Intervention / Treatment

Intervention / Treatment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

2 years to 8 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Male and female subjects aged 6-12 years, inclusive.
  • Subjects meeting the DSM-IV criteria for ADHD of any type, 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 (Concerta® 36 mg and 54 mg is allowable)

Exclusion Criteria:

  • Parent or guardian unable or unwilling to complete the Conner's ADHD/DSM-IV Scale for Parents (CADS-P) and the Daily Diary Card
  • Diagnosed with 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, AST, GGPT or serum creatinine greater then 2X the ULN 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) are excluded
  • 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

Other protocol defined inclusion/exclusion criteria may apply

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change From Pre-dose (0 hr [Hour]) on the Swanson, Kotkin, Agler, M-Flynn & Pelham (SKAMP) Rating Scale Combined Score at 0.5 Hour During the 8- Hour Laboratory Classroom Day
Time Frame: 0 hr and 0.5 hr post-dose
SKAMP rating scale is comprised of 13 questions (7 questions on attention and 6 questions on deportment) evaluating classroom behavior; answers to each question range from 0 (normal, no impairment) to 6 (maximum impairment) for a total possible combined score of 0 to 78.
0 hr and 0.5 hr post-dose

Secondary Outcome Measures
