Histological remission and dysphasia symptom response with EOHILIA were studied in two 12-week clinical studies that included 410 patients1
Study 1: Phase 3 study evaluated the efficacy and safety profile of EOHILIA vs placebo in 318 patients with EoE, 11 to 56 years old; treatment randomization: 2:1 for EOHILIA 2 mg b.i.d. or placebo.1,2
Study 2: Phase 2 study evaluated the efficacy and safety profile of EOHILIA vs placebo in 92 patients with EoE, 11 to 42 years old; treatment randomization: 1:1 for EOHILIA 2 mg b.i.d. or placebo.1,3
Efficacy Endpoints
- Histological remission: proportion of subjects achieving histological remission defined as a peak eosinophil count of ≤6 eos/hpf across all available esophageal levels1
- DSQ scores: absolute change from baseline in subject-reported DSQ combined score.1 The DSQ was a questionnaire developed and validated to specifically measure dysphagia associated with EoE4
Key Inclusion Criteria1-3,5
- Esophageal inflammation, defined as peak eosinophil
count ≥15 eos/hpf from at least 2 levels of the esophagus - ≥4 days of dysphagia over a 2-week period prior to
randomization, as measured by the DSQ - Non-responsiveness to 6 to 8 weeks of high-dose PPI
therapy
Key Exclusion Criteria1-3,5
- Use of swallowed topical corticosteroids for EoE or
systemic corticosteroids for any condition ≤4 weeks
before screening - Pure liquid or six-food elimination diet (SFED)*
- Use of CYP3A4 inhibitors
- Presence of a high-grade esophageal stricture
*In Study 1, subjects were excluded if they were on a full-liquid or six-food elimination diet. In Study 2, subjects were instructed to maintain a stable diet throughout the study.1
b.i.d.=twice daily; DSQ=Dysphagia Symptom Questionnaire; eos/hpf=eosinophils per high-power field; PPI=proton pump inhibitor.
