Dosage and Administration

2 DOSAGE AND ADMINISTRATION Administer ARISTADA by intramuscular injection in the deltoid (441 mg dose only) or gluteal (441 mg, 662 mg, 882 mg or 1064 mg) muscle by a healthcare professional ( 2.1 ). For patients naïve to aripiprazole, establish tolerability with oral aripiprazole prior to initiating treatment with ARISTADA ( 2.1 ). There are two options for initiating treatment with ARISTADA: Option #1: Administer one injection of 675 mg of ARISTADA INITIO ® and one 30 mg dose of oral aripiprazole in conjunction with the first ARISTADA injection. ( 2.1 ). Option #2: Administer 21 consecutive days of oral aripiprazole in conjunction with the first ARISTADA injection ( 2.1 ). ARISTADA can be initiated at a dose of 441 mg, 662 mg or 882 mg administered monthly, 882 mg dose every 6 weeks, or 1064 mg dose every 2 months ( 2.1 ). Dosing regimen adjustments may be required for missed doses ( 2.2 ). Dose adjustments are required for 1) known CYP2D6 poor metabolizers and 2) for patients taking 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 )].

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 8 .

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 1%. In an open label pharmacokinetic study evaluating 441 mg monthly, 882 mg every 6 weeks, and 1064 mg every 2 months, injection site reactions were similar across the dose groups. Extrapyramidal Symptoms In the 12-week schizophrenia efficacy study [see Clinical Studies ( 14 )] , for ARISTADA-treated patients, the incidence of other EPS-related events, excluding akathisia and restlessness, was 5% and 7% for...

Drug Interactions

7 DRUG INTERACTIONS 7.1 Drugs Having Clinically Important Interactions with ARISTADA Table 10: Clinically Important Drug Interactions with ARISTADA Strong CYP3A4 Inhibitors and CYP2D6 Inhibitors Clinical Impact: The concomitant use of oral aripiprazole with strong CYP3A4 or CYP2D6 inhibitors increased the exposure of aripiprazole compared to the use of oral aripiprazole alone [see Clinical Pharmacology ( 12.3 )]. Intervention: With concomitant use of ARISTADA with a strong CYP3A4 inhibitor or CYP2D6 inhibitor for more than 2 weeks, reduce the ARISTADA dose [see Dosage and Administration ( 2.4 )]. Examples: itraconazole, clarithromycin, quinidine, fluoxetine, paroxetine Strong CYP3A4 Inducers Clinical Impact: The concomitant use of oral aripiprazole and carbamazepine decreased the exposure of aripiprazole compared to the use of oral aripiprazole alone [see Clinical Pharmacology ( 12.3 )]. Intervention: With concomitant use of ARISTADA with a strong CYP3A4 inducer for more than 2 weeks consider 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 )] .

Contraindications

4 CONTRAINDICATIONS ARISTADA is contraindicated in patients with a known hypersensitivity reaction to aripiprazole. Hypersensitivity reactions have ranged from pruritus/urticaria to anaphylaxis [see Adverse Reactions ( 6 )]. Known hypersensitivity to aripiprazole ( 4 )

Pregnancy and Breastfeeding

8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to ARISTADA 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 Neonates exposed to antipsychotic drugs, including ARISTADA, during the third trimester of pregnancy are at risk for extrapyramidal and/or withdrawal symptoms following delivery. Limited published data on aripiprazole use in pregnant women are not sufficient to inform any drug-associated risks for birth defects or miscarriage (see Clinical Considerations ) . Overall available data from published epidemiologic studies of pregnant women exposed to aripiprazole have not established a drug-associated risk of major birth defects, miscarriage, or adverse maternal outcomes. There are risks to the mother associated with untreated schizophrenia and with exposure to antipsychotics, including ARISTADA, during pregnancy (see Clinical Considerations ) . Aripiprazole exposure during pregnancy may decrease milk supply in the post-partum period [see Use in Specific Populations ( 8.2 )] . No teratogenicity was observed in animal reproductive studies with intramuscular administration of aripiprazole lauroxil to rats and rabbits during organogenesis at doses up to 5 and 15 times, respectively, the maximum recommended human dose (MRHD) of 1,064 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 to 4% and 15 to 20%, respectively. Advise pregnant women of the potential risk to...
