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.
