NCT02365064

Brief Summary

The study will determine which of two different types of positive airway pressure (PAP therapy) modes are more effective in reducing sleep breathing events in chronic insomnia patients and in decreasing insomnia severity.

Outcome Measures

Primary Outcomes (1)

  • Insomnia Severity Index

    Change in insomnia severity from baseline to 4 months as measured by subjective questionnaire. The Insomnia Severity Index has seven questions. The seven answers are added up for a total score. Scores range from 0 - 28. A higher score indicates a more severe degree of insomnia.

    Baseline and 4 months

Secondary Outcomes (5)

  • Sleep Quality Rating

    Baseline and 4 months

  • Global Morning Rating

    4 months

  • Sleep Onset Latency

    4 months

  • Wake After Sleep Onset (WASO)

    4 months

  • Sleep Efficiency

    4 months

Study Arms (2)

Continuous Positive Airway Pressure

ACTIVE COMPARATOR

Continuous positive airway pressure (CPAP) intervention as active comparator. Provides a fixed pressure for both inspiration and expiration.

Device: AirCurve 10 ASV

Adaptive Servo-Ventilation

EXPERIMENTAL

Adaptive servo-ventilation (ASV) positive airway pressure as experimental intervention. Provides a higher pressure for inspiration and a lower pressure for expiration with changes in the pressure support level to meet a target minute ventilation.

Device: AirCurve 10 ASV

Interventions

Device is able to provide both ASV therapy and CPAP therapy modes.

Also known as: VPAP Adapt, AutoSet CS2
Adaptive Servo-VentilationContinuous Positive Airway Pressure

Eligibility Criteria

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

You may qualify if:

  • Primary complaint of insomnia when presenting at clinic
  • Diagnosis of moderate to severe insomnia through the Insomnia Severity Index (ISI) with a score ≥ 15
  • Meet diagnostic criteria of Insomnia Disorder (per American Academy of Sleep Medicine)
  • Diagnosis of SDB, either OSA as determined by an AHI ≥ 5 events/hour or UARS with a RDI ≥ 15 events/hour and AHI \< 5 events/hour
  • Naïve to treatment for sleep-disordered breathing (SDB), including CPAP, APAP, ASV; mandibular repositioning devices (MRDs), and any other nasal or oral therapy with a primary indication of treating SDB
  • Able to fully understand study information in English and sign informed consent

You may not qualify if:

  • Primary complaint of sleep-disordered breathing or issues with apneas during sleep
  • Severe respiratory disorder or severe sleep disorder such as restless leg syndrome (RLS), idiopathic hypersomnia, or narcolepsy
  • BMI \> 30 kg/m2
  • Epworth Sleepiness Scale (ESS) score ≥ 10
  • Frequent napping behavior, such as a few times a week or more
  • Anticipated changes to start or stop sedative or psychotropic medications during the course of the trial
  • Medical history of congestive heart failure (CHF) or other potentially unstable cardiac disease as well as chronic lung diseases or other debilitating medical conditions that manifest as more prominent in the patient's health compared to their sleep complaints
  • Daily use of opiate medications
  • Known contraindications to PAP therapy as listed in the indication for use
  • Requires a CPAP (fixed) pressure \> 20 cm H2O
  • Inability to comply with study procedures
