July 31, 2013 updated by: Boston Children's Hospital

Double Blind, Placebo Controlled, Crossover Study of Extended Release Methylphenidate for Treatment of ADHD in Children With Epilepsy

This study will evaluate the safety and effectiveness of extended release methylphenidate (XR-MPH) in treating attention deficit hyperactivity disorder (ADHD) in children with both ADHD and epilepsy.

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

Epilepsy is a brain disorder in which clusters of nerve cells in the brain periodically send abnormal signals. The normal pattern of nerve cell activity, therefore, becomes disrupted, which can result in seizures. Some symptoms of epileptic seizures include the following: strange sensations, emotions, or behavior; convulsions; muscle spasms; and loss of consciousness. Children with epilepsy are at risk for other specific disorders, such as ADHD, one of the most common mental disorders in children. ADHD is characterized by impulsiveness, hyperactivity, and inattention. Approximately one third of children with epilepsy also have ADHD. Stimulant medication is a common treatment method for ADHD. The effect of stimulant treatment on epilepsy and seizure frequency, however, is unknown. This study will evaluate the safety and effectiveness of XR-MPH, a stimulant medication, in treating ADHD in children with both ADHD and epilepsy.

People interested in participating in this double-blind study will first attend two visits for interviews and evaluations to determine eligibility for participation. Upon study entry, participants will be randomly assigned to initially receive either XR-MPH or placebo. Medication dosages and duration in the study will depend on participants' weights. Participants will first take either immediate release MPH or placebo "A" for 1 day. Any participants who experience an adverse event will be removed from the study. On Day 2 of treatment, participants assigned to receive XR-MPH will begin taking it, and participants assigned to receive placebo will switch to placebo "B." This treatment phase will continue for 6 days to 4 weeks, depending on weight, and will then be followed by a 1-week medication washout period. Following the washout, participants will switch to the other treatment group for the remainder of the study and will receive either XR-MPH or placebo in the same manner. Participants will attend weekly study visits, at which they will receive medication and undergo assessments of ADHD symptoms and medication side effects. Blood will be drawn to assess medication levels at the first study visit and following both rounds of treatment. Participants who have trouble with transportation to and from the study site may complete some study visits via telephone. Upon study completion, all participants will be offered clinical treatment with the study physician. Follow-up visits will be held every 2 to 6 months for patients who choose to continue receiving care from the study physician.

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

6 years to 18 years (Child, Adult)

Accepts Healthy Volunteers

No
