简要总结
The purpose of this study is to evaluate the efficacy of vortioxetine, once daily (QD), compared with placebo in adults with major depressive disorder.
详细描述
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 462 patients. Participants were randomly assigned (by chance, like flipping a coin) to one of the three treatment groups-which remained undisclosed to the patient and study doctor during the study (unless there was an urgent medical need):
- Vortioxetine 10 mg
- Vortioxetine 20 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.

- •Presence or history of a clinically significant neurological disorder (including epilepsy)
- •Neurodegenerative disorder.
- •Any Axis II disorder that might compromise the study.
- •Has a thyroid stimulating hormone value outside the normal range at the Screening Visit that is deemed clinically significant by the investigator.
- •Has clinically significant abnormal vital signs as determined by the investigator.
- •Has an abnormal Electrocardiogram.
- •Has an alanine aminotransferase, aspartate aminotransferase or total bilirubin level greater than 1.5 times the upper limits of normal.
- •Has a previous history of cancer that had been in remission for less than 5 years prior to the first dose of study medication.

结局指标
主要结局
Change From Baseline in Montgomery-Åsberg Depression Rating Scale (MADRS) Total Score
时间窗: Baseline and Week 8
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.
