Official Title: Evaluation of ColdZyme® on Experimentally Induced Common Cold. -A Double-blind, Randomized, Placebo-controlled Study in Healthy Volunteers.
Brief Summary: This study evaluates the performance of ColdZyme® mouth spray on prevention of common cold symptoms on experimentally induced rhinovirus upper respiratory tract infection in healthy volunteers. Half of participants will receive ColdZyme® mouth spray while the other half will receive placebo.
Detailed Summary: 88 subjects will be inoculated with rhinovirus 16 via the nasal route. The subjects will be randomized 1:1 to ColdZyme® or placebo. Treatment (6 doses per day) will be applied for 11 days from the day of inoculation. The subjects will visit the investigational clinic on 6 occasions. During these visits the subjects will leave nasal (lavage) and pharyngeal (swab) samples for quantification of virus replication. All subjects will have a diary for scoring of cold symptoms.
