AZSTARYS

1 INDICATIONS AND USAGE AZSTARYS is indicated for the treatment of Attention Deficit Hyperactivity Disorder (ADHD) in patients 6 years of age and older. Limitations of Use The use of AZSTARYS is not recommended in pediatric patients younger than 6 years of age because they had higher plasma exposure and a higher incidence of adverse reactions (e.g., weight loss) than patients 6 years and older at the same dosage [see Warnings and Precautions ( 5.7 ), Use in Specific Populations ( 8.4 )]. AZSTARYS is a central nervous system (CNS) stimulant indicated for the treatment of Attention Deficit Hyperactivity Disorder (ADHD) in patients 6 years of age and older. ( 1 ) Limitations of Use The use of AZSTARYS is not recommended in pediatric patients younger than 6 years of age because they had higher plasma exposure and a higher incidence of adverse reactions (e.g., weight loss) than patients 6 years and older at the same dosage (5.7, 8.4).

2 DOSAGE AND ADMINISTRATION Pediatric Patients 6 to 12 years : Recommended starting dosage is 39.2 mg/7.8 mg orally once daily in the morning. Dosage may be increased to 52.3 mg/10.4 mg daily or decreased to 26.1 mg/5.2 mg daily after one week. Maximum recommended dosage is 52.3 mg/10.4 mg once daily. ( 2.2 ) Adults and Pediatric Patients 13 to 17 years: Recommended starting dosage is 39.2 mg/7.8 mg orally once daily in the morning. Increase the dosage after one week to 52.3 mg/10.4 mg once daily depending on response and tolerability. ( 2.2 ) Administer with or without food. ( 2.3 ) Swallow capsules whole or open and sprinkle onto applesauce or add to water. ( 2.3 ) To avoid substitution errors and overdosage, do not substitute for other methylphenidate products on a milligram-per-milligram basis. ( 2.4 ) 2.1 Pretreatment Screening Prior to treating patients with AZSTARYS, assess: for the presence of cardiac disease (i.e., perform a careful history, family history of sudden death or ventricular arrhythmia, and physical exam) [see Warnings and Precautions ( 5.2 )]. the family history and clinically evaluate patients for motor or verbal tics or Tourette’s syndrome before initiating AZSTARYS [see Warnings and Precautions ( 5.10 )]. 2.2 Recommended Dosage Pediatric Patients 6 to 12 years of age The recommended starting dosage of AZSTARYS is 39.2 mg serdexmethylphenidate/7.8 mg dexmethylphenidate once daily in the morning. The dosage may be increased after one week to a dosage of 52.3 mg serdexmethylphenidate/10.4 mg dexmethylphenidate per day, or decreased after one week to a dosage of 26.1 mg serdexmethylphenidate/5.2 mg dexmethylphenidate per day, depending on response and tolerability. Maximum recommended dosage is 52.3 mg serdexmethylphendiate/10.4 mg dexmethyphenidate once daily. Adults and Pediatric Patients 13 to 17 years of age The recommended starting dosage of AZSTARYS is 39.2 mg serdexmethylphenidate/7.8 mg dexmethylphenidate once daily in the morning. Increase the dosage after one week to a dosage of 52.3 mg serdexmethylphenidate/10.4 mg dexmethylphenidate per day, depending on response and tolerability. Maximum recommended dosage is 52.3 mg serdexmethylphenidate/10.4 mg dexmethylphenidate once daily. 2.3 Administration Instructions Administer AZSTARYS orally once daily in the morning with or without food [see Clinical Pharmacology ( 12.3 )] . AZSTARYS capsules may be taken whole, or opened and the entire contents sprinkled into 50 mL of water or over 2 tablespoons of applesauce. Consume all the drug/food mixture immediately or within 10 minutes of mixing; do not store for future use [see Clinical Pharmacology ( 12.3 )] . 2.4 Switching from Other Methylphenidate Products If switching from other methylphenidate products, discontinue that treatment, and titrate with AZSTARYS using the titration schedule described above. Do not substitute AZSTARYS for other methylphenidate products on a milligram-per-milligram basis because these products have different pharmacokinetic profiles from AZSTARYS and may have different methylphenidate base composition [see Description ( 11 ), Clinical Pharmacology ( 12.3 )] . 2.5 Dosage Reduction and Discontinuation If paradoxical aggravation of symptoms or other adverse reactions occur, reduce dosage or, if necessary, discontinue AZSTARYS. If improvement is not observed after appropriate dosage adjustment over a one-month period, discontinue AZSTARYS.

