2.5Dosage Modifications for CYP2D6 Poor Metabolizers and for Concomitant Use with CYP Inhibitors or Inducers
Dosage adjustments are recommended in patients who are known cytochrome P450 (CYP) 2D6 poor metabolizers and in patients taking concomitant CYP3A4 inhibitors or CYP2D6 inhibitors or strong CYP3A4 inducers (see Table 1). If the coadministered drug is discontinued, adjust the brexpiprazole tablets dosage to its original level. If the coadministered CYP3A4 inducer is discontinued, reduce the brexpiprazole tablets dosage to the original level over 1 to 2 weeks [see Drug Interactions (7.1),Clinical Pharmacology (12.3)].
Table 1: Dosage Adjustments of Brexpiprazole Tablets for CYP2D6 Poor Metabolizers and for Concomitant Use with CYP3A4 and CYP2D6 Inhibitors and/or CYP3A4 Inducers *In the clinical trials examining the adjunctive use of brexpiprazole tablets in the treatment of MDD, dosage was not adjusted for strong CYP2D6 inhibitors (e.g., paroxetine, fluoxetine). Thus, CYP considerations are already factored into general dosing recommendations, and brexpiprazole tablets may be administered without dosage adjustment in patients with MDD. Factors Adjusted Brexpiprazole Tablets Dosage CYP2D6 Poor Metabolizers CYP2D6 poor metabolizers Administer half of the usual dose. Known CYP2D6 poor metabolizers taking strong/moderate CYP3A4 inhibitors Administer a quarter of the usual dose. Patients Taking CYP2D6 Inhibitors and/or CYP3A4 Inhibitors Strong CYP2D6 inhibitors* Administer half of the usual dose. Strong CYP3A4 inhibitors Administer half of the usual dose. Strong/moderate CYP2D6 inhibitors with strong/moderate CYP3A4 inhibitors Administer a quarter of the usual dose. Patients Taking CYP3A4 Inducers Strong CYP3A4 inducers Double usual dose over 1 to 2 weeks.

5 Warnings And Precautions
- Cerebrovascular Adverse Reactions in Elderly Patients with Dementia-Related Psychosis: Increased incidence of cerebrovascular adverse reactions (e.g., stroke, transient ischemic attack). (
5.3 )- Neuroleptic Malignant Syndrome: Manage with immediate discontinuation and close monitoring. (
5.4 )- Tardive Dyskinesia: Discontinue if clinically appropriate. (
5.5 )- Metabolic Changes: Monitor for hyperglycemia/diabetes mellitus, dyslipidemia and weight gain. (
5.6 )- Pathological Gambling and Other Compulsive Behaviors: Consider dose reduction or discontinuation. (
5.7 )- Leukopenia, Neutropenia, and Agranulocytosis: Perform complete blood counts (CBC) in patients with pre-existing low white blood cell count (WBC) or history of leukopenia or neutropenia. Consider discontinuing brexpiprazole tablets if a clinically significant decline in WBC occurs in absence of other causative factors. (
5.8 )- Orthostatic Hypotension and Syncope: Monitor heart rate and blood pressure and warn patients with known cardiovascular or cerebrovascular disease, and risk of dehydration or syncope. (
5.9 )- Seizures: Use cautiously in patients with a history of seizures or with conditions that lower the seizure threshold. (
5.11 )5.1Increased Mortality in Elderly Patients with Dementia-Related Psychosis
Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Analyses of 17 placebo-controlled trials (modal duration of 10 weeks), largely in patients taking atypical antipsychotic drugs, revealed a risk of death in drug-treated patients of between 1.6 to 1.7 times the risk of death in placebo-treated patients. Over the course of a typical 10-week controlled trial, the rate of death in drug-treated patients was about 4.5%, compared to a rate of about 2.6% in the placebo group.
Although the causes of death were varied, most of the deaths appeared to be either cardiovascular (e.g., heart failure, sudden death) or infectious (e.g., pneumonia) in nature. Brexpiprazole tablets are not approved for the treatment of patients with dementia-related psychosis [see Boxed Warning, Warnings and Precautions (5.3)].
5.2Suicidal Thoughts and Behaviors in Children, Adolescents and Young Adults
In pooled analyses of placebo-controlled trials of antidepressant drugs (SSRIs and other antidepressant classes) that included approximately 77,000 adult patients and over 4400 pediatric patients, the incidence of suicidal thoughts and behaviors in patients age 24 years and younger was greater in antidepressant-treated patients than in placebo-treated patients. The drug-placebo differences in the number of cases of suicidal thoughts and behaviors per 1000 patients treated are provided in Table 2.
No suicides occurred in any of the pediatric studies. There were suicides in the adult studies, but the number was not sufficient to reach any conclusion about antidepressant drug effect on suicide.
Table 2: Risk Differences of the Number of Patients with Suicidal Thoughts or Behaviors in the Pooled Placebo-Controlled Trials of Antidepressants in Pediatric* and Adult Patients *Brexpiprazole tablets are not approved in pediatric patients with MDD. Age Range (years) Drug-Placebo Difference in Number of Patients with Suicidal Thoughts or Behaviors per 1000 Patients Treated Increases Compared to Placebo <18 14 additional patients 18 to 24 5 additional patients Decreases Compared to Placebo 25 to 64 1 fewer patient ≥65 6 fewer patients
It is unknown whether the risk of suicidal thoughts and behaviors in children, adolescents, and young adults extends to longer-term use, i.e., beyond four months. However, there is substantial evidence from placebo-controlled maintenance studies in adults with MDD that antidepressants delay the recurrence of depression.
Monitor all antidepressant-treated patients for clinical worsening and emergence of suicidal thoughts and behaviors, especially during the initial few months of drug therapy and at times of dosage changes. Counsel family members or caregivers of patients to monitor for changes in behavior and to alert the healthcare provider. Consider changing the therapeutic regimen, including possibly discontinuing brexpiprazole tablets, in patients whose depression is persistently worse or who are experiencing emergent suicidal thoughts or behaviors.
