Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Single-arm, non-randomised, open-label
Device: F&P Licorice Mask
PAP/NIV Therapy Mask
Therapeutic Efficacy
Determined by Apnea-Hypopnea Index (AHI) recorded on PAP therapy machines after 14 days of use. The Apnea-Hypopnea index (AHI) is the sum of the apneas and hypopneas divided by the hours of sleep. AHI values are typically categorized as 5-15/hr = mild; 15-30/hr = moderate; and \>= 30/h = severe AHI is measured by dividing the total number of recorded apneas (complete breathing stops) and hypopneas (shallow breathing episodes) by the total number of hours a person slept during an overnight sleep study or using a PAP device. Higher AHI values represent worse outcomes. There is no maximum theoretical index score.
Time frame: Baseline and 14±5 days
Epworth Sleepiness Scale
All relevant time points used in the calculation in the Time Frame (e.g., baseline and 14±5 days). Note: change was calculated from two time points as the value at the later time point minus the value at the earlier time point (e.g., value at 14±5 days minus value at baseline). Change between two time points is reported. Scale range: 0 (minimum score) to 24 (maximum score) (higher scores represent worse outcomes)
Time frame: 14±5 days
Patient and Clinical Global Impression (PGI/CGI)
Determined by Patient Global Impression (PGI) and Clinical Global Impression (CGI) assessments completed at baseline and Day 14. Baseline symptom severity is assessed using a 6-point scale (1 = No symptoms to 6 = Very severe symptoms). Change from baseline is assessed using a 7-point scale (1 = Very much better to 7 = Very much worse; 4 = No change). Higher severity scores indicate worse symptoms. For change assessments, lower scores indicate improvement and higher scores indicate worsening. PGI is completed by the patient and CGI is completed by the investigator/clinician.
Time frame: Baseline and 14±5 days

Start is estimated for Sep 2026; primary completion for Apr 2027, 6 months later.
Of 115 industry-sponsored interventional studies with no phase under Sleep Apnea, Obstructive, half reached primary completion within 12 months of starting (the median), counting those still running; a quarter within 3 and three quarters within 21. This study's planned 6 months is below that.
Counting every sponsor, half of 623 studies reached it within 27 months; a quarter within 12 and three quarters within 50.
