Cholangiocarcinoma (CCA) is an aggressive cancer of the bile ducts. People with CCA have few treatment options and poor survival. Researchers want to see if a new drug can stop or slow CCA growth.


To find the safest and most effective dose of tivozanib to treat CCA and learn its overall response rate.


Adults ages 18 and older with CCA not removable with surgery and have been treated with at least one type of chemotherapy.


Participants will be screened with the following:

-Medical history

-Physical exam

-Assessment of their ability to do daily activities

-Medicine review

-Blood tests, including thyroid function tests

-Urine tests

-Electrocardiogram, to check heart function

-Pregnancy test, if needed

-Tumor biopsy, if needed

-Computed tomography scans

-Magnetic resonance imaging, if needed

Some screening tests may be repeated during the study.

Participants will be asked to enroll in protocol #13C0176. This will allow any remaining tumor or blood samples to be used in future research.

Participants will take tivozanib by mouth, once a day for 21 days per cycle or every other day per cycle. Each cycle is 28 days. They can take the drug until they have bad side effects, their CCA gets worse, or if they become pregnant. They will record their blood pressure twice daily at home. They will also keep a medication diary of each dose of tivozanib they take and any side effects.

Participants will have study visits before starting each new cycle and every 8 weeks. They will also have a follow-up visit 30 days after treatment ends at NIH, or if they are unable to come to NIH by phone, videocall, or other NIH-approved platform. Then they will be contacted 6 and 12 months later, and then once a year.

1. Patients with histologically or cytologically confirmed biliary tract cancer (BTC) (cholangiocarcinoma or gallbladder cancer). Archival tumor sample may be used but if archival tissue is not available or is not adequate, tissue biopsy will be required.

2. Patients must have disease that is not amenable to resection.

3. Patients must have had prior treatment with 1st line chemotherapy.

4. Disease must be measurable by Response Evaluation Criteria in Solid Tumors (RECIST) criteria Version 1.1.

5. Age >=18 years.

NOTE: Because no dosing or adverse event data are currently available on the use of tivozanib in subjects < 18 years of age, children are excluded from this study, but may be eligible for future pediatric trials.

6. ECOG performance status <= 2

7. Adequate organ and marrow function as defined below:

-- Hemoglobin >= 8.0 g/dL

-- Absolute neutrophil count >= 1,000/mcL

-- Platelets >= 75,000/mcL

-- Total bilirubin <= 2.5 X institutional upper limit of normal (ULN)

-- AST(SGOT)/ALT(SGPT) <= 5 X institutional ULN

-- Creatinine clearance > 30

-- Serum Albumin (g/L) > 28

8. Negative serum or urine pregnancy test at screening for women of childbearing potential (WOCBP), excepting identified false-positive pregnancy test results as permitted in the note below.

NOTE: WOCBP is defined as any female who has experienced menarche and who has not undergone successful surgical sterilization or who is not postmenopausal. WOCBP must have a negative pregnancy test (HCG blood or urine) during screening.

NOTE: Advanced biliary tract disease may secrete hormones that produce false-positive pregnancy test results. A false-positive result will be explicitly determined in this protocol at screening via a series of serial blood tests (i.e., serum HCG measurements) over a 5-day period (i.e., a minimum of a blood test on the first and fifth day of the 5-day period), in which a false-positive result not compatible with pregnancy will be defined as results indicating a consecutive, clinically low, constant level (i.e., no more than a 15% rate of increase) of HCG over the testing period. An ultrasound may be performed for clarification purposes as necessary.

9. Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and 1 month after completion of treatment.

10. Ability of subject to understand and the willingness to sign a written informed consent document.

11. Ability and willingness to co-enroll on the tissue collection protocol 13C0176, "Tumor, Normal Tissue and Specimens from Patients Undergoing Evaluation or Surgical Resection of Solid Tumors".


1. Chemotherapy, small molecule or radiation therapy within 2 weeks prior to administration of first dose of study drug.

2. Prior treatment with Tivozanib.

3. History of hepatic encephalopathy within past 12 months or requirement for medications to prevent or control encephalopathy (e.g., no lactulose, rifaximin, etc. if used for purposes of hepatic encephalopathy).

4. Inadequate recovery from any prior surgical procedure or major surgical procedure within 4 weeks prior to administration of first dose of study drug.

5. Patients with previous malignant disease other than the target malignancy within the last 3 years with the exception of basal or squamous cell carcinoma of the skin, cervical carcinoma in situ, chronic lymphocytic leukemia, or thyroid carcinoma.

6. Current active second primary malignancy, other than skin carcinoma (basal or squamous cell carcinoma), chronic lymphocytic leukemia not requiring active treatment, or differentiated thyroid carcinoma.

7. History of allergic reactions or known or suspected hypersensitivity attributed to compounds of similar chemical or biologic composition to tivozanib.

8. Patients with uncontrolled intercurrent illness including, but not limited to, ongoing or active infection requiring systemic therapy (see exceptions below), or psychiatric illness/social situations that would limit compliance with study requirements

-- Human immunodeficiency virus (HIV)-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible for this trial.

-- For patients with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable and on suppressive therapy, if indicated. For patients with HBV infection who are currently on treatment, they are eligible if they have an undetectable HBV viral load.

-- 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 treatment, they are eligible if they have an undetectable HCV viral load.

9. Significant cardiovascular disease, including: Active clinically symptomatic left ventricular failure, uncontrolled hypertension, myocardial infarction, severe angina, or unstable angina within 3 months prior to administration of first dose of study drug, history of serious ventricular arrhythmia, cardiac arrhythmias requiring anti-arrhythmic medications.

10. Uncontrolled hypertension, i.e., blood pressure (BP) of >= 150/90 mmHg; patients who have a history of hypertension controlled by medication must be on a stable dose of antihypertensive therapy such that there has been no increase in hypertensive medications or dosage (for at least 14 days) and meet all other inclusion criteria.

11. Significant hematologic, gastrointestinal, thromboembolic, vascular, bleeding, or coagulation disorders.

12. GI Bleeding (e.g., esophageal varices or ulcer bleeding) within 3 months. (Note: For patients with a history of GI bleeding for more than 12 months or assessed as high risk for esophageal variceal by the Investigator, adequate endoscopic therapy according to institutional standards is required.)

13. Complex biliary obstruction requiring bile duct stents at more than one level of the biliary tree or external biliary drainage.

14. Recurrent episodes of cholangitis (>1) in the preceding 3 months prior to enrollment.

15. Therapeutic anti-coagulation or anti-platelet therapy with the exception of low molecular weight heparin, aspirin, or factor Xa inhibitors.

16. Pregnant or lactating women. Pregnant women are excluded from this study because based on findings in animals and its mechanism of action, tivozanib can cause fetal harm when administered to a pregnant woman. In animal reproduction studies, administration of tivozanib to pregnant rats caused adverse developmental outcomes including embryo- fetal mortality. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with tivozanib, breastfeeding should be discontinued if the mother is treated with tivozanib. These potential risks may also apply to other agents used in this study.
