Brief Summary

The purpose of this post-market study is to assess safety and effectiveness of Inspire Upper Airway System (UAS) in a commercial setting. This study will provide additional clinical evidence of Inspire UAS for treatment of moderate to severe obstructive sleep apnea (OSA) using a randomized controlled trial design.

Detailed Description

This study is a prospective, multi-center, randomized controlled study with a delayed start arm, conducted under a common implant protocol.

Up to 40 study subjects will be implanted at up to six centers in Europe. Subjects will be evaluated at baseline, implant, post-op (randomized) and 1-, 2-, 3,- 4- and 6-months post-implant.

Baseline data will include collection of demographics and medical history, completion of a physical exam, Functional Tongue Exam (FTE), and subject quality of life (QoL) questionnaires (Functional Outcomes of Sleep Questionnaire (FOSQ) and Epworth Sleepiness Scale (ESS)). Adverse event data will be collected from the time of baseline testing through the 6-month study follow-up.

Implant eligibility assessments will include home sleep testing (HST), a surgical consultation and a drug induced sedated endoscopy (DISE) to determine if the subject is a qualified candidate for implant.

Subjects meeting all baseline and pre-screening requirements will be implanted with the Inspire system. Intra- and post- operative procedure data will be collected. Subjects will be seen for a post-operative check one week after implant. During this visit, subjects will be randomized 1:1 to the ACTIVE group or the DELAY group. However, the Inspire system will not be activated (turned "on") during the first month post-implant to allow for post-surgical healing.

Only subjects randomized to the ACTIVE group will return for the 1-month follow-up visit at which time the device will be activated (turned "on"). The subjects will be provided with a patient remote and instructed on its use. These ACTIVE arm subjects will be instructed to use their Inspire system on a nightly basis and return for a 2-month visit for an in-laboratory sleep study to complete device titration.

All subjects (ACTIVE and DELAY) return for the 3-month visit to complete a HST (DELAY subjects' therapy will remain off during the HST). In addition, QoL and patient satisfaction surveys, Functional Tongue Exam (FTE), and general health assessments, including adverse event review, will be collected. Subjects in the DELAY arm will have their therapy activated at the end of the 3 month visit, and return for a 4-month visit for an in-laboratory sleep study to complete device titration. All subjects will return for a 6-month and final visit where a two-night HST will be completed. In addition, QoL and patient satisfaction surveys, physical exam and FTE data will be collected; a device check will be completed as well as adverse event review. Therapy usage and device adjustment data, as well as a subject satisfaction with therapy survey, will be collected for additional analysis. Safety data will be collected throughout the study.

Group Type: OTHER

Inspire® Upper Airway Stimulation (UAS) System

Intervention Type: DEVICE

This is a single-arm study; all participants will be implanted with the Inspire® Upper Airway Stimulation (UAS) System. This is a permanent, implantable therapy device, which consists of three implantable components: an implantable pulse generator (IPG), a stimulation lead, and a sensing lead. In addition, the patient receives a handheld remote to activate the therapy
