A comparison of real-world effectiveness of vortioxetine along the treatment algorithm for major depressive disorder

OBJECTIVE: To evaluate the effectiveness of vortioxetine in major depressive disorder (MDD) when used as a first-line versus second-line treatment or later.

METHODS: This was a post-hoc analysis of three 3-month non-interventional, prospective studies of vortioxetine in MDD - REVIDA (Malaysia, Philippines, Singapore, Thailand), PREVIDA (Pakistan) and TREVIDA (Taiwan). Improvements in depressive symptoms (PHQ-9, CGI-S), cognitive function (PDQ-D) and work productivity (WPAI) were compared between studies, and in a pooled analysis of patients using vortioxetine as first line versus second-line treatment or later. Safety was compared between studies.

RESULTS: Overall, 798 patients were analyzed (PREVIDA =425, REVIDA =130, TREVIDA =243). Most patients in PREVIDA (60.5%)/REVIDA (57.4%) used vortioxetine as first-line treatment versus TREVIDA (21.8%). Generally, greater improvements from baseline were observed across outcome measures in PREVIDA/REVIDA versus TREVIDA (Month 3, p
