Effects of Eszopiclone and Lemborexant in People With OSA With a Low Arousal Threshold Who Have Difficulty Sleeping

Sponsor: Flinders University

Summary

Insomnia and obstructive sleep apnoea (OSA) are very common conditions, collectively estimated to affect 2 billion people globally, and share many of the same symptoms. It is also common for people to have both insomnia and sleep apnoea (COMISA). Indeed, 30 to 40% of patients with chronic insomnia also fulfil the diagnostic criteria for OSA. These people can be particularly challenging to treat with conventional therapy approaches. People get OSA for different reasons. One key cause is waking up too easily to minor airway narrowing episodes (a low arousal threshold). Accordingly, this study aims to increase the arousal threshold using a combination approach with a GABAergic and an orexin agent in appropriately selected individuals (i.e., the clinically relevant group of people with OSA with a low arousal threshold and difficulty maintain or initiating sleep). Sleep, breathing and next day performance will be compared across two monitored overnight sleep studies (placebo vs the study drugs).
