Further study details as provided by Novartis:

Primary Outcome Measures:
  • To evaluate the change from Baseline to Week 8 on the total score of the clinician rated 17-Item Hamilton Depression Rating Scale (HAM-D17) [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • To evaluate the proportion of patients who demonstrate clinical improvement at Week 8, where improvement is defined by a score of 1 or 2 on the CGI-I scale [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
  • To evaluate the proportion of patients who achieve remission at Week 8, where remission is defined by a total score of < or =7 on the HAM-D17 [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
  • To evaluate efficacy with respect to the proportion of patients who demonstrate clinical response, where response is defined by a reduction of at least 50% in the baseline HAM-D17 at week 8 [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
  • To evaluate the change from baseline to week 8 on the subscale scores (Maier, anxiety, retardation and sleep) of the clinician-rated HAM-D17 [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
  • To evaluate subjective sleep (onset and quality), as measured by the scores on the Leeds Sleep Evaluation Questionnaire (LSEQ) at week 8 [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
