Official Title

A Phase 3/4, Multi-Center, Randomized, Double-Blind, Placebo-Controlled, 52-Week Study to Evaluate the Efficacy and Safety of Belimumab (HGS1006) in Adult Subjects of Black Race With Systemic Lupus Erythematosus (SLE)

Brief Overview

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).


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.
