About this study

Official title: Evaluation of Treatment Efficacy and Comfort of a Modified Positive Airway Pressure Device to Treat Obstructive Sleep Apnea, in Comparison to a Market Released Device.

This study will test the hypothesis that the modified positive airway pressure (PAP) device for OSA will be no worse than a market released product in terms of its treatment efficacy, comfort and patient compliance. Patients will have their treatment pressure titrated using polysomnography (PSG) in the sleep laboratory, and then in a random order will spend additional time undergoing PSG using both devices, and using both devices at home for 3 weeks. Data will be collected from the PSG studies, device downloads, independent pressure-flow loggers, and custom questionnaires.

Read the detailed description

The study will be held in two parts. The main portion of the study which compares the modified PAP device and the market released product including the laboratory testing and home testing of the devices will be called 'Part A'. Additional nights using the PAP device with PSG monitoring will be used to gather additional observational flow data to allow distortion testing and investigation of the FPH (Fisher \& Paykel Healthcare) SensAwake (an unique feature which automatically lowers the pressure when a patient wakes up) algorithm while using PAP, this is part B.

Part A After the patient has undergone informed consent, their demographic and clinical variables will be collected and entered into a case report form (CRF) before any setup procedure is started. The patient will be asked to complete questionnaires regarding their normal therapy (ESS (Epworth Sleepiness Score), FOSQ (Functional Outcomes of Sleep Questionnaire), custom therapy comfort questionnaire), and then will be set up for a standard PSG. The patient will use their prescribed mask and a clean water chamber and breathing tube which will be connected to the modified PAP device. The patients will sleep on the device throughout the night while having their PAP titrated by a qualified sleep technician. Pressure titration is necessary for two reasons: firstly, it may have been a period of time since the participants last titration, and secondly this version of PAP involves the use of different levels of pressure. Pressures will be titrated according to the AASM (American Academy of Sleep Medicine) Clinical Guidelines for the Manual Titration of Positive Airway Pressure in Patients with OSA.

The participant will be randomized to either the modified PAP or market released device group. They will be issued with a PAP device and a pressure-flow logger to be used at home in the usual manner of their PAP therapy for 3 weeks (+/- 4 days), after which participants will return to the FPH sleep laboratory to participate in a overnight PSG study using their first device. At this visit the participant will also swap to the second PAP device; and the above home use repeated on device 2.

Part B After informed consent form the patient will be set up for a standard PSG, and sleep overnight using the modified PAP device, their prescribed mask, and a clean water chamber and breathing tube. This testing will be performed to provide additional flow data to the development engineers. This includes, but is not limited to, distortion testing and adjustment of device parameters during the sleep study. Distortion testing analyses the impact of the PAP pressure changes on the participants breathing or airflow.

What is being measured

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

  1. PAP Treatment Efficacy

    The participants apnea hypopnea index (AHI) will be assessed using the PSG data, device download data and the independent pressure-flow logger. The apnea-hypopnea index is the total number of sleep disordered breathing events divided by total sleep time.

    Measured: After 1 night in the sleep lab and 3 weeks use of the device in the home.

Secondary outcomes (2)
  1. PAP Treatment Comfort

    Participants will be administered comfort questionnaires regarding the comfort of all devices. The range of responses is 1 to 5 with 1 being very uncomfortable to 5 being very comfortable.

    Measured: After 1 night in the sleep lab and 3 weeks use of the device in the home.

  2. PAP Compliance

    Participants therapy utilisation will be compared between the two devices using the device data download, and the independent pressure-flow logger.

    Measured: After 1 night in the sleep lab and 3 weeks use of the device in the home.

Questions about this trial

What is this clinical trial studying?

A study testing PAP device in people with Obstructive Sleep Apnea (OSA), run by Fisher and Paykel Healthcare at 1 site in New Zealand.

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 9 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 24 Apr 2017. 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 New Zealand. 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 24 Apr 2017). 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?

PAP Treatment Efficacy (time frame: After 1 night in the sleep lab and 3 weeks use of the device in the home.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 24 Apr 2017.
