To report SUSPECTED ADVERSE REACTIONS, contact Amneal Pharmaceuticals at 1-877-835-5472 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials 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 was evaluated in 1,054 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 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-treated patients and 1% (3/411) of placebo-treated patients discontinued due to adverse reactions. Common Adverse Reactions Adverse reactions associated with the adjunctive use of brexpiprazole (incidence of 2% or greater and adjunctive brexpiprazole incidence greater than adjunctive placebo) that occurred during acute therapy (up to 6-weeks in patients with MDD) are shown in Table 7.

Schizophrenia Adults The safety of brexpiprazole 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 was administered at daily doses of 1 mg, 2 mg and 4 mg [see Clinical Studies (14.2)]. Common Adverse Reactions Adverse reactions associated with brexpiprazole (incidence of 2% or greater and brexpiprazole incidence greater than placebo) during short-term (up to 6 weeks) trials in adult patients with schizophrenia are shown in Table 8. Table 8: Adverse Reactions in Pooled 6-Week Placebo-Controlled, Fixed-Dose Schizophrenia Trials in Adult Patients (Studies 3 and 4)* Placebo (N=368) Brexpiprazole 1 mg/day (N=120) 2 mg/day (N=368) 4 mg/day (N=364) ALL Brexpiprazole (N=852) Gastrointestinal Disorders Dyspepsia 2% 6% 2% 3% 3% Diarrhea 2% 1% 3% 3% 3% Investigations Weight Increased 2% 3% 4% 4% 4% Blood Creatinine Phosphokinase Increased 1% 4% 2% 2% 2% Nervous System Disorders Akathisia 5% 4% 5% 7% 6% Tremor 1% 2% 2% 3% 3% Sedation 1% 2% 2% 3% 2% * Adverse reactions that occurred in ≥ 2% of brexpiprazole-treated patients and greater incidence than in placebo-treated patients Extrapyramidal Symptoms Major Depressive Disorder The incidence of reported extrapyramidal symptoms (EPS)-related adverse reactions, excluding akathisia, was 6% for brexpiprazole plus ADT-treated patients versus 3% for placebo plus ADT-treated patients. The incidence of akathisia events for brexpiprazole 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 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 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-treated patients versus 4% for placebo-treated patients. The incidence of akathisia events for brexpiprazole-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-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-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. Other Adverse Reactions Observed during the Premarketing Evaluation of Brexpiprazole Other adverse reactions (≥ 1% frequency and greater than placebo) within the short-term, placebo-controlled trials in adult patients with MDD and schizophrenia are shown below. The following listing does not include adverse reactions: 1) already listed in previous tables or elsewhere in the labeling, 2) for which a drug cause was remote, 3) which were so general as to be uninformative, 4) which were not considered to have clinically significant implications, or 5) which occurred at a rate equal to or less than placebo. Eye Disorders: Vision Blurred Gastrointestinal Disorders: Nausea, Dry Mouth, Salivary Hypersecretion, Abdominal Pain, Flatulence Infections and Infestations: Urinary Tract Infection Investigations: Blood Prolactin Increased Musculoskeletal and Connective Tissue Disorders: Myalgia Psychiatric Disorders: Abnormal Dreams, Insomnia Skin and Subcutaneous Tissue Disorders: Hyperhidrosis 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. 6.2 Postmarketing Experience The following adverse reaction has been identified during post-approval use of brexpiprazole. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Nervous System disorders: Neuroleptic Malignant Syndrome

