Refractory Clear Cell Renal Cell Carcinoma

This is a single-institution, pilot study of oral casdatifan, a selective HIF-2α inhibitor, in patients with metastatic clear cell renal cell carcinoma refractory to prior IO- and VEGF-based therapies. This phase I trial evaluates the effects of casdatifan on certain genes linked to kidney cancer growth and tests it for the treatment of clear cell renal cell cancer that has not responded to previous treatment (refractory) and that has spread from where it first started (primary site) to other places in the body (metastatic). Casdatifan may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
