Trial summary

This is a 36 week dietary intervention pilot study to evaluate the effects of lyophilized black raspberries on rectal polyp burden and biomarkers in subjects with FAP. Subjects will undergo a colonoscopy or sigmoidoscopy before study treatment to determine eligibility for the study. Read more about this study

About this study

Official title: A Pilot Study To Investigate the Biological Modulation of Familial Adenomatous Polyposis (FAP) by Lyophilized Black Raspberries

This is a 36 week dietary intervention pilot study to evaluate the effects of lyophilized black raspberries on rectal polyp burden and biomarkers in subjects with FAP. Subjects will undergo a colonoscopy or sigmoidoscopy before study treatment to determine eligibility for the study. Eligible participants will undergo a sigmoidoscopy at 36 weeks after the initiation of study treatment. The size and number of rectal polyps will be documented on a code sheet and by photograph. The efficacy outcome will include the percentage reduction in the number of rectal polyps between baseline and 36 weeks.

What is being measured

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

  1. Change From Baseline to End of Study in Number of Rectal Polyps

    Measured: Baseline and 36 weeks

  2. Change in Burden of Rectal Polyps

    The burden was measured as the sum of the number of polyps x size of polyps in mm. The change in burden was determined between baseline and 36 weeks.

    Measured: Baseline and 36 weeks

Secondary outcomes (1)
  1. Apoptosis and Cell Proliferation Measured by Percent Difference in Staining.

    A pooled analysis of all participants was used for biomarker results. Tissue from normal mucosa and rectal polyps were obtained to assay KI 67 (proliferation) and TUNEL at baseline and end of treatment. A decrease in the value of KI 67 implies lower proliferation while an increase in TUNEL is suggestive of an increase in apoptosis.

    Measured: baseline and 36 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Black raspberry (BRB) Slurry and Black Raspberry (BRB) Suppositories in people with Familial Adenomatous Polyposis, run by The Cleveland Clinic 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?

The sponsor lists 3 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 15 Feb 2016. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 15 Feb 2016). 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?

Change From Baseline to End of Study in Number of Rectal Polyps (time frame: Baseline and 36 weeks). 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?
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 15 Feb 2016.