Titrate to 2 mg once daily on Day 5 through Day 7, then to 4 mg on Day 8 based on the patient’s clinical response and tolerability. The recommended target brexpiprazole tablets dosage is 2 mg to 4 mg once daily. The maximum recommended daily dosage is 4 mg. 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. 2.3 Dosage Adjustments for Hepatic Impairment For patients with moderate to severe hepatic impairment (Child-Pugh score ≥ 7), the maximum recommended dosage is 2 mg once daily for patients with MDD, and 3 mg once daily for patients with schizophrenia [see Use in Specific Populations (8.7) , Clinical Pharmacology (12.3) ] . 2.4 Dosage Adjustments for Renal Impairment For patients with moderate, severe or end-stage renal impairment (creatinine clearance CrCl < 60 mL/minute), the maximum recommended dosage is 2 mg once daily for patients with MDD and 3 mg once daily for patients with schizophrenia [see Use in Specific Populations (8.8) , Clinical Pharmacology (12.3) ] . 2.5 Dosage 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 co-administered drug is discontinued, adjust the brexpiprazole tablets dosage to its original level. If the co-administered 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 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. *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.

Indications And Usage

1 INDICATIONS AND USAGE Brexpiprazole tablets are indicated for: Adjunctive treatment of major depressive disorder (MDD) in adults. Treatment of schizophrenia in adults. Brexpiprazole is an atypical antipsychotic indicated for: Use as an adjunctive therapy to antidepressants for the treatment of major depressive disorder (MDD) in adults. (1 , 14.1) Treatment of schizophrenia in adults.

Drug Abuse And Dependence

9 DRUG ABUSE AND DEPENDENCE 9.1 Controlled Substance Brexpiprazole is not a controlled substance. 9.2 Abuse Animals given access to brexpiprazole did not self-administer the drug, suggesting that brexpiprazole does not have rewarding properties. 9.3 Dependence Humans and animals that received chronic brexpiprazole administration did not demonstrate any withdrawal signs upon drug discontinuation. This suggests that brexpiprazole does not produce physical dependence.

Overdosage

10 OVERDOSAGE There is limited clinical trial experience regarding human overdosage with brexpiprazole. Consult a Certified Poison Control Center ( 1-800-222-1222 or www.poison.org ) for up-to-date guidance and advice regarding a brexpiprazole 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 C max 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. Hemodialysis There is no information on the effect of hemodialysis in treating an overdose with brexpiprazole; hemodialysis is unlikely to be useful because brexpiprazole is highly bound to plasma proteins.

7 DRUG INTERACTIONS Factors Dosage Adjustments for Brexpiprazole (2.5) Strong CYP2D6* orCYP3A4 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. * Brexpiprazole may be administered without dosage adjustment in patients with MDD when administered with strong CYP2D6 inhibitors (e.g., paroxetine, fluoxetine). 7.1 Drugs Having Clinically Important Interactions with Brexpiprazole Table 9: Clinically Important Drug Interactions with Brexpiprazole Strong CYP3A4 Inhibitors Clinical Impact: Concomitant use of brexpiprazole with strong CYP3A4 inhibitors increased the exposure of brexpiprazole compared to the use of brexpiprazole alone [see Clinical Pharmacology (12.3) ]. Intervention: With concomitant use of brexpiprazole with a strong CYP3A4 inhibitor, reduce the brexpiprazole dosage [see Dosage and Administration (2.5) ]. Strong CYP2D6 Inhibitors* Clinical Impact: Concomitant use of brexpiprazole with strong CYP2D6 inhibitors increased the exposure of brexpiprazole compared to the use of brexpiprazole alone [see Clinical Pharmacology (12.3) ]. Intervention: With concomitant use of brexpiprazole with a strong CYP2D6 inhibitor, reduce the brexpiprazole dosage [see Dosage and Administration (2.5) ]. Both CYP3A4 Inhibitors and CYP2D6 Inhibitors Clinical Impact: Concomitant use of brexpiprazole 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 alone [see Clinical Pharmacology (12.3) ]. Intervention: With concomitant use of brexpiprazole 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 dosage [see Dosage and Administration (2.5) ]. Strong CYP3A4 Inducers Clinical Impact: Concomitant use of brexpiprazole and a strong CYP3A4 inducer decreased the exposure of brexpiprazole compared to the use of brexpiprazole alone [see Clinical Pharmacology (12.3) ]. Intervention: With concomitant use of brexpiprazole with a strong CYP3A4 inducer, increase the brexpiprazole dosage [see Dosage and Administration (2.5) ]. * In the clinical trials examining the adjunctive use of brexpiprazole 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 may be administered without dosage adjustment in patients with MDD. 7.2 Drugs Having No Clinically Important Interactions with Brexpiprazole Based on pharmacokinetic studies, no dosage adjustment of brexpiprazole 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.

