Clinical Trial Summary

The purpose of this study is to investigate if the probiotic Bifidobacterium breve Bif195 (Bif195) will result in improvement in clinical outcome in patients with diarrhea-predominant irritable bowel syndrome (IBS).

Description:

IBS is the most frequently diagnosed gastrointestinal disease and also the most common cause of referrals to gastroenterology departments in Denmark.

The possibilities for treatment for IBS are limited. Treatment strategies that involve the microbiota provide symptom relief in some IBS patients. Several studies have demonstrated that the composition of the gut microbiota in IBS patients is different from healthy controls.

Probiotic interventions has shown promising results, but it currently remains unknown which probiotics are effective and which are not.

A new probiotic bacterium, Bifidobacterium breve Bif195 (Bif195) has been identified and has shown great effects on preventing enteropathy and ulcers on the gut mucosa in healthy volunteers given acetylsalicylic acid, and thereby Bif195 has also shown a potential in reducing gut permeability defects. This bacterium has not yet been investigated in IBS patients.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in IBS symptoms from baseline measured by IBS-severity scoring system (IBS-SSS) at 8 weeks	IBS-SSS is a composite score of abdominal pain, number of days with abdominal pain, bloating/distension, satisfaction with bowel habits, and IBS-related quality of life. Each measure is rated from 0 to 100, with total scores ranging from 0 (best) to 500 (worst).	8 weeks
Secondary	Change in quality of life from baseline measured by Irritable Bowel Syndrome-Quality of Life (IBS-QOL) Questionnaire Scores at 8 weeks	The IBS-QoL questionnaire consists of 34 items, each with a 5-point response scale. The 34 items are based on the following eight variables: health worries, food avoidance, body image, dysphoria, interference with activity, social reactions, sexual activity and relationships. The IBS-QoL score will be transformed into a 0-100 scale using the formula: total score = (sum of the items-34/170) ×100. Low score (best)	8 weeks
Secondary	Changes from baseline in bowel habits at 8 weeks	measured by frequency/day and Bristol Stool Form Scale. The Bristol Stool Form Scale is divided into seven categories were a low value indicate constipation and a high value indicate diarrhoea.	8 weeks
Secondary	Change from baseline in abdominal pain at 8 weeks	Measured by a VAS scale from 0-10. 0 = no pain, 10 = worst pain	8 weeks
Secondary	Adverse events	Reported according to IHC-GCP	16 weeks
