Drug Facts

ClassHIF-2α inhibitor
MechanismSelective small-molecule inhibitor of hypoxia-inducible factor 2α (HIF-2α). VHL inactivation (somatic in ~90% of clear-cell RCC, germline in von Hippel-Lindau syndrome) → HIF-2α stabilization → drives the angiogenic/glycolytic ccRCC phenotype. Belzutifan disrupts HIF-2α heterodimerization with HIF-1β, suppressing the downstream transcriptional programme.
Typical dosing120 mg PO once daily, continuous, until progression or unacceptable toxicity. Hemoglobin and oxygen-saturation monitoring at baseline + every cycle — anemia + hypoxia are class-defining ON-target effects (HIF-2α regulates EPO).

Notes

First-in-class HIF-2α inhibitor; mechanism-of-action drug for VHL-syndrome-associated tumors. In sporadic ccRCC, used 2L+ after PD-(L)1 + VEGF-TKI. Reduces hemangioblastoma volume and pancreatic NET volume in VHL syndrome — surgery-sparing in many cases. UA-access is the bottleneck; document pathway in AccessPathway entity once Phase D content lands.
