Arms and Interventions

Participant Group / Arm	Intervention / Treatment
EXPERIMENTAL: Levomilnacipran ER 40-80 mg/day; Levomilnacipran extended release (ER) capsules, orally, 10 milligram per day (mg/day) on Days 1 to 3, 20 mg/day on Days 4 to 7, and 40 mg/day from Week 2 through Week 8 of the Double-blind Treatment Period followed by levomilnacipran ER 40 mg/day on Days 1 and 2, and then 20 mg/day from Day 3 through Day 7 in the Down-taper Period.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change From Baseline in Children's Depression Rating Scale- Revised (CDRS-R)	The CDRS-R is a semi-structured, clinician-rated instrument designed for use with children and adolescents between the ages of 6-17 years. It contains 17 ordinally-scaled items that evaluate the presence and severity of symptoms commonly associated with childhood depression and is scored on a 1-to-5- or 1-to-7-point scale. Rating of 1 indicates normal function. The CDRS-R total score ranges from 17 to 113; higher score indicates more severe depression. A negative change from Baseline indicates improvement. Mixed Model for Repeated Measures (MMRM) was used for analysis.	Baseline (Week 0) to Week 8

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change From Baseline in Clinical Global Impression-Severity (CGI-S) Scale	The CGI-S is a clinician-rated scale used to rate the severity of the participant's current state of mental illness compared with MDD population. The participant was rated on a scale from 1 to 7, where 1=normal, not at all ill and 7=among the most extremely ill participants. Higher score indicates worsening of mental illness. A negative change from Baseline indicates improvement. MMRM was used for analysis.	Baseline (Week 0) to Week 8
