Indications
- Von Hippel-Lindau Syndrome
- Renal Cell Carcinoma
- Pheochromocytoma
- Paraganglioma
- Renal Cell Carcinoma
Dosing
Von Hippel-Lindau Syndrome Adults: 120 mg orally once daily. Pediatric patients >=12 years: 120 mg orally once daily if >=40 kg or 80 mg orally once daily if <40 kg.
Renal Cell Carcinoma Adults: 120 mg orally once daily.
Pheochromocytoma Adults: 120 mg orally once daily. Pediatric patients >=12 years: 120 mg orally once daily if >=40 kg or 80 mg orally once daily if <40 kg.
Paraganglioma Adults: 120 mg orally once daily. Pediatric patients >=12 years: 120 mg orally once daily if >=40 kg or 80 mg orally once daily if <40 kg.
Advanced Renal Cell Carcinoma 25 mg administered as an intravenous infusion over a 30-60 minute period once weekly; continue until disease progression or unacceptable toxicity. Premedicate with IV diphenhydramine 25-50 mg approximately 30 minutes before each dose.
Dose Modification - Hepatic Impairment Reduce dose to 15 mg/week in patients with mild hepatic impairment (bilirubin >1-1.5x ULN or AST >ULN but bilirubin <=ULN); contraindicated if bilirubin >1.5x ULN.
Dose Modification - Strong CYP3A4 Inhibitors Avoid concomitant use; if unavoidable, reduce dose to 12.5 mg/week and allow approximately 1-week washout after inhibitor discontinuation before returning to prior dose.
Dose Modification - Strong CYP3A4 Inducers Avoid concomitant use; if unavoidable, increase dose from 25 mg/week up to 50 mg/week, then return to prior dose once inducer is discontinued.
Dose Modification - Toxicity Hold for ANC or platelet nadirs meeting threshold criteria or NCI CTCAE grade >=3 adverse reactions; once resolved to grade <=2, restart at dose reduced by 5 mg/week to no lower than 15 mg/week.
Contraindications

Pharmacology
Belzutifan is a hypoxia-inducible factor-2 alpha (HIF-2α) inhibitor that binds to HIF-2α and blocks its interaction with HIF-1β, leading to reduced transcription of HIF-2α target genes associated with cellular proliferation, angiogenesis, and tumor growth.
Temsirolimus binds to the intracellular protein FKBP-12, and the resulting protein-drug complex inhibits mTOR (mammalian target of rapamycin), blocking its ability to phosphorylate downstream effectors p70S6k and S6 ribosomal protein, leading to G1 growth arrest in tumor cells and reduced levels of HIF-1, HIF-2 alpha, and vascular endothelial growth factor.
