Study Endpoints
Primary Endpoints
Parts A and B: Change From Baseline in the 17-Item Hamilton Rating Scale for Depression (HAM-D) Total Score at Day 15
Parts A and B: Baseline, Day 15

The 17-item HAM-D is used to rate the severity of depression in participants who are already diagnosed as depressed. Items scored in a range of 0 to 2 include: insomnia (early, middle, late), somatic symptoms (gastrointestinal and general), genital symptoms, loss of weight, and insight. The following items are scored in a range of 0 to 4: agitation, depressed mood, feelings of guilt, suicide, work and activities, retardation, anxiety (psychic and somatic), and hypochondriasis. The HAM-D total score was calculated as the sum of the 17 individual item scores and could range from 0 to 52. Higher scores indicated more severe depression. A negative change from Baseline indicates less depression.

Secondary Endpoints
Parts A and B: Change From Baseline in the HAM-D Total Score at Days 3, 8, 21 and 45
Part B: Baseline, Days 3, 8, 21 and 45
Parts A and B: Percentage of Participants With HAM-D Response
Part B: Days 3, 8, 15, 21 and 45
Parts A and B: Percentage of Participants With HAM-D Remission
Part B: Days 3, 8, 15, 21 and 45
