A Double-Blind, Placebo-Controlled Study of Brexpiprazole in the Treatment of Borderline Personality Disorder.
The primary objective of the proposed study is to evaluate the safety and efficacy of Brexpiprazole in adults with borderline personality disorder (BPD). The hypothesis to be tested is that brexpiprazole will be more effective and well tolerated in adults with BPD compared to placebo. The proposed study will provide needed data on the treatment of a disabling disorder.
Dysfunctions in the serotoninergic and dopaminergic systems have been demonstrated in—and considered as possible causes for—symptoms associated with the disorder (25-28). Several studies on the use of traditional (29) and atypical antipsychotic agents in patients with borderline personality disorder (30-31) have shown a positive effect on individual symptoms (29, 32-36). However, we are not aware of any study evaluating Brexpiprazole in the treatment of patients with borderline personality disorder. In the proposed double-blind, placebo-controlled study, the influence of Brexpiprazole on the multifaceted psychopathological symptoms and aggression of patients with borderline personality disorder will be investigated.
Brexpiprazole therefore has distinctive properties that make it a promising option for patients with BPD. Brexpiprazole is a novel D2 partial agonist, has affinity for 5-HT1A, acts as an antagonist of the noradrenergic α1/2 receptor, partial agonist for D3, and antagonist for 5-HT2A (37-39). In addition, because of low rates of side effects, Brexpiprazole should be a well-tolerated and in fact desired medication approach to BPD.
