Study Overview
Brief Summary
To assess multiple doses of ZED1227 capsules vs placebo for efficacy in: Improvement of celiac disease symptoms as assessed by Celiac Disease Symptom Diary (CDSD) in celiac disease subjects experiencing symptoms and having mucosal damage on a gluten-free diet.
Eligibility Criteria
- Ages
- 18 years to 65+ years (18-64 Years, 65+ Years)
- Accepts Healthy Volunteers
- Yes
Inclusion Criteria
- •Signed informed consent
- •Willingness to follow her/his usual dietary patterns, including eating at restaurants and others’ homes during the trial

The investigator is responsible for determining whether the subject has adequate birth control for trial participants
- •Men or women between 18 and 80 years of age, inclusively

- •At least one moderate or severe gastrointestinal symptom (i.e., diarrhoea, abdominal pain, bloating, or nausea) during the last 4 weeks prior to Baseline Visit A and last 3 weeks prior to Baseline Visit B as a GI total mean symptom score (measured using CDSD) for the worst 25% of the days of ≥ 2 on a 5-point scale. The interval between Screening Visit and Baseline Visit A must be at least 28 days. If the interval is less than 28 days, this inclusion criterion is not met,

Exclusion Criteria
- •Presence of hypo- or hyperthyroidism. A patient with a thyroid stimulating hormone (TSH) level up to 25% higher than ULN or up to 25% lower than the lower limit of normal (LLN) but with normal free triiodothyronine (FT3) and free thyroxine (FT4) levels can be included in the trial. In addition, a patient with a well-controlled thyroid disorder during the previous 3 months can be included
- •Abnormal hepatic function (alkaline aminotransferase [ALT] or alkaline phosphatase [ALP] > 2.5 x ULN), liver cirrhosis, or portal hypertension
- •Glomerular filtration rate ≤ 60 ml/min/1.73 m²
- •Continuous intake of systemic (oral or intravenous) corticosteroids or immunomodulators (e.g., glucocorticoids, cyclosporine, methotrexate, anti-TNF- therapy, anti-integrin therapy, Janus kinase inhibitors), high dose inhaled corticosteroids (> 1000 µg/d of beclomethasone dipropionate or equivalent) during the past 3 months before V0
- •Continuous intake of drugs with suspicion of impact on villous atrophy, such as • proton-pump inhibitors (PPIs; permitted at a regular dose equivalent to 20-40 mg/day pantoprazol, esomeprazole or equivalent), • selective serotonin reuptake inhibitors (SSRIs; low to medium dose [10-150 mg Fluvoxamine or equivalent dose of other SSRIs] permitted in case of long-term therapy [at least for 6 months]), • losartan (angiotensin II receptor blockers equivalent to 50 mg losartan permitted except for olmesartan forbidden at any dose) and • mycophenolate1,2 (forbidden at any dose) during the past 2 months before biopsy sampling in Trial Period A; • non-steroidal anti-inflammatory drugs (NSAIDs; maximal daily dose permitted 900 mg for ibuprofen, 500 mg for naproxen and 75 mg for diclofenac, except for one week before biopsy) and • acetylsalicylic acid (max daily dose permitted 100 mg) during the past 4 weeks before biopsy sampling at Baseline Visit A
- •Alcohol use > 12 g/d for women, > 24 g/d for men within the past 12 months before screening
- •Dual antiplatelet therapy (i.e., acetylsalicylic acid in combination with thienopyridines [clopidogrel, prasugrel, ticlopidine or ticagrelor]) or oral anticoagulants (i.e., warfarin, dabigatran, etexilate, rivaroxaban, apixaban)
- •Unwillingness to undergo upper gastrointestinal endoscopy with biopsy at Baseline Visit A and Final/Withdrawal Visit
- •Unwillingness to ingest SIGE bars through run-in and treatment period
- •Food allergies to nongluten ingredients (tapioca syrup, oats, almonds, rice crisp, chocolate, almond butter, cocoa butter, oat flour, glycerine, sunflower lecithin, salt, and natural flavours) of the SIGE bar or significant symptoms upon ingestion of the gluten-free SIGE bar
- •Known hypersensitivity reaction and/or allergy, including anaphylaxis, to wheat and/or gluten
- •Patients diagnosed to have confirmed refractory celiac disease type I (RCDI) or II (RCDII), with the exception that patients with a diagnosis of RCDI can be considered for inclusion if they do not have clear signs of T cell monoclonality or atypical T cells (e.g., as revealed by CD3/CD8 immunohistochemistry) and if they do not present with very severe symptoms and/or parameters of significant malabsorption and if they have not received prior treatment with immunosuppressants such as budesonide or azathioprine

- •History or presence of dermatitis herpetiformis
- •History or presence of neurological disorders like ataxia or neuropathy (mild neuropathy, related or unrelated to celiac disease, is not a reason for exclusion)
- •Any severe concomitant cardiovascular, renal, endocrine (type 1 diabetes mellitus with HbA1C > 8% / 64mmol/mol or hospitalisation or emergency visit for hyperglycaemia or hypoglycaemia within 12 months of screening), or psychiatric disorder or other disease, which in the opinion of the investigator might have an influence on the subject’s compliance or the interpretation of the results
- •Any prior invasive malignancy diagnosed within the last 5 years prior to Screening visit. Patients with basal cell carcinoma of the skin completely resected can be included.
- •Evidence of relevant systemic disease (e.g., active tuberculosis)
