Clinical Trial Summary

The main purpose of this study is to assess the concentration of elemental impurities in blood and urine after chronic administration of Smecta® in subjects with chronic functional diarrhoea. For exploratory purposes, the potential effects of diosmectite on bowel microbiote composition will be investigated.

Outcome

Type Measure Description Time frame Safety issue
Primary Mean Change From Baseline in Blood Lead Levels During the Treatment Period and Post-treatment Follow-up Period Baseline blood lead levels (BLL) were defined as the average between the available screening and pre-dose (Day-1) values. Values below the limit of detection (LOD) or below the lower limit of quantification (LLOQ) were replaced by LOD/2 or LLOQ/2 values.
The absolute mean change from baseline in BLL during the treatment period is presented for the timepoints: 2 hours after the first dose, and prior to and after the second and third doses on Days 1 and 35, prior to the first dose on Days 2, 8, 15, 22 and 29, and on Day 36 in the morning.
The absolute mean change from baseline in BLL during the post-treatment follow-up period is presented for the timepoints: Day 65, Day 95, and Day 125 (End of Study).
Screening and pre-dose Day -1 up to Day 125.
