About

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.
