Summary description of the study

In the study, participants are randomly assigned (like flipping a coin) to treatment with ZED1227 or placebo. The placebo looks like ZED1227 but contains no active ingredient. While participants take ZED1227 or placebo, they consume a snack bar containing a small amount of gluten three times a week (much less than is found in a slice of bread). The researchers want to investigate whether the drug helps even when patients inadvertently consume gluten through their normal diet. The consumption of these snack bars is referred to as simulated inadvertent gluten exposure (SIGE). The comparison between the patient group treated with ZED1227 and the placebo group will help researchers determine whether ZED1227 can alleviate the symptoms of celiac disease.
