Outcome Measures
Primary Outcomes (1)
Change From Pre-dose in the Swanson, Kotkin, Agler, M Flynn, and Pelham (SKAMP) Combined Attention and Deportment Scores at 10, 11, and 12 Hour (Averaged) Post-dose
SKAMP is a 13-item rating scale that measures classroom manifestations of ADHD consisting of 2 subscales (7 items for Attention and 6 items for Deportment) used to generate a score at Hours 10, 11 and 12 on Day 7 of Weeks 1, 2 and 3. The ratings were based on both frequency and quality of specific behaviors. The rating scale is 0 (normal, no impairment) to 6 (maximum impairment) for a total possible combined score of 0 to 78. The reported measure is the difference from baseline of the 2 combined subscores averaged over Hours 10, 11 and 12. A negative score indicates improvement.
Pre-dose to 10, 11, and 12 hours post-dose
Secondary Outcomes (4)

Pre-dose to 10, 11, and 12 hours post-dose
Change From Pre-dose in the Swanson, Kotkin, Agler, M Flynn, and Pelham (SKAMP) Deportment Score at 10, 11, and 12 Hour (Averaged) Post-dose
Pre-dose to 10, 11, and 12 hours post-dose
Change From Pre-dose in the Permanent Product Measure of Performance of Measurement (PERMP) Math Test-Attempted Score at 10, 11, and 12 Hours (Averaged) Post-dose
Pre-dose to 10, 11, and 12 hours post-dose

Eligibility Criteria
You may qualify if:
- Male and female subjects aged 6-12 years, inclusive.
- Subjects meeting the DSM-IV criteria for primary diagnosis of ADHD-Combined type, or predominantly hyperactive-impulsive subtype, as established by the K-SADS-PL (Kiddie Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version). If a DSM-IV-defined ADHD diagnosis is difficult to establish due to possible co-morbidity, the subject will not be enrolled into the study.
- Subjects should be on a stabilized total daily dose or nearest equivalent of 40-60 mg methylphenidate or 20-30 mg of d-methylphenidate for at least two weeks prior to Screening visit.
You may not qualify if:
- Subject or subject's guardian unable to understand or follow instructions necessary to participate in the study.
- Diagnosed with or history of a tic disorder or Tourette's syndrome.
- History of seizure disorder.
- The presence of a known medical condition that would preclude the use of methylphenidate.
- A history (within the past year) or presence of clinically significant cardiovascular, cerebrovascular, renal, hepatic, gastrointestinal, pulmonary, immunological, hematological, endocrine, or neurological disease.
- ALT (Alanine Amino Transferase), AST (Aspartate Amino Transferase), GGT (Gamma glutamyl transferase) or serum creatinine greater then 2X the ULN (Upper Limit of Normal) at Screening.
- A history of psychiatric illness or substance use disorder (e.g., schizophrenia, bipolar disorder, autism, abuse or dependence, depression, severe Conduct Disorder or severe Oppositional defiant disorder)
- Subjects who have participated in an investigational trial within the past 4 weeks (28 days)
- Subjects who are currently taking antidepressants or other psychotropic medication.
- Subjects who have initiated psychotherapy during the three months prior to randomization.
- Subjects with a positive urine drug screen.
- Subjects who have a history of poor response or intolerance to methylphenidate or d-methylphenidate.
