Obstructive Sleep Apnea Non-PAP Outcomes and Viable Alternatives (OSANOVA): Comparison of Mandibular Advancement Device and Hypoglossal Nerve Stimulation Outcomes

Washington University School of Medicine·interventional·Posted Jul 20, 2025·Updated Apr 14, 2026

In Brief

A clinical study evaluating MAD and HGNS for Obstructive Sleep Apnea. Currently recruiting, targeting 60 participants across 1 site.

Detailed Summary

OSANOVA is a non-randomized clinical trial which aims to compare outcomes of mandibular advancement device (MAD) and hypoglossal nerve stimulation (HGNS) therapies in moderate-to-severe OSA patients who fail, decline, or are intolerant to positive airway pressure (PAP) therapy (referred to as PAP-failing patients). The primary aim of the study is to compare the outcomes between PAP-failing moderate-to-severe OSA patients receiving MAD and those receiving HGNS therapy. Primary Outcome measures include changes in Pittsburgh Sleep Quality Index (PSQI) scores. Secondary aims will help us describe the outcomes between PAP-failing moderate-to-severe OSA patients receiving MAD and those receiving HGNS therapy. Secondary outcome measures include: * adverse events, * Epworth Sleepiness Scale (ESS), * Symptoms of Nocturnal Obstruction and Related Events (SNORE-25), * patient-reported satisfaction, * CGI-Improvement, * the rate of subjects re-selecting the treatment, and * the rate of subjects recommending the treatment. and * changes in sleep study metrics (i.e., AHI, ODI, mean arterial saturation, and Time\<90%),

Interventions

MADdevice

MAD intervention involves the use of a mandibular advancement device, which is designed to reposition the lower jaw and tongue to keep the airway open during sleep.

HGNSdevice

HGNS intervention involves a surgical procedure to implant a device that stimulates the hypoglossal nerve to prevent airway collapse during sleep.
