Abstract
Background and objective: Inadequate response to antidepressant monotherapy is common among patients with major depressive disorder (MDD). The efficacy and safety of adjunctive brexpiprazole 2 mg/day has recently been confirmed during the 6-week, randomized, placebo-controlled phase 2/3 (BLESS) study, which evaluated brexpiprazole at 1 mg/day and 2 mg/day versus placebo as adjunctive therapy to antidepressant therapies in 740 Japanese patients with MDD and an inadequate response to antidepressant monotherapy. This study evaluated the long-term safety and efficacy of adjunctive fixed-dose brexpiprazole 2 mg/day in Japanese patients with MDD.
Methods: An open-label, 52-week study enrolled rollover patients who completed the 6-week, double-blind, randomized, placebo-controlled phase 2/3 BLESS study (NCT03697603), and de novo patients aged ≥ 65 years. Patients were titrated to fixed-dose brexpiprazole 2 mg/day from Week 1. Safety assessments included treatment-emergent adverse events (TEAEs; primary outcome) and clinical and laboratory variables. Efficacy was assessed using the Montgomery-Åsberg Depression Rating Scale (MADRS), Clinical Global Impression-Improvement (CGI-I) scale, Hamilton Depression Rating Scale (HAM-D) 17-item total score, and Sheehan Disability Scale (SDS) score.
Results: In total, 247 patients [rollover, n = 216; de novo (previously unexposed), n = 31] were included in the safety/efficacy populations, and 138 (rollover, n = 132; de novo, n = 6; 55.9%) completed the study. Common TEAEs (incidence ≥ 10%) were weight gain [33.2% (n = 82)], akathisia [23.5% (n = 58)], nasopharyngitis [21.1% (n = 52)], and somnolence [10.5% (n = 26)]. TEAEs leading to treatment discontinuation occurred in 26.7% of patients receiving brexpiprazole and 58.1% of de novo patients. The mean (SD) increase in body weight from baseline to Week 52 [observed cases (OC)] was 4.2 (6.5) kg (n = 138); 44.5% (n = 110) had weight gain ≥ 7% at any postbaseline visit. There were no cases of tardive dyskinesia and no AEs related to suicide/suicide attempts. One death occurred (unknown cause), which was unrelated to study treatment. Improvements in the MADRS total score were observed from baseline over the course of the 52-week study [mean (SD) change at Week 52 (OC): - 7.3 (8.7)] for all patients receiving brexpiprazole. The overall MADRS response rate and remission rate in patients receiving brexpiprazole was 41.3% (n = 57) and 34.8% (n = 48), respectively, at Week 52 (OC). Improvements in CGI-S, HAM-D 17 item total score, and SDS mean scores were also observed from baseline over the 52-week study, with a mean (SD) change from baseline at Week 52 (OC) of - 0.8 (1.0), - 5.9 (6.3), and - 1.0 (2.2), respectively, indicating a sustained improvement in symptoms with long-term brexpiprazole treatment.
Conclusions: This is the first study to evaluate the safety profile of brexpiprazole 2 mg/day in Japanese patients with MDD, including older adults, which is similar to previous reports, with no new safety risks, and continued efficacy over 52 weeks.

CNS Drugs promotes rational pharmacotherapy within the disciplines of clinical psychiatry and neurology. The Journal includes:
- Overviews of contentious or emerging issues.
- Comprehensive narrative reviews that provide an authoritative source of information on pharmacological approaches to managing neurological and psychiatric illnesses.
- Systematic reviews that collate empirical evidence to answer a specific research question, using explicit, systematic methods as outlined by the PRISMA statement.
- Adis Drug Reviews of the properties and place in therapy of both newer and established drugs in neurology and psychiatry.
- Original research articles reporting the results of well-designed studies with a strong link to clinical practice, such as clinical pharmacodynamic and pharmacokinetic studies, clinical trials, meta-analyses, outcomes research, and pharmacoeconomic and pharmacoepidemiological studies.
Additional digital features (including animated abstracts, video abstracts, slide decks, audio slides, instructional videos, infographics, podcasts and animations) can be published with articles; these are designed to increase the visibility, readership and educational value of the journal’s content. In addition, articles published in CNS Drugs may be accompanied by plain language summaries to assist readers who have some knowledge of, but not in-depth expertise in, the area to understand important medical advances.
