Atomoxetine Asian Study in Adult Subjects With Attention-Deficit/Hyperactivity Disorder (ADHD)

The definition of a study adverse event was any unfavorable medical event, newly emerged or a deterioration of a preexisting condition, in other words any untoward medical occurrence in a patient administered a pharmaceutical product, without regard to the possibility of a causal relationship, that occurred after the visit for informed consent and up to the visit for completion of administration, or discontinuation.

Conners' Adult Attention-Deficit Hyperactivity Disorder (ADHD) Rating Scale-Investigator Rating:Screening Version. Total ADHD symptom score consisted of 18 items (sum of inattention and hyperactivity-impulsivity subscales) using a 4-point scale (0=not at all/never to 3=very much/very frequently) for total score range of 0 to 54.

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

Conners' Adult Attention-Deficit Hyperactivity Disorder (ADHD) Rating Scale-Self Rating:Screening Version. Total ADHD symptom score consisted of 18 items (sum of inattention and hyperactivity-impulsivity subscales) using a 4-point scale (0=not at all/never to 3=very much/very frequently) for total score range of 0 to 54.

The 17-item HAMD measures depression severity. Each item was evaluated and scored using either a 5-point scale (e.g. absent, mild, moderate, severe, very severe) or a 3-point scale (e.g. absent, mild, marked). The total score of HAMD-17 may range from 0 (normal) to 52 (severe).

The HAMA-14 scale measures anxiety symptoms accompanying Major Depressive Disorder (MDD). Each item of the 14-item HAMA was scored from 0 (not present) to 4 (very severe), with a resulting maximum total score of 56.

This was a psychological test to observe the interference in which disparity between the meaning and color affects reading speed. A subject was given 3 tasks of recognition: reading the printed colored ink (Color Test), reading color words in black ink (Word Test), and interference, reading color words printed in different colored ink (Word-Color Test). The test was scored on the number of correct answers. There were 100 items for each of the three categories and if they made it through the 100 words with time remaining, they would repeat the list.

SF-36 assesses quality of life (QoL) on 8 domains and 2 summary scores (mental component summary [MCS] and physical component summary [PCS]). MCS and PCS scores=0-100 (higher scores indicate better QoL). Raw domain scores: general health=5-25; physical functioning=10-30; role-physical=4-20; role-emotional=3-15; social functioning=2-10; bodily pain=2-12; vitality=4-20; mental health=5-25. Using norm based scores, all domains, MCS and PCS scores have average score of 50 with standard deviation of 10. Norm-based score=Z-score*10+50 in each subscale. Range cannot be specified in norm-based scores.

Vital signs reported are Pulse (beats per minute [bpm]), Systolic Blood Pressure (SBP) (mmHg), and Diastolic Blood Pressure (DBP) (mmHg).

Potentially clinically significant weight loss was defined as any decrease of at least 7 percent (%). Potentially clinically significant weight gain was defined as any increase of at least 7%.

The Fridericia correction of the QT interval (QTcF) was used.

CYP2D6 is the primary atomoxetine metabolizing enzyme. Metabolizzer status was determined by focusing on the normal, decreased, and defective allele. Poor metabolizer = defective/defective. Extensive metabolizer is all except for poor metabolizer.
