First Patient Implanted in OSPREY OSA Neurostimulator Clinical Study


LivaNova PLC has announced the first patient implanted in the investigational device exemption (IDE) clinical study, “Treating Obstructive Sleep Apnea using Targeted Hypoglossal Neurostimulation” (OSPREY). The randomized controlled trial (RCT) seeks to demonstrate the safety and effectiveness of the LivaNova aura6000 System, an implantable hypoglossal neurostimulator intended to treat adult patients with moderate to severe obstructive sleep apnea (OSA). The first OSPREY patient was implanted by Dr. Mitchell Miller at BayCare’s Morton Plant Hospital in Clearwater, Florida.

“With this first patient and the launch of this randomized clinical trial, we are taking a major step toward finding new, effective treatments for the global population of OSA patients and adding to the clinical literature surrounding these therapies,” said Dr. Atul Malhotra, Professor of Medicine at the University of California, San Diego and Principal Investigator for OSPREY. Dr. Malhotra is an internationally recognized expert in sleep apnea who has published more than 385 original manuscripts, plus more than 285 reviews/chapters, in leading journals and actively treats patients in pulmonary, critical care and sleep medicine. “The clinical study will determine if the apnea-hypopnea index responder rate of subjects stimulated via the device is statistically significantly higher than the rate of subjects without stimulation. Throughout the study, independent statisticians will conduct interim data analyses to determine predictive probability of success for OSPREY. With this being a randomized study rather than simply observational, we will get a clear sense that targeted hypoglossal neurostimulation therapy is the mechanism of improvement for the patients.”

The OSPREY study will take place at approximately 20 sites across the United States. It will ultimately enroll a maximum of 150 adult patients with moderate to severe OSA who do not achieve results from a traditional continuous positive airway pressure (CPAP) machine or have declined its use.

“Approximately one billion people worldwide live with OSA, but most are undiagnosed and untreated1, which can seriously impact their health, increasing the rates of death, stroke, hypertension, motor vehicle accidents, heart failure, diabetes, depression and daytime sleepiness,”2 said Damien McDonald, LivaNova Chief Executive Officer. “There is a great need to offer patients diagnosed with OSA new and less restrictive treatment options. The OSPREY study will be the first RCT to confirm efficacy of hypoglossal nerve stimulation and now, with the first OSPREY patient implanted, we are another step closer to successfully bringing the innovative aura6000 System to market.”

The aura6000 System, which received CE mark in 2012, is designed to maintain muscle tone of the tongue and upper airway so that airway obstruction and resulting sleep apnea are significantly reduced or eliminated. It features a programmable, rechargeable and implantable pulse generator (IPG) that is implanted in a subcutaneous pocket near the patient’s clavicle during outpatient surgery. The IPG generates mild stimulation that is delivered via a lead to the hypoglossal nerve, thereby stimulating the patient’s tongue during sleep and keeping the airway open. An innovative alternative to the traditional CPAP machine, the aura6000 System allows the patient to sleep without being connected to masks, hoses, facemasks or mouthpieces.
