onsider increasing the aristada dose [see dosage and administration ( 2.4 )]. examples: carbamazepine, rifampin antihypertensive drugs clinical impact: due to its alpha adrenergic antagonism, aripiprazole has the potential to enhance the effect of certain antihypertensive agents. intervention: monitor blood pressure and adjust dose accordingly [see warnings and precautions ( 5.8 )] . examples: carvedilol, lisinopril, prazosin benzodiazepines clinical impact: the intensity of sedation was greater with the combination of oral aripiprazole and lorazepam as compared to that observed with aripiprazole alone. the orthostatic hypotension observed was greater with the combination as compared to that observed with lorazepam alone [see warnings and precautions ( 5.8 )]. intervention: monitor sedation and blood pressure. adjust dose accordingly. example: lorazepam 7.2 drugs having no clinically important interactions with aristada based on pharmacokinetic studies with oral aripiprazole, no dosage adjustment of aristada is required when administered concomitantly with famotidine, valproate, or lithium [see clinical pharmacology ( 12.3 )] . in addition, no dosage adjustment is necessary for substrates of cyp2d6 (e.g., dextromethorphan, fluoxetine, paroxetine, or venlafaxine), cyp2c9 (e.g., warfarin), cyp2c19 (e.g., omeprazole, warfarin, escitalopram), or cyp3a4 (e.g., dextromethorphan) when co-administered with aristada. additionally, no dosage adjustment is necessary for valproate, lithium, lamotrigine, or sertraline when co-administered with aristada [see clinical pharmacology ( 12.3 )] .

agranulocytosis : perform complete blood counts in patients with a history of a clinically significant low white blood cell (wbc) count. consider discontinuation if clinically significant decline in wbc in the absence of other causative factors ( 5.10 ). seizures : use cautiously in patients with a history of seizures or with conditions that lower the seizure threshold ( 5.11 ). potential for cognitive and motor impairment : use caution when operating machinery ( 5.12 ). 5.1 increased 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. observational studies suggest that, similar to atypical antipsychotic drugs, treatment with conventional antipsychotic drugs may increase mortality. the extent to which the findings of increased mortality in observational studies may be attributed to the antipsychotic drug as opposed to some characteristic(s) of the patients is not clear. aristada is not approved for the treatment of patients with dementia-related psychosis [see boxed warning , warnings and precautions ( 5.2 )]. 5.2 cerebrovascular adverse reactions, including stroke in placebo-controlled trials with risperidone, aripiprazole, and olanzapine in elderly patients with dementia, there was a higher incidence of cerebrovascular adverse reactions (cerebrovascular accidents and transient ischemic attacks) including fatalities compared to placebo-treated patients. aristada is not approved for the treatment of patients with dementia-related psychosis [see boxed warning , warnings and precautions ( 5.1 )]. 5.3 potential for dosing and medication errors medication errors, including substitution and dispensing errors, between aristada and aristada initio could occur. aristada initio is for single administration in contrast to aristada which is administered monthly, every 6 weeks, or every 8 weeks [see dosage and administration ( 2.1 )] . do not substitute aristada initio for aristada because of differing pharmacokinetic profiles [see clinical pharmacology ( 12.3 )]. 5.4 neuroleptic malignant syndrome a potentially fatal symptom complex sometimes referred to as neuroleptic malignant syndrome (nms) may occur in association with antipsychotic drugs, including aristada. clinical manifestations of nms are hyperpyrexia, muscle rigidity, altered mental status, and evidence of autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis, and cardiac dysrhythmia). additional signs may include elevated creatine phosphokinase, myoglobinuria (rhabdomyolysis), and acute renal failure. the diagnostic evaluation of patients with this syndrome is complicated. in arriving at a diagnosis, it is important to identify cases in which the clinical presentation includes both serious medical illness (e.g., pneumonia, systemic infection, etc.) and untreated or inadequately treated extrapyramidal signs and symptoms (eps). other important considerations in the differential diagnosis include central anticholinergic toxicity, heat stroke, drug fever, and primary central nervous system pathology. the management of nms should include: (1) immediate discontinuation of antipsychotic drugs and other drugs not essential to concurrent therapy; (2) intensive symptomatic treatment and medical monitoring; and (3) treatment of any concomitant serious medical problems for which specific treatments are available. there is no general agreement about specific pharmacological treatment regimens for uncomplicated nms. if a patient appears to require antipsychotic drug treatment after recovery from nms, reintroduction of drug therapy should be closely monitored, since recurrences of nms have been reported. 