Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Placebo Comparator: Placebo; Lumasiran-matching placebo (normal saline [0.9% NaCl]) was administered subcutaneously (SC) at Day 1 and Months 1, 2 and 3 during the 6-Month Double-blind (DB) Period, followed by lumasiran SC, 3.0 mg/kg, at Months 6, 7 and 8 during the 3-Month Blinded Treatment Extension Period, followed by lumasiran SC, 3.0 mg/kg, at Month 9 and then every three months during the 51-Month Open-label Extension (OLE) period.	Drug: Placebo; Placebo by SC injection; Drug: Lumasiran; Lumasiran by SC injection; Other Names: ALN-GO1
Experimental: Lumasiran; Lumasiran was administered SC, 3.0 mg/kg, at Day 1 and Months 1, 2 and 3 during the 6-Month DB Period, followed by lumasiran SC, 3.0 mg/kg at Month 6, and lumasiran-matching placebo SC at Months 7 and 8 during the 3-Month Blinded Treatment Extension Period, followed by lumasiran SC, 3.0 mg/kg, at Month 9 and then every three months during the 51-Month OLE period.	Drug: Placebo; Placebo by SC injection; Drug: Lumasiran; Lumasiran by SC injection; Other Names: ALN-GO1

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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.	Baseline to Month 6

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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.	Baseline to Month 6
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
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.	Month 6
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.	Month 6
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.	Baseline to Month 6
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
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.	Baseline, Week 2, Months 1, 2, 3, 4, 5 and 6
Absolute Change in 24-hour Urinary Oxalate Excretion From Baseline Over Time During the Extension Period		Up to 60 months
Percentage Change in 24-hour Urinary Oxalate Excretion From Baseline Over Time During the Extension Period		Up to 60 months
Percentage of Time That 24-hour Urinary Oxalate is at or Below 1.5 × ULN During the Extension Period		Up to 60 months
Change in 24-hour Urinary Oxalate:Creatinine Ratio From Baseline Over Time During the Extension Period		Up to 60 months
Change in Estimated Glomerular Filtration Rate (eGFR) From Baseline Over Time During the Extension Period		Up to 60 months

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
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.	12-Month Period prior to Informed Consent, 6-Month DB Period
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
