What is being measured

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

  1. Detected Intraepithelial Neoplasia

    Rate of intraepithelial neoplasiae detection in the whole colon.

    Measured: During colonscopy (usually <15 min) and subsequent histological analysis

  2. Intraepithelial Neoplasia (IN) Detection Rate (True Positive Findings)

    The rate of intraepithelial neoplasiae detection in the whole colon is summarised along with the number and percentage of subjects affected. The number and percentage of false and true negative and of false and true positive findings of intraepithelial neoplasiae are also listed.

    Measured: During colonscopy (usually <15 min) and subsequent histological analysis

  3. Intraepithelial Neoplasia (IN) Detection Rate (False Positive Findings)

    The rate of intraepithelial neoplasiae detection in the whole colon is summarised along with the number and percentage of subjects affected. The number and percentage of false and true negative and of false and true positive findings of intraepithelial neoplasiae are also listed.

    Measured: During colonscopy (usually <15 min) and subsequent histological analysis

  4. Intraepithelial Neoplasia (IN) Detection Rate (True Negative Findings)

    The rate of intraepithelial neoplasiae detection in the whole colon is summarised along with the number and percentage of subjects affected. The number and percentage of false and true negative and of false and true positive findings of intraepithelial neoplasiae are also listed.

    Measured: During colonscopy (usually <15 min) and subsequent histological analysis

  5. Intraepithelial Neoplasia (IN) Detection Rate (False Negative Findings)

    The rate of intraepithelial neoplasiae detection in the whole colon is summarised along with the number and percentage of subjects affected. The number and percentage of false and true negative and of false and true positive findings of intraepithelial neoplasiae are also listed.

    Measured: During colonscopy (usually <15 min) and subsequent histological analysis

Secondary outcomes (3)
  1. The Extent and Severity of the Inflamed Mucosa

    The inflammation conditions of the mucosa were evaluated during the colonoscopy and, afterwards, in the bioptic specimens.

    Rachmilewitz EI and Saverymuttu scores were used to assess inflammation. Rachmilewitz's scoring system for endoscopic index (EI) measures granulation scattering reflected light, vascular pattern, vulnerability of mucose and mucosal damage on a scoring scale of 0 to 4 from normal to damaged.

    Saverymuttu's scoring system for enteric specimens assesses disease activity in the bowel by rating histological changes in enterocytes, crypts, lamina propria mononuclear cells and lamina propria neutrophils.

    The average score for histological changes in individual biopsy specimens was summed and converted into a grade from 1 to 4, increasing in severity.

    Measured: During colonscopy (usually <15 min) and subsequent histological analysis

  2. The Mucosal Staining Efficacy of Methylene Blue MMX® Tablets After a Total Oral Dose of 200 mg Administered During and at the End of the Intake of the Bowel Cleansing Preparation.

    The mucosal staining efficacy of Methylene Blue MMX® tablets was assessed in all 4 examined colonic regions (ascending, transverse and descending colon and rectosigmoid).

    The staining efficacy in each colon region was assessed scoring the observed staining percentage as reported below:

    1. no staining
    2. traces (poor traces in colon mucosa)
    3. detectable (at least the 25% of colon mucosa is stained)
    4. acceptable (at least the 50% of colon mucosa is stained)
    5. good (at least the 75% of colon mucosa is stained)
    6. overstained (the 100% of the colon mucosa is over stained)

    Measured: During colonscopy (usually <15 min) and subsequent histological analysis

  3. Bowel Cleansing Quality Evaluated by Boston Bowel Preparation Scale After Intake of Bowel Cleansing Formulation and of a Total Dose of 200 mg of Methylene Blue MMX Tablets Administered During and at the End of the Intake of the Bowel Cleansing Formulation

    The Boston Bowel Preparation Score (BBPS) was used to rate colon cleansing quality. Each of the following 3 regions was rated: right, mid and rectosigmoid colon. The following 4-point scale (0-3) was used.

    0 - unprepared colon segment with mucosa not seen due to solid stool that cannot be cleared

    1. - portion of mucosa of the colon segment seen, but other areas of the colon segment not well seen due to staining, residual stool and/or opaque liquid
    2. - minor amount of residual staining, small fragments of stool and/or opaque liquid, but mucosa of colon segment seen well
    3. - entire mucosa of colon segment seen well with no residual staining, small fragments of stool or opaque liquid.

    Each region of the colon received a "segment score" from 0 to 3 and these segment scores were summed for a total BBPS score ranging from 0 to 9. Therefore, the maximum BBPS score for a perfectly clean colon, without any residual liquid, is 9 and the minimum BBPS score for an unprepared colon is 0.

    Measured: During colonscopy (usually <15 min)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing oral delivery mucosal stain in people with Ulcerative Colitis, run by Cosmo Technologies Ltd at 1 site in Italy.

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 1 inclusion and 1 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 8 Feb 2019. 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 Italy. 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?

Yes. Results are posted in the registry (first posted 8 Feb 2019). 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?

Detected Intraepithelial Neoplasia (time frame: During colonscopy (usually <15 min) and subsequent histological analysis). The study lists 5 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 8 Feb 2019.
