- Primary Outcome Measures
Name Time Method Change From the End of Phase A (Week 8 Visit) to the End of Phase B (Week 14 Visit) in the Montgomery Asberg Depression Rating Scale (MADRS) Total Score. Baseline (end of week 8) to Week 14 The MADRS was utilized as the primary efficacy assessment of a participants level of depression. The MADRS consisted of 10 items, all rated on a 0 to 6 scale with 0 being the "best" rating and 6 being the "worst" rating. The MADRS Total Score is the sum of ratings for all 10 items; therefore, possible total scores range from 0 to 60. The MADRS total score were to be unevaluable if less than 8 of the 10 items were recorded. If 8 or 9 of the 10 items were recorded, the MADRS total score was the mean of the recorded items multiplied by 10 and then rounded of to the first decimal place.
- Secondary Outcome Measures
Name Time Method Change From End of Phase A (Week 8 Visit) in MADRS Total Score for Every Trial Week Visit in Phase B. Baseline (end of week 8) to Week 14 The MADRS was utilized as the primary efficacy assessment of a participants level of depression. The MADRS consisted of 10 items, all rated on a 0 to 6 scale with 0 being the "best" rating and 6 being the "worst" rating. The MADRS Total Score is the sum of ratings for all 10 items; therefore, possible total scores range from 0 to 60. The MADRS total score were to be unevaluable if less than 8 of the 10 items were recorded. If 8 or 9 of the 10 items were recorded, the MADRS total score was the mean of the recorded items multiplied by 10 and then rounded of to the first decimal place.
Change From End of Phase A (Week 8) to Phase B in Sheehan Disability Scale (SDS) Score. Baseline (end of week 8) to Week 14 The SDS was a self-rated instrument used to measure the effect of the participants symptoms on work/school, social life, and family/home responsibilities. For each of the three items, scores ranged from 0 through 10. The number most representative of how much each area was disrupted by symptoms was marked along the line from 0= not at all, to 10= extremely. Scores of 5 and above are associated with significant functional impairment. The SDS total score ranges from 0 to 30, with higher values indicating greater disruption in the participant's work/social/family life. For the work/school item, no response was to be entered if the participant did not work or go to school for reasons unrelated to the disorder and a response therefore not being applicable. The Mean SDS score were calculated over the three item scores. All three item scores were needed to be available with the exception of the work/school item score when this item was not applicable.
Change From End of Phase A (Week 8) to End of Phase B (Week 14) in the Hamilton Depression Rating Scale 17-item Version (HAM-D17) Total Score. Baseline (end of week 8) to Week 14 The HAM-D17 was utilized as a secondary assessment of a participants level of depression. The HAM-D (17-Item) consisted of 17 items. Eight items were rated on a 0 to 2 scale (items 4, 5, 6, 12, 13, 14, 16 and 17), while nine items (items 1, 2, 3, 7, 8, 9, 10, 11, and 15) were rated on a 0 to 4 scale (twice the weight of the other items). For all of these items, 0 was the "best" rating and the highest score (2 or 4) was the "worst" rating. The possible total scores were from 0 to 52.
Number of Participants With MADRS Response During Phase B Relative to the End of Phase A (Week 8) Visit. Baseline (end of week 8) to Week 14 A MADRS response was defined as \>=50 percent reduction in MADRS Total Score from end of Phase A (Week 8 visit). The MADRS consisted of 10 items, all rated on a 0 to 6 scale with 0 being the "best" rating and 6 being the "worst" rating. The MADRS Total Score is the sum of ratings for all 10 items; therefore, possible total scores range from 0 to 60. The MADRS total score were to be unevaluable if less than 8 of the 10 items were recorded. If 8 or 9 of the 10 items were recorded, the MADRS total score was the mean of the recorded items multiplied by 10 and then rounded of to the first decimal place.
Change From End of Phase A (Week 8 Visit) to Phase B by Study Week in Inventory of Depressive Symptomatology (Self-Report) (IDS-SR) Total Score. Baseline (end of week 8) to Week 14 The IDS-SR was a 30-item self-report measure, that was used to assess core diagnostic depressive symptoms as well as atypical and melancholic symptom features of major depressive disorder (MDD). For individual items, the scores range from 0 to 3. The IDS-SR are scored by summing responses to 28 of the 30 items to obtain a total score ranging from 0 to 84, higher values indicate greater disruption in the depressive symptoms.
Number of Participants With MADRS Remission During Phase B Relative to the End of Phase A (Week 8) Visit. Baseline (end of week 8) to Week 14 A MADRS remission was defined as MADRS Total Score =\< 10 and \>= 50 percent reduction in MADRS Total Score from end of Phase A (Week 8 visit). The MADRS consisted of 10 items, all rated on a 0 to 6 scale with 0 being the "best" rating and 6 being the "worst" rating. The MADRS Total Score is the sum of ratings for all 10 items; therefore, possible total scores range from 0 to 60. The MADRS total score were to be unevaluable if less than 8 of the 10 items were recorded. If 8 or 9 of the 10 items were recorded, the MADRS total score was the mean of the recorded items multiplied by 10 and then rounded of to the first decimal place.
Number of Participants With CGI-Improvement Response During Phase B Relative to the End of Phase A (Week 8). Baseline (end of week 8) to Week 14 CGI-I Response was defined as a CGI-I score of 1 (very much improved) or 2 (much improved).
Change From End of Phase A (Week 8 Visit) to Phase B by Study Week in Clinical Global Impression- Severity Illness Scale (CGI-S) Score. Baseline (end of week 8) to Week 14 The severity of illness for each participant was rated using the CGI-S. To perform this assessment, the investigator had to answer the following question: "Considering your total clinical experience with this particular population, how mentally ill is the participant at this time?" Response choices included: 0 = not assessed; 1 = normal, not at all ill; 2 = borderline mentally ill; 3 = mildly ill; 4 = moderately ill; 5 = markedly ill; 6 = severely ill; and 7 = among the most extremely ill participants.
Clinical Global Impression- Improvement Scale (CGI-I) Score by Study Week in Phase B Relative to End of Phase A. Baseline (end of week 8) to Week 14 The efficacy of study medication was rated for each participant using the CGI-I. The study physician would rate the participants total improvement whether or not it is due entirely to drug treatment. Response choices included: 0 = not assessed, 1 = very much improved, 2 = much improved, 3 = minimally improved, 4 = no change, 5 = minimally worse, 6 = much worse, and 7 = very much worse.
