  • Onset of the above symptoms at least 6 months before the diagnostic,
  • More than one-fourth (25%) of bowel movements with Bristol stool form types 1 or 2 and less than one-fourth (25%) of bowel movements with Bristol stool form types 6 or 7 (check during the last 14 days using the stools frequency questionnaire associated to the Bristol Stools Scale "BSS"),
  • Score of abdominal pain/discomfort ≥ 2 and < 6 (using a 0 to 7 Likert point scale; daily average during the last 14 days verified at V1),
  • For non-menopausal women: with the same efficient contraception method since at least 3 months before the start of the study, and accepting to maintain this program over the study (hormonal contraception, intrauterine device or surgical intervention). For menopausal women: with or without Hormone Replacement Therapy (HRT in place since less than 3 months before the start of the study are excluded) ,

Who cannot join

  • Suffering from gastro-intestinal troubles other than IBS: lactose intolerance, Crohn disease, ulcerative colitis, celiac disease (gluten intolerance), symptomatic diverticulosis,
  • Suffering from an immunodeficiency or affected by a severe or progressive disease (cardiac, pukmonary, hepatic, renal, hematologic, infectious or neoplastic),
  • Suffering from a metabolic trouble affecting the intestinal transit function or the nutrients absorption like diabetes or unbalanced thyroid dysfunction,
  • Currently under symptomatic drug treatment acting on the intestinal sensitivity or motility (laxatives, antispasmodics, anxiolytics, antidepressants, analgesics and NSAIDs are authorized if consumed for more than 3 months with a stable dosage and maintained during the study; opioïds and narcotic analgesics are forbidden), or dietary supplementation which according to the investigator should affect study results or stopped within a too short time window before the V1 randomization visit (less than 4 weeks for oral antibiotics, pre- or probiotics, less than 2 weeks for oral antifungal and anti-diarrheal if gastroenteritis),
  • Refusing to stop the consumption of probiotics, prebiotics, or symbiotics under dietary supplement presentation or "health foods" (i.e. Lactibiane®, BION®, ultra yeast, kefir or food stuffs like ACTIMEL®, ACTIVIA® or other probiotics enriched dairy product etc.),

Questions about this trial

What is this clinical trial studying?

A study testing Saccharomyces cerevisiae CNCM I-3856 in people with Constipation-predominant Irritable Bowel Syndrome, run by Lesaffre International at 5 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 10 inclusion and 6 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 21 May 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 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. Some participants in this study may receive a placebo. 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?

Abdominal pain/discomfort score rated with Likert scale (ranging from 0 to 7) (time frame: Week 5 to Week 8). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03150212, which also lists 1 linked publication.

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 21 May 2019.
