A Six Month, Safety Follow-up Study in Eosinophilic Esophagitis Subjects Who Completed Study PR-021

This study has been completed.

Forest Laboratories Identifier:
First received: December 16, 2011
Last updated: February 8, 2017
Last verified: February 2017

This purpose of this study is the long-term follow-up of glucocorticosteroid-related adverse events and hypothalamic-pituitary-adrenal axis (HPA) suppression in subjects after discontinuation of study drug received in the PR-021 study (Safety and Tolerability Study of Oral EUR-1100 to Treat Eosinophilic Esophagitis). The study will also provide the opportunity to better understand the natural course of eosinophilic esophagitis and define the treatment modalities of eosinophilic esophagitis with EUR-1100, such as the need for chronic maintenance or intermittent treatment.

All subjects who complete PR-021 will be offered the opportunity to participate in this study. The duration of this follow-up study is six months, during which subjects will visit the clinic for safety evaluation and clinical symptom assessment at the screening, Week 8, Week 16, and Week 24 visits. Additional phone visits will occur at Week 4, Week 12, and Week 20.

Groups/Cohorts Assigned Interventions
PR-021 Eosinophilic Esophagitis (EoE) Subjects
Subjects who received study drug and completed PR-021 study
Drug: EUR-1100 Drug: Placebo


Ages Eligible for Study:   12 Years to 55 Years   (Child, Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Subjects who received study drug and completed the PR-021 study (Safety and Tolerability Study of Oral EUR-1100 to Treat Eosinophilic Esophagitis)

Inclusion Criteria:

  • Subject completed full participation in Study PR-021 (Subjects discontinued prematurely from PR-021 due to HPA axis suppression will be eligible for study PR-022)
  • Written informed consent (parent or legal guardian must sign when applicable) and assent form, if required
  • Willing and able to adhere to all study procedures

Exclusion Criteria:

  • Subjects already requiring medications or procedures for the treatment of EoE at the time of enrollment into the follow-up study, such as systemic (oral or parenteral) or inhaled corticosteroids, esophageal dilation, Proton Pump Inhibitors (PPIs) and/or dietary restrictions; in the case of subjects already on PPIs and /or dietary restrictions during Study PR-021, only subjects requiring an increase in dosage of PPIs and/or new dietary restrictions because of worsening of symptoms will be excluded
  • Any physical, mental, or social condition, history or concurrent illness or laboratory abnormality that, in the investigator's judgment, might interfere with study procedures or the ability of the subject to adhere to and complete the study
  • Contraindication to esophagogastroduodenoscopy (EGD) or esophageal biopsy or narrowing of the esophagus precluding EGD
  • Female subjects who are pregnant or breastfeeding
  • Participation in a clinical study involving an investigational drug or investigational device
