1 INDICATIONS AND USAGE DYANAVEL XR is indicated for the treatment of Attention Deficit Hyperactivity Disorder (ADHD) in patients 6 years and older [see Clinical Studies (14) ]. Limitations of Use The use of DYANAVEL XR 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 (5.5) , Use in Specific Populations (8.4) ]. DYANAVEL XR is a central nervous system (CNS) stimulant indicated for the treatment of Attention Deficit Hyperactivity Disorder (ADHD) in patients 6 years and older ( 1 ) Limitations of Use The use of DYANAVEL XR 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 ( 5.5 , 8.4 ).

2 DOSAGE AND ADMINISTRATION Recommended starting dosage is 2.5 mg or 5 mg once daily in the morning ( 2.2 ) Dosage may be increased in increments of 2.5 mg to 10 mg per day every 4 to 7 days up to a maximum daily dose of 20 mg ( 2.2 ) May be taken with or without food ( 2.3 ) Extended-release oral suspension: Shake bottle before administering ( 2.3 ) Extended-release tablets: May be chewed or swallowed whole ( 2.3 ) DYANAVEL XR oral suspension can be substituted with DYANAVEL XR tablets on a milligram per milligram basis ( 2.4 ) Do not substitute for other amphetamine products on a milligram-per-milligram basis, because of different amphetamine salt compositions and differing pharmacokinetic profiles ( 2.4 ) 2.1 Pretreatment Screening Prior to treating patients with DYANAVEL XR, 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 DYANAVEL XR [see Warnings and Precautions (5.8) ]. 2.2 Recommended Dosage The recommended starting dosage is 2.5 mg or 5 mg once daily in the morning. The dosage may be increased in increments of 2.5 mg to 10 mg per day every 4 to 7 days based on clinical response. The maximum recommended dosage is 20 mg once daily. 2.3 Administration Information Administer DYANAVEL XR orally once daily in the morning with or without food. DYANAVEL XR Extended-Release Oral Suspension Instruct patients to read the “Instructions for Use” for complete administration instructions. Ensure that the bottle adapter is firmly inserted into the bottle and do not remove once inserted. Shake the bottle of DYANAVEL XR extended-release oral suspension well before every administration. Use with the oral dosing dispenser provided by the pharmacist. DYANAVEL XR Extended-Release Tablets May be chewed or swallowed whole [see Clinical Pharmacology (12.3) ]. The 5 mg extended-release tablet is functionally scored and may be divided into equal halves (2.5 mg) at the score line. 2.4 Switching from Other Amphetamine Products DYANAVEL XR extended-release oral suspension can be substituted with DYANAVEL XR extended-release tablets on a milligram-per-milligram basis [ see Clinical Pharmacology (12.3) ] . If switching from other amphetamine products, discontinue that treatment, and titrate with DYANAVEL XR using the above titration schedule. Do not substitute for other amphetamine products on a milligram-per-milligram basis, because of different amphetamine salt compositions and differing pharmacokinetic profiles [ see Description (11) , Clinical Pharmacology (12.3) ] . 2.5 Dosage Modifications due to Drug Interactions Agents that alter urinary pH can impact urinary excretion and alter blood levels of amphetamine. Acidifying agents (e.g., ascorbic acid) decrease blood levels, while alkalinizing agents (e.g., sodium bicarbonate) increase blood levels. Adjust DYANAVEL XR dosage accordingly [ see Drug Interactions (7.1) ] .

4 CONTRAINDICATIONS DYANAVEL XR is contraindicated: In patients known to be hypersensitive to amphetamine, or other components of DYANAVEL XR. Hypersensitivity reactions such as angioedema and anaphylactic reactions have been reported in patients treated with other amphetamine products [ see Adverse Reactions (6) ] . Patients taking monoamine oxidase inhibitors (MAOIs), or within 14 days of stopping MAOIs (including MAOIs such as linezolid or intravenous methylene blue), because of an increased risk of hypertensive crisis [ see Warnings and Precautions (5.7) , Drug Interactions (7.1) ]. Known hypersensitivity to amphetamine products or other ingredients in DYANAVEL XR ( 4 ) Use of monoamine oxidase inhibitor (MAOI) or within 14 days of the last MAOI dose ( 4 , 7.1 )

