All methods will be used from at least 2 weeks (4 weeks in the case of hormonal contraceptives) before randomization until the end of the follow-up period.

  • Subjects must have a diagnosis of Celiac Disease confirmed by duodenal / jejunal biopsy or by capsule endoscopy plus positive celiac serology test results =12 months before study entry.

  • Subjects with a positive serum anti-tTG (IgA or IgG) OR deamidated gliadin peptide (anti-DGP—IgA or IgG) antibodies as determined by screening serology.

  • Subjects with CeD-GSRS score of = 2.0 at screening AND at the end of placebo run-in phase prior to randomization.

  • During one month prior to the screening visit, subjects must have had one of the following symptoms at least once per week or four times during the month: diarrhea, abdominal pain, bloating, nausea or stomachache.

  • Subjects must be willing to return for all scheduled study visits.

  • Subjects must be willing to refrain from illicit drug use and alcohol abuse throughout the duration of the study.

EXCLUSION:
  • Subjects with Refractory Celiac Disease (RDC) Type 1 or Type 2 or severe complications of Celiac Disease (including, but not limited to, Enteropathy-associated T cell Lymphoma–EATL, ulcerative jejunitis, perforation, severe osteoporosis or malnutrition or any other severe complication of CeD).

  • Subjects suspected to have lymphoma or any other serious complications of Celiac Disease (special caution should be exercised in including subjects >50 years of age to exclude RCD and EATL, by the standard methods used at the site).

  • Subjects diagnosed with any chronic active GI disease other than Celiac Disease (e.g. Crohn’s Disease, Ulcerative Colitis, active Irritable Bowel Syndrome, microscopic colitis, active lactose intolerance, active Gastroesophageal Reflux Disease (GERD) not controlled by H2 blockers –H2 receptor antagonists), following diagnostic procedures that are standard at the site.

  • Subjects with diabetes (Type 1 or Type 2) or other autoimmune diseases that might interfere with the conduct of the study, such as autoimmune hepatitis, primary biliary cirrhosis, multiple sclerosis and systemic lupus erythematosus.

  • Subjects with known untreated small intestinal bacterial overgrowth (SiBo).

  • Subjects with significant co-morbid disease that by the investigators determination would make the subject unsuitable for enrollment, including unstable medical conditions (chronic obstructive pulmonary disease, angina, severe cardio-respiratory conditions, etc.).
