About

The purpose of this study is to determine the efficacy and safety of once daily vortioxetine (Lu AA21004) in adults with major depressive disorder.

Full 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 vortioxetine.

The study enrolled 600 patients. Participants were randomly assigned (by chance, like flipping a coin) to one of the two treatment groups-which remained undisclosed to the patient and study doctor during the study (unless there was an urgent medical need):

Vortioxetine 5 mg
Placebo (dummy inactive pill) - 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 approximately 94 days. Participants made 8 visits to the clinic, and were contacted by telephone 1 week, 2 weeks, and 4 weeks after the last dose of study drug for a follow-up assessment.
