Study summary

This study aims to evaluate whether the combination of Akkermansia muciniphila with infliximab can improve intestinal mucosal healing in patients with Crohn's disease compared with infliximab alone.

Read the detailed description

This is a prospective, randomized, controlled clinical study designed to evaluate the efficacy of Akkermansia muciniphila combined with infliximab in patients with Crohn's disease.

Eligible patients will be randomly assigned to receive either intravenous infliximab at standard clinical doses combined with Akkermansia muciniphila supplementation administered once daily or intravenous infliximab alone. The primary endpoint is complete mucosal healing at Week 26, and the secondary endpoint include endoscopic remission, endoscopic response, clinical remission and clinical response at Week 26.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Adult patients aged 18 to 75 years.
  2. Documented diagnosis of Crohn's disease established at any time prior to screening by radiological, histological, or endoscopic evidence.
  3. Active Crohn's disease at screening, defined as a Crohn's Disease Activity Index (CDAI) score between 220 and 450 (inclusive).
  4. Adequate cardiac, renal and hepatic function, as assessed by the investigator based on screening laboratory tests, physical examination, and medical history, without findings that would pose an undue risk for study participation.
  5. Willingness and ability to provide written .
  6. Agreement to undergo all scheduled study procedures, including up to 3 endoscopic evaluations.

Exclusion criteria

Exclusion Criteria:

  1. Use of any biologic therapy (e.g., infliximab, adalimumab, ustekinumab, vedolizumab) within 8 weeks prior to screening.
  2. Use of systemic antibiotics or any probiotic preparation within 4 weeks prior to screening.
  3. History of any intestinal resection or other Crohn's disease-related surgery.
  4. History of or active chronic or recurrent infectious disease.
  5. History of or current .
  6. Pregnancy, lactation, or intention to become pregnant during the study period.
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

    Akkermansia muciniphila + Infliximab

    Drug: Akkermansia muciniphila + Infliximab

  • Active comparator
    Infliximab alone

    Drug: Infliximab

Interventions

  • Patients will receive infliximab alone administered intravenously at the standard dose of 5 mg/kg at Weeks 0, 2, and 6, followed by every 8 weeks thereafter.

  • DrugAkkermansia muciniphila + Infliximab

    Patients will receive oral Akkermansia muciniphila once daily starting at Week 0. Concurrently, they will receive intravenous infliximab at the standard dose of 5 mg/kg at Weeks 0, 2, and 6, followed by every 8 weeks thereafter.

What researchers measure

Primary outcomes

  1. Complete mucosal healing

    Complete mucosal healing is defined as the absence of ulceration, as determined by ileocolonoscopic examination.

    Time frame: From enrollment to the end of treatment at 26 weeks

Secondary outcomes

  1. Endoscopic remission

    Endoscopic remission is defined as a simple endoscopic score for Crohn's Disease (SES-CD) score of ≤4. The SES-CD evaluates 4 endoscopic variables-ulcer size, proportion of the surface area that is ulcerated, proportion of the surface area affected, and stenosis-in 5 segments evaluated during ileocolonoscopy (ileum, right colon, transverse colon, left colon, and rectum). The score for each endoscopic variable is the sum of values obtained for each segment. The SES-CD total is the sum of the 4 endoscopic variable scores from 0 to 56, where higher scores indicate more severe disease.

    Time frame: From enrollment to the end of treatment at 26 weeks

  2. Endoscopic response

    Endoscopic response is defined as a reduction in SES-CD from Baseline by ≥50%.

    Time frame: From enrollment to the end of treatment at 26 weeks

  3. Clinical remission

    Clinical remission is defined as Crohn's Disease Activity Index (CDAI) of ≤150 points. CDAI is a scoring system for the assessment of Crohn's Disease Activity, index values of 150 and below are associated with quiescent disease; values above that indicate active disease and values above 450 are seen with extremely severe disease.

    Time frame: From enrollment to the end of treatment at 26 weeks

  4. Clinical response

    Clinical response is defined as CDAI decrease from Baseline of ≥100 points.

    Time frame: From enrollment to the end of treatment at 26 weeks
