About this study

The study employed the Sequential Parallel Comparison Design (SPCD), a clinical study design which intend to increase signal detection by using two stages of treatment:

  • Stage 1 - first 6 weeks of the 12-weeks treatment period (Visit 2/Baseline 1 to Visit 5/Week 6)
  • Stage 2 - last 6 weeks of the 12-weeks treatment period (Visit 5/Baseline 2 to Visit 8/Week 12)

In Stage 1, patients were randomized to placebo or vortioxetine 10 or 20mg. Patients on vortioxetine 10 or 20mg/day during Stage 1 remained on the same treatment in Stage 2. Responders to placebo in Stage 1 remained on Placebo in Stage 2. Patients who were placebo non-responders during Stage 1, defined as patients with a <30% reduction in AISRS total score from Baseline 1, were re-randomized to placebo or vortioxetine 10 or 20mg/day in Stage 2.

Primary outcomes

  1. Change in ADHD Investigator Symptom Rating Scale (AISRS) Total Score

    Time frame: Baseline to Week 6

    AISRS: an 18-item scale administered by the investigator. It included 9 items that evaluated symptoms of inattention and 9 items that evaluated symptoms of impulsivity and hyperactivity. Each item was rated from 0 (none) to 3 (severe). AISRS total score was calculated as sum of all the items on the scale and ranged from 0 to 54. A higher score corresponded to a worse severity of ADHD.

Secondary outcomes

  1. Inattention/Meta-cognition: Change in Behavior Rating Inventory of Executive Function - Adult Version (BRIEF-A) Using Metacognition Index

    Time frame: Baseline to Week 6

    The Metacognition Index (MI) is an index score of the BRIEF-A consisting of 5 scales: initiate, working memory, plan/organise, task monitor, and organization of materials. Each item is rated on a 3-point scale with the numeric score of 1 to 3. Raw scale scores are used to generate T-scores. A reduction in score indicates less impairment.

  2. Cognitive Function/Global Executive Function: Change in BRIEF-A Using the Global Executive Composite Score

    Time frame: Baseline to Week 6

    BRIEF-A is a validated questionnaire composed of 75-item within nine non-overlapping scales: 4 scales in the Behavioral Regulation Index (BRI) (inhibit, shift, emotional control, and self-monitor), and 5 scales in the Metacognition Index (MI) (initiate, working memory, plan/organise, task monitor, and organization of materials). Each item is rated on a 3-point scale with the numeric score of 1 to 3. The BRIEF-A yields an overall score (Global Executive Composite) composed of two index scores, the MI and the BRI. Raw scale scores are used to generate T-scores. A reduction in score indicates less impairment.

  3. Overall Functioning: Change in Sheehan Disability Scale (SDS) Total Score

    Time frame: Baseline to Week 6

    The SDS comprises a series of patient rated scales designed to measure impairment. The patient rates the extent to which his or her (1) work, (2) social life or leisure activities and 3) home life or family responsibilities are impaired on a 10-point visual analogue scale, on which 0 = normal functioning and 10 = severe functional impairment. The number of days lost and the number of underproductive days last from work/school due to symptoms are also captured. The total score is calculated as a sum of the 3 visual analogue scales, ranges from 0 to 30. A higher score represents more severe functional impairment. A reduction in score indicates less impairment.

  4. Productivity: Change in Work Limitations Questionnaire (WLQ) Productivity Loss Score

    Time frame: Baseline to Week 6

    The WLQ is a patient self-rated scale designed to assess on-the-job impact of chronic health problems and/or treatment. The WLQ consists of 25 items in 4 dimensions: limitations handling time (5 items), physical work demands (6 items), mental-interpersonal work demands (9 items), and output demands (5 items). Each item is rated on a 5-point scale from "All of the Time" (score 5) to "None of the Time" (score 0), or "Does Not Apply to My Job". The WLQ Productivity Loss Score is derived from the Global Productivity Index, which is calculated as a weighed sum of the 4 dimensions. Reduction in WLQ Productivity Loss score indicates less work limitation and represents the estimated percentage of productivity loss in the past two weeks due to presenteeism relative to a healthy benchmark sample. WLQ Productivity Loss Score ranges from 0% to 24,9%.

  5. Change in AISRS Inattention Sub-score
