Clinical Trial Summary

The aim of the study is to confirm/prove safety of the probiotic and production of serpin in humans.


Description:

This trial is a multicenter, double blind, randomized, placebo controlled, 2 by 2 cross-over design (i.e. 2-sequences, 2-periods, 2-treatments) for each specific population (i.e. self-reported Non Coeliac Gluten Sensitivity and Coeliac Disease subjects). 1 capsule of BL NCC 2705 or placebo will be given twice a day in the morning and in the evening with a meal over 2 periods of 4 days. On day four a single dose of gluten (3g) will be administered and duodenal fluid will be collected in the following hours through a naso-intestinal catheter. The viability of BL NCC 2705, the production of serpin and its effects on gluten digestion and intestinal enzymatic activity will be determined. No chronic administration of gluten as a challenge is foreseen in the study. After a wash out period of minimum 2 weeks, period will be repeated.

Outcome

Type Measure Description Time frame Safety issue
Primary incidence, type and severity of adverse event incidence, type and severity of adverse event from Baseline to end of study (up to maximum 43 days)
Primary Gastro-intestinal tolerability: visual analog scale Sum of visual analog scale for gastro-intestinal symptoms assessment (nausea, vomiting, diarrhea, audible bowel sound, flatulence and abdominal cramping symptoms are assessed). Each scale is from 0 (no symptom) to 100mm (maximum symptom). The maximum sum value is 600. from Baseline to end of study (up to maximum 43 days)
Secondary Concentration of bacterial Serpin RNA and/or proteins (ng/mL) in duodenal aspirates Measurements via RT-PRC and immuno-assay 19 sampling over 6h50 hours at visit 2 (day 4) and visit 3 (from day 22 to day 36)
Secondary Concentration of Probiotic BL NCC 2705 (ng/mL) in duodenal aspirates Measurements via PCR 19 sampling over 6h50 hours at visit 2 (day 4) and visit 3 (from day 22 to day 36)
Secondary Concentration of gluten derived pepides in duodenal aspirates Effect of BL NCC 2705 on gluten digestion based on the amount of gluten peptides detected in duodenal apsirates 10 sampling over 3h30 at visit 2 (day 4) and visit 3 (from day 22 to day 36)
Secondary Concentration of gluten derived pepides in urine Effect of BL NCC 2705 on gluten digestion based on the amount of gluten peptides detected in urine 10 sampling over 3h30 at visit 2 (day 4) and visit 3 (from day 22 to day 36)
Secondary Level of elastase (Units/ mL) activity in duodenal aspirates Measurements of proteolytic activity based assay 19 sampling over 6h50 hours at visit 2 (day 4) and visit 3 (from day 22 to day 36)
