Eligibility |
Inclusion Criteria: - Well-documented medical history of Eosinophilic Esophagitis after ingestion of milk and currently following a strict milk-free diet. - Upper endoscopy and biopsy at initial clinical evaluation during Visit 2 showing greater than 15 eosinophils/high power field (HPF) isolated to the esophagus meeting the consensus diagnosis of Eosinophilic Esophagitis, after milk was re-introduced into the subject's diet (30 ml/day for 1 week to 2 months), while the subject was on proton pump inhibitor. - Upper endoscopy and biopsy at second clinical evaluation during Visit 3 showing less than 5 eosinophils per HPF isolated to the esophagus after a minimum of 6 weeks under milk-free diet, and while the subject is on proton pump inhibitor. - Negative pregnancy test for female subjects of childbearing potential. Females of childbearing potential must use effective method of contraception to prevent pregnancy and agree to continue to practice an acceptable method of contraception for the duration of participation in the study. Sexual abstinence will be accepted as an effective method of contraception for girls below 18 years of age. - Subjects and/or parents/guardians willing to comply with all study requirements during their participation in the study. - Signed informed consent from parent(s)/guardian(s) of children < 18 years + children's assent. - Subjects agree to maintain a constant diet during the trial, with the exception of milk. - Subjects will maintain constant medications for asthma and allergic rhinitis during the trial. Exclusion Criteria: - Subjects with a history of severe anaphylaxis to milk with the following symptoms: hypotension, hypoxia, neurological compromise (collapse, loss of consciousness or incontinence), Quincke Edema or requiring intubation. - Active IgE- mediated milk allergy. - Pregnancy or lactation. - Subjects with other eosinophilic gastrointestinal disorders. - Subjects on swallowed corticosteroids or anti-leukotrienes for Eosinophilic Esophagitis. - Subjects with symptomatic allergy to pollens whose symptoms during the corresponding pollen season might interfere with the recording of symptoms during the upper endoscopy/biopsy, if the upper endoscopy/biopsy is conducted during the pollen season. The Investigator will have to ensure that the period for conducting the upper endoscopy for such a subject will be outside of the pollen season. - Subjects treated with systemic long-acting corticosteroids (depot corticosteroids) within 12 weeks prior to Visit 1 and/or systemic short-acting corticosteroid within 4 weeks prior to Visit 1 or any systemic corticosteroid at screening. - Subjects with asthma conditions defined as follows: 1. Uncontrolled persistent asthma by National Asthma Education and Prevention Program Asthma guidelines (2007). 2. at least two systemic corticosteroid courses for asthma in the past year or one oral corticosteroid course for asthma in the past three months; 3. prior intubation for asthma in the past two years. - Subjects on ß-blocking agents, angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, calcium channel blockers or tricyclic antidepressant therapy. - Subjects undergoing any type of immunotherapy to any food within one year prior to Visit 1. - Subjects presently on aeroallergen immunotherapy and unwilling or unable to discontinue. - Subjects currently treated with anti-tumor necrosis factor drugs or anti-Immunoglobulin E (IgE) drugs or any biologic immunomodulatory therapy within one year prior to Visit 1. - Allergy or known hypersensitivity to placebo excipients either of the Viaskin® or Tegaderm®. - Subjects suffering from generalized dermatologic diseases with no intact skin zones to apply the Viaskin®, or urticarial and mast cell disorders such as chronic idiopathic urticaria. - Subjects (or parents of subjects) with obvious excessive anxiety and unlikely to cope with the conditions of an upper endoscopy and biopsy. - Past or current disease(s), which in the opinion the sponsor-investigator, may affect the subject's participation in this study including but not limited to active autoimmune disorders, immunodeficiency, malignancy, uncontrolled diseases (hypertension, psychiatric (especially anxiety), cardiac), or other disorders (e.g., liver, gastrointestinal, kidney, cardiovascular, pulmonary disease, or blood disorders). - Any history of drug or alcohol abuse in the past five years. - Subjects unable to follow the protocol and the protocol requirements. - Participation in another clinical intervention study in the three months prior to Study Visit 1. - Subjects on any experimental drugs or treatments. |

Primary | Change in Maximum Esophageal Eosinophil Count From Baseline to End of Double-blind Treatment. (Intent to Treat Population) | Esophageal biopsy samples will be obtained prior to randomization and after completion of treatment. Intraepithelial eosinophils will be counted in all high powered fields (HPFs) using light microscopy. A HPF will be counted only if at least half of the field is occupied by tissue. The maximum eosinophil count per HPF will be reported for each esophageal biopsy site (at each of 2 levels). The maximum eosinophil count for each patient will be calculated from either level. For the final outcome, mean from each individual patients maximum eosinophil count/hpf along with standard deviation will be calculated. |
From baseline to month 11 (end of double blind phase) | |
Primary | Change in Eosinophils/High Power Field at End of Double-blind (DB) (Per Protocol Patients) | Esophageal biopsy samples will be obtained prior to randomization and after completion of treatment. Intraepithelial eosinophils will be counted in all high powered fields (HPFs) using light microscopy. A HPF will be counted only if at least half of the field is occupied by tissue. The maximum eosinophil count per HPF will be reported for each esophageal biopsy site (at each of 2 levels). The maximum eosinophil count for each patient will be calculated from either level. For the final outcome, mean from each individual patients maximum eosinophil count/hpf along with standard deviation will be calculated. |
Month 11(end of double blind phase) | |
Secondary | Eosinophilic Esophagitis Symptom Score (Intent to Treat Population) | Symptoms of Eosinophilic Esophagitis range from abdominal pain, gastroesophageal reflux, vomiting, and difficult swallowing. Investigator assessment of the subject's symptoms was completed on a 4-point Likert scale for 3 separate symptoms (vomiting, abdominal pain and dysphagia). Investigator assessment of the subject's symptoms was completed on a 4-point Likert scale for 3 separate symptoms (vomiting, abdominal pain and dysphagia). (0-none, 1-mild, 2-moderate, 3-severe, ). Total score is reported with a range of 0 to 9. A lower score is better. |
Total Symptom Score at End of DB Phase, Month 11 | |
Secondary | Esophageal Endoscopy Score (ITT) | Upper endoscopies with biopsies (2 each of proximal and distal, plus any inflamed areas) will be completed before and after each treatment period. Each endoscopy will be scored using a validated standardized measure which examines 4 major esophageal features (rings, furrows, exudates and edema) and the presence of minor features of narrow caliber esophagus, feline esophagus, stricture and crepe paper esophagus. Each feature is graded: 0-none, 1 mild, 2-moderate, 3-severe. The scores are summed including both minor and major criteria. Total score is presented and lower score is better. The range is from 0-12 |
At end of DB phase, at 11 months | |
Secondary | Eosinophils Per HPF at End of Double Bind Protocol (Per Protocol) Patients | Maximum Eosinophils/HPF after milk reintroduction at the end of double bind phase | End of DB Phase, at 11 months | |
Secondary | Pediatric Eosinophilic Esophagitis Symptom Score (ITT) | Measure of Pediatric Eosinophilic Esophagitis symptom Score (PEESS) at the end of DB phase for the Intent to Treat Population The PEESS® is a 20 question survey asking patient symptom intensity and frequency on a 5 point scale (0 to 4) for each question for the preceding month. Therefore, the total score can range from 0 to 80. The total score is reported and lower score is better | Month 11, end of Double Blind Phase | |
Secondary | Endoscopy Score (Per Protocol Patients) | Upper endoscopies with biopsies (2 each of proximal and distal, plus any inflamed areas) will be completed before and after each treatment period.
