Pharmacological properties

Pharmacodynamics

Mechanism of action

Brexpiprazole is an atypical antipsychotic. The pharmacology of brexpiprazole is thought to be mediated by modulatory activity at the serotonin and dopamine systems, combining partial agonist activity at serotonergic 5-HT1A and dopaminergic D2 receptors with receptor antagonist activity with similar high affinity for all of these receptors (inhibition constant (Ki): 0.1-0.5 nmol). Brexpiprazole also exhibits antagonistic activity at noradrenergic α1b/2c receptors with an affinity in the same subnanomolar Ki range (Ki: 0.2-0.6 nmol).

Pharmacodynamic effects

The effect of genetic variations on the pharmacodynamic response to brexpiprazole has not been studied.

Effect on QT interval

The effect of brexpiprazole on the QT interval was studied in patients with schizophrenia or schizoaffective disorder. In a pooled analysis, brexpiprazole did not cause clinically significant prolongation of the QTc interval after administration at therapeutic and supratherapeutic doses (4 mg/day; n = 62 or 12 mg/day; n = 53), and there was no correlation between brexpiprazole concentrations and QTc prolongation.

Subgroup analyses in the QTc study demonstrated that the QTc prolongation was greater in women than in men. In the brexpiprazole 4 mg/day group, the maximum placebo-adjusted mean change from baseline in QTcl was 5.2 ms (90% CI: 1.5, 8.9) in men (n = 48) and 15.0 ms (90% CI: 7.7, 22.3) in women (n = 14) at 6 hours post-dose. In the brexpiprazole 12 mg/day group, the maximum placebo-adjusted mean change from baseline in QTcl interval was 2.9 ms (90% CI: -1.2, 6.9) in men (n = 40) at 12 hours post-dose and 10.4 ms (90% CI: 2.7, 18.2) in women (n = 13) at 24 hours post-dose. The smaller number of women than men included in the study does not allow for definitive conclusions.

Clinical efficacy and safety

The efficacy and safety of brexpiprazole treatment in adults with schizophrenia were studied in two multinational and one regional (Japan), 6-week, randomized, double-blind, placebo-controlled, fixed-dose clinical trials (Studies 1-3), a multinational, 6-week, randomized, double-blind, placebo-controlled, active reference (quetiapine) flexible-dose clinical trial (Study 4), and one multinational, placebo-controlled, 52-week maintenance treatment trial (Study 5). 2690 patients aged 18-65 years participated in these studies.

In Studies 1, 2, and 3, the dose of brexpiprazole was titrated as described in the Dosage and Administration section: 1 mg for 4 days, then 2 mg on days 5 through 7. On day 8, the dose was increased to 4 mg for some treatment groups.

Short-term studies

In three short-term, fixed-dose studies (Studies 1, 2, and 3), patients were randomized to receive brexpiprazole 2 mg once daily, 4 mg once daily, or placebo.

The key secondary endpoint in Studies 1, 2, and 4 was the Clinical Global Illness Severity Index (CGI-S) for schizophrenia, a 7-point clinician-rated assessment of illness severity. The CGI-S was also assessed in Studies 3 and 5 as a secondary endpoint.

The efficacy of brexpiprazole was also assessed by several pre-specified secondary endpoints; specific aspects of schizophrenia symptoms (PANSS positive subscale score, PANSS negative subscale score, PANSS agitation component score [PES], Marder factors PANSS positive, negative, disorganized thinking, uncontrolled hostility/agitation, anxiety/depression) and response analyses (defined as a 30% improvement from baseline in the PANSS total score or a CGI-1 score of 1 [very much improved] or 2 [much improved]).

Efficacy was demonstrated in Study 1 for both brexpiprazole doses of 2 mg/day and 4 mg/day and was replicated in Study 2 for the brexpiprazole dose of 4 mg/day only and in Study 3 for the brexpiprazole dose of 2 mg/day only.

