Evaluation of a Novel Auto-Adjusting Positive Airway Pressure Algorithm for the Treatment of Obstructive Sleep Apnea Clinical Study
This study aims to assess the effectiveness of an investigational algorithm in the treatment of obstructive sleep apnea.
Study details:
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.
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.

Study Plan
This section provides details of the study plan, including how the study is designed and what the study is measuring.
How is the study designed?
| Participant Group/Arm | Intervention/Treatment |
|---|---|
EXPERIMENTAL: Investigational algorithm
| Device: Investigational algorithm |
ACTIVE_COMPARATOR: Control algorithm
| Device: Control algorithm |
What is the study measuring?
Primary Outcome
| Measure | Description | Time Frame |
|---|---|---|
| Comparison of the algorithm efficacy (AHI) to a clinically relevant data | The mean residual AHI of the investigational algorithm will be compared against an excepted clinical benchmark of 5 using a one sample t test. | 8 weeks |
Secondary Outcome
| Measure | Description | Time Frame |
|---|---|---|
| Secondary endpoint: Device usage | Hypothesis: the investigational algorithm will be equivalent or better than the comparison algorithm. Objective statistics on "Device usage" in hours per day (Hrs) stored in the PAP device will be downloaded. These parameters will be captured from each arm of testing and results will be analysed and compared. | From enrolment to the end of each study arm (up to 8 weeks) |
| Secondary endpoint: Leak | Hypothesis: the investigational algorithm will be equivalent or better than the comparison algorithm. Objective statistics on "Leak" in litres per minute (L/min) stored in the PAP device will be downloaded. These parameters will be captured from each arm of testing and results will be analysed and compared. | From enrollment to the end of each study arm (up to 8 weeks) |
| Secondary endpoint: Pressure | Hypothesis: the investigational algorithm will be equivalent or better than the comparison algorithm. Objective statistics on "Pressure" in centimeters of water (cmH2O) stored in the PAP device will be downloaded. These parameters will be captured from each arm of testing and results will be analysed and compared. | From enrolment to the end of each study arm (up to 8 weeks) |
| Secondary endpoint: Subjective scores | Hypothesis: the investigational algorithm will be equivalent or better than the comparison algorithm and/or Criterion score of 6. Subjective scores will be collected from participants on each item (e.g. comfort, breathign comfort, ease of falling asleep). Scores will be collected using an 11-point Likert Scale where a score of 10 is considered very favorable whereas score of 0 is considered very unfavorable. | From enrolment to the end of each study arm (up to 8 weeks) |
