[0081] method

[0082] Research design

[0083] The feasibility and efficacy of EPIT in the treatment of eosinophilic esophagitis (EE) was evaluated in a mouse model of peanut sensitization. After the sensitization phase, animals were divided into 2 groups: untreated group (NT group) and treated group, which was treated once a week through the epidermis using the epidermal delivery system further described (EPIT) for a total time course of 8 week. The control group (C) also consisted of unsensitized animals. Blood was sampled for analysis at the beginning and end of the experiment and histological analysis after oral challenge with peanut allergen.

[0084] Animal and Protein Extracts

[0085] Four-week-old female BALB / c mice (n=30) purchased from Charles River Laboratories (France) were sensitized to peanut protein. The use of BALB / c mice as a murine model for peanut protein sensitization is described in Adel-Patient et al., 2005. This model should reproduce the goo...

Abstract

The present invention relates to the treatment of EE. More specifically, the invention relates to a new method of treating EE through the epicutaneous route. In particular, the method of the invention comprises applying to the skin of the subject a skin patch device, comprising a composition, under conditions allowing a contact between said composition and the skin. The present invention also relates to the skin patch device and to a use of the skin patch device in the manufacture of a composition for treating eosinophilic esophagitis in a subject.

Description

technical field [0001] The present invention relates to the treatment of eosinophilic esophagitis (EE). More specifically, the present invention relates to novel methods of treating EE via the epidermal route. Specifically, the methods of the present invention comprise applying a skin patch device comprising a composition to the skin of a subject under conditions that permit contact between the composition and the skin. The invention also relates to a skin patch device and the use of said skin patch device in the manufacture of a composition for treating eosinophilic esophagitis in a subject. Background technique [0002] Eosinophilic esophagitis (EE) is characterized by eosinophilic infiltration of the esophagus (1). EE has become increasingly common, according to studies in the United States, Switzerland, and Australia (2). For example, at The Children's Hospital of Philadelphia, there was a 35-fold increase from 2 cases in 1994 to 72 cases in 2003 (3). [0003] Sympto...
