About this study
Official title: Randomized Window of Opportunity Trial of Anthocyanin Extract and Phospholipid Curcumin in Subjects With Colorectal Adenoma
It has been shown that curcumin and cyanidin-3-glucoside (C3G) have anticancer effects. In this clinical trial we compare the affect of their combination vs placebo in a four weeks intervention before endoscopic polypectomy.
Read the detailed description
Colonic adenomatous polyps are pre cancer lesions and are used as intermediate markers for testing agents with potential cancer prevention.
Meriva© is a bioavailable form of curcumin, a polyphenolic compound obtained from turmeric (Curcuma longa L.) endowed with anti-inflammatory, antioxidant and antitumor effects. In vivo data indicate that curcumin formulated with phosphatidylcholine furnishes higher blood levels of parent agent than natural curcumin.
Mirtoselect©, an anthocyanin mixture from bilberry containing isolated cyanidin-3-glucoside (C3G), the most abundant anthocyanin in diet, prevents intestinal adenoma formation in the Apc(Min) mouse model.
The investigators hypothesize that the combination of both agents will decrease the expression of proteins involved in colon tumorigenesis relative to placebo.
The change of biomarker expression between pre-treatment biopsy and post-treatment endoscopic resection in the target adenoma and the normal rectal mucosa will be the response measures.
The primary response measure is the change of immunohistochemical (IHC) expression of β-catenin in adenomatous tissue and normal rectal mucosa. Secondary response measures are the changes of IHC Nuclear Factor-Kβ (NFKβ), cell proliferation by Ki-67 Labeling Index and apoptosis by P53 in adenomatous and adjacent normal mucosa.
The study design is a phase II, randomized, double blind, placebo controlled, window of opportunity trial of the combination of Mirtoselect 1 gr/day+Meriva 1 gr/day or placebo. Subjects with histological confirmation of colorectal adenomatous polyps >1 cm not suitable to immediate complete removal will be enrolled in a 4-week intervention trial before endoscopic polypectomy.
The demonstration of a biological activity of the two agent combination may provide the rationale for a phase III trial aimed at reducing the risk of colon cancer in high risk subjects.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
It has been shown that curcumin and cyanidin-3-glucoside (C3G) have anticancer effects. In this clinical trial we compare the affect of their combination vs placebo in a four weeks intervention before endoscopic polypectomy.

The demonstration of a biological activity of the two agent combination may provide the rationale for a phase III trial aimed at reducing the risk of colon cancer in high risk subjects.

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 in Beta Catenin Expression (time frame: baseline and 4 weeks). 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 21 Nov 2024; AzTrials last refreshed its copy on 7 Nov 2026.
