E.2.1 | Main objective of the trial |

|
E.2.2 | Secondary objectives of the trial |
1) Efficacy:
A- To show maintenance of a significant effect of buprenorphine on suicidal ideas, on psychological pain and a mediating effect of psychological pain

D- To determine the treatment arm with the lowest number of discontinuations for inefficiency according to the patient
E- To determine the number of suicide attempts or completed suicides during follow-up
2) Tolerance:
A- To determine the dose of buprenorphine with the best tolerance profile from D0 to D14 and the frequency of withdrawal symptoms from D14 to D21 for each dose.
3) Mechanisms:
To determine the physiological mechanisms of psychological pain and suicidal ideation, response to buprenorphine treatment in terms of:
A- Neuropsychological processes.
B. Brain processes.
C- To create a biobank

C- Déterminer l’effet de la buprénorphine sur les symptômes de dépression (hors idées suicidaires et douleur psychologique).
D- Déterminer quel est le bras de traitement ayant le plus faible nombre d’arrêts de traitement expérimental pour cause d’inefficacité selon le patient
E- Déterminer le nombre de tentatives de suicide ou suicides aboutis durant le suivi
2) Tolérance:
A- Déterminer la dose de buprénorphine ayant le meilleur profil de tolérance de J0 à J14.
B- Déterminer la fréquence des symptômes de sevrage pour chaque dose.
3) Processus impliqués:
Pour déterminer les mécanismes physiologiques de la douleur psychologique et de l’idéation suicidaire, la réponse au traitement buprénorphine en termes de :
