Reduction of Small Intestinal Ulceration Risk
Conditions
Brief summary
The primary objective of this trial is to investigate if a daily dose of minimum 50 billion CFU of Bif195 reduces the risk of small-intestinal tissue damage in an acetylsalicylic acid challenge model as assessed by video capsule endoscopy in a healthy US population aged 40 - 60 years.
Detailed description
This trial is a single-site, randomized, double-blind, placebo-controlled, three-armed, parallel-group trial in healthy volunteers aged 40 - 60 years. The trial will investigate the effect of daily intake of the probiotic strain Bif195 in two different doses or placebo when co-administered to daily intake of 300mg of Acetylsalicylic Acid (ASA). The trial includes a run-in period of two weeks duration followed by a six weeks intervention period where Bif195/placebo and ASA is co-administered. Subjects will participate in the trial for a total duration of 8 weeks including the run-in phase. Besides the screening visit, the trial will consist of 5 visits. After having given their written informed consent, subjects will complete the screening procedures to evaluate their eligibility for participation in the trial and complete a run-in period of two weeks duration to washout possible pre-trial probiotics and/or use of medication. After baseline assessments at Visit 2, subjects will start daily intake of 300mg ASA and also be randomly assigned to 6-weeks daily intake of low or high-dose active (Bif195) or placebo product in a ratio of 1:1:1.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| primary endpoint - Lewis score high dose Bif195 vs Placebo | 6 weeks | The effect of high-dose Bif195 versus placebo on small intestinal mucosal damage during a 6-week ASA challenge measured as the area-under-the-curve of the Lewis scores obtained from all video capsule endoscopies between Visit 2 (randomization) and Visit 6 (end of treatment). |
