Overview
Brief Summary
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.
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.
Investigators
Eligibility Criteria
Inclusion Criteria
- •Has completed the double blind treatment period of either study Lu AA21004_304 (NCT00672620) or LuAA21004_305 (NCT00735709) immediately prior to enrollment in the extension study (ie, the baseline visit is the same visit as the completion visit of the double blind treatment of the preceding protocol).
- •Suffers from a major depressive episode as the primary diagnosis according to Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision (DSM-IV-TR) criteria (classification code 296.xx) at entry into the prior Lu AA21004_304 or Lu AA21004_305 study.
Exclusion Criteria
- •In addition to meeting the exclusion criteria for studies Lu AA21004_304 or Lu AA21004_305 at the time of enrollment into those studies respectively, with the exception of the criteria prohibiting previous exposure to Lu AA21004 and investigational drugs, and the criteria prohibiting patients with increased intraocular pressure, or risk of acute narrow-angle glaucoma, the following exclusion criteria apply:
- •Has Major Depressive Disorder for whom other psychiatric disorders (mania, bipolar disorder, schizophrenia, or any psychotic disorder) have been diagnosed during the prior study.
- •The participant, in the investigator's opinion, has a significant risk of suicide and/or a score of ≥5 points on item 10 (suicidal thoughts) of the Montgomery Åsberg Depression Rating Scale.
- •The participant, in the opinion of the investigator, is unlikely to comply with the clinical study protocol or is unsuitable for any reason.
- •Has a clinically significant moderate or severe ongoing adverse event related to study medication from the prior study.
- •Has used/uses disallowed concomitant medication.
Arms & Interventions
Vortioxetine
Vortioxetine 2.5 mg, 5 mg or 10 mg, encapsulated tablets, orally, once daily for up to 52 weeks. For the first week of treatment all participants received 5 mg/day vortioxetine, thereafter, the dose could be increased to 10 mg/day or decreased to 2.5 mg/day, based on participant's response and tolerability as judged by the investigator.
Intervention: Vortioxetine
Outcomes
Primary Outcomes
Physical Examination Findings
Time Frame: Baseline and Week 52
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.
Number of Participants With Potentially Clinically Significant Laboratory Evaluation Findings
Time Frame: Weeks 4, 8, 12, 20, 28, 36, 44 and 52
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.
Number of Participants With Adverse Events (AEs)
Time Frame: From the first dose of open-label study drug until 4 weeks after the last dose (up to 56 weeks)
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.
Number of Participants With Potentially Clinically Significant Vital Sign Findings
Time Frame: Weeks 1, 2, 4, 8, 12, 16, 20, 24, 28, 36, 44 and 52
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.
Number of Participants With Potentially Clinically Significant Electrocardiogram (ECG) Findings
Time Frame: Weeks 4, 12, 24, 36 and 52
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.
