About this study
Official title: Carotenoid-Rich Diet Trial to Reverse CIN II
RATIONALE: A diet rich in carotenoids may be an effective treatment for cervical dysplasia.
PURPOSE: Randomized phase II trial to study the effectiveness of a carotenoid rich diet in treating patients with cervical dysplasia.
Read the detailed description
OBJECTIVES: I. Determine whether a carotenoid rich diet will cause a significant increase in the regression of disease in patients with grade I or II cervical intraepithelial dysplasia. II. Determine whether the regression of disease in this patient population is reflected in the modulation of intermediate biological markers (viral genome copy number of human papilloma virus (HPV) and HPV E6/E7 expression).
OUTLINE: This is a randomized, controlled study. Patients are randomized to one of two treatment arms. Arm I: Patients receive dietary counseling and eat 5-10 servings of carotenoid rich fruit and vegetables each day for a year. Arm II: Patients receive no counseling and maintain their normal diet. Carotenoid levels, HPV status, progression of cervical dysplasia, and diet (by food frequency checklist and food diary) are monitored in both groups.
PROJECTED ACCRUAL: A total of 240 patients will be accrued for this study within 5 years.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing preventative dietary intervention in people with Cervical Cancer, run by University of California, San Diego at 1 site in United States.
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The record says: withdrawn, as of the sponsor's last update on 20 May 2014. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00003094, which also lists 7 linked publications.
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 20 May 2014.
