Recruiting at 1 site Phase 1, Phase 2 Obstructive Sleep Apnea

Obstructive Sleep Apnea study: Atomoxetine-plus-oxybutynin

Official title Combination Upper-Airway Electrical and Pharmacological Stimulation for Obstructive Sleep Apnea

ClinicalTrials.gov ID: NCT07577661

What this study is testing

What is Atomoxetine-plus-oxybutynin (80/5 mg) (AtoOxy)?

This is an investigational combination of two oral medicines being studied as a potential treatment for obstructive sleep apnea. It is designed to activate muscles in the throat to help keep the airway open during sleep.

Also referred to as AtoOxy.

Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
This study aims to find out if combining a new medication with an implanted nerve stimulator reduces breathing pauses during sleep more than using either treatment alone.
Who it's for
The study is looking for adults who have obstructive sleep apnea and already have a hypoglossal nerve stimulation device implanted.
What's involved
Participants will take part in a cross-over trial where they receive the implanted device stimulation, the new medication, both together, or a placebo in a random order to compare their effects.
Time commitment
The study involves multiple visits to test how well each treatment combination works on breathing during sleep.
  • Phase 2: a mid-size study of how well it works
  • You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance.

Who can take part

Ages 18 to 79

You may be able to join if

  • Ages 18 - 79 years
  • Diagnosed OSA
  • Implantation of a hypoglossal nerve stimulation device (HGNS, Inspire Medical) or scheduled for implantation (implantation required for randomization)
  • Willingness to withhold HGNS while testing therapies (up to 6 weeks with HGNS off [with/without pharmacotherapy] to assess benefits of HGNS therapy).

You likely can't join if

  • Any uncontrolled medical condition
  • Current use of the medications under investigation.
  • Issues relating to short-term withdrawal of HGNS therapy
  • Excluded: Occupational driving (truck drivers, fork-lift operation, taxi/uber drivers)
  • Excluded: History of traffic accidents attributable to sleepiness or fatigue (\<2 years).
  • Use of SNRIs/SSRIs or anticholinergic medications during the study.
