|---|---|---|---|
| Primary | Change From Baseline in Mean Number of Peak Eosinophils (Eos) Count Per High-power Field (Hpf) in Gastrointestinal (GI) Biopsies | Baseline and Week 16 | Blood samples were collected to assess eosinophils count. Baseline data are defined as last measurement collected on or prior the date of first dose for Induction Phase. |
| Secondary | Induction Phase: Changes in Each of 5 Domain Scores of the Izumo Scale From Baseline at Week 16 | Baseline and Week 16 | The Izumo Scale questionnaire assesses the comprehensive 5 different GI symptom domains during the past week and consists with 15 weekly questions (3 questions per 1 domain): Heartburn Symptoms domain(Questions1 through3), Gastric Pain Symptoms domain(Questions4 through6), Stomach Heaviness Symptoms domain(Questions7 through9), Constipation Symptoms domain (Question 10 through12), Diarrhea Symptoms domain (Questions13 through15). Each question is scored on a 6-point Likert scale of "0 = No trouble at all" to "5 = Can't stand it," and the score for each question within a domain is added to determine domain specific scores scaled from 0 to 15, with higher values indicating greater symptom severity. |
| Secondary | Induction + Maintenance: Changes in Each of 5 Domain Scores of the Izumo Scale From Baseline at Week 48 | Baseline and Week 48 | The Izumo Scale questionnaire assesses the comprehensive 5 different GI symptom domains during the past week and consists with 15 weekly questions (3 questions per 1 domain): Heartburn Symptoms domain(Questions1 through3), Gastric Pain Symptoms domain(Questions4 through6), Stomach Heaviness Symptoms domain(Questions7 through9), Constipation Symptoms domain (Question 10 through12), Diarrhea Symptoms domain (Questions13 through15). Each question is scored on a 6-point Likert scale of "0 = No trouble at all" to "5 = Can't stand it," and the score for each question within a domain is added to determine domain specific scores scaled from 0 to 15, with higher values indicating greater symptom severity.
