Who is the study for?

This trial is for men and women aged 21-65 with a physician's diagnosis of OSA, or suspected to have it, who are not active smokers/vapers and do not have uncontrolled high blood pressure, chronic lung disease requiring oxygen, recent hospitalization, heavy alcohol use, certain heart conditions, active cancer or other specific health issues. BMI must be between 20 - 35 kg/m2.Check my eligibility

What is being tested?

The study aims to understand why people develop Obstructive Sleep Apnea (OSA) and how this relates to the effectiveness of treatments like CPAP machines, eszopiclone medication for sleep aid, and supplemental oxygen therapy in managing symptoms such as sleepiness and high blood pressure.See study design

What are the potential side effects?

Possible side effects may include discomfort from wearing the CPAP device at night; dizziness, dry mouth or unpleasant taste from eszopiclone; and dry nasal passages from using supplemental oxygen.

Trial Design

2Treatment groups

Experimental Treatment

Group I: Usual PAP StartExperimental Treatment2 Interventions

After two initial baseline overnight studies, and two experimental overnight studies during which subjects will receive Eszopiclone (2mg before bedtime) or oxygen (4L/min via nasal cannula for the duration of the time in bed) in random order, subjects will remain untreated until they are set up with their clinically prescribed CPAP (typically takes about 8 weeks).

Group II: Early PAP StartExperimental Treatment3 Interventions

After two initial baseline overnight studies, and two experimental overnight studies during which subjects will receive Eszopiclone (2mg before bedtime) or oxygen (4L/min via nasal cannula for the duration of the time in bed) in random order, subjects will be set up with a loaner CPAP for 8 weeks to initiate therapy right away.
