- Change in Montgomery Asberg Depression Rating Scale (MADRS) [ Time Frame: From baseline to Week 6 ]
- Change in Clinical Global Impression Score - Severity (CGI-S) [ Time Frame: From baseline to Week 6 ]

- Safety: Incidence of adverse events [ Time Frame: approximately 2 years ]
- Proportion of patients exhibiting remission (MADRS </= 10) after 6 weeks of treatment [ Time Frame: approximately 2 years ]
- Proportion of patients exhibiting response (reduction in MADRS >/= 50% of baseline score) after 6 weeks of treatment [ Time Frame: approximately 2 years ]
