Escitalopram in Patients With Generalized Anxiety Disorder

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate the effect of escitalopram after 8 weeks of treatment in patients with Generalized Anxiety Disorder (GAD), to evaluate proportion of patients who respond to escitalopram during the treatment period, and to evaluate safety of escitalopram.

Detailed Description
-----------------
The study will be performed in Russia, as an open-label, uncontrolled, one arm trial. The patients will receive escitalopram for 8 weeks. Start and maintenance dosages as well as dose titration will be left to the investigators' decision (5 to 20 mg/day), in accordance with the national Summary of Products Characteristics (SPC).

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Effect of Escitalopram After 8 Weeks of Treatment in Patients With GAD Using the Hamilton Anxiety Scale (HAMA) | The HAMA is a 14-item rating scale designed to assess global anxiety symptoms. Each symptom is rated from 0 (absent) to 4 (severe). The total score of the 14 items ranges from 0 to 56. | baseline and 8 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Effect of Escitalopram After 8 Weeks Using the Clinical Global Impression (CGI-I) | The CGI-I provides the clinician's impression of the patient's improvement (or worsening). The clinician assesses the patient's condition relative to a baseline on a 7-point scale ranging from 1 (very much improved) to 7 (very much worse). | baseline and 8 weeks | 
| Effect of Escitalopram After 8 Weeks Using the Clinical Global Impression (CGI-S) | The CGI-S provides the clinician's impression of the patient's current state of mental illness. The clinician uses his or her clinical experience of this patient population to rate the severity of the patient's current mental illness on a 7-point scale ranging from 1 (Normal - not at all ill) to 7 (among the most extremely ill patients). | baseline and 8 weeks | 
| Percentage of Patients Who Responded to Escitalopram After 8 Weeks of Treatment Using CGI-I <= 2 | The CGI-I provides the clinician's impression of the patient's improvement (or worsening). The clinician assesses the patient's condition relative to a baseline on a 7-point scale ranging from 1 (very much improved) to 7 (very much worse). | baseline and 8 weeks | 
| Percentage of Patients Who Achieved Remission After 8 Weeks of Treatment Using CGI-S <= 2 | The CGI-S provides the clinician's impression of the patient's current state of mental illness. The clinician uses his or her clinical experience of this patient population to rate the severity of the patient's current mental illness on a 7-point scale ranging from 1 (Normal - not at all ill) to 7 (among the most extremely ill patients). | baseline and 8 weeks | 
| Effect of Escitalopram After 8 Weeks Using Sheehan Disability Scale (SDS) Work | The SDS comprises self-rated items designed to measure impairment. The patient rates the extent to which his or her (1) work, (2) social life or leisure activities and (3) home life or family responsibilities are impaired on a 10-point visual analogue scale, on which 0 = normal functioning and 10 = severe functional impairment. | baseline and 8 weeks | 
| Effect of Escitalopram After 8 Weeks Using Sheehan Disability Scale (SDS) Family | The SDS comprises self-rated items designed to measure impairment. The patient rates the extent to which his or her (1) work, (2) social life or leisure activities and (3) home life or family responsibilities are impaired on a 10-point visual analogue scale, on which 0 = normal functioning and 10 = severe functional impairment. | baseline and 8 weeks | 
| Effect of Escitalopram After 8 Weeks Using Sheehan Disability Scale (SDS) Social | The SDS comprises self-rated items designed to measure impairment. The patient rates the extent to which his or her (1) work, (2) social life or leisure activities and (3) home life or family responsibilities are impaired on a 10-point visual analogue scale, on which 0 = normal functioning and 10 = severe functional impairment. | baseline and 8 weeks | 
| Percentage of Patients Who Responded According to >= 50% Improvement From Baseline to Week 8 in HAMA Total Score | The HAMA is a 14-item rating scale designed to assess global anxiety symptoms. Each symptom is rated from 0 (absent) to 4 (severe). The total score of the 14 items ranges from 0 to 56. | baseline and 8 weeks |
