About this study

Official title: PAP to PAP: CPAP vs ASV for Insomnia Randomized Controlled Trial

The study will determine which of two different types of positive airway pressure (PAP therapy) modes are more effective in reducing sleep breathing events in chronic insomnia patients and in decreasing insomnia severity.

Read the detailed description

Patients presenting to the sleep clinic with a primary complaint of insomnia will be potential participants for this study. Following diagnostic polysomnography (PSG) testing, insomnia patients diagnosed with SDB and meeting inclusion criteria will be randomized to a PAP treatment arm, CPAP or ASV. Participants will complete titration studies with their assigned PAP mode and attend clinical follow-up appointments over a 14-16 week timeframe. Titration PSG studies will assess PAP pressure needs to ensure that patients are receiving optimal therapy at all times during this study. PAP adaptation barriers will be addressed as they arise during the study, because it is important that participants are able to use PAP therapy nightly during participation in this protocol. Baseline scores on insomnia severity, sleep quality, subjective insomnia parameters, sleep related impairment, and quality of life will be compared to outcome measures at the 4 month mark. Pre-treatment and post-treatment objective improvements on sleep studies will also be compared including sleep breathing indices, sleep consolidation indices, and objective data download information.

What participants receive

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

  • AirCurve 10 ASVDevice

    Also called VPAP Adapt, AutoSet CS2

    Device is able to provide both ASV therapy and CPAP therapy modes.

Study groups in NCT02365064
Study groupRoleWhat they receive
Continuous Positive Airway PressureActive comparatorContinuous positive airway pressure (CPAP) intervention as active comparator. Provides a fixed pressure for both inspiration and expiration.
Receives: Device: AirCurve 10 ASV
Adaptive Servo-VentilationExperimentalAdaptive servo-ventilation (ASV) positive airway pressure as experimental intervention. Provides a higher pressure for inspiration and a lower pressure for expiration with changes in the pressure support level to meet a target minute ventilation.
Receives: Device: AirCurve 10 ASV

What is being measured

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

  1. Insomnia Severity Index

    Change in insomnia severity from baseline to 4 months as measured by subjective questionnaire. The Insomnia Severity Index has seven questions. The seven answers are added up for a total score. Scores range from 0 - 28. A higher score indicates a more severe degree of insomnia.

    Measured: Baseline and 4 months

Secondary outcomes (5)
  1. Sleep Quality Rating

    8 point Likert scale for change in subjective sleep quality from baseline to 4 months. Lower scores indicated more positive sleep quality. A score 0 indicates excellent sleep quality, and a score of 7 indicates very poor sleep quality

    Measured: Baseline and 4 months

  2. Global Morning Rating

    Change in subjective rating from baseline to 4 months based on a 0-100% scale. Lower scores equal a more positive experience

    Measured: 4 months

  3. Sleep Onset Latency

    Change in from baseline to 4 months in sleep onset time (minutes)

    Measured: 4 months

  4. Wake After Sleep Onset (WASO)

    Change from baseline to 4 months for WASO in minutes

    Measured: 4 months

  5. Sleep Efficiency

    Change from baseline to 4 months in sleep efficiency (total sleep time/time in bed)

    Measured: 4 months

Questions about this trial

What is this clinical trial studying?

A study testing AirCurve 10 ASV in people with Insomnia and Sleep-Disordered Breathing, run by ResMed 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 6 inclusion and 11 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 9 Sep 2021. 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?

Yes. Results are posted in the registry (first posted 9 Sep 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Insomnia Severity Index (time frame: Baseline and 4 months). 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 NCT02365064, 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 9 Sep 2021.
