History of Changes

Purpose

The purpose of this study is to examine whether a cocktail of two common food-grade enzyme supplements leads to decrease of serum activity markers in celiac disease patients insufficiently treated by previous gluten exclusion.

Primary Outcome Measures:

Negative seroconversion or a drop of more than 50% in anti-transglutaminase antibody blood levels by ELISA [ Time Frame: 12 weeks ]

Secondary Outcome Measures:

Negative seroconversion or drop of at least two dilution steps in the EMA test [ Time Frame: 12 weeks ]
Negative conversion for celiac antibodies in the blood by the rapid test [ Time Frame: 12 weeks ]
Change in symptoms or rash (if any) [ Time Frame: 12 weeks ]
Favorable changes in morphometry in small bowel biopsy specimens [ Time Frame: 28 weeks ]


Estimated Enrollment:	40
Study Start Date:	August 2008
Estimated Study Completion Date:	December 2015
Primary Completion Date:	December 2014 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Experimental: Enzyme treatment Enzyme for 12 weeks	Drug: STAN1 3-4 capsules/day at meals
Placebo Comparator: Placebo control Placebo enzyme for 12 weeks	Drug: Placebo enzyme 3-4 capsules/day at meals
Experimental: Enzyme + gluten Enzyme and 500 mg gluten b.i.d. for 12 weeks	Drug: STAN1+gluten 3-4 capsules/day at meals plus 500 mg gluten b.i.d

Detailed Description:

Celiac disease is genetically determined abnormal immune response to gluten, a component of wheat, rye and barley proteins that cause damage to the villous structure in the small bowel. The active disease is characterized by the induction of gluten-dependent autoantibodies to transglutaminase type-2, which are sensitive and specific non-invasive markers of gluten-sensitivity. Gluten-free diet normally leads to clearance of antibodies from serum in 6-12 months. Persistent seropositivity is a problem in patients who only incompletely exclude gluten or frequently transgress the diet. In such cases, damage of the small bowel may persist and complications may occur at higher frequency. The central hypothesis to be tested is that enzyme treatment designed to degrade a certain amount of gluten before absorption in the gastrointestinal tract will lead to a clinically meaningful decrease in auto-antibody levels in these patients.
