Brief summary

Relative change in 24-hour urinary protein-to-creatinine ratio (UPCR, measured in mg/g) from baseline to Week 104

Detailed description

Key secondary endpoint: Absolute change in eGFRcys in mL/min/1.73m2 from baseline to Week 104, Key secondary endpoint: Treatment response, defined as 24-hr UPCR <1000 mg/g at Week 104, Treatment response, defined as 24-hr UPCR <1000 mg/g and eGFRcys ≥85% vs. baseline at Week 104 and no treatment failure between randomisation and Week 104 (combined or multi-component endpoint), Complete remission, defined as 24-hr UPCR <300 mg/g at Week 104, Change from baseline across disease-specific COA NS-SIM-PRO at Week 104, Change from baseline across Clinical Outcome Assessment (COA) KDQOL-36 at Week 104
