Primary Outcome Measures :

1. Change From Baseline in Total Montgomery Asberg Depression Rating Scale (MADRS) at 8 Weeks. [ Time Frame: Change from baseline in MADRS total score at week 8 ]
   The MADRS is a 10-item clinician-rated scale that was used to assess depressive symptomatology over the patient's prior week. Patients were rated on 10 items designed to assess feelings of sadness, lassitude, pessimism, inner tension, suicidality, reduced sleep or appetite, difficulty concentrating, and lack of interest. Each item was scored on a 7-point Likert scale; a score of 0 indicated the absence of symptoms, and a score of 6 indicated symptoms of maximum severity. The total score range is 0 to 60 (higher score indicates a greater severity of symptoms).

Secondary Outcome Measures :

1. Change From Baseline in Hamiltion Rating Scale for Depression (HAM-D) at Week 8 [ Time Frame: Change from baseline in HAM-D at week 8 ]
   The HAMD is a clinician-rated 24-item scale was used to rate the patient's depressive state. It was also used to identify obsessive-compulsive, genital, and somatic symptoms, as well as diurnal variation in the presence of symptoms. Each item was scored on a 3, 4 or 5-point Likert scale. A score of 0 indicated the absence of symptoms, and a score of 2, 3 or 4 indicated symptoms of maximum severity. The total score range is 0 to 74 (higher score indicates a greater depressive state).
