AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults with active, symptomatic Crohn's disease who need a biologic treatment and show signs of inflammation on stool tests and MRI.

Age
18 years or older
Sex
All sexes can join.
Disease stage
Active Crohn's disease with symptoms (CDAI above 150) and signs of inflammation: fecal calprotectin above 250 and MRI signs of activity.
Earlier treatment
Needs treatment with a biotherapy, according to the investigator.
Biomarker or test result
Fecal calprotectin above 250 together with MRI signs of inflammatory activity.

Main reasons for not taking part

  • Severe obstructive symptoms
  • Uncontrolled abscess inside the abdomen
  • Isolated lesions around the anus only
  • Ostomy (temporary or permanent) or total colectomy
  • Pregnant or breastfeeding women

About the trial

What the trial wants to find out

Crohn's disease (CD) is a chronic inflammatory bowel disease (IBD) that can dramatically affect the quality of life of patients. Due to its transmural nature (involvement of the entire thickness of the intestinal wall), it naturally progresses to intestinal destruction (stenosis, fistula) which requires intestinal resection in approximately half of patients during their follow-up. The long-term goal for patients is to maintain a normal life, that is, without symptoms and without intestinal destruction. For this, the short and medium term therapeutic objectives have evolved in recent years. Clinical remission is not a sufficient goal since it has failed to alter the natural history of the disease. The current objective to be achieved is the combination of clinical remission and endoscopic mucosal healing since it is associated with a reduced risk of progression (reappearance of symptoms, hospitalization, intestinal resection). Fecal calprotectin, better accepted than colonoscopy, is a non-invasive biomarker of endoscopic inflammatory activity in CD. The CALM study recently showed that close follow-up with clinical and biological evaluation (assays of CRP and fecal calprotectin), called "tight control", associated with therapeutic intensification in the absence of clinical or biological remission, was associated with a better rate of endoscopic mucosal healing at 1 year than follow-up based solely on symptoms. Thus, the "CALM" strategy is considered to be the current benchmark.

Transmural healing evaluated by MRI is also a promising objective associated with a reduced risk of progression (reappearance of symptoms, hospitalization, bowel resection). In addition, it could prevent intestinal destruction. A recent study by our team suggested that calprotectin (mucosal assessment) and MRI (transmural assessment) may be complementary and be a better therapeutic goal. We hypothesize that a "CALM + MRI" strategy concomitantly targeting transmural healing would be superior to the "CALM" strategy alone in maintaining clinical remission without corticosteroids in patients with CD treated with biotherapies.

The 2 groups in the trial

  • CALMNo study treatment, for comparison

    Tight control of inflammatory activity by calprotectin.

  • CALM + IRMOther group

    Tight control of inflammatory activity by calprotectin associated with transmural evaluation.

    Treatment: MRI
