结局指标
主要结局
Change From Baseline to Week 6 in the Montgomery-Asberg Depression Rating Scale (MADRS) Total Score
时间窗: Baseline to Week 6
A 10-item scale for the evaluation of depressive symptoms. Each 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.
次要结局
- Change From Baseline to Week 12 in the Montgomery-Asberg Depression Rating Scale (MADRS) Total Score(Baseline to Week 12)
- Percentage of Patients Who Were Remitted (Defined as MADRS Total Score ≤10) at Week 6(Baseline to Week 6)
- Percentage of Patients Who Were Responders (Defined as a ≥50% Reduction From Baseline in MADRS Total Score) at Week 12(Baseline to Week 12)
- Percentage of Patients Who Were Remitted (Defined as MADRS Total Score ≤10) at Week 12(Baseline to Week 12)
- Percentage of Patients With Sustained Response From Week 6 to Week 12 (Defined as ≥50% Reduction From Baseline in the MADRS Total Score at Week 6 and Which is Maintained Through Week 12)(Week 6 to Week 12)
- Change From Baseline in Functional Impairment as Measured by the Change From Baseline in the Sheehan Disability Scale (SDS) Total Score(Baseline to Week 12)
- Change in Severity of Depressive Symptoms as Measured by the CGI-I Response (Defined as CGI-I Rating of "Very Much Improved" or "Much Improved") at Week 6(Baseline to Week 6)
- Change in Severity of Depressive Symptoms as Measured by the CGI-I Response (Defined as CGI-I Rating of "Very Much Improved" or "Much Improved") at Week 12(Baseline to Week 12)
- Percentage of Patients Who Were Responders (Defined as a ≥50% Reduction From Baseline in MADRS Total Score) at Week 6(Baseline to Week 6)
- Change in Severity of Depressive Symptoms as Measured by Change From Baseline in the Clinical Global Impression-Severity (CGI-S) Score(Baseline to Week 12)
- Change From Baseline in Self-rated Severity of Depressive Symptoms as Measured by Quick Inventory of Depressive Symptomatology Self-Rated 16-item Scale (QIDS-SR-16) Total Score(Baseline to Week 12)
