Overview
Brief Summary
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of single-ascending doses (SAD) and multiple-ascending doses (MAD) of lumasiran in healthy adult volunteers and subjects with primary hyperoxaluria type 1 (PH1). In Part A, single ascending dose (SAD) part, healthy adults were dosed with lumasiran or placebo once. In Part B, multiple ascending doses (MAD) part, patients with primary hyperoxaluria type 1 (PH1) were dosed with lumasiran or placebo. All patients that initially received placebo received lumasiran after completing placebo dosing.

Arms & Interventions
Part A: SAD: Placebo
A single dose of matching placebo will be administered subcutaneously (SC).
Intervention: Placebo
Part A: SAD: Lumasiran 0.3 mg/kg
A single dose of 0.3 mg/kg lumasiran will be administered SC.
Intervention: Lumasiran
Part A: SAD: Lumasiran 1.0 mg/kg
A single dose of 1.0 mg/kg lumasiran will be administered SC.
Intervention: Lumasiran
Part A: SAD: Lumasiran 3.0 mg/kg
A single dose of 3.0 mg/kg lumasiran will be administered SC.
Intervention: Lumasiran
Part A: SAD: Lumasiran 6.0 mg/kg
A single dose of 6.0 mg/kg lumasiran will be administered SC.
Intervention: Lumasiran
Part B: MAD: Placebo
Participants with primary hyperoxaluria type 1 (PH1) will be treated with placebo matching one of the lumasiran dosages in the lumasiran arms (one placebo participant for each lumasiran arm). At Day 85 these placebo treated participants will cross over to their respective Part B lumasiran arms in the Part B: MAD Study Day 85-End of Study Period and will then be treated with lumasiran. The estimated total time on study was up to 546 days.
Intervention: Placebo
Part B: MAD: Lumasiran 1.0 mg/kg qM
Participants with PH1 will be treated with 1.0 mg/kg lumasiran SC once monthly (qM) on Days 1, 29 and 57. The estimated total time on study is up to 546 days. One participant from the Part B: MAD: Placebo arm will cross over to this lumasiran arm at Day 85. For this participant treatment with lumasiran starts at Day 85.
Intervention: Lumasiran
Part B: MAD: Lumasiran 3.0 mg/kg qM
Participants with PH1 will be treated with 3.0 mg/kg lumasiran SC qM on Days 1, 29 and 57. The estimated total time on study is up to 546 days. One participant from the Part B: MAD: Placebo arm will cross over to this lumasiran arm at Day 85. For this participant treatment with lumasiran starts at Day 85.
Intervention: Lumasiran
Part B: MAD: Lumasiran 3.0 mg/kg q3M
Participants with PH1 will be treated with 3.0 mg/kg lumasiran SC once every three months (q3M) on Days 1 and 85. The estimated total time on study is up to 546 days. One participant from the Part B: MAD: Placebo arm will cross over to this lumasiran arm at Day 85. For this participant treatment with lumasiran starts at Day 85.
Intervention: Lumasiran
Outcomes
Primary Outcomes
Number of Participants With Adverse Events (AEs)
Time Frame: Part A (SAD): Up to 405 days; Part B (MAD): Up to 546 days
An AE is any untoward medical occurrence in a clinical investigational subject administered a medicinal product and which does not necessarily have a causal relationship with this treatment.
