Comparability and Standardization of Controlled Allergen Challenge Facilities
In Brief
A Phase 4 clinical trial evaluating Cetirizine and Placebo for Allergic Rhinitis. Completed, enrolled 98 participants across 2 sites in 2 countries.
Detailed Summary
Allergen challenge facilities have been utilized for many years in clinical drug trials studying onset of action, proof of concept, duration of action, and efficacy. Each facility has somewhat different design characteristics and pollen dispersal technologies. Facilities are located in disparate geographic areas and have populations of participants who are sensitized to allergens unique to that area. Therefore, facilities have operated as single sites with little effort to evaluate facility comparability or to attempt standardization across facilities. The purpose of this study is to compare the two sites and assess whether the sites are able to achieve similar symptom scores.
