Inositol in Preventing Lung Cancer in Patients With Bronchial Epithelial Dysplasia Who Are Current or Former Smokers Clinical Trials Data presented on Clinical Trials Search is not meant to be a substitute for qualified medical advice, visits or professional assistance with a genuine dr.. We are not doctors. Always consult your mD about Inositol in Preventing Lung Cancer in Patients With Bronchial Epithelial Dysplasia Who Are Current or Former Smokers conditions. Clinical Trials Search.org is a site devoted to listing clinical research studies in human subjects. Inositol in Preventing Lung Cancer in Patients With Bronchial Epithelial Dysplasia Who Are Current or Former Smokers Clinical research trials and Inositol in Preventing Lung Cancer in Patients With Bronchial Epithelial Dysplasia Who Are Current or Former Smokers medical trials take place in many of places throughout the U.S.A.. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials usually evaluate the effectiveness of new does drugs. The purpose of the studies / projects is to solve specific human healthcare questions. Clinical trials are a popular way for mDs, government agencies, and private sector companies to find cures for all varieties of conditions, like Inositol in Preventing Lung Cancer in Patients With Bronchial Epithelial Dysplasia Who Are Current or Former Smokers. Inositol in Preventing Lung Cancer in Patients With Bronchial Epithelial Dysplasia Who Are Current or Former Smokers Clinical Trials and other clinical trials allow for volunteers to have health treatment options before they are available to the masses. Many times the human subjects acquire professional assistance for free of charge, and sometimes they are compensated for their time. Occasionally there is a cost for a Inositol in Preventing Lung Cancer in Patients With Bronchial Epithelial Dysplasia Who Are Current or Former Smokers clinical trial. Test subjects typically obtain the finest healthcare available for their Inositol in Preventing Lung Cancer in Patients With Bronchial Epithelial Dysplasia Who Are Current or Former Smokers condition. Dangers are a reality, nevertheless, and might include additional or frequent doctor trips, medical dangers (possibly life-jeopardising), and/or the treatment being ineffectual. Trials are federally regulated with strict guidelines to protect clinical trials patients.

Inositol in Preventing Lung Cancer in Patients With Bronchial Epithelial Dysplasia Who Are Current or Former Smokers



Inositol in Preventing Lung Cancer in Patients With Bronchial Epithelial Dysplasia Who Are Current or Former Smokers

For Condition: Non-small cell lung cancer,Small Cell Lung Cancer
Status: Recruiting
Sponsor(s): British Columbia Cancer Agency , National Cancer Institute (NCI)
Synopsis: RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. Inositol may be effective in preventing the development of lung cancer in patients with bronchialepithelialdysplasia. PURPOSE: Phase I trial to study the effectiveness of inositol in preventing lung cancer in current or former smokers who have bronchial epithelial dysplasia.
Details: OBJECTIVES: - Determine the safety of inositol for the prevention of lung cancer in patients with bronchial epithelial dysplasia who are current or former smokers. - Determine the potential efficacy of this drug in regression of existing dysplastic lesions or prevention of appearance of new dysplastic lesions in these patients. - Determine whether intake of this drug can facilitate smoking cessation in patients who are current smokers. OUTLINE: This is a dose-escalation study. Patients receive oral inositol twice daily. Treatment continues for 1 or 3 months in the absence of disease progression or unacceptable toxicity. Cohorts of 4-12 patients receive escalating doses of inositol until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 4 of 12 patients experience dose-limiting toxicity. Once the MTD is determined, 10 patients are treated with inositol twice daily at the MTD for 3 months in the absence of disease progression or unacceptable toxicity. Patients are followed at 1 month. PROJECTED ACCRUAL: A total of 4-28 patients will be accrued for this study.
