|Official Title:||Investigating the Role of a4b7 Integrin as a Therapeutic Target in Eosinophilic Esophagitis|
|Study Start Date :||March 2016|
|Estimated Primary Completion Date :||July 2018|
|Estimated Study Completion Date :||December 2018|
Adults with EoE
Adult patients with active eosinophilic esophagitis will under blood collection and esophagus biopsies in order to perform eosinophil isolation and characterization.
Other: Eosinophil isolation and characterization.
Peripheral blood and esophageal biopsies will be obtained from study subjects for further analysis of eosinophils integrin profiles.
- Percentage of eosinophils expressing a4b7 integrin [ Time Frame: 8 weeks ]Eosinophil expression levels of a4b7 integrin will be assessed on peripheral and esophageal eosinophils during active EoE and after treatment-induced remission.
Biospecimen Retention: Samples With DNA