5.5 tardive dyskinesia a syndrome of potentially irreversible, involuntary, dyskinetic movements may develop in patients treated with antipsychotic drugs. although the prevalence of the syndrome appears to be highest among the elderly, especially elderly women, it is impossible to predict which patients will develop the syndrome. whether antipsychotic drug products differ in their potential to cause tardive dyskinesia is unknown. the risk of developing tardive dyskinesia and the likelihood that it will become irreversible appear to increase as the duration of treatment and the total cumulative dose of antipsychotic drugs administered to the patient increase, but the syndrome can develop after relatively brief treatment periods at low doses, although this is uncommon. tardive dyskinesia may remit, partially or completely, if antipsychotic treatment is withdrawn. antipsychotic treatment itself may suppress (or partially suppress) the signs and symptoms of the syndrome and may thus mask the underlying process. the effect of symptomatic suppression on the long-term course of the syndrome is unknown. given these considerations, aristada should be prescribed in a manner that is most likely to minimize the occurrence of tardive dyskinesia. chronic antipsychotic treatment should generally be reserved for patients who suffer from a chronic illness that is known to respond to antipsychotic drugs. in patients who do require chronic treatment, the smallest dose and the shortest duration of treatment producing a satisfactory clinical response should be sought. the need for continued treatment should be reassessed periodically. if signs and symptoms of tardive dyskinesia appear in a patient treated with aristada drug discontinuation should be considered. however, some patients may require treatment with aristada despite the presence of the syndrome. 5.6 metabolic changes atypical antipsychotic drugs have been associated with metabolic changes that include hyperglycemia/diabetes mellitus, dyslipidemia, and weight gain. while all drugs in the class have been shown to produce some metabolic changes, each drug has its own specific risk profile. hyperglycemia/ 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 oral aripiprazole. assessment of the relationship between atypical antipsychotic use and glucose abnormalities is complicated by the possibility of an increased background risk of diabetes mellitus in patients with schizophrenia and the increasing incidence of diabetes mellitus in the general population. given these confounders, the relationship between atypical antipsychotic use and hyperglycemia-related adverse events is not completely understood. however, epidemiological studies suggest an increased risk of hyperglycemia-related adverse reactions in patients treated with the atypical antipsychotics. patients with an established diagnosis of diabetes mellitus who are started on atypical antipsychotics should be monitored regularly for worsening of glucose control. patients with risk factors for diabetes mellitus (e.g., obesity, family history of diabetes) who are starting treatment with atypical antipsychotics should undergo fasting blood glucose testing at the beginning of treatment and periodically during treatment. any patient treated with atypical antipsychotics should be monitored for symptoms of hyperglycemia including polydipsia, polyuria, polyphagia, and weakness. patients who develop symptoms of hyperglycemia during treatment with atypical antipsychotics should undergo fasting blood glucose testing. in some cases, hyperglycemia has resolved when the atypical antipsychotic was discontinued; however, some patients require continuation of anti-diabetic treatment despite discontinuation of the suspect drug. in the long-term, open-label schizophrenia study with aristada, 14% of patients with normal hemoglobin a1c (<5.7%) at baseline developed elevated levels (?5.7%) post-baseline. dyslipidemia undesirable alterations in lipids have been observed in patients treated with atypical antipsychotics. in the long-term, open-label schizophrenia study with aristada, shifts in baseline fasting total cholesterol from normal (<200 mg/dl) to high (?240 mg/dl) were reported in 1% of patients; shifts in baseline fasting ldl cholesterol from normal (<100 mg/dl) to high (?160 mg/dl) were reported in 1% of patients; and shifts in baseline fasting triglycerides from normal (<150 mg/dl) to high (?200 mg/dl) were reported in 8% of patients. in the same study, shifts in baseline fasting total cholesterol from borderline (? 