About this study

The purpose of this study is to evaluate the usability and suitability of the Drive app (app under test) to measure sleep parameters during CPAP use.

This is a prospective, non-randomized, single arm exploratory study without blinding.

Read more

Current users of CPAP therapy will be recruited for this study and will be provided with a smartphone (app under test installed) and a non-contact motion sensor in their home environment. These devices will measure sleep metrics such as sleep stages and breathing metrics that may be associated with sleep disordered breathing. Usage and setup instructions will be provided for the study.

Participants will contribute up to 7 overnight recordings in the home environment and will complete daily questionnaires detailing their experience.

The study may be completed in two distinct phases, with an analysis performed after each phase. Each phase is expected to last up to six weeks with the overall study duration taking up to 12 months.

Read the detailed description

The study may be completed in two distinct phases, with an analysis performed after each phase.

Phase 1 (Exploratory): A minimum of 10 and up to 12 participants will be recruited to identify any issues in using the app when used in conjunction with CPAP therapy (e.g. missed signals, inappropriate classification of breathing signals).

Phase 2 (Iterative Updates): Where changes to the algorithm or user interface are required, an additional 30 and up to 35 participants may be tested to provide design confidence. Conversely, if substantial issues are experienced and the time and effort required to address the issues is sufficiently large, the study may terminate before completion of phase 2.

Each phase is expected to last up to six weeks with the overall study duration taking up to 12 months.

Participants will be required to visit ResMed twice. The first visit will involve briefing of the study, consent form signatures, briefing on trial equipment and setup/usage instructions. The second (last) visit will involve going through the daily questionnaires with participants, collecting trial equipment and providing reimbursement for the study.

What participants receive

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

  • Drive appOther

    The Drive app will be used to monitor sleep metrics for users of CPAP therapy.

  • Non contact motion sensorDevice

    The non contact motion sensor will be used as a reference to the Drive app i.e. Drive app overnight recordings will be compared to the non contact motion sensor overnight recordings.

What is being measured

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

  1. Identify any failures when using the Drive app for users of CPAP therapy

    This will be based on:

    1. Subjective data from daily questionnaires sent out to participants
    2. Comparison between Drive app data with the non contact motion sensor and CPAP data

    The questionnaire has yes/no questions and a likert scale (from 0-10) that participants fill in to indicate how representative each nights sleep hypnogram is. For e.g. if the participant was awake between 12am-1am but the app reports that the subject is in deep sleep, this will be captured in the questionnaire.

    Metrics including accuracy, correlation, total cohens kappa will be used for each signal recorded by the app which will be used to compare to the data from the reference devices.

    Measured: 12 months (includes Phase 1 and Phase 2 and interim data analysis)

Secondary outcomes (3)
  1. Evaluate usability of the Drive app

    This will be based on subjective data from daily questionnaires sent out to participants.

    This data will be captured from comments by the participants in the daily questionnaires.

    Measured: 12 months (includes Phase 1 and Phase 2 and interim data analysis)

  2. Compare subjective sleep quality data with data generated on the app.

    This will be based on subjective data from daily questionnaires sent out to participants.

    The questionnaire has yes/no questions and a likert scale (from 0-10) that participants fill in to indicate how representative each nights sleep hypnogram is. For e.g. if the participant was awake between 12am-1am but the app reports that the subject is in deep sleep, this will be captured in the questionnaire.

    Measured: 12 months (includes Phase 1 and Phase 2 and interim data analysis)

  3. Compare the Drive app sleep data to data from the reference devices.

    Analyses will be performed to compare the Drive app data with the non contact motion sensor and CPAP device.

    Metrics including accuracy, correlation, total cohens kappa will be used for each signal recorded by the app which will be used to compare to the data from the reference devices.

    Measured: 12 months (includes Phase 1 and Phase 2 and interim data analysis)

Questions about this trial

What is this clinical trial studying?

A study testing Drive app and Non contact motion sensor in people with Obstructive Sleep Apnea, run by ResMed at 1 site in Australia.

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 11 inclusion and 6 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: status not confirmed, as of the sponsor's last update on 5 Aug 2020. 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 Australia. 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?

Results are not available in the source record.

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

Contact Neha Banodkar ((02) 8884 2656, neha.banodkar@resmed.com.au), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Identify any failures when using the Drive app for users of CPAP therapy (time frame: 12 months (includes Phase 1 and Phase 2 and interim data analysis)). 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 5 Aug 2020.
