To investigate if a daily dose of minimum 15 billion CFU of Bif195 reduces the risk of small-intestinal tissue damage in an Ibuprofen challenge model as assessed by video capsule endoscopy in a healthy US population.

This trial is a single-site, randomized, double-blind, placebo-controlled, two-armed, parallel-group trial in healthy volunteers aged 18 - 40 years. The trial will investigate the effect of daily intake of the probiotic strain Bif195 or placebo when co-administered to daily intake of 800mg of Ibuprofen.

The trial includes a run-in period of two weeks duration followed by a six weeks intervention period where Bif195/placebo and Ibuprofen 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 800mg of Ibuprofen and also be randomly assigned to 6-weeks daily intake of Bif195 or placebo product in a ratio of 1:1.
