Description

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

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Apnea-Hypopnea Index (AHI4) From Baseline: Combined AD109 Arms vs. Placebo
Time Frame: Baseline (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.
Baseline (mean of PSG Visits 2 and 3) to Day 21 and Day 28 (PSG Visits 5 and 6)
