Trial Outcomes & Findings for Safety and Efficacy of Vilazodone in Adolescent Patients With Major Depressive Disorder (NCT NCT01878292)

NCT ID: NCT01878292

Last Updated: 2019-12-24

Results Overview

The Children's Depression Rating Scale-Revised (CDRS-R) total score ranges from 17 (minimal or no symptoms of depression) to 133 (indicative of depression) is a semi-structured, clinician-rated instrument designed for use with children and adolescents between the ages of 6 to 17 years of age and their caregivers. The CDRS-R evaluates the presence and severity of symptoms commonly associated with depression in childhood.

PRIMARY outcome

Timeframe: From Baseline to week 8

Population: The Intent-to-Treat (ITT) Population will consist of all patients in the Safety Population who had baseline and at least 1 postbaseline assessment of the Children's Depression Rating Scale-Revised (CDRS-R) total score.

The Children's Depression Rating Scale-Revised (CDRS-R) total score ranges from 17 (minimal or no symptoms of depression) to 133 (indicative of depression) is a semi-structured, clinician-rated instrument designed for use with children and adolescents between the ages of 6 to 17 years of age and their caregivers.

SECONDARY outcome

Timeframe: From Baseline to Week 8

Population: The Intent-to-Treat (ITT) Population will consist of all patients in the Safety Population who had baseline and at least 1 postbaseline assessment of the Children's Depression Rating Scale-Revised (CDRS-R) total score.

The Clinical Global Impressions-Severity (CGI-S) is a clinician-rated instrument used to rate the severity of the patient's current state of mental illness compared with the clinician's total experience with patients with major depressive disorder (MDD). The severity of the patient's MDD was rated on a scale from 1 to 7, with 1 indicating a normal state and 7 indicating a patient who is among the most extremely ill patients.
