DAW2020 on OSA Endotypic Traits
Enrolling by invitation · Phase 1/Phase 2 · Has a placebo group
Conditions studied: Obstructive Sleep Apnea (OSA)
In brief
Obstructive sleep apnea (OSA) is common and has major health implications but treatment options are limited. Some OSA patients with low arousal threshold wake up prematurely during an obstructive event and do not have time for spontaneous upper airway (UA) dilator muscle recruitment. As a consequence they are exposed to apnea and hypopnea cycling. In this protocol the investigators will test the effect of DAW2020 administered before sleep on OSA phenotype traits and OSA severity during sleep.

You may qualify if…
- Moderate-to-severe OSA (AHI ≥ 15 events/hr)
You may not qualify if…
- All participants will be healthy and without major organ system disease that would preclude undergoing the physiological measurements.
- Use of medications expected to stimulate or depress respiration (including opioids, barbiturates, acetazolamide, doxapram, almitrine, theophylline, 4-hydroxybutanoic acid).
- Use of SNRIs/SSRIs.
- Conditions likely to affect OSA physiology: neuromuscular disease or other major neurological disorder, heart failure (also below), or any other unstable major medical condition.
- Sleep disordered breathing or respiratory disorders other than obstructive sleep apnea:
- Other sleep disorders: periodic limb movements (periodic limb movement arousal index > 10/hr), narcolepsy, or parasomnias.