4 CONTRAINDICATIONS AZSTARYS is contraindicated in patients: with known hypersensitivity to serdexmethylphenidate, methylphenidate, or other components of AZSTARYS. Bronchospasm, rash, and pruritus have been reported in patients who received AZSTARYS. Hypersensitivity reactions such as angioedema and anaphylactic reactions have been reported in patients treated with other methylphenidate products [see Adverse Reactions ( 6.2 )] . receiving concomitant treatment with monoamine oxidase inhibitors (MAOIs), or within 14 days following discontinuation of treatment with an MAOI, because of the risk of hypertensive crisis [see Drug Interactions ( 7.1 )] . Known hypersensitivity to serdexmethylphenidate, methylphenidate, or product components. ( 4 ) Concurrent treatment with a monoamine oxidase inhibitor (MAOI), or use of an MAOI within the preceding 14 days. ( 4 )

5 WARNINGS AND PRECAUTIONS Risks to Patients with Serious Cardiac Disease : Avoid use in patients with known structural cardiac abnormalities, cardiomyopathy, serious cardiac arrhythmias, coronary artery disease, or other serious cardiac disease. (5.2) Increased Blood Pressure and Heart Rate : Monitor blood pressure and pulse. (5.3) Psychiatric Adverse Reactions : Prior to initiating AZSTARYS, screen patients for risk factors for developing a manic episode. If new psychotic or manic symptoms occur, consider discontinuing AZSTARYS. (5.4) Priapism : If abnormally sustained or frequent and painful erections occur, patients should seek immediate medical attention. (5.5) Peripheral Vasculopathy, including Raynaud's Phenomenon : Careful observation for digital changes is necessary during AZSTARYS treatment with ADHD stimulants. Further clinical evaluation (e.g., rheumatology referral) may be appropriate for patients who develop signs or symptoms of peripheral vasculopathy. (5.6) Long-Term Suppression of Growth in Pediatric Patients : Monitor height and weight at appropriate intervals in pediatric patients. (5.7) Acute Angle Closure Glaucoma : AZSTARYS-treated patients considered at risk for acute angle closure glaucoma (e.g., patients with significant hyperopia) should be evaluated by an ophthalmologist. (5.8) Increased Intraocular Pressure (IOP) and Glaucoma : Prescribe AZSTARYS to patients with open-angle glaucoma or abnormally increased IOP only if the benefit of treatment is considered to outweigh the risk. Closely monitor patients with a history of increased IOP or open angle glaucoma. (5.9) Motor and Verbal Tics, and Worsening of Tourette’s Syndrome: Before initiating AZSTARYS, assess the family history and clinically evaluate patients for tics or Tourette’s syndrome. Regularly monitor patients for the emergence or worsening of tics or Tourette’s syndrome. Discontinue treatment if clinically appropriate. (5.10) 5.1 Abuse, Misuse, and Addiction AZSTARYS has a high potential for abuse and misuse. The use of AZSTARYS exposes individuals to the risks of abuse and misuse, which can lead to the development of a substance use disorder, including addiction. AZSTARYS can be diverted for non-medical use into illicit channels or distribution [see Drug Abuse and Dependence (9.2) ] . Misuse and abuse of CNS stimulants, including AZSTARYS, can result in overdose and death [see Overdosage ( 10 )], and this risk is increased with higher doses or unapproved methods of administration, such as snorting or injection. Before prescribing AZSTARYS, assess each patient’s risk for abuse, misuse, and addiction. Educate patients and their families about these risks and proper disposal of any unused drug. Advise patients to store AZSTARYS in a safe place, preferably locked, and instruct patients to not give AZSTARYS to anyone else. Throughout AZSTARYS treatment, reassess each patient’s risk of abuse, misuse, and addiction and frequently monitor for signs and symptoms of abuse, misuse, and addiction. 5.2 Risks to Patients with Serious Cardiac Disease Sudden death has been reported in patients with structural cardiac abnormalities or other serious cardiac disease who were treated with CNS stimulants at the recommended ADHD dosage. Avoid AZSTARYS use in patients with known structural cardiac abnormalities, cardiomyopathy, serious cardiac arrhythmia, coronary artery disease, or other serious cardiac disease. 