Inclusion criteria

Inclusion criteria: Inpatients with a moderate or severe depressive episode (HAMD-21 = 14)

Exclusion criteria

Exclusion criteria: Pregnant or lactating women; drug or alcohol addiction; depressive episode secondary to a somatic/neurological disorders or to substance addiction; severe neurological or somatic comorbid condition potentially affecting the study outcome (e.g., dementia, Morbus Cushing)

Design outcomes

Primary

MeasureTime frame
Percent change in depression severity after 8 weeks of antidepressant treatment (T8) as evaluated with the 21-item version of the Hamilton Rating Scale for Depression (HAM-D) with respect to depression severity at study entry (T0). Relative gene expression of ABCB1, FKBP5, P2RX4 and P2RX7 and DNA methylation in CpG-rich regions of these genes will be determined as genomic biomarkers from blood samples at T0 and after six weeks (T6) as predictors of the primary endpoint.

Secondary

MeasureTime frame
Remission state after 8 weeks of antidepressant treatment (T8) as defined by a total score of the 21-item version of the Hamilton Rating Scale for Depression (HAM-D) of equal or less than 9.
