Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate the effectiveness, feasibility, and safety of mandibular advancement devices (MAD) for treating severe obstructive sleep apnea (OSA) in patients who are CPAP intolerant and have failed hypoglossal nerve stimulation (HGNS).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

ROHMA is a pilot/single intervention study aiming to evaluate effectiveness of a mandibular advancement device (MAD) for treating moderate to severe obstructive sleep apnea (OSA) in patients who have failed hypoglossal nerve stimulation therapy (HGNS). Individuals who received a HGNS therapy at Washington University from April 4 2019 to October 20 2024, or were enrolled in a prior study (HRPO #: 202309014) will be recruited for the study.

Mandibular Advancement Device (MAD)

This study is experimental. It involves a single-intervention design where participants who have failed hypoglossal nerve stimulation (HGNS) therapy for moderate to severe obstructive sleep apnea (OSA) will be treated with a mandibular advancement device (MAD).

Group Type EXPERIMENTAL

Mandibular advancement device (MAD)

Intervention Type DEVICE

The intervention in this study involves fitting and using a mandibular advancement device (MAD), specifically the ProSomnus Sleep Device, to treat moderate to severe obstructive sleep apnea (OSA) in patients who are intolerant to CPAP and have failed hypoglossal nerve stimulation (HGNS) therapy.
