Trigeminal Nerve Stimulation for Attention Deficit Hyperactivity Disorder (ADHD)

March 23, 2016 updated by: James McGough, University of California, Los Angeles

An Eight-Week, Open Trial Pilot Investigation of Trigeminal Nerve Stimulation for Attention Deficit Hyperactivity Disorder (ADHD)

This proposal seeks to obtain preliminary data on the potential efficacy, tolerability, and feasibility of trigeminal nerve stimulation (TNS) as a treatment for Attention-Deficit/Hyperactivity Disorder (ADHD). If successful, this open-label, exploratory, pilot study will provide a basis for a federal grant application and larger controlled trials.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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.

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

7 years to 14 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • male and female youth age 9 to 14 years with Diagnostic and Statistical Manuel -IV (DSM-IV) ADHD, combined subtype as determined by Kiddie Schedule for Affective Disorders and Schizophrenia (KSADS) and clinical interview
  • minimum scores of 12 on both the inattentive and hyperactive/impulsive subscales of the baseline ADHD-Rating Scale (ADHD-RS)S
  • Clinical Global Impression- Severity (CGI-S) score at baseline
  • no current medications with central nervous system (CNS) affects
  • parents able and willing to monitor proper use of the stimulation device and complete all required rating scales.

Exclusion Criteria:

  • impaired functioning to a degree that requires immediate initiation of ADHD medication in the opinion of the parents and/or investigator; 2) current diagnosis of pervasive developmental disorder or major depression.
  • history of lifetime psychosis or mania
  • current suicidality
  • history of seizure disorder, tic disorder, or head injury with loss of consciousness.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: trigeminal nerve stimulation
Open label treatment with trigeminal nerve stimulation in an 8-week trial.
Device: EMS 7500 Digital Muscle Stimulator
A standard FDA approved transcutaneous electrical nerve stimulation (TENS) unit will be used to apply low intensity stimulation to the trigeminal nerves during sleep.

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
ADHD-IV Rating Scale (ADHD-RS)
Time Frame: Baseline and Week 8.

A standard, frequently used, clinician completed measure of Diagnostic and Statistical Manual -IV (DSM-IV) ADHD symptoms.

Scale ranges from 0 (best) to 54 (worst).

Unit of Measure - units on a scale.

Outcome value reflects change from baseline at endpoint (Week 8) in ADHD-RS.
Baseline and Week 8.

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
Clinical Global Impression - Improvement (CGI-I)
Time Frame: Week 8

A global measure of clinical improvement compared with baseline.

A standard clinical trials rating scale with value from 1 (very much improved) to 7 (very much worse).

Unit of measure - percentage improved based on CGI-I scores of 1 and 2 versus all others.
Week 8
Conners Global Index - Parent
Time Frame: Baseline and Week 8.

A standard, parent completed measure of ADHD symptoms.

Scale range from 0 (best) to 27 (worst).

Unit of Measure - units on a scale.

Outcome value reflects change from baseline at endpoint (Week 8).
Baseline and Week 8.
Attention Network Task - Incongruent Reaction Time
Time Frame: Baseline and Week 8.

Laboratory measure of response inhibition. The measure assessed the reaction time in milliseconds (ms) using the Attention Network Task (ANT), which is a computerized test designed to evaluate the efficiency of an attention network.

Outcome measure represents a change from Baseline at Week 8 for the ANT - Incongruent reaction time. Lower reaction time is consider a better outcome.

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.
