Conditions

Obstructive Sleep Apnea

Brief summary

This is a randomized, 3-Period, Placebo-Controlled, Crossover, phase 2 clinical study to examine the efficacy and safety of AD036 versus placebo or atomoxetine in patients with obstructive sleep apnea.

Detailed description

The study is designed to examine the efficacy and safety of AD036 to treat obstructive sleep apnea. The study is a three-period single-dose randomized crossover design in which patients will undergo overnight Home Sleep Apnea Testing (HSAT) with dosing of one of the following 3 treatments: AD036, Atomoxetine, or Placebo. Participants will return 1 week after their final crossover HSAT for an end of study (EOS) Visit.

Inclusion criteria

* Male or Female, between 25 to 65 years of age, inclusive, at the Screening Visit. * AHI 10 to \<20, or AHI ≥20 if meets PSG criteria

Exclusion criteria

* 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. A medication for these purposes is defined by dosage form, such that a combination antihypertensive medication is considered 1 medication * CPAP should not be used for at least 2 weeks prior to first study PSG * History of using oral or nasal devices for the treatment of OSA may enroll as long as the devices are not used during participation in the study.

Recruitment details

5 clinical sites screened 101 participants 62 were randomized. This was an unblinded three period placebo controlled study. Participants who withdrew were not replaced.

Pre-assignment details

All participants were centrally randomized to one of 6 sequences (A - B - C, B - C - A, C - B - A, A - C - B, B - A - C, C - A - B). A 1-week minimum washout period occurred between each of the 3 arm assignments.

Outcome results

Primary

Apnea-Hypopnea Index

Apnea-Hypopnea Index(Disease severity is often defined based on the number of apneas and hypopneas per hour during sleep), AD036 vs. placebo

Time frame: 1 day

Population: The efficacy was analyzed using the mITT Population comprised of all participants who took at least 1 dose of any of the study treatments and had at least 1 measurement on the primary endpoint. Sixty (96.8%) patients were included in the mITT Population. Patients were analyzed for efficacy according to the treatment sequence into which they were randomized. Due to insufficient data quality of the home sleep test, AHI could not be determined in some treatment conditions.
