About this study
Official title: Responsiveness of Endoscopic Evaluation of Ulcerative Colitis Using a Central Reader Based Image Management System
The purpose of this study of this study is to assess the responsiveness and validity of CIMS (Central Image Management System)-based endoscopic evaluation of UC (Ulcerative Colitis) clinical disease activity by measuring:
The responsiveness central reader endoscopic EIs [(Endoscopic Indices) (MMCS (Modified Mayo Clinic endoscopy Subscore), UCEIS (Ulcerative Colitis Endoscopic Index of Severity) MBS (Modified Baron Score)] to clinical change from baseline to week 6 in a prospective trial of a treatment of known efficacy in UC.
Read the detailed description
This study will evaluate the responsiveness central reader based EIs for assessing clinical disease activity. Endoscopic images will be obtained from recent large multicenter randomized clinical trial and assessed using utilizing CIMS readers using EIs (MMCS, UCEIS, MBS) and a VAS (visual analog scale). The primary efficacy endpoint of this trial was clinical and endoscopic remission at week 6, with a secondary endpoint of endoscopic and clinical remission at week 10. For the same subjects, clinical data will be obtained including a modified UCDAI (Ulcerative Colitis Disease Activity Index). Central readers are blinded to clinical scores.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Endoscopic evaluation | The study population contained a broad spectrum of endoscopic disease and clinical activity. At entry to the trial patients had active disease defined by the presence of a modified UCDAI score between 4 and 10.1 Only patients who had a MMCS endoscopy subscale score according to a single central reader (n= 194 of 281 participants) were eligible for assessment in the current study. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Central Reading

The sponsor lists 3 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 2 Dec 2015. 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 Canada. 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.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Central Reading (time frame: 2 years). 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 NCT01960439, which also lists 4 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 2 Dec 2015.