5.3 Increased Blood Pressure and Heart Rate CNS stimulants cause an increase in blood pressure (mean increase approximately 2 to 4 mmHg) and heart rate (mean increase approximately 3 to 6 beats per minute). Some patients may have larger increases. Monitor all AZSTARYS-treated patients for hypertension and tachycardia. 5.4 Psychiatric Adverse Reactions Exacerbation of Pre-Existing Psychosis CNS stimulants may exacerbate symptoms of behavior disturbance and thought disorder in patients with a pre-existing psychotic disorder. Induction of a Manic Episode in Patients with Bipolar Disorder CNS stimulants may induce a manic or mixed mood episode in patients. Prior to initiating AZSTARYS treatment, screen patients for risk factors for developing a manic episode (e.g., comorbid or history of depressive symptoms or a family history of suicide, bipolar disorder, or depression). New Psychotic or Manic Symptoms CNS stimulants, at the recommended dosage, may cause psychotic or manic symptoms (e.g., hallucinations, delusional thinking, or mania) in patients without a prior history of psychotic illness or mania. In a pooled analysis of multiple short-term, placebo-controlled studies of CNS stimulants, psychotic or manic symptoms occurred in approximately 0.1% of CNS stimulant-treated patients, compared to 0% of placebo-treated patients. If such symptoms occur, consider discontinuing AZSTARYS. 5.5 Priapism Prolonged and painful erections, sometimes requiring surgical intervention, have been reported with methylphenidate use, in both adult and pediatric male patients. Although priapism was not reported with methylphenidate initiation, it developed after some time on methylphenidate, often subsequent to an increase in dosage. Priapism also occurred during methylphenidate withdrawal (drug holidays or during discontinuation). AZSTARYS-treated patients who develop abnormally sustained or frequent and painful erections should seek immediate medical attention. 5.6 Peripheral Vasculopathy, including Raynaud's Phenomenon CNS stimulants used to treat ADHD, including AZSTARYS, are associated with peripheral vasculopathy, including Raynaud's phenomenon. Signs and symptoms are usually intermittent and mild; however, sequelae have included digital ulceration and/or soft tissue breakdown. Effects of peripheral vasculopathy, including Raynaud's phenomenon, were observed in post- marketing reports and at the therapeutic dosage of CNS stimulants in all age groups throughout the course of treatment. Signs and symptoms generally improved after dosage reduction or discontinuation of the CNS stimulant. Careful observation for digital changes is necessary during AZSTARYS treatment. Further clinical evaluation (e.g., rheumatology referral) may be appropriate for AZSTARYS-treated patients who develop signs or symptoms of peripheral vasculopathy. 5.7 Long-Term Suppression of Growth in Pediatric Patients AZSTARYS is not approved for use and is not recommended in pediatric patients below 6 years of age [see Use in Specific Populations ( 8.4 )]. CNS stimulants have been associated with weight loss and slowing of growth rate in pediatric patients. In a long-term, open-label safety study with AZSTARYS conducted in pediatric patients 6 to 12 years of age with ADHD, there was a lower than expected increase in height and weight compared to pediatric patients of the same age and sex, on average [see Adverse Reactions ( 6.1 )] . Closely monitor growth (weight and height) in AZSTARYS-treated pediatric patients. Pediatric patients who are not growing or gaining height or weight as expected may need to have their treatment interrupted. 5.8 Acute Angle Closure Glaucoma There have been reports of angle closure glaucoma associated with methylphenidate treatment. Although the mechanism is not clear, AZSTARYS-treated patients considered at risk for acute angle closure glaucoma (e.g., patients with significant hyperopia) should be evaluated by an ophthalmologist. 