Effect of AN-PEP Enzyme on Gluten Digestion in Gluten Sensitive Individuals

Not Applicable

Completed

• Conditions: Non-coeliac Gluten Sensitivity
• Interventions: Dietary Supplement: Placebo; Dietary Supplement: AN-PEP

• Registration Number: NCT02060864
• Lead Sponsor: DSM Food Specialties

Brief Summary

In this trial, the effect of a low and a high dose AN-PEP will be investigated in gluten sensitive individuals. Volunteers receive a breakfast with background (0.5 g) gluten. Capsules are taken in the morning within 5 min after start of breakfast. Gastrointestinal fluid will be sampled over 3 hours to measure gluten degradation. After 5 volunteers have completed 3 test days, a blind interim analysis is performed by a third party based on which it is decided whether to proceed with the low AN-PEP dose.

Primary Outcome Measures

Name	Time	Method
Effect of 160.000 PPI AN-PEP on duodenal gluten	3-hour	Effect of AN-PEP (160.000 PPI) on gluten degradation based on amount of gluten detected in the duodenum compared with placebo over 180 min (Success is defined as at least 50% gluten degradation compared to placebo in an individual test, calculated using AUC)

Secondary Outcome Measures

Name	Time	Method
