A Study of Bomedemstat (MK-3543) in Participants With Mild or Moderate Hepatic Impairment (MK-3543-023)

Study overview

The purpose of this study is to learn what happens to bomedemstat (MK-3543) in a person's body over time. Researchers will compare what happens to bomedemstat in the body when it is given to participants with mild or moderate hepatic (liver) impairment and healthy participants. Participants will be allocated to one of three groups: mild hepatic impairment (HI), moderate HI, or healthy matched control. All participants will receive a single oral dose of bomedemstat on Day 1. Healthy control participants will be enrolled after hepatic impairment participants have been dosed. Healthy control participants will be matched for the mean age and mean body-mass index (BMI) of all participants with HI (mild and moderate HI combined) and sex to each HI group separately.

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