5.3Cerebrovascular Adverse Reactions Including Stroke in Elderly Patients with Dementia-Related Psychosis
In placebo-controlled trials in elderly patients with dementia, patients randomized to risperidone, aripiprazole, and olanzapine had a higher incidence of stroke and transient ischemic attack, including fatal stroke. Brexpiprazole tablets are not approved for the treatment of patients with dementia-related psychosis [see Boxed Warning, Warnings and Precautions (5.1)].
5.4Neuroleptic Malignant Syndrome (NMS)
A potentially fatal symptom complex, sometimes referred to as neuroleptic malignant syndrome (NMS), has been reported in association with administration of antipsychotic drugs, including brexpiprazole tablets. Clinical manifestations of NMS are hyperpyrexia, muscle rigidity, altered mental status, and evidence of autonomic instability. Additional signs may include elevated creatinine phosphokinase, myoglobinuria (rhabdomyolysis), and acute renal failure.
If NMS is suspected, immediately discontinue brexpiprazole tablets and provide intensive symptomatic treatment and monitoring.
5.5Tardive Dyskinesia
Tardive dyskinesia, a syndrome consisting of potentially irreversible, involuntary, dyskinetic movements, may develop in patients treated with antipsychotic drugs. The risk appears to be highest among the elderly, especially elderly women, but it is not possible to predict which patients are likely to develop the syndrome. Whether antipsychotic drugs differ in their potential to cause tardive dyskinesia is unknown.
The risk of tardive dyskinesia and the likelihood that it will become irreversible increase with the duration of treatment and the cumulative dose. The syndrome can develop after a relatively brief treatment period, even at low doses. It may also occur after discontinuation of treatment.
Tardive dyskinesia may remit, partially or completely, if antipsychotic treatment is discontinued. Antipsychotic treatment itself, however, may suppress (or partially suppress) the signs and symptoms of the syndrome, possibly masking the underlying process. The effect that symptomatic suppression has upon the long-term course of tardive dyskinesia is unknown.
Given these considerations, brexpiprazole tablets should be prescribed in a manner most likely to reduce the risk of tardive dyskinesia. Chronic antipsychotic treatment should generally be reserved for patients: (1) who suffer from a chronic illness that is known to respond to antipsychotic drugs; and (2) for whom alternative, effective, but potentially less harmful treatments are not available or appropriate. In patients who do require chronic treatment, use the lowest dose and the shortest duration of treatment needed to produce a satisfactory clinical response. Periodically reassess the need for continued treatment.
If signs and symptoms of tardive dyskinesia appear in a patient on brexpiprazole tablets, drug discontinuation should be considered. However, some patients may require treatment with brexpiprazole tablets despite the presence of the syndrome.
5.6Metabolic Changes
Atypical antipsychotic drugs, including brexpiprazole tablets, have caused metabolic changes, including hyperglycemia, diabetes mellitus, dyslipidemia, and body weight gain. Although all of the drugs in the class to date have been shown to produce some metabolic changes, each drug has its own specific risk profile.
Hyperglycemia and Diabetes Mellitus
Hyperglycemia, in some cases extreme and associated with ketoacidosis or hyperosmolar coma or death, has been reported in patients treated with atypical antipsychotics. There have been reports of hyperglycemia in patients treated with brexpiprazole tablets. Assess fasting plasma glucose before or soon after initiation of antipsychotic medication and monitor periodically during long-term treatment.
Major Depressive Disorder
In the 6-week placebo-controlled, fixed-dose clinical trials in adult patients with MDD, the proportions of patients with shifts in fasting glucose from normal (less than 100 mg/dL) to high (greater than or equal to 126 mg/dL) and borderline (greater than or equal to 100 and less than 126 mg/dL) to high were similar in patients treated with brexpiprazole tablets and placebo.
In the long-term, open-label depression studies, 5% of adult patients with normal baseline fasting glucose experienced a shift to high while taking brexpiprazole tablets plus an antidepressant (ADT); 25% of patients with borderline fasting glucose experienced shifts to high. Combined, 9% of patients with normal or borderline fasting glucose experienced shifts to high fasting glucose during the long-term depression studies.
Schizophrenia
Adults
In the 6-week placebo-controlled, fixed-dose clinical trials in adult patients with schizophrenia, the proportions of patients with shifts in fasting glucose from normal (less than 100 mg/dL) to high (greater than or equal to 126 mg/dL) or borderline (greater than or equal to 100 and less than 126 mg/dL) to high were similar in patients treated with brexpiprazole tablets and placebo.
In the long-term, open-label schizophrenia studies, 8% of adult patients with normal baseline fasting glucose experienced a shift from normal to high while taking brexpiprazole tablets; 17% of patients with borderline fasting glucose experienced shifts from borderline to high. Combined, 10% of patients with normal or borderline fasting glucose experienced shifts to high fasting glucose during the long-term schizophrenia studies.
Dyslipidemia
Atypical antipsychotics cause adverse alterations in lipids. Before or soon after initiation of antipsychotic medication, obtain a fasting lipid profile at baseline and monitor periodically during treatment.
Major Depressive Disorder
In the 6-week placebo-controlled, fixed-dose clinical trials in adult patients with MDD, changes in fasting total cholesterol, LDL cholesterol, and HDL cholesterol were similar in brexpiprazole tablets- and placebo-treated patients. Table 3 shows the proportions of patients with changes in fasting triglycerides.

In the long-term, open-label depression studies, shifts in baseline fasting cholesterol from normal to high were reported in 9% (total cholesterol), 3% (LDL cholesterol), and shifts in baseline from normal to low were reported in 14% (HDL cholesterol) of patients taking brexpiprazole tablets. Of patients with normal baseline triglycerides, 17% experienced shifts to high, and 0.2% experienced shifts to very high. Combined, 0.6% of patients with normal or borderline fasting triglycerides experienced shifts to very high fasting triglycerides during the long-term depression studies.
