Proportion of patients experiencing relapse during the double-blind continuation phase.
Secondary efficacy variables will be measured from randomization to the end of the Double-Blind continuation Phase
Proportion of patients who achieve remission at the end of the double-blind continuation phase, where remission is defined by a total score of ≤7 on the HAM-D.
Secondary efficacy variables will be measured from randomization to the end of the Double-Blind continuation Phase
Change from randomization to the end of the double-blind continuation phase, on the Hospital Anxiety and Depression (HAD) total score and subscale scores.
