Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage Change in Spot Urinary Oxalate:Creatinine Ratio From Baseline to Month 6	Percent change in spot urinary oxalate:creatinine 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 Change in Urinary Oxalate Excretion From Baseline to End of Study (Month 60)		Up to 60 months
Secondary	Absolute Change in Urinary Oxalate Excretion From Baseline		Up to 60 months
Secondary	Percentage of Time That Spot Urinary Oxalate:Creatinine Ratio = Near-normalization Threshold (=1.5 × ULN)		Up to 60 months
Secondary	Percentage of Participants With Urinary Oxalate Excretion = the Upper Limit of Normal (ULN) and = 1.5 x ULN		Up to 60 months
Secondary	Percentage Change in Plasma Oxalate From Baseline to End of Study (Month 60)		Up to 60 months
Secondary	Absolute Change in Plasma Oxalate From Baseline to End of Study (Month 60)		Up to 60 months
Secondary	Maximum Observed Plasma Concentration (Cmax) of Lumasiran		Up to 24 months
Secondary	Time to Maximum Observed Plasma Concentration (Tmax) of Lumasiran		Up to 24 months
Secondary	Elimination Half-life (t1/2beta) of Lumasiran		Up to 24 months
Secondary	Area Under the Concentration-time Curve (AUC) of Lumasiran		Up to 24 months
Secondary	Apparent Clearance (CL/F) of Lumasiran		Up to 24 months
Secondary	Apparent Volume of Distribution (V/F) of Lumasiran		Up to 24 months
Secondary	Change in Estimated Glomerular Filtration Rate (eGFR) From Baseline		Up to 60 months
Secondary	Frequency of Adverse Events (AEs)		Up to 60 months
