PSYGEN: Evaluation of the Relevance of Pharmacogenetics in the Prescription Off Antidepressants in a Military Population
Study Details
Study Description
Brief Summary
The treatment of depression, anxiety disorders and post-traumatic stress disorder (PTSD) is a main public health problem due to the frequency of these pathologies and the very partial effectiveness of the existent therapies. These illnesses generally require the prescription of several successive lines of antidepressant treatments before the treatments actually become effective, leading to a several week delay during which the patient suffers from the symptoms of his/her pathology and is also likely to experience the side effects of the treatment.
Pharmacogenetics is an individualized prescribing modality that aims to predict the most favorable treatment for a given individual based on the study of genetic variants of cytochromes.
The main hypothesis of this research is that the use of pharmacogenetics in routine practice in a population of military personnel requiring a first prescription of an antidepressant is of interest to improve the tolerance and effectiveness of the treatment.

Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Prescription with pharmacogenetics assistance The participants randomized in this arm will received a prescription of antidepressants based on the results of pharmacogenetics analyses. |
Biological: Blood collection
A blood sample will be collected at enrollment to perform pharmacogenetics analyses.
Other: Questionnaires
Several questionnaires will be filled by the participants or by the clinicians at every study visits: Hospital anxiety depression scale (HAD), Post Traumatic Stress Disorder Checklist for DSM-5 (PCL-5), Quick inventory of depressive symptomatology - self rated (QiDS), Beck's Anxiety Inventory (BAI), World Health Organization Quality Of Life (WHOQOL-BREF), EuroQol Group questionnaire (EQ5D), Frequency, intensity, burden of side effects rating (FIBSER), Udvalg for Kliniske Undersøgelser - Side Effects Rating Scale - for Patients (UKU-SERS-PAT), Clinical Global impression (CGI), Montgomery and Asberg Depression Rating Scale (MADRS).
Other: Cognitive test battery (optional)
For patients participating in the ELAN ancillary study : the participants will undergo a battery of neurocognitive tests assessing motivation ("élan vital" in French).

Outcome Measures
Primary Outcome Measures
- Proportion of patients with a Frequency, Intensity, and Burden of Side Effects Ratings (FIBSER) scale deleterious score ≤ 2 after 8 weeks of treatment [8 weeks after antidepressant treatment initiation]
This endpoint will allow to assess the clinical tolerance of antidepressant treatment and to compare the results between the 2 arms. The FIBSER scale score ranges from 0 to 18 with higher scores reflecting more deleterious side effects.
