Design outcomes

Primary

MeasureTime frameDescription
Change From Baseline in MADRS Total Score After 6 Weeks of TreatmentBaseline and Week 6The Montgomery Åsberg Depression Rating Scale (MADRS) is a depression rating scale consisting of 10 items, each rated 0 (no symptom) to 6 (severe symptom). The 10 items represent the core symptoms of depressive illness. The rating should be based on a clinical interview with the patient, moving from broadly phrased questions about symptoms to more detailed ones, which allow a precise rating of severity, covering the last 7 days. Total score from 0 to 60. The higher the score, the more severe.

Secondary

MeasureTime frameDescription
Change From Baseline in HAM-D 24 Total Score After 6 Weeks of TreatmentBaseline and Week 6The 24-item Hamilton Depression Rating Scale (HAM-D) is based on the 21-item HAM-D plus an additional 3 items (helplessness, hopelessness, and worthlessness). The observer makes his/her assessment on the basis of a specific statement, content, tone, facial expression, and gestures of the patient during the interview, and scores each item from 0 to 2 or 0 to 4. Total score from 0 to 76. The higher the score, the more severe.
Change From Baseline in HAM-A Total Score After 6 Weeks of TreatmentBaseline and Week 6The Hamilton Anxiety Rating Scale (HAM-A) consists of 14 items that assess anxious mood, tension, fear, insomnia, intellectual (cognitive) symptoms, depressed mood, behaviour 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 score from 0 to 56. The higher the score, the more severe.
Change From Baseline in CGI-S Score After 6 Weeks of TreatmentBaseline and Week 6The Clinical Global Impression - Severity of Illness (CGI-S) is a 7-point scale rated from 1 (normal, not at all ill) to 7 (among the most extremely ill patients). The investigator should use his/her total clinical experience with this patient population to judge how mentally ill the patient is at the time of rating.

Participant flow

Recruitment details

Outpatients with Major Depressive Episode (MDE) were recruited from psychiatric settings.

Pre-assignment details

Eligible patients were randomised equally (1:1:1:1) to one of the 4 treatment arms for a 6-week double-blind treatment period. The doses of Vortioxetine were 5 mg/day or 10 mg/day for 6 weeks. The dose of venlafaxine was 75 mg/day for 4 days, 150 mg/day for the following 3 days, and 225 mg/day for the remainder of the treatment period.
