Primary Outcome Measures :
  1. The Incidence of Overall Adverse Events, AEs , Serious Adverse Envents,(or SAEs), and AEs (or SAEs) Leading to Discontinuation [ Time Frame: 26 Weeks ]
    Overall adverse events, AEs , serious adverse envents,(or SAEs), and AEs (or SAEs) leading to discontinuation.

Secondary Outcome Measures :
  1. Change From Baseline, in Attention Deficit Hyperactivity Disorder Rating Scale, Version IV, Home Version, (ADHD RS IV HV) Total Score. [ Time Frame: 26 Weeks ]

    The ADHD RS-IV HV is a validated scale that consists of 18 items designed to reflect current symptomatology of ADHD based on Diagnostic and Statistical Manual for Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) criteria and is also consistent with DSM-5 criteria.

    Each item is scored from a range of zero (reflecting no symptoms) to 3 (reflecting severe symptoms) with total scores ranging from zero to 54. The 18 items may be grouped into 2 subscales: hyperactivity/impulsivity (even number items 2 through 18) and inattentiveness (odd number items 1 through 17).

  2. Change From Baseline, in Clinical Global Impression-Severity of Illness (CGI S) Score. [ Time Frame: 26 weeks ]
    The CGI-S scale, modified captures the clinician's rating of observed and reported ADHD symptoms, behavior, and function over the past 7 days. The CGI-S is rated on the following 7-point scale: 1 = normal, not at all ill; 2 = borderline mentally ill; 3 = mildly ill; 4 = moderately ill; 5 = markedly ill; 6 = severely ill; and 7 = among the most extremely ill subjects.