In flexible-dose study 4, patients in the brexpiprazole group had a numerically greater improvement in the PANSS total score than patients in the placebo group, but the difference did not reach statistical significance at week 6 for the primary efficacy analysis (p = 0.0560; see Table 1). In this study, the active reference drug (quetiapine XR) was added only for sensitivity assessment, separate from placebo.

An unstructured variance-covariance matrix structure was used.

The main analysis was performed using the MMRM model with random imputation for missing data. The results of the sensitivity analysis using placebo-based multiple imputation for missing data (PMI) were consistent with the main analysis.

Results for key secondary outcomes and additional endpoints supported the primary endpoint.

In Study 1, statistically significant greater improvement in the CGI-S score, a key secondary efficacy endpoint, at Week 6 was also demonstrated for the 2 mg/day and 4 mg/day groups compared with the placebo groups. Due to the nature of the testing, the greater improvement in CGI-S demonstrated for the 2 mg/day and 4 mg/day groups can only be considered confirmatory for Studies 2, 3, and 4 (see Table 2).

Research on maintaining effectiveness

In Study 5, a long-term study designed to assess the maintenance of the effect of brexpiprazole by assessing the delay in time to future relapse of schizophrenia, patients with schizophrenia who responded to treatment with brexpiprazole 1-4 mg/day were stabilized for 12-36 weeks and then randomized in a double-blind fashion to continue treatment with a stabilizing dose of brexpiprazole (n = 96) or receive placebo (n = 104) for 52 weeks of analysis or until relapse.

In the primary analysis of time to future relapse, patients treated with brexpiprazole demonstrated a significantly longer time to relapse compared with patients treated with placebo (p < 0.0001). At week 52, brexpiprazole (13.5%) reduced the risk of future relapse by 71% compared with placebo (38.5%). During stabilization, brexpiprazole improved clinical symptom burden (PANSS, CGI-S, and CGJ-I scores [analysis of covariance - ANCOVA, last observation carried forward - LOCF]) and function (Global Assessment of Functional Status (GAF) scale [ANCOVA LOCF]). These improvements were maintained during the 52-week double-blind maintenance phase in patients receiving brexpiprazole, whereas patients randomized to receive placebo experienced worsening in PANSS, CGI-S, CGI-I, and GAF scores [ANCOVA LOCF]). Compared with placebo, brexpiprazole maintained symptom control and function.

Children

The European Medicines Agency has deferred the obligation to submit the results of studies on the efficacy and safety of brexpiprazole in children aged 13 to 18 years (for information on use in children, see section 4.2).

Pharmacokinetics

Absorption

Brexpiprazole is absorbed after tablet administration, reaching peak plasma concentrations 4 hours after a single dose, with an absolute oral bioavailability of 95.1%. Steady-state concentrations of brexpiprazole are achieved within 10-12 days of dosing. Administration of a 4 mg brexpiprazole tablet with a standard high-fat meal had no significant effect on brexpiprazole Cmax or AUC. After single and multiple once-daily dosing, brexpiprazole exposure (Cmax and AUC) increased in a dose-proportional manner. Based on in vivo studies, brexpiprazole is not a substrate or inhibitor of efflux transporters such as multidrug resistance protein (MDR) 1, P-gp, and BCRP.

Distribution

The volume of distribution of brexpiprazole after intravenous administration is high (1.56 L/kg ±
0.418 L/kg), indicating extravascular distribution. Brexpiprazole is highly bound to plasma proteins (greater than 99%), serum albumin and α1-acid glycoprotein, and protein binding is not affected by renal or hepatic impairment. Based on in vitro studies, warfarin, diazepam and digitoxin do not affect protein binding of brexpiprazole.

Biotransformation

At steady state, DM-3411 accounts for 23.1% to 47.7% of the plasma exposure (A and C) of brexpiprazole. It should be noted that preclinical in vivo studies have demonstrated that at clinically relevant plasma exposures of brexpiprazole, brain exposures of DM-3411 were below the limit of detection. Thus, DM-3411 is not considered to contribute to the therapeutic effects of brexpiprazole.