200 mg/dl and <240 mg/dl) to high (?240 mg/dl) were reported in 15% of patients; shifts in baseline fasting ldl cholesterol from borderline (?100 mg/dl and <160 mg/dl) to high (?160 mg/dl) were reported in 8% of patients; and shifts in baseline fasting triglycerides from borderline (?150 mg/dl and <200 mg/dl) to high (?200 mg/dl) were reported in 35% of patients. in addition, the proportion of patients with shifts in fasting hdl cholesterol from normal (?40 mg/dl) to low (<40 mg/dl) was reported in 15% of patients. weight gain weight gain has been observed with atypical antipsychotic use. clinical monitoring of weight is recommended. the proportion of adult patients with weight gain ?7% of body weight is presented in table 7 . table 7: proportion of adult patients with shifts in weight in the 12-week, placebo-controlled, fixed-dose schizophrenia trial placebo n = 207 (%) aristada 441 mg n = 207 (%) 882 mg n = 208 (%) weight gain ?7% increase from baseline 6 10 9 5.7 pathological 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 aripiprazole. 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 aripiprazole. it should be noted that impulse-control symptoms can be associated with the underlying disorder. 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 for the patient and others if not recognized. consider dose reduction or stopping the medication if a patient develops such urges. 5.8 orthostatic hypotension aripiprazole may cause orthostatic hypotension, perhaps due to its ? 1 -adrenergic receptor antagonism. associated adverse reactions related to orthostatic hypotension can include dizziness, lightheadedness and tachycardia. generally, these risks are greatest at the beginning of treatment and during dose escalation. patients at increased risk of these adverse reactions or at increased risk of developing complications from hypotension include those with dehydration, hypovolemia, treatment with antihypertensive medication, history of cardiovascular disease (e.g., heart failure, myocardial infarction, ischemia, or conduction abnormalities), history of cerebrovascular disease, as well as patients who are antipsychotic-naïve. in such patients, consider using a lower starting dose, and monitor orthostatic vital signs. orthostatic hypotension was reported for one patient in the aristada 882 mg group (0.5%) and no patients in the aristada 441 mg and placebo groups in the 12-week schizophrenia efficacy study [see clinical studies ( 14 )] . in the long-term open-label schizophrenia study, orthostatic hypotension was reported for 1 (0.2%) patient treated with aristada. orthostatic hypotension was defined as a decrease in systolic blood pressure ?20 mmhg accompanied by an increase in heart rate ?25 bpm when comparing standing to supine values. 5.9 falls antipsychotics including aristada may cause somnolence, postural hypotension, or 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 those patients on long-term antipsychotic therapy. 5.10 leukopenia, neutropenia, and agranulocytosis in clinical trials and/or postmarketing experience, events of leukopenia and neutropenia have been reported temporally related to antipsychotic agents. agranulocytosis has also been reported. possible risk factors for leukopenia/neutropenia include pre-existing low white blood cell count (wbc)/absolute neutrophil count (anc) and history of drug-induced leukopenia/neutropenia. in patients with a history of a clinically significant low wbc/anc or drug-induced leukopenia/neutropenia, perform a complete blood count (cbc) frequently during the first few months of therapy. in such patients, consider discontinuation of aristada at the first sign of a clinical 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 aristada in patients with severe neutropenia (absolute neutrophil count <1000/mm 3 ) and follow their wbc until recovery. 5.11 seizures as with other antipsychotic drugs, use aristada cautiously 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 a population of 65 years or older. 5.12 potential for cognitive and motor impairment aristada, like other antipsychotics, has the potential to impair judgment, thinking or motor skills. patients should be cautioned about operating hazardous machinery, including automobiles, until they are reasonably certain that therapy with aristada does not affect them adversely. 5.13 body temperature regulation disruption of the body's ability to reduce core body temperature has been attributed to antipsychotic agents. appropriate care is advised when prescribing aristada for patients who will be experiencing conditions which may contribute to an elevation in core body temperature, (e.g., exercising strenuously, exposure to extreme heat, receiving concomitant medication with anticholinergic activity, or being subject to dehydration). 5.14 dysphagia esophageal dysmotility and aspiration have been associated with antipsychotic drug use. aristada and other antipsychotic drugs should be used cautiously in patients at risk for aspiration pneumonia.