Clinical Pharmacology

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-HT 1A and dopamine D 2 receptors, and antagonist activity at serotonin 5-HT 2A receptors. 12.2 Pharmacodynamics Brexpiprazole has affinity (expressed as K i ) for multiple monoaminergic receptors including serotonin 5-HT 1A (0.12 nM), 5-HT 2A (0.47 nM), 5-HT 2B (1.9 nM), 5-HT 7 (3.7 nM), dopamine D 2 (0.30 nM), D 3 (1.1 nM), and noradrenergic α 1A (3.8 nM), α 1B (0.17 nM), α 1D (2.6 nM), and α 2C (0.59 nM) receptors. Brexpiprazole acts as a partial agonist at the 5-HT 1A , D 2 , and D 3 receptors and as an antagonist at 5-HT 2A , 5-HT 2B , 5-HT 7 , α 1A , α 1B , α 1D , and α 2C receptors. Brexpiprazole also exhibits affinity for histamine H 1 receptor (19 nM) and for muscarinic M 1 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 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 C max or AUC of brexpiprazole. After single and multiple once daily dose administration, brexpiprazole exposure (C max 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 [ 14 C]-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, 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. Figure 1: Effect of Intrinsic Factors on Brexpiprazole Pharmacokinetics 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. Drug Interaction Studies Effect 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) ]. Figure 2: The Effect of Other Drugs on Brexpiprazole Pharmacokinetics The effect of brexpiprazole on the exposures of other drugs are summarized in Figure 3.

After multiple once-daily administrations of brexpiprazole, 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.

Carcinogenesis And Mutagenesis And Impairment Of Fertility

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, 2 and 5 mg/kg/day (0.9 to 6.1 times the oral MRHD of 4 mg/day based on mg/m 2 body surface area) and to male and female rats at doses of 1, 3, and 10 mg/kg and 3, 10, 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, 3 or 30 mg/kg/day (0.7, 7.3, and 73 times the oral MRHD on a mg/m 2 basis) prior to mating with untreated males and continuing through conception and implantation. Estrus cycle irregularities and decreased fertility were observed at 3 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, 10, or 100 mg/kg/day (7.3, 24 and 240 times the oral MRHD on a mg/m 2 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.