Schizophrenia
Adults
In the 6-week placebo-controlled, fixed-dose clinical trials in adult patients with schizophrenia, changes in fasting total cholesterol, LDL cholesterol, and HDL cholesterol were similar in brexpiprazole tablets- and placebo-treated patients. Table 4 shows the proportions of patients with changes in fasting triglycerides.

In the long-term, open-label schizophrenia studies in adult patients, shifts in baseline fasting cholesterol from normal to high were reported in 6% (total cholesterol), 2% (LDL cholesterol), and shifts in baseline from normal to low were reported in 17% (HDL cholesterol) of patients taking brexpiprazole tablets. Of patients with normal baseline triglycerides, 13% experienced shifts to high, and 0.4% experienced shifts to very high triglycerides. Combined, 0.6% of patients with normal or borderline fasting triglycerides experienced shifts to very high fasting triglycerides during the long-term schizophrenia studies.
Weight Gain
Weight gain has been observed in patients treated with atypical antipsychotics, including brexpiprazole tablets. Monitor weight at baseline and frequently thereafter.
Major Depressive Disorder
Table 5 shows weight gain data at last visit and percentage of adult patients with greater than or equal to 7% increase in body weight at endpoint from the 6-week placebo-controlled, fixed-dose clinical studies in patients with MDD.

5.7Pathological Gambling and Other Compulsive Behaviors
Post-marketing case reports suggest that patients can experience intense urges, particularly for gambling, and the inability to control these urges while taking brexpiprazole tablets. Other compulsive urges, reported less frequently, include sexual urges, shopping, eating, or binge eating, and other impulsive or compulsive behaviors. Because patients may not recognize these behaviors as abnormal, it is important for prescribers to ask patients or their caregivers specifically about the development of new or intense gambling urges, compulsive sexual urges, compulsive shopping, binge or compulsive eating, or other urges while being treated with brexpiprazole tablets. In some cases, although not all, urges were reported to have stopped when the dose was reduced, or the medication was discontinued. Compulsive behaviors may result in harm to the patient and others if not recognized. Consider dose reduction or stopping the medication if a patient develops such urges.
5.8Leukopenia, Neutropenia, and Agranulocytosis
Leukopenia and neutropenia have been reported during treatment with antipsychotic agents. Agranulocytosis (including fatal cases) has been reported with other agents in this class.
Possible risk factors for leukopenia and neutropenia include pre-existing low white blood cell count (WBC) or absolute neutrophil count (ANC) and history of drug-induced leukopenia or neutropenia. In patients with a pre-existing low WBC or ANC or a history of drug-induced leukopenia or neutropenia, perform a complete blood count (CBC) frequently during the first few months of therapy. In such patients, consider discontinuation of brexpiprazole tablets at the first sign of a clinically significant decline in WBC in the absence of other causative factors.
Monitor patients with clinically significant neutropenia for fever or other symptoms or signs of infection and treat promptly if such symptoms or signs occur. Discontinue brexpiprazole tablets in patients with absolute neutrophil count less than 1000/mm3 and follow their WBC until recovery.
5.9Orthostatic Hypotension and Syncope
Atypical antipsychotics cause orthostatic hypotension and syncope. Generally, the risk is greatest during initial dose titration and when increasing the dose. In the short-term, placebo-controlled clinical studies of brexpiprazole tablets plus ADT in adult patients with MDD, the incidence of orthostatic hypotension-related adverse reactions in brexpiprazole tablets plus ADT-treated patients compared to placebo plus ADT-treated patients included: dizziness (2% versus 2%) and orthostatic hypotension (0.1% versus 0%). In the short-term, placebo-controlled clinical studies of brexpiprazole tablets in adult patients with schizophrenia, the incidence of orthostatic hypotension-related adverse reactions in brexpiprazole tablets-treated patients compared to placebo patients included: dizziness (2% versus 2%), orthostatic hypotension (0.4% versus 0.2%), and syncope (0.1% versus 0%).
Orthostatic vital signs should be monitored in patients who are vulnerable to hypotension (e.g., elderly patients, patients with dehydration, hypovolemia, concomitant treatment with antihypertensive medication), patients with known cardiovascular disease (history of myocardial infarction, ischemic heart disease, heart failure, or conduction abnormalities), and patients with cerebrovascular disease. Brexpiprazole tablets has not been evaluated in patients with a recent history of myocardial infarction or unstable cardiovascular disease. Such patients were excluded from the premarketing clinical trials.
5.10Falls
Antipsychotics, including brexpiprazole tablets, may cause somnolence, postural hypotension, motor, and sensory instability, which may lead to falls and, consequently, fractures or other injuries. For patients with diseases, conditions, or medications that could exacerbate these effects, complete fall risk assessments when initiating antipsychotic treatment and recurrently for patients on long-term antipsychotic therapy.
5.11Seizures
Like other antipsychotic drugs, brexpiprazole tablets may cause seizures. This risk is greatest in patients with a history of seizures or with conditions that lower the seizure threshold. Conditions that lower the seizure threshold may be more prevalent in older patients.
5.12Body Temperature Dysregulation
Atypical antipsychotics may disrupt the body’s ability to reduce core body temperature. Strenuous exercise, exposure to extreme heat, dehydration, and anticholinergic medications may contribute to an elevation in core body temperature; use brexpiprazole tablets with caution in patients who may experience these conditions.
5.13Dysphagia
Esophageal dysmotility and aspiration have been associated with antipsychotic drug use. Antipsychotic drugs, including brexpiprazole tablets, should be used cautiously in patients at risk for aspiration.
5.14Potential for Cognitive and Motor Impairment
Brexpiprazole tablets, like other antipsychotics, has the potential to impair judgment, thinking, or motor skills. In the 6-week placebo-controlled clinical trials in patients with MDD, somnolence (including sedation and hypersomnia) was reported in 4% of brexpiprazole tablets plus ADT-treated patients compared to 1% of placebo plus ADT-treated patients.
