Erlotinib Plus Bevacizumab in Hepatocellular Carcinoma (HCC) as Second-line Therapy

The Study Drugs:

Bevacizumab is designed to block the growth of blood vessels that supply nutrients necessary
for tumor growth. This may prevent or slow down the growth of cancer cells.

Erlotinib hydrochloride is designed to block the activity of a protein found on the surface
of many tumor cells that may control tumor growth and survival. This may stop tumors from
growing. There is a commercially available form of the drug (called Tarceva) that is expected
to be very similar to the erlotinib being used for this study, but it is possible that there
may be some differences between the 2 formulations.

Study Drug Administration:

If you are found to be eligible to take part in this study, you will receive the study drugs
during 28-day "study cycles."

You will receive bevacizumab by vein on Days 1 and 15 of each cycle. The first dose of
bevacizumab will be given over about 90 minutes. If you do not have a reaction to the drug,
such as fever and/or chills, the next dose will be given over about 60 minutes. If you still
have no reaction after the second dose, each dose after that will be given over about 30
minutes. If you experience a reaction to the bevacizumab, you may be given Tylenol®
(acetaminophen) by mouth and/or an antihistamine by vein over 30 minutes before each dose to
help minimize the risk of further reactions.

You will take 1 erlotinib hydrochloride tablet by mouth every day. You should take erlotinib
hydrochloride in the morning with a full glass of water (6-8oz) at least 1 hour before or 2
hours after any food, grapefruit juice, vitamins, iron supplements, or other non-prescription
drugs.

Study Visits:

On Day 1 of Cycle 2 and beyond:

- Blood (about 3 tablespoons) will be drawn for routine blood tests and to check how well
the blood clots.

- Urine will be collected for routine testing. A 24-hour urine sample may be collected if
needed. If a 24-hour urine sample is needed, you will be provided with a special
container to collect the sample.

- You will be asked questions about any side effects you may have had and about any drugs
you may be currently taking or have taken since you last saw the study doctor.

- You will have a complete physical exam, including measurements of weight and vital
signs.

- Your performance status will be recorded.

On Day 15 of Cycle 2 and beyond, your vital signs will be recorded.

At the end of Cycle 2, 4, and every 2 cycles after that (Cycles 6, 8, 10, and so on):

°You will have CT/MRI scans of the abdomen and pelvis and chest scan (if the doctor thinks
they are needed) to check the status of the disease.

Additional tests may be done during the study if the study doctor thinks it is necessary.

Length of Treatment:

You will receive bevacizumab and erlotinib hydrochloride for as long as you are benefitting.
There is no maximum number of cycles that you can receive. If you experience severe side
effects, the treatment on this study may be delayed, stopped, or the study doctor may give
you smaller doses of the study drugs. You will be taken off study if the disease gets worse,
the side effects are too severe, or your doctor thinks that it is in your best interest to
stop receiving treatment.

End-of-Treatment Visit:

After you stop receiving all of the study drugs, you will return for an end-of-treatment
visit. At this visit, the following tests and procedures will be performed:

- Blood (about 3 tablespoons) and urine will be collected for routine tests and to learn
how well the blood clots.

- You will be asked questions about any side effects you may have had and about any drugs
you may be currently taking or have taken since you last saw the study doctor.

- You will have a complete physical exam, including measurements of weight and vital
signs.

- Your performance status will be recorded.

- CT and/or MRI scans of the abdomen and pelvis will be performed to check the status of
the disease.

Follow-Up:

After the end-of-treatment visit, the study doctor will continue to review your medical
records every 3 months until the study analysis is complete. You will also be called every 3
months for as long as the study doctor thinks is needed. During these phone calls, you will
be asked about how you are doing and if you are experiencing any health problems. The phone
call should take about 15 minutes. During the follow-up period, if the study doctor thinks it
is necessary, you may be asked to come in for a clinic visit.

This is an investigational study. Bevacizumab is FDA approved and commercially available for
the treatment of metastatic colon and rectal cancer. Erlotinib hydrochloride is FDA approved
and commercially available for the treatment of lung cancer. The use of this drug combination
in patients with advanced liver cancer is investigational.

Up to 44 patients will take part in this study. All will be enrolled at MD Anderson.

Inclusion Criteria:

1. Patients with histological or cytologically documented HCC not amenable to curative
resection (documentation of original biopsy for diagnosis is acceptable if tumor
tissue is unavailable) or clinical diagnosis by American Association for the Study of
Liver Diseases (AASLD) criteria in cirrhotic subjects is required. For subjects
without cirrhosis, histological or cytological confirmation is mandatory.

2. Patients must have measurable disease as per the modified RECIST criteria. Measurable
target lesions are defined at baseline as lesions that can be accurately measured in
at least one dimension (longest diameter to be recorded) >/= 20 mm using conventional
techniques (CT or MRI) or >/= 10 mm using spiral CT scan. Lesion must not be chosen
from a previously irradiated field, unless there has been documented disease
progression in that field after irradiation.

3. Patients who have progressed on, or were intolerant to, one prior systemic therapy
with sorafenib, completed ≥ 14 days prior to treatment day 1. Previous treatments also
allowed that do not count as systemic therapy include: surgical resection,
transarterial embolization/chemoembolization (TAE/TACE), radiofrequency ablation
(RFA), percutaneous ethanol injection (PEI), provided that the lesion(s) to be
evaluated in this study are separate from the previously treated lesions(s).

4. Eastern Cooperative Oncology Group (ECOG) performance status of
5. Childs-Pugh liver function status of A or B (only 7 points allowed).

6. Organ function: Absolute peripheral granulocyte count of >/= 1500 mm^3, platelet count
of >/= 40,000 mm^3, hemoglobin >/= 10 gm/dL. Total bilirubin albumin >/= 2.5 gm/dL; aspartate aminotransferase (AST) and alanine aminotransferase
(ALT) up to 5 X the upper limit of institutional normal (AST - 46 and ALT - 56); and
prothrombin time prolonged not more than 3 seconds greater than institutional normal,
once attempts to correct a prolonged PT have been made.

7. (Continuation of # 6) Patients who require full dose anticoagulation, who are
otherwise eligible for this trial, are allowed to have an appropriately prolonged
International Normalized Ratio (INR).

8. Negative serum pregnancy test in women with childbearing potential (those who are not
surgically sterilized or who are not amenorrheic for >/= 12 months), within one week
prior to initiation of treatment.

9. Men and women of childbearing potential must agree to use effective means of
contraception prior to study entry and for at least 180 days after the last dose of
study treatment. They must agree to use two forms of birth control, for example,
barrier methods (such as a diaphragm, cervical cap, contraceptive sponge, female
condom, or male condom), and an intrauterine device (IUD).

10. Age >/= 18 years. The agents bevacizumab and erlotinib have not been studied in
pediatric patients, thus the doses to be used in this study cannot be assumed to be
safe in children.

11. Radiographic evidence of disease progression during or following prior treatment with
sorafenib.

12. Patients must have proteinuria < 2+ or a urine protein:creatinine (UPC) ratio < 1.0.
Patients who have proteinuria >/= 2+ and UPC ratio >/= 1.0 must undergo a 24 hour
urine collection and must demonstrate
