A Disposable Device NAS to Treat Obstructive Sleep Apnea and Snoring

December 18, 2018 updated by: Clete A. Kushida, Stanford University
The purpose of this research study is to test a new approach for treating patients with obstructive sleep apnea and/or snoring. The new nasal device, nastent (NAS: nasal airway stent), appears to be a useful alternative or additive treatment.

Detailed Description

The nasal stent basically helps to splint the soft palate open. Subjects have a baseline (diagnostic) sleep study without wearing the device. Subjects are then fitted with the device and then subjects wear the device for at least 7 nights during their sleep while at home. Subjects then return for a repeat in-laboratory sleep study while wearing the device. The primary outcome is to assess the effectiveness of the device by change in the apnea-hypopnea index (number of sleep-related abnormal breathing events per hour of sleep) while wearing the device compared to baseline.

  • Allocation: NA
  • Interventional Model: SINGLE_GROUP
  • Masking: NONE

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
EXPERIMENTAL: Nastent
A baseline sleep study is obtained from the subject, without wearing the device. The individual wears the device at home for at least 7 nights, and then returns to the sleep lab for an in-laboratory sleep study while wearing the device.
Device: Nastent
Use of the device while at home and in the sleep lab

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Apnea-Hypopnea Index (AHI)
Time Frame: In-lab sleep study obtained at least 7 nights following use of the device at home
Abnormal breathing events (apneas = complete pauses in oronasal airflow; hypopneas = decreases in oronasal airflow) per hour of sleep. This is measured through polysomnography (sleep study) by a nasal thermistor and oral pressure sensor.
In-lab sleep study obtained at least 7 nights following use of the device at home
