About

This study aims to assess the effectiveness of an investigational algorithm in the treatment of obstructive sleep apnea.

Full description

This is a blind, randomized cross over (or single arm depending on phase) study aiming to show that the new algorithm is efficacious in the treatment of obstructive sleep apnea (OSA). Furthermore, it allows for the comparison of relevant objective data parameters from the device and subjective outcomes in comparison to an established algorithm.

This study is planned in two phases. Phase 1 aims to gain confidence that the algorithm is functioning as intended, and allow for minor modifications to be made to the software before proceeding to Phase 2.

Phase 2 aims to assess the performance of the algorithm in a broader range of participants to capture data and subjective feedback comparing the users experience between the new algorithm and the control algorithm.

After the conclusion of phase 1 and 2, an optional extended trial period will be offered to participants who indicate that the experience on the investigational device was satisfactory and would like to continue using the algorithm will be included in an optional extended trial period.

The study will be conducted in the home environment. Participants who met the inclusion/exclusion criteria will be contacted. Participants will be explained the details of the trial and those who wish to take part will be invited to a selected site for the first study visit. In addition, subjects may be asked if they are willing to wear a wearable during both day and night (unless charging) for the duration of the study iteration. The wearable will be a commercially available wellness wearable that collects data to provide information about sleep and activity.

Visit 1 Participants will provide written informed consent. Participants will be set up on the algorithm they are first randomized to. If the participant and assessor are happy to proceed, the participants will take the device home to trial the first randomized algorithm, participants will be asked to complete a questionnaire regarding their therapy experience.

Visit 2 Participants will then be switched to the alternative algorithm and take the study device home to test. After trialling the second algorithm, participants will be asked to complete a questionnaire regarding their therapy experience and overall preferences.

Note: Visit 2 is not required if a cross over is not required in Phase 1.

Visit 3 The participant will return the investigational device to the assessor. The participants' questionnaire responses will be reviewed. Participants will be reimbursed. This concludes the participation in the study.

Investigational algorithm
Experimental group
Description:
The participants will trial the investigational algorithm and the control algorithm in a randomized order. Each will be used for up to 4 weeks in the home environment in place of their own device/therapy. The study device will be set up to align with the majority of the participants current therapy settings.
Treatment:
Device: Investigational algorithm
Control algorithm
Active Comparator group
Description:
