Trial Outcomes & Findings for To Characterize the Performance of the Nasal Dilator Strip in Lowering Nasal Resistance During Sleep, Promoting Nasal Route Breathing and Reducing the Signs and Symptoms of Sleep Disordered Breathing in a Group of Chronic Nocturnal Nasal Congestion Sufferers Who Report Trouble With Their Sleep. (NCT NCT03105297)

NCT ID: NCT03105297

Last Updated: 2019-07-26

Results Overview

Measure
All Participants
The study consisted of 3 phases: baseline phase, 28 days active phase followed by a two-night cross-over nasal resistance phase. In the baseline phase all the participants applied nasal dilator strip during the sleep laboratory night on Day 1. During the active phase participants wore nasal dilator strip over a 1-month in-home use period and returned for sleep laboratory nights after 7 days (on Day 8) and 28 days (on Day 29) of treatment. The nasal resistance phase consisted of 2 sleep laboratory nights (Day 30 and 31), where the participants were randomized to receive a sequence of either 'strip'/' no strip' or no strip'/'strip' as per the randomization schedule

Nasal resistance was measured on Day 1, by a modified method of posterior rhinomanometry in awake and seated position. Using posterior rhinomanometry, the transnasal pressure difference was measured between the nasopharynx and the external nares. The technique measures the difference in transnasal pressure that drives the flow of air through the nasal cavities.

Population: Per protocol population included all participants who fully complied with all study procedures and restrictions. Here, "N" signifies participants who were evaluable for this outcome measure.

The FOSQ was 30-item, validated psychometric instrument that assessed the impact of disorders of excessive sleepiness on functional outcomes relevant to daily behaviors and quality of life (QoL). The responses to the questionnaire were grouped according to five factors for analysis: 1) Activity Level, 2) Vigilance, 3) Intimacy and Sexual Relationships, 4) General Productivity and 5) Social Outcome. Participant used a scale of 0 to 4 to score each question of FOSQ which then grouped in above factors (where 0= I don't do this activity for other reasons, 1= Yes, extreme difficulty, 2= Yes, moderate difficulty, 3= Yes, a little difficulty, and 4= No difficulty). Total score of composite FOSQ was the sum of scores obtained on all 30 questions of the questionnaire. The possible range for the total score of composite FOSQ was from 0-120. A higher total score of composite FOSQ indicates better QoL of the participant.

On Day 29, prior to sleep, participants were asked to rate their overall experience with the strip as compared to before they enrolled in the study: ease of breathing, staying asleep, falling back to sleep, waking up too early, number of awakenings, falling asleep, sleep quality, sleep depth, dry mouth upon awakening, morning headache, nocturia (waking up to urinate), feeling refreshed in the morning. Experience was rated on scale of -2 to 2 were: -2 = Much worse, -1 = Somewhat worse, 0 = No change, 1 = Somewhat improve, 2 = Much improved (higher score indicated improvement).

Timeframe: Day 29

Population: Per protocol population included all participants who fully complied with all study procedures and restrictions. Here, "N" signifies participants who were evaluable for this outcome measure.

Participants answered the following question How likely are you to doze off or fall asleep in the following situations, in contrast to feeling just tired? 1. Sitting and reading, 2. Watching TV, 3. Sitting, inactive in a public place (e.g. a theatre or a meeting), 4. As a passenger in a car for an hour without a break, 5. Lying down to rest in the afternoon when circumstances permit, 6. Sitting and talking to someone, 7. Sitting quietly after a lunch without alcohol, and 8. In a car, while stopped for a few minutes in the traffic. Use the following scale to choose the most appropriate number for each situation: 0 = would never doze, 1 = slight chance of dozing, 2 = moderate chance of dozing, and 3 = high chance of dozing. Total ESS was calculated as the sum of all the individual scores observed for the above mentioned situations. The possible range for total ESS was 0-24. A lower total ESS indicates better sleep.

Sleep efficiency \[SE, a polysomnography (PSG)\] was measured as the percentage of total time in bed spent in sleep. It was calculated as the sum of Stage N1, Stage N2, Stage N3, and REM sleep, divided by the total time in bed and multiplied by 100. SE gives an overall sense of how well the participant slept and was measured for all participants with strip on Day 1 (Visit 2) in baseline phase, Day 8 (Visit 3) and Day 29 (Visit 4) in active phase, and in participants with and without strip on Day 30 (Visit 5) and Day 31 (Visit 6) cumulatively, in nasal resistance phase.

Sleep onset latency (SOL, a PSG parameter) was measured as the duration from the time when lights were turned off (as the participants attempted to sleep) till the time participant fell asleep. Determination of sleep and awake state was based on Electroencephalography (EEG) and behavioral parameters change. SOL was measured for all participants with strip on Day 1 (Visit 2) in baseline phase, Day 8 (Visit 3) and Day 29 (Visit 4) in active phase, and in participants with and without strip on Day 30 (Visit 5) and Day 31 (Visit 6) cumulatively, in nasal resistance phase.

Non-Rapid eye movement (NREM) sleep stage consist of 3 progressively deeper stages of sleep: N1 (transition period from being awake to falling asleep), N2 (where breathing and heart rate began to slow) and N3 (slow wave sleep where body heals and repair itself). Sleep architecture (SA) was measured by the percentage of sleep time spent by the participants in each stage (time spent in each stage to total time spent in NREM, multiplied by 100). SA was measured for all participants with strip on Day 1 (Visit 2) in baseline phase, Day 8 (Visit 3) and Day 29 (Visit 4) in active phase, and in participants with and without strip on Day 30 (Visit 5) and Day 31 (Visit 6) cumulatively, in nasal resistance phase.

Arterial oxygen saturation (SAO2) is the fraction of \[oxygen\]-saturated hemoglobin relative to total hemoglobin (unsaturated + saturated) in the blood. SAO2 in NREM and REM sleep was measured overnight by pulse oximetry with a finger probe using a computerized system. Lowest SAO2 values observed during the NREM and REM sleep were recorded for this endpoint. Oximetry measurements were performed in all participants with strip on Day 1 (Visit 2) in baseline phase, Day 8 (Visit 3) and Day 29 (Visit 4) in active phase, and in participants with and without strip on Day 30 (Visit 5) and Day 31 (Visit 6) cumulatively, in nasal resistance phase.
