The Evaluation of a New Nasal Mask for the Treatment of Obstructive Sleep Apnea

Study Overview
=================
Brief Summary
-----------------
This investigation is designed to evaluate the comfort, ease of use and performance of a trial nasal mask for the treatment of Obstructive Sleep Apnea (OSA) in the home environment.

Detailed Description
-----------------
The investigation is a prospective, non-randomized, non-blinded study. Up to 45 OSA participants who currently use a nasal, sub-nasal or pillows mask will be recruited. The study will involve a baseline (Visit 1) data gathering with the participant's PAP therapy and their usual mask. This will be followed by the participants being fitted with the trial nasal mask by a mask fitting expert for use in-home (Visit 2). There will be a follow up phone call to gain feedback or address any issues after 3±1 days. The participant will then come in to return the mask (Visit 3) and give feedback on their experience using the mask in home in the form of a structured interview during Visit 3. If the participants prefer the trail nasal mask they will be asked if they would like to continue using the trial mask for a further six months in-home. There will be a follow up monthly phone call to gain feedback or address any issues during the extension. At the end of the six month extension period, the participants will return the trial nasal mask to the institution and give feedback on their experience using the mask in home in the form of a self-administered questionnaire. Participants will revert to their usual masks thereafter. Neither the participants nor the investigators will be blinded to the study.

Interventional Model Description: After a period of baseline, all enrolled participants will be put on the same trial mask.
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Experimental: Experimental trial nasal mask<br>Experimental trial nasal mask: Participants will be placed on this arm for a total of 14±3 days from Visit 2. Participants will be using the trial nasal mask during this treatment arm. Participants on the extension will use this trial mask for a further six months after Visit 3. | Device: Device: Trial nasal mask (F&P)<br>* This trial nasal mask will serve as the participant's primary PAP/BPAP therapy mask for the duration of the trial period (from Visit 2 to Visit 3). For participants taking part in the study extension, they will be using the trial nasal mask as their primary PAP/BPAP therapy mask for 6 months after Visit 3.<br>* Other names: New nasal mask;|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants Objective Trial Mask Performance | Objective measure (determined from efficacy data recorded from the participants PAP/BPAP therapy device. Adequate therapy was evaluated by reviewing the Apnea Hypopnea Index (AHI) at baseline to intervention within each individual participants from their PAP therapy device reports. Maintenance of therapy was determined by evaluating the change in AHI. The below data demonstrates how many participants of the analyzed population demonstrated maintenance of therapy after using the new F&P nasal mask. | 14 ± 3 days in home | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants Trial Mask Overall Simplicity of Use | Determined from questionnaires - Subjective (uses a 5-point Likert scale measuring ease of use, from very simple, simple, average, challenging, very challenging). Results below represent percentage of respondents for each value. | 14 ± 3 days in home | 
| Number of Participants Subjective Trial Mask Comfort | Determined from questionnaires - Subjective (uses a 5-point Likert scale measuring comfort from very comfortable, comfortable, average, uncomfortable, very uncomfortable). Participants reported their subject views on mask comfort. Responses to each likert scale option are presented below as percentages. | 14 ± 3 days in home | 
| Number of Participants Overall Trial Mask Satisfaction | Determined from questionnaires and a sleep diary - Subjective (measuring overall mask satisfaction, includes discussion, questions around overall satisfaction and preference of the new F&P Nasal mask compared to participants' usual mask ). | 14 ± 3 days in home |
