Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Devices - Prototype nasal dilator strip

Experimental: All participants (Baseline phase) - All the participants were applied nasal dilator strip during the sleep laboratory night on Day 1.

Experimental: All Participants (Active Phase) - All the participants wore nasal dilator strip over a 1 month in-home use period and returned for sleep laboratory nights after 7 (Day 8) and 28 days (Day 29) of treatment

Experimental: All Participants (Nasal Resistance Phase) - The participants were randomized to receive a sequence of either 'strip'/' no strip' or 'no strip'/'strip' on 2 sleep laboratory nights (on Day 30 and Day 31) based on the randomization schedule


Treatment: Devices: Prototype nasal dilator strip
External Prototype Nasal Dilator strip. GSK prototype nasal dilator AB 2R11. All the participants used nasal dilator strip throughout the active phase of the study (Day 1 to Day 28). Followed by that all the participants used the nasal strip on Day 29 or 30 in Nasal resistance phase of the study as per their randomization sequence.

Use of over the counter sleep promoting agents including diphenhydramine, doxylamine, tryptophan, valerian root, kava kava, melatonin, St John's Wort and Alluna. Use of over the counter alertness aids including caffeine and guarana.
* Subject currently uses any topical nasal decongestants (nasal sprays, drops, etc). Subject must have discontinued use of topical decongestants at least 7 days prior Baseline.
* Subject is experiencing an acute upper respiratory tract infection at during qualification phase and at Baseline visit.
* Subject abuses alcohol (regularly drinks more than 3 drinks per day) or has a recent history (within last 2 years) of substance or alcohol abuse. Regular consumption of xanthine-containing beverages (i.e. tea, coffee, or cola) comprising usually more than 5 cups or glasses per day.
* Subject has a positive drug of abuse screening result.
* Subject has severe, unstable disease states (e.g. myocardial infarction, congestive heart failure, diabetes, cirrhosis, cancer, epilepsy, or stroke), pain syndromes, (e.g. fibromyalgia) or any medical or surgical condition that places the subject at unacceptable risk if he/she were to participate in the study or confounds the ability to interpret data from the study or who in the judgement of the principal investigator would not be suitable for entry into this study.
* Severe nasal obstruction caused by structural abnormality that renders the subject unsuitable for the study in the opinion of the investigator, i.e. nasal polyps, severe deviated septum.
* Subject is unwilling to be videotaped or recorded during the PSG studies.
* Current Treatment for Sleep Disordered Breathing a) Subject currently uses devices prescribed for sleep disordered breathing including Continuous Positive Airway Pressure (CPAP), mandibular advancement devices, tongue displacement devices. b)Over-the-counter products such as chin straps, pillows, internal/external nasal dilators are acceptable provided usage is discontinued at least 28 days prior to Baseline.
