Primary Outcome Measures:
  • The mean change in the Clinical Global Impressions Scale for Bipolar Disorder (CGI-BP)Severity score as well as the change in CGI-BP. [ Time Frame: D0, D21 and D-end ]

Secondary Outcome Measures:
  • Percentage of responders defined by a decrease of at least 50% of the CGI-BP. [ Time Frame: D0 and D-end ]
  • Percentage of responders defined by a decrease of at least 50% of the CGI-BP. [ Time Frame: D0 and D21 ]
  • Time to achieve 50% and 30% improvement in the CGI-BP score. [ Time Frame: From randomization to the end of the study ]
  • Time to a sustained improvement in the CGI-BP. [ Time Frame: From randomization to the end of the study ]
  • Time to antidepressants use. [ Time Frame: From randomization to the end of the study ]
  • Time to drop-out for any reason. [ Time Frame: From randomization to the end of the study ]
  • Safety :Occurrence of any side effect leading to treatment discontinuation. [ Time Frame: From inform consent signed until patient's recovery or stabilization ]
