Comparison of antipsychotic dose equivalents for acute bipolar mania and schizophrenia.
    BMJ mental health, 2023, Volume: 26, Issue:1

    Are antipsychotic dose equivalents between acute mania and schizophrenia the same?. Six databases were systematically searched (from inception to 17 September 2022) to identify blinded randomised controlled trials (RCTs) that used a flexible-dose oral antipsychotic drug for patients with acute mania. The mean and SD of the effective dose and the pre-post changes in manic symptoms were extracted. A network meta-analysis (NMA) under a frequentist framework was performed to examine the comparative efficacy between the antipsychotics. A classic mean dose method (sample size weighted) was used to calculate each antipsychotic dose equivalent to 1 mg/day olanzapine for acute mania. The antipsychotic dose equivalents of acute mania were compared with published data for schizophrenia.. We included 42 RCTs which enrolled 11 396 participants with acute mania. The NMA showed that risperidone was superior to olanzapine (reported standardised mean difference: -022, 95% CI -0.41 to -0.02), while brexpiprazole was inferior to olanzapine (standardised mean difference: 0.36, 95% CI 0.08 to 0.64). The dose equivalents to olanzapine (with SD) were 0.68 (0.23) for haloperidol, 0.32 (0.07) for risperidone, 0.60 (0.11) for paliperidone, 8.00 (1.41) for ziprasidone, 41.46 (5.98) for quetiapine, 1.65 (0.32) for aripiprazole, 1.23 (0.20) for asenapine, 0.53 (0.14) for cariprazine and 0.22 (0.03) for brexpiprazole. Compared with the olanzapine dose equivalents for schizophrenia, those of acute mania were higher for quetiapine (p<0.001, 28.5%) and aripiprazole (p<0.001, 17.0%), but lower for haloperidol (p<0.001, -8.1%) and risperidone (p<0.001, -15.8%).. Antipsychotic drugs have been considered first-line treatment for acute mania, warranting specific dose equivalence for scientific and clinical purposes.

Narrative review of the advances in the pharmacotherapeutic management of juvenile-onset schizophrenia.
    Expert opinion on pharmacotherapy, 2023, Volume: 24, Issue:9

    Schizophrenia usually begins with prodromal symptoms in adolescence. In 39% of patients, onset of psychotic symptoms occurs prior to age 19. Advances in the treatment of psychosis with medications over the last decade are reviewed in this paper.. Understanding how to prescribe antipsychotics early in schizophrenia requires an understanding of the pathophysiology of the disease. The current structure of the dopamine hypothesis is reviewed. Risperidone, paliperidone, olanzapine, quetiapine, and aripiprazole have become established treatments prior to 2012. Since 2012, lurasidone (2017) and brexpiprazole (2022) have also been approved. Lurasidone was approved based on placebo-controlled studies, but brexpiprazole has been approved on the bases of open safety trials. In comparative trials, aripiprazole was better tolerated and less likely to cause hyperprolactinemia and metabolic abnormalities.. Antipsychotics can induce adaptive changes in the brain that predispose patients to future problems such as tardive dyskinesia and supersensitivity psychosis. When pathophysiology of schizophrenia, and a clear understanding of the pharmacology of existing antipsychotics are included in the evidence-based analysis, use of partial agonists, which are less likely to induce adaptive changes in the brain and less likely to induce metabolic and prolactin side effects, become the preferred agents.

Comparative efficacy and safety of 4 atypical antipsychotics augmentation treatment for major depressive disorder in adults: A systematic review and network meta-analysis.
    Medicine, 2023, Sep-22, Volume: 102, Issue:38

