About

The goal of this clinical research study is to learn if the combination of AvastinTM (bevacizumab) and Tarceva (erlotinib hydrochloride) can help to control advanced liver cancer. The safety of this drug combination will also be studied.

Full description

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.

Enrollment: 45 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

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 </= 2.
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 </= 2.0 gm/dL; serum 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 </= 1g of protein in 24 hours to be eligible.
