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.
SecondaryPercentage of Time That 24-hour Urinary Oxalate is at or Below 1.5 × ULN During Lumasiran TreatmentUp to Month 60The upper limit of normal (ULN) = 0.514 mmol/24hr/1.73m\^2 for 24-hour urinary oxalate excretion corrected for BSA.
SecondaryAbsolute Change in 24-hour Urinary Oxalate:Creatinine Ratio From Baseline in the Extension PeriodFrom Baseline to Month 54 and Month 60
Absolute change in 24-hour urinary oxalate:creatinine ratio was estimated by an average absolute change from baseline to the end of the OLE period at Month 54 and Month 60. A negative change from Baseline indicates a favorable outcome.
SecondaryChange in Estimated Glomerular Filtration Rate (eGFR) From Baseline in the Extension PeriodFrom Baseline to Month 54 and Month 60
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.
SecondaryNumber of Participants With Treatment Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)
DB Period (Placebo): From first dose of study drug (Day 1) up to Month 6; Placebo/Lumasiran: From first dose of lumasiran (Month 6) up to end of study (Month 60); Lumasiran/Lumasiran: From first dose of lumasiran (Day 1) up to end of study (Month 60).
An AE is any untoward medical occurrence in a clinical investigational participant administered a medicinal product \& which does not necessarily have a causal relationship with this treatment. SAE is any untoward medical occurrence that at any dose results in death, is life-threatening, requires in-patient hospitalization/prolongation of existing hospitalization, results in persistent/significant disability or incapacity, is a congenital anomaly or birth defect, is an important medical event that may not be immediately life-threatening/result in death/hospitalization but may jeopardize the participant \& may require intervention to prevent one of the other outcomes listed above. All Lumasiran Treated Set: All participants who received any amount of lumasiran including participants who took lumasiran during 6-month double-blinded period \& participants who initially took placebo during the 6-month double-blinded period and then switched to lumasiran during the extension period.
OtherRate of Renal Stone Events12-Month Period prior to Informed Consent, 6-Month DB Period
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.
OtherChange From Baseline in Nephrocalcinosis as Assessed by Renal UltrasoundBaseline, Month 6
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.