    Atypical antipsychotic (AAP) augmentation is an alternative strategy for patients with major depressive disorder (MDD) who had an inadequate response to antidepressant therapy (ADT). We aimed to compare and rank the efficacy and safety of 4 AAPs in the adjuvant treatment of MDD.. We searched randomized controlled trials (RCTs) published and unpublished from the date of databases and clinical trial websites inception to April 30, 2023. The evidence risk of bias (RoB) and certainty are assessed using the Cochrane bias risk tool and grading of recommendations assessment, development, and evaluation (GRADE) framework, respectively. Using network meta-analysis, we estimated summary risk ratios (RRs) or standardized mean difference (SMD) based on the random effects model.. 56 eligible studies comprising 11448 participants were included. In terms of primary efficacy outcome, compared with placebo (PBO), all AAPs had significant efficacy (SMD = -0.40; 95% CI, -0.68 to -0.12 for quetiapine (QTP); -0.35, -0.59 to -0.11 for olanzapine (OLA); -0.28, -0.47 to -0.09 for aripiprazole (ARI) and -0.25, -0.42 to -0.07 for brexpiprazole (BRE), respectively). In terms of acceptability, no significant difference was found, either agents versus agents or agents versus PBO. In terms of tolerability, compared with the PBO, QTP (RR = 0.24; 95% CI,0.11-0.53), OLA (0.30,0.10-0.55), ARI (0.39,0.22-0.69), and BRE (0.37,0.18-0.75) were significantly less well tolerated. 8 (14.2%) of 56 trials were assessed as low RoB, 38 (67.9%) trials had moderate RoB, and 10 (17.9%) had high RoB; By the GRADE, the certainty of most evidence was low or very low.. Adjuvant AAPs had significant efficacy compared with PBO, but treatment decisions must be made to balance the risks and benefits.

Dose-Response Meta-Analysis of Antipsychotic Drugs for Acute Schizophrenia.
    The American journal of psychiatry, 2020, 04-01, Volume: 177, Issue:4

    The dose-response relationships of antipsychotic drugs for schizophrenia are not well defined, but such information would be important for decision making by clinicians. The authors sought to fill this gap by conducting dose-response meta-analyses.. A search of multiple electronic databases (through November 2018) was conducted for all placebo-controlled dose-finding studies for 20 second-generation antipsychotic drugs and haloperidol (oral and long-acting injectable, LAI) in people with acute schizophrenia symptoms. Dose-response curves were constructed with random-effects dose-response meta-analyses and a spline model. The outcome measure was total score reduction from baseline on the Positive and Negative Syndrome Scale or the Brief Psychiatric Rating Scale. The authors identified 95% effective doses, explored whether higher or lower doses than the currently licensed ones might be more appropriate, and derived dose equivalencies from the 95% effective doses.. Sixty-eight studies met the inclusion criteria. The 95% effective doses and the doses equivalent to 1 mg of oral risperidone, respectively, were as follows: amisulpride for patients with positive symptoms, 537 mg/day and 85.8 mg; aripiprazole, 11.5 mg/day and 1.8 mg; aripiprazole LAI (lauroxil), 463 mg every 4 weeks and 264 mg; asenapine, 15.0 mg/day and 2.4 mg; brexpiprazole, 3.36 mg/day and 0.54 mg; haloperidol, 6.3 mg/day and 1.01 mg; iloperidone, 20.13 mg/day and 3.2 mg; lurasidone, 147 mg/day and 23.5 mg; olanzapine, 15.2 mg/day and 2.4 mg; olanzapine LAI, 277 mg every 2 weeks and 3.2 mg; paliperidone, 13.4 mg/day and 2.1 mg; paliperidone LAI, 120 mg every 4 weeks and 1.53 mg; quetiapine, 482 mg/day and 77 mg; risperidone, 6.3 mg/day and 1 mg; risperidone LAI, 36.6 mg every 2 weeks and 0.42 mg; sertindole, 22.5 mg/day and 3.6 mg; and ziprasidone, 186 mg/day and 30 mg. For amisulpride and olanzapine, specific data for patients with predominant negative symptoms were available. The authors have made available on their web site a spreadsheet with this method and other updated methods that can be used to estimate dose equivalencies in practice.. In chronic schizophrenia patients with acute exacerbations, doses higher than the identified 95% effective doses may on average not provide more efficacy. For some drugs, higher than currently licensed doses might be tested in further trials, because their dose-response curves did not plateau.

Efficacy and safety of brexpiprazole in acute management of psychiatric disorders: a meta-analysis of randomized controlled trials.
    International clinical psychopharmacology, 2020, Volume: 35, Issue:3