ing cyp3a4 inhibitors, cyp2d6 inhibitors, or cyp3a4 inducers for more than 2 weeks ( 2.4 ). 2.1 recommended dosage aristada is only to be administered as an intramuscular injection by a healthcare professional. for patients who have never taken aripiprazole, establish tolerability with oral aripiprazole prior to initiating treatment with aristada. due to the half-life of oral aripiprazole, it may take up to 2 weeks to fully assess tolerability. refer to the prescribing information of oral aripiprazole for the recommended dosage and administration of the oral formulation. there are two ways to initiate treatment with aristada: option #1: administer one intramuscular injection of aristada initio 675 mg (in either the deltoid or gluteal muscle) and one dose of oral aripiprazole 30 mg in conjunction with the first aristada injection. the first aristada injection may be administered on the same day as aristada initio or up to 10 days thereafter. see the aristada initio prescribing information for additional information regarding administration of aristada initio. avoid injecting both aristada initio and aristada concomitantly into the same deltoid or gluteal muscle. option #2: administer 21 consecutive days of oral aripiprazole in conjunction with the first aristada injection. depending on individual patient's needs, treatment with aristada can be initiated at a dose of 441 mg, 662 mg or 882 mg administered monthly, 882 mg administered every 6 weeks or 1064 mg administered every 2 months. the 441 mg, 662 mg, 882 mg and 1064 mg doses correspond to 300 mg, 450 mg, 600 mg and 724 mg of aripiprazole, respectively [see clinical pharmacology ( 12.3 )]. table 1: aristada dosing frequency and site of injection dose dosing frequency site of intramuscular injection 441 mg monthly deltoid or gluteal 662 mg monthly gluteal 882 mg monthly or every 6 weeks gluteal 1064 mg every 2 months gluteal use the following aristada doses for patients who are stabilized on oral aripiprazole, as shown in table 2 . table 2: aristada doses based on oral aripiprazole total daily dose oral aripiprazole dose intramuscular aristada dose 10 mg per day 441 mg every month 15 mg per day 662 mg every month 882 mg every 6 weeks 1064 mg every 2 months 20 mg or higher per day 882 mg every month in conjunction with the first aristada injection, administer a single injection of aristada initio and one dose of oral aripiprazole 30 mg, or continue treatment with oral aripiprazole for 21 consecutive days [see recommended dosage ( 2.1 )]. adjust the aristada dose as needed. when making dose and dosing interval adjustments, consider the pharmacokinetics and prolonged-release characteristics of aristada [see clinical pharmacology ( 12.3 )]. 2.2 missed doses when a dose of aristada is missed, administer the next injection of aristada as soon as possible. depending on the time elapsed since the last aristada injection, supplement the next aristada injection as recommended in table 3 below. table 3: recommendation for concomitant supplementation following missed doses of aristada dose of patient's last aristada injection length of time since last injection a the patient should supplement with the same dose of oral aripiprazole as when the patient began aristada (see table 2 ). 441 mg ? 6 weeks > 6 and ? 7 weeks > 7 weeks 662 mg ? 8 weeks > 8 and ? 12 weeks > 12 weeks 882 mg ? 8 weeks > 8 and ? 12 weeks > 12 weeks 1064 mg ? 10 weeks > 10 and ? 12 weeks > 12 weeks dosage and administration for re-initiation of aristada no supplementation required supplement with a single dose of aristada initio or 7 days of oral aripiprazole a re-initiate with a single dose of aristada initio and a single dose of oral aripiprazole 30 mg or supplement with 21 days of oral aripiprazole a 2.3 early dosing the recommended aristada dosing interval is monthly for the 441 mg, 662 mg and 882 mg doses, every 6 weeks for the 882 mg dose, or every 2 months for the 1064 mg dose and should be maintained. in the event of early dosing, an aristada injection should not be given earlier than 14 days after the previous injection. 