- Change From Baseline in Behavior Rating Inventory of Executive Function - Adult Version Global Executive Composite T-score (BRIEF-A GEC T) at Week 9, Last Observation Carried Forward (LOCF) [ Time Frame: Baseline and week 9 ]BRIEF-A Global Executive Composite assesses behavioral aspects of executive function. Items are rated 1 (never), 2 (sometimes), and 3 (often). There is no range for a total score. Raw scale scores are used to generate T-scores. A reduction in score indicates less impairment.
- Change From Baseline in Montgomery-Ǻsberg Depression Rating Scale (MADRS) Total Score at Week 9 - (LOCF) [ Time Frame: Baseline and week 9 ]MADRS is a validated, 10-item rating scale with each item being scored on a scale from 0-6 with a total score ranging from 0-60. Lower scores indicate a decreased severity of depression.
- Change From Baseline in BRIEF-A T-scores at Week 9, LOCF [ Time Frame: Baseline and week 9 ]BRIEF-A is a validated 75-item questionnaire. Items are rated 1 (never), 2 (sometimes), and 3 (often). There is no range for a total score. Raw scale scores are used to generate T-scores. A reduction in score indicates less impairment.
- Change From Baseline in Central Nervous System Vital Signs Computerized Cognitive Testing Battery Neurocognitive Domain and Index Scores at up to 9 Weeks/Endpoint [ Time Frame: Baseline and up to 9 weeks/Endpoint ]This measures the speed and accuracy of basic mental functions. Scores are normalized from raw scores and present an age matched score relative to other people in a normative sample. Scores are normalized with a mean of 100 and standard deviation of 15. Scores < 70 indicate likely deficit and impairment, and scores > 110 indicate high function and capacity. Higher scores are better.
- Percent of Participants With Clinical Global Impression - Severity of Illness (CGI-S) at Baseline [ Time Frame: Baseline ]CGI-S assesses the severity of the subject's condition on a 7-point scale ranging from 1 (normal, not at all ill) to 7 (among the most extremely ill)
- Percent of Participants With CGI-S at up to 9 Weeks/Endpoint [ Time Frame: Up to 9 weeks/Endpoint ]CGI-S assesses the severity of the subject's condition on a 7-point scale ranging from 1 (normal, not at all ill) to 7 (among the most extremely ill)
- Percentage of Participants With Improvement on Clinical Global Impression-Improvement (CGI-I) at Week 9, LOCF [ Time Frame: Week 9 ]Clinical Global Impression-Improvement (CGI-I) consists of a 7-point scale ranging from 1 (very much improved) to 7 (very much worse). Improvement is defined as a score of 1 (very much improved) or 2 (much improved) on the scale.
- Change From Baseline in Endicott Work Productivity Scale (EWPS) Total Score at up to 9 Weeks/Endpoint [ Time Frame: Baseline and up to 9 weeks/Endpoint ]The EWPS quantifies work performance, productivity attitudes and behaviors assessing 25 items on a scale ranging from 0 (high performance) to 4 (lowest performance). Scores range from 0 to 100 with 100 representing lowest productivity.
- Change From Baseline in Changes in Sexual Functioning Questionnaire (CSFQ-14) Total Scores for Males at Week 9, LOCF [ Time Frame: Baseline and week 9 ]This is a 14 item self-report tool that evaluates sexual functioning. Each item is scored on a 5-point Likert scale ranging from 1 (never) to 5 (always) with total scores ranging from 14 to 70. Higher scores reflect better sexual functioning.
- Change From Baseline in CSFQ-14 Total Scores for Females at Week 9, LOCF [ Time Frame: Baseline and week 9 ]This is a 14 item self-report tool that evaluates sexual functioning. Each item is scored on a 5-point Likert scale ranging from 1 (never) to 5 (always) with total scores ranging from 14 to 70. Higher scores reflect better sexual functioning.
- Change From Baseline in Short Form-12 Health Survey (SF-12) Scale Total Scores at Week 9 [ Time Frame: Baseline and week 9 ]The SF-12 is a 12-item self-report questionnaire that is a subset of the SF-36 Health Survey. The survey captures physical and mental health. Each of the 12 items is scored using various scales with a total score ranging from 0 (lowest level of health) to 100 (highest level of health).
- Change From Baseline in Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q) Total Scores at up to 9 Weeks/Endpoint [ Time Frame: Baseline and up to 9 weeks/Endpoint ]The Q-LES-Q is a 93-item self-report questionnaire on quality of life and health. Each item is rated on a 5-point scale from 1 (very poor) to 5 (very good) with a total score ranging from 93 to 465. Higher scores indicate greater satisfaction.
- Change From Baseline in Amphetamine Cessation Symptom Assessment (ACSA) Total Score at Week 11 [ Time Frame: Baseline and week 11 ]ACSA scale has 16 symptom items rated on a scale from 0 (not at all) to 4 (extremely) with a possible total score range of 0 to 64. Higher scores indicate greater withdrawal symptom severity.
- Change From Baseline in the Generalized Anxiety Disorder 7-Item (GAD-7) Total Score at Week 9, LOCF [ Time Frame: Baseline and week 9 ]The GAD-7 is a 7-item self-report questionnaire for assessing anxiety severity. Each item is scored using a scale that ranges from 0 (not at all) to 3 (nearly every day) with total scores ranging from 0 to 21. Lower scores indicate a reduction in anxiety.
- Change From Baseline in Sheehan Suicidality Tracking Scale (STS) Total Score at Week 9 [ Time Frame: Baseline and week 9 ]The STS is an 8-question clinician-rated assessment of suicidal ideation, suicidal behavior, and accidents. The items are scored on a 5-point Likert scale from 0 (not at all) to 4 (extremely) and summed to produce a total score ranging from 0 to 32. Lower scores indicate reduced suicidal tendencies.
