Previous studies have demonstrated that hypoxia-inducible factor 2α (HIF-2α) is a key oncogenic driver in clear cell renal cell carcinoma (ccRCC). PT2385 was the first reported HIF-2α inhibitor. However, PT2385 was restricted by variable and dose-limited pharmacokinetics. This results from extensive metabolism of PT2385 to its glucuronide metabolite. Herein,...