5.9 Increased Intraocular Pressure and Glaucoma There have been reports of an elevation of intraocular pressure (IOP) associated with methylphenidate treatment [see Adverse Reactions (6.2) ]. Prescribe AZSTARYS to patients with open-angle glaucoma or abnormally increased IOP only if the benefit of treatment is considered to outweigh the risk. Closely monitor AZSTARYS-treated patients with a history of abnormally increased IOP or open angle glaucoma. 5.10 Motor and Verbal Tics, and Worsening of Tourette’s Syndrome CNS stimulants, including methylphenidate, have been associated with the onset or exacerbation of motor and verbal tics. Worsening of Tourette’s syndrome has also been reported [see Adverse Reactions (6.2) ]. Before initiating AZSTARYS, assess the family history and clinically evaluate patients for tics or Tourette’s syndrome. Regularly monitor AZSTARYS-treated patients for the emergence or worsening of tics or Tourette’s syndrome, and discontinue treatment if clinically appropriate.

7 DRUG INTERACTIONS Antihypertensive Drugs: Monitor blood pressure. Adjust dosage of antihypertensive drug as needed. ( 7.1 ) 7.1 Clinically Important Interactions with AZSTARYS Table 1 presents clinically important drug interactions with AZSTARYS. Table 1: Clinically Important Drug Interactions with AZSTARYS Monoamine Oxidase Inhibitors (MAOIs) Clinical Impact Concomitant use of MAOIs and CNS stimulants, including AZSTARYS, can cause hypertensive crisis. Potential outcomes include death, stroke, myocardial infarction, aortic dissection, ophthalmological complications, eclampsia, pulmonary edema, and renal failure [see Contraindications ( 4 )] . Intervention Do not administer AZSTARYS concomitantly with MAOIs or within 14 days after discontinuing MAOI treatment [see Contraindications ( 4 )] Antihypertensive Drugs Clinical Impact AZSTARYS may decrease the effectiveness of drugs used to treat hypertension [see Warnings and Precautions ( 5.3 )] . Intervention Monitor blood pressure and adjust the dosage of the antihypertensive drug, as needed. Halogenated Anesthetics Clinical Impact Concomitant use of halogenated anesthetics and AZSTARYS may increase the risk of sudden blood pressure and heart rate increase during surgery. Intervention Avoid use of AZSTARYS in patients being treated with anesthetics on the day of surgery. Risperidone Clinical Impact Combined use of methylphenidate with risperidone when there is a change, whether an increase or decrease, in dosage of either or both medications, may increase the risk of extrapyramidal symptoms (EPS). Intervention Monitor for signs of EPS.

6 ADVERSE REACTIONS The following are discussed in more detail in other sections of the labeling: Abuse, Misuse, and Addiction [see Boxed Warning, Warnings and Precautions (5.1) , and Drug Abuse and Dependence (9.2 , 9.3) ] Known hypersensitivity to methylphenidate or other ingredients of AZSTARYS [see Contraindications (4) ] Hypertensive Crisis with Concomitant Use of Monoamine Oxidase Inhibitors [see Contraindications (4) ] Risks to Patients with Serious Cardiac Disease [see Warnings and Precautions (5.2) ] Increased Blood Pressure and Heart Rate [see Warnings and Precautions (5.3) ] Psychiatric Adverse Reactions [see Warnings and Precautions (5.4) ] Priapism [see Warnings and Precautions (5.5) ] Peripheral Vasculopathy, including Raynaud's Phenomenon [see Warnings and Precautions (5.6) ] Long-Term Suppression of Growth in Pediatric Patients [see Warnings and Precautions (5.7) ] Acute Angle Closure Glaucoma [see Warnings and Precautions (5.8) ] Increased Intraocular Pressure and Glaucoma [see Warnings and Precautions (5.9) ] Motor and Verbal Tics, and Worsening of Tourette’s Syndrome [see Warnings and Precautions (5.10) ] Based on accumulated data from other methylphenidate products, the most common (>5% and twice the rate of placebo) adverse reactions are appetite decreased, insomnia, nausea, vomiting, dyspepsia, abdominal pain, weight decreased, anxiety, dizziness, irritability, affect lability, tachycardia, and blood pressure increased.

