Study Endpoints
Primary Endpoints
Absolute Change From Baseline in Celiac Disease Patient-Reported Outcome Abdominal Symptoms Domain Score Through Week 24
Baseline (average of Day -7 to Day -1) up to Week 24

The CeD PRO questionnaire was captured daily in the eDiary. The questionnaire included 9 items: abdominal cramping, abdominal pain, bloating, gas, diarrhea, loose stool, nausea, headache and tiredness. Participants were asked to rate their symptom severity on an 11-point scale and scores range from 0 (not experiencing the symptom) to 10 (the worst possible symptom experience). Abdominal Symptoms domain included abdominal cramping, abdominal pain, bloating and gas. Total score for abdominal symptoms domain range from 0 to 40. Higher scores indicated worse outcome. Baseline abdominal symptoms domain score was defined as the average of the daily scores for the last week of the placebo run-in period.