    Brexpiprazole is a new atypical antipsychotic for schizophrenia management and as adjunct in major depressive disorder (MDD). We searched randomized controlled trials (RCT) to review brexpiprazole efficacy and tolerability in acute management of schizophrenia and MDD using PubMed, EUDRACT, ClinicalTrials.gov and Cochrane Central Register of Controlled Trials. A meta-analysis was conducted using the identified 14 RCT to assess its efficacy using positive and negative syndrome scale (PANSS), clinical global impressions - severity of illness (CGI-S), personal and social performance scale (PSP), Montgomery-Åsberg depression rating scale (MADRS), Sheehan disability scale (SDS) and Hamilton depression rating scale (HDRS17). The mean difference comparing brexpiprazole and placebo were PANSS -4.48, CGI-S -0.23 and PSP 3.24 favoring brexpiprazole. Compared to aripiprazole and quetiapine, brexpiprazole showed similar efficacy. In MDD, brexpiprazole showed efficacy compared to placebo demonstrated by MADRS -1.25, SDS -0.37 and HDRS17 -1.28. Brexpiprazole was associated with side effects including akathisia risk ratio (RR) = 1.72; weight increase RR = 2.74 and somnolence RR = 1.87. Compared to 4 mg, brexpiprazole 2 mg was associated with less risk of akathisia and somnolence. Brexpiprazole demonstrated significant improvements in schizophrenia and MDD and is well-tolerated; however, associated with akathisia and somnolence. These findings will guide psychiatrists and pharmacists in their clinical role for supporting psychiatric patients care.

Efficacy and safety of flexibly dosed brexpiprazole for the adjunctive treatment of major depressive disorder: a randomized, active-referenced, placebo-controlled study.
    Current medical research and opinion, 2018, Volume: 34, Issue:4

    To assess the efficacy, safety, and tolerability of brexpiprazole as adjunctive treatment in adults with major depressive disorder (MDD) and an inadequate response to prior antidepressant treatment (ADT).. Patients with a current major depressive episode after prior treatment with 1-3 ADTs entered an 8- or 10-week prospective treatment phase in which they received double-blind placebo adjunct to open-label ADT. Inadequate responders were randomized (2:2:1) to brexpiprazole 2-3 mg/day, placebo, or quetiapine extended-release (XR) 150-300 mg/day, adjunct to the same ADT, for 6 weeks. The primary efficacy endpoint was the change from baseline (randomization) to week 6 in Montgomery-Åsberg Depression Rating Scale (MADRS) total score. The key secondary efficacy endpoint was the change in Sheehan Disability Scale (SDS) mean score.. Adjunctive brexpiprazole showed a greater improvement in MADRS total score than adjunctive placebo (least squares mean difference [95% confidence interval] = -1.48 [-2.56, -0.39]; p = .0078), whereas adjunctive quetiapine XR did not separate from placebo (-0.30 [-1.63, 1.04]; p = .66). Adjunctive brexpiprazole failed to separate from placebo on the SDS mean score (-0.23 [-0.52, 0.07]; p = .13), but did improve functioning on two of the three SDS items (family life and social life). The most frequent treatment-emergent adverse events in patients receiving brexpiprazole were akathisia (6.1%), somnolence (5.6%), and headache (5.6%).. Adjunctive brexpiprazole 2-3 mg/day improved symptoms of depression compared with adjunctive placebo in patients with MDD and an inadequate response to ADTs, and was well tolerated with no unexpected side effects.

Switching from Inadequate Adjunctive or Combination Treatment Options to Brexpiprazole Adjunctive to Antidepressant: An Open-Label Study on the Effects on Depressive Symptoms and Cognitive and Physical Functioning.
    The international journal of neuropsychopharmacology, 2017, 01-01, Volume: 20, Issue:1

    Approximately 50% of patients with major depressive disorder do not respond adequately to their antidepressant treatment, underscoring the need for more effective treatment options. The objective of this study was to investigate the effect of adjunctive brexpiprazole on depressive symptoms in patients with major depressive disorder who were not responding to adjunctive or combination therapy of their current antidepressant treatments with several different classes of agents (NCT02012218).. In this 6-week, open-label, phase 3b study, patients with major depressive disorder who had an inadequate response to ≥1 adjunctive or combination therapy, in addition to history of ≥1 failure to monotherapy antidepressant treatment, were switched to adjunctive brexpiprazole. Efficacy was assessed by change from baseline to week 6 in Montgomery-Åsberg Depression Rating Scale total score. Patient functioning was assessed using the Sheehan Disability Scale and the Cognitive and Physical Functioning Questionnaire. Safety and tolerability were also assessed.. A total of 51/61 (83.6%) patients completed 6 weeks of treatment with adjunctive brexpiprazole. Improvements in depressive symptoms were observed (least squares mean change from baseline to week 6 in Montgomery-Åsberg Depression Rating Scale total score, -17.3 [P < .0001]) as well as improvements in general and cognitive functioning (mean changes from baseline to week 6: Sheehan Disability Scale, -3.1 [P < .0001]; Massachusetts General Hospital-Cognitive and Physical Functioning Questionnaire, -9.2 [P < .0001]). The most common adverse event was fatigue (14.8%); akathisia was reported by 8.2% of patients.. In patients with major depressive disorder who had switched to open-label adjunctive brexpiprazole following inadequate response to previous adjunctive or combination therapy, improvements were observed in depressive symptoms, general functioning, cognitive function, and energy/alertness.

