About this study
Official title: A Phase 3, Randomized, Double-Blind, Parallel-Group, Placebo-Controlled, Duloxetine-Referenced, Fixed-Dose Study Comparing the Efficacy and Safety of 2 Doses (15 and 20 mg) of Lu AA21004 in Acute Treatment of Adults With Major Depressive Disorder
The purpose of this study is to evaluate the efficacy, safety and tolerability of vortioxetine, once daily (QD), compared with placebo in adults with major depressive disorder.
Read the detailed description
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 614 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 15 mg
- Vortioxetine 20 mg
- Duloxetine 60 mg
- Placebo (dummy inactive capsule) - 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 up to 13 weeks. Participants made 9 visits to the clinic, and were contacted by telephone 4 weeks after the last dose of study drug for a follow-up assessment.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change From Baseline in the Montgomery-Åsberg Depression Rating Scale (MADRS) Total Score
The MADRS is a depression rating scale consisting of 10 items, each rated 0 (normal) to 6 (most abnormal). The 10 items represent the core symptoms of depressive illness. The overall score ranges from 0 (symptoms absent) to 60 (severe depression). A decrease in the total score or on individual items indicates improvement. Least squares (LS) means are from a mixed model for repeated measurements (MMRM) analysis of covariance (ANCOVA) with treatment, center, week, treatment-by-week interaction, Baseline MADRS total score-by-week as fixed effects.
Measured: Baseline and Week 8
Secondary outcomes (5)
Percentage of Participants With a MADRS Response at Week 8
Response is defined as a participant with a ≥50% decrease in Montgomery Åsberg Depression Rating Scale (MADRS) total score from Baseline. 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.
Measured: Baseline and Week 8
Mean Clinical Global Impression Scale - Improvement (CGI-I) Score 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 were from a mixed model for repeated measurements (MMRM) ANCOVA with treatment, center, week, treatment-by-week interaction, Baseline Clinical Global Impression Scale-Severity of Illness (CGI-S) score-by-week as fixed effects.
Measured: Week 8
Change From Baseline in MADRS Total Score at Week 8 in Participants With Baseline Hamilton Anxiety Scale (HAM-A) Total Score ≥20
The MADRS is a depression rating scale consisting of 10 items, each rated 0 (normal) to 6 (most abnormal). The 10 items represent the core symptoms of depressive illness. The overall score ranges from 0 (symptoms absent) to 60 (severe depression). A decrease in the total score or on individual items indicates improvement. LS means are from a mixed model for repeated measurements (MMRM) ANCOVA with treatment, center, week, treatment-by-week interaction, Baseline MADRS total score-by-week as fixed effects.
HAM-A is a 14 item rating scale to quantify anxiety severity rated on a 5-point scale from 0 (not present) to 4 (severe) with a total score range from 0 to 56, where lower scores indicate mild severity.
Measured: Baseline and Week 8
Percentage of Participants in MADRS Remission at Week 8
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.
Measured: Week 8
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 were from mixed model for repeated measurements (MMRM) ANCOVA with treatment, center, week, treatment-by-week interaction, Baseline SDS total score-by-week as fixed effects.
Measured: Baseline and Week 8

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Vortioxetine and Duloxetine in people with Depressive Disorder, Major, run by Takeda at 56 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 18 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 18 Dec 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 56 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 18 Dec 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change From Baseline in the Montgomery-Åsberg Depression Rating Scale (MADRS) Total Score (time frame: Baseline and Week 8). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01153009, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Dec 2013.
