NCT04611750

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.

Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Between 25 to 70 years of age, inclusive
  • SRQ at screening ≥ 4 (at least mild impact of snoring)
  • ESS at screening ≤ 12 (absence of sleepiness)
  • BMI between 18.5 and 40 kg/m2, inclusive.
  • Use of specified contraceptive methods if appropriate
  • AHI ≥5-10, or AHI 0-\<5 if either:
  • Snoring frequency (100dB snoring for \>10% of sleep) by tracheal microphone, or
  • Flow limitation frequency (\>50% obstruction for \>10% of sleep).
  • PGI-S that improves by at least 1 point during AD036 run-in period
  • PGI-S that improves by at least 1 point during AD036 run-in period.

You may not qualify if:

  • Participants are excluded from the study if any of the following criteria apply:
  • History of narcolepsy
  • Clinically significant craniofacial malformation
  • Clinically significant cardiac disease (e.g., rhythm disturbances, coronary artery disease or cardiac failure) or hypertension requiring more than 2 medications for control.
  • Clinically significant neurological disorder, including epilepsy/convulsions.
  • History of schizophrenia, schizoaffective disorder or bipolar disorder
  • History of attempted suicide or suicidal ideation within 1 year prior to screening, or current suicidal ideation.
  • History of clinically significant constipation, gastric retention, or urinary retention.
  • Positive screen for drugs of abuse or substance use disorder
  • A significant illness or infection requiring medical treatment in the past 30 days.
  • Clinically significant cognitive dysfunction.
  • Untreated narrow angle glaucoma.
  • Women who are pregnant or nursing.
  • History of using oral or nasal devices for the treatment of OSA or snoring; may enroll as long as the devices are not used during participation in the study.
  • History of using devices to affect participant sleeping position for the treatment of OSA or snoring, e.g. to discourage supine sleeping position; may enroll as long as the devices are not used during participation in the study.
  • +38 more criteria
