Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline in the Children's Depression Rating Scale -Revised (CDRS-R) Total Score at Week 8
Time Frame: Baseline and Week 8
|
The CDRS-R has been widely used for the evaluation of children and adolescents with major depressive disorder (MDD).
The CDRS-R total score is the sum of the responses to 17 questions.
Each question is graded on a 5- or 7-point scale.
The highest possible score is 113 (the most severe measure of depression), and the lowest is 17 (not suffering from depression).
CDRS-R scores were assessed by the investigator.
The change from Baseline in the CDRS-R total score was calculated as the total score at Week 8 minus the total score at Baseline.
The data were adjusted with the total score at Baseline.

Number of Clinical Global Impression - Global Improvement (CGI-GI) Responders at Weeks 1, 2, 3, 4, 6, and 8
Time Frame: Weeks 1, 2, 3, 4, 6, and 8
|
CGI-GI is assessed on an 8-grade scale: 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.
CGI-GI was assessed by the investigator.
Participants who were rated as 1 (very much improved) or 2 (much improved) were categorized as CGI-GI responders.
|
Weeks 1, 2, 3, 4, 6, and 8
|
Change From Baseline in the Clinical Global Impression - Severity of Illness (CGI-SI) Score at Weeks 1, 2, 3, 4, 6, and 8
Time Frame: Baseline and Weeks 1, 2, 3, 4, 6, and 8
|
CGI-SI is assessed on an 8-grade scale: 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.
CGI-SI was assessed by the investigator.
The change from Baseline in CGI-SI score was calculated as the score at Weeks 1, 2, 3, 4, 6, and 8 minus the score at Baseline.

Baseline and Weeks 1, 2, 3, 4, 6, and 8
|
Plasma Paroxetine Concentrations at 12 Hours and 24 Hours After Administration of Study Drug at Week 8 or Withdrawal
Time Frame: Week 8 or Withdrawal (up to Week 8)
|
Summary statistics for the plasma paroxetine concentrations at each time point were calculated by the dosage just before blood sampling using data from participants in whom plasma samples were collected at either 12 hours (plus or minus 2 hours) or 24 hours (plus or minus 2 hours) after the last administration of the study drug at Week 8 or Withdrawal (up to Week 8).
