Summary
Brief summary
Currently, there is no pharmacological intervention for mild symptomatic obstructive sleep disordered breathing (SDB) in the form of loud habitual snoring, inspiratory flow limitation (i.e. upper airway resistance syndrome), or mild sleep apnea. Here the investigators study the effect on SDB of stimulating pharyngeal muscles during sleep with AD036. The key hypothesis of the study is that AD036 is superior to placebo on self-reported and objective measures of SDB severity.
