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

GlaxoSmithKline130 enrolled

Overview

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.

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.

Participant must have discontinued use of the following products according to the timings specified below: a) Prior to initiation of the baseline qualification phase: i. Use of any substance with psychotropic effects or properties known to affect sleep/wake, including but not limited to: neuroleptics, morphine/opioid derivatives, sedative antihistamines, stimulants, antidepressants, clonidine, barbiturates, anxiolytics, thalidomide, hypnotics and sedatives. Use of over-the-counter (OTC) sleep promoting agents including diphenhydramine, doxylamine, tryptophan, valerian root, kava kava, melatonin, St John's Wort and Alluna. Use of OTC alertness aids including caffeine and guarana. ii. Lubricating sprays/rinses/throat strips iii.

Primary Outcomes

Change From Baseline in Mean Average Score of Nocturnal Rhinoconjunctivitis Quality of Life Questionnaire (NRQLQ) for Each Domain Problems (Sleep, Sleep Time, Symptoms on Waking in the Morning, and Practical Problems) at Day 7

Participants scored all the domains of NRQLQ using same 7 points scales where 0=Not troubled and 6=extremely troubled. Domains: Sleep problems (difficulty getting sleep, unable to get a good night sleep or wake up during the night, restless \[tossing and turning\] and having to get up because stuffy nose or to blow nose using the score, scores range: Min-Max \[0-24\]); Sleep time problems (Nasal congestion or stuffy nose, sinus pressure or pain, runny nose, post-nasal drip \[drainage down back of nose/throat\], and headache, scores range: 0- 30); Symptoms on waking in the morning (Feel tired and unrefreshed, nasal congestion or stuffy nose, congestion in sinuses, takes time to clear nighttime drainage after waking up, scores range:0-24); practical problems (have to avoid symptom triggers (such as dust, cigarette smoke, strong smells and perfumes), need to rub nose or eyes, and have to take medication, scores range: 0-18). Lower scores indicate improvement in the rhinitis symptoms.
