Zileuton in Preventing Lung Cancer in Patients With Bronchial Dysplasia Clinical Trials Facts presented on Clinical Trials Search isn't designed to be a substitute for proven healthcare advice, calls or treatment using a real mD. We aren't mDs. Always confer with your physician on Zileuton in Preventing Lung Cancer in Patients With Bronchial Dysplasia conditions. Clinical Trials Search.org is a website dedicated to listing clinical research studies in human subjects. Zileuton in Preventing Lung Cancer in Patients With Bronchial Dysplasia Clinical research trials and Zileuton in Preventing Lung Cancer in Patients With Bronchial Dysplasia healthcare trials happen in a lot of of localities across the United States of America. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials generally measure the potency of new drugs. The aim of the studies / undertakings is to answer particular human medical questions. Clinical trials are a popular manner for doctors, government agencies, and private sector corporations to discover remedies for all kinds of circumstances, such as Zileuton in Preventing Lung Cancer in Patients With Bronchial Dysplasia. Zileuton in Preventing Lung Cancer in Patients With Bronchial Dysplasia Clinical Trials and other clinical trials allow volunteers to get healthcare treatment alternatives before they are available to the general public. Most times the participants receive treatment for without cost, and occasionally they are paid for their time. Sometimes there is a cost for a Zileuton in Preventing Lung Cancer in Patients With Bronchial Dysplasia clinical trial. Human subjects often receive the most effective healthcare possible for their Zileuton in Preventing Lung Cancer in Patients With Bronchial Dysplasia condition. Risks are a reality, nonetheless, and may include more or frequent dr. calls, healthcare hazards (perhaps life-threatening), and/or the treatment being ineffective. Trials are federally governed with rigorous guidelines to protect clinical trials subjects.

Zileuton in Preventing Lung Cancer in Patients With Bronchial Dysplasia
For Condition: Laryngeal Cancer,lip and oral cavity cancer,Hypopharyngeal Cancer,Oropharyngeal Cancer,Nasopharyngeal Cancer,Lung Cancer
Status: Recruiting
Sponsor(s): Barbara Ann Karmanos Cancer Institute , National Cancer Institute (NCI)
Synopsis: RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. The use of zileuton may be an effective way to prevent lung cancer in patients who have bronchialdysplasia. PURPOSE: Randomizedphase II trial to study the effectiveness of zileuton in preventing lung cancer in patients who have bronchial dysplasia.
Details: OBJECTIVES: - Determine the efficacy of zileuton, in terms of number of sites and grade of dysplastic lesions in the bronchial epithelium, in patients with documented bronchial dysplasia. - Correlate the regression of bronchial dysplasia (number and grade) and improvement in sputum cytology with the modulation of molecular biomarkers in patients treated with this drug. - Determine the overall toxicity of this drug in these patients. - Determine the 6-month stability of the chemopreventive effect of zileuton in patients who are randomized to receive initial treatment with this drug. - Determine the 6-month natural history of bronchial dysplasia in patients who are randomized to receive initial treatment with a placebo. OUTLINE: This is a randomized, double-blind, placebo-controlled, crossover, multicenter study. Patients are stratified according to clinical site, smoking status (current vs recently quit smoker), and prior cancer (none vs lung or head and neck). All patients receive oral placebo 4 times daily for 2 weeks. Patients who exhibit sufficient compliance are randomized to 1 of 2 treatment arms. - Arm I: Patients receive oral zileuton 4 times daily for 6 months followed by oral placebo 4 times daily for an additional 6 months in the absence of disease progression or unacceptable toxicity. - Arm II: Patients receive oral placebo 4 times daily for 6 months followed by oral zileuton 4 times daily for an additional 6 months in the absence of disease progression or unacceptable toxicity. Patients are followed at 4 weeks. PROJECTED ACCRUAL: A total of 134 patients (67 per treatment arm) will be accrued for this study within 1-2 years.
