About this study

Official title: Performance Comparison of Compumedics Somfit Sleep Monitoring Device Against Home Sleep Apnoea Testing Device (Itamar WatchPAT) and Polysomnography

To study whether Somfit is substantially equivalent to the existing approved devices for full polysomnography and home sleep apnea testing

Read the detailed description

Sleep is recognized as one of the three pillars of health (i.e. nutrition, exercise and sleep). Poor quality and fragmented sleep leads to an increase in the risk for development of chronic health conditions. Given the importance of good quality sleep and its critical role in overall well-being, there is a need for regular monitoring and assessment of sleep quality in individuals. However, current technologies will only allow for this to be performed in sleep clinics and with the help of full polysomnography (PSG) systems which require the patients to spend a night at the clinic with several wired electrodes connected to their scalp. This "gold standard" technology is expensive and therefore does not allow to meet public health demand for diagnosis of sleep disorders, especially obstructive sleep apnea (OSA) and also can be uncomfortable for the patients and distort their natural sleep architecture. To solve this problem, Compumedics has recently developed a miniaturized, portable, automated and affordable sleep monitoring system with code name of "Somfit" which is attached to patients' forehead and can be used in the comfort of patients' home. While Somfit has already gained TGA approval, the aim of this study is to compare Somfit with the "gold standard" PSG and another approved portable sleep testing device, Itamar WatchPAT One, in terms of accuracy of characterising sleep neurological architecture and diagnosing OSA, with the objective of applying for the international regulatory approvals.

What participants receive

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

  • Compumedics Somfit HSAT device, WatchPAT HSAT device, Compumedics Grael /E-series PSG systemDevice

    Each intervention is a separate diagnostic device. They will all be operating at the same time

What is being measured

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

  1. The AHI difference between the test device (Somfit) and gold standard (PSG)

    AHI is the apnea hypopnea index, main measure of presence/severity of OSA (obstructive sleep apnea). it will test the null hypothesis that Somfit AHI is not equivalent to the AHI reported by PSG

    Measured: Data required for the primary outcome measure are generated in the course of single night sleep recording for every participant. Statistical estimation will be performed after completion of all sleep recordings

  2. The AHI difference between the test device (Somfit) and predicate device (WatchPAT)

    AHI is the apnea hypopnea index, main measure of presence/severity of OSA (obstructive sleep apnea). it will test the null hypothesis that Somfit AHI is not equivalent to the AHI reported by PSG

    Measured: Data required for this primary outcome measure are generated in the course of single night sleep recording for every participant. Statistical estimation will be performed after completion of all sleep recordings

Secondary outcomes (2)
  1. Difference between hypnogram percent agreements between WatchPAT and PSG, and between Somfit and PSG

    It will test the null hypothesis that the accuracy of sleep staging performed by the test device (Somfit) is inferior to that of the predicate device (WatchPAT)

    Measured: Data required for this outcome measure are generated in the course of single night sleep recording for every participant. Statistical estimation will be performed after completion of all sleep recordings

  2. Hypnogram percent agreement between Somfit and PSG

    It will test the null hypothesis that the accuracy of sleep staging performed by the test device (Somfit) is inferior to that demonstrated by the accredited sleep technologists

    Measured: Data required for this outcome measure are generated in the course of single night sleep recording for every participant. Statistical estimation will be performed after completion of all sleep recordings

Questions about this trial

What is this clinical trial studying?

A study testing Compumedics Somfit HSAT device, WatchPAT HSAT device, Compumedics Grael /E-series PSG system in people with Sleep-Disordered Breathing, run by Compumedics Limited 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 3 inclusion and 5 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 7 Feb 2024. 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?

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?

The AHI difference between the test device (Somfit) and gold standard (PSG) (time frame: Data required for the primary outcome measure are generated in the course of single night sleep recording for every participant. Statistical estimation will be performed after completion of all sleep recordings). The study lists 2 primary outcomes in all. 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 7 Feb 2024; AzTrials last refreshed its copy on 7 Nov 2026.
