Randomized Study of Provent Versus Sham Device to Treat Obstructive Sleep Apnea

Phase 4

Completed

• Conditions: Obstructive Sleep Apnea Hypopnea; OSA; OSAH
• Interventions: Device: Provent Professional Sleep Apnea Therapy Device; Device: Sham Device

• Registration Number: NCT00772044
• Lead Sponsor: Ventus Medical, Inc.

Brief Summary

Primary Endpoints:

•Comparison of difference in AHI at one-week in-lab polysomnography between "device on" and "device off" nights, controlling for sleep position (supine vs. non-supine)

Secondary Endpoints: By polysomnography, reduction in:

* AHI with device on vs. off at 3 months, controlling for sleep position

* Oxygen desaturation index with device on vs. off

* Arousal index with device on vs. off

* Duration of snoring with device on vs. off

* Epworth Sleepiness Scale

Patient acceptance, in terms of:

* Refusal rate at screening

* Discontinuation rate during follow-up

* Daily compliance rate

* Device-related adverse events

* Serious adverse events
