Trial overview
Official title: The Evaluation Of Use of Belimumab in Routine Care SEttings in Lupus Nephritis (LN): the OBSErve-LN Study
Trial description: 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.

Timeframe: At Month 24
Secondary outcomes:
Number of Participants Achieving Modified Partial Renal Response (<=20% Decline in eGFR and <=0.7 Urine Protein-Creatinine Ratio [uPCR]) and Modified Complete Renal Response (<=10% Decline in eGFR and <=0.5 uPCR)
Timeframe: At Months 24 and 60
Number of Participants Maintaining Renal Function (<=30% Decline in eGFR from the Initiation of Belimumab) and Not Requiring Renal Replacement Therapy (in Those that Remain Adherent to Belimumab) at Month 24
