Clinical Trial Summary

The main objective is to evaluate the efficacy of Azéol Spray Nasal, taken two times a day, versus placebo on nasal congestion in subject with common cold.

Description:

This study is designed as a multicentric, randomized, double-blind, placebo-controlled with two-arm parallel groups clinical trial. 144 subjects presenting with early symptoms of common cold will be recruited for this study, according to the defined inclusion and exclusion criteria. The main objective is to evaluate the efficacy of Azéol Spray Nasal (Bifidobacterium breve LA 708, extract of cypres Cupressus sempervirens L., extract of Leguminosae Glycyrrhiza glabra L., glycerin and mannitol), taken two times a day, versus placebo on nasal congestion in subject with common cold.
