Outcome Measures

Primary Outcomes (5)

  • Incidence of adverse events

    The number of solicited and unsolicited adverse events will be recorded.

    Up to 6 months

  • Severity of adverse events

    The severity will be graded according to the definitions and values stated in CTCAE V04 v4.

    Up to 6 months

  • Effect on Harvey Bradshaw Index (HBI)

    The effect on Crohn's disease activity will be evaluated using the HBI.

    Up to 6 months

  • Effect on inflammation, as indicated by C-reactive protein (CRP)

    The changes in CRP from baseline will be evaluated.

    Up to 6 months

  • Effect on inflammation, as indicated by fecal calprotectin

    The changes in fecal calprotectin levels from baseline will be evaluated.

    Up to 6 months

Secondary Outcomes (1)

  • Effect on the incidence and levels of AIEC

    Up to 6 months

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male or female ≥ 18 years of age
  • Inactive Crohn's disease in clinical and objective remission with a Harvey-Bradshaw Index (HBI) \< 4
  • Permitted CD medications expected to remain stable during the period of the study (see Section 7 "Concomitant Crohn's Disease Medications" for allowed and prohibited drugs).
  • Crohn's disease history ≥ 6-month duration
  • CRP (C-reactive protein) within normal range at the Screening visit (based on normal range of the local laboratory)
  • Fecal calprotectin level ≤ 150 µg/g at the Screening visit
  • AIEC detected in the stool
  • Females of childbearing age must be using an effective method of contraception to prevent pregnancy and agree to continue to practice an acceptable method of contraception for the duration of participation in the study (contraceptive measures considered adequate are: intrauterine devices, hormonal contraceptives, such as contraceptive pills, implants, transdermal patches, hormonal vaginal devices or injections with prolonged release).
  • Negative pregnancy test for women of childbearing age (menarche to menopause)
  • Patient understands the study procedures, and can sign the informed consent, and the authorization to release relevant protected health information to the Study Investigator.

You may not qualify if:

  • Active Crohn's disease with a Harvey-Bradshaw Index (HBI) ≥ 4
  • Ongoing gastrointestinal pathology: colorectal tumor, gastrointestinal bleeding
  • Active malignancies or any malignant disease within the past 5 years
  • Indeterminate colitis, ulcerative colitis
  • Colectomy or partial colectomy (less than ileo-transverse colonic anastomosis).
  • Colonic or small bowel stoma
  • Active perianal lesions
  • Women who are pregnant or nursing, or plan to become pregnant during the study period
  • Severe uncontrolled diseases that could increase the risk for subjects participating in the study, including but not limited to: heart diseases, congestive heart failure, hypertension, lung diseases; endocrine diseases; clinically significant renal disease characterized by a glomerular filtration rate \< 60mL/min, hepatic diseases, haematological disorders, or other conditions that in the opinion of the Investigator could interfere with the interpretation of the study results.
  • Taking supplemental probiotics in the form of pills or tablets.
  • History or planned procedures specifically aimed at modifying the gastrointestinal microbiota within the past year.
  • Topical gastrointestinal treatment (e.g., enemas) in the 2 weeks prior to the Screening visit or planned during the study period
  • Use of bowel cleansing or preparation for endoscopy, TDM or MRI in the 4 weeks prior to the Screening visit or planned during the study period.
  • Receipt of antibiotics 4 weeks before the Screening visit or planned during the study period.
  • Known allergy or hypersensitivity to an excipient in the study drug or placebo
  • +6 more criteria
