Medically controlled arrhythmia stable on medication is permitted. - Has moderate to severe hepatic impairment. - Has an active infection requiring therapy (includes tuberculosis). - Has known human immunodeficiency virus (HIV) and/or hepatitis B or C infections or is known to be positive for hepatitis B surface antigen (HBsAg)/hepatitis B virus (HBV) deoxy ribonucleic acid (DNA) or hepatitis C antibody or ribonucleic acid (RNA). - Has a history or current evidence of a gastrointestinal (GI) condition (eg, inflammatory bowel disease, Crohn's disease, ulcerative colitis) or impaired liver function. - Has had major surgery ≤3 weeks prior to first dose of study intervention. - Has received prior treatment with belzutifan. - Has received any type of systemic anticancer antibody (including investigational antibody) ≤4 weeks prior to the first dose of study intervention. - Has recovered from all AEs due to previous therapies to ≤ Grade 1 or baseline. Participants with a ≤ Grade 2 neuropathy may be eligible. - Has received prior radiotherapy within 2 weeks prior to randomization. - Has received colony-stimulating factors (CSFs) (e.g., granulocyte-CSF [G-CSF], granulocyte monocyte-CSF [GM-CSF] or recombinant erythropoietin [EPO]) ≤28 days prior to the first dose of study intervention. - Has participated and received study intervention in a study of an investigational agent or has used an investigational device within 4 weeks prior to the first dose of study intervention. Note: Participants who have entered the follow-up phase of an investigational study may participate as long as it has been at least 4 weeks since the last dose of the previous investigational agent.
