About this study
Official title: VERDICT: In actiVE Ulcerative Colitis, a RanDomIzed Controlled Trial for Determination of the Optimal Treatment Target
Disease activity and response to therapy in ulcerative colitis (UC) can be assessed by a range of endpoints including symptoms, endoscopic mucosal activity, histological disease activity, and biomarkers. This study aims to determine the optimal treatment target, which is a research priority for the management of UC both to inform clinical practice and to help inform regulatory endpoints and targets for drug development.
Participants with active UC will be randomized in a 5:4:1 (initially 2:3:5) ratio to 1 of 3 groups, each with a different treatment target. Treatment targets will be defined as:
Read more
- Group 1: corticosteroid-free symptomatic remission
- Group 2: corticosteroid-free endoscopic + symptomatic remission
- Group 3: corticosteroid-free histological + endoscopic + symptomatic remission
An interim analysis was performed to assess the proportion of subjects that reached their assigned treatment target after 50 subjects in each group had reached the first 32-week assessment. The interim analysis and projections made based on target achievement rates for all subjects included in the interim analysis resulted in a recommendation to adjust the randomization ratio from 2:3:5 to 5:4:1 for Groups 1, 2 and 3 respectively as of May 5th, 2023. This change was necessary in order to complete the study with approximately 100 subjects achieving treatment target within each group.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Treatment Algorithm ABiological
Also called vedolizumab
Participants who are not on UC treatment at screening (or who have only used topical therapy) will require standard first-line therapy. Either oral 5-ASA and/or immunosuppressive (azathioprine, 6-mercaptopurine, or methotrexate), with optional oral corticosteroid up to a maximum of 30 mg or prednisone or equivalent, will be initiated.
Treatment Algorithm BBiological
Also called vedolizumab
Participants who are taking oral 5-ASA, immunosuppressive (azathioprine, 6-mercaptopurine, methotrexate), and/or oral corticosteroid at screening will follow the treatment algorithm.
Participants will change to intravenous vedolizumab therapy.
Participants will be assessed to determine it remission target is achieved at weeks 16, 32 and 48. If the participant has achieved their treatment target, they will continue that line of therapy. If the participant has not achieved their treatment target, treatment and/or dose escalation will be administered according to the algorithm.
Treatment Algorithm CBiological
Also called vedolizumab
Participants who are taking a TNFα antagonist (infliximab, golimumab, or adalimumab), tofacitinib, or ustekinumab therapy at screening will follow the treatment algorithm.
Participants will change to intravenous vedolizumab therapy.
Participants will be assessed to determine it remission target is achieved at weeks 16, 32 and 48. If the participant has achieved their treatment target, they will continue that line of therapy. If the participant has not achieved their treatment target, treatment and/or dose escalation will be administered according to the algorithm.

Difference in time to UC-related complication (as in the primary outcome and secondary outcomes 2 and 3)
Time to UC-related complication (as in the primary outcome and secondary outcomes 2 and 3) in the subgroup of subjects who exclusively reach their assigned target and not a higher target by Week 48.
Measured: Up to week 96
Evaluate the time to each type of UC-related complication

The Nancy Histological Index is made up of 3 items: acute inflammatory cell infiltrates, chronic inflammatory cell infiltrates, and the presence of ulceration. Histological disease activity is graded on a 5-point scale; from grade 0 (no histologically significant disease) to grade 4 (severely active disease), with this grade being determined by the scoring algorithm.

| Treatment Algorithm AAlso: vedolizumabParticipants who are not on UC treatment at screening (or who have only used topical therapy) will require standard first-line therapy. Either oral 5-ASA and/or immunosuppressive (azathioprine, 6-mercaptopurine, or methotrexate), with optional oral corticosteroid up to a maximum of 30 mg or prednisone or equivalent, will be initiated. | Biological | Symptomatic and endoscopic remission, Symptomatic remission, Symptomatic, endoscopic and histological remission |
| Treatment Algorithm BAlso: vedolizumabParticipants who are taking oral 5-ASA, immunosuppressive (azathioprine, 6-mercaptopurine, methotrexate), and/or oral corticosteroid at screening will follow the treatment algorithm. Participants will change to intravenous vedolizumab therapy. Participants will be assessed to determine it remission target is achieved at weeks 16, 32 and 48. If the participant has achieved their treatment target, they will continue that line of therapy. If the participant has not achieved their treatment target, treatment and/or dose escalation will be administered according to the algorithm. | Biological | Symptomatic and endoscopic remission, Symptomatic remission, Symptomatic, endoscopic and histological remission |
| Treatment Algorithm CAlso: vedolizumabParticipants who are taking a TNFα antagonist (infliximab, golimumab, or adalimumab), tofacitinib, or ustekinumab therapy at screening will follow the treatment algorithm. Participants will change to intravenous vedolizumab therapy. Participants will be assessed to determine it remission target is achieved at weeks 16, 32 and 48. If the participant has achieved their treatment target, they will continue that line of therapy. If the participant has not achieved their treatment target, treatment and/or dose escalation will be administered according to the algorithm. | Biological | Symptomatic and endoscopic remission, Symptomatic remission, Symptomatic, endoscopic and histological remission |

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Treatment Algorithm A, Treatment Algorithm B and Treatment Algorithm C in people with Colitis, Ulcerative, run by Alimentiv Inc. at 58 sites in 10 countries.
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 11 inclusion and 20 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 10 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 58 sites in Canada, Poland, United Kingdom, Ukraine, France and 5 more countries. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
Difference in Time to UC-related Complication Between Treatment Target Groups 1 and 3 (time frame: From date of treatment target achievement until date of first UC-related complication until end of study (Week 96), whichever came first). 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 NCT04259138, which also lists 1 linked publication.
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 10 Sep 2026.
