| To evaluate the efficacy of brexpiprazole up to 3 mg/day as adjunctive treatment to paroxetine or sertraline on PTSD symptoms | 
 
| valutare l'efficacia di 1-3 mg/die di brexpiprazolo sui sintomi di DPTS, quale trattamento aggiuntivo a paroxetina o sertralina | 
 
 
 | 
| E.2.2 | Secondary objectives of the trial  | 
- To evaluate the efficacy of brexpiprazole up to 3 mg/day on global clinical impression
 - To evaluate the efficacy of brexpiprazole up to 3 mg/day on sleep quality
 - To evaluate the efficacy of brexpiprazole up to 3 mg/day on depressive and anxiety symptoms
 - To evaluate the efficacy of brexpiprazole up to 3 mg/day on functioning
 - To evaluate the efficacy of brexpiprazole up to 3 mg/day on health-related quality of life
 - To evaluate the safety and tolerability of up to 3 mg/day brexpiprazole
 
 | 
 
valutare l'efficacia di 1-3 mg/die di brexpiprazolo su: 
 
 • impressione clinica globale; 
 • qualità del sonno; 
 • sintomi depressivi e di ansia; 
 • funzioni; 
 • qualità della vita correlata alla salute. 
 
 •valutare la sicurezza e la tollerabilità di 1-3 mg/die di brexpiprazolo

    ANALISI ESPLORATIVA DI FARMACOGENETICA 
 
 
  L’obiettivo è quello di raccogliere e conservare campioni genetici (DNA) per un eventuale studio futuro atto a scoprire se sia possibile utilizzare un gene (o una combinazione di geni) al fine di prevedere la risposta a brexpiprazolo. Inoltre, potrebbe essere condotto uno studio per tentare di individuare i geni che sono correlati a questa indicazione.
