- Willingness to follow her/his usual dietary patterns, including eating at restaurants and others’ homes during the trial
- Willingness to maintain current GFD throughout participation in the trial
- Negative pregnancy test in female subjects under 60 years of age at Screening Visit and Baseline Visit B
- Women of child-bearing potential should use a highly effective method of birth control which is defined as those which result in a low failure rate (i.e. less than 1% per year) when used consistently and correctly, such as implants, injectables, combined oral contraceptive pills, combined contraceptive patches and vaginal rings, copper containing intrauterine devices, sexual abstinence or vasectomised partner (see Table 11 for further information on acceptable and unacceptable birth control methods). The investigator is responsible for determining whether the subject has adequate birth control for trial participants

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
- 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

- 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
- If more than 10% of planned enrolled subjects report a greater than 1 point improvement in PGI-S during Trial Period A, further subjects with > 1 point improvement in PGI-S will be excluded
- Known intolerance/hypersensitivity/resistance to the investigational medicinal product (IMP) and excipients or drugs of similar chemical structure or pharmacological profile