Effects of Atypical Antipsychotics, Clozapine, Quetiapine and Brexpiprazole on Astroglial Transmission Associated with Connexin43.
    International journal of molecular sciences, 2021, May-25, Volume: 22, Issue:11

    Recently, accumulating preclinical findings suggest the possibility that functional abnormalities of tripartite synaptic transmission play important roles in the pathophysiology of schizophrenia and affective disorder. Therefore, to explore the novel mechanisms of mood-stabilizing effects associated with tripartite synaptic transmission, the present study determined the effects of mood-stabilizing antipsychotics, clozapine (CLZ), quetiapine (QTP) and brexpiprazole (BPZ), on the astroglial l-glutamate release and expression of connexin43 (Cx43) in the astroglial plasma membrane using cortical primary cultured astrocytes. Neither acute (for 120 min) nor subchronic (for 7 days) administrations of CLZ, QTP and BPZ affected basal astroglial l-glutamate release, whereas both acute and subchronic administration of CLZ, QTP and BPZ concentration-dependently enhanced astroglial l-glutamate release through activated hemichannels. Subchronic administration of therapeutic-relevant concentration of valproate (VPA), a histone deacetylase inhibiting mood-stabilizing antiepileptic drug, enhanced the stimulatory effects of therapeutic-relevant concentration of CLZ, QTP and BPZ on astroglial l-glutamate release through activated hemichannel. Subchronic administration of therapeutic-relevant concentration of CLZ, QTP and BPZ did not affect Cx43 protein expression in the plasma membrane during resting stage. After subchronic administration of VPA, acute and subchronic administration of therapeutic-relevant concentrations of CLZ increased Cx43 protein expression in the plasma membrane. Both acute administrations of therapeutic-relevant concentrations of QTP and BPZ did not affect, but subchronic administrations enhanced Cx43 protein expression in the astroglial plasma membrane. Furthermore, protein kinase B (Akt) inhibitor suppressed the stimulatory effects of CLZ and QTP, but did not affect Cx43 protein expression in the astroglial plasma membrane. These results suggest that three mood-stabilizing atypical antipsychotics, CLZ, QTP and BPZ enhance tripartite synaptic glutamatergic transmission due to enhancement of astroglial Cx43 containing hemichannel activities; however, the Cx43 activating mechanisms of these three mood-stabilizing antipsychotics were not identical. The enhanced astroglial glutamatergic transmission induced by CLZ, QTP and BPZ is, at least partially, involved in the actions of these three mood-stabilizing antipsychotics.

Health Care Cost in Patients With Schizophrenia Treated With Brexpiprazole Versus Other Oral Atypical Antipsychotic Therapy.
    Clinical therapeutics, 2020, Volume: 42, Issue:1