Breeding

Following a single oral dose of [14C]-labeled brexpiprazole, approximately 24.6% and 46% of the administered radioactivity was recovered in the urine and feces, respectively. Less than 1% of unchanged brexpiprazole was recovered in the urine and approximately 14% of the oral dose was recovered unchanged in the feces. The apparent oral clearance of brexpiprazole tablets after once-daily dosing is 19.8 (± 11.4) mL/h/kg. Following multiple once-daily dosing of brexpiprazole, the terminal half-lives of brexpiprazole and its major metabolite DM-3411 are 91.4 hours and 85.7 hours, respectively.

Linearity/nonlinearity

The pharmacokinetics of brexpiprazole are dose-proportional and time-invariant after single (0.2-8 mg) and multiple (0.5-4 mg) once-daily administration.

Pharmacokinetics in special patient populations

Age

Following a single dose of brexpiprazole (2 mg), similar systemic exposure (Cmax and AUC) to brexpiprazole was observed in elderly patients (aged 65 years and older) compared to adult patients (aged 18-45 years; see sections 4.2 and 4.4).

Sex

In a population pharmacokinetic analysis, gender was found to be a statistically significant covariate. The exposure (A and C) of brexpiprazole was estimated to be 25% higher in women than in men (see section 4.8).

Race

Although no specific pharmacokinetic studies have been performed, a population pharmacokinetic analysis did not reveal evidence of clinically significant race-related differences in the pharmacokinetics of brexpiprazole.

CYP2D6 genotype

Population pharmacokinetic analysis demonstrated that in patients with poor CYP2D6 metabolisers, brexpiprazole exposure was 47% higher compared to patients with extensive metabolisers (see section 4.2).

Smoking

In vitro studies using human liver enzymes have shown that brexpiprazole is not a CYP1A2 substrate, therefore smoking does not affect the pharmacokinetics of brexpiprazole.

Kidney dysfunction

In patients (n = 10) with severe renal impairment (creatinine clearance < 30 mL/min), AUC and C of brexpiprazole when administered orally (single dose of 3 mg) increased by 68%, while Cmax did not change compared to healthy volunteers. For patients with moderate or severe renal impairment (creatinine clearance < 60 mL/min), the maximum recommended dose is reduced to 3 mg once daily (see section 4.2).

Liver dysfunction

In patients (n = 22) with varying degrees of hepatic impairment (Child-Pugh classes A, B, and C), the AUC and C of brexpiprazole after oral administration (single dose of 2 mg) were increased by 24% in mild hepatic impairment, 60% in moderate hepatic impairment, and unchanged in severe hepatic impairment compared to matched healthy volunteers. For patients with moderate or severe hepatic impairment (Child-Pugh classes B and C), the maximum recommended dose is reduced to 3 mg once daily (see section 4.2).

Children

The safety and efficacy of brexpiprazole in children and adolescents aged 18 years and above have not been established (see section 4.2).

Preclinical safety data

The effects observed in repeated dose toxicity studies in rats and monkeys were mainly related to the increased pharmacological activity of brexpiprazole. Based on the A and C0-24h, the maximum recommended human dose (MRHD) of 4 mg/day could not be used to derive a safety margin for male and female rats and monkeys.

Cardiovascular toxicity

After oral administration, brexpiprazole reduced blood pressure and prolonged the QT interval in a safety pharmacology study in conscious male dogs, in repeated dose toxicity studies in male and female monkeys, and in a juvenile toxicity study in male and female dogs. The blood pressure-lowering effect of brexpiprazole is associated with the expected blockade of α1-adrenoceptors in peripheral blood vessels.

