Efficacy endpoints

Primary efficacy endpoint The slope of eGFR, assessed from week 6 to week 108 at the final analysis
Surrogate efficacy endpoint The proportion of patients achieving a UP/C ≤1.5 g/g and a >40% reduction from baseline in UP/C (i.e., FPRE) at week 36 (interim analysis)
Secondary efficacy endpoints The percent change in eGFR from week 6 to week 108
The percent change in eGFR from baseline to 4 wk postcessation of randomized treatment at week 112
Exploratory endpoints Slope of eGFR assessed from week 6 to week 60
Absolute and percent change in eGFR from baseline at each visit
Percent change in eGFR from week 6 at each visit
Proportion of patients achieving FPRE at each visit
Percent change in UP/C from baseline at each visit
Time to achieve FPRE
Proportion of patients reaching a confirmed 40% reduction in eGFR, ESKD (defined as initiation of renal replacement therapy, kidney transplantation, or sustained eGFR <15 ml/min per 1.73 m2), or death
Change from baseline in blood pressure at each visit
Proportion of patients requiring initiation of or intensification in immunosuppressive medication
Proportion of patients undergoing reduction in immunosuppressive medication
Change from baseline in quality of life, assessed using patient-reported outcome measures at each visit beginning at week 12
Frequency and duration of hospitalizations (for any reason and for reasons related to the kidney)
Trough plasma pharacokinetic concentrations

eGFR, estimated glomerular filtration rate; ESKD, end-stage kidney disease; FPRE, FSGS partial remission endpoint; UP/C, urinary protein-to-creatinine ratio.
