Stimulation Therapy for Apnea Reduction (Www.theSTARtrial.Com)
Effects of the Inspire Implantable Nerve Stimulation System on Obstructive Sleep Apnea

The purpose of this clinical trial is to demonstrate long-term safety and efficacy of the Inspire system. The Inspire Upper Airway Stimulation (UAS) therapy is intended to treat moderate-to-severe obstructive sleep apnea by improving airway patency through stimulation of the hypoglossal nerve. Study objectives include demonstrating that the Inspire system improves key indices of sleep apnea in a pre-specified percentage of patients.

OSA is characterized by recurrent episodes of airflow obstruction in the upper airway that results in oxygen desaturations and arousals from sleep. The most common symptom of OSA is excessive daytime sleepiness. Recent studies have also shown clear association of OSA with the development of obesity, hypertension, diabetes mellitus, and congestive heart failure.

Of those who are treated with CPAP, less than half remain effectively treated due to poor compliance, ineffective patient selection or inadequate therapeutic effect. Surgical procedures of the upper airway such as uvulopalatopharyngoplasty (UPPP) or tongue-based procedures have also met with equivocal results. The upper airway stimulation (UAS) therapy being evaluated in this trial may be a better alternative for treating airway obstructions involving the base of the tongue.

All enrolled subjects will participate in pre-implant testing to verify eligibility for implant. Following pre-implant testing, qualified subjects will undergo a surgical procedure to implant the Inspire system. Following implant, subjects will have scheduled follow-up visits, with data through 12 months serving as the primary endpoint.

Phase 3
Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Single Blind (Outcomes Assessor)
Primary Purpose: Treatment
Obstructive Sleep Apnea
Device: Inspire Upper Airway Stimulator
The stimulator is surgically positioned subcutaneously near the clavicle in the upper chest, and connects to a stimulation lead (around a hypoglossal nerve) and a sensing lead (in the chest). The stimulation contracts a patient's upper airway muscles to maintain airway patency, with the intent to keep the airway open during inspiration.