Adverse Reactions in Studies with Other Methylphenidate Products in Pediatric Patients and Adults with ADHD Commonly reported (≥ 5% of the methylphenidate group and at least twice the rate of the placebo group) adverse reactions from placebo-controlled trials of methylphenidate products include: decreased appetite, decreased weight, nausea, abdominal pain, dyspepsia, vomiting, insomnia, anxiety, affect lability, irritability, dizziness, increased blood pressure, and tachycardia. Adverse Reactions in Studies with AZSTARYS in Pediatric Patients (6 to 12 years) with ADHD Short-Term Study A short-term study conducted in pediatric patients 6 to 12 years of age with ADHD was comprised of a 3-week, open-label, dose optimization phase in which all patients received AZSTARYS (n=155), followed by a 1-week, double-blind, controlled phase in which patients were randomized to continue AZSTARYS (n=74) or switch to placebo (n=76). Because of the study design, the reported adverse reaction rates cannot be used to predict the rates that may be expected in clinical practice. Long-Term Study A long-term, open-label safety study was conducted in pediatric patients 6 to 12 years of age with ADHD who either completed the short-term study or were de novo patients. This study was comprised of a 3-week dose optimization phase for patients not recently treated with AZSTARYS followed by a 12-month treatment phase for all patients during which 238 patients received open- label AZSTARYS and had evaluable safety data. A total of 154 patients were treated for 12 months. Because of the open-label, uncontrolled design of this study, the reported adverse reaction rates cannot be assessed in terms of a causal relationship to AZSTARYS treatment. To adjust for normal growth, z-scores were derived (measured in standard deviations [SD]); z- scores normalize for the natural growth of children and adolescents by comparisons to age- and sex-matched population standards. A z-score change less than 0.5 SD is considered not clinically significant. In this study, the mean increase in weight from baseline to Month 12 was 3.4 kg among study completers. The mean change in z-score from baseline to Month 12 was -0.20, indicating a lower than expected increase in body weight compared to children of the same age and sex, on average. Most of the weight z-score decline occurred in the first 4 months of treatment. The mean increase in height from baseline to Month 12 was 4.9 cm among completers. Using the same z-score analysis for height, the mean change in z-score from baseline to Month 12 was - 0.21, indicating a lower than expected increase in height compared to pediatric patients of the same age and sex, on average. 6.2 Postmarketing Experience The following adverse reactions have been identified during post approval use of methylphenidate products. Because these reactions are reported voluntarily from a population of uncertain size, it is not possible to reliably estimate their frequency or establish a causal relationship to drug exposure. These adverse reactions are as follows: Blood and Lymphatic System Disorders : pancytopenia, thrombocytopenia, thrombocytopenic purpura Cardiac Disorders : angina pectoris, bradycardia, extrasystole, supraventricular tachycardia, ventricular extrasystole, palpitations, increased heart rate Eye Disorders : diplopia, increased intraocular pressure, mydriasis, visual impairment, blurred vision General Disorders : chest pain, chest discomfort, hyperpyrexia Gastrointestinal Disorders : dry mouth Hepatobiliary disorders : hepatocellular injury, acute hepatic failure Immune System Disorders : hypersensitivity reactions such as angioedema, anaphylactic reactions, auricular swelling, bullous conditions, exfoliative conditions, urticarias, pruritus NEC, rashes, eruptions, and exanthemas NEC Investigations : alkaline phosphatase increased, bilirubin increased, hepatic enzyme increased, platelet count decreased, white blood cell count abnormal Musculoskeletal, Connective Tissue and Bone Disorders : arthralgia, myalgia, muscle twitching, rhabdomyolysis, muscle cramps Nervous System : convulsion, grand mal convulsion, dyskinesia, serotonin syndrome in combination with serotonergic drugs, nervousness, headache, tremor, drowsiness, vertigo, motor and verbal tics Psychiatric Disorders : disorientation, libido changes, hallucination, hallucination auditory, hallucination visual, logorrhea, mania, restlessness, agitation Skin and Subcutaneous Tissue Disorders : alopecia, erythema, hyperhidrosis Urogenital System : priapism Vascular Disorders : Raynaud's phenomenon

