ADHD Clinical Trial - Irritability in Children With ADHD & Emotion

Status Completed

Clinical Trial Summary

Objective: Emotion dysregulation is common among children with ADHD and associated with a broad range of adult psychopathology, which is similar to the longitudinal outcomes of childhood irritability. However, the profiles of irritability in children with ADHD and emotion dysregulation has been understudied. This study aimed to investigate the efficacy of methylphenidate and aripiprazole in the treatment of irritability in children with ADHD and emotion dysregulation. In addition, the clinical profiles and neuropsychological characteristics of irritability in children with ADHD were explored.

Clinical Trial Description

Methods: A three-step, open-label, 10 week pilot study was conducted. Methylphenidate (4 weeks), aripiprazole (4 weeks), and the combination (2weeks) were examined in sequence as the treatment for irritability in children with ADHD and emotion dysregulation, defined by the CBCL-Dysregulation Profile. The primary outcome was improvement of irritability as measured by Aberrant Behavior Checklist-irritability subscale (ABC-I). During the first step, the subjects received pharmacological treatment of methylphenidate with flexible dosage for 4 weeks. Those subjects who had suboptimal response to methylphenidate (reduction of ABC-I score < 25%) entered the second step and the medication was switched to aripiprazole. After 4 weeks of treatment, those whose ABC-I scores reduced < 25% entered the third step and received the treatment of combination of methylphenidate and aripiprazole for two weeks (3rd step). Clinical profiles of irritability were evaluated with the Affective Reactivity Index (ARI), the Strengths and Difficulties Questionnaire, the Social Adjustment Inventory for Children and Adolescents, and the Autism Behavior Checklist-Taiwan Version. The neurophysiological characteristics of the subjects were assessed by three Cantab subtests: Emotion Recognition Task, One Touch Stockings of Cambridge, and Spatial Working Memory. The aforementioned measurements were administered at baseline and at the end of each step. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
