5. Surgical sterilization (bilateral oophorectomy or hysterectomy)
6. Women \<50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatments and if they have luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution or underwent surgical sterilization (bilateral oophorectomy or hysterectomy)
7. Women ≥50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatments, or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy or hysterectomy).
11. Non-sterile males must be willing to use a highly effective method of birth control for the duration of the study treatment and for 4 months after the final dose of cabozantinib.
A sterile male is defined as:
1. One for whom azoospermia has been previously demonstrated in a semen sample examination as definitive evidence of infertility.
2. Males with known "low sperm counts" (consistent with "sub-fertility") are not to be considered sterile for purposes of this study.
12. Capable of understanding and complying with the protocol requirements and signed informed consent.
Exclusion Criteria:
1. Prior treatment with any of the following:
1. Cabozantinib.
2. Selective small-molecule BRAF kinase inhibitor (eg, vemurafenib, dabrafenib).

4. Systemic chemotherapy regimen (given as a single agent or in combination with another chemotherapy agent).
2. Receipt of any type of small molecule kinase inhibitor (including investigational kinase inhibitor) within 2 weeks or 5 half-lives of the agent, whichever is longer, before first dose of study treatment.
3. Receipt of any type of anticancer antibody (including investigational antibody) within 4 weeks before first dose of study treatment.

7. The subject has uncontrolled, significant intercurrent or recent illness including, but not limited to, the following conditions:
a. Cardiovascular disorders: i. Congestive heart failure class 3 or 4 as defined by the New York Heart Association, unstable angina pectoris, serious cardiac arrhythmias.
ii. Uncontrolled hypertension defined as sustained BP \> 150 mm Hg systolic or \> 100 mm Hg diastolic despite optimal antihypertensive treatment.

Complete wound healing from major surgery must have occurred 4 weeks before the first dose of study treatment and from minor surgery (eg, simple excision, tooth extraction) at least 10 days before the first dose of study treatment. Patients with clinically relevant ongoing complications from prior surgery are not eligible.
9. Corrected QT interval calculated by the Fridericia formula (QTcF) \> 500 ms within 28 days before the first dose of study treatment.
Note: If a single ECG shows a QTcF with an absolute value \> 500 ms, two additional ECGs at intervals of approximately 3 min must be performed within 30 min after the initial ECG, and the average of these 3 consecutive results for QTcF will be used to determine eligibility.
