Sertraline Versus Escitalopram in South Asian Participants With Moderate to Severe Major Depressive Disorder

Study Overview
=================
Brief Summary
-----------------
Objective: The aim of this randomized controlled trial was to compare the efficacy and safety of sertraline and escitalopram in participants with moderate to severe major depressive disorder (MDD). Methods: A total of 744 participants with moderate to severe MDD were randomly assigned to receive either sertraline or escitalopram for 8 weeks. Drug dosages and titration schedules were based on the recommendations of the prescribing information for each product and according to the judgment of the clinicians involved in the study. The primary outcome measures were changes from baseline on the Montgomery-Åsberg Depression Rating Scale (MADRS) and the Clinical Global Impression (CGI) scale as well as frequency of adverse events in both groups.

Detailed Description
-----------------
This is a monocentric, double-blind, parallel, randomized controlled trial conducted in Khan Research Laboratories (KRL) hospital, Islamabad, Pakistan for a total period of 16 weeks. By employing appropriate measures to ensure adequate allocation concealment, thereby minimizing the potential for selection bias in the assignment of participants to treatment groups, the investigators studied if there was any significant difference in in efficacy and tolerability of oral sertraline (50 - 200 mg/day) and oral escitalopram (10 mg/day) given either at night or during the day in the South Asian population for the treatment of moderate to severe major depressive disorder (MDD). 744 South Asian patients with moderate to severe MDD as per the Montgomery-Asberg Depression Rating Scale (MADRS) scale who had consented to participate in the trial and who fulfilled the inclusion criteria were included in our study. The study was conducted at KRL hospital.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in clinical global impression (CGI) scale | Change in the clinical global impression scale. CGI is rated on a 7-point scale, with the severity of illness scale using a range of responses from 1 (normal) through to 7 (amongst the most severely ill) | 4 months | 
| Change in Montgomery-Åsberg Depression Rating Scale (MADRS) scale | Change in Montgomery-Åsberg Depression Rating Scale from baseline. The MADRS (Montgomery & Åsberg, 1979) comprises the following 10 items: apparent sadness; reported sadness; inner tension; reduced sleep; reduced appetite; concentration difficulties; lassitude; inability to feel; pessimistic thoughts; and suicidal thoughts. Clinicians rate each item on a 7-point Likert scale; the sum of the item scores produces a MADRS total score that ranges from 0 to 60, with higher scores reflecting greater depression severity. | 4 months | 
| Diarrhea | Number of participants with diarrhea | 4 months | 
| Nausea | Number of participants with nausea | 4 months | 
| Sexual dysfunction | Number of participants with sexual dysfunction | 4 months | 
| Upper respiratory tract infection | Number of participants with upper respiratory tract infection | 4 months |
