Trial summary

Inflammatory bowel disease (IBD) groups together Crohn's Disease (CD) and ulcerative colitis (UC). Its prevalence is high representing approximately 0.4% of the population. The peak incidence for these diseases ranges between 2 and 30 years of age with a second peak for CD recently reported at 60. Read more about this study

About this study

Official title: Identification of Composite Clinical and Lab Scores Associated With a Favorable Clinical Response With Thiopurines in Patients With IBD (Inflammatory Bowel Disease): an International Clinical Trial

Inflammatory bowel disease (IBD) groups together Crohn's Disease (CD) and ulcerative colitis (UC). Its prevalence is high representing approximately 0.4% of the population. The peak incidence for these diseases ranges between 2 and 30 years of age with a second peak for CD recently reported at 60. These diseases develop over time into complications requiring in 2/3 of cases surgical resection procedures in CD and colectomy in over 20% of cases. Cohort data has recently shown that the early use of azathioprine from the first year would decrease the need for surgery. Aside from biologics, azathioprine is the most widely used immunosuppressant in IBD management. Its metabolism is highly variable in the overall population since over 10% of patients are slow metabolizers and 15% fast metabolizers. This explains partly treatment failures and side effects with thiopurines. A lot of research has shown that metabolite measurement of azathioprine (6-TGN end methylated derivatives) could be used clinically even if these results remain controversial. In fact, their positive predicative value (PPV) in clinical response does not exceed 60%. This costly testing cannot be done everywhere, is not reimbursed by national health services, and may not be used in some countries. It is, however, key in order optimize these drugs at a time when only two anti-TNFs are possible in the event of failure on thiopurines. Older studies have shown that MCV and lymphonenia could be markers for thiopurine impregnation. Recently, an American study provided a mathematic formula enabling to achieve over 80% PPV for the clinical response on AZA but this calculation needs to be confirmed and it is, moreover, patented (costly).

Read the detailed description

We suggest developing a predictive score for clinical thiopurines in IBD based on routine lab data obtained when monitoring patients on thiopurines. This initial work will enable to identify clinical and/or lab factors in order to develop a score based on an international, multicenter, cross-section study. Two hundred patients with treatment failure on thiopurines will be included and at least as many in clinical remission on thiopurines. A subsequent longitudinal study, over all recruiting centers will enable to validate the score. Finally, a prospective study will assess the clinical impact of the optimization of this score in patients sustaining a treatment failure on thiopurines. This score - if confirmed - will subsequently be at no additional cost in the management of patients on thiopurines.

What is being measured

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

  1. number of patient with therapeutic failure on thiopurines

    A therapeutic failure on thiopurines will be considered to be any patient with at least one of the following criteria:

    • For Crohn's Disease: a HBI score > 4
    • For Ulcerative Colitis: a partial Mayo score > 2 or activity reported by the expert at the time of a visit
    • For both disease:
    • Corticodependence, defined according to ECCO criteria, as an impossibility to reduce the dose of Prednisolone to less than 10 mg/day (or 3 mg/day for Budesonide) in the 3 months following corticotherapy induction.
    • Corticoresistance, defined according to ECCO criteria, as a lack of response to the dose of 0.75mg/kg of a Prednisone equivalent for 4 weeks.
    • the need to change treatment or a surgical indication.

    Measured: day 0 (inclusion)

Secondary outcomes (1)
  1. number of patient in clinical remission on thiopurines

    A clinical remission shall be considered as any patients with at least one of the following criteria:

    • For Crohn's Disease: a HBI score < 4
    • For ulcerative colitis: a partial Mayo score ≤ 2 with no subscore > 1
    • For both diseases, no corticotherapy for at least 3 months.

    Measured: day 0 (inclusion)

Questions about this trial

What is this clinical trial studying?

An observational study of Inflammatory Bowel Diseases, run by Centre Hospitalier Universitaire de Saint Etienne at 15 sites in France.

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 5 inclusion and 13 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 22 Aug 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 15 sites in France. 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?

number of patient with therapeutic failure on thiopurines (time frame: day 0 (inclusion)). 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 22 Aug 2017; AzTrials last refreshed its copy on 8 Nov 2026.
