Single-Dose Pharmacokinetics of MK-3866 in Participants With Hepatic Impairment (MK-3866-006)

Study Overview
=================
Brief Summary
-----------------
This is an open-label, single-dose, Phase 1 study to evaluate the pharmacokinetics (PK) of intravenous (IV) MK-3866 in participants with moderate and severe hepatic impairment (HI) compared to that of matched healthy participants. The primary purpose of this study is to understand the effect of HI on the plasma PK of MK-3866 in order to guide dosing recommendations for participants with HI. This study will also evaluate the safety and tolerability of MK-3866 in participants with moderate and severe HI.

| Area Under the Concentration-time Curve of MK-3866 From Time 0 to Infinity (AUC0-∞) | AUC0-∞ is determined for the period up to 72 hours post-single dose.
