About this study

Official title: A Double-Blind Randomized Physiological Study Examining the Effects of Eszopiclone on the Arousal Threshold and Obstructive Sleep Apnea Severity

The purpose of this study is to find out whether taking eszopiclone (Lunesta) changes the breathing effort required to briefly wake people with obstructive sleep apnea from sleep (respiratory arousal threshold). We would like to see if taking eszopiclone can reduce the severity of obstructive sleep apnea in some people (those that have a low respiratory arousal threshold; i.e. wake up easily to respiratory stimuli).

Read the detailed description

Obstructive sleep apnea is an exceedingly common disease with major neurocognitive and cardiovascular consequences. The current primary treatment e.g. Continuous positive airway pressure (CPAP) is effective but poorly tolerated by many patients particularly those with mild-moderate disease. Secondary treatments such as oral appliances to advance the mandible or surgical procedures to enlarge the airway are commonly appealing to the patient. However, these approaches have only modest success in reducing apnea frequency to an acceptable level. Thus, finding tolerable and effective therapy for sleep apnea remains an important objective.

The causes of sleep apnea vary between patients. Targeted therapy according to the underlying causes of sleep apnea in individual patients is likely to be most effective. However, current therapeutic options for sleep apnea are quite limited. The purpose of this physiological research study is to determine if taking eszopiclone (Lunesta)changes the breathing effort required to briefly wake people with obstructive sleep apnea from sleep (the arousal threshold) and if administration of the sedative medication eszopiclone (Lunesta) to certain sleep apnea patients (those with a low arousal threshold ie wake up easily) would be beneficial.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Apnea Hypopnea Index

    number of respiratory events per hour of sleep Respiratory events last for at least 10 seconds and are associated with a decrease in blood oxygenation or a cortical arosual from sleep. AHI values are typically categorized as 5-15/hr = mild; 15-30/hr = moderate; and > 30/h = severe

    Measured: 8 hour In-Laboratory Polysomnogram (PSG)

Secondary outcomes (3)
  1. Arousal Threshold

    quantified using an epiglottic pressure transducer in CmH2O

    Measured: 8 hour In-Laboratory Polysomnogram (PSG)

  2. Nadir Overnight Oxygen Saturation

    Nadir overnight oxygen saturation (%)

    Measured: 8 hour In-Laboratory Polysomnogram (PSG)

  3. Sleep Duration

    total sleep duration

    Measured: 8 hour In-Laboratory Polysomnogram (PSG)

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Eszopiclone in people with Obstructive Sleep Apnea, run by Brigham and Women's Hospital at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Apr 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 18 Apr 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Apnea Hypopnea Index (time frame: 8 hour In-Laboratory Polysomnogram (PSG)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01102270, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Apr 2017.
