Outcomes

Primary Outcome Measures

Proportion of patients achieving a histological response in the stomach and/or in the duodenum
Given the decision to stop recruitment to the study, it will not be possible to assess objectives with the data collected during Part A.
Absolute change from baseline in SAGED (Symptom Assessment for Gastrointestinal Eosinophilic Diseases) Score (range: 0-50). SAGED score measures gastrointestinal symptoms with higher scores meaning worse outcome
Given the decision to stop recruitment to the study, it will not be possible to assess objectives with the data collected during Part A.

Secondary Outcome Measures

Percent change in tissue eosinophils
Given the decision to stop recruitment to the study, it will not be possible to assess objectives with the data collected during Part A.
Proportion achieving treatment response
Given the decision to stop recruitment to the study, it will not be possible to assess objectives with the data collected during Part A.
Diarrhea-free days
Given the decision to stop recruitment to the study, it will not be possible to assess objectives with the data collected during Part A.
Frequency of diarrhea episodes
Given the decision to stop recruitment to the study, it will not be possible to assess objectives with the data collected during Part A.
Vomiting-free days
Given the decision to stop recruitment to the study, it will not be possible to assess objectives with the data collected during Part A.
Frequency of vomiting episodes
Given the decision to stop recruitment to the study, it will not be possible to assess objectives with the data collected during Part A.
Proportion of patients with no rescue corticosteroid use
Given the decision to stop recruitment to the study, it will not be possible to assess objectives with the data collected during Part A.
Health-related quality of life measured as change from baseline in SF-36v2 (the Short Form 36-item Health Survey, Version 2) which has two components: Physical Component Summary (PCS) and Mental Component Summary (MCS).
The score range for PCS and MCS is 0-100; higher scores indicate better health state. Given the decision to stop recruitment to the study, it will not be possible to assess objectives with the data collected during Part A.
Diarrhea and constipation free days
Given the decision to stop recruitment to the study, it will not be possible to assess objectives with the data collected during Part A.
Clinically meaningful symptom change. Time to clinically meaningful change in SAGED score (range: 0-50) measures gastrointestinal symptoms with higher scores meaning worse outcome.
Given the decision to stop recruitment to the study, it will not be possible to assess objectives with the data collected during Part A.
PROMIS Fatigue 7a score
Given the decision to stop recruitment to the study, it will not be possible to assess objectives with the data collected during Part A.
PAGI-QoL score
Given the decision to stop recruitment to the study, it will not be possible to assess objectives with the data collected during Part A.
PAGI-SYM score
Given the decision to stop recruitment to the study, it will not be possible to assess objectives with the data collected during Part A.
Pharmacokinetics of benralizumab in patients (with EG/EGE)
Given the decision to stop recruitment to the study, it will not be possible to assess objectives with the data collected during Part A.

Intervention Type
Biological
Intervention Name(s)
Benralizumab
Other Intervention Name(s)
Fasenra
Intervention Description
Benralizumab is a humanized, afucosylated, monoclonal antibody that binds specifically to the IL-5Rα on the target cell and thus directly depletes eosinophils through antibody-dependent cell-mediated cytotoxicity. Benralizumab has been widely approved for treatment of asthma.
Intervention Type
Biological
Intervention Name(s)
Placebo
Intervention Description
Placebo will be injected as a comparator to injection with Benralizumab to examine effect on both the signs and symptoms of EG/EGE and the underlying eosinophilic inflammation, with dual primary outcome variables
