Outcomes

Primary Outcomes

Change From Baseline in the 17-item Hamilton Rating Scale for Depression (HAM-D17) Total Score at Day 15

The HAM-D total score comprised a sum of 17 individual item scores.The total score could range from 0 to 52. Higher scores indicated a greater degree of depression.

Time frame: Baseline, Day15

Secondary Outcomes

Change From Baseline in the 17-item Hamilton Rating Scale for Depression (HAM-D17) Total Score at all other time points

Time frame: Day3,8,21 and 28

Change From Baseline in the Montgomery and Åsberg Depression Rating Scale (MADRS) Total Score at Day 15 and All Other Time Points

The MADRS was a ten-item diagnostic questionnaire which psychiatrists used to measure the severity of depressive episodes in participants with mood disorders. It was designed as an adjunct to the HAM-D, to be more sensitive than the Hamilton Scale to the changes brought on by antidepressants and other forms of treatment. Each item yielded a score of 0 to 6. The MADRS total score was calculated as the sum of the 10 individual item scores, which ranged from 0 to 60. Higher MADRS scores indicated more severe depression. A negative change from baseline indicated less severe depression. A positive change from baseline indicated more severe depression. The analysis was performed in participants included in Part A of the study.

Time frame: Day 3,8,15,21 and 28

Change From Baseline in Hamilton Anxiety Rating Scale (HAM-A) Total Score at All Time Points

The 14-item HAM-A was used to rate the severity of symptoms of anxiety. Each of the 14 items was defined by a series of symptoms, and measured both psychic anxiety (mental agitation and psychological distress) and somatic anxiety (physical complaints related to anxiety). Scoring for HAM-A was calculated by assigning scores of 0 (not present) to 4 (very severe), with a total score range of 0 to 56. The HAM-A total score was calculated as the sum of the 14 individual item scores. A negative change from baseline indicated less anxiety. A positive change from baseline indicated more anxiety. The analysis was performed in participants included in Part A of the study.
