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.

Condition or Disease Intervention/Treatment Phase
Phase 3

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

    1. 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

    1. 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.

    Description 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.
