Inclusion criteria

* Between 18 to 65 years of age for men and 18-75 for women, inclusive, at the Screening Visit. * Mean AHI 10 to 45 events/h, inclusive * PGI-S: \>1 * BMI between 18.5 and 38 kg/m2 for men and 40 kg/m2 for women, inclusive.

Exclusion criteria

* Current clinically significant sleep disorder other than OSA * Clinically significant craniofacial malformation. * Clinically significant cardiac disease (e.g. rhythm disturbances, coronary artery disease or heart failure or hypertension requiring more than 2 medications for control). * Participants with a history of using devices for OSA treatment, including CPAP, oral or nasal devices, or positional devices, may enroll as long as the devices have not been used for at least 2 weeks prior to first PSG and are not used during participation in the study

Design outcomes

Primary

MeasureTime frameDescription
Change in Apnea-Hypopnea Index (AHI4) From Baseline: Combined AD109 Arms vs. PlaceboBaseline (mean of PSG Visits 2 and 3) to Day 21 and Day 28 (PSG Visits 5 and 6)Change in AHI4 (apnea-hypopnea index, 4% oxygen desaturation criterion; average respiratory events per hour of sleep) measured by in-lab polysomnography. Baseline was the mean of two pre-treatment PSG nights (Visits 2 and 3). Change from baseline was assessed at treatment PSG nights at approximately Day 21 (Visit 5) and Day 28 (Visit 6), modeled as repeated measures, with the reported value representing the model-based LS mean using equal (0.5/0.5) weighting between the Day 21 and Day 28 visits.

Change in Apnea-Hypopnea Index (AHI4) From Baseline: Combined AD504 Arms vs. PlaceboBaseline (mean of PSG Visits 2 and 3) to Day 21 and Day 28 (PSG Visits 5 and 6)Change in AHI4 (apnea-hypopnea index, 4% oxygen desaturation criterion; average respiratory events per hour of sleep) measured by in-lab polysomnography.
