A Study in Adult Patients With Major Depressive Disorder

The MADRS measured severity of depressive mood symptoms. The 10-item checklist rating scale was 0 to 6, for a total score range of 0 (low severity of depressive symptoms) to 60 (high severity of depressive symptoms). Least Squares (LS) Means were adjusted for investigator, visit, baseline score, and baseline-by-visit.

The SDS was completed by the participant and used to assess the effect of the participant's symptoms on their work/social/family life. Total of these 3 items=Global Functional Impairment score; scores ranged from 0 to 30, with higher values indicating greater disruption in the participant's work/social/family life. Least Squares (LS) Means were adjusted for treatment, investigator, visit, treatment-by-visit, baseline score, and baseline-by-visit.

CGI-S measured severity of depression at the time of assessment. Scores ranged from 1 (normal, not at all ill) to 7 (among the most extremely ill participants). Least Squares (LS) Means were adjusted for treatment, investigator, visit, treatment-by-visit, baseline score, and baseline-by-visit.

The QIDS-SR16 was a 16-item participant-rated measure of depressive symptomatology. The total score ranged from 0 to 27, with higher scores indicative of greater severity. Least Squares (LS) Means were adjusted for treatment, investigator, visit, treatment-by-visit, baseline score, and baseline-by-visit.

The CPFQ was a 7-item participant-rated questionnaire pertaining to a participant's cognitive and physical well-being. It assessed motivation, wakefulness, energy, focus, recall, word-finding difficulty, and mental acuity. Each item was scored on a 6-point scale ranging from 1 (greater than normal) to 6 (totally absent); total score ranged from 7 to 42. Least Squares (LS) Means were adjusted for treatment, investigator, and baseline score.

EQ-5D was a generic, multidimensional, health-related, quality of life (Qol) instrument allowing participants to rate their health state in 5 domains: mobility, self-care, usual activities, pain/discomfort, and mood. A single score between 1 and 3 was generated for each domain. For each participant, the outcome rating on the 5 domains was mapped to a single index through an algorithm. The index ranged between 0 and 1, with the higher score indicating a better health state perceived by the participant. Least Squares (LS) Means were adjusted for treatment, investigator, and baseline score.

The FAsD was a participant-rated scale with 7 items that asked how often they experience different aspects of fatigue: responses from 1 (Never) to 5 (Always); 9 items that asked how often fatigue impacts various aspects of their lives: responses from 1 (Not at all) to 5 (Very much). Average Score=mean of Items 1-5, 7-12, 14, and 16. Scores ranged from 1 to 5. Least Squares (LS) Means were adjusted for treatment, investigator, visit, treatment-by-visit, baseline score, and baseline-by-visit.

The BFI was a participant-rated scale consisting of 9 items: 3 items assessed severity of fatigue at its "worst," "usual," and "now" during normal waking hours: 0=no fatigue to 10=fatigue as bad as you can imagine; 6 items assessed the degree to which fatigue has interfered with different aspects of the participant's life during the past 24 hours: 0=does not interfere to 10=completely interferes. The BFI Global Total Score was the mean of the 9 item scores and ranged from 0 to 10. Least Squares (LS) Means were adjusted for treatment, investigator, and baseline score.

The VAS-F was a self-rated assessment with 2 items. For the Overall Severity of Fatigue item, the participant placed a vertical mark on a 100-millimeter (mm) line between 2 anchors (0=not at all to 100=as severe as I can imagine). For the Interference With Daily Activities Due to Fatigue item, the participant placed a vertical mark on a 100 mm line between 2 anchors (0=not at all to 100=complete disability [unable to do any activities]). Least Squares (LS) Means were adjusted for treatment, investigator, visit, treatment-by-visit, baseline score, and baseline-by-visit.

The Resource Utilization form assessed the frequency and type of medical services that participants have used within the last year, or since the last visit. Resources reported by at least 5% of participants in either treatment group were provided.

C-SSRS scale captured occurrence, severity, and frequency of suicide-related thoughts and behaviors. Number of participants with suicidal ideation, behavior, and acts were provided. Suicidal ideation=a "yes" answer to any 1 of 5 suicidal ideation questions (including wish to be dead) and 4 different categories of active suicidal ideation. Suicidal behavior=a "yes" answer to any of 5 suicidal behavior questions: preparatory acts or behavior, aborted attempt, interrupted attempt, actual attempt, and completed suicide. Suicidal act=a "yes" answer to actual attempt or completed suicide.