In the 6-week placebo-controlled clinical trials in adult patients with schizophrenia, somnolence (including sedation and hypersomnia) was reported in 5% of brexpiprazole tablets-treated patients compared to 3% of placebo-treated patients.
Patients should be cautioned about operating hazardous machinery, including motor vehicles, until they are reasonably certain that brexpiprazole tablets therapy does not affect them adversely.

6.1Clinical Trial Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
Major Depressive Disorder
The safety of brexpiprazole tablets was evaluated in 1054 adult patients (18 to 65 years of age) diagnosed with MDD who participated in two 6-week placebo-controlled, fixed-dose clinical trials in patients with major depressive disorder in which brexpiprazole tablets was administered at doses of 1 mg to 3 mg daily as adjunctive treatment to continued antidepressant therapy; patients in the placebo group continued to receive antidepressant therapy [see Clinical Studies ( 14.1)].
Adverse Reactions Reported as Reasons for Discontinuation of Treatment
A total of 3% (17/643) of brexpiprazole tablets-treated patients and 1% (3/411) of placebo-treated patients discontinued due to adverse reactions.

Dose-Related Adverse Reactions in the MDD Trials
In Studies 1 and 2, among the adverse reactions that occurred at greater than or equal to 2% incidence in the patients treated with brexpiprazole tablets plus ADT, the incidences of akathisia and restlessness increased with increases in dose.
Schizophrenia
Adults
The safety of brexpiprazole tablets was evaluated in 852 adult patients (18 to 65 years of age) diagnosed with schizophrenia who participated in two 6-week placebo-controlled, fixed-dose clinical trials in which brexpiprazole tablets was administered at daily doses of 1 mg, 2 mg and 4 mg [see Clinical Studies ( 14.2)].

Extrapyramidal Symptoms
Major Depressive Disorder
The incidence of reported extrapyramidal symptoms (EPS)-related adverse reactions, excluding akathisia, was 6% for brexpiprazole tablets plus ADT-treated patients versus 3% for placebo plus ADT-treated patients. The incidence of akathisia events for brexpiprazole tablets plus ADT-treated patients was 9% versus 2% for placebo plus ADT-treated patients.
In the 6-week placebo-controlled MDD studies, data was objectively collected on the Simpson-Angus Rating Scale (SAS) for EPS, the Barnes Akathisia Rating Scale (BARS) for akathisia and the Abnormal Involuntary Movement Score (AIMS) for dyskinesia. The mean change from baseline at last visit for brexpiprazole tablets plus ADT-treated patients for the SAS, BARS and AIMS was comparable to placebo-treated patients. The percentage of patients who shifted from normal to abnormal was greater in brexpiprazole tablets plus ADT-treated patients versus placebo plus ADT-treated patients for the BARS (4% versus 0.6%) and the SAS (4% versus 3%).
Schizophrenia
The incidence of reported EPS-related adverse reactions, excluding akathisia, was 5% for brexpiprazole tablets-treated patients versus 4% for placebo-treated patients. The incidence of akathisia events for brexpiprazole tablets-treated patients was 6% versus 5% for placebo-treated patients.
In the 6-week placebo-controlled, fixed-dose schizophrenia studies in adults, data was objectively collected on the Simpson-Angus Rating Scale (SAS) for EPS, the Barnes Akathisia Rating Scale (BARS) for akathisia and the Abnormal Involuntary Movement Scale (AIMS) for dyskinesia. The mean change from baseline at last visit for brexpiprazole tablets-treated patients for the SAS, BARS and AIMS was comparable to placebo-treated patients. The percentage of patients who shifted from normal to abnormal was greater in brexpiprazole tablets-treated patients versus placebo for the BARS (2% versus 1%) and the SAS (7% versus 5%).
Dystonia
Symptoms of dystonia may occur in susceptible individuals during the first few days of treatment. Dystonic symptoms include spasm of the neck muscles, sometimes progressing to tightness of the throat, swallowing difficulty, difficulty breathing, and/or protrusion of the tongue. While these symptoms can occur at low doses, they occur more frequently and with greater severity with high potency and at higher doses of first-generation antipsychotic drugs. An elevated risk of acute dystonia is observed in males and younger age groups.

7 Drug Interactions
*Brexpiprazole tablets may be administered without dosage adjustment in patients with MDD when administered with strong CYP2D6 inhibitors (e.g., paroxetine, fluoxetine). Factors Dosage Adjustments for brexpiprazole tablets ( 2.5 )Strong CYP2D6* or CYP3A4 inhibitors Administer half of usual dose. Strong/moderate CYP2D6 with Strong/moderate CYP3A4 inhibitors Administer a quarter of usual dose. Known CYP2D6 poor metabolizers taking strong/moderate CYP3A4 inhibitors Administer a quarter of usual dose. Strong CYP3A4 inducers Double the usual dose and further adjust based on clinical response. 7.1 Drugs Having Clinically Important Interactions with Brexpiprazole Tablets
Table 9: Clinically Important Drug Interactions with Brexpiprazole Tablets * In the clinical trials examining the adjunctive use of brexpiprazole tablets in the treatment of MDD, dosage was not adjusted for strong CYP2D6 inhibitors (e.g., paroxetine, fluoxetine). Thus, CYP considerations are already factored into general dosing recommendations, and brexpiprazole tablets may be administered without dosage adjustment in patients with MDD. Strong CYP3A4 Inhibitors Clinical Impact: Concomitant use of brexpiprazole tablets with strong CYP3A4 inhibitors increased the exposure of brexpiprazole compared to the use of brexpiprazole tablets alone [see Clinical Pharmacology (12.3)]. Intervention: With concomitant use of brexpiprazole tablets with a strong CYP3A4 inhibitor, reduce the brexpiprazole tablets dosage [see Dosage and Administration (2.5)]. Strong CYP2D6 Inhibitors* Clinical Impact: Concomitant use of brexpiprazole tablets with strong CYP2D6 inhibitors increased the exposure of brexpiprazole compared to the use of brexpiprazole tablets alone [see Clinical Pharmacology (12.3)]. Intervention: With concomitant use of brexpiprazole tablets with a strong CYP2D6 inhibitor, reduce the brexpiprazole tablets dosage [see Dosage and Administration (2.5)]. Both CYP3A4 Inhibitors and CYP2D6 Inhibitors Clinical Impact: Concomitant use of brexpiprazole tablets with 1) a strong CYP3A4 inhibitor and a strong CYP2D6 inhibitor; or 2) a moderate CYP3A4 inhibitor and a strong CYP2D6 inhibitor; or 3) a strong CYP3A4 inhibitor and a moderate CYP2D6 inhibitor; or 4) a moderate CYP3A4 inhibitor and a moderate CYP2D6 inhibitor, increased the exposure of brexpiprazole compared to the use of brexpiprazole tablets alone [see Clinical Pharmacology (12.3)] . Intervention: With concomitant use of brexpiprazole tablets with 1) a strong CYP3A4 inhibitor and a strong CYP2D6 inhibitor; or 2) a moderate CYP3A4 inhibitor and a strong CYP2D6 inhibitor; or 3) a strong CYP3A4 inhibitor and a moderate CYP2D6 inhibitor; or 4) a moderate CYP3A4 inhibitor and a moderate CYP2D6 inhibitor, decrease the brexpiprazole tablets dosage [see Dosage and Administration (2.5)] . Strong CYP3A4 Inducers Clinical Impact: Concomitant use of brexpiprazole tablets and a strong CYP3A4 inducer decreased the exposure of brexpiprazole compared to the use of brexpiprazole tablets alone [see Clinical Pharmacology (12.3)]. Intervention: With concomitant use of brexpiprazole tablets with a strong CYP3A4 inducer, increase the brexpiprazole tablets dosage [see Dosage and Administration (2.5)]. 7.2Drugs Having No Clinically Important Interactions with Brexpiprazole Tablets
Based on pharmacokinetic studies, no dosage adjustment of brexpiprazole tablets is required when administered concomitantly with CYP2B6 inhibitors (e.g., ticlopidine) or gastric pH modifiers (e.g., omeprazole). Additionally, no dosage adjustment for substrates of CYP2D6 (e.g., dextromethorphan), CYP3A4 (e.g., lovastatin), CYP2B6 (e.g., bupropion), BCRP (e.g., rosuvastatin), or P-gp (e.g., fexofenadine) is required when administered concomitantly with brexpiprazole tablets.
8 Use In Specific Populations
Pregnancy: May cause extrapyramidal and/or withdrawal symptoms in neonates with third trimester exposure (8.1 )
Pediatric use information is approved for Otsuka Pharmaceutical Company, Ltd.’s Rexulti® (brexpiprazole) tablets. However, due to Otsuka Pharmaceutical Company, Ltd.’s marketing exclusivity rights, this drug product is not labeled with that information.
8.1 Pregnancy
Pregnancy Exposure Registry
There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to brexpiprazole tablets during pregnancy. For more information contact the National Pregnancy Registry for Atypical Antipsychotics at 1-866-961-2388 or visit http://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/.
Risk Summary
Adequate and well-controlled studies have not been conducted with brexpiprazole tablets in pregnant women to inform drug-associated risks. However, neonates whose mothers are exposed to antipsychotic drugs, like brexpiprazole tablets, during the third trimester of pregnancy are at risk for extrapyramidal and/or withdrawal symptoms. In animal reproduction studies, no teratogenicity was observed with oral administration of brexpiprazole to pregnant rats and rabbits during organogenesis at doses up to 73 and 146 times, respectively, of maximum recommended human dose (MRHD) of 4 mg/day on a mg/m2 basis. However, when pregnant rats were administered brexpiprazole during the period of organogenesis through lactation, the number of perinatal deaths of pups was increased at 73 times the MRHD [see Data]. The background risk of major birth defects and miscarriage for the indicated population(s) is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.
Clinical Considerations
Fetal/Neonatal Adverse Reactions
Extrapyramidal and/or withdrawal symptoms, including agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress and feeding disorder, have been reported in neonates whose mothers were exposed to antipsychotic drugs during the third trimester of pregnancy. These symptoms have varied in severity. Some neonates recovered within hours or days without specific treatment; others required prolonged hospitalization. Monitor neonates for extrapyramidal and/or withdrawal symptoms and manage symptoms appropriately.
Data
Animal Data
Pregnant rats were treated with oral doses of 3 mg/kg/day, 10 mg/kg/day, and 30 mg/kg/day (7.3, 24, and 73 times the MRHD on a mg/m2 basis) of brexpiprazole during the period of organogenesis. Brexpiprazole was not teratogenic and did not cause adverse developmental effects at doses up to 73 times the MRHD.
Pregnant rabbits were treated with oral doses of 10 mg/kg/day, 30 mg/kg/day, and 150 mg/kg/day (49, 146, and 730 times the MRHD) of brexpiprazole during the period of organogenesis. Brexpiprazole was not teratogenic and did not cause adverse developmental effects at doses up to 146 times the MRHD. Findings of decreased body weight, retarded ossification, and increased incidences of visceral and skeletal variations were observed in fetuses at 730 times the MRHD, a dose that induced maternal toxicity.
In a study in which pregnant rats were administered oral doses of 3 mg/kg/day, 10 mg/kg/day, and 30 mg/kg/day (7.3, 24, and 73 times the MRHD) during the period of organogenesis and through lactation, the number of live-born pups was decreased, and early postnatal deaths increased at a dose 73 times the MRHD. Impaired nursing by dams, and low birth weight and decreased body weight gain in pups were observed at 73 times, but not at 24 times, the MRHD.
8.2 Lactation
Risk Summary
Lactation studies have not been conducted to assess the presence of brexpiprazole in human milk, the effects of brexpiprazole on the breastfed infant, or the effects of brexpiprazole on milk production. Brexpiprazole is present in rat milk. The development and health benefits of breastfeeding should be considered along with the mother’s clinical need for brexpiprazole tablets and any potential adverse effects on the breastfed infant from brexpiprazole tablets or from the underlying maternal condition.
