Study of Casdatifan and Cabozantinib Versus Placebo and Cabozantinib in Patients With Advanced Clear Cell Renal Cell Carcinoma

The purpose of the study is to evaluate the progression-free survival (PFS) of casdatifan versus placebo when each is given in combination with cabozantinib in adult patients with confirmed advanced or metastatic clear cell Renal Cell Carcinoma who have experienced progression on or after prior anti-PD-1 or anti-PD-L1 immunotherapy.

Exclusion Criteria: * Received prior treatment with a HIF-2α inhibitor or cabozantinib. * Other prior malignancy active within the previous year except for locally curable cancers that have been apparently cured. * Ongoing clinically significant toxicities related to any prior anticancer treatment, or toxicities Grade ≥ 3 per National Cancer Institute Common Terminology Criteria for Adverse Events, version 5.0 (NCI CTCAE v5.0) regardless of relatedness to prior anticancer therapies. * Uncontrolled or poorly controlled hypertension, defined as a sustained blood pressure \> 150 mmHg systolic or \> 90 mmHg diastolic despite optimal antihypertensive treatment. * History of leptomeningeal disease or spinal cord compression.
