Summary

This study is a prospective, multi-center, single-arm, open-label study evaluating the safety and effectiveness of therapy with the ProSomnus EVO Sleep and Snore Device in individuals with severe obstructive sleep apnea.

Detailed description

This study is a prospective, multi-center, single-arm, open-label study evaluating the safety and effectiveness of therapy with the ProSomnus EVO Sleep and Snore Device in individuals with severe obstructive sleep apnea (OSA). Study participants will receive a custom ProSomnus EVO Sleep and Snore device and then be tested using a Type II home sleep apnea test (HSAT) to determine if they have achieved apnea-hypopnea index (AHI) \< 15 h-1 with the device in place. Home sleep apnea testing will be conducted at predetermined timepoints rather than based on subjective measures such as symptom alleviation. After completing a set device advancement and testing protocol, study participants will complete a final HSAT six months after therapy initiation. This value will be used to determine the therapeutic success rate of the appliance. Safety evaluations will be conducted at each study visit that takes place after therapy initiation. These evaluations, along with dental examinations and adverse event reports, will be used to determine if the safety endpoint is met. Participants will continue to be followed for an additional six months after collection of data for the primary endpoints.

Interventions

Type	Name	Description
DEVICE	ProSomnus® EVO Sleep and Snore Device	The ProSomnus® EVO Sleep and Snore Device is an intraoral device for snoring and obstructive sleep apnea. It works by repositioning the mandible during sleep, thereby improving the flow of air through the patient's pharyngeal space. The ProSomnus® EVO Sleep consists of maxillary and mandibular device arches that are CAD/CAM designed with twin-mated posts and digitally milled to be patient-specific according to physician prescription. Prescribed advancements can be achieved by simply removing the current upper or lower device arch and inserting the next upper or lower device arch in the mandibular advancement series. The device does not have any adjustment mechanisms to modify or maintain the mandibular position such as pistons, screws, straps, or repositioning elastics. The device is supplied nonsterile.
