Primary Outcome Measures:
  • Pittsburgh Sleep Quality Index [ Time Frame: baseline and post-treatment (at end of 5 weeks) ]

    The change in ISI and PSQI from baseline to end of study will be compared between the two groups.

    PSQI has a score range of 0-21, with lower the number being less sleep disturbances ISI has a score range of 0-28, with lower score meaning less insomnia symptoms

  • Insomnia Severity Index [ Time Frame: 5 weeks ]

    The change in ISI and PSQI from baseline to end of study will be compared between the two groups.

    PSQI has a score range of 0-21, with lower the number being less sleep disturbances ISI has a score range of 0-28, with lower score meaning less insomnia symptoms

Secondary Outcome Measures:
  • Daytime Sleepiness (Epworth Sleepiness Scale) [ Time Frame: baseline and post-treatment (at end of 5 weeks) ]
    Score of 0-24, with 24 being the most sleepy

  • Daytime Performance (Digit Symbol Substitution Test) [ Time Frame: baseline and post-treatment (at end of 5 weeks) ]

    DSST tests the number of correct digit-symbol pairs that an individual can identify within an allotted period (60-90 sec). It test memory and concentration, among other parameters.

    DSST score can range from 0-125, with 125 being the most number correct during the allotted time period.

  • Daytime Lung Function (Peak Flow Monitoring) in Liter/Min [ Time Frame: baseline and during treatment period (during 5th week) ]

melatonin agonist
Other Name: Rozerem
Placebo Comparator: 2: Placebo Drug: Ramelteon
melatonin agonist
Other Name: Rozerem

Detailed Description:
Subjects with insomnia comorbid with asthma will be randomized to placebo or ramelteon at night for 6 weeks.

Ages Eligible for Study:   18 Years to 60 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Ages 18 - 60 with both insomnia and asthma.
  • Insomnia:

    • a complaint of difficulty initiating sleep, difficulty maintaining sleep, or waking up too early or sleep that is chronically nonrestorative or poor in quality,
    • the sleep difficulty occurs despite adequate opportunity and circumstances for sleep, and
    • at least one form of daytime impairment related to the nighttime sleep difficulty must be present. The sleep complaint should be present on most days for at least 3 months.
  • Additional inclusion criteria include: a subjective TST <6.5 h and a subjective SL > 45 min per night; a mean LPS >20 min over 2 consecutive nights by polysomnography (neither night could have been <15 min); a habitual bedtime between 10 PM and 1 AM; and ISI score > 10 (based on 0-4 scale). LPS is defined as amount of time to the first 10 minutes of continuous sleep.
  • Asthma will be diagnosed based on suggestive clinical history and either

    • airway hyperresponsiveness indicated by a 20% or greater decrease in FEV1 in response to inhalation of methacholine at 8 mg/mL or less
    • bronchodilator-responsive expiratory airflow limitation (if FEV1 < 70% of predicted value or < 1.5 L, improving ≥200 mL and 12% in response to 180 µg of albuterol aerosol). In addition to the above criteria, patients should have well-controlled asthma as evidenced by ACQ score < 1.5.

Exclusion Criteria:

  • Primary sleep pathology, other than insomnia as assessed by sleep history and confirmed by polysomnography to exclude significant sleep apnea (RDI > 15), periodic leg movements (movement arousal index > 15), REM behavior disorder; or circadian sleep-wake disorders
  • History of cognitive or other neurological disorders;
  • History of DSM-IV criteria for any major psychiatric disorder, including mania or alcohol or substance abuse;
  • Depressive symptoms as assessed by the CES-D. Subjects with a score of 22 or greater indicates that the person may be suffering from a major depression and therefore, will be referred to their physician;
  • Unstable or serious medical conditions;
  • Current, or use within the past month, of psychoactive, hypnotic, stimulant or analgesic medications (except occasionally);
  • Shift work or other types of self imposed irregular sleep schedules;
  • Obesity (BMI > 35 Kg/m2); or
  • Pregnancy or desire to become pregnant during the study.
