Is this trial a fit for you?

Likely a good fit

Adults with obstructive sleep apnea who completed the parent NPA-OSA study, were compliant with the device, and wish to continue using it are ideal candidates.

Probably not a fit

Patients who were non-compliant with the device during the parent study or who cannot tolerate a nasopharyngeal airway are unlikely to benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This long-term follow-up allows participants from the parent trial to continue using a nasopharyngeal airway device for obstructive sleep apnea while remaining under study-team oversight. The study team will maintain contact as needed and participants will receive clinical follow-up with their own physicians. At 12 months participants will complete sleep questionnaires to document symptoms, device tolerability, and ongoing use. Participants who were non-compliant in the parent study are excluded and continued device use is voluntary.

Why it matters

Potential benefit: If successful, continued device use could help maintain or improve sleep apnea symptoms and sleep quality without more invasive treatments.

How similar studies have gone: Short-term studies and the parent trial have shown some benefit with nasopharyngeal airway devices, but robust long-term evidence is limited.
