Who can take part

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 Crohn's disease who first responded to adalimumab 40 mg every two weeks and then lost that response.

Age
18 years or older
Sex
All sexes can join.
Disease stage
Crohn's disease with loss of response to adalimumab after a first response. Severe relapse (CDAI above 330) is not allowed.
Earlier treatment
Must have responded at first to adalimumab (original or similar biologic), 40 mg every two weeks, then lost response. Cannot have used vedolizumab or ustekinumab, or infliximab or ustekinumab before adalimumab.

Main reasons for not taking part

  • Pregnancy
  • Taking immunomodulators, other immunosuppressive drugs or corticosteroids
  • History of cancer, HIV, active tuberculosis or severe infections
  • Anal or perianal Crohn's disease, a stoma, or ileoanal pouchitis
  • Already on an optimized adalimumab dose, or never responded to adalimumab

About the trial

What the trial wants to find out

A substantial fraction of IBD patients with an initial response to infliximab or adalimumab later experience re-emerging active disease despite ongoing anti-Tumour Necrosis Factor (TNF) agents maintenance therapy. The optimal intervention in patients with secondary loss-of-response (LOR) is still poorly defined, as there are still scant data on how best to choose the next intervention from among dose-intensification, switch to another anti-TNF or switch out of the anti-TNF class. Moreover, according to STRIDE 2 recommendations and CALM study, optimize patients based solely on lack of biological remission (CRP, calprotectin) can be discuss. If CALM study has showed that the intervention arm based on regular monitoring fecal calprotectin, CRP and/or CDAI to optimize patients under adalimumab was significantly associated to an increase rate of mucosal healing that the standard of care strategy based on only clinical activity, TDM was not available to guide drug optimization strategy.

The 2 groups in the trial

  • Adalimumab with optimisationTreatment being tested

    Patients with Crohn's disease will be included. They will have Adalimumab with optimisation as treatment.

    Treatment: Adalimumab

  • VedolizumabTreatment being tested

    Patients with Crohn's disease will be included. They will have Vedolizumab as treatment.
