E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study was to assess the efficacy of duloxetine 60 mg once daily (QD) compared with placebo in the acute treatment of children (aged 7 through 11 years) and adolescents (aged 12 through 17 years) who met criteria for MDD without psychotic features, single or recurrent episode, as defined in the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision (DSM-IV-TR [APA 2000]). |
|
E.2.2 | Secondary objectives of the trial |
- To test assay sensitivity by comparing fluoxetine with placebo treatment in children (aged 7 through 11 years) and adolescents (aged 12 through 17 years) with MDD, during a 10-week, double-blind, acute treatment phase.
- To evaluate the efficacy of treatment with duloxetine 30 and 60 mg QD compared with placebo in the treatment of children (aged 7 through 11 years) and adolescents (aged 12 through 17 years) with MDD, during a 10-week, double-blind, acute treatment phase, with a variety of measures.
- To evaluate the safety and tolerability of treatment with duloxetine 30 and 60 mg QD compared with placebo in the treatment of children (aged 7 through 11 years) and adolescents (aged 12 through 17 years) with MDD, during a 10-week, double-blind, acute treatment phase.
- To characterize the pharmacokinetics (PK) of duloxetine at steady-state in the treatment of children (aged 7 through 11 years) and adolescents (aged 12 through 17 years) with MDD. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |

E.5 End points |
E.5.1 | Primary end point(s) |
Change From Baseline in Children's Depression Rating Scale-Revised (CDRS-R) Total Score at Week 10 Endpoint [ Time Frame: Baseline, Week 10 ]
CDRS-R Total score measure the presence and severity of depression in children. The scale consists of 17 items scored on a 1-to-5- or 1-to-7-point scale. A rating of 1 indicates normal functioning. Total scores range from 17 to 113. In general, scores below 20 indicate an absence of depression, scores of 20 to 30 indicate borderline depression, and scores of 40 to 60 indicate moderate depression. Least Square (LS) means are adjusted for baseline, pooled investigator, age category, visit, treatment, treatment*visit, age category*visit and baseline*visit. |