2.4 dose adjustments for cyp450 considerations refer to the prescribing information for oral aripiprazole for recommendations regarding dosage adjustments due to drug interactions, for the first 21 days when the patient is taking 21 days of oral aripiprazole concomitantly with the first dose of aristada. avoid initiating aristada treatment with aristada initio in patients requiring dose adjustments. once stabilized on aristada, refer to the dosing recommendations below for patients taking strong cyp2d6 inhibitors, strong cyp3a4 inhibitors, or strong cyp3a4 inducers: no dosage changes recommended for aristada, if cyp450 modulators are added for less than 2 weeks. make dose changes to aristada if cyp450 modulators are added for greater than 2 weeks (see table 4 ). table 4: aristada dose adjustments with concomitant cyp450 modulator use concomitant medicine dose change for aristada a a for the 882 mg dose administered every 6 weeks and the 1064 mg administered every 2 months, the next lower strength should be 441 mg administered monthly. strong cyp3a4 inhibitor reduce the dose of aristada to the next lower strength. no dosage adjustment is necessary in patients taking 441 mg aristada, if tolerated. for patients known to be poor metabolizers of cyp2d6 : reduce dose to 441 mg from 662 mg, 882 mg, or 1064 mg. no dosage adjustment is necessary in patients taking 441 mg aristada, if tolerated. strong cyp2d6 inhibitor reduce the dose of aristada to the next lower strength. no dosage adjustment is necessary in patients taking 441 mg aristada, if tolerated. for patients known to be poor metabolizers of cyp2d6 : no dose adjustment required. both strong cyp3a4 inhibitor and strong cyp2d6 inhibitor avoid use for patients at 662 mg, 882 mg, or 1064 mg dose. no dosage adjustment is necessary in patients taking 441 mg aristada, if tolerated. cyp3a4 inducers no dose adjustment for 662 mg, 882 mg, or 1064 mg dose; increase the 441 mg dose to 662 mg. 2.5 important administration instructions the

3 )] dysphagia [see warnings and precautions ( 5.14 )] most commonly observed adverse reaction with aristada (incidence ?5% and at least twice that for placebo) was akathisia ( 6.1 ). to report suspected adverse reactions, contact alkermes, inc. at 1-866-274-7823 or fda at 1-800-fda-1088 or www.fda.gov/medwatch . 6.1 clinical studies 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 practice. aristada patient exposure aristada has been evaluated for safety in 1180 adult patients in clinical trials in schizophrenia. commonly observed adverse reactions the most common adverse reaction (incidence ?5% and at least twice the rate of placebo in patients treated with aristada) was akathisia. adverse reactions occurring at an incidence of 2% or more in aristada-treated patients adverse reactions associated with the use of aristada (incidence of 2% or greater, rounded to the nearest percent and aristada incidence greater than placebo) that occurred are shown in table

dose groups. injection site reactions injection site reactions were reported by 4% of patients treated with 441 mg aristada and 5% of patients treated with 882 mg aristada compared to 2% of patients treated with placebo. most of these were injection site pain (3%, 4% and 2% in the 441 mg aristada, 882 mg aristada and placebo groups, respectively) and most were associated with the first injection, and decreased with each subsequent injection to less than or equal to 1% for both doses of aristada and placebo. other injection site reactions (induration, swelling and redness) occurred at less than

of oral aripiprazole. because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or to establish a causal relationship to drug exposure: occurrences of allergic reaction (anaphylactic reaction, angioedema, laryngospasm, pruritus/urticaria, or oropharyngeal spasm), pathological gambling, hiccups, blood

onsider increasing the aristada dose [see dosage and administration ( 2.4 )]. examples: carbamazepine, rifampin antihypertensive drugs clinical impact: due to its alpha adrenergic antagonism, aripiprazole has the potential to enhance the effect of certain antihypertensive agents. intervention: monitor blood pressure and adjust dose accordingly [see warnings and precautions ( 5.8 )] . examples: carvedilol, lisinopril, prazosin benzodiazepines clinical impact: the intensity of sedation was greater with the combination of oral aripiprazole and lorazepam as compared to that observed with aripiprazole alone. the orthostatic hypotension observed was greater with the combination as compared to that observed with lorazepam alone [see warnings and precautions ( 5.8 )]. intervention: monitor sedation and blood pressure. adjust dose accordingly. example: lorazepam 7.2 drugs having no clinically important interactions with aristada based on pharmacokinetic studies with oral aripiprazole, no dosage adjustment of aristada is required when administered concomitantly with famotidine, valproate, or lithium [see clinical pharmacology ( 12.3 )] . in addition, no dosage adjustment is necessary for substrates of cyp2d6 (e.g., dextromethorphan, fluoxetine, paroxetine, or venlafaxine), cyp2c9 (e.g., warfarin), cyp2c19 (e.g., omeprazole, warfarin, escitalopram), or cyp3a4 (e.g., dextromethorphan) when co-administered with aristada. additionally, no dosage adjustment is necessary for valproate, lithium, lamotrigine, or sertraline when co-administered with aristada [see clinical pharmacology ( 12.3 )] .

