Primary Outcome Measures:
  • Change in the Montgomery Asberg Depression Rating Scale (MADRS) Total Score From Randomization to End of Treatment [ Time Frame: Randomization (Week 8) to end of treatment (Week 16) ] [ Designated as safety issue: No ]
    A 10-item scale for the evaluation of depressive symptoms. Each Montgomery Asberg Depression Rating Scale (MADRS) item is rated on a 0 to 6 scale. The MADRS total score is calculated as the sum of the 10 individual item scores; the total score can range from 0 to 60. Higher MADRS scores indicate higher levels of depressive symptoms.
