Primary Outcome Measures

Name	Time	Method
Change From Baseline in Attention-Deficit/Hyperactivity Disorder Rating Scale (ADHDRS) Total Score - Parent Version at Week 16 Endpoint	Baseline, 16 weeks	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 0-54. Least Square mean of change from baseline in ADHDRS is from a restricted maximum likelihood-based, mixed model repeated measures analysis which includes the effects of treatment, investigative site, baseline, visit, treatment-by-visit interaction, and baseline-by-visit interaction.

Secondary Outcome Measures

Name	Time	Method
Change From Baseline in Attention-Deficit/Hyperactivity Disorder Rating Scale (ADHDRS) Total and Subscores - Parent Version at Week 16 Endpoint	Baseline, 16 weeks	The ADHDRS-IV-Parent is an 18-item scale with 1 item for each of the 18 symptoms contained in the DSM-IV diagnosis of ADHD. Each item is scored on a 0 to 3 scale: 0=none (never or rarely); 1=mild (sometimes); 2=moderate (often); 3=severe (very often). Hyperactivity-impulsivity scores range 0-27, and inattention scores range 0-27. Total scores range from 0-54. Higher scores indicate higher impairment.
Change From Baseline in Attention-Deficit/Hyperactivity Disorder Rating Scale (ADHDRS) Total and Subscores - Teacher Version at Week 16 Endpoint	Baseline, 16 weeks	The ADHDRS-IV-Teacher is an 18-item scale with 1 item for each of the 18 symptoms contained in the DSM-IV diagnosis of ADHD. Each item is scored on a 0 to 3 scale: 0=none (never or rarely); 1=mild (sometimes); 2=moderate (often); 3=severe (very often). Hyperactivity-impulsivity scores range from 0-27, and inattention scores range from 0-27. Total scores range from 0-54. Higher scores indicate higher impairment.
Change From Baseline in Woodcock-Johnson III Scores at Week 16 Endpoint	Baseline, 16 weeks	The Woodcock Johnson Tests of Achievement has a Standard Battery (Tests 1-12) of a broad set of scores and an Extended Battery (Tests 13-22) on specific academic strengths and weaknesses. Tests associated with reading skills (1, 2, 7, 9, 13, 17, 20) were administered. Scores for each individual test can range from 0 to over 200 where anything 69 and below is very low and anything 131 and above is very superior. Higher scores indicate better reading skills.
Change From Baseline in Comprehensive Test of Phonological Processing (CTOPP) at Week 16 Endpoint	Baseline, 16 weeks	The CTOPP assesses phonological awareness, phonological memory, and rapid naming and is appropriate for ages 7 to 24. The test contains six core subtests. The composite scores are 1) Phonological Awareness, comprised of the standard scores of the Elision and Blending Words; 2) Phonological Memory, comprised of standard scores for Memory for Digits and Non-word Repetition; and 3) Rapid Naming, comprised of standard scores for Rapid Digit Naming and Rapid Letter Naming. Standard scores range from 1-20, and composite scores range from 35-165. Higher scores are better.
Change From Baseline in Gray Oral Reading Test-4 (GORT-4) at Week 16 Endpoint	Baseline, 16 weeks	The GORT-4 is a norm-referenced test of oral reading rate, accuracy, fluency, and comprehension valid for individuals aged 6 to 18 years old. The test has two parallel forms, Form A and Form B, that are administered in an alternating fashion (e.g. Week 0-Form A, Week 16-Form B, Week 32-Form A.) with each containing 14 separate stories and 5 multiple-choice comprehension questions for each story. GORT-4 yields the following scores: rate, accuracy, fluency, comprehension, and overall reading ability. Standard scores range from 1-20. Higher scores indicate better reading skills.
Change From Baseline in Test of Word Reading Efficiency (TOWRE) at Week 16 Endpoint	Baseline, 16 weeks	The TOWRE is a measure of an individual's ability to pronounce printed words accurately and fluently and is appropriate for individuals aged 6 to 24 years old. The TOWRE contains two subtests: Sight Word Efficiency (SWE) which assesses the number of real printed words that can be accurately identified within 45 seconds and Phonemic Decoding Efficiency (PDE) which measures the number of pronounceable printed non-words that can be accurately decoded within 45 seconds. Scores range from 45-146. Higher scores indicate higher reading proficiency.
Change From Baseline in Working Memory Test Battery for Children (WMTB-C) at Week 16 Endpoint	Baseline, 16 weeks	WMTB-C is assessment of working memory capacities, consisting of 9 subtests (Trials Correct Scores \[Range from 55-145\], Higher scores are better) reflecting 3 main components of working memory: central executive (CE) control/regulation of working memory (Backward Digit Recall, Listening Recall, Counting Recall); phonological loop (PL) responsible for holding verbal information for short periods (Digit Recall, Word List Matching, Word List Recall, Non-word List Recall); and visuo-spatial sketchpad (VSSP) which holds information in visual and spatial form (Block Recall, Mazes Memory).

This scale measures improvements in social, emotional, cognitive, educational, and affiliative (family, friends) functioning, which indirectly reflect improvements in executive functioning. Happy/social subscores range from 0-18, and self-control subscores range from 0-54. Total scores range from 0-72. Higher scores are better for LPS.
Change From Baseline in Kiddie Sluggish Cognitive Tempo (K-SCT) at Week 16 Endpoint	Baseline, 16 weeks	The K-SCT rating scale contains 3 components: Youth, Parent, and Teacher ratings. It queries 17 candidate SCT symptoms, such as daydreams, lost in a fog, sluggish/drowsy. Scores range from 0-51. Lower scores indicate less sluggish.
Change From Baseline in Multidimensional Self Concept Scale (MSCS) at Week 16 Endpoint	Baseline, 16 weeks	The MSCS is an overall assessment of self concept or an individual measure of any of the six scaled dimensions of self concept: Social, Competence, Affect, Academic, Family, and Physical. Standard scores range from 45-145. Higher scores are better (indicate higher self concept).