8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to ADHD medications, including AZSTARYS, during pregnancy. Healthcare providers are encouraged to register patients by calling the National Pregnancy Registry for Psychostimulants at 1-866-961-2388. Risk Summary There are no available data on AZSTARYS use in pregnant women to evaluate for a drug- associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes; however, AZSTARYS contains dexmethylphenidate and serdexmethylphenidate, a prodrug of dexmethylphenidate. Dexmethylphenidate is the d-threo enantiomer of racemic methylphenidate. Published studies and postmarketing reports on methylphenidate use during pregnancy have not identified a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. There may be risks to the fetus associated with the use of CNS stimulants use during pregnancy ( see Clinical Considerations ). Embryo-fetal development studies in rats showed delayed fetal skeletal ossification at doses up to 3 times the maximum recommended human dose (MRHD) of 40 mg/day dexmethylphenidate hydrochloride given to adults based on plasma levels. A decrease in pup weight in males was observed in a pre- and post-natal development study with oral administration of dexmethylphenidate to rats throughout pregnancy and lactation at doses 3 times the MRHD of 40 mg/day dexmethylphenidate hydrochloride given to adults based on plasma levels ( see Data ). No evidence of developmental effects were found in an embryo-fetal development study with oral administration of serdexmethylphenidate to rabbits during organogenesis at doses up to approximately 49 times the MRHD of 52 mg/day serdexmethylphenidate given to adults based on plasma levels ( see Data ). The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. 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 CNS stimulants, such as AZSTARYS, can cause vasoconstriction and thereby decrease placental perfusion. No fetal and/or neonatal adverse reactions have been reported with the use of therapeutic doses of methylphenidate during pregnancy; however, premature delivery and low birth weight infants have been reported in amphetamine-dependent mothers. Data Animal Data In embryo-fetal development studies conducted in rats and rabbits, dexmethylphenidate hydrochloride was administered orally at doses of up to 20 and 100 mg/kg/day, respectively, during the period of organogenesis. No evidence of malformations was found in either the rat or rabbit study; however, delayed fetal skeletal ossification was observed at the highest dose level in rats. When dexmethylphenidate hydrochloride was administered to rats throughout pregnancy and lactation at doses of up to 20 mg/kg/day, post-weaning body weight gain was decreased in male offspring at the highest dose, but no other effects on postnatal development were observed. At the highest doses tested, plasma levels [area under the curves (AUCs)] of dexmethylphenidate in pregnant rats and rabbits were approximately 3 and 1 times, respectively, those in adults dosed with 40 mg/day dexmethylphenidate hydrochloride. Racemic methylphenidate hydrochloride has been shown to cause malformations (increased incidence of fetal spina bifida) in rabbits when given in doses of 200 mg/kg/day throughout organogenesis. No evidence of developmental effects were found in an embryo-fetal development study with oral administration of serdexmethylphenidate in rabbits during organogenesis at doses of up to 374 mg/kg/day. At the highest dose tested, the plasma level [area under the curve (AUC)] of serdexmethylphenidate in pregnant rabbits was approximately 49 times that in adults dosed with 52 mg/day serdexmethylphenidate.
