This study is researching an experimental drug called ALN-APOC3 (called "study drug"). The study is focused on participants who have dyslipidemia (abnormal amounts of fats in the blood, including triglycerides and cholesterol), but who are otherwise healthy.
The aim of the study is to see how safe and effective the study drug is.
The study is looking at several other research questions, including:
* What side effects may happen from taking the study drug
* How much study drug is in the blood at different times
* How the study drug changes lipid levels in the blood
