About this study
Official title: A Randomized Study of the Effect of Alpha-tocopherol (AT) on 13-cis-retinoic Acid (13-cRA) Toxicity in a Preliminary Chemoprevention Trial in Former and Current Smokers
RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. The use of isotretinoin may be an effective way to prevent lung cancer. Vitamin E may prevent the side effects of isotretinoin therapy.
PURPOSE: Randomized clinical trial to study the effectiveness of vitamin E in preventing the side effects of isotretinoin in former and current smokers who are receiving isotretinoin to prevent lung cancer.
Read the detailed description
OBJECTIVES: I. Determine whether the addition of alpha-tocopherol (AT; vitamin E) to isotretinoin decreases the incidence of Grade II and higher toxicity of isotretinoin when administered to former and current smokers. II. Determine the compliance rate of isotretinoin of smoker and former smokers with or without AT over a six month period. III. Determine the feasibility of recruiting former and current smokers with or without AT over a six month period. IV. Determine the effect of isotretinoin administration on serum retinol and retinol-binding protein levels in these patients.
OUTLINE: This is randomized, placebo controlled study. Patients are stratified by smoking status (current smoker vs former smoker) and age (less than 50 vs 50 and over). Patients are randomized to be take alpha-tocopherol (AT) orally and isotretinoin orally daily (arm I) or isotretinoin orally plus AT placebo orally daily (arm II). Treatment in each arm continues for 6 months. Patients are followed at 1, 3, 6, and 7 months from start of treatment.
PROJECTED ACCRUAL: There will be 300 patients (150 per arm) accrued into this study over an estimated 9 months.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Vitamin E (AT) and Isotretinoin in people with Lung Cancer, run by M.D. Anderson Cancer Center.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: withdrawn, as of the sponsor's last update on 22 Feb 2012. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was withdrawn before enrolling participants, so there are no results.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Effect of Alpha-tocopherol (AT) on 13-cis-retinoic Acid (13-cRA) Toxicity (time frame: 6 Months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Feb 2012; AzTrials last refreshed its copy on 8 Nov 2026.
