Efficacy and Safety of Vortioxetine (Lu AA21004) in Treating Adults With Major Depressive Disorder

Takeda600 enrolled

Overview

The purpose of this study is to determine the efficacy and safety of once daily vortioxetine (Lu AA21004) in adults 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 vortioxetine. The study enrolled 600 patients. Participants were randomly assigned (by chance, like flipping a coin) to one of the two treatment groups-which remained undisclosed to the patient and study doctor during the study (unless there was an urgent medical need): * Vortioxetine 5 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-center trial was conducted in the United States. The overall time to participate in this study was approximately 94 days. Participants made 8 visits to the clinic, and were contacted by telephone 1 week, 2 weeks, and 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 6

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 range is from 0 to 74 where a higher score indicates a greater depressive state. Least squares (LS) means were from an Analysis of Covariance (ANCOVA) model with treatment and center as fixed factors and the baseline value as a covariate.

Time frame: Baseline and Week 6

Change From Baseline in the 24-item Hamilton Depression Scale Total Score at Other Weeks Assessed

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. LS means were from an ANCOVA model with treatment and center as fixed factors and the Baseline value as a covariate.

Time frame: Baseline and Weeks 1, 2, 3, 4 and 5

Secondary Outcomes

Percentage of Responders in HAM-D24 Total Score by Study Visit

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.

Time frame: Baseline and Weeks 1, 2, 3, 4, 5 and 6.

Percentage of Participants in MADRS Remission at Week 6

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.

Change From Baseline in Hamilton Anxiety Scale (HAM-A)

The 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 to 56, where \<17 indicates mild severity, 18-24 mild to moderate severity and 25-30 moderate to severe. Total scores above 30 are rare, but indicate very severe anxiety. Least squares means are from an ANCOVA model with treatment and center as fixed factors and the Baseline value as a covariate.

Time frame: Baseline and Weeks 1, 2, 4 and 6.

Change From Baseline in Clinical Global Impression Scale-Severity of Illness

The Clinical Global Impression - Severity scale (CGI-S) is a 7-point scale that requires the clinician to rate the severity of the patient'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 were from an ANCOVA model with treatment and center as fixed factors and the Baseline value as a covariate.

Time frame: Baseline and Weeks 1, 2, 3, 4, 5 and 6.

Clinical Global Impression Scale-Global Improvement Scale

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 were from an ANCOVA model with treatment and center as fixed factors and the CGI-S Baseline value as a covariate.

Time frame: Baseline and Weeks 1, 2, 3, 4, 5 and 6.

Change From Baseline in Montgomery-Åsberg Depression Rating Scale - Self-assessment (MADRS-S)

The MADRS-S is a patient-reported outcome measure based on MADRS, administered to evaluate treatment effectiveness in depression. This scale consists of 9 items assessing patients' mood, feelings of unease, sleep, appetite, ability to concentrate, initiative, emotional involvement, pessimism and zest for life. Each item is scored between 0 (best) and 3 (worst). The total score is calculated by summing the answers of the nine items, ranging between 0 and 27 (higher scores indicate increased impairment). LS means are from an ANCOVA model with treatment and center as fixed factors and the Baseline value as a covariate.

Time frame: Baseline and Weeks 1, 4 and 6.

Change From Baseline in 36-item Short-form Health Survey (SF-36) at Week 6

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 8 health concepts are: 1. Limitation in physical activities because of health problems. 2. Limitations in usual role activities because of physical health problems. 3. Bodily pain. 4. Limitations in social activities because of physical or emotional problems. 5. General mental health (psychological distress and well-being). 6. Limitations in usual role activities because of emotional problems. 7. Vitality (energy and fatigue). 8. General health perception. Each scale ranges from 0 (best) - 100 (worst). LS means are from an ANCOVA model with treatment and center as fixed factors and the Baseline value as a covariate.

Time frame: Baseline and Week 6

Change From Baseline in Sheehan Disability Scale (SDS) Total Score at Week 6

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 were from an ANCOVA model with treatment and center as fixed factors and the Baseline value as a covariate.

Time frame: Baseline and Week 6

Health Care Resource Utilization as Assessed by the Health Economic Assessment Questionnaire

Healthcare resource utilization was assessed by the Health Economic Assessment (HEA) questionnaire, which monitors the participants absenteeism from work, as well as resource use such as visits to a general practitioner, outpatient and inpatient services, hospitalization, medications, and other relevant services over the past 8 weeks.