Clinical Studies

14 CLINICAL STUDIES 14.1 Adjunctive Treatment of Major Depressive Disorder The efficacy of brexpiprazole 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 2 mg once a day or placebo. Patients in Study 227 (hereafter “Study 2”) were randomized to brexpiprazole 1 mg or 3 mg once a day or placebo. For patients randomized to brexpiprazole, all patients initiated treatment at 0.5 mg once daily during Week 1. At Week 2, the brexpiprazole 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-item 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 (plus ADT) 2 mg/day and 3 mg/day were superior to placebo plus ADT in reducing mean MADRS total scores. Results from the primary efficacy parameters for both fixed dose trials are shown below in Table 10. Figure 4 below shows the time course of response based on the primary efficacy measure (MADRS) in Study 1. Table 10: Summary of Efficacy Results for Studies 1 and 2 for the Adjunctive Treatment of MDD in Adults Study Treatment Group N Primary Efficacy Measure: MADRS Mean Baseline Score (SD) LS Mean Change from Baseline (SE) Placebo-subtracted Difference a (95% CI) 1 Brexpiprazole (2 mg/day) + ADT* 175 26.9 (5.7) -8.4 (0.6) -3.2 (-4.9, -1.5) Placebo + ADT 178 27.3 (5.6) -5.2 (0.6) -- 2 Brexpiprazole (1 mg/day) + ADT 211 26.5 (5.6) -7.6 (0.5) -1.3 (-2.7, 0.1) Brexpiprazole (3 mg/day) + ADT 213 26.5 (5.3) -8.3 (0.5) -2.0 (-3.4, -0.5) Placebo + ADT 203 26.5 (5.2) -6.3 (0.5) -- SD: standard deviation; SE: standard error; LS Mean: least-squares mean; CI: unadjusted confidence interval. * Dosages statistically significantly superior to placebo. a Difference (drug minus placebo) in least-squares mean change from baseline. An examination of population subgroups did not suggest differential response based on age, gender, race or choice of prospective antidepressant. Figure 4: Change from Baseline in MADRS Total Score by Study Visit (Week) in Patients with MDD in Adults (Study 1) nh 14.2 Schizophrenia The efficacy of brexpiprazole 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 2 mg or 4 mg once per day or placebo. Patients in the brexpiprazole groups initiated treatment at 1 mg once daily on Days 1 to 4. The brexpiprazole 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-item scale that measures positive symptoms of schizophrenia (7 items), negative symptoms of schizophrenia (7 items), and general psychopathology (16 items), 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 at both 2 mg/day and 4 mg/day was superior to placebo on the PANSS total score. In Study 4, brexpiprazole 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. Examination of population subgroups based on age, gender and race did not suggest differential responsiveness.

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 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 (N=202). They were then randomized in the double-blind treatment phase to either continue brexpiprazole 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 ≥ 5 (minimally worse) and an increase to a score > 4 on PANSS conceptual disorganization, hallucinatory behavior, suspiciousness, or unusual thought content items, with either a ≥ 2 increase on a specific item or ≥ 4 point increase on the combined four PANSS items, 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 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 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-treated patients compared with placebo group. Figure 6: Kaplan-Meier Estimation of Percent Impending Relapse in Study 5 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. yu yu

Clinical Studies Table

Geriatric Use

8.5 Geriatric Use Clinical studies of the efficacy of brexpiprazole 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 is not approved for the treatment of patients with dementia-related psychosis [see Boxed Warning , Warnings and Precautions (5.1) ] .

Pediatric Use

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.

Pregnancy

8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to brexpiprazole 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 in pregnant women to inform drug-associated risks. However, neonates whose mothers are exposed to antipsychotic drugs, like brexpiprazole, 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/m 2 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, 10, and 30 mg/kg/day (7.3, 24, and 73 times the MRHD on a mg/m 2 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, 30, 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, 10, 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.

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 and any potential adverse effects on the breastfed infant from brexpiprazole 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) ] .

Antipsychotic drugs increase the risk of death in elderly patients with dementia-related psychosis. Brexpiprazole is not approved for the treatment of patients with dementia-related psychosis [see Boxed Warning , Warnings and Precautions (5.1) ] . 8.6 CYP2D6 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) ] . 8.7 Hepatic Impairment Reduce the maximum recommended dosage in patients with moderate to severe hepatic impairment (Child-Pugh score ≥ 7). Patients with moderate to severe hepatic impairment (Child-Pugh score ≥ 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-associated adverse reactions [see Dosage and Administration ( 2.3) ]. 8.8 Renal Impairment Reduce the maximum recommended dosage in patients with moderate, severe, or end-stage renal impairment (CrCl < 60 mL/minute). Patients with impaired renal function (CrCl < 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-associated adverse reactions [see Dosage and Administration (2.4) ] . 8.9 Other Specific Populations No dosage adjustment for brexpiprazole is required on the basis of a patient’s sex, race, or smoking status [see Clinical Pharmacology ( 12.3 ) ] .
