A Pivotal Study to Assess the Effectiveness of Nasal Dilator (Breathe Right Nasal Strips)

Study Overview
=================
Brief Summary
-----------------
This randomized, double-blind, parallel group, placebo-controlled study assessed subjective measures of nasal airway breathing immediately after application in the morning upon awakening after use of breathe right nasal strips (BRNS). Participants who met the entrance criteria, were currently suffering from nasal congestion, reported trouble with their sleep and had baseline nasal openness scores at bedtime during the qualification phase of ≤ 70 on a 100-point Visual Analogue Scale (VAS) on at least four of seven qualification nights were randomized to one of two treatments for use at home. Participants returned to the study site after 7 and 14 days of nightly nasal strip use, respectively. At the two return visits, a validated subjective questionnaire, the Nocturnal Rhinoconjunctivitis Quality of Life Questionnaire (NRQLQ), measured response.

Detailed Description
-----------------
The study had a screening phase, a one-week baseline qualification and a two-week treatment phase. Participants who met the entrance criteria, who were currently suffering from nasal congestion every night or almost every night, reported trouble with their sleep and had baseline nasal openness scores at bedtime during the qualification phase of ≤ 70 on a 100-point VAS on at least four of seven qualification nights were randomized to one of two treatments for use at home. During the two-week in-home treatment phase, daily diaries measuring the perception of nasal breathing and nasal congestion using a VAS were completed. Participants returned to the study site after 7 and 14 days of nightly nasal strip use, respectively. At the two return visits, a validated subjective questionnaire, the NRQLQ, measured response.
