Targeted Hypoglossal Neurostimulation Study #3

Not Applicable
Completed
Conditions
Obstructive Sleep Apnea
Interventions
Device: aura6000 System
Registration Number
NCT02263859
Lead Sponsor
ImThera Medical, Inc.
Brief Summary

The purpose of this study is to evaluate the benefits and risks of hypoglossal nerve stimulation with the ImThera Medical aura6000 System as a potential therapeutic option for individuals with moderate to severe OSA that have failed or do not tolerate PAP.

Detailed Description

The objectives of this study are to evaluate the safety and effectiveness of the aura6000 System for the treatment of moderate to severe obstructive sleep apnea (OSA) in individuals who have failed or do not tolerate positive airway pressure (PAP) therapy or have failed or are intolerant of or refuse indicated alternative OSA treatments (such as oral appliances, positional devices and conventional sleep surgeries). PAP failure is defined as an inability to eliminate OSA (AHI \> 20 despite PAP usage) and PAP intolerance is defined as: 1) inability to use PAP (greater than 5 nights per week of usage; usage defined as greater than 4 hours of use per night); or 2) unwillingness to use PAP (for example, a patient returns the PAP system after attempting to use it). The results of this study are anticipated to provide reasonable assurance of the safety and effectiveness of the aura6000 System when used as intended and to support the application for FDA Premarket Approval of the system.

GroupInterventionDescription
Treatmentaura6000 SystemThe Treatment Group will be implanted with the aura6000 System and have therapy turned ON at the Month 1 follow-up visit.
Controlaura6000 SystemThe Control Group will be implanted with the aura6000 System and receive treatment as-usual, (i.e. any non-PAP, non-surgical OSA treatment including oral appliances and positional devices being used prior to enrollment in the study) until 14 days (washout period) prior to the Month 4 visit. At the Month 4 + 1 day follow-up visit, subjects in the Control Group will have therapy turned ON for the duration of the study.
Primary Outcome Measures
NameTimeMethod
Improvement in Oxygen Desaturation Index (ODI)Baseline to 4 months post-implant

Proportion of subjects who experience improvement in the oxygen desaturation index 4% (ODI 4%) at the Month 4 visit as defined above in the ODI Responder definition.

It is hypothesized that the observed responder rate in the Treatment Group will be significantly greater than the responder rate in the Control Group at 4 months post-implant.

Improvement in Apnea Hypopnea Index (AHI)Baseline to 4 months post-implant

Proportion of subjects who experience improvement in the apnea-hypopnea index (AHI) at the Month 4 visit as defined above in the AHI Responder definition.

It is hypothesized that the observed responder rate in the Treatment Group will be significantly greater than the responder rate in the Control Group at 4 months post-implant.

Safety AnalysisBaseline to 12 months post-implant

Estimate the incidence of serious adverse events (SAEs) related to the aura6000 device or procedure, including any unanticipated adverse device effects.

Secondary Outcome Measures
NameTimeMethod
Change in Epworth Sleepiness Scale (ESS)Baseline to 4 months post-implant
Change in Functional Outcomes of Sleep (FOSQ)Baseline to 4 months post-implant
Change in EuroQol 5 Dimensional (EQ-5D)Baseline to 4 months post-implant
Long-term Responder RateBaseline to 12 months post-implant
