Clinical Trial Summary

The aim of the present study was to determine whether oral dosing, up to 9 grams/day, of porous silica administered as a food additive can be used safely in normal weight and obese male humans, without significant side effects on gastrointestinal function, bowel emptying habits, and biomarkers.


Clinical Trial Description

This single blinded safety study will consist of two study arms and include 10 males each (18-35 years). One arm will include participants with normal weight and one with obesity. After a placebo run-in period, all subjects will be given porous silica three times daily, with increasing dose up to 9 grams/day (Phase 1). Subjects with obesity continued the study with highest dose for additional 10 weeks (Phase 2).

The participants will have weekly contacts during with the representative for the study (PI or other research staff). Clinical examinations, and blood sampling will be performed day 1, 7, 14, and 21. Faeces and morning urinary sampling day 1, and 21. Information regarding eating habits, sleep patterns, living conditions and gastrointestinal health were obtained from written forms and orally. If gastrointestinal adverse events would occur after increased dosage, the study staff will adapt the dosage protocol to facilitate adherence. ;
