Trial summary

It has been shown that a common cause for snoring and throat obstruction (obstructive sleep apnoea (OSA)) is excessive loss of muscle tone in the throat when the investigators go to sleep. This results in the partial collapse of the throat (snoring) or complete collapse (OSA) during sleep. Read more about this study

About this study

Official title: The Efficacy of Intra-oral Neuromuscular Stimulation Training on Snoring in Individuals With Primary Snoring or Mild Sleep Apnoea - A Multi Centre Trial

It has been shown that a common cause for snoring and throat obstruction (obstructive sleep apnoea (OSA)) is excessive loss of muscle tone in the throat when the investigators go to sleep. This results in the partial collapse of the throat (snoring) or complete collapse (OSA) during sleep.

45% of the male population snore. Sleep apnoea affects 4 to 6% of the population and is associated with increased incidence of raised blood pressure, heart attacks and strokes. Although there are several lifestyle practices associated with snoring such as smoking, obesity and drinking, a significant proportion of people may snore despite not being associated with these.

A solution to this issue is to improve the muscle tone of the throat so that it doesn't collapse so easily. Several studies have shown that certain types of throat exercises can help reduce snoring. Further studies have also shown that using electrical stimulation to exercise the tongue muscles has the same effect.

From this, doctors in the United Kingdom (UK) have developed a new type of device, eXciteOSA, that allows a more accurate and comfortable way of delivering this energy to exercise the tongue muscles. The device works by stimulating the tongue muscles during the day so that the tongue is less likely to collapse during sleep. It is a form of "workout" for the tongue and like other physical exercise regimes, it needs to be repeated regularly for a few weeks to take effect.

The aim of this study is to see if the eXciteOSA device is as effective as the previous methods and if it can reduce snoring and improve sleep quality.

This will be achieved by participants using the eXciteOSA once daily for a six week period. A two night sleep study with watchPAT along with a polysomnography will be completed before and after the therapy to compare results. Questionnaires on sleep quality and quality of life will also be completed pre and post therapy.

Read the detailed description

Study Design: Phase IV prospective, multi-centre post-market surveillance study.

Each site will follow the pre-determined study protocol, collecting endpoint relevant data which will then be analysed according to the methods outlined in this statistical analysis plan (SAP).

In brief, participants will proceed through three phases of the trial. The pre-trial phase collects data on the pre therapy state of the participant, after which they will enter the therapy phase where they use the device once daily for the required period whilst continuing to record the required data. The participant will stop using the device at the end of this stage and have a follow up phase during which trial indices will continue to be recorded.

The eXciteOSA transoral neurostimulation device is a home use device controlled by a mobile app. Its primary indication is for use in snoring in primary snorers or individuals with mild sleep apnoea.

It is reusable device that produces muscular stimulation via electrodes integrated into a mouthpiece used by the candidate. The product will be supplied be Signifier Medical Technologies ltd. The eXciteOSA device comes in a black box which contains the control unit, mouthpiece, universal serial bus (USB) cable and the instructions for use. Only the supplied products should be used together. Use of the product should be discontinued if it appears damaged in any way. The mouthpiece is connected to the control unit via a USB port and Bluetooth connection is established between the control unit and the app.

The device is to be used whilst awake, once daily for 20 minutes. The app automatically times the session and terminates it once completed. The therapy consists of a series of pulse bursts with the basic characteristic of 6 secs burst and 4 seconds rest. During the 20 mins therapy period the pulse frequency will change every 5 mins in a defined sequence. The intensity of the pulses can be controlled be the participant using the app, from a scale of 1 to 15. Patients should select the highest level they can tolerate without any discomfort.