Genotoxicity, carcinogenicity

Brexpiprazole did not demonstrate any genotoxic potential in in vitro and in vivo studies using clinically relevant exposures. Oral administration of brexpiprazole did not increase the incidence of tumors in a 2-year carcinogenicity study in male and female rats and male mice at exposures 4.4 and 3.1 times the MRDL. In female mice, an increased incidence of adenocarcinoma and adenosquamous carcinoma of the mammary gland and adenomas of the distal pituitary gland were observed at exposures similar to or even lower than clinically relevant exposures, and these prolactin-mediated endocrine tumors have also been observed in rodents given other antipsychotics. The clinical relevance of these findings has not been established.

After oral administration, brexpiprazole did not affect the fertility of male rats, but prolonged diestrus and reduced fertility in female rats at exposure levels similar to or even lower than those achieved clinically at the MRDL. A significant increase in preimplantation loss was observed at exposures 4.1 times the clinical MRDL. In embryofetal developmental toxicity studies, brexpiprazole was not teratogenic in rats when administered orally at exposure levels (based on data in non-pregnant female rats) achieved clinically at the MRDL. In rabbits, vertebral malformations were observed in 3 fetuses from 2 litters at maternally toxic oral doses of brexpiprazole with exposures approximately 16.5 times the clinical exposure at the MRHD.

Growth retardation, mental development and reduced viability of the offspring were observed at maternally toxic doses of brexpiprazole in oral pre-/postnatal developmental toxicity studies in rats.

After oral administration to pregnant rats, brexpiprazole was demonstrated to be transferred to the fetus and into milk at concentrations that were generally comparable to levels in maternal blood.

Indication

Treatment of schizophrenia in adult patients.

Contraindication

Hypersensitivity to the active substance or to any of the excipients.

Hereditary problems of galactose intolerance, total lactase deficiency or glucose-galactose malabsorption.

Children under 18 years of age.

Interaction with other medicinal products and other types of interactions

Brexpiprazole is primarily metabolized by CYP3A4 and CYP2D6.

Potential effects of other drugs on the action of brexpiprazole

SURZA4 inhibitors

Coadministration of ketoconazole (200 mg twice daily for 7 days), a potent CYP3A4 inhibitor, with a single oral dose of 2 mg brexpiprazole resulted in a 97% increase in brexpiprazole AUC and C, but no change in Cmax. Based on the results of interaction studies, it is recommended that the brexpiprazole dosage be adjusted to half the dose when potent CYP3A4 inhibitors (itraconazole, ketoconazole, ritonavir, and clarithromycin) are coadministered.

Inductors SURZA4

Co-administration of rifampicin (600 mg twice daily for 12 days), a potent CYP3A4 inducer, with a single oral dose of 4 mg brexpiprazole resulted in a 31% and 73% decrease in brexpiprazole Cmax and AUC, respectively. When brexpiprazole is co-administered with a potent CYP3A4 inducer (e.g. rifampicin), the total daily dose of brexpiprazole should be increased approximately three-fold compared to the recommended daily dose (see section 4.2). Once-daily dosing with concomitant CYP3A4 inducers results in high peak-to-trough fluctuations, and a split daily dose is preferred.

CYP2D6 inhibitors

When a single oral dose of 2 mg brexpiprazole was co-administered with quinidine (324 mg/day for 7 days), a potent CYP2D6 inhibitor, the AUC and C of brexpiprazole increased by 94%, while Cmax was unchanged. Based on the results of interaction studies, it is recommended that the dosage of brexpiprazole be adjusted to half the dose when co-administered with a potent CYP2D6 inhibitor (quinidine, paroxetine, and fluoxetine).

Based on the results of a population pharmacokinetic analysis, an approximately 4- to 5-fold increase in brexpiprazole concentrations is expected in CYP2D6 extensive metabolisers receiving CYP3A4 and CYP2D6 inhibitors, or in CYP2D6 poor metabolisers receiving a potent CYP3A4 inhibitor, and a four-fold dose reduction is recommended for these patients (see section 4.2).

