研究概览
简要总结
This is a prospective, interventional, study in which patients with a history of habitual snoring to determine whether low pressure nasal continuous airway pressure can reduce the frequency, duration or intensity of snoring in subjects with mild to moderate snoring who do not have Obstructive Sleep Apnea (OSA).
详细描述
In this a prospective, interventional, study, each patient will be studied four times. Subjects without OSA will undergo an initial observational control study to establish the presence of snoring (session 1); a single CPAP titration night to determine the minimally effective CPAP level (session 2) to alleviate snoring; a subsequent full night of CPAP treatment at this CPAP level (CPAP not to exceed 6 cm H2O) using the Cloud9™ low-pressure CPAP device (session 3); and a final control night of study conducted off CPAP to assess whether the patient's snoring remained stable over time (session 4). In this study, each subject shall serve as his/her own control.

入选标准
- •Subject is > 18 years of age.
- •Subject is willing and able to provide written Informed Consent using a Patient Information and Consent form that has been reviewed and approved by a governing Institutional Review Board (IRB).
- •Subject has a history of habitual snoring (almost every night or every night for at least 30% of the night) as determined by the subject or a bed-partner.
- •Subject has been pre-screened and demonstrates no excess daytime sleepiness on an Epworth Questionnaire (an assessment of daytime sleepiness; high number = greater sleepiness) score of less than 11, no history of witnessed apneas or nocturnal gasping/choking episodes and a body mass index (BMI) ≤
- •Inclusion Criteria for treatment trials (Nights 2 and 3):
- •Subject meets Inclusion Criteria for the Baseline Trial (criteria a-d above)
- •The subject has snoring intensity that exceeds 40 dBA during ≥30% of the respiratory efforts during sleep time on the baseline study night.
排除标准
- •Subject has been diagnosed with COPD (Chronic Obstructive Pulmonary Disease), such as asthma, emphysema or chronic bronchitis.
- •Subject has a history of heart disease, heart attack or stroke.
- •Subject has uncontrolled or poorly controlled hypertension.
- •Subject has been diagnosed with Obstructive Sleep Apnea (OSA), defined as an apnea hypopnea index (AHI) ≥ 5/hr in the presence of excessive sleepiness (an Epworth score ≥ 11) or AHI ≥15/hr when there is no evidence of excessive daytime sleepiness (an Epworth score ≤ 10).
- •Subject is currently participating in another clinical study for which follow-up is ongoing.
结局指标
主要结局
Efficacy - The Cloud9™ device is expected to reduce the incidence of snoring.
时间窗: single night of sleep
The primary objective of this study is to demonstrate that minimally effective nasal CPAP (≤ 6 cm H2O) delivered by the Cloud9™ device reduces the number of snoring events and reduces snoring intensity in habitual, simple snorers in treatment session 3. We will test the hypothesis that the Cloud9™ device will decrease the number of loud snores by 50% or decrease the overall number of snores by 50%.
次要结局
- Safety - Adverse events associated with CPAP (nasal or skin irritation, epistaxis and sleep disruption) will occur in few subjects.(two different single nights)
