The ITN article that reported the results of the CATEEC clinical trial, which compared clinical and biological responses to cat allergen exposure by nasal allergen challenge (NAC) or environmental exposure chamber (EEC) was selected to be an Editors’ Choice feature and was displayed on the American Academy of Allergy Asthma & Immunology (AAAAI) website.
The original article was published in The Journal of Allergy & Clinical Immunology (JACI) in March. It reported that while there were differences, that the immunological responses were similar, suggesting that both methods were valid options and that the selection of a method for allergen challenge should be based on the specific considerations of the study.
