Phase 2 Study of Belimumab Administered Subcutaneously to Subjects With Systemic Lupus Erythematosus (SLE)

Phase 2
Terminated
Conditions
Systemic Lupus Erythematosus
Interventions
Registration Number
NCT00732940
Lead Sponsor
Human Genome Sciences Inc.
Brief Summary

The purpose of this study is to test the safety and tolerability of repeated subcutaneous (SC) doses of belimumab in subjects with SLE.

Detailed Description

This clinical trial will evaluate the safety, pharmacokinetics (PK), and effect on biomarkers of repeated subcutaneous (SC) administration of belimumab in subjects with SLE. As data permit, an exploratory pharmacodynamic analysis will be performed to evaluate the correlation between belimumab serum exposure, PGA, SELENA SELDAI, and biomarker effects.

Absolute Change From Baseline in Physician's Global Assessment (PGA) Score at Week 24Baseline, 24 Weeks

PGA is a visual analog scale scored from 0 to 3. A score of 1 corresponds to mild lupus disease activity. A score of 2 correlates with moderate disease activity and a score of 3 with severe disease activity.

The PGA is a visual analog scale scored from 0 to 3. A score of 1 corresponds to mild lupus disease activity. A score of 2 correlates with moderate disease activity and a score of 3 with severe disease activity.
