Search Clinical Trials

Trial Objectives


Researchers want to know if cells of the skin, airway and esophagus are different in people who have and those who don’t have allergic conditions. The goal is to understand if areas of the body that are exposed to environmental particles, from inhaling or touching them, contribute to the development of asthma, eczema, food allergies, eosinophilic esophagitis (EoE) and GERD (gastroesophageal reflux disease). The study requires samples of the skin, airways and esophagus.
