Rate of Renal Stone Events |
A renal stone event is defined as a patient-reported event that includes =1 of the following: visit to healthcare provider because of a renal stone; medication for renal colic; stone passage; macroscopic hematuria due to a renal stone. Lower rates indicate a favorable outcome. |

Change From Baseline in Nephrocalcinosis as Assessed by Renal Ultrasound |
Renal ultrasound data were used to grade medullary nephrocalcinosis findings (range: 0 to 3), where a higher grade indicates greater severity. Improving=if both sides improve, or one side improves and the other side has no change; No change=if both sides have no change; Worsening=if both sides worsen, or one side worsens and the other side has no change; Indeterminate=if one side improves and the other side worsens. |
Baseline, Month 6 |

Primary |
Percent Change in 24-hour Urinary Oxalate Excretion Corrected for Body Surface Area (BSA) From Baseline 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. |

Absolute Change in 24-hour Urinary Oxalate Corrected for BSA From Baseline 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. |

Secondary |
Percent Change in 24-hour Urinary Oxalate:Creatinine Ratio From Baseline 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. |
Baseline to Month 6 |
|
Secondary |
Percentage of Participants With 24-hour Urinary Oxalate Level Corrected for BSA at or Below 1.5 x ULN at Month 6 |
The upper limit of normal (ULN) = 0.514 mmol/24hr/1.73m^2 for 24-hour urinary oxalate excretion corrected for BSA. |

Secondary |
Percentage of Participants With 24-hour Urinary Oxalate Level Corrected for BSA at or Below ULN at Month 6 |
The upper limit of normal (ULN) = 0.514 mmol/24hr/1.73m^2 for 24-hour urinary oxalate excretion corrected for BSA. |

Secondary |
Percentage Change in Plasma Oxalate From Baseline to Month 6 |
Percent 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. |

Secondary |
Absolute Change in Plasma Oxalate From Baseline to Month 6 |
Absolute 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. |
Baseline to Month 6 |
|
Secondary |
Change in Estimated Glomerular Filtration Rate (eGFR) From Baseline to Week 2 and 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 <18 years of age at screening. Change from baseline to Month 6 is reported. |
