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 for patients who received anti-PD-1 or anti-PD-L1 therapy as part of the most recent regimen (either adjuvant monotherapy or first-line in combination with anti-CTLA-4 or VEGFR-TKI), with no more than 1 prior regimen in the metastatic setting.

Inclusion Criteria: * Unresectable and measurable locally advanced or metastatic renal cell carcinoma with a primary clear cell component. * A Karnofsky Performance Status (KPS) score ≥ 80% * At least 1 target lesion measurable by computed tomography/magnetic resonance imaging per RECIST 1.1, not within a field of prior radiation therapy. * Adequate organ and marrow function, ≤ 1 week prior to randomization. * Women of childbearing potential (WOCBP) must have a negative serum pregnancy test. 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. NOTE: Other protocol defined Inclusion/Exclusion criteria may apply.
