What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to gather more long-term data on the safety and effectiveness of Inspire therapy for people with obstructive sleep apnea (OSA). The treatment uses the Inspire® UAS System, a device implanted to keep the airway open during sleep. It targets individuals with moderate-to-severe OSA who have struggled with CPAP therapy due to discomfort or persistent symptoms. Participants should be prepared to have the device implanted and use a remote to control it. Those experiencing frequent issues with CPAP and OSA may find this trial suitable. As an unphased trial, this study offers a unique opportunity to contribute to understanding the long-term benefits of an innovative treatment for OSA.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial team or your doctor.

What prior data suggests that the Inspire® UAS System is safe for obstructive sleep apnea?

Research has shown that the Inspire® Upper Airway Stimulation (UAS) System is generally safe for adults with obstructive sleep apnea who cannot use traditional treatments like positive airway pressure (PAP). Studies have found that people with moderate-to-severe sleep apnea usually tolerate the device well.

Inspire therapy uses a small device to help keep the airway open during sleep. Testing has confirmed its safety in everyday situations. Most users do not experience serious side effects. Some may feel pain or discomfort around the device placement, but these issues are usually manageable.

Overall, the Inspire UAS System maintains a strong safety record, especially for those who have difficulty with other treatments. ^{1 2 3 4 5}

Why are researchers excited about this trial?

The Inspire® UAS System is unique because it offers a new approach to treating obstructive sleep apnea (OSA) by using an implantable device to stimulate the airway muscles. Unlike traditional options like CPAP machines, which require wearing a mask during sleep, this system works by sending mild electrical pulses to keep the airway open. Researchers are excited about this treatment because it can improve patient comfort and adherence, potentially providing a more effective and less invasive solution for those who struggle with existing therapies.

What evidence suggests that the Inspire® UAS System is effective for obstructive sleep apnea?

Research has shown that the Inspire® UAS System effectively reduces symptoms of obstructive sleep apnea (OSA). One study found it significantly decreased the number of breathing interruptions by about 20 times per hour in the short term and 16 times per hour in the long term. Another study reported that people with moderate to severe OSA felt less sleepy and experienced a better quality of life after using the device. Patients also highly prefer the Inspire system, with 91% choosing it over traditional CPAP machines. Overall, these findings suggest that Inspire therapy can greatly improve sleep and quality of life for people with OSA. ^{1 6 7 8 9}

Are You a Good Fit for This Trial?

This trial is for adults aged 22 or older with moderate-to-severe Obstructive Sleep Apnea (OSA) who haven't had success with CPAP therapy due to non-compliance, discomfort, or persistent symptoms. Participants must be willing to have a stimulation device implanted and use a remote to activate it, as well as complete follow-up visits and home sleep studies.

Inclusion Criteria

at will Desiring and able to have stimulation hardware implanted and use a patient remote to activate the stimulation as desired.

I have been diagnosed with moderate-to-severe sleep apnea.

I cannot use CPAP therapy effectively due to issues like discomfort or side effects.

Exclusion Criteria

You have a medical device that could be affected by the Inspire system.

My throat structure does not allow for a certain sleep apnea treatment.

I have a condition affecting my ability to control my upper airway.

Published Research Related to This Trial

Upper airway stimulation (UAS) using the Inspire II implant is an effective treatment for obstructive sleep apnea (OSA) by stimulating the hypoglossal nerve to prevent airway obstruction and improve airflow.

Clinical studies show that UAS significantly enhances sleep quality and respiratory metrics in patients with moderate-to-severe OSA, making it a viable long-term treatment option with low associated risks.

NCBI (Pubmed)

pubmed.ncbi.nlm.nih.gov

Upper Airway Stimulation Therapy. Green, KK., Woodson, BT.[2017]

Hypoglossal nerve stimulation (HNS) with Inspire is a cost-effective treatment for patients with moderate to severe obstructive sleep apnoea who cannot tolerate CPAP, showing an incremental cost-effectiveness ratio of £17,989 per quality-adjusted life-year (QALY) gained.

Patients receiving HNS are expected to gain more quality-adjusted life years (12.72 QALYs) compared to those receiving no treatment (11.15 QALYs), indicating that HNS not only improves health outcomes but is also a financially viable option for the NHS.
