Brief summary: This research study is evaluating a drug called cabozantinib as a possible treatment cancer of the bile duct. Cabozantinib is a drug that targets specific pathways inside the cells of the body. By blocking the c-MET and VEGFR2 pathways from sending signals, cabozantinib may prevent cells from multiplying. This drug has been used in other research studies and information from those other research studies suggests that this drug may help to stop the growth of bile duct cancer.

In this research study, the investigators are looking to see how well cabozantinib works in slowing the growth of bile duct cancer. The investigators are also assessing the safety and tolerability of cabozantinib in participants with this type of cancer.

Detailed description: After the screening procedures confirm that the participants are eligible to participate in the research study:

A two-stage design will be employed in this study where at least 9 of the 20 patients enrolled in the first stage need to be progression-free at 16 weeks before the second stage can proceed. If this criterion is met, an additional 24 patients will be enrolled in the second stage for a total of 44 patients in the study. Patients will be treated with cabozantinib 60 mg daily administered orally continuously for 28-day cycles. Tumor assessments will be performed every 8 weeks until documented disease progression by RECIST criteria or drug intolerance.

In this research study, the participant will be given a study drug-dosing diary for each treatment cycle. Each treatment cycle lasts 28 days (4 weeks), during which time the participant will be taking the study drug, cabozantinib daily. The diary will also include special instructions for taking the study drug(s).

The participant will continue to take cabozantinib for as long as it is tolerated without any unacceptable side effects and the cancer does not get worse.

The following tests and procedures will be done during the research study:

Cycle 1 - On days 1, 8 and 15

* Medical History
* Physical Exam including vital signs and height and weight

* Women of childbearing potential must have a negative pregnancy test at screening. Women of childbearing potential include women who have experienced menarche and who have not undergone successful surgical sterilization (hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or are not postmenopausal. Postmenopause is defined as amenorrhea ≥ 12 consecutive months. Note: 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, ovarian suppression or any other reversible reason.

* Other clinically significant disorders such as:
* active infection requiring systemic treatment within 28 days before the first dose of study treatment
* serious non-healing wound/ulcer/bone fracture within 28 days before the first dose of study treatment
* history of organ transplant
* concurrent uncompensated hypothyroidism or thyroid dysfunction within 7 days before the first dose of study treatment
* history of major surgery as follows:
* Major surgery within 3 months of the first dose of cabozantinib if there were no wound healing complications or within 6 months of the first dose of cabozantinib if there were wound complications

* Psychiatric illness/social situations that would limit compliance with study requirements.
* The subject has a history of clinically significant hematemesis, hemoptysis of \> 2.5 mL of red blood, radiation (including brachytherapy) to pulmonary lesions, or signs indicative of significant pulmonary hemorrhage within 3 months before the first dose of study treatment.
* The subject has radiographic evidence of cavitating pulmonary lesion(s)
* The subject has a lesion abutting, invading, or encasing a major blood vessel.
* The subject has evidence of tumor invading the GI tract (esophagus, stomach, small or large bowel, rectum or anus), or any evidence of endotracheal or endobronchial tumor within 28 days before the first dose of cabozantinib.
* The subject has received any other type of investigational agent within 28 days before the first dose of study treatment.
* The subject has a corrected QT interval calculated by the Fridericia formula (QTcF) \>500 ms within 28 days before randomization. . Note: if initial QTcF is found to be \> 500 ms, two additional EKGs separated by at least 3 minutes should be performed. If the average of these three consecutive results for QTcF is ≤ 500 ms, the subject meets eligibility in this regard
* History of allergic reactions attributed to compounds of similar chemical or biologic composition to cabozantinib.
* The subject requires concomitant treatment, in therapeutic doses, with anticoagulants such as warfarin, warafarin-related agents, heparin, thrombin inhibitors, Factor Xa inhibitors, or antiplatelet agents (eg, clopidogrel). Low dose aspirin (≤ 81 mg/day), low-dose warfarin (≤ 1 mg/day), and prophylactic Low Molecular Weight Heparin (LMWH) are permitted.
* The subject requires concomitant use of strong CYP3A4 inducers (eg, dexamethasone, phenytoin, carbamazepine, rifampin, rifabutin, rifapentin, phenobarbital, and St. John's Wort) or strong CYP3A4 inhibitors (eg, ketoconazole, itraconazole, clarithromycin, indinavir, nefazodone, nelfinavir, and ritonavir).
* The subject has received prior treatment with a small molecule kinase inhibitor or a hormonal therapy (including investigational kinase inhibitors or hormones) within 14 days or five half-lives of the compound or active metabolites, whichever is longer, before the first dose of study treatment. Note: Subjects with prostate cancer currently receiving LHRH or GnRH agonists may be maintained on these agents.
* The subject is unable to swallow tablets
* Individuals who are known to be HIV-positive are excluded from this study. HIV positive individuals are at increased risk of lethal infection when treated with marrow-suppressive agents, and cabozantinib has not adequately been tested in this population. Also, antiretroviral therapy may have pharmacokinetic interactions with cabozantinib that have not been fully characterized yet.
* Pregnant women are excluded from this study due to the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk of adverse events in nursing infants secondary to treatment of the mother with cabozatinib, breastfeeding should be discontinued if the mother is treated with cabozantnib. These potential risks may also apply to other agents used in this study.
* Subjects may not be receiving any other study agents concurrently while on this study
