Brief Summary:
The goal of this clinical research study is to learn if erlotinib hydrochloride (Tarcevaâ (OSI-774 ) can prevent cancer in the mouth of people with a high risk of developing cancer in the mouth. The safety of this drug will also be studied, as well as the drug's effect on different cells in the body.

Condition or disease Intervention/treatment Phase
Oral Cancer Drug: Erlotinib Drug: Placebo Phase 3

  Hide Detailed Description

Detailed Description:

Erlotinib hydrochloride is designed to block the activity of an enzyme found on the surface of many tumor cells that may control tumor growth and survival. This may keep tumors from growing.

If you are found to be eligible to participate in the study, you will be randomly assigned (as in the toss of a coin) to receive either erlotinib hydrochloride or placebo. A placebo is a substance that looks like the study drug but has no active ingredients. Neither you nor the investigators will know which treatment group you have been assigned to. However, in the event of a medical emergency, the study chair can find out which group you are in, if necessary. You can be informed which of the groups you were assigned to, after the study has ended. There is no certainty that you will have an effect from the treatment, or if you will be placed in a group with the active study drug.

While on study, you will take the study dose (either erlotinib hydrochloride or placebo) by mouth, in tablet form, once a day. Tablets should be taken in the morning 1 hour before or 2 hours after a meal, other medications, vitamins, and iron supplements, with no more than 7 ounces of water. You should take the study dose around the same time every day. Every attempt should be made to keep from vomiting the dose, for at least 30 minutes after taking it. For example, if you feel nauseated before or after taking the study dose, anti-nausea medications should be used. If you vomit after taking the study dose, the dose can be taken again only if the tablet(s) can actually be seen and counted (in other words, they have not dissolved yet). You will need to note the time you take each dose of medication throughout the study on a calendar that the study nurse will give to you.

At Months 1, 3, 6, 9, and 12, you will return to clinic. You will have a physical exam including measurement of vital signs. You will have a careful examination of the inside of your mouth.You will have blood (about 2 teaspoons) drawn for routine tests and to check your liver function (about 1-2 teaspoons). At Months 3, 6, and 12, you will have blood (about 2 teaspoons) drawn for research testing and to measure the level of study drug in the body.

Your study doctor will ask you about any medications you are taking, how you are feeling (symptoms), and your current smoking and alcohol usage.

The nurse or study coordinator will collect the medication you did not take, as well as your completed pill diaries, at every clinic visit. At Months 1, 3, 6, and 9, you will also be given new study medication and pill diaries.

You may also have another small biopsy performed from the inside of your mouth in the area where the cells that might become cancerous are located. The biopsy will be performed by your doctor and will be sent to a lab for testing. At months 3 and 12, the doctor will also count and measure any red or white patches on the inside of your mouth. Biopsies will be taken after 3 months of treatment and at the end of 12 months of treatment. The tissue will be tested to see if there are any cells that might become cancerous.

Following the end of treatment, you will return to the clinic every 6 months for 2 years. You will have a complete physical exam, including measurement of vital signs. You will have a careful examination of the inside of your mouth. You will have blood drawn (about 2 teaspoons) for routine tests, to check your liver function, and for research testing. Your study doctor will ask you about any medications you are taking and how you are feeling (symptoms), and your current tobacco and alcohol use.

In addition, at the final clinic visit, you will also take part in a personal interview. During the interview, you will be asked questions regarding socio-demographic information (such as age and race), nutrition habits, current and earlier tobacco use, alcohol use habits, family history of cancer, use of medications, and how you are feeling. The interview will take about 90 minutes to complete. The purpose of the interview is to collect information to learn if there is a relationship between certain factors and your risk of developing cancer of the mouth. You may be contacted in the future in order to collect more information.

You may be taken off study if you are not able to follow the doctors' instructions, serious side effects occur, or the doctor thinks it is in your best interest to leave the study. If you are taken off study for any reason, you will be asked to return to the clinic for a final clinic visit, preferably within 14 days after leaving the study.

This is an investigational study. Erlotinib hydrochloride is approved by the FDA for treatment of NSCLC. Its use in this study is considered investigational. Approximately 491 patients will be screened for this study. Up to 120 will be enrolled at MD Anderson.

Male or female patients with one of the following: (a) loss of heterozygosity (LOH) at 3p14 and/or 9p21 in the oral IEN of patients with a history of curatively treated oral cancer or (b) LOH at 3p14 and/or 9p21 plus at one other chromosomal region in the IEN of patients with no oral cancer history.
  2. Participants must have confirmed diagnosis of oral IEN lesion with LOH. (Note:The initial screening biopsy of oral IEN lesion with LOH must be obtained within 12 months of study enrollment.
