Depression affects approximately 2.5% of children and 8% of adolescents. Escitalopram is the S-enantiomer of citalopram. Both escitalopram and citalopram are selective serotonin reuptake inhibitors (SSRIs) and are used to treat depression in adults. This study is designed to provide a systematic evaluation of the safety and efficacy of escitalopram in the treatment of depressed pediatric patients, 12 to 17 years of age. Patients completing the study will be eligible to enter an open-label extension study.

Primary Outcome Measures:
  • Change in Children's Depression Rating Scale - Revised (CDRS-R) Total Score [ Time Frame: Baseline to end of week 8 ] [ Designated as safety issue: No ]
    Change from baseline to week 8 in Children's Depression Rating Scale total score. The scale measures 17 depressive symptoms, of which 3 are rated 1-5 and 14 are rated 1-7 (1 = no symptom difficulties; 5 or 7 = severe clinically significant difficulties) for a total score range of 17-113.

Secondary Outcome Measures:
  • Clinical Global Impressions - Improvement [ Time Frame: CGI-I score at the end of Week 8 ] [ Designated as safety issue: No ]
    Clinical Global Impressions - Improvement score at the end of week 8. The scale rates improvement or worsening of patient mental health relative to baseline on a scale from 1 (very much improved) to 7 (very much worse).
