Study of Lunesta Versus Placebo for Sleep Problems Related to Smoking Cessation and Zyban
Study Details
Study Description
Brief Summary
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.
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.

Outcome Measures
Primary Outcome Measures
- Level of Insomnia as Measured by the Insomnia Severity Index [6 weeks after target smoking quit date]
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.
Secondary Outcome Measures
- Smoking Abstinence as Measured by Self Reported Smoking and Confirmed by CO Level [6 weeks after target smoking quite date]
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.

Study Results
Participant Flow
Recruitment Details | Participants were recruited from the Greater New Haven area and surrounding communities through targeted television, radio, and newspaper ads, fliers, and referrals from clinicians. Recruitment occurred between July of 2007 and October of 2008. Approximately 900 phone screens and 12 in-person screens were completed during the course of the study. |
---|---|
Pre-assignment Detail | Major reasons for exclusion at phone screen were report of no sleep problems, use of illegal substances, psychiatric or medical exclusions, and low smoking. Major reasons for exclusion during the in-person screening process included withdrawal of informed consent, alcohol or illicit drug use, and low smoking. |
