Treating Obstructive Sleep Apnea using Targeted Hypoglossal Nerve Stimulation - The OSPREY Study (LNS005)
Multi-center, open-label, prospective, randomized trial of the aura6000 system in adults patients with moderate to severe obstructive sleep apnea who have failed other treatments. Primary objective includes demonstrating safety and effectiveness of the aura6000 system after 6 months of stimulation when compared to a control group with no stimulation.
The study involves up to 18 visits over a 16-month period. The study is broken into 4 parts: 1. Screening: Participants visit the research center to review health history and answer questions. During this time, a few sleep studies are done to make sure this is the right option. 2. Implant: During a same-day outpatient procedure, the aura6000® device is implanted beneath the skin. 3. Group Assignment: Participants are randomly assigned into one of two groups. Group 1 will have the device turned on after 1 month, whereas Group 2 will have the device turned on after 7 months 4. Follow Up: Participants visit the research center and sleep lab regularly for overnight sleep tests. These visits allow the study team to program the device and see if the implant is helping. There are also questionnaires that participants fill out to measure sleep quality.
Willing and capable of using the remote control and charger to activate the therapy and charge the implant, complete all questionnaires, return for all follow-up evaluations and sleep studies for the duration of the study.
