The Effect of a Probiotic Strain on Aspirin-induced GI Damage (PIP-L)

The Effect of Daily Intake of Two Different Doses of Bif195 on Small-intestinal Damage Induced by Acetylsalicylic Acid- a Randomized, Double-blind, Placebo-controlled, Three-armed, Parallel Group Trial in Healthy Volunteers.

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.

Study Overview

• Status: Terminated
• Conditions: Reduction of Small Intestinal Ulceration Risk
• Intervention / Treatment: Dietary supplement: Placebo; Dietary supplement: Bif195

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.