Potential effect of brexpiprazole on the action of other drugs

In vitro studies indicate that clinically significant pharmacokinetic interactions of brexpiprazole with drugs metabolized by cytochrome P450 enzymes are unlikely. Brexpiprazole does not affect the absorption of drugs that are substrates of the transporters BCRP (breast cancer resistance protein) and P-gp (P-glycoprotein).

Brexpiprazole should be used with caution concomitantly with other drugs that prolong the QT interval or disrupt electrolyte balance.

When brexpiprazole is used concomitantly with drugs that increase creatine phosphokinase (CPK) levels, the possible additive effect of brexpiprazole on CPK elevation should be considered.

Pharmacodynamic interactions

There are currently no data on pharmacodynamic interactions of brexpiprazole. Caution should be exercised when prescribing with other drugs. Given the primary effect of brexpiprazole on the central nervous system (CNS), caution should be exercised when taking alcohol or other drugs that affect the CNS, due to possible cross-adverse reactions, such as sedation (see section "Adverse reactions").

Application features

During treatment with antipsychotics, clinical improvement may take several days to several weeks. Patients should be closely monitored during this period.

The emergence of suicidal behaviour is characteristic of psychotic disorders and mood disorders and has in some cases been observed shortly after initiation or switch to antipsychotic treatment, including brexpiprazole treatment (see section 4.8).

Antipsychotic treatment should be accompanied by close monitoring of high-risk patients.

Cardiovascular disorders

Brexpiprazole has not been studied in patients with a history of myocardial infarction/ischemic heart disease or clinically significant cardiovascular disease, as such patients were not included in clinical trials.

Brexpiprazole should be used with caution in patients with established cardiovascular disease (history of myocardial infarction or ischemic heart disease, heart failure or conduction disturbances), cerebrovascular disease, and conditions predisposing to hypotension (dehydration, hypovolemia, and treatment with antihypertensive drugs) or hypertension (including late-stage or malignant hypertension).

QT prolongation

QT prolongation may occur in patients treated with antipsychotics. Only a few non-serious cases of QT prolongation have been reported in clinical trials with brexpiprazole. Caution should be exercised when prescribing brexpiprazole to patients with established cardiovascular disease, a family history of QT prolongation, electrolyte imbalance, or concomitant use with medicinal products known to prolong the QT interval (see sections 5.1 and 4.8).

Venous thromboembolism

Cases of venous thromboembolism (VTE) have been reported with antipsychotics. Since patients treated with antipsychotics often have risk factors for VTE, all possible risk factors for VTE should be identified before and during treatment with brexpiprazole and preventive measures should be taken.

Orthostatic hypotension and syncope

Adverse reactions associated with orthostatic hypotension may include dizziness, syncope, and tachycardia. These risks are generally higher at the beginning of antipsychotic treatment and during dose increases. Patients at increased risk of these adverse reactions (e.g. elderly patients) or at increased risk of developing complications of hypotension include those with dehydration, hypovolemia, treatment with antihypertensive drugs, history of cardiovascular disease (e.g. heart failure, myocardial infarction, ischemia or conduction disorders), history of cerebrovascular disease, and patients who have not previously received antipsychotics. In such patients, a lower initial dose should be used with slower titration and orthostatic vital signs should be monitored (see section "Method of administration and dosage").

Neuroleptic malignant syndrome (NMS)

A potentially fatal symptom complex called neuroleptic malignant syndrome (NMS) has been reported in association with antipsychotic treatment, including brexpiprazole (see section 4.8). Clinical manifestations of NMS include hyperpyrexia, muscle rigidity, altered mental status, and signs of autonomic instability (irregular pulse or unstable blood pressure, tachycardia, sweating, and cardiac arrhythmia). Additional features may include elevated creatine phosphokinase, myoglobinuria (rhabdomyolysis), and acute renal failure. If a patient develops signs and symptoms suggestive of ALS, or presents with unexplained fever without additional clinical manifestations of ALS, brexpiprazole should be discontinued immediately.

