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.
