Brief Summary:

The goal of this clinical research study is to compare the safety and effectiveness of cabozantinib and sunitinib when given to patients with metastatic (has spread) variant histology renal cell carcinoma (vhRCC), a type of kidney cancer.

This is an investigational study. Cabozantinib and sunitinib are both FDA approved and commercially available for the treatment of advanced kidney cancer, including vhRCC.

The study doctor can explain how the study drugs are designed to work.

Up to 84 participants will be enrolled in this study. All will take part at MD Anderson.

Primary Outcome Measures :
  1. Progression-Free Survival (PFS) Evaluated Using RECIST 1.1 Criteria [ Time Frame: From randomization up to the time of disease progression or death up to two years ]
    PFS defined as the time from randomization to progression or death, regardless of cause, whichever comes first.

Secondary Outcome Measures :
  1. Objective Response Rate (ORR) Evaluated Using RECIST 1.1 Criteria [ Time Frame: From randomization up to the time of disease progression or death up to two years ]
    ORR is the best response recorded from the start of treatment until disease progression/recurrence (taking into consideration confirmation of response and reference for progressive disease the smallest measurements recorded since the treatment started).

  2. Overall Survival (OS) [ Time Frame: From randomization to death or last contact if still alive up to two years ]
    OS defined as the time from randomization to death or last contact if still alive.

  3. Adverse Event Rates [ Time Frame: Start of study drug up to 30 days after last dose of study drug ]
    Adverse events recorded by CTCAE version 4.0

  1. The subject has a histologic or cytologic diagnosis of a variant histology renal cell carcinoma including papillary, chromophobe, Xp.11 translocation, undifferentiated, or unclassified which is treatment naïve or has previously been treated with one systemic treatment line not containing any vascular endothelial growth factor antibody or vascular endothelial growth factor receptor tyrosine kinase inhibitors. The patient may have received treatment with immune checkpoint therapy including nivolumab as a single agent or nivolumab plus ipilimumab in combination. Previous treatment with mammalian target of rapamycin agents such as temsirolimus or everolimus is acceptable.
  2. Measurable disease per RECIST v1.1 as determined by the investigator.
  3. The subject has had an assessment of all known disease sites eg, by computerized tomography (CT) scan, magnetic resonance imaging (MRI), bone scan as appropriate, within 28 days before the first dose of cabozantinib or sunitinib.
  4. The subject is >/=18 years old on the day of consent;
  5. The subject has an Eastern Cooperative Oncology Group (ECOG) performance status of </=2.
  6. Recovery to baseline or </= Grade 1 CTCAE v.4.0 from toxicities related to any prior treatments, unless AE(s) are clinically nonsignificant and/or stable on supportive therapy;
  7. The subject has organ and marrow function and laboratory values as follows within 4 days before the first dose of cabozantinib or sunitinib: a.The ANC >/= 1500/mm^3 without colony stimulating factor support; b.White blood cell count >/= 2500/mm^3 (>/= 2.5 GI/L). c.Platelets >/=100,000/mm^3; d.Hemoglobin >/= 9 g/dL; e. Bilirubin </= 1.5 x the ULN. For subjects with known Gilbert's disease, bilirubin </= 3.0 mg/dL; f.Serum albumin >/= 2.8 g/dl g.Serum creatinine </= 2.0 X ULN or calculated creatinine clearance >/= 30 mL/min (>/= 0.5 mL/sec) using the Cockcroft-Gault equation: Males: (140 - age) x weight (kg)/(serum creatinine [mg/dL] × 72) Females: [(140 - age) x weight (kg)/(serum creatinine [mg/dL] × 72)] × 0.85 h.Alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) </= 3 X upper limit of normal (ULN). ALP </= 5 X ULN with documented bone metastases. i.Urine protein/creatinine ratio (UPCR) </= 1 mg/mg (</= 113.2 mg/mmol);
  8. The subject is capable of understanding and complying with the protocol requirements and has signed the informed consent document;
  9. Sexually active subjects (men and women) must agree to use medically accepted barrier methods of contraception (eg, male or female condom) during the course of the study and for 4 months after the last dose of study drug(s), even if oral contraceptives are also used. All subjects of reproductive potential must agree to use both a barrier method and a second method of birth control during the course of the study and for 4 months after the last dose of study drug(s);
  10. Female subjects of childbearing potential must not be pregnant at screening. Females of childbearing potential are defined as premenopausal females capable of becoming pregnant (ie, females who have had any evidence of menses in the past 12 months, with the exception of those who had prior hysterectomy). However, women who have been amenorrheic for 12 or more months are still considered to be of childbearing potential if the amenorrhea is possibly due to prior chemotherapy, antiestrogens, low body weight, ovarian suppression or other reasons.