Extrapyramidal symptoms

Extrapyramidal symptoms (including acute dystonia) are known class effects.
antipsychotics. Brexpiprazole should be used with caution in patients with a history of extrapyramidal symptoms.

Tardive dyskinesia

Patients receiving antipsychotics may develop a syndrome of persistently irreversible involuntary dyskinetic movements. Although the syndrome is most common in elderly patients, especially elderly women, prevalence estimates cannot be relied upon to predict which patients may develop this syndrome upon initiation of antipsychotic treatment. If signs and symptoms of tardive dyskinesia develop in a patient receiving brexpiprazole, dose reduction or discontinuation of brexpiprazole should be considered. Temporary exacerbation or even recurrence of these symptoms may occur after discontinuation of treatment.

Cerebrovascular adverse reactions

In placebo-controlled trials of some antipsychotics in elderly patients with dementia, a higher incidence of cerebrovascular adverse reactions (stroke and transient ischemic attacks), including fatal events, was observed compared with patients receiving placebo.

Elderly patients with dementia-related psychosis

Brexpiprazole has not been studied in elderly patients with dementia and is not recommended for use in elderly patients with dementia due to an increased risk of all-cause mortality.

Hyperglycemia, in some cases extremely severe and associated with ketoacidosis, hyperosmolar coma, or fatal outcome, has been reported in patients treated with atypical antipsychotics. Risk factors that may predispose a patient to severe complications include obesity and a family history of diabetes mellitus.

Patients treated with antipsychotics, including brexpiprazole, should be observed for signs and symptoms of hyperglycemia (such as polydipsia, polyuria, polyphagia, and weakness). Fasting plasma glucose should be measured prior to or shortly after initiation of antipsychotic therapy. During long-term treatment, plasma glucose should be measured regularly to detect worsening of glucose control.

Weight gain and dyslipidemia

Antipsychotics, including brexpiprazole, have been associated with metabolic changes, including weight gain and dyslipidaemia. An increased incidence of weight gain has been observed with increasing duration of treatment with brexpiprazole (see section 4.8). Lipid profile should be assessed at initiation of treatment. Clinical monitoring of weight and lipid profile is recommended at baseline and during treatment.

Convulsions

As with other antipsychotics, brexpiprazole should be used with caution in patients with a history of seizure disorders or other conditions that could potentially lower the seizure threshold. Seizures have been reported with brexpiprazole (see section 4.8).

Body temperature regulation

The use of antipsychotic drugs is associated with impaired ability to reduce body temperature. Brexpiprazole should be administered with caution to patients with conditions that contribute to an increase in body temperature, including intense physical exertion, exposure to extreme heat, concomitant use of drugs with anticholinergic activity, or dehydration.

Dysphagia

Esophageal motility disorders and aspiration have been associated with the use of antipsychotics. Brexpiprazole should be used with caution in patients at risk of aspiration pneumonia.

Impulse control disorder

Impulse control disorders, including pathological gambling, have been reported in patients treated with brexpiprazole. Patients may experience an increase in pathological gambling, particularly gambling, which they are unable to control.
brexpiprazole. Other reported cases of pathological tendencies include compulsive sexual behavior, compulsive shopping, uncontrolled eating, and other types of impulsive and compulsive behavior. Patients with a history of impulsive disorders may be at increased risk and should be monitored closely. Because patients may not recognize such behaviors as pathological, it is important for physicians to specifically ask patients or their caregivers about the development of new or worsening impulse control disorders or other forms of compulsive behavior during treatment with brexpiprazole. It should be noted that symptoms of impulse control disorder may be related to the underlying disease, but in some cases there have been reports of the pathological tendency disappearing when the dose of the drug is reduced or when treatment is discontinued. Compulsive behavior can harm the patient and others if it is not recognized. If a patient develops such tendencies while taking brexpiprazole
