Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • The patient has MDD, diagnosed according to Diagnostic and Statistical Manual of Mental Disorders, 4th edition, Text Revision (DSM-IV-TR™) recurrent major depressive disorder (MDD) (classification 296.3x).
  • The patient has a MADRS total score ≥26.
  • The patient has had the current major depressive episode (MDE) for ≥3 months.
  • The patient is aged ≥18 and ≤65 years.
  • The patient is employed full or part-time (defined as minimum 50% full time working hours per week). Part time work should not be due to a medical or mental illness other than MDD.
  • The patient has been in the current job/position for at least 3 months.
  • The patient has no plans to change jobs or retire within treatment period.
  • The patient is not on a sick leave, and at the Screening and Randomisation Visits, there are no plans to send the patient on a sick leave.
  • The patient is not receiving disability benefits.

Exclusion criteria:

  • The patient has a score ≥70 on the DSST (number of correct symbols) at the Baseline Visit.
  • The patient is, in the opinion of the investigator, not able to complete the neuropsychological tests validly at the Baseline Visit.
  • The patient has physical, cognitive, or language impairment of such severity as to adversely affect the validity of the data derived from the neuropsychological tests.
  • The patient is diagnosed with reading disability (dyslexia).
  • The patient has a history of lack of response to previous adequate treatment with vortioxetine or paroxetine.
  • The patient has any current psychiatric disorder or Axis I disorder (according to DSM-IV-TR™ criteria) other than MDD, as assessed using MINI.
  • The patient has a current or has had a diagnosis of dysthymic disorder within 3 months preceding the onset of current episode (DSM-IV-TR™ criteria).
  • The patient has borderline, schizotypal, schizoid, paranoid, or histrionic, antisocial personality disorders (axis II) as comorbid or primary diagnosis (DSM-IV-TR™ criteria).
  • The patient suffers from personality disorders, mental retardation, pervasive development disorder, attention-deficit/hyperactivity disorder, organic mental disorders, or mental disorders due to a general medical condition (DSM-IV-TR™ criteria).
  • The patient has a current diagnosis or history of manic or hypomanic episode, schizophrenia or any other psychotic disorder, including major depression with psychotic features (DSM-IV-TR™ criteria).

Other protocol-defined inclusion and exclusion criteria may apply.