rganogenesis at doses up to 5 and 15 times, respectively, the maximum recommended human dose (mrhd) of 1064 mg based on body surface area (mg/m 2 ). however, aripiprazole caused developmental toxicity and possible teratogenic effects in rats and rabbits [see data]. the background risk of major birth defects and miscarriage for the indicated population are unknown. in the u.s. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. advise pregnant women of the potential risk to a fetus. 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 who were exposed to antipsychotic drugs during the third trimester of pregnancy. these symptoms have varied in severity. monitor neonates for extrapyramidal and/or withdrawal symptoms and manage symptoms appropriately. some neonates recover within hours or days without specific treatment; others required prolonged hospitalization. data animal data for aripiprazole lauroxil aripiprazole lauroxil did not cause adverse developmental or maternal effects in rats or rabbits when administered intramuscularly during the period of organogenesis at doses of 18, 49, or 144 mg/animal in pregnant rats which are approximately 0.6 to 5 times the mrhd of 1064 mg on mg/m 2 basis, and at doses of 241, 723, and 2893 mg/animal in pregnant rabbits which are approximately 1 to 15 times the mrhd on mg/m 2 basis. however, aripiprazole caused developmental toxicity and possible teratogenic effects in rats and rabbits [see data below] . animal data for aripiprazole pregnant rats were treated with oral doses of 3, 10, and 30 mg/kg/day which are approximately 1 to 10 times the oral mrhd of 30 mg/day on mg/m 2 basis of aripiprazole during the period of organogenesis. treatment at the highest dose caused a slight prolongation of gestation and delay in fetal development, as evidenced by decreased fetal weight, and undescended testes. delayed skeletal ossification was observed at 3 and 10 times the oral mrhd on mg/m 2 basis. at 3 and 10 times the oral mrhd on mg/m 2 basis, delivered offspring had decreased body weights. increased incidences of hepatodiaphragmatic nodules and diaphragmatic hernia were observed in offspring from the highest dose group (the other dose groups were not examined for these findings). a low incidence of diaphragmatic hernia was also seen in the fetuses exposed to the highest dose. postnatally, delayed vaginal opening was seen at 3 and 10 times the oral mrhd on mg/m 2 basis and impaired reproductive performance (decreased fertility rate, corpora lutea, implants, live fetuses, and increased post-implantation loss, likely mediated through effects on female offspring) along with some maternal toxicity were seen at the highest dose; however, there was no evidence to suggest that these developmental effects were secondary to maternal toxicity. in pregnant rabbits treated with oral doses of 10, 30, and 100 mg/kg/day which are 2 to 11 times human exposure at the oral mrhd based on auc and 6 to 65 times the oral mrhd on mg/m 2 basis of aripiprazole during the period of organogenesis decreased maternal food consumption and increased abortions were seen at the highest dose as well as increased fetal mortality. decreased fetal weight and increased incidence of fused sternebrae were observed at 3 and 11 times the oral mrhd based on auc. in rats treated with oral doses of 3, 10, and 30 mg/kg/day which are 1 to 10 times the oral mrhd on mg/m 2 basis of aripiprazole perinatally and postnatally (from day 17 of gestation through day 21 postpartum), slight maternal toxicity and slightly prolonged gestation were seen at the highest dose. an increase in stillbirths and decreases in pup weight (persisting into adulthood) and survival were also seen at this dose. 8.2 lactation risk summary aripiprazole is present in human breast milk; however, there are insufficient data to assess the amount in human milk, the effects on the breastfed infant, or the effects on milk production. the development and health benefits of breastfeeding should be considered along with the mother's clinical need for aristada and any potential adverse effects on the breastfed infant from aristada or from the underlying maternal condition. 8.4 pediatric use safety and effectiveness of aristada in patients <18 years of age have not been evaluated. 8.5 geriatric use safety and effectiveness of aristada in patients >65 years of age have not been evaluated. elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. aristada is not approved for the treatment of patients with dementia-related psychosis [see warnings and precautions ( 5.1 , 5.2 )]. 8.6 cyp2d6 poor metabolizers dosage adjustment is recommended in known cyp2d6 poor metabolizers due to high aripiprazole concentrations. approximately 8% of caucasians and 3-8% of black/african americans cannot metabolize cyp2d6 substrates and are classified as poor metabolizers (pm) [see dosage and administration ( 2.4 ), clinical pharmacology ( 12.3 )] . 8.7 hepatic and renal impairment no dosage adjustment for aristada is required based on a patient's hepatic function (mild to severe hepatic impairment, child-pugh score between 5 and 15), or renal function (mild to severe renal impairment, glomerular filtration rate between 15 and 90 ml/minute) [see clinical pharmacology ( 12.3 )] . 8.8 other specific populations no dosage adjustment for aristada is required on the basis of a patient's sex, race, or smoking status [see clinical pharmacology ( 12.3 )] .

