Participant gender:
All
Summary
This phase II trial studies whether adding radium-223 dichloride to the usual treatment, cabozantinib, improves outcomes in patients with renal cell cancer that has spread to the bone. Radioactive drugs such as radium-223 dichloride may directly target radiation to cancer cells and minimize harm to normal cells. Cabozantinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving radium-223 dichloride and cabozantinib may help lessen the pain and symptoms from renal cell cancer that has spread to the bone, compared to cabozantinib alone.

Criteria
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
>= 14 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 cabozantinb

- 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 registration or receipt of any anti-cancer therapy (including
investigational therapy, monoclonal antibodies, cytokine therapy) within 3 weeks of
registration

- No prior hemibody external radiotherapy

- No prior therapy with radium-223 dichloride or systemic radiotherapy (such as
samarium, strontium)

- No major surgery within 6 weeks of randomization. Procedures such as thoracentesis,
paracentesis, percutaneous biopsy, Moh's or other topical skin surgery, Lasik eye
surgery are not considered major surgery. Patients who have had a nephrectomy may be
registered >= 3 weeks after surgery, providing there are no wound-healing
complications. Subjects with clinically relevant ongoing complications from prior
surgery are not eligible

- Recovery to baseline or =< grade 1 CTCAE version 5.0 from toxicity related to any
prior treatment, unless adverse events are clinically nonsignificant and/or stable on
supportive therapy

- The use of osteoclast targeted therapy including either bisphosphonates or denosumab
is mandated on this study except in patients with contraindications as determined by
the treating investigator, including:

- Hypocalcemia

- Hypophosphatemia

- Renal impairment including those with a glomerular filtration rate (GFR) < 35
mL/min using the Cockcroft-Gault equation or acute renal impairment

- Hypersensitivity to drug formulation

- Dental condition or need for dental intervention that per the investigator
would increase the risk of osteonecrosis of jaw (ONJ).

- Use of osteoclast targeted therapy or reason against use needs to be
recorded in the electronic case report form (eCRF). Additionally, reason for
discontinuation of osteoclast targeted therapy need to be appropriately
documented in the eCRF

- Not pregnant and not nursing, because this study involves an investigational agent
whose genotoxic, mutagenic and teratogenic effects on the developing fetus and newborn
are unknown.

- Therefore, for women of childbearing potential only, a negative urine pregnancy
test done =< 28 days prior to registration is required. A female of childbearing
potential is a sexually mature female who: 1) has not undergone a hysterectomy or
bilateral oophorectomy; or 2) has not been naturally postmenopausal for at least
12 consecutive months (i.e., has had menses at any time in the preceding 12
consecutive months)

- Karnofsky performance status >= 60%

- No brain metastases or cranial epidural disease unless adequately treated with
radiotherapy, radiosurgery, or surgery and stable for at least 4 weeks prior to
registration as documented by MRI or CT imaging or deemed stable by clinical
investigator. Treated brain metastases are defined as having no ongoing requirement
for steroids and no evidence of progression or hemorrhage after treatment for at least
4 weeks prior to registration as documented by MRI or CT imaging or deemed stable by
clinical investigator

- No imminent or established spinal cord compression based on clinical symptoms 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 2
weeks before registration

- No imminent or impending pathologic fracture based on clinical symptoms and/or
imaging. In patients with untreated imminent or impending pathologic fracture,
treatment with standard of care as clinically indicated should be completed at least 2
weeks before registration

- No significant, uncontrolled intercurrent or recent illness, including but not limited
to the following conditions:

- Cardiovascular disorders: Symptomatic congestive heart failure, unstable angina
pectoris, serious cardiac arrhythmia; uncontrolled hypertension defined as
sustained blood pressure > 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 6 months before
randomization; thromboembolic event (e.g., deep venous thrombosis, pulmonary
embolism) within 1 month before randomization; screening Fridericia's correction
formula (QTcF) =< 500 msec

- Gastrointestinal disorders: Disorders associated with a high risk of perforation
or fistula formation: active inflammatory bowel disease, active diverticulitis,
active cholecystitis, active symptomatic cholangitis or active appendicitis,
active acute pancreatitis or active acute obstruction of the pancreatic or
biliary duct, or active gastric outlet obstruction; abdominal fistula,
gastrointestinal perforation, bowel obstruction, or intra-abdominal abscess
within 3 months before randomization. Note: Complete healing of an
intra-abdominal abscess must be confirmed before randomization

- No clinically significant hematuria, hematemesis, or hemoptysis, or other history
of significant bleeding (e.g., pulmonary hemorrhage) within 3 months before
randomization

- No lesions invading major pulmonary blood vessels

- No other clinically significant disorders:

- For patients with evidence of chronic hepatitis B virus (HBV) infection, the
HBV viral load must be undetectable on suppressive therapy (with no
medications prohibited by this protocol [e.g. drug-drug interactions]), if
indicated

- Patients with a history of hepatitis C virus (HCV) infection must have been
treated and cured. For patients with HCV infection who are currently on

a frequently updated medical reference. Patients may not have received a strong CYP3A4
inducer within 12 days prior to registration nor a strong CYP3A4 inhibitor within 7
days prior to registration

- No concomitant anticoagulation with coumarin agents (e.g., warfarin), direct thrombin
inhibitors (e.g., dabigatran), direct factor Xa inhibitor betrixaban, or platelet
