Effects Of GW679769 On Sleep Onset And Maintenance,And Next Day Functioning In The Elderly And Non-elderly With Primary Insomnia

April 14, 2015 updated by: GlaxoSmithKline

A Randomized, Double-blind, Placebo-controlled, Cross-over Study to Evaluate the Effects of GW679769 on Polysomnographic Sleep Recordings, Subjective Sleep Assessment, and Daytime Cognitive Function in Elderly and Non-elderly Subjects With Primary Insomnia

This study is designed to find the optimal (best) doses of GW679769 that promote sleep onset and maintain sleep during two consecutive nights of dosing without significant next-day thinking impairment and drowsiness in subjects with primary insomnia.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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 and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Difficulty going to sleep and/or staying asleep for at least the past 3 months.
  • Insomnia must result in significant distress or impairment in functioning at home, socially or at work.
  • Otherwise good health with no significant or unstable medical disorder including psychiatric, neurological, endocrine, heart, lung or gastrointestinal disorders, drug/alcohol abuse, cognitive impairment, cancer or chronic pain conditions such as arthritis.

Exclusion Criteria:

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
Time Frame
Comparison of GW679769 and placebo on the average time needed to fall asleep after bedtime dosing on two consecutive nights, as assessed by electroencephalography and other physiological changes during sleep.
Time Frame: 48 Hours
48 Hours

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
Time Frame
Comparison of GW679769 and placebo on sleep maintenance and duration after bedtime dosing on two consecutive nights, as assessed by electroencephalography and subject diaries, and on next-day memory, alertness and physical coordination.
Time Frame: 48 Hours
48 Hours

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.
March 1, 2007

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.