caused developmental toxicity and possible teratogenic effects in rats and rabbits [see data]. the background risk of major birth defects and miscarriage for the indicated population are unknown. in the u.s. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. advise pregnant women of the potential risk to a fetus. 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 who were exposed to antipsychotic drugs during the third trimester of pregnancy. these symptoms have varied in severity. monitor neonates for extrapyramidal and/or withdrawal symptoms and manage symptoms appropriately. some neonates recover within hours or days without specific treatment; others required prolonged hospitalization. data animal data for aripiprazole lauroxil aripiprazole lauroxil did not cause adverse developmental or maternal effects in rats or rabbits when administered intramuscularly during the period of organogenesis at doses of 18, 49, or 144 mg/animal in pregnant rats which are approximately 0.6 to 5 times the mrhd of 1064 mg on mg/m 2 basis, and at doses of 241, 723, and 2893 mg/animal in pregnant rabbits which are approximately 1 to 15 times the mrhd on mg/m 2 basis. however, aripiprazole caused developmental toxicity and possible teratogenic effects in rats and rabbits [see data below] . animal data for aripiprazole pregnant rats were treated with oral doses of 3, 10, and 30 mg/kg/day which are approximately 1 to 10 times the oral mrhd of 30 mg/day on mg/m 2 basis of aripiprazole during the period of organogenesis. treatment at the highest dose caused a slight prolongation of gestation and delay in fetal development, as evidenced by decreased fetal weight, and undescended testes. delayed skeletal ossification was observed at 3 and 10 times the oral mrhd on mg/m 2 basis. at 3 and 10 times the oral mrhd on mg/m 2 basis, delivered offspring had decreased body weights. increased incidences of hepatodiaphragmatic nodules and diaphragmatic hernia were observed in offspring from the highest dose group (the other dose groups were not examined for these findings). a low incidence of diaphragmatic hernia was also seen in the fetuses exposed to the highest dose. postnatally, delayed vaginal opening was seen at 3 and 10 times the oral mrhd on mg/m 2 basis and impaired reproductive performance (decreased fertility rate, corpora lutea, implants, live fetuses, and increased post-implantation loss, likely mediated through effects on female offspring) along with some maternal toxicity were seen at the highest dose; however, there was no evidence to suggest that these developmental effects were secondary to maternal toxicity. in pregnant rabbits treated with oral doses of 10, 30, and 100 mg/kg/day which are 2 to 11 times human exposure at the oral mrhd based on auc and 6 to 65 times the oral mrhd on mg/m 2 basis of aripiprazole during the period of organogenesis decreased maternal food consumption and increased abortions were seen at the highest dose as well as increased fetal mortality. decreased fetal weight and increased incidence of fused sternebrae were observed at 3 and 11 times the oral mrhd based on auc. in rats treated with oral doses of 3, 10, and 30 mg/kg/day which are 1 to 10 times the oral mrhd on mg/m 2 basis of aripiprazole perinatally and postnatally (from day 17 of gestation through day 21 postpartum), slight maternal toxicity and slightly prolonged gestation were seen at the highest dose. an increase in stillbirths and decreases in pup weight (persisting into adulthood) and survival were also seen at this dose.

