Summary

This trial tests a device called the LinguaFlex™ Tongue Retractor, which is placed in the tongue to help keep the airway open during sleep. It targets adults with moderate to severe sleep apnea. By preventing the tongue from blocking the airway, it aims to reduce snoring and sleep apnea episodes.

Who is the study for?
Adults over 18 with moderate to severe Obstructive Sleep Apnea (OSA) who have an AHI score of 15-50 and haven't found success with PAP therapy can join. They must not use other OSA treatments during the study, be able to consent, and not be pregnant or have certain medical conditions like heart failure or bleeding disorders.
What is being tested?
The trial is testing the LinguaFlex Tongue Retractor (LTR), a device inserted into the tongue to prevent it from blocking the airway during sleep. The goal is to see if it reduces symptoms of OSA and snoring over one year.
What are the potential side effects?
Potential side effects are not explicitly listed in this summary but may include discomfort or pain at the site of insertion, possible infection risk, and any reactions related to allergies against materials used in LTR such as Silicone, PEEK, Polyurethane.

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
Common treatments for Obstructive Sleep Apnea (OSA) work by maintaining an open airway during sleep. CPAP machines provide continuous positive air pressure to keep the airway from collapsing. Oral appliances, like mandibular advancement devices, reposition the jaw or tongue to prevent airway obstruction. The LinguaFlex™ Tongue Retractor, an investigational device, specifically prevents the tongue from moving backward, which helps keep the airway open. These treatments are vital for OSA patients as they reduce apneas, improve sleep quality, and mitigate the risk of complications such as cardiovascular issues and daytime sleepiness.
