The primary purpose of this study is to compare the plasma pharmacokinetics (PK) of belzutifan (MK-6482) following a single oral 80 mg dose of belzutifan in participants with moderate hepatic impairment to that of healthy matched control participants. This study will also evaluate the safety and tolerability of a single oral 80 mg dose of belzutifan in participants with moderate hepatic impairment.

Area Under the Concentration-Time Curve From Time 0 to Infinity (AUC0-Inf) of Belzutifan
AUC0-Inf was defined as the area under the concentration-time curve of belzutifan from time zero to infinity. Blood samples collected predose and at multiple timepoints postdose were used to determine AUC0-Inf of belzutifan.
Time frame: Predose and at 0.5, 1, 1.5, 2, 3, 4, 5, 6, 9, 12, 24, 36, 48, 72, 96, and 120 hours postdose
Area Under the Concentration-Time Curve From Time 0 to 24 Hours (AUC0-24hrs) of Belzutifan
AUC0-24hrs was defined as the area under the concentration-time curve of belzutifan from time zero to 24 hours postdose. Blood samples collected predose and at multiple timepoints postdose were used to determine AUC0 to 24 hours of belzutifan.
Time frame: Predose and at 0.5, 1, 1.5, 2, 3, 4, 5, 6, 9, 12, 24 hours postdose
Maximum Plasma Concentration (Cmax) of Belzutifan
Cmax was defined as the peak level belzutifan reaches in the blood. Blood samples collected predose and at multiple timepoints postdose were used to determine Cmax of belzutifan.
Time frame: Predose and at 0.5, 1, 1.5, 2, 3, 4, 5, 6, 9, 12, 24, 36, 48, 72, 96, and 120 hours postdose
Time to Maximum Plasma Concentration (Tmax) of Belzutifan
Tmax was defined as the time it took belzutifan to reach its peak level in the blood. Blood samples collected predose and at multiple timepoints postdose were used to determine the Tmax of belzutifan.
Time frame: Predose and at 0.5, 1, 1.5, 2, 3, 4, 5, 6, 9, 12, 24, 36, 48, 72, 96, and 120 hours postdose
Apparent Terminal Half-life (t1/2) of Belzutifan
Apparent terminal half-life (t1/2) was defined as the time needed to reduce the level of belzutifan in the blood by one-half (1/2). Blood samples collected predose and at multiple timepoints postdose were used to determine the apparent terminal half-life (t1/2) of belzutifan.
Time frame: Predose and at 0.5, 1, 1.5, 2, 3, 4, 5, 6, 9, 12, 24, 36, 48, 72, 96, and 120 hours postdose

Number of Participants Who Experience an Adverse Event (AE)
An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. The number of participants who experienced an AE is reported.
Time frame: Up to 15 days
Number of Participants Who Discontinue Study Treatment Due to an AE
An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. The number of participants who discontinued the study due to an AE is reported.
Time frame: Up to 15 days
