Can probiotic spores tame Crohn's and colitis Flare-Ups?
NCT ID NCT07799428
First seen Sep 02, 2026 · Last updated Sep 03, 2026 · Updated 1 time
Summary
This trial tests whether adding Bacillus probiotic spores to standard treatment can help people with Crohn's disease or ulcerative colitis. Researchers will give 150 adults either a placebo or one of two probiotic formulas for 30 days, alongside their usual care. The goal is to see if the probiotics improve gut symptoms, reduce disease activity, and boost quality of life. The study compares changes in symptom scores and well-being over the treatment period.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Multi-strain Bacillus spore probiotics (LiveSpo COLON and LiveSpo DIA30) taken orally alongside standard IBD treatment
- What this could lead to
- If it works, adding Bacillus probiotic spores to standard IBD treatment could ease symptoms, improve quality of life, and reduce reliance on intensive therapies.
- What could go wrong
- This is an early-stage trial with a modest size, and the probiotic may not outperform placebo. Some people may experience digestive discomfort or other side effects.
