Trial Outcomes & Findings for Safety and Efficacy of Vilazodone in Major Depressive Disorder (NCT NCT01473381)

NCT ID: NCT01473381

Last Updated: 2014-08-08

Results Overview

The MADRS is a clinician-rated scale based on participant interviews. The scale assesses depressive symptomatology that occurred in participants during the week preceding each interview. Participants were rated on 10 items: Apparent sadness, reported sadness, inner tension, reduced sleep, reduced appetite, concentration difficulties, lassitude, inability to feel, pessimistic thoughts, and suicidal thoughts. Each item was scored on a 7-point scale from 0 (no symptoms) to 6 (symptoms of maximum severity). The total score was the sum of the scores of the 10 items and ranged from 0 to 60. A higher score indicates more depressive symptomatology. A negative change score indicates improvement.

PRIMARY outcome

Timeframe: Baseline to Week 10

Population: Intent-to-treat population: All randomized participants who received at least 1 dose of placebo, vilazodone, or citalopram and who had a baseline and at least 1 post-baseline assessment of the MADRS total score.

The MADRS is a clinician-rated scale based on participant interviews. The scale assesses depressive symptomatology that occurred in participants during the week preceding each interview. Participants were rated on 10 items: Apparent sadness, reported sadness, inner tension, reduced sleep, reduced appetite, concentration difficulties, lassitude, inability to feel, pessimistic thoughts, and suicidal thoughts. Each item was scored on a 7-point scale from 0 (no symptoms) to 6 (symptoms of maximum severity). The total score was the sum of the scores of the 10 items and ranged from 0 to 60. A higher score indicates more depressive symptomatology. A negative change score indicates improvement.

Population: Intent-to-treat population: All randomized participants who received at least 1 dose of placebo, vilazodone, or citalopram and who had a baseline and at least 1 post-baseline assessment of the MADRS total score.

The Clinical Global Impressions-Severity scale is a clinician-rated scale used to rate the severity of the participant's current state of mental illness compared with a patient population with major depressive disorder. In particular, the clinician is asked to respond to the following question: "Considering your total clinical experience with this population, how mentally ill is the patient at this time?" The patient is rated on the following 7-point scale: 1-normal, not at all ill, 2-borderline ill, 3-mildly ill, 4-moderately ill, 5-markedly ill, 6-severely ill, 7-among the most extremely ill patients. A higher score indicates more mental illness. A negative change score indicates improvement.

The MADRS is a clinician-rated scale based on participant interviews. The scale assesses depressive symptomatology that occurred in participants during the week preceding each interview. Participants were rated on 10 items: Apparent sadness, reported sadness, inner tension, reduced sleep, reduced appetite, concentration difficulties, lassitude, inability to feel, pessimistic thoughts, and suicidal thoughts. Each item was scored on a 7-point scale from 0 (no symptoms) to 6 (symptoms of maximum severity). The total score was the sum of the scores of the 10 items and ranged from 0 to 60. A higher score indicates more depressive symptomatology. A MADRS sustained response was defined as a MADRS total score ≤ 12 for at least the last 2 visits during the double-blind treatment period (Weeks 1-10). A total MADRS score ≤ 12 corresponds to an average score of 1 per item and is indicative of very low level of depressive symptoms.
