Mean Change From Baseline (End of Phase A) in the CAARS-O:SV ADHD Symptoms Total Score (18 Items) to End of Phase B |
The CAARS-O:SV is a 30 items scale with 3 subscales: Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) Inattentive Symptoms (9 items), DSM- IV Hyperactive/Impulsive Symptoms (9 items), and DSM-IV ADHD Index (12 items). Total ADHD Symptoms Score (18 items) consisted of the combined score for the inattentive symptoms and hyperactive/impulsive symptoms subscales and is scored on a 4-point scale from 0 (not at all; never) to 3 (very much, very frequently) for a total score ranging from of 0 to 54, higher scores indicate worsening of symptoms. A negative change from Baseline indicates improvement. The Mixed model repeated measures (MMRM) model was used for analysis. |

Change From Baseline (End of Phase A) in Wender-Reimherr Adult Attention Deficit Disorder Scale (WRAADDS) Total Score to End of Phase B |
WRAADDS is used to measure the severity of symptoms in adults with ADHD. This structured interview consists of 28 items in 7 psychopathologic domains, which were rated by a clinical expert on a 0 to 2-point Likert scale. The psychopathologic 7 domains are inattention (6 items), impulsivity (3 items), and hyperactivity (3 items), disorganization (5 items), temper (3 items), affective lability (4 items), and emotional over-reactivity (4 items). The scale rated individual items from 0 to 2 (0=not present, 1=mild, 2=clearly present) and summarized each of the 7 categories on a 0-to-4 scale (0=none, 1=mild, 2=moderate, 3=quite a bit, 4=very much). The WRAADDS total score is defined as sum of all 28 item sub scores (range 0 - 56), higher scores indicate worsening of symptoms. A negative change from Baseline indicates improvement. The analysis of covariance (ANCOVA) method was used for analysis. |

Change From Baseline (End of Phase A) in Sleep Improvement Measured by Insomnia Severity Index (ISI) Total Score to End of Phase B |
The ISI is self-report instrument that has been validated specifically for measuring the perceived severity of insomnia. The scale was composed of a total of 7 items based on self-report questionnaire based on several indicators assessing the perceived severity of difficulties initiating sleep, staying asleep, and early morning awakenings, satisfaction with current sleep pattern, interference with daily functioning, noticeability of impairment attributed to the sleep problem, and degree of distress or concern caused by the sleep problem. Each item was rated on a scale from 0 (none) to 4 (higher score indicating greater impairment/concern). A total score ranging from 0 to 28 was calculated from the sum of the individual item scores, higher scores indicate increased severity of insomnia. A negative change from Baseline indicates improvement. The MMRM model was used for analysis. |

Change From Baseline (End of Phase A) in the Spatial Working Memory (SWM) Between Errors 4-8 Boxes Test Score as Measured by Cambridge Neuropsychological Test Automated Battery (CANTAB) to End of Phase B |
ADHD was measured with the CANTAB. SWM test was one of the tasks of CANTAB, SWM measured the ability to retain spatial information and to manipulate remembered items in working memory. This test was sensitive measure of executive dysfunction. Participants search for colored tokens hidden inside boxes on screen by touching them. The critical instruction was that once token has been found inside box, no token was hidden inside that box again, so participants must not return to box where a token was found. The key measurement of the SWM task is the SWM Between Errors 4-8 Boxes, which measured the total number of times a participant revisits a box in which a token has previously been found is measured for the 4, 6, and 8-box stages. Total scores ranged from 0-153. A lower score indicated better performance. The ANCOVA model was used for analysis. |

The SWM test assesses the cognitive domain of executive function (high-level thinking and decision making). SWM task was SWM Strategy 6-8 Boxes, in which the total number of distinct boxes used by the participant to begin a new search for a token within the same problem was measured for the 6- and 8-box stages. The SWM strategy index of executive function represented the number of times a participant began a search with a different box. Participant was asked to find tokens in on-screen boxes and move them. Difficulty ranged from 4 to 8 box assessments. Strategy score was the number of unique boxes the participant searched in 6 and 8 box trials. 6 box trial scores ranged from 1 (1 box searched for all 6 tokens) to 6 (6 boxes searched for 6 tokens). 8 box trial score ranged from 1 (1 box searched) to 8 (8 boxes searched for 8 tokens). Total of the 2 trial scores ranged from 2 to 14. A lower score reflects better performance. The ANCOVA method was used for analysis. |

Change From Baseline (End of Phase A) in the Rapid Visual Information Processing (RVP) A Prime Test Score as Measured by CANTAB to End of Phase B |
Assessments were performed with the CANTAB. The RVP task tested continuous performance and visual sustained attention. In the center of the computer screen, digits from 2 to 9 appear inside a white box in pseudorandom order at a rate of 100 digits per minute. Participants must touch the press pad when they detect a series of target digit sequences (eg, 2-4-6, 4-6-8, 3-5-7) which appeared at a rate of 9 sequences every 100 numbers. Data from the RVP task were summarized in 3 ways: RVP A prime, RVP median response latency, and RVP total false alarms. RVP A prime was the signal detection measure of sensitivity to the target, regardless of response tendency (range 0.00 to 1.00; bad to good). In essence, this metric was a measure of how good the participant was at detecting target sequences. Higher scores indicated better performance. The ANCOVA method was used for analysis. |
