Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryPercent Change in 24-hour Urinary Oxalate Excretion Corrected for Body Surface Area (BSA) From Baseline to Month 6Baseline to Month 6
Percent change in 24-hour urinary oxalate excretion corrected for BSA was estimated by an average percent change from baseline across Months 3 through 6. Only valid urine samples without any non-protocol-related issues were included in the analysis. A negative change from Baseline indicates a favorable outcome.
SecondaryAbsolute Change in 24-hour Urinary Oxalate Corrected for BSA From Baseline to Month 6Baseline to Month 6
Absolute change in 24-hour urinary oxalate excretion corrected for BSA was estimated by an average absolute change from baseline across Months 3 through 6. Only valid urine samples without any non-protocol-related issues were included in the analysis. A negative change from Baseline indicates a favorable outcome.
SecondaryPercent Change in 24-hour Urinary Oxalate:Creatinine Ratio From Baseline to Month 6Baseline to Month 6
Percent change in 24-hour urinary oxalate:creatine ratio was estimated by an average percent change from baseline across Months 3 through 6. A negative change from Baseline indicates a favorable outcome.
SecondaryPercentage of Participants With 24-hour Urinary Oxalate Level Corrected for BSA at or Below 1.5 x ULN at Month 6Month 6The upper limit of normal (ULN) = 0.514 mmol/24hr/1.73m\^2 for 24-hour urinary oxalate excretion corrected for BSA.
SecondaryPercentage of Participants With 24-hour Urinary Oxalate Level Corrected for BSA at or Below ULN at Month 6Month 6The upper limit of normal (ULN) = 0.514 mmol/24hr/1.73m\^2 for 24-hour urinary oxalate excretion corrected for BSA.
SecondaryPercentage Change in Plasma Oxalate From Baseline to Month 6Baseline to Month 6Percent change in plasma oxalate (umol/L) was estimated by an average percent change from baseline across Months 3 through 6. A negative change from Baseline indicates a favorable outcome.
SecondaryAbsolute Change in Plasma Oxalate From Baseline to Month 6Baseline to Month 6Absolute change in plasma oxalate (umol/L) was estimated by an average percent change from baseline across Months 3 through 6. A negative change from Baseline indicates a favorable outcome.
SecondaryChange in Estimated Glomerular Filtration Rate (eGFR) From Baseline to Week 2 and Months 1, 2, 3, 4, 5 and 6Baseline, Week 2, Months 1, 2, 3, 4, 5 and 6
eGFR is calculated from serum creatinine based on the Modification of Diet in Renal Disease formula for patients ≥18 years of age and the Schwartz Bedside Formula for patients \>1 year to \<18 years of age at screening. Change from baseline to Month 6 is reported.
SecondaryAbsolute Change in 24-hour Urinary Oxalate Excretion Corrected for BSA From Baseline in the Extension PeriodFrom Baseline to Month 54 and Month 60
Absolute change in 24-hour urinary oxalate excretion corrected for BSA was estimated by an average absolute change from baseline in the extension periods. Only valid urine samples without any non-protocol-related issues were included in the analysis. A negative change from Baseline indicates a favorable outcome.
SecondaryPercentage Change in 24-hour Urinary Oxalate Excretion Corrected by BSA From Baseline in the Extension PeriodFrom Baseline to Month 54 and Month 60
Percent change in 24-hour urinary oxalate excretion corrected for BSA was estimated by an average percent change from baseline in the extension periods. Only valid urine samples without any non-protocol-related issues were included in the analysis. A negative change from Baseline indicates a favorable outcome.
