sorafenib and thoracic radiation for patients with non-small cell lung cancer

Conditions: Lung Cancer

Summary: the goal of this clinical research study is to find the highest safe dose of sorafenib that can be given in combination with radiation therapy to people with lung cancer. the ability of both the study drug and radiation to control the disease will also be studied.

the study drug: sorafenib is designed to block the function of important proteins in cancer cells. these proteins, when active, are in part responsible for the growth and behavior of cancer cells. study drug dose escalation: if you are found to be eligible to take part in this study, you will be assigned to a study group based on when you joined this study. up to 4 groups of 3-6 participants will be enrolled in the phase i portion of the study. enrolled in the phase i portion, the dose of sorafenib you receive will depend on when you joined this study. the first group of participants will receive the lowest dose level of sorafenib. each new group will receive a higher dose of sorafenib than the group before it, if no intolerable side effects were seen. this will continue until the highest tolerable dose of sorafenib is found. all participants will receive the same type and amount of radiation. study drug administration: you will take sorafenib capsules 1-2 times every day beginning on day 1 of radiation therapy. if you are in the first group on study, you will take the study drug 1 time. if you are in any other groups, you will take the study drug 2 times a day. you will take the study drug without food (1 hour before or 2 hours after eating). radiation therapy: before receiving radiation therapy, you will have a "marking session". at this visit, you will have a computed tomography (ct) scan that will be used to help to plan out the radiation therapy. this will take about 45 minutes. before receiving radiation, you will also have a single photon computed tomography (spect) scan of your lungs. you will be given 15 radiation treatments, once a day, 5 days a week, monday-friday. each treatment will take about 30 minutes. you will sign a separate consent form for radiation therapy and the procedure will be described to you in more detail. clinical visits: you will have routine clinical visits every week while receiving radiation therapy. the information collected during these clinical visit will be used for the study. at these visits, the following tests and procedures will be performed: * you will have a physical exam, including measurement of your blood pressure and weight. * you will be asked about any side effects you may be experiencing and any new drugs you may be taking. * you will be asked how well you are able to perform the normal activities of daily living (performance status evaluation) * blood (about 3-4 teaspoons) will be drawn for routine tests. * you will have any tests that doctor feels medically necessary urine will be collected every week while you are taking sorafenib and receiving radiation therapy for routine tests. length of study: you will remain on study for 6 weeks after you complete radiation therapy. you will be taken off the study early if the disease gets worse or intolerable side effects occur. end-of-study visit: you will have an end-of-study visit 4-6 weeks after you stop receiving radiation. at this visit, you will have a ct scan to check the status of the disease. follow-up visits: your first follow-up visit will be at 6 weeks (+/- 7 days) after radiation therapy and the second follow-up appointment will be at 10 weeks (+/- 7 days) after radiation therapy. you will then have follow up visits every 3 months. at these visits, you will go though the following: * your complete medical history will be recorded. * you will have a physical exam, including measurement of your weight and blood pressure. * you will be asked how well you are able to perform the normal activities of daily living (performance status evaluation). * you will be asked about any drugs you may be taking. * blood (about 3-4 teaspoons) and urine will be collected for routine tests. * you will also have chest x-ray. * you will have a computed tomography (ct) scan of your chest area. * the location, type, and size of all measurable lesions will be recorded. * if your doctor thinks it is necessary, you will have a positron emission tomography(pet)/ct scan. * if your doctor thinks it is necessary, you will have an electrocardiogram (ecg -- a test that measures the electrical activity of the heart). * you may have a lung perfusion scan to see if all regions of your lung are equally functional or not. this is called lung spect scan. * you will have a lung functional test (pft) if your doctor thinks it is necessary. all these tests are routine examinations as you would have without participating in this study in order to know the status of the disease. this is an investigational study. sorafenib is fda approved and commercially available for renal cell carcinoma. the radiation therapy schedule used for this study is standard treatment for lung cancer patients. the use of sorafenib with radiation therapy is investigational. up to 64 patients will take part in this study. all will be enrolled at m. d. anderson.
