Primary Outcome Measures:
  • Change from Baseline to Week 8 on the total score Hamilton Depression Rating Scale [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • To demonstrate less sexual dysfunction in patients with MDD receiving agomelatine compared to paroxetine, as measured by the change from baseline to Week 8 on the total score of the Arizona Sexual Experience Scale (ASEX). [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
  • Proportion of patients who demonstrate clinical improvement where improvement is defined by a score of 1 or 2 on the Clinical Global Impression Improvement (CGI-I) scale at Week 8. [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
  • Proportion of patients with MDD who achieve remission, [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
  • Change from baseline to Week 8 on the total score and Anxiety subscale of the Hospital Anxiety and Depression Scale (HAD). [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
