A Phase II Study to Evaluate the Effects of Cabozantinib in Patients With Unresectable/Metastatic Adrenocortical Carcinoma

The goal of this clinical research study is to learn if cabozantinib can help to control
unresectable (cannot be removed with surgery) or metastatic (has spread) adrenocortical
carcinomas. The safety of this drug will also be studied.

This is an investigational study. Cabozantinib is FDA approved and commercially available to
treat medullary thyroid cancer and kidney cancer. It is considered investigational to use
cabozantinib to treat adrenocortical carcinomas.

The study doctor can explain how cabozantinib is designed to work.

Up to 18 participants will be enrolled in this study. All will take part at MD Anderson.

Study Drug Administration:

If participant is are found to be eligible to take part in this study, participant will take
cabozantinib tablets by mouth 1 time each day. Participant should take participant's dose of
study drug at about the same time each day with about a cup (8 ounces) of water. Participant
should not eat for at least 2 hours before and at least 1 hour after taking participant's
dose of study drug. Participant should not crush the tablets.

If participant forgets to take participant's dose of cabozantinib and it has been less than
12 hours since the scheduled dose time, participant should take participant's dose as soon as
participant remembers. If it has been more than 12 hours, participant should not take the
drug that day, and wait for participant's next scheduled dose.

Length of Study:

Participant may continue to receive cabozantinib for as long as the study doctor thinks it is
in participant's best interest. Participant will no longer be able to take the study drug if
the disease gets worse, if intolerable side effects occur, or if participant is unable to
follow study directions.

Participation on the study will be over after the follow-up visit.

Study Visits:

On Day 1:

- Blood (about 3 tablespoons) will be drawn for pharmacokinetic (PK) testing. PK testing
measures the amount of study drug in the body at different time points.

- If participant can become pregnant, urine may be collected for a pregnancy test.

On Day 1 of Weeks 3 and 5 and then every 4 weeks after that:

- Participant will have a physical exam.

- Blood (about 3-4 teaspoons) and urine will be collected for routine tests.

- Participant will have an EKG. After Week 12, this will be performed every 8 weeks.

- If participant can become pregnant, urine or part of the above blood sample will be
collected for a pregnancy test. After Week 12, this pregnancy test will be performed
every 8 weeks.

On Day 29, blood (about 3 tablespoons), and then every 12 weeks after that, blood (about 2
teaspoons), will be drawn for PK testing.

On Day 1 of Week 9, blood (about 3 tablespoons) will be drawn for immune system testing.

Every 8 weeks:

- Participant will have an MRI, CT, or PET scan to check the status of the disease.

- If the doctor thinks it is needed, blood (about 3-4 teaspoons) will be drawn to measure
participant's hormone levels.

If at any point the disease appears to get worse, blood (about 3 tablespoons) will be drawn
for immune system testing.

Follow-Up Visit:

About 30-37 days after participant's last dose of study drug:

- Participant will have a physical exam.

- Blood (about 3-4 teaspoons) and urine will be collected for routine tests. If
participant can become pregnant, part of this urine or blood sample may be used for a
pregnancy test.

- You will have an EKG.

Inclusion Criteria:

1. The subject is >= 18 years old on the day of consent

2. Histological confirmation of ACC based on either: i). Weiss Score of >= 3 in patients
who had earlier surgical resection OR ii). biopsy results compatible with ACC in the

3. Locally advanced or metastatic disease not amenable to surgery with curative intent
with measurable disease per RECIST 1.1 (9) as determined by the investigator based on
an assessment of all known disease sites by computerized tomography (CT) scan or
magnetic resonance imaging (MRI) of chest/abdomen/pelvis within 28 days before the
first dose of cabozantinib. In patients with IV contrast allergy or borderline renal
function, CT without IV contrast or 18 FDG PET CT may be used as clinically indicated.

4. Eastern Cooperative Oncology Group (ECOG) performance status of 0-2

5. 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

Gilbert's disease, bilirubin <= 3.0 mg/dL e. Serum albumin >= 2.8 g/dl f. Serum
creatinine <= 1.5 × ULN or creatinine clearance (CrCl) >= 50 mL/min. For creatinine
clearance estimation, the Cockcroft and Gault equation should be used: Male: CrCl

result by 0.85 g. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST)

8. Capable of understanding and complying with the protocol requirements and has signed
the informed consent document

9. Sexually active patients (men and women) must agree to use medically accepted barrier
methods of contraception (e.g. male or female condom) during the course of the study

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).

amenorrhea is possibly due to prior chemotherapy, anti-estrogens, ovarian suppression
