A Pivotal Subjective Sleep Study of a Nasal Dilator (Breathe Right Tan)

Completed · Phase 2 · Has a placebo group

Conditions studied: Congestion, Nasal

In brief

This randomized, double-blind, parallel group, placebo-controlled study assessed the effects of a novel nasal dilator strip in consumers with chronic nocturnal nasal congestion who have trouble with their sleep. Participants who met the entrance criteria were 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 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 where they self-administered the validated subjective questionnaire "the Nocturnal Rhinoconjunctivitis Quality of Life Questionnaire (NRQLQ)".

• Participant has a non-typical sleep schedule (e.g. shift-work).
• Participant plans travel involving time-zone changes during the study period.
• Regular/habitual consumption of more than five cups or glasses per day of xanthine-containing beverages (i.e. tea, coffee, cola).
• Participant currently uses any product or medication that has an effect on nasal congestion or sleep. Participant must have discontinued use of the following products according to the timings specified below:

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. Devices prescribed or used for sleep disordered breathing including Continuous Positive Airway Pressure (CPAP), mandibular advancement devices, tongue displacement devices iv. Use of any intranasally administered medications (e.g. Miacalcin) b) Within 3 days prior to the initiation of the baseline qualification phase: i. Oral decongestants ii. Short-acting prescription and non-prescription antihistamines, including ocular preparations and antihistamines contained in OTC sleep medications or 'night time' pain formulations (e.g. Benadryl, Chlortrimeton, Dimetane, Tavist) iii.

Intranasal corticosteroids g) Within 8 weeks prior to the initiation of the baseline qualification phase: i. Inhaled oral, intramuscular, intravenous, ocular and/or dermatological corticosteroid (with the exception of 1% or less topical hydrocortisone products) h) Within 3 months prior to the baseline qualification phase: i.
