Outcomes
Primary Outcomes
Percentage Change From Baseline in Urinary Protein to Creatinine Ratio (UPCR) Based on 24-hour Urine Collection at Week 13
Time Frame: Baseline, Week 13
UPCR is a ratio between two measured substances in urine: milligram of protein per millimole (mmol) of creatinine, reported in units mg/mmol. A decrease in UPCR may be associated with improved renal and cardiovascular function.
