Official title
Effect of DAW2020 on Endotypic Traits in OSA
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
