A Study of Cranial Electrotherapy Stimulation as an Add-on Treatment for Tic Disorders (SCATT) (SCATT)

October 10, 2018 updated by: Xijing Hospital

A Double-blind, Randomized, Sham-controlled Study of Cranial Electrotherapy Stimulation as an Add-on Treatment for Tic Disorders in Children and Adolescents(SCATT)

Tic disorders is recognized as a neuropsychiatric disease. The treatments of tic disorders include drug therapy, psychotherapy and physical therapy. As a non-invasive therapy, cranial electrotherapy stimulation(CES) is approved to have few side effects and applied in various areas, especially in psychiatric diseases. However, up to now there have been no results about the effects of CES in the treatment of tic disorders.The investigators hope CES could offer a useful approach for treating tic disorders.

Study Overview

Status

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

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 investigators will conduct a randomized, double-blind, sham-controlled trial to determine the efficacy of CES as an add-on treatment for tic disorders (SCATT). The study will be conducted at an outpatient, single-center academic setting. A total of 100 patients aged 6 to 17 years with tic disorders and lack of clinical response to 4 weeks' pharmacotherapy will be enrolled. Patients will be randomly into 2 groups and given 4 weeks' treatment, including 40 daily 30-minute sessions of active CES(500μA~2mA) or sham CES(lower than 100μA) on weekdays. Change in Yale Global Tic Severity Scale (YGTSS) is considered to be the primary outcome. The secondary outcome is the changes in Clinical Global Impression (CGI) and Hamilton Anxiety Scale (HAMA). Assessments will be performed at baseline, week 2, week 4 and week 8. Adverse events(AE) will be also evaluated.

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.

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: Intervention Arm
Participants will receive 40 sessions in 4 weeks, for twice daily on weekdays from Monday to Friday. Each session will be performed for 30 minutes. The current intensity will be adjusted continuously from 500 μA~2mA.
Device: Cranial Electrotherapy Stimulation(CES)
Cranial electrotherapy stimulation (CES) has been known as a kind of noninvasive treatment, which applies pulsed, weak electrical current to head through two electrodes that placed on the earlobes. The current intensity could be adjusted continuously from 500 μA~2mA.
Sham Comparator: Sham Arm
Participants will receive 40 sessions in 4 weeks, for twice daily on weekdays from Monday to Friday. Each session will be performed for 30 minutes. The current intensity will be adjusted lower than 100 μA.
Device: sham Cranial Electrotherapy Stimulation( sham CES)
Cranial electrotherapy stimulation (CES) has been known as a kind of noninvasive treatment, which applies pulsed, weak electrical current to head through two electrodes that placed on the earlobes. The sham CES devices were identical to the active device, except the ear clip electrodes emit electricity intensity of lower than 100 μA.

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
Changes in Yale Global Tic Severity Scale (YGTSS) score
Time Frame: 8 weeks
Change in Yale Global Tic Severity Scale (YGTSS) at baseline and week 2, 4, 8. The YGTSS is applied by means of a semistructured interview with multiple informants (generally, the parents) who assess the child's tics over a period of at least one week.
8 weeks

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
Changes in Clinical Global Impression (CGI) score
Time Frame: 8 weeks
Change in Clinical Global Impression (CGI) between groups at baseline and week 2, 4, 8.
8 weeks
Changes in The Hamilton Rating Scale for Anxiety (HAM-A) score
Time Frame: 8 weeks

Change in The Hamilton Rating Scale for Anxiety (HAM-A) at baseline and week 2, 4, 8.

The HAM-A consists of 14 items, each defined by a series of symptoms, and measures both psychic anxiety (mental agitation and psychological distress) and somatic anxiety (physical complaints related to anxiety). Scores range from 0 to 56 where 14-17 indicates mild anxiety, 18-24 indicates moderate anxiety and scores of 25 and over indicate severe anxiety.
8 weeks
adverse effects
Time Frame: 8 weeks

Any adverse event notified spontaneously by the subject, or observed by the research team will be recorded on the form designed for this purpose. The researcher will classify the intensity of adverse events in accordance with the following scale: Mild: some discomfort experienced but not such as to interrupt normal daily activity.

Moderate: sufficient discomfort to reduce or notably affect normal daily activity. Severe: provoking incapacity to work or perform normal daily activity.
8 weeks