8.4 Pediatric Use
Major Depressive Disorder Safety and effectiveness in pediatric patients with major depressive disorder have not been established. Antidepressants increased the risk of suicidal thoughts and behaviors in pediatric patients [see Boxed Warning, Warnings and Precautions (5.2)].
Pediatric use information is approved for Otsuka Pharmaceutical Company, Ltd.’s Rexulti® (brexpiprazole) tablets. However, due to Otsuka Pharmaceutical Company, LTD.’s marketing exclusivity rights, this drug product is not labeled with that information.
8.5 Geriatric Use
Clinical studies of the efficacy of brexpiprazole tablets did not include any patients aged 65 or older to determine whether they respond differently from younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, and cardiac function, concomitant diseases, and other drug therapy.
Based on the results of a safety, tolerability, and pharmacokinetics trial, the pharmacokinetics of once daily oral administration of brexpiprazole (up to 3 mg/day for 14 days) as an adjunct therapy in the treatment of elderly patients (70 to 85 years old, N=11) with MDD were comparable to those observed in adult patients with MDD.
Antipsychotic drugs increase the risk of death in elderly patients with dementia-related psychosis. Brexpiprazole tablets are not approved for the treatment of patients with dementia-related psychosis [see Boxed Warning, Warnings and Precautions (5.1)].
8.6CYP2D6 Poor Metabolizers
Dosage adjustment is recommended in known CYP2D6 poor metabolizers, because these patients have higher brexpiprazole concentrations than normal metabolizers of CYP2D6. Approximately 8% of Caucasians and 3% to 8% of Black/African Americans cannot metabolize CYP2D6 substrates and are classified as poor metabolizers [see Dosage and Administration (2.5), Clinical Pharmacology (12.3)].
8.7Hepatic Impairment
Reduce the maximum recommended dosage in patients with moderate to severe hepatic impairment (Child-Pugh score greater than or equal to 7). Patients with moderate to severe hepatic impairment (Child-Pugh score greater than or equal to 7) generally had higher exposure to brexpiprazole than patients with normal hepatic function [see Clinical Pharmacology (12.3)]. Greater exposure may increase the risk of brexpiprazole tablets-associated adverse reactions [see Dosage and Administration (2.3)].
8.8Renal Impairment
Reduce the maximum recommended dosage in patients with moderate, severe, or end-stage renal impairment (CrCl less than 60 mL/minute). Patients with impaired renal function (CrCl less than 60 mL/minute) had higher exposure to brexpiprazole than patients with normal renal function [see Clinical Pharmacology (12.3)]. Greater exposure may increase the risk of brexpiprazole tablets-associated adverse reactions [see Dosage and Administration (2.4)].
8.9Other Specific Populations
No dosage adjustment for brexpiprazole tablets is required on the basis of a patient’s sex, race, or smoking status [see Clinical Pharmacology (12.3)].
9 Drug Abuse And Dependence
9.1 Controlled Substance
Brexpiprazole is not a controlled substance.
9.2 Abuse
Animals given access to brexpiprazole tablets did not self-administer the drug, suggesting that brexpiprazole tablets does not have rewarding properties.
9.3 Dependence
Humans and animals that received chronic brexpiprazole tablets administration did not demonstrate any withdrawal signs upon drug discontinuation. This suggests that brexpiprazole tablets does not produce physical dependence.
10 Overdosage
There is limited clinical trial experience regarding human overdosage with brexpiprazole tablets.
Consult a Certified Poison Control Center (1-800-222-1222 or www.poison.org) for up-to-date guidance and advice regarding a brexpiprazole tablets overdosage. Management of overdose should concentrate on supportive therapy, maintaining an adequate airway, oxygenation and ventilation, and management of symptoms. Close medical supervision and monitoring should continue until the patient recovers.
Charcoal Oral activated charcoal and sorbitol (50 g/240 mL), administered one hour after ingesting oral brexpiprazole, decreased brexpiprazole Cmax and area under the curve (AUC) by approximately 5% to 23% and 31% to 39% respectively; however, there is insufficient information available on the therapeutic potential of activated charcoal in treating an overdose with brexpiprazole tablets.
Hemodialysis There is no information on the effect of hemodialysis in treating an overdose with brexpiprazole tablets; hemodialysis is unlikely to be useful because brexpiprazole is highly bound to plasma proteins.
11 Description

Inactive ingredients include microcrystalline cellulose, lactose monohydrate, low-substituted hydroxypropyl cellulose, hydroxypropyl cellulose, magnesium stearate, hypromellose, talc, propylene glycol, polyethylene glycol. Colorants includes titanium dioxide, iron oxide red (0.25 mg and 3 mg), FD&C Yellow #6 (0.5 mg), iron oxide yellow (1 mg, 2 mg and 3 mg), FD&C Blue #2 (2 mg).
12 Clinical Pharmacology
12.1 Mechanism of Action
The mechanism of action of brexpiprazole in the treatment of major depressive disorder or schizophrenia is unknown. However, the efficacy of brexpiprazole may be mediated through a combination of partial agonist activity at serotonin 5-HT1A and dopamine D2 receptors, and antagonist activity at serotonin 5-HT2A receptors.
12.2 Pharmacodynamics
Brexpiprazole has affinity (expressed as Ki) for multiple monoaminergic receptors including serotonin 5-HT1A (0.12 nM), 5-HT2A (0.47 nM), 5-HT2B (1.9 nM), 5-HT7 (3.7 nM), dopamine D2 (0.30 nM), D3 (1.1 nM), and noradrenergic α1A (3.8 nM), α1B (0.17 nM), α1D (2.6 nM), and α2C (0.59 nM) receptors. Brexpiprazole acts as a partial agonist at the 5-HT1A, D2, and D3 receptors and as an antagonist at 5-HT2A, 5-HT2B, 5-HT7, α1A, α1B, α1D, and α2C receptors. Brexpiprazole also exhibits affinity for histamine H1 receptor (19 nM) and for muscarinic M1 receptor (67% inhibition at 10 µM).
