Efficacy, Safety, and Tolerability of Ambien (Zolpidem) in the Treatment of Children Ages 6 to 17 With Attention Deficit Hyperactivity Disorder (ADHD)-Associated Insomnia (Zolkids)

April 6, 2009 updated by: Sanofi

Efficacy, Safety and Tolerability of Zolpidem in the Treatment of Children Aged 6 to 17 Years With ADHD-Associated Insomnia. A Multicentre, Randomized, Double-Blind, Placebo-Controlled Study

There has been an increased interest in the association between ADHD and sleep disorders over the past years. A high incidence of sleep disturbance, ranging from 10% to 70%, has been identified in ADHD children regardless of whether or not they are receiving stimulant therapy. This study will assess the safety and efficacy of zolpidem in children with ADHD associated insomnia.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.

Detailed Description

The study is being conducted in the United States. It consists of 3 segments:

  • Segment A: 2 to 21 day screening period
  • Segment B: 8-week double-blind treatment period
  • Segment C: 1-week follow-up period

Subjects will have a polysomnography in a sleep lab two times during the study (at baseline and between visit 4-5) and also be required to wear an actigraphy monitoring tool. There will be several questionnaires completed throughout the study: CGI-child, CGI-parent/legal guardian, ADHD Rating Scale-IV, and the Pediatric Daytime Sleepiness Scale.

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

2 years to 13 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Male or female between the ages of 6 and 17 years, inclusive
  • Children with diagnosed ADHD (as defined by the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision [DSM-IV-TR] criteria)
  • Complaint of childhood insomnia as defined by repeated difficulty with sleep initiation or consolidation that occurs despite adequate age, appropriate time, and opportunity for sleep
  • The sleep disturbance must not be attributable to either the direct physiologic effect of drug abuse or misuse of a prescribed medication.
  • Subjects should be stabilized on all long-term therapy, including treatment of ADHD, for at least one month prior to study entry.
  • Subjects, if females of childbearing potential (as determined by the initiation of menses), must have confirmed negative pregnancy test prior to randomization and be using a recognized effective method of birth control (oral, implant, depot or transdermal oestroprogestatives, intrauterine device, double-barrier with spermicide). Abstinence is an acceptable method of birth control for this study.

Exclusion Criteria:

  • Mental retardation
  • Autistic spectrum disorder
  • A history of sleep apnea
  • A history of bipolar disorder, conduct disorder, major depression, or generalized anxiety disorder (not obsessive compulsive disorder), as determined by clinical interview and DSM-IV-TR criteria
  • Current history of substance abuse/dependence
  • Known hypersensitivity to zolpidem or previous adverse experience with zolpidem
  • Pregnant or breast-feeding
  • Current use of hypnotics, antihistamines, melatonin, herbal products, or other sleep aids

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
Latency to persistent sleep (LPS) measured by polysomnography

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
Adverse events
Clinical Global Impression (CGI) Severity and Global Improvement item scores (from child and parent/legal guardian scales)
Actigraphy measures of sleep characteristics
ADHD Rating Scale-IV
School tardiness/Attendance Reports
PE, lab

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.
April 1, 2006

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.
