About this study
Official title: A Long-Term, Open-Label, Flexible-Dose, Extension Study Evaluating the Safety and Tolerability of Lu AA21004 in Subjects With Major Depressive Disorder
The purpose of this study is to determine the long-term efficacy and safety of vortioxetine, once daily (QD), 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 people who have major depressive disorder (MDD). This study looked at MDD relief in people who took vortioxetine.
The study enrolled 836 patients that had completed one of two other vortioxetine studies. Participants received 5 mg of vortioxetine for the first week of treatment. After completing the first week of treatment, the dose could be increased to 10 mg/day or decreased to 2.5 mg/day based on participant's response as judged by the doctor.
All participants were asked to take one encapsulated tablet at the same time each day throughout the study.
This multi-center trial was conducted worldwide. The overall time to participate in this study was up to 56 weeks. Participants made 13 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.
Physical Examination Findings
Physical examination consisted of the following body systems: (1) appearance; (2) extremities; (3) skin; (4) head and neck; (5) eyes, ears, nose, and throat; (6) lungs and chest; (7) heart and cardiovascular system; (8) abdomen; and (9) musculoskeletal system. An assessment of the nervous system was conducted; any findings were captured under the appropriate body area.
Each system was assessed as normal or abnormal.
Measured: Baseline and Week 52
Number of Participants With Potentially Clinically Significant Laboratory Evaluation Findings
Participants with at least one post-baseline potentially clinically significant (as defined in the table below) serum chemistry, hematology or urinalysis result. ULN = upper limit of normal; LLN = Lower limit of normal.
Measured: Weeks 4, 8, 12, 20, 28, 36, 44 and 52
Number of Participants With Potentially Clinically Significant Electrocardiogram (ECG) Findings
A standard 12-lead ECG was performed at the designated study visits. The central reader reviewed and recorded the intervals (PR, QRS, RR, QT, and corrected QT interval [QTc]), and interpreted the ECG using 1 of the following categories: within normal limits or abnormal. The number of participants with at least one post-baseline potentially clinically significant ECG finding is reported. bpm = beats per minute; QTcB = QT interval corrected using Bazett's formula; QTcF = QT interval corrected using Fridericia's formula.
Measured: Weeks 4, 12, 24, 36 and 52
Number of Participants With Adverse Events (AEs)
The intensity (severity) of each AE was defined as:
- Mild: caused minimal discomfort and did not interfere in a significant manner with normal activities.
- Moderate: sufficiently uncomfortable to produce some impairment of normal activities.
- Severe: incapacitating, preventing the patient from participating in normal activities.
The causal relationship between an AE and study drug was assessed by the investigator as Probable, Possible or Not Related; Related=AEs with causality of Possibly or Probably. A serious AE (SAE) was defined as any untoward medical occurrence that resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, led to a congenital anomaly/birth defect, or was an important medical event that either jeopardized the patient, required intervention to prevent any of the SAEs defined above, a suicide attempt or an abortion.
Measured: From the first dose of open-label study drug until 4 weeks after the last dose (up to 56 weeks)
Number of Participants With Potentially Clinically Significant Vital Sign Findings
Participants with at least one potentially clinically significant post-baseline vital sign finding. The definition of clinically significant is included in the table below for each parameter. SSBP = supine systolic blood pressure; SDBP = supine diastolic blood pressure.
Measured: Weeks 1, 2, 4, 8, 12, 16, 20, 24, 28, 36, 44 and 52
Secondary outcomes (7)
Change From Baseline in Hamilton Depression Scale-24 Item (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. Final Visit includes data from Week 52 or earlier for participants who didn't complete the 52 weeks.
Measured: Baseline and Weeks 1, 2, 4, 8, 12, 16, 20, 24, 28, 36, 44 and 52.
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 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. Final Visit includes data from Week 52 or earlier for participants who didn't complete the 52 weeks.
Measured: Baseline and Weeks 4, 24 and 52
Change From Baseline in the Hamilton Anxiety Scale (HAM-A) Total Score
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. Final Visit includes data from Week 52 or earlier for participants who didn't complete the 52 weeks.
Measured: Baseline and Weeks 4, 24 and 52
Change From Baseline in the Clinical Global Impression of Severity of Illness Scale
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. Final Visit includes data from Week 52 or earlier for participants who didn't complete the 52 weeks.
Measured: Baseline and Weeks 4, 24 and 52
Change From Baseline to the Final Visit in 36-item Short-form Health Survey (SF-36)
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).
Measured: Baseline and Week 52
Change From Baseline to the Final Visit in the Sheehan Disability Scale
The Sheehan Disability Scale (SDS) 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.
Measured: Baseline and Week 52
Health Care Resource Utilization Assessed by the Health Economic Assessment Questionnaire
Healthcare resource utilization was assessed by the Health Economic Assessment (HEA) questionnaire, which monitors 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.
Measured: Baseline and Week 52

The record lists 92 sites in United States, Germany, Russia, Poland, South Africa and 12 more countries. 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. 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 13 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?
Physical Examination Findings (time frame: Baseline and Week 52). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 13 Dec 2013.