    Brexpiprazole is an oral atypical antipsychotic (OAA) for the treatment of schizophrenia (SCZ). This study compared all-cause and psychiatric inpatient hospitalization and medical costs in adult patients with SCZ newly treated with brexpiprazole versus other US Food and Drug Administration-approved OAAs in a real-world setting.. This retrospective cohort study analyzed data from: (1) the IBM MarketScan Commercial and Medicare Supplemental databases, and the MarketScan Multi-State Medicaid database; and (2) the de-identified Optum Clinformatics Datamart. Adult patients were identified if they had SCZ and initiated either brexpiprazole or another OAA during the study identification period (July 1, 2015, to September 30, 2016, for MarketScan Commercial and Medicare Supplemental and for Optum; July 1, 2015, to June 30, 2016, for MarketScan Multi-State Medicaid) and had ≥12 months of continuous enrollment before (baseline) and after (follow-up) the first treatment date. Linear regression analyses were performed to test associations between treatment groups (brexpiprazole vs another OAA) and costs (total and medical); negative binomial regression models were used to estimate number of hospitalizations per year, adjusting for baseline characteristics and medication adherence to index treatment during the 12-month follow-up.. The final study sample consisted of 6254 patients with SCZ: 176 initiated brexpiprazole; 391, ziprasidone; 453, paliperidone; 523, lurasidone; 786, aripiprazole; 1234, quetiapine; 1264, olanzapine; and 1427, risperidone. Controlling for baseline characteristics and medication adherence, the adjusted number of hospitalizations (both all-cause and psychiatric), all-cause total costs, and all-cause medical costs did not differ across groups. Brexpiprazole users had the lowest mean psychiatric costs among all OAA users ($12,013; 95% bootstrap CI, 7488-16,538). Compared with brexpiprazole users, paliperidone (incidence rate ratio [95% CI], 1.52 [1.05-2.19]; P = 0.027) and quetiapine (incidence rate ratio [95% CI], 1.47 [1.04-2.07]; P = 0.029) users had more psychiatric hospitalizations per year. Paliperidone had higher psychiatric costs than brexpiprazole (total, $32,066 [95% bootstrap CI, 28,779-35,353] vs $23,851 [18,907-28,795]; medical, $19,343 [16,294-22,392] vs $12,013 [7488-16,538]). Psychiatric medical costs were also $6744 higher in olanzapine users (95% bootstrap CI, 1694-11,795; P = 0.009) than in brexpiprazole users.. Patients with SCZ treated with brexpiprazole had fewer psychiatric hospitalizations and lower psychiatric costs than those treated with paliperidone. Differences in the number of all-cause hospitalizations and medical costs among treatments were not statistically significant. Although treatment decisions are driven by a number of factors (eg, clinical circumstances and drug costs), choice of OAA may affect health care costs.

Medication Adherence, Health Care Utilization, and Costs in Patients With Major Depressive Disorder Initiating Adjunctive Atypical Antipsychotic Treatment.
    Clinical therapeutics, 2019, Volume: 41, Issue:2

    The purpose of this study was to compare medication adherence, health care utilization, and cost among patients receiving adjunctive treatment for major depressive disorder (MDD) with brexpiprazole, quetiapine, or lurasidone.. Using Truven Health MarketScan® Commercial, Medicaid, and Medicare Supplemental Databases, we identified adults with MDD initiating adjunctive treatment with brexpiprazole, quetiapine, or lurasidone (index atypical antipsychotic [AAP]). We compared medication adherence and persistence measured by proportion of days covered (PDC) and treatment duration of index AAP, all-cause and psychiatric hospital care (hospitalization or emergency department visit), and medical costs during 6-month follow-up. Models performed included logistic regression for hospital care, linear regression for PDC and cost, and Cox proportional hazards regression for time to discontinuation, adjusting for demographic, clinical, and utilization differences during the 6 months before index AAP.. The total sample included 778 brexpiprazole, 626 lurasidone, and 3458 quetiapine therapy initiators. Adjusting for baseline differences, the risk of discontinuation of index AAP was statistically significantly higher for quetiapine than for brexpiprazole (hazard ratio [HR] = 1.13; 95% CI, 1.02-1.25; P = 0.023) and did not differ between lurasidone and brexipiprazole (HR = 1.14; 95% CI, 1.00-1.29; P = 0.054). The adjusted rate of all-cause hospitalization or emergency department visit in the postindex period was lowest for brexpiprazole at 27.4% (95% CI, 24.0%-31.0%), compared with 31.1% (95% CI, 27.3%-35.2%) for lurasidone and 35.3% (95% CI, 33.5%-37.1%) for quetiapine (P< 0.001 for all comparisons). Quetiapine users had increased all-cause costs compared with brexpiprazole users (estimate = $2309; 95% CI, $31-$4587; P = 0.047); all-cause medical costs did not differ between lurasidone and brexpiprazole (estimate = $913; 95% CI, $-2033 -$3859; P = 0.543). Adjusted psychiatric hospital care, psychiatric costs, and PDC did not differ significantly among the groups.. In patients with MDD and a variety of insurance types, brexpiprazole use was associated with statistically significantly lower risks of discontinuation, risk of hospital care (hospitalization and ED visits), and all-cause medical costs compared with adjunctive quetiapine. Differences between brexpiprazole and lurasidone were not statistically significant. These findings suggest that drug choice is associated with subsequent health care utilization and costs.

