About this study

Official title: R01 CA90759: The Effects of Lycopene on High Risk Prostatic Tissue

The purpose of this research study is to compare the effects of a lycopene supplement made from tomatoes to a placebo (a capsule with no active ingredients) in men who have abnormal cells in the prostate, but have not yet had cancer detected. This study will allow us to see if taking lycopene for six months leads to favorable changes in abnormal prostate tissue and in chemicals measured in the blood that go along with a higher risk of developing cancer.

Being tested

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Tissue Biomarkers

    We will use conventional immunohistochemistry and computer-based image analysis to test the hypothesis that the lycopene supplements alter the expression of proteins marking the status of proliferation, differentiation, cell regulation and apoptosis in high-risk tissue.

    Measured: baseline and 6 months

  2. Changes in Serum Biomarkers

    Change in serum lycopene, umol/L

    Measured: baseline and 6 months

Secondary outcomes (1)
  1. Changes in Nuclear Morphometry

    We will use a computerized image analysis system designed for the chemoprevention setting to test the hypothesis that the antioxidants cause a favorable change in a nuclear morphometry index based on nuclear size, shape and chromatin texture.

    Measured: baseline and 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Lycopene 30mg in people with Intraepithelial Prostatic Neoplasia and Prostatic Neoplasms, run by University of Illinois Chicago at 2 sites 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?

The sponsor lists 10 inclusion and 3 exclusion criteria. 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: finished, as of the sponsor's last update on 19 Nov 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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. Some participants in this study may receive a placebo. 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?

Yes. Results are posted in the registry (first posted 4 Jun 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Tissue Biomarkers (time frame: baseline and 6 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01443026, 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 19 Nov 2019.
