Trial design

Randomised, experimental: maat033® — 3 capsules per day, each containing approximately 460 mg microbiome product, taken once daily from d0 through d26 (27 days). control: maat030® (placebo) — 3 capsules per day from d0 through d26 (placebo capsules). auxiliary/colon preparation: moviprep (as per smpc) for colon preparation prior to dosing. Phase II trial across 1 site in France.
