Long-Term, Open Label Atomoxetine Study

Phase 3CompletedNCT00190684

Eli Lilly and Company1,553 enrolled

Overview

To learn about the safety and any side effects of atomoxetine when given to children and adolescents for about 5 years (long-term) and to learn whether atomoxetine can help children and adolescents with attention-deficit/hyperactivity disorder (ADHD) who take the drug for about 5 years (long-term). Study participants can be atomoxetine naive, atomoxetine experienced whose therapy has been interrupted or, atomoxetine experienced on a known stable dose.

Outcomes

Primary Outcomes

Categorical Changes in Vital Signs (Blood Pressure [BP], Pulse, Weight, Temperature) During the Study

Vital signs were assesed categorically using the term high for BP, high and low for pulse and temperature, or decreased for weight. For BP, high was an increase to a value above the 95th percentile of the National Institute of Health (NIH) values. For pulse, high was an increase of at least 25 beats per minute to at least 110, and low was a decrease of at least 20 beats per minute to at most 65 beats per minute. For temperature, high was an increase of at least 1 to 37.7 and low was a decrease of at least 1.3 to at most 35.6. Decrease in weight was marked by a reduction of at least 3.5%.

Time frame: baseline, 5 years

Change From Baseline to 5 Year Endpoint in Weight, Height, and Body Mass Index (BMI) Percentile Stratified by Baseline Quartile

Patients were assessed for changes in weight, height, and BMI. BMI is an estimate of body fat based on body weight divided by height squared.

Time frame: baseline, 5 years

Change From Baseline to 5 Year Endpoint in Electrocardiogram (ECG)

Patients were assessed for changes in ECG. The RR interval is the time duration between two consecutive R waves of the ECG. The QRS interval is the beginning of Q to the end of the S wave. The QT interval is a measure of time between the start of the Q wave and the end of the T wave and is dependent on the heart rate. A corrected QT interval (QTc) has been corrected in order to aid interpretation. QTbz is the QT interval using Bazett's correction formula. QTfr is the QT interval using Fridericia's correction formula.QTdat is the QT interval using a data specific correction method for children.

Change From Baseline to 5 Year Endpoint in Heart Rate

Patients were assessed for changes in heart rate using electrocardiogram.

Time frame: baseline, 5 years

Number of Patients Meeting Committee for Proprietary Medicinal Products (CPMP) Categorical QTc Interval Criteria Part I (Numerical Increase)

Time frame: baseline through 5 years

Number of Patients Meeting CPMP Categorical QTc Interval Criteria Part II (Interpretation at Baseline and Endpoint)

QT interval is a measure of time between the start of the Q wave and the end of the T wave and is dependent on the heart rate. A corrected QT interval (QTc) has been corrected in order to aid interpretation. QTbz is the QT interval using Bazett's correction formula. QTfr is the QT interval using Fridericia's correction formula. QTdat is the QT interval using a data specific correction method for children. For Males: Normal is \<430 ms, Borderline is \>=430 ms and \<450 ms, Prolonged is \>=450 ms. For Females: Normal is \<450 ms, Borderline is \>=450 ms and \<470 ms, Prolonged is \>=470 ms.

Time frame: baseline through 5 years

Number of Participants With Abnormal Laboratory Analytes During the Study

Standard reference ranges from Covance Laboratories were used in the determination of abnormal high and low values based on age and gender, where appropriate. Aspartate aminotransferase (AST); serum glutamic oxaloacetic transaminase (SGOT); units/liter (U/L); alanine aminotransferase (ALT); serum glutamic pyruvic transaminase (SGPT); millimoles/liter (mmol/L); grams/liter (g/L); micromoles/liter (umol/L); millimoles/liter-iron (mmol/L-Fe); trillion/liter (TI/L)or 10\^12 units/liter; Giga/liter (GI/L)or 10\^9 units/liter; femtoliters (fL); urinalysis (UA)

Time frame: baseline through 5 years

Number of Participants in Each Tanner Stage (Pubic Hair) by Age Group

Secondary Outcomes

Change From Baseline to 5 Year Endpoint in Attention-Deficit/Hyperactivity Disorder Rating Scale-IV-Parent Version: Investigator Administered and Scored (ADHDRS-IV-Parent:Inv) Total Score and Subscale Scores

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. Hyperactive/Impulsive and Inattention Subscales consisted of 9 items each, for total subscale score range of 0 to 27. ADHD Index Subscale consisted of 12 items, for total score range of 0 to 36.

Time frame: baseline, 5 years

Change From Baseline to 5 Year Endpoint in Clinical Global Impressions-Attention-Deficit/Hyperactivity Disorder-Severity (CGI-ADHD-S) Score

Measures severity of the patient's overall severity of ADHD symptoms (1=normal, not at all ill; 7=among the most extremely ill patients).

Time frame: baseline, 5 years

Change From Baseline to 5 Year Endpoint in Conners' Parent Rating Scale-Revised: Short Form (CPRS-R:S) Subscale Scores

A 27-item rating scale (0 \[not at all/never\] to 3 \[very much true/very often\]) completed by the parent to assess problem behaviors related to ADHD. Subscales: Oppositional, Cognitive Problems, Hyperactivity, and ADHD Index. Subscale total scores range from 0 to 18 for all subscales except ADHD Index which ranges from 0 to 36.

Time frame: baseline, 5 years

Change From Baseline to 5 Year Endpoint in the Stroop Word Color Test

Only patients who took the Stroop Color Word Test in a previous atomoxetine study were required to complete the Stroop in this study. Stroop measures inhibition of dominant response and interference control. Patients were given tasks of recognition (colors), reading (where a word represents a color), and interference (reading words written in different colors). There were 100 items for each of the three categories and if they made it through 100 words with time remaining, they would repeat the list. Only a small number of patients had Stroop tests in this study, so no analysis was done.
