Plain English Summary

Background and study aims
We are carrying out a study on 30 subjects with documented Obstructive Sleep Apnoea (OSA). Obstructive sleep apnoea is the most common type of sleep apnoea and is caused by obstruction of the upper airway. It is characterized by repetitive pauses in breathing during sleep, despite the effort to breathe. Continuous Positive Airway Pressure (CPAP) is the first line medical therapy for treatment of OSA. A CPAP device is used when the subject is asleep and increases pressure in the throat to stop the airways collapsing when the subject breathes in.
In this study subjects will use the PR1 REMstar Auto with P-Flex (a CPAP device) to treat their sleep apnoea. Our goal is to find out if the PR1 REMstar Auto with P-Flex will reduce the subjects Apnoea Hypopnoea Index to an acceptable level. We will also look at other features of the subjects sleep report (polysomnography), daytime sleepiness, how often the subjects uses the device, how comfortable the device is to use and the pressure levels delivered by the device.

Who can participate?
Men and Women with documented Obstructive Sleep Apnoea, confirmed by polysomnography who are aged >21

What does the study involve?
Suitable subjects who have had a recent sleep study (polysomnography) will be invited to take part in this study. Subjects will be required to attend the sleep clinic three times throughout the study at set intervals. At the first visit subjects will be required to undergo a medical examination (to collect age, gender, height, weight, BMI, waist and neck measurements), complete a questionnaire and receive training on the device and mask to be used in the study. At the second and third visit the medical examination will be repeated (weight, BMI, waist and neck measurements), subjects will need to complete two questionnaires and the data recorded on the device will be retrieved. In addition at the third visit subjects will be required to undergo an overnight sleep study at the sleep centre using the study device.
At the end of the study we will look at all of the data collected to find out if the PR1 REMstar Auto with P-Flex device treated the subjects obstructive sleep apnoea to an acceptable level.

What are the possible benefits and risks of participating?
We believe that PR1 REMstar Auto with P-Flex reduces the Apnoea Hypopnoea Index, to an acceptable level in patients with measured documented OSA. Furthermore PR1 REMstar Auto with P-Flex changes other indices of the polysomnography study in an acceptable manner in patients with documented OSA. It is hoped that PR1 REMstar Auto with P-Flex reduces daytime sleepiness to an acceptable level and that minimally acceptable compliance levels can be achieved by patients with documented OSA who use the PR1 REMstar Auto with P-Flex. We also believe that the PR1 REMstar Auto with P-Flex is comfortable and easy to use.
We believe that the risks of providing positive airway pressure therapy with the PR1 REMstar Auto with P-Flex are no greater than the risks encountered with other assisted PAP devices. We believe that no significant risks will be posed to the subjects participating in this protocol, as the study is non invasive, use of the devices will be monitored by trained clinical staff in the sleep laboratory and the PAP equipment has been tested to ensure safety. The patient can also easily remove their interface device should it become uncomfortable or make breathing difficult.
Rarely, there may be skin irritation in response to the substance used to attach some of the electrodes. Other potential side effects of PAP therapy may include: ear discomfort, conjunctivitis, skin abrasions due to non-invasive interfaces and gastric distension, all of which are quite uncommon. Thus, we believe that the risks and discomfort associated with participation in this study are minimal.

Where is the study run from?
Clinique La Louviere, 69 rue de la Louviere, 59800 Lille, France

When is the study starting and how long is it expected to run?
It is anticipated that recruitment will start in October 2012. Subjects will be enrolled for about 84 days.
