Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 64 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

  • Males and females with a diagnosis of primary insomnia as defined in DSM-IV.
  • Habitual bedtime between 9:00 pm and 1:00 am.
  • No history or evidence of restless leg syndrome or periodic limb movement disorder or sleep apnea.
  • Patients must sign a written consent form.

Exclusion Criteria:

  • History of drug or alcohol abuse as defined in DSM-IV.
  • History of psychiatric disorders, including Major Depressive Disorder, Generalized Anxiety Disorder and delirium.
  • History of chronic obstructive pulmonary disease (COPD), seizures, sleep apnea, narcolepsy, circadian-rhythm sleep disorder, parasomnia or any sleep disorder other than chronic insomnia.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Average Change From Baseline - Latency to Persistent Sleep (LPS)
Time Frame: Baseline, Night 1, and Night 8 measurement
Average latency to persistent sleep is defined as the length of time elapsed between lights off and onset of persistent sleep (defined as the point at which 10 minutes of uninterrupted sleep has begun as determined by PSG) between Baseline and the average of nights 1 and 8.
Baseline, Night 1, and Night 8 measurement

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Average Change From Baseline - Wake After Sleep Onset (WASO) and Total Sleep Time (TST)
Time Frame: Baseline, Night 1, and Night 8 measurements for WASO and TST
Average wake after sleep onset was defined as the time spent awake between onset of sleep (latency to non-awake) and lights-on, as determined by PSG between Baseline, and the average of nights 1 and 8. Total sleep time (TST) was defined as the time spent sleeping between lights-out and lights-on, i.e., full night between Baseline, and the average of nights 1 and 8.
Baseline, Night 1, and Night 8 measurements for WASO and TST

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
November 1, 2007

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
