Inclusion Criteria:

- Age ≥ 18 years.

limited to clear cell, papillary, chromophobe, collecting duct carcinoma, medullary
carcinoma, and unclassified categories. Sarcomatoid and rhabdoid differentiation are
allowed.

- Presence of at least one metastatic bone lesion(s). Patients with non-measurable
bone-only disease are allowed.

- ECOG performance status of 0-2 (Appendix A).

- Must have adequate organ and bone marrow function.

- Absolute neutrophil count (ANC) ≥ 1500/mm3 (without use of G-CSF 4 weeks prior to
enrollment).

- Platelet count ≥100,000/mm3.

- Hemoglobin ≥ 9 g/dL (transfusions allowed).

- ALT and AST ≤ 3.0 x the upper limit of normal (ULN).

- Total bilirubin ≤ 1.5 x ULN. For participants with Gilbert's disease ≤ 3.0 mg/dL.

- Calculated creatinine clearance ≥ 30 mL/min using the Cockroft-gault equation.

- Urine protein-to-creatinine (UPC) ratio ≤ 2 mg/mg creatinine or 24-hour urine
protein < 2 g.

- Recovery to baseline or ≤ grade 1 CTCAE version 4.0 from toxicities related to any
prior treatment, unless adverse events are clinically non-significant and/or stable on
supportive therapy.

- Capable of understanding and complying with the protocol requirements and has signed
the informed consent document.

- Sexually active participants and their partners must agree to use medically accepted
methods of contraception.

- Female participants of childbearing potential must not be pregnant at screening.

- Sexually active participants (men and women) must agree to use highly effective
contraceptive methods during the course of the study and for 6 months after completing
treatment with radium-223.

Exclusion Criteria:

- For patients in the sorafenib cohort, no prior therapy with sorafenib is allowed and
at least 1 line of prior therapy is required including prior: VEGF-targeting therapy
(such as sunitinib, axitinib, tivozanib, bevacizumab), mTOR-targeting therapy (such as
everolimus, temsirolimus), immunotherapy (such as anti-PD-1 or anti-PD-L1), cytokine
therapy (such as interleukin-2, IFN-a) or cytotoxic systemic chemotherapy allowed.

- For patients in the pazopanib cohort, no prior systemic therapy for mRCC is allowed,
with the exception of prior cytokine therapy (such as interleukin-2, IFN-a),
immunotherapy (such as anti-PD-1 or anti-PD-L1), or supportive therapies (such as
zoledronic acid, denosumab).

- Receipt of any type of small molecular kinase inhibitor (including investigational
kinase inhibitors) within 2 weeks of enrollment or receipt of any anti-cancer therapy
(including investigational therapy, monoclonal antibodies, cytokine therapy) within 3
weeks of enrollment.

- Radiation therapy for bone metastases within 2 weeks, other external radiation therapy
within 4 weeks of enrollment.

- Received prior hemibody external radiotherapy.

- Prior therapy with radium-223 or systemic radiotherapy (such as samarium, strontium).

- Known brain metastases or cranial epidural disease unless adequately treated with
radiotherapy, radiosurgery, or surgery and stable for at least 4 weeks of enrollment
as documented by MRI or CT imaging. Treated brain metastases are defined as having no
ongoing requirement for steroids (must be off steroids for at least 4 weeks) and no
evidence of progression or hemorrhage after treatment for at least 4 weeks of
enrollment as documented by MRI or CT imaging.

- Imminent or established spinal cord compression based on clinical and/or imaging. In
patients with untreated imminent or established spinal cord compression, treatment
with standard of care as clinically indicated should be completed at least 4 weeks
before enrollment.

- The subject has uncontrolled, significant intercurrent or recent illness including,
but not limited to, the following conditions:

- Cardiovascular disorders:

- Symptomatic congestive heart failure, unstable angina pectoris, serious
cardiac arrhythmias.

- uncontrolled hypertension defined as sustained BP > 150 mm Hg systolic or >
100 mm Hg diastolic despite optimal antihypertensive treatment.

- Stroke (including transient ischemic attack), myocardial infarction, or
other ischemic event within 12 weeks of enrollment.

- Thromboembolic event (such as deep venous thrombosis, pulmonary embolism)
within 4 weeks of enrollment.

- GI disorders including those associated with a high risk of perforation or
fistula formation:

- Tumors invading the GI-tract, active peptic ulcer disease, inflammatory
bowel disease, diverticulitis, cholecystitis, symptomatic cholangitis or
appendicitis, acute pancreatitis or acute obstruction of the pancreatic or
biliary duct, or gastric outlet obstruction.

- Abdominal fistula, gastrointestinal perforation, bowel obstruction, or
intraabdominal abscess within 12 weeks before enrollment. Note: Complete
healing of an intra-abdominal abscess must be confirmed before enrollment.

- Clinically significant hematuria, hematemesis, or hemoptysis of > 0.5 teaspoon
(2.5 ml) of red blood, or other history of significant bleeding (such as
pulmonary hemorrhage) within 4 weeks of enrollment.

- Other clinically significant disorders such as:

- Active infection requiring systemic treatment, infection with human
immunodeficiency virus (HIV) or acquired immunodeficiency syndrome
(AIDS)-related illness, or chronic hepatitis B or C infection.

- Serious non-healing wound or ulcer.

- Malabsorption syndrome.

- Symptomatic hypothyroidism.

- Moderate to severe hepatic impairment (Child-Pugh B or C).

- Requirement for hemodialysis or peritoneal dialysis.

- History of solid organ transplantation.

- Major surgery (such as GI surgery) within 6 weeks of enrollment. However,
subjects who have had a nephrectomy may be enrolled 4 weeks after surgery,
providing there are no wound-healing complications. Subjects with clinically
relevant ongoing complications from prior surgery are not eligible. The following
are not considered to be major procedures: Thoracentesis, paracentesis, port
placement, laparoscopy, thoracoscopy, bronchoscopy, endoscopic ultrasonographic
procedures, mediastinoscopy, skin biopsies, incisional biopsies, imaging-guided
biopsy for diagnostic purposes, and routine dental procedures.

- QTcF > 470 msec within 4 weeks of enrollment. If the initial QTcF is found to be
> 470 ms, two additional EKGs separated by at least 3 minutes should be
performed. If the average of these three consecutive results for QTcF is ≤ 470
ms, the subject meets eligibility in this regard.

- Pregnant or lactating females.

- Inability to swallow tablets or capsules.

- Previously identified allergy or hypersensitivity to components of the study
treatment formulations.

- Diagnosis of another malignancy within 2 years of enrollment, except for
superficial skin cancers, or localized, low grade tumors deemed cured and not
treated with systemic therapy by the principal investigator
