Erlotinib Prevention of Oral Cancer (EPOC)

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.

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

      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

      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.