ciable affinity for cholinergic muscarinic receptors (ic 50 > 1000 nm). actions at receptors other than d 2 , 5-ht 1a , and 5-ht 2a could explain some of the adverse reactions of aripiprazole (e.g., the orthostatic hypotension observed with aripiprazole may be explained by its antagonist activity at adrenergic alpha 1 receptors). 12.3 pharmacokinetics aristada is a prodrug of aripiprazole and its activity is primarily due to aripiprazole, and to a lesser extent dehydro-aripiprazole (major metabolite of aripiprazole), which has been shown to have affinities for d 2 receptors similar to aripiprazole and represents 30-40% of the aripiprazole exposure in plasma. absorption after single intramuscular injection the appearance of aripiprazole in the systemic circulation starts from 5 to 6 days and continues to be released for an additional 36 days. aripiprazole concentrations increase with consecutive doses of aristada and reach steady-state four months following treatment initiation. the concentration-time course of dehydro-aripiprazole followed that of aripiprazole. with the addition of a single intramuscular injection of aristada initio and 30 mg oral aripiprazole at the time of the first aristada dose, aripiprazole concentrations reach relevant levels within 4 days. similarly, with the addition of the oral supplementation for 21 days at the time of the first aristada dose, aripiprazole concentrations reach relevant levels within 4 days. aripiprazole exposure was similar for deltoid and gluteal intramuscular injections of 441 mg aristada, thus are interchangeable. administration of 882 mg every 6 weeks or 1064 mg every 2 months results in plasma aripiprazole concentrations that were similar to exposure with 662 mg monthly and are within the range provided by doses of 441 mg monthly and 882 mg monthly. the doses of 441 mg monthly and 882 monthly showed a similar clinical response to each other. distribution based on population pharmacokinetic analysis, the apparent volume of distribution of aripiprazole following intramuscular injection of aristada was 268 l, indicating extensive extravascular distribution following absorption. at therapeutic concentrations, aripiprazole and its major metabolite are greater than 99% bound to serum proteins, primarily to albumin. in healthy human volunteers administered 0.5 mg/day to 30 mg/day oral aripiprazole for 14 days, there was dose-dependent d 2 receptor occupancy indicating brain penetration of aripiprazole in humans. elimination metabolism the biotransformation of aristada likely involves enzyme-mediated hydrolysis to form n-hydroxymethyl-aripiprazole, which subsequently undergoes hydrolysis to aripiprazole. elimination of aripiprazole is mainly through hepatic metabolism involving cyp3a4 and cyp2d6. [see dosage and administration ( 2.4 )]. excretion the mean aripiprazole terminal elimination half-life ranged from 53.9 days to 57.2 days after monthly, every 6-week and every 2 month injections of aristada. the significantly longer aripiprazole apparent half-life compared to oral aripiprazole (mean 75 hours) is attributed to the dissolution and formation rate-limited elimination of aripiprazole following aristada administration. drug interaction studies no specific drug interaction studies have been performed with aristada. the drug interaction data provided below is obtained from studies with oral aripiprazole. effects of other drugs on the exposures of aripiprazole and dehydro-aripiprazole are summarized in figure 1 and figure 2 , respectively. based on simulation, a 4.5-fold increase in mean c max and auc values at steady-state is expected when extensive metabolizers of cyp2d6 are administered with both strong cyp2d6 and cyp3a4 inhibitors. after oral administration, a 3-fold increase in mean c max and auc values at steady-state is expected in poor metabolizers of cyp2d6 administered with strong cyp3a4 inhibitors. figure 1: the effects of other drugs on aripiprazole pharmacokinetics figure 2: the effects of other drugs on dehydro-aripiprazole pharmacokinetics the effects of aripiprazole on the exposures of other drugs are summarized in figure 3 . figure 3: the effects of oral aripiprazole on pharmacokinetics of other drugs figure 1 figure 2 figure 3 specific population studies a population pharmacokinetic analysis showed no effect of sex, race or smoking on aristada pharmacokinetics [see use in specific populations ( 8.8 )] . exposures of aripiprazole and dehydro-aripiprazole using oral aripiprazole in specific populations are summarized in figure 4 and figure 5 , respectively. figure 4: effects of intrinsic factors on aripiprazole pharmacokinetics figure 5: effects of intrinsic factors on dehydro-aripiprazole pharmacokinetics figure 4 figure 5

entation for 21 days at the time of the first aristada dose, aripiprazole concentrations reach relevant levels within 4 days. aripiprazole exposure was similar for deltoid and gluteal intramuscular injections of 441 mg aristada, thus are interchangeable. administration of 882 mg every 6 weeks or 1064 mg every 2 months results in plasma aripiprazole concentrations that were similar to exposure with 662 mg monthly and are within the range provided by doses of 441 mg monthly and 882 mg monthly. the doses of 441 mg monthly and 882 monthly showed a similar clinical response to each other. distribution based on population pharmacokinetic analysis, the apparent volume of distribution of aripiprazole following intramuscular injection of aristada was 268 l, indicating extensive extravascular distribution following absorption. at therapeutic concentrations, aripiprazole and its major metabolite are greater than 99% bound to serum proteins, primarily to albumin. in healthy human volunteers administered 0.5 mg/day to 30 mg/day oral aripiprazole for 14 days, there was dose-dependent d 2 receptor occupancy indicating brain penetration of aripiprazole in humans. elimination metabolism the biotransformation of aristada likely involves enzyme-mediated hydrolysis to form n-hydroxymethyl-aripiprazole, which subsequently undergoes hydrolysis to aripiprazole. elimination of aripiprazole is mainly through hepatic metabolism involving cyp3a4 and cyp2d6.
