Trial summary

Background: In patients with obstructive sleep apnea, automatic continuous positive airway pressure machines (autoCPAP) are said to be capable of identifying various breathing abnormalities during sleep and to correct them by increasing progressively the positive pressure applied to the airway.

About this study

Official title: Reliability of Automatic CPAP Devices. A Double Blind Dummy Controlled Phase 1 Study

Background: In patients with obstructive sleep apnea, automatic continuous positive airway pressure machines (autoCPAP) are said to be capable of identifying various breathing abnormalities during sleep and to correct them by increasing progressively the positive pressure applied to the airway. Once breathing becomes normal, pressure slowly declines. AutoCPAP devices have never been tested in Phase I studies. The investigators hypothesised that normal breathing would not be recognised as such, and that pressure would increase even in a normal subject.

Read the detailed description

Material and Methods: We will submit one normal (confirmed with two polysomnographies, PSG) subject to a double blind study. Pairs of PSG will be performed on successive days once a week, one night with a 4 cm water fixed pressure CPAP device, previously shown not to disturb the subject's sleep and breathing, the other night with one of five well known autoCPAP devices programmed to work between 4 and 15 cm H2O pressure. The same mask and headgear will be used throughout the study. The subject and the physicians reading the tracings will ignore which device is being used on which night.

What is being measured

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

  1. number of episodes of increases in applied positive pressure, duration of each episode, and maximal pressure attained

    Measured: one night

Secondary outcomes (1)
  1. reasons for pressure increase and consequences of the increase on sleep continuity

    Measured: one night

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing CPAP and autoCPAP in people with Obstructive Sleep Apnea, run by Cliniques universitaires Saint-Luc- Université Catholique de Louvain at 1 site in Belgium.

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 2 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 16 Feb 2010. 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 Belgium. 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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

number of episodes of increases in applied positive pressure, duration of each episode, and maximal pressure attained (time frame: one night). 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 NCT01064258, 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 16 Feb 2010.
