Description of intervention(s) / exposure
Once randomised and on drug, subjects will be dosed with study medication as per local/country standard of care. Therefore, the length of treatment will differ and is based on the subjects response.

escitalopram one 10 mg tablet orally once daily (QD)
sertraline one 50 mg orally QD
venlafaxine extended release (XR) one 75 mg orally QD

Outcomes
Primary outcome [1] 3796 0
Composite markers from 165 different assessments/variables will be assessed to identify genetic, brain structure/function and cognitive markers (or combination of markers) which predict acute drug treatment response in MDD. This will be assessed using:

The MINI International Neuropsychatric Interview.
Hamilton Rating of Depression Scale (HAM-D21).
Web based questionnaire (web-Q), including:
Depression, Anxiety and Stress Scale (DASS42).
Neuroticism, Extraversion, and Openness Five Factor Inventory (NEO-FFI).
Emotion Regulation Questionnaire (ERQ).
Satisfaction with Life Scale (SWLS).
Quick Inventory of Depressive Symptomatology (QIDS-SR)
CORE Rating Scale
Columbia Atypical Depression Diagnostic Scale (ADDS)
Visual Analogue Scale for both physical and psychological pain
Clinical Global Impression (CGI)
26-item World Health Organisation Quality of Life Scale Brief Version (The WHOQOL)
Social and Occupational Functioning Assessment Scale (SOFAS)
Self Rated Global measure of the Frequency, Intensity and Burden of Side Effects Rating (FIBSER).

Psychophysiological assessment (including, respiratory rate, sweat rate, EEG and Event Related Potential) and a Cognitive test battery.
Symptom and sub-type assessment.
Full Genetic array analysis.
Structural and functional MRI.
Timepoint [1] 3796 0
Week 8
Secondary outcome [1] 6407 0
To determine whether markers of acute treatment prediction are also predictive of functional outcome over 6-12 months. Using Quick Inventory of Depressive Symptomatology (QIDS) and the Self Rated Global measure of the Frequency, Intensity and Burden of Side Effects Rating (FIBSER).
Timepoint [1] 6407 0
Week 52
