the maximum theoretical score is 105; scores \> 20 are rare. The normalized AUC was created as the ratio of the area under the SELENA SLEDAI score curve divided by baseline score.

Percentage Change From Baseline in British Isles Lupus Activity Group (BILAG) Score at Week 52Baseline, 52 weeks

The BILAG index is a clinical measure of lupus disease activity. BILAG uses a single score for each of the 8 organ domains; range is from severe to no disease (A to E). The global BILAG score is the sum of the numerical scores in the 8 domains assigning A=9, B=3, C=1, D=0, E=0.

Area Under the Curve (AUC) of BILAG Score at Week 52Baseline and every 4 to 8 weeks through Week 52

The BILAG index is a clinical measure of lupus disease activity. BILAG uses a single score for each of the 8 organ domains; range is from severe to no disease (A to E). The global BILAG score is the sum of the numerical scores in the 8 domains assigning A=9, B=3, C=1, D=0, E=0.The normalized AUC was created as the ratio of the area under the global BILAG score curve divided by baseline score.

Time to First Type A/B SLE Flare (as Defined Using BILAG) Over 52 Weeks0 to 52 weeks

SLE flare indicates an increase in SLE disease activity. An SLE flare was a type A or B SLE flare (as defined using BILAG) compared with the previous visit.

Percentage of Patients With a Reduction in Prednisone DoseBaseline, weeks 40 to 52

Percentage of patients whose average prednisone dose has been reduced by ≥ 50% and/or has been reduced to ≤ 7.5 mg/day during Weeks 40 through 52 in patients receiving greater than 7.5 mg/day at baseline.
