Percent Change in Urine Protein From Baseline (Day 1) to Week 16 Primary · Baseline; Week 16

Urine protein was assessed by urinary protein excretion during a 24-hour urine collection.

Filgotinib 200 mg-51.2± 25.67
Change From Baseline (Day 1) in Urine Protein at Week 16 Secondary · Baseline; Week 16

Urine protein was assessed by urinary protein excretion during a 24-hour urine collection.

Percentage of Participants With Partial Remission at Week 16 Secondary · Week 16

Partial Remission was defined as urine protein excretion below \< 3 g/day and urine protein excretion decrease by ≥ 50% among participants with baseline (Day 1) nephrotic range proteinuria \[urine protein excretion ≥ 3 g/day\]; or urine protein excretion decrease by ≥ 50% among participants with subnephrotic range proteinuria \[urine protein excretion \< 3 g/day\]).

GroupValue95% CI
Lanraplenib 30 mg0
Filgotinib 200 mg50.0
Percentage of Participants With Complete Remission at Week 16 Secondary · Week 16

Complete Remission was defined as urine protein excretion below 0.5 g/day, with no hematuria.

GroupValue95% CI