Activating and Sedating Properties of Medications Used for the Treatment of Major Depressive Disorder and Their Effect on Patient Functioning.
    The Journal of clinical psychiatry, 2019, 04-30, Volume: 80, Issue:3

    Although the sedative and extrapyramidal side effects associated with first-generation antipsychotics are well known, some second-generation antipsychotics are also associated with substantial sedation and activation effects. In this Academic Highlights article, 4 experts on depression from the fields of psychiatry and primary care take a closer look at activation and sedation effects of atypical antipsychotics in patients with MDD. They examine the likelihood of each agent to cause these effects; the impact of these effects on patient functioning, quality of life, and treatment adherence; and the question of whether leveraging activation and sedation to address acute symptoms is ever advisable.

Changes in healthcare resource use and costs associated with early versus delayed initiation of atypical antipsychotic adjunctive treatment in major depressive disorder.
    Journal of medical economics, 2018, Volume: 21, Issue:9

    The study compared all-cause and major depressive disorder (MDD)-related healthcare resource use (HRU) and costs in patients with MDD treated with atypical antipsychotic (AAP) adjunctive therapy early or later in treatment.. Adults with MDD and antidepressant treatment (ADT) who newly initiated adjunctive aripiprazole, brexpiprazole, lurasidone, or quetiapine between October 1, 2014 and September 30, 2015 were identified in the IQVIA Real-World Data Adjudicated Claims database; the index date was the date of the first AAP claim. Patients were stratified into three cohorts: AAP initiated in the first year (Y1); in the second year (Y2); and more than 2 years (Y3) of first ADT use. Within each cohort, HRU and costs were compared between the 12 months before and after the index date. Pre-post changes in HRU and costs were then compared between cohorts.. Five hundred and six (36.7%) patients were categorized as Y1; 252 (18.3%) as Y2; and 622 (45.1%) as Y3. AAP use was associated with significantly decreased rates of all-cause and MDD-related hospitalization and emergency department visits, and increased rates of pharmacy fills and physician office visits; and the magnitude of changes was largest in cohort Y1. Cohort Y1 had the largest reductions in mean (±SD) all-cause medical costs per patient (-$10,496 ± $85,022, p = .015) compared to Y2 (-$2,474 ± $85,022, p = .572) and Y3 (-$472 ± $31,334, p = .823), mainly due to the reduction in hospitalization. After adjusting for differences in baseline characteristics, the largest reductions in hospitalization and medical costs were observed in cohort Y1. Similar increases in all-cause pharmacy costs were seen in all cohorts. A similar trend in costs was observed in MDD-related healthcare services.. AAP treatment was associated with reductions in all-cause and MDD-related medical costs, primarily in decreased hospitalization. The reductions were largest among patients who initiated treatment in the first year.

Cost-effectiveness of brexpiprazole adjunctive treatment for major depressive disorder.
    Journal of affective disorders, 2017, Jan-01, Volume: 207

    Major depressive disorder (MDD) is a debilitating psychiatric illness with a high cost burden. This analysis evaluates the cost-effectiveness of adjunctive brexpiprazole versus comparator branded adjunctive treatment for MDD and background antidepressant therapy (ADT) alone from a US payer perspective.. An economic model was developed to assess the cost-effectiveness of brexpiprazole versus comparator adjunctive treatment and ADT alone on total direct medical costs using a 6-week cycle time frame for a total of 48 weeks, with treatment response and remission as primary outcomes. The model consisted of 3 parts, 1 to represent the acute treatment phase and 2 to represent the maintenance stage.. In the base-case analysis, brexpiprazole as reference treatment resulted in cost per additional responder ranging from $19,442-$48,745 and cost per additional remitter ranging from $27,196-$71,839 versus comparator treatments over 48 weeks. Sensitivity analyses showed treatment with brexpiprazole was more costly, but more clinically effective in all probabilistic simulations.. This representation of disease natural history over 48 weeks may not account for all possible health states. Resource utilization on treatment was estimated using the resource use data from previous trials, and may overestimate medical costs compared to the real-world setting. Treatment comparators were limited to branded therapies, and head-to-head studies were not available to obtain data inputs.. Compared to other branded adjunctive therapies, brexpiprazole increases response and remission at 6 weeks; medical care cost savings were observed with the use of brexpiprazole. These findings may assist clinicians and formulary decision makers when selecting treatment for MDD.
