Comparison of Slow and Fast Transition From Stimulants to Atomoxetine in Children and Adolescents With Attention Deficit/Hyperactivity Disorder(ADHD)

Eli Lilly and Company112 enrolled

Overview

Children and adolescents with Attention Deficit Hyperactivity Disorder (ADHD) who are not tolerating or not responding well to stimulant therapy will be included in this study. Two different strategies for transition from Stimulant to Atomoxetine will be used: Slow (10 weeks) and fast (2 weeks). Changes in ADHD symptoms and tolerability of medication will be compared between the two different switching approaches.

Study B4Z-EW-LYFJ is a phase IV multicentre, open label, controlled study in approximately 120 patients with ADHD from 6 years to 16 years of age. After the screening period, patients will be randomized (centrally in a 1:1 ratio) either to a transition period of 10 weeks (slow switching arm) or to a transition period of 2 weeks (fast switching arm). After completion of the 10 week open phase patients will be treated for a further 4 weeks with atomoxetine.

Outcomes

Primary Outcomes

Change From Baseline in Attention Deficit Hyperactivity Disorder-Rating Scale (ADHD-RS-IV) Parent Version: Investigator Administered and Scored - Total Score at Week 10 Endpoint

Measures the 18 symptoms contained in the Diagnostic and Statistical Manual of Mental Disorders Fourth Edition, Text Revision (DSM-IV-TR) diagnosis of Attention-Deficit/Hyperactivity Disorder (ADHD). Individual item scores range from 0 (none/never or rarely) to 3 (severe/very often). Total scores range from 0 to 54. Higher score indicates greater severity of disease. Least squares means are adjusted for baseline, site, treatment, visit and treatment by visit interaction.

Time frame: Baseline, 10 weeks

Change From Baseline in ADHD-RS-IV Parent Version: Investigator Administered and Scored - Total Score at Week 2 Endpoint

Measures the 18 symptoms contained in the Diagnostic and Statistical Manual of Mental Disorders Fourth Edition, Text Revision (DSM-IV-TR) diagnosis of ADHD. Individual item scores range from 0 (none/never or rarely) to 3 (severe/very often). Total scores range from 0 to 54. Higher score indicates greater severity of disease. Least squares means are adjusted for baseline, site, treatment, visit and treatment by visit interaction.

Time frame: Baseline, 2 weeks

Secondary Outcomes

Change From Baseline in Global Impression of Perceived Difficulties (GIPD) Rating Scale - Patient Total Score at Week 10 Endpoint

The GIPD scale is a 5-item rating of ADHD-related difficulties (overall difficulties perceived in the morning, during school, during homework, in the evening, and over the entire day and night). For each item, difficulties during the past week are rated on a 7-point scale (1 = normal, not difficult at all; 7 = extremely difficult) and the mean of the 5 items is reported. Least square means are adjusted for baseline, site, treatment, visit and treatment by visit interaction.

Change From Baseline in Clinical Global Impression Severity (CGI-S) Rating Scale - Total Score at Week 10 Endpoint

The CGI- S is a single-item clinician rating of the severity of the participant's ADHD symptoms in relation to the clinician's total experience of ADHD participants. Severity is rated on a seven-point scale (1 = normal, not ill at all; 7 = among the most extremely ill patients). Least square means are adjusted for baseline, site, treatment, visit and treatment by visit interaction.

Change From Baseline in Child Health and Illness Profile Child Edition-Parent Report Form (CHIP-CE-PRF) - Domain Scores at Week 10 Endpoint

CHIP-CE-PRF consists of 76 items. The majority of items assess frequency of activities or feelings using a five-point response format. Standard scores (t-value) were established, with all domains and subdomains having a mean score of 50 and standard deviation (SD) of 10. Standard scores are expressed in SD units. T-score=\[(Score- Mean for the reference population \[Ref Pop\])\*10/SD for the Ref Pop\]+50. Higher scores mean better quality of life. Least square means are adjusted for baseline, site, treatment, visit and treatment by visit interaction.

Time frame: Baseline, 10 weeks

Change From Baseline in Treatment Satisfaction Preference Survey Mean Score at Week 10 Endpoint

The Treatment Satisfaction Survey consists of a five-question survey each rated on a 5 point scale (0=very satisfied/very likely, 4=very dissatisfied/not at all likely). The mean score over the items is reported.
