Detailed Study Protocol Parameters |
Study Objectives |
This study is a prospective, multi-center, two-arm study of subjects with an Apnea-Hypopnea Index (AHI) > 65 and <= 100 events/hr and/or Body Mass Index (BMI) >32 and <= 40 kg/m2, who are undergoing implant of the Inspire Upper Airway Stimulation (UAS) System for the treatment of obstructive sleep apnea (OSA). Subjects will be followed for 5 years post-implant
|
Study Population |
Subjects will be recruited in accordance with the approved indication for use and will only include those subjects who are within the new AHI (65 < AHI <=100 events/hr) and BMI (32 < BMI<=40 kg/m2) ranges. Subjects will be considered enrolled at the time of informed consent. Implanted subjects must meet the study eligibility criteria and will be followed for 5 years post-implant. Those subjects that are enrolled but fail to meet the eligibility criteria will be considered screen failures.
Study arms: AHI Cohort: Includes subjects with 65 < AHI<=100 events/hr BMI Cohort: Includes subjects with 32 < BMI<=40 kg/m2

Sample Size |
Number of subjects: 70 implanted subjects - 35 implanted subjects in each arm Assumptions for sample size estimation: NA Number of sites: 5 Sites location: US

Key Study Endpoints |
Safety Endpoints Primary: Evaluation of device and/or procedure related adverse events over time: relevant adverse events will be collected and reported through 5 years post-implant Secondary: NA
Effectiveness Endpoints Primary: • Evaluation of improvement in Apnea Hypopnea Index (AHI) over time: baseline (pre-implant) AHI compared to AHI after implant (collected and reported at annual study visits) • Evaluation of improvement in Oxygen Desaturation Index (ODI) over time: baseline (pre-implant) ODI compared to ODI after implant (collected and reported at annual study visits) • Evaluation of improvement in T90 (defined as total sleep time spent with arterial oxygen saturation (SaO2) < 90%) over time: baseline (pre-implant) T90 compared to T90 after implant (collected and reported at annual study visits) • Evaluation of improvement of Epworth Sleepiness Scale (ESS) over time: baseline (pre-implant) ESS compared to ESS after implant (collected and reported at annual study visits)
Subjects enrolled in the BMI cohort will have their BMI monitored yearly throughout the study Secondary: NA
