Pharmacology
Axitinib is a selective inhibitor of receptor tyrosine kinases including VEGFR-1, VEGFR-2, and VEGFR-3, which are implicated in pathologic angiogenesis, tumor growth, and cancer progression; VEGF-mediated endothelial cell proliferation and survival were inhibited by axitinib in vitro and in mouse models.
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.
