Primary
| Measure | Time frame |
|---|---|
| Main Objective: The primary goal of the study is to investigate the effects of add-on treatment with the TSPO ligand etifoxine in addition to TAU on clinical symptoms in patients suffering from unipolar/bipolar depressive disorder. Clinical symptoms will be assessed by the grade of depression using the Hamilton Scale for Depression (HAMD-21) several times up to day 15 of treatment. Does add-on treatment with the TSPO ligand etifoxine for 14 days accelerate (reduction of ET50) the response compared to add-on treatment with placebo in addition to TAU?;Secondary Objective: Does add-on treatment with the TSPO ligand etifoxine in depressive patients compared to add-on treatment with placebo in addition to TAU lead to: - an increased treatment response (increase of Emax parameter)? - a reduction of the HAM-D score on day 15? - altered synthesis of neurosteroids, TSPO Expression and/or acitivty of the HPA axis? - altered cognitive functions like memory or emotional processing assessed by a neuropsychological test battery? - changes of functional neuronal networks and cognitive functions assessed using functional magnetic resonance imaging (fMRI) by using resting-state measurements and task-based paradigms? - changes of microbiome composition? - changes of odour capacity? - does cessation of intake of the TSPO ligand lead to a relapse or withdrawal symptoms? ;Primary end point(s): ET50 estimated based on the HAMD-21 scores assessed at the baseline and days 1, 2, 3, 4, 5, 6, 7, 8, 15, 22 and 29 after start of the treatment;Timepoint(s) of evaluation of this end point: A total number of 50 data sets has been obtained. | — |
