Safety and Tolerability of Vortioxetine (Lu AA21004) in Adults With Major Depressive Disorder

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.

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.
