Study of Provent Treatment of Obstructive Sleep Apnea in Patients Who Are Non-compliant With CPAP

NCT00901771 | Completed

• 1 other identifier: Ventus C020
• Study Type: interventional
• Target: 50
• Locations: 1 country
• Sites: 1

Brief Summary

The primary objective of the proposed investigation is to evaluate the efficacy of the Provent device in a sample of OSA patients who have either refused or been non-adherent with PAP treatment. Both initial efficacy (evaluated after approximately one week with Provent) and efficacy after approximately 5 weeks in patients who demonstrate initial efficacy will be assessed. A secondary objective is to assess adherence with Provent treatment during the 5-week evaluation period.

Interventions

Provent DEVICE

This is a non-randomized, single-arm, case series study. All subjects will receive Provent device.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Current signs and symptoms consistent with a diagnosis of OSA in the opinion of the study physician
• Rejection of PAP treatment or minimally adherent with PAP treatment
• Use of the Provent device for a specified amount of time each night during three consecutive nights of the trial period
• AHI \> 15, or AHI \> 10 with evidence of CMS-recognized symptoms or co- morbidities, on screening/baseline PSG
• Investigator believes that subject can benefit from OSA treatment
• Subject understands and is willing and able to comply with study requirements

You may not qualify if:

• Use of any device that interferes with nasal or oral breathing
• Persistent blockage of one or both nostrils which prevents airflow in one or both nostrils
• Any chronic sores or lesions on the inside or outside of the nose
• Chronic use of nasal decongestants other than nasal steroids
• History of allergic reaction to acrylic-based adhesives (such as those found in BAND-AIDS®)
• Current acute upper respiratory (including nasal, sinus, or middle ear) inflammation or infection or perforation of the tympanic membrane (may be re-considered for participation after the acute episode resolves)
• History of frequent and/or poorly treated severe nasal allergies or sinusitis which may interfere with the ability to use Provent
• Severe respiratory disorders (including respiratory muscle weakness, bullous lung disease, bypassed upper airway, pneumothorax, pneumomediastinum, etc.).
• Pathologically low blood pressure.
• Narcolepsy, idiopathic hypersomnolence, chronic insomnia, restless legs syndrome, REM sleep behavior disorder or any other diagnosed or suspected sleep disorder other than OSA that could affect the likelihood of apneas/hypopneas during a PSG.
• Periodic limb movement arousal index (PLMAI) \> 10 on the screening/baseline PSG.
• Current use of diurnal or nocturnal supplemental oxygen
• Currently working night or rotating shifts
• Consumption of \> 10 caffeinated beverages per day (approximately 1000 mg per day)
• History of severe cardiovascular disease, including New York Heart Association Class III or IV heart failure, coronary artery disease with angina or myocardial infarction in the past 6 months, stroke in the past 6 months
