Efficacy Study of Vortioxetine (Lu AA21004) in Adults With Major Depressive Disorder

The Sheehan Disability Scale assesses functional impairment in 3 domains: work/school, social life or leisure activities, and home life or family responsibilities. The participant rates the extent to which each aspect is impaired on a 10-point visual analog scale, from 0 (not at all) to 10 (extremely). The 3 scores are added together to calculate the total score, which ranges from 0 to 30, with higher scores indicating more impairment. LS means are from a mixed model for repeated measurements (MMRM) with Baseline-by-week, center, week, and week-by-treatment as factors in the analysis.

The Clinical Global Impression - Global Improvement scale assesses the participant's improvement (or worsening) as assessed by the clinician relative to Baseline on a 7-point scale: 1, very much improved; 2, much improved; 3, minimally improved; 4, no change; 5, minimally worse; 6, much worse; or 7, very much worse. LS means are from a mixed model for repeated measurements (MMRM) with Baseline-by-week, center, week, and week-by-treatment as factors in the analysis.

A responder is defined as a participant with a ≥50% decrease from Baseline in HAM-D24 total score. The HAM-D24 is a clinician-rated 24-item scale for assessing the severity of depression symptoms. The scores for each item range from 0 to 4 or 0 to 2, where 0 represents no symptoms. The rating is based on the past 7 days prior to the time of assessment. The total score ranges from 0 to 74, where a higher score indicates a greater depressive state.

The rating is based on the past 7 days prior to the time of assessment. The total score ranges from 0 to 74 where a higher score indicates a greater depressive state. The Hamilton Anxiety Scale (HAM-A) is an anxiety rating scale consisting of 14 items that assess anxious mood, tension, fear, insomnia, intellectual (cognitive) symptoms, depressed mood, behavior at interview, somatic (sensory), cardiovascular, respiratory, gastrointestinal, genitourinary, autonomic and somatic (muscular) symptoms. Each symptom is rated from 0 (absent) to 4 (maximum severity). Total scores range from 0 (symptoms absent) to 56 (severe symptoms). LS means are from a mixed model for repeated measurements (MMRM) with Baseline-by-week, center, week, and week-by-treatment as factors in the analysis.

Remission is defined as a participant with a Montgomery Åsberg Depression Rating Scale (MADRS) total score ≤10. The MADRS is a depression rating scale consisting of 10 items, each rated 0 to 6. The 10 items represent the core symptoms of depressive illness. The overall score ranges from 0 (symptoms absent) to 60 (severe depression). Decrease in the total score or on individual items indicates improvement.

The Clinical Global Impression - Severity scale (CGI-S) is a 7-point scale that requires the clinician to rate the severity of the participant's illness at the time of assessment, relative to the clinician's past experience with patients who have the same diagnosis. Considering total clinical experience, a patient is assessed on severity of mental illness on the following scale: 1, normal, not at all ill; 2, borderline mentally ill; 3, mildly ill; 4, moderately ill; 5, markedly ill; 6, severely ill; or 7, extremely ill. LS means are from a mixed model for repeated measurements (MMRM) with Baseline-by-week, center, week, and week-by-treatment as factors in the analysis.

The HAD scale is completed by the participant and comprises two subscales, one measuring depression (focusing on the state of lost interest and diminished pleasure response) and one measuring anxiety (including anxious mood, restlessness, anxious thoughts, panic attacks). Each subscale is made up of 7 items that are assessed on a scale of 0 = no anxiety/depression to 3 = severe feeling of anxiety/depression. Participants are required to indicate the response which most accurately reflects the way they have felt over the last few days. Scores for the depression and anxiety subscales are summed separately and not combined, with each score ranging from 0 to 21 (maximal severity). LS means are from a mixed model for repeated measurements (MMRM) with Baseline-by-week, center, week, and week-by-treatment as factors in the analysis
