Assessing the Safety of an IGY Supplement on the Gut Microbiome

Use of regular prescription medications, including antihypertensives, anti-inflammatory drugs, corticosteroids, immunosuppressants, antidepressants, antipsychotics, anti-diabetic medications, and anti-arrhythmic agents, which in the opinion of the investigator, would adversely affect study safety or outcome.

Prior gastrointestinal disease, surgery, or radiation treatment which, in the Investigator's opinion, would lead to intestinal structuring or obstruction with a risk of capsule non-excretion, including, e.g., achalasia, eosinophilic esophagitis, cancer diagnosis or previous esophageal, gastric, small intestinal, or colonic surgery. Appendectomy or cholecystectomy more than 3 months before the screening visit is acceptable.

History of known structural gastrointestinal abnormalities such as structures or fistulas which may lead to mechanical obstruction.

Use of any medications in the week prior to the SIMBA or LIMBA capsule ingestions, unless part of regular treatment, that could substantially alter gastrointestinal motor function (e.g., opioids, anticholinergics, GLP-1 analogues); laxative and prokinetic use is allowed if it is kept unchanged in the week prior to the SIMBA and LIMBA capsule ingestions. Proton pump inhibitors (PPIs) are allowed provided a wash-out period of 48 hours is respected before swallowing the capsules and PPI treatment is resumed only 4 hours thereafter.
