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

Takeda560 enrolled

Overview

The purpose of this study is to determine the effectiveness and safety of vortioxetine, once daily (QD), in patients with Major Depressive Disorder.

The drug that was tested in this study is called vortioxetine. Vortioxetine is being tested to treat depression in adults who have major depressive disorder (MDD). This study looked at MDD relief in people who took varying dosages of vortioxetine. The study enrolled 560 patients. Participants were randomly assigned (by chance, like flipping a coin) to one of the four treatment groups-which remained undisclosed to the patient and study doctor during the study (unless there was an urgent medical need): * Vortioxetine 1 mg * Vortioxetine 5 mg * Vortioxetine 10 mg * Placebo (dummy inactive pill) - this was a capsule that looked like the study drug but had no active ingredient. All participants were asked to take one capsule at the same time each day throughout the study. This multi-centre trial was conducted in Europe, Asia, Australia, and South Africa. The overall time to participate in this study was up to 14 weeks. Participants made 7 visits to the clinic, and were contacted by telephone 4 weeks after the last dose of study drug for a follow-up assessment.

Outcomes

Primary Outcomes

Change From Baseline in the 24-item Hamilton Depression Scale Total Score At Week 8

The 24-item Hamilton Depression Scale (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 range is from 0 to 74 where a higher score indicates a greater depressive state. Least squares (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.

Time frame: Baseline to Week 8

Secondary Outcomes

Change From Baseline in Sheehan Disability Scale (SDS) Total Score at Week 8

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.

Time frame: Baseline to Week 8

Clinical Global Impression Scale-Global Improvement at Week 8

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.

Change From Baseline in Clinical Global Impression Scale-Severity of Illness at Each Week Assessed

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.

Change From Baseline in Hospital Anxiety and Depression (HAD) Scales at Each Week Assessed

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

Change From Baseline in 36-Item Short-Form Health Survey (SF-36) Physical Functioning Subscore at All Weeks Assessed

The Medical Outcomes Study SF-36 is a participant self-rated questionnaire that is a general measure of perceived health status comprising 36 questions, which yields an 8-scale health profile. The physical functioning subscale assesses limitations in physical activities because of health problems. The sub-score scale ranges from 0 (best) - 100 (worst). 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.
