About this trial

Researchers want to identify which treatments for obstructive sleep apnea (OSA) work best and are easiest for patients to use consistently. Eligible participants will be randomly assigned one of three OSA treatments: traditional PAP therapy, a dental device, or a combination of two FDA-approved medications (atomoxetine and oxybutynin) that are currently approved for other conditions. Over the course of one year, participants will attend two in-person visits and take part in four phone check-ins to complete surveys, report any side effects, and discuss how well they are following their assigned treatment.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Obstructive sleep apnea (AHI >/= 5 per hour), diagnosed in the past 6 months

Two or more of the following symptoms: snoring, fragmented sleep, witnessed apneas, or daytime sleepiness

Willingness/ability to use any of the 3 treatments for OSA (PAP, dental device, or atomoxetine-oxybutynin)

Health insurance of any type

Disqualifiers

Prior treatment for OSA in past year

Central sleep apnea or narcolepsy

Contraindication for dental device (temporomandibular joint problems, severe periodontal disease, insufficient dentition)

Heart failure with reduced ejection fraction of </= 45%

Trial design

Design model

Parallel

Treatments tested in this trial

  • Positive airway pressure (PAP) therapy

    Device

    Positive airway pressure delivered via a nasal or face mask while a patient sleeps to keep the airways open.

  • Sleep dental device

    Device

    An oral appliance worn during sleep to move the lower jaw forward, which tightens soft tissues and widens the airway to prevent sleep apnea.

  • Atomoxetine-oxybutynin

    Drug

    The combination of two medications (atomoxetine-oxybutynin) can reduce obstructive sleep apnea by increasing upper airway muscle activity.

Treatment groups

Trial outcomes

Primary outcomes

1

Health-related quality of life

To compare the effectiveness of positive airway pressure (PAP) therapy versus dental device versus atomoxetine-oxybutynin for key patient centered outcomes in improving health-related quality of life over 12 months, as assessed by the PROMIS-29 v2.0.

Time frame
At 12 months

Secondary outcomes

1

OSA treatment effectiveness - Effective AHI score

To compare the effectiveness of PAP therapy versus dental device versus atomoxetine-oxybutynin for treatment of OSA over 12 months, assessed by the effective apnea hypopnea index (AHI). Effective AHI equals the sum of apneas and hypopneas with treatment and without treatment divided by hours of total sleep time.

Time frame
12 months
2

OSA treatment effectiveness - PROMIS-Sleep Related Impairment 8a

To compare the effectiveness of PAP therapy versus dental device versus atomoxetine-oxybutynin for treatment of OSA over 12 months, assessed via the PROMIS-Sleep Related Impairment 8a.

Time frame
12 months
3

Changes in systolic blood pressure

To compare the effectiveness of PAP therapy versus dental device versus atomoxetine-oxybutynin in improving systolic blood pressure (mmHg) over 12 months.

Time frame
12 months
4

Changes in diastolic blood pressure

To compare the effectiveness of PAP therapy versus dental device versus atomoxetine-oxybutynin in improving diastolic blood pressure (mmHg) over 12 months.

Time frame
12 months