Cardiac Electrophysiology
At a dose 3 times the MRHD for the treatment of schizophrenia and 4 times the MRHD for adjunctive therapy to antidepressants for the treatment of MDD, brexpiprazole tablets does not prolong the QTc interval to any clinically relevant extent.
12.3 Pharmacokinetics
Absorption After single-dose administration of brexpiprazole tablets, the peak plasma brexpiprazole concentrations occurred within 4 hours after administration, and the absolute oral bioavailability was 95%. Brexpiprazole steady-state concentrations were attained within 10 to 12 days of dosing.
Brexpiprazole tablets can be administered with or without food. Administration of a 4 mg brexpiprazole tablet with a standard high-fat meal did not significantly affect the Cmax or AUC of brexpiprazole. After single and multiple once daily dose administration, brexpiprazole exposure (Cmax and AUC) increased in proportion to the dose administered. In vitro studies of brexpiprazole did not indicate that brexpiprazole is a substrate of efflux transporters such as MDRI (P-gp) and BCRP.
Distribution The volume of distribution of brexpiprazole following intravenous administration is high (1.56±0.42 L/kg), indicating extravascular distribution. Brexpiprazole is highly protein bound in plasma (greater than 99%) to serum albumin and α1-acid glycoprotein, and its protein binding is not affected by renal or hepatic impairment. Based on results of in vitro studies, brexpiprazole protein binding is not affected by warfarin, diazepam, or digitoxin.
Elimination Metabolism Based on in vitro metabolism studies of brexpiprazole using recombinant human cytochrome P450 (CYP1A1, 1A2, 2A6, 2B6, 2C8, 2C9, 2C19, 2D6, 2E1, and 3A4), the metabolism of brexpiprazole was shown to be mainly mediated by CYP3A4 and CYP2D6.
In vivo brexpiprazole is metabolized primarily by CYP3A4 and CYP2D6 enzymes. After single- and multiple-dose administrations, brexpiprazole and its major metabolite, DM-3411, were the predominant drug moieties in the systemic circulation. At steady-state, DM-3411 represented 23% to 48% of brexpiprazole exposure (AUC) in plasma. DM-3411 is considered not to contribute to the therapeutic effects of brexpiprazole.
Based on in vitro data, brexpiprazole showed little to no inhibition of CYP450 isozymes.
Excretion Following a single oral dose of [14C]-labeled brexpiprazole, approximately 25% and 46% of the administered radioactivity was recovered in the urine and feces, respectively. Less than 1% of unchanged brexpiprazole was excreted in the urine, and approximately 14% of the oral dose was recovered unchanged in the feces. Apparent oral clearance of a brexpiprazole oral tablet after once daily administration is 19.8 (±11.4) mL/h/kg. After multiple once-daily administrations of brexpiprazole tablets, the terminal elimination half-lives of brexpiprazole and its major metabolite, DM-3411, were 91 hours and 86 hours, respectively.
Studies in Specific Populations Exposure of brexpiprazole in specific populations are summarized in Figure 1. Population pharmacokinetic (PK) analysis indicated exposure of brexpiprazole in patients with moderate renal impairment was higher compared to patients with normal renal function.

Drug Interaction Studies
Effects of other drugs on the exposures of brexpiprazole are summarized in Figure 2. Based on simulation, a 5.1-fold increase in AUC values at steady-state is expected when extensive metabolizers of CYP2D6 are administered with both strong CYP2D6 and CYP3A4 inhibitors. A 4.8-fold increase in mean AUC values at steady-state is expected in poor metabolizers of CYP2D6 administered with strong CYP3A4 inhibitors [see Drug Interactions (7.1)].

13 Nonclinical Toxicology
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
Carcinogenesis
Lifetime carcinogenicity studies were conducted in ICR mice and Sprague Dawley rats. Brexpiprazole was administered orally for two years to male and female mice at doses of 0.75 mg/kg/day, 2 mg/kg/day, and 5 mg/kg/day (0.9 to 6.1 times the oral MRHD of 4 mg/day based on mg/m2 body surface area) and to male and female rats at doses of 1 mg/kg, 3 mg/kg, and 10 mg/kg and 3 mg/kg/day, 10 mg/kg/day, and 30 mg/kg/day, respectively (2.4 to 24 and 7.3 to 73 times the oral MRHD, males and females). In female mice, the incidence of mammary gland adenocarcinoma was increased at all doses, and the incidence of adenosquamous carcinoma was increased at 2.4 and 6.1 times the MRHD. No increase in the incidence of tumors was observed in male mice. In the rat study, brexpiprazole was not carcinogenic in either sex at doses up to 73 times the MRHD.
Proliferative and/or neoplastic changes in the mammary and pituitary glands of rodents have been observed following chronic administration of antipsychotic drugs and are considered to be prolactin mediated. The potential for increasing serum prolactin level of brexpiprazole was shown in both mice and rats. The relevance for human risk of the findings of prolactin-mediated endocrine tumors in rodents is unknown.
Mutagenesis
Brexpiprazole was not mutagenic when tested in the in vitro bacterial reverse mutation assay (Ames test). Brexpiprazole was negative for clastogenic activity in the in vivo micronucleus assay in rats and was not genotoxic in the in vivo/in vitro unscheduled DNA synthesis assay in rats. In vitro with mammalian cells brexpiprazole was clastogenic but only at doses that induced cytotoxicity. Based on a weight of evidence, brexpiprazole is not considered to present a genotoxic risk to humans.
Impairment of Fertility
Female rats were treated with oral doses of 0.3 mg/kg/day, 3 mg/kg/day, or 30 mg/kg/day (0.7, 7.3, and 73 times the oral MRHD on a mg/m2 basis) prior to mating with untreated males and continuing through conception and implantation. Estrus cycle irregularities and decreased fertility were observed at 3 mg/kg/day and 30 mg/kg/day. Prolonged duration of pairing and increased preimplantation losses were observed at 30 mg/kg/day.
