Primary Outcome Measures:
  • Adult ADHD Investigator Symptom Rating Scale (AISRS) [ Time Frame: 6 weeks ]
    The Adult ADHD Investigator Symptom Rating Scale (AISRS) is a modified version of the ADHD Rating Scale that more accurately reflects the impact and severity of ADHD among adults. It is a clinician-administered scale that measures all 18 symptoms of adult ADHD using a Likert scale (from 0 [not present] to 3 [severe]). The total ranges from 0 to 54.

Secondary Outcome Measures:
  • Barkley Deficits in Executive Functioning Scale-short form: self report (BDEFS-SF:Self-Report) [ Time Frame: 6 weeks ]
    The Barkley Deficits in Executive Functioning Scale-short form: self report (BDEFS-SF:Self-Report) is an empirically based tool for evaluating dimensions of adult executive functioning in daily life. The BDEFS-SF offers an ecologically valid snapshot of the capacities involved in time management; organization and problem solving; self restraint; self motivation; and self-regulation of emotions. The total score on the BDEFS-SF range from 0 to 80.

Ages Eligible for Study:   18 Years to 45 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Subjects must meet the following ADHD diagnostic and inclusion criteria:
  • Subjects must meet Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) criteria for current ADHD subtypes (ADHD combined type, ADHD predominately inattentive type, ADHD predominately hyperactive-impulsive type) as assessed by the clinical interview and confirmed by Adult Attention-Deficit/Hyperactivity Disorder Clinical Diagnostic Scale (ACDS V1.2).
  • Subjects must have a total score of 24 or greater on the AISRS at both the Screening and Baseline Visits AND the Baseline Visit AISRS scores must not vary by more than 20% from Screening.
  • Subjects are required to have CGI-S score ≥4 (moderate) at both the Screening and Baseline Visits. Subjects should have at least moderate severity for ADHD symptoms.
  • For women of childbearing potential, documentation of a negative serum pregnancy test at Screening and a negative urine pregnancy test on Day 0. All female subjects of childbearing potential must be using a highly effective method of birth control during the study and for at least 1 month after completion of study drug dosing.
  • A highly effective method of birth control is defined as one that results in a low failure rate (i.e., <1% per year) when used consistently and correctly, such as condom + diaphragm, condom + spermicide, diaphragm + spermicide, or intrauterine device [IUD] with documented failure rate of <1% per year, or oral/injectable/implanted hormonal contraceptives used in combination with a barrier method.
  • Women are considered to be not of childbearing potential if they have had a total hysterectomy or bilateral tubal ligation (documentation for either must be provided before enrollment) or are at least 2 years postmenopausal. Female subjects cannot be breast-feeding.

Exclusion Criteria:

Any current psychiatric disorder other than ADHD as defined in DSM-IV-TR as assessed by Mini International Neuropsychiatric Interview (MINI). Subjects with dysthymia that does not require pharmacological treatment will not be excluded.

  • MADRS total score >15.
  • A diagnosis of ADHD NOS.
  • Any diagnosis of lifetime bipolar disorder or psychotic disorder
  • A current diagnosis of any severe comorbid Axis II disorder
  • Any history of mental retardation, organic mental disorders due to general medical condition or pervasive developmental disorder as defined by DSM-IV-TR.-
