Safety and Efficacy of Levomilnacipran ER in Adolescent Participants With Major Depressive Disorder
Study Details
Study Description
Brief Summary
The purpose of this study is to evaluate the efficacy, safety, and tolerability of levomilnacipran ER relative to placebo in adolescent outpatients (12-17 years) with Major Depressive Disorder (MDD). In addition, the study is designed to obtain pharmacokinetics (PK) data to guide dose selection for future pediatric studies of levomilnacipran.

Detailed Description
Study LVM-MD-11 is a randomized, double-blind, placebo- and active-controlled, parallel group, fixed-dose study in adolescent patients, ages 12-17 years. The study will be approximately 10 weeks in duration:
-
1-week screening/washout period
-
8-week double-blind treatment period
-
1-week double-blind down-taper period
Participants who meet the eligibility criteria at Visit 2 (Baseline) will be randomized to 1 of 4 treatment groups: placebo, levomilnacipran 40 mg/day, levomilnacipran 80 mg/day, or fluoxetine 20 mg/day.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Placebo Comparator: Placebo Participants received 2 dose matched over-encapsulated placebo capsules, once daily, orally during the Double-blind Treatment Period up to 8 weeks followed by a 1 week Taper-down Period if applicable as determined by the investigator. |
Drug: Placebo
Matched over-encapsulated placebo capsules administered orally on Day 1 to Week 8.
|
Experimental: Levomilnacipran 40 mg Participants received over-encapsulated levomilnacipran extended release (ER) 40 mg/day capsules orally starting at a dose of 10 mg/day on Day 1-2, 20 mg/day on Days 3-7 and 40 mg/day on Week 2 through Week 8 during the Double-Blind Treatment Period, followed by a 1-week Double-Blind Taper-down Period if applicable as determined by the investigator. Participants received 1 dose matched placebo capsule each day to maintain the blind. |

Outcome Measures
Primary Outcome Measures
- Change From Baseline in Children's Depression Rating Scale-Revised (CDRS-R) Total Score [Baseline (Week 0) to Week 8]
CDRS-R is a 17-item scale measuring 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.
Secondary Outcome Measures
- Change From Baseline in Clinical Global Impression-Severity (CGI-S) Scale [Baseline (Week 0) to Week 8]
The CGI-S is a clinician-rated scale used to rate the severity of the participants current state of mental illness compared with MDD population. The participant was rated on a scale from 1 to 7, where 1= Very much improved; 2= Much improved; 3= Minimally improved; 4= No change; 5= Minimally worse; 6= Much worse; 7= Very much worse. Higher score indicates worsening of mental illness. A negative change from Baseline indicates improvement. MMRM was used for analysis.
