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.
Bevacizumab-bvzr binds VEGF and prevents its interaction with receptors Flt-1 and KDR on the surface of endothelial cells, inhibiting endothelial cell proliferation, new blood vessel formation, and metastatic disease progression.
