Study to Assess Real-world Effectiveness of Belimumab for Treatment of Adults With LN

Summary

The purpose of the OBSErve-LN study is to assess the real-world use and effectiveness of belimumab in routine practice for the treatment of adults with active LN in multiple countries of interest. This study aims to provide the first long-term (up to 5 years) assessment of renal function preservation in belimumab treated participants.
