About this study

Official title: A Placebo-Controlled, Randomized Trial of Eszopiclone for the Treatment of Bupropion- and Abstinence-Related Insomnia During Smoking Cessation

Objectives:

The primary objective of this study is to determine the efficacy of eszopiclone at treating sleep problems related to withdrawal from nicotine in healthy smokers attempting smoking cessation.

Read more

Sleep disturbances are a significant problem for smokers who are trying to quit smoking. Smokers may be more likely to have sleep problems and both nicotine withdrawal and agents used to aid smoking cessation (e.g., pharmacotherapies) may disrupt sleep. Lunesta (eszopiclone) is a medication that has been approved by the FDA to treat insomnia. Eszopiclone's efficacy for treating insomnia makes it a promising agent for treating nicotine withdrawal-related symptoms of sleep disturbance.

This study will be 7 weeks duration. All participants will begin taking Zyban at the beginning of week 1 and will be asked to try to quit smoking at the beginning of week 2. Participants will also begin to take Lunesta or matched placebo (3 mg qd x 6 weeks) on the target quit date at the beginning of week 2. All subjects will receive eight (8) weekly sessions of brief individual supportive smoking cessation counseling.

Hypothesis:

It is hypothesized that significantly fewer sleep problems will be reported by participants taking Lunesta as compared to placebo. Specifically, it is expected that participants taking Lunesta will report less difficulty falling and staying asleep, higher sleep quality, and less insomnia-related fatigue and distress than participants taking placebo.

What is being measured

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

  1. Level of Insomnia as Measured by the Insomnia Severity Index

    Insomnia Severity Index (ISI): 13-item self-report measure which examines symptoms of insomnia, consequences of insomnia, and subjective distress related to sleep problems. Subjects rate the symptoms and consequences of insomnia on a 5 point Likert scales. For example, subjects are asked to rate the severity of their insomnia (e.g., difficulty falling asleep from 0=none to 4=very severe). Scores on the first 7 items are summed for a total insomnia score ranging from 0-28.

    Measured: 6 weeks after target smoking quit date

Secondary outcomes (1)
  1. Smoking Abstinence as Measured by Self Reported Smoking and Confirmed by CO Level

    Endpoint abstinence will be defined as 0 cigarettes over the seven days prior to the subject's Timeline Follow-Back evaluation at the end of week 7 (end of trial) and a Carbon Monoxide (CO) level ≤ 5.

    Measured: 6 weeks after target smoking quite date

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Eszopiclone and Bupropion in people with Insomnia and Nicotine Dependence, run by Yale University 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 6 inclusion and 11 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: stopped early, as of the sponsor's last update on 9 May 2022. 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?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 4 Dec 2009). 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?

Level of Insomnia as Measured by the Insomnia Severity Index (time frame: 6 weeks after target smoking quit date). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 9 May 2022.
