a study to evaluate the safety and use of human rhinovirus in healthy and asthmatic participants (mk-0000-218)

Conditions: Asthma

Summary: the purpose of this study is to establish the safety and tolerability of unbiased biomarkers for the prediction of respiratory disease outcomes (u-biopred) human rhinovirus 16 (rv16ub) in healthy and asthmatic participants, and to identify an appropriate dosage of rv16ub in order to study biomarkers in asthmatic participants. the study is divided into 2 parts. part 1 is a dose-finding study where healthy participants, and asthmatic participants, who were either treated or not treated with a class of long-acting beta antagonists (laba) will be recruited to undergo nasal challenge with increasing doses of rv16ub. part 2 is a biomarker study where mild to moderate asthmatics undergo challenge with the most appropriate dose of rv16ub identified in part 1, based on tolerability and viral effects. .
