Testing the Addition of a New Anti-cancer Drug, Radium-223 Dichloride, to the Usual Treatment (Cabozantinib) for Advanced Renal Cell Cancer That Has Spread to the Bone, RadiCaL Study

Inclusion Criteria: * Documented histologic or cytologic diagnosis of renal cell cancer (RCC). All subtypes of RCC are eligible including but not limited to clear cell, papillary, chromophobe, translocation, collecting duct carcinoma, medullary carcinoma, and unclassified categories. Enrollment of non-clear cell patients will be limited to 20% of the total sample size (\~ 42 patients). Once this goal is met, accrual of non-clear cell patients will be discontinued (a notice will be sent out 2 weeks in advance). Sarcomatoid and rhabdoid differentiation are allowed * Presence of at least 1 metastatic bone lesion not treated with prior radiation is required. * The presence of bone metastases can be detected by computed tomography (CT), magnetic resonance imaging (MRI), Tc-99m bone scan or positron emission tomography (PET) (fludeoxyglucose F-18 \[FDG\] or sodium fluoride \[NaF\]) imaging. Patients with non-measurable bone-only disease are allowed. Patients may have received prior radiation therapy for bone metastases or other external radiation \>= 7 days prior to registration, as long as they still have at least 1 metastatic bone lesion not treated with radiation. Patients with visceral metastases are allowed, as long as they have at least one untreated bone metastases * No prior treatment with cabozantinib * No treatment with any type of small molecular kinase inhibitor (including investigational kinase inhibitors) within 2 weeks or 5 half-lives (whichever is shorter) of re…