Male rats were treated with oral doses of 3 mg/kg/day, 10 mg/kg/day, or 100 mg/kg/day (7.3, 24, and 240 times the oral MRHD on a mg/m2 basis) for 63 days prior to mating with untreated females and throughout the 14 days of mating. No differences were observed in the duration of mating or fertility indices in males at any dose of brexpiprazole.
14 Clinical Studies
14.1Adjunctive Treatment of Major Depressive Disorder
The efficacy of brexpiprazole tablets in the adjunctive treatment of major depressive disorder (MDD) was evaluated in two 6-week double-blind, placebo-controlled, fixed-dose trials of adult patients meeting DSM-IV-TR criteria for MDD, with or without symptoms of anxiety, who had an inadequate response to prior antidepressant therapy (1 to 3 courses) in the current episode and who had also demonstrated an inadequate response throughout the 8 weeks of prospective antidepressant treatment (with escitalopram, fluoxetine, paroxetine controlled-release, sertraline, duloxetine delayed release, or venlafaxine extended release). Inadequate response during the prospective antidepressant treatment phase was defined as having persistent symptoms without substantial improvement throughout the course of treatment.
Patients in Study 228 (hereafter “Study 1”) were randomized to brexpiprazole tablets 2 mg once a day or placebo. Patients in Study 227 (hereafter “Study 2”) were randomized to brexpiprazole tablets 1 mg or 3 mg once a day or placebo. For patients randomized to brexpiprazole tablets, all patients initiated treatment at 0.5 mg once daily during Week 1. At Week 2, the brexpiprazole tablets dosage was increased to 1 mg in all treatment groups, and either maintained at 1 mg or increased to 2 mg or 3 mg once daily, based on treatment assignment, from Week 3 onwards. The dosages were then maintained for the 4 remaining weeks.
The primary endpoint was change from baseline to Week 6 in the Montgomery-Asberg Depression Rating Scale (MADRS), a 10-li clinician-related scale used to assess the degree of depressive symptomatology, with 0 representing no symptoms and 60 representing worst symptoms.
At randomization, the mean MADRS total score was 27. In Studies 1 and 2, brexpiprazole tablets (plus ADT) 2 mg/day and 3 mg/day were superior to placebo plus ADT in reducing mean MADRS total scores.

14.2Schizophrenia
The efficacy of brexpiprazole tablets in the treatment of adults with schizophrenia was demonstrated in two 6-week randomized, double-blind, placebo-controlled, fixed-dose clinical trials in patients who met DSM-IV-TR criteria for schizophrenia.
In both studies, Study 231 (hereafter “Study 3”) and Study 230 (hereafter “Study 4”), patients were randomized to brexpiprazole tablets 2 or 4 mg once per day or placebo. Patients in the brexpiprazole tablets groups initiated treatment at 1 mg once daily on Days 1 to 4. The brexpiprazole tablets dosage was increased to 2 mg on Days 5 to 7. The dosage was then either maintained at 2 mg once daily or increased to 4 mg once daily, depending on treatment assignment, for the 5 remaining weeks.
The primary efficacy endpoint of both trials was the change from baseline to Week 6 in the Positive and Negative Syndrome Scale (PANSS) total score. The PANSS is a 30-li scale that measures positive symptoms of schizophrenia (7 lis), negative symptoms of schizophrenia (7 lis), and general psychopathology (16 lis), each rated on a scale of 1 (absent) to 7 (extreme); the total PANSS scores range from 30 (best) to 210 (worst).
In Study 3, brexpiprazole tablets at both 2 mg/day and 4 mg/day was superior to placebo on the PANSS total score. In Study 4, brexpiprazole tablets 4 mg/day was superior to placebo on the PANSS total score (Table 11). Figure 5 shows the time course of response based on the primary efficacy measure (change from baseline in PANSS total score) in Study 3.

Figure 5: Change from Baseline in PANSS Total Score by Study Visit (Week) in Adult Patients with Schizophrenia (Study 3)
The safety and efficacy of brexpiprazole tablets as maintenance treatment in adults with schizophrenia aged 18 to 65 years were demonstrated in the maintenance phase of a randomized withdrawal trial (Study 331-10-232, hereafter “Study 5”). Patients were stabilized for at least 12 weeks on 1 mg/day to 4 mg/day of brexpiprazole tablets (N=202). They were then randomized in the double-blind treatment phase to either continue brexpiprazole tablets at their achieved stable dose (N=97), or to switch to placebo (N=105).
The primary endpoint in Study 5 was time from randomization to impending relapse during the double-blind phase, defined as: 1) Clinical Global Improvement score of greater than or equal to 5 (minimally worse) and an increase to a score greater than 4 on PANSS conceptual disorganization, hallucinatory behavior, suspiciousness, or unusual thought content lis, with either a greater than or equal to 2 increase on a specific li or greater than or equal to 4 point increase on the combined four PANSS lis, 2) hospitalization due to worsening of psychotic symptoms, 3) current suicidal behavior, or 4) violent/aggressive behavior.
A pre-specified interim analysis demonstrated a statistically significantly longer time to relapse in patients randomized to the brexpiprazole tablets group compared to placebo-treated patients. The trial was subsequently terminated early because maintenance of efficacy had been demonstrated. The Kaplan-Meier curves of the cumulative proportion of patients with relapse during the double-blind treatment phase for brexpiprazole tablets and placebo groups are shown in Figure 6. The key secondary endpoint, the proportion of patients who met the criteria for impending relapse, was statistically significantly lower in brexpiprazole tablets-treated patients compared with placebo group.

Note: A total of 202 patients were randomized. Among them, one placebo patient did not take investigational medicinal product and one brexpiprazole patient did not have post-randomization efficacy evaluations. These two patients were excluded from the efficacy analysis.
