Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Has a histologically-confirmed diagnosis of unresectable, locally advanced/metastatic RCC with clear cell component (with or without sarcomatoid features) (may include participants with a diagnosis of von Hippel-Lindau [VHL] associated ccRCC).

Outcomes

Primary Outcome Measures

Percentage of Participants Who Experience at Least One 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. The percentage of participants who experience at least one AE will be reported.
Percentage 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. The percentage of participants who discontinue study treatment due to an AE will be reported.
Percentage of Participants Who Modify or Interrupt 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. The percentage of participants who modify or interrupt study treatment due to an AE will be reported.
Percentage of Participants Who Experience at Least One Dose-limiting Toxicity (DLT)
A DLT consists of one or more of the following toxicities: (1) Grade 3 or 4 hypoxia or dyspnea (2) Grade 3 or 4 nausea, vomiting, or diarrhea if persistent for >48 hours despite therapy (3) Grade 3 or 4 cardiovascular, vascular, or thrombotic events (4) Nonhematologic AE ≥Grade 3 in severity (5) Grade 4 nonhematologic toxicity (6) Grade 3 or 4 hematologic toxicities (7) Grade 3 or 4 febrile neutropenia (8) Grade 3 or 4 nonhematologic laboratory value (9) >2 weeks delay in dosing due to intervention-related toxicity (10) Intervention-related toxicity causing intervention discontinuation in the first 21 days of dosing (11) Missing >20% of belzutifan doses due to drug-related AEs in the first 21 days. (12) Grade 5 toxicity. The percentage of participants who experience at least one DLT will be reported.

Secondary Outcome Measures

Area Under the Plasma Concentration Time Curve (AUC) of Belzutifan
AUC is a measure of plasma drug concentration and time and is estimated as the area under the plot of plasma concentration against time after belzutifan administration. Blood samples collected pre dose and at multiple timepoints post dose will be used to determine AUC.
Maximum Observed Plasma Concentration (Cmax) of Belzutifan
Cmax is the maximum concentration of belzutifan observed in plasma. Blood samples collected pre dose and at multiple timepoints post dose will be used to determine Cmax.
Minimum Observed Plasma Concentration (Cmin) of Belzutifan
Cmin is the minimum concentration of belzutifan observed in plasma after its administration and just prior to administration of a subsequent dose. Blood samples collected pre dose and at multiple timepoints post dose will be used to determine Cmin.
