The objective of this study is to determine the effect of dexmedetomidine infusion on the Apnea / Hypopnea Index (AHI) of individuals with previously documented obstructive sleep apnea. We hypothesize that dexmedetomidine infusion may reduce the AHI in patients with obstructive sleep apnea (OSA).

Condition Intervention Phase
Obstructive Sleep Apnea
Drug: Dexmedetomidine
Drug: Placebo
Phase 2
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Dexmedetomidine for Sedation in Individuals With Obstructive Sleep Apnea

Further study details as provided by Duke University:

Primary Outcome Measures:
  • Apnea Hypopnea Index [ Time Frame: 8 hour sleep study ]
    The primary outcome is frequency of apnea or hypopnea as measured by the apnea hypopnea index

Secondary Outcome Measures:
  • Sleep Architecture [ Time Frame: During 8 hour sleep study ]
    Additional measures of sleep architecture will be made: sleep onset latency, duration of time spent in rapid eye movement (REM) and non-rapid eye movement (NREM) sleep, sleep efficiency, and number of arousals

Enrollment: 0
Study Start Date: March 2015
Estimated Study Completion Date: November 2015
Estimated Primary Completion Date: May 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Dexmedetomidine infusion
Dexmedetomidine 0.5 mcg/kg loading dose administered over 20 minutes, followed by 0.6 mcg/kg/hr infusion for 1 hour and 40 minutes
Drug: Dexmedetomidine
Other Name: Precedex
Placebo Comparator: Placebo
Normal saline infusions will be administered over 4 hours at rates mimicking the DEX infusion rate
Drug: Placebo


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • All individuals who have previously undergone diagnostic polysomnography in the Sleep Lab which documented significant OSA, and who have not undergone any changes that are likely to alter the severity of their condition since the time of their diagnostic sleep study (loss of weight; surgical therapy for OSA; removal of tonsils; discontinuation of medications likely to affect arousal or respiratory function, etc.) are eligible to participate. Subjects will be identified as they complete outpatient sleep studies or from records of previous sleep studies performed in the Duke Sleep Laboratory. After obtaining informed consent, subjects will be screened by history and physical examination, 12-lead electrocardiogram, and comprehensive metabolic profile.

Exclusion Criteria:

  • Exclusion criteria will include a history of illicit drug or alcohol dependence, impaired hepatic (aspartate aminotransferase or alanine aminotransferase > 2x upper limit of normal range) or renal function (receiving dialysis or serum creatinine > 1.5 mg/dL), high-grade (> 1st degree) heart block, or known allergy to dexmedetomidine.
