This study is looking at the long-term use of a device called the nasopharyngeal airway obstructive sleep apnea (NPA-OSA) device. This device is a flexible, silicone tube that you insert into your nostril before sleep to help with snoring and obstructive sleep apnea (when breathing repeatedly stops and starts during sleep). The study wants to see how well the NPA-OSA device continues to reduce the severity of your sleep apnea over 24 months. You can join this study if you previously participated in the parent study (HUM00179497) and want to keep using the NPA-OSA device. The study is currently unclear on its recruitment status and plans to enroll 20 participants.

Study design

This is an interventional study, meaning you will receive a specific treatment. It is a long-term follow-up study for participants who completed a previous study.

What's involved

You will continue using the NPA-OSA device. The study team will stay in contact with you as needed, and you will have clinical follow-up with your doctor. At 12 months, you will complete sleep questionnaires.

Compensation

Not stated in the trial record.

Follow-up

The primary endpoint measures the change in sleep apnea severity at 24 months, indicating a follow-up period of at least two years.
