The AN-PEP, an Aspergillus niger derived endopeptidase, has been developed aiming to produce a complete luminal detoxification of gluten. If AN-PEP is able to produce a complete luminal digestion of gluten in the context of the real life of celiac disease (CeD) patients is unknown. Hypothetically, AN-PEP effect could be detected by the reduction in the excretion of GIP in stool and urine. The objective of this study is to establish the effect of the daily administration of AN-PEP compared to placebo on GIP excretion in an interventional, prospective, randomized, comparative, double-blind study in conditions mimicking the real-life of CeD treated patients. The study consists in a four-week GFD stabilization period followed by a four-week study period with patients randomized to receive active AN-PEP or placebo in a blindly manner.
Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.
|Eligible Ages||17 Years - 75 Years|
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Background: The strict gluten-free diet (GFD) is the only accepted treatment for celiac disease (CeD). However, performing a strict diet is still a non solved problem affecting the future of patients. In a real-life study it was recently shown that 89% of treated CeD patients performing a strict diet have contact with dietary gluten at least one week per 4 weeks of testing and averaging 3 weeks per month. Furthermore, 40% of patients excreted gliadin immunogenic peptides (GIP) (surrogated markers of gluten exposure) in the range for immunological activation and intestinal mucosal damage. Endopeptidases to produce a complete intraluminal proteolysis of gluten avoiding antigenic stimulation were produced to avoid damage of continuous gluten exposure. AN-PEP is an Aspergillus niger derived endopeptidase has been produced aiming to luminal detoxification of gluten have been explored for its clinical effect. However, whether AN-PEP is able to completely destroy gluten in the context of the real life of CeD patients is still unknown. Hypothesis: The investigators estimate that AN-PEP is an effective therapy for proteolysis for gluten exposure in the real-life of CeD patients and that the effect could be detected by the reduction in the excretion of GIP in stool and urine based on a clinical research model that we developed. AIMS: to establish the effect of daily administration of AN-PEP compared to placebo in terms of:
Active Comparator: Prolyl Endopeptidase
Patients blinded-receive active AN-PEP at a dose of 2 capsules/breakfast, lunch and dinner during 8 weeks (study arm)
Placebo Comparator: Placebo
Patients blinded-receive 2 capsules of a placebo (specially designed and prepared for the study) at breakfast, lunch and dinner during 8 weeks (Placebo arm).
Drug: - Prolyl Endopeptidase
Two capsules three times a day.
Other: - Placebo
Two capsules three times a day
