About this study

Official title: Trans Nasal Insufflation for the Treatment of Snoring and Obstructive Sleep Apnea

This research is being done to examine if a nasal cannula can be used to keep the throat open during sleep, thereby treating sleep apnea.

People with sleep apnea and people who snore without sleep apnea may take part in this study. Sleep apnea is a disorder caused by pauses in breathing due to repetitive closure of the throat. The most common form of treatment for sleep apnea is continuous positive airway pressure (CPAP) therapy. While CPAP therapy remains the simplest and most effective treatment for snoring and sleep apnea, patients have to wear a nasal mask throughout the night. For this reason, patients often have difficulty sticking to therapy.

Participants enrolled in this study will spend 3-nights in a sleep laboratory. In all nights, the investigators will monitor your sleep and your breathing throughout the night. The investigators will apply several electrodes (sensors) to your scalp and face to monitor your sleep and breathing, and other sensors to your chest, abdomen, cheek, and a finger to monitor your breathing and oxygen level.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Trans Nasal Insufflation (TNI) [nasal canula]Device

    Trans Nasal Insufflation, or TNI, uses air at flow rates delivered through a small nasal canula to reduce the severity and frequency of sleep apnea events.

    By using TNI we hope to increase the amount of air that the patient can breathe during periods of obstructive sleep disordered breathing.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in inspiratory airflow

    Measured: 2 nights

Secondary outcomes (2)
  1. Change in sleep apnea severity (AHI)

    Measured: 2 nights

  2. Change in Ratio of apnea-to-hypopnea events

    Measured: 2-nights

Questions about this trial

What is this clinical trial studying?

An observational study of Obstructive Sleep Apnea, run by Johns Hopkins University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 May 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in inspiratory airflow (time frame: 2 nights). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00832026, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 May 2023.
