Clinical Trial Summary

This study will recruit 66 patients with obstructive sleep apnea, comprising 33 men and 33 women, who have been referred to the sleep center by their doctors for polysomnograms (PSG). The subjects will undergo two overnight sleep PSG sessions at the sleep center. The interval between the two examinations will be at least 7 days, during which they will receive both a placebo and medication conditions, administered 1 hour before bedtime. The study drugs will include: (1) atomoxetine 80 mg and oxybutynin 5 mg; or (2) venlafaxine 37.5 mg; or (3) atomoxetine 80 mg and trazodone 100 mg. Endotypic traits will be estimated using the Phenotyping Using Polysomnography method. The primary outcome is the change in apnea-hypopnea index, and secondary outcomes include endotypic traits and sleep parameters.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Sleep quality	Sleep quality is assessed using a 3-point Likert scale ranging from 1 (very good) to 3 (very poor)	Baseline and one week
Other	Waking sleepiness	Waking sleepiness is assessed using a 4-point Likert scale ranging from 1 (very sleepy) to 4 (not at all sleepy).	Baseline and one week
Primary	Physiological parameter	Change in apnea-hypopnea index.	Baseline and one week
Secondary	Endotypic traits	Four endotypic traits, namely arousal threshold, upper airway collapsibility, loop gain, and upper airway muscle compensation, will be estimated using the Phenotyping Using Polysomnography method, specifically, a validated cloud-based Python application (PUPpy).	Baseline and one week
