Long considered undruggable, hypoxia-inducible factor 2α (HIF2α) has now been validated as a therapeutic target in several cancers. This Review discusses the structural basis for HIF2α druggability, the clinical results to date and key challenges, including toxicities and the need for predictive biomarkers, as well as emerging targeting modalities and combination strategies that might enhance efficacy, overcome resistance and broaden indications for HIF2 inhibition.