5 WARNINGS AND PRECAUTIONS Risks to Patients with Serious Cardiac Disease: Avoid use in patients with known structural cardiac abnormalities, cardiomyopathy, serious cardiac arrhythmia, 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 DYANAVEL XR, screen patients for risk factors for developing a manic episode. If new psychotic or manic symptoms occur, consider discontinuing DYANAVEL XR ( 5.4 ) Long-Term Suppression of Growth in Pediatric Patients: Closely monitor growth (height and weight) in pediatric patients. Pediatric patients not growing or gaining height or weight as expected may need to have their treatment interrupted ( 5.5 ) Peripheral Vasculopathy, including Raynaud’s phenomenon: Careful observation for digital changes is necessary during DYANAVEL XR treatment. Further clinical evaluation (e.g., rheumatology referral) may be appropriate for patients who develop signs or symptoms of peripheral vasculopathy ( 5.6 ) Serotonin Syndrome: Increased risk when co-administered with serotonergic agents (e.g., SSRIs, SNRIs, triptans), but also during overdosage situations. If it occurs, discontinue DYANAVEL XR and initiate supportive treatment ( 5.7 ). Motor and Verbal Tics, and Worsening of Tourette’s Syndrome: Before initiating DYANAVEL XR, 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. ( 5.8 ) 5.1 Abuse, Misuse, and Addiction DYANAVEL XR has a high potential for abuse and misuse. The use of DYANAVEL XR exposes individuals to the risks of abuse and misuse, which can lead to the development of a substance use disorder, including addiction. DYANAVEL XR 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 DYANAVEL XR, can result in overdose and death [see Overdosage (10) ] , and this risk is increased with higher doses and or unapproved methods of administration, such as snorting or injection. Before prescribing DYANAVEL XR, 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 DYANAVEL XR in a safe place, preferably locked, and instruct patients to not give DYANAVEL XR to anyone else. Throughout DYANAVEL XR 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 for 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 dosages. Avoid DYANAVEL XR 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 about 2 to 4 mm Hg) and heart rate (mean increase about 3 to 6 bpm). Monitor all DYANAVEL XR-treated patients for potential tachycardia and hypertension.

ronary 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 about 2 to 4 mm Hg) and heart rate (mean increase about 3 to 6 bpm). Monitor all DYANAVEL XR-treated patients for potential tachycardia and hypertension. 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 Disease CNS stimulants may induce a manic or mixed episode in patients with bipolar disorder. Prior to initiating DYANAVEL XR 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 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 DYANAVEL XR. 5.5 Long-Term Suppression of Growth in Pediatric Patients DYANAVEL XR 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. Closely monitor growth (weight and height) in DYANAVEL XR-treated pediatric patients treated with CNS stimulants. Pediatric patients who are not growing or gaining height or weight as expected may need to have their treatment interrupted. 5.6 Peripheral Vasculopathy, including Raynaud's Phenomenon CNS stimulants, including DYANAVEL XR, used to treat ADHD 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 DYANAVEL XR treatment. Further clinical evaluation (e.g., rheumatology referral) may be appropriate for DYANAVEL XR-treated patients who develop signs or symptoms of peripheral vasculopathy. 5.7 Serotonin Syndrome Serotonin syndrome, a potentially life-threatening reaction, may occur when amphetamines are used in combination with other drugs that affect the serotonergic neurotransmitter systems such as monoamine oxidase inhibitors (MAOIs), selective serotonin reuptake inhibitors (SSRIs), serotonin norepinephrine reuptake inhibitors (SNRIs), triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, and St. John’s Wort [ see Drug Interactions (7.1) ] . The co-administration with cytochrome P450 2D6 (CYP2D6) inhibitors may also increase the risk with increased exposure to DYANAVEL XR. In these situations, consider an alternative non-serotonergic drug or an alternative drug that does not inhibit CYP2D6 [ see Drug Interactions (7.1) ] .

[ see Drug Interactions (7.1) ] . The co-administration with cytochrome P450 2D6 (CYP2D6) inhibitors may also increase the risk with increased exposure to DYANAVEL XR. In these situations, consider an alternative non-serotonergic drug or an alternative drug that does not inhibit CYP2D6 [ see Drug Interactions (7.1) ] . Serotonin syndrome symptoms may include mental status changes (e.g., agitation, hallucinations, delirium, and coma), autonomic instability (e.g., tachycardia, labile blood pressure, dizziness, diaphoresis, flushing, hyperthermia), neuromuscular symptoms (e.g., tremor, rigidity, myoclonus, hyperreflexia, incoordination), seizures, and/or gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea). Concomitant use of DYANAVEL XR with MAOI drugs is contraindicated [ see Contraindications (4) ] . Discontinue treatment with DYANAVEL XR and any concomitant serotonergic agents immediately if symptoms of serotonin syndrome occur, and initiate supportive symptomatic treatment. If concomitant use of DYANAVEL XR with other serotonergic drugs or CYP2D6 inhibitors is clinically warranted, initiate DYANAVEL XR with lower doses, monitor patients for the emergence of serotonin syndrome during drug initiation or titration, and inform patients of the increased risk for serotonin syndrome. 5.8 Motor and Verbal Tics, and Worsening of Tourette’s Syndrome CNS stimulants, including amphetamine, 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 DYANAVEL XR, assess the family history and clinically evaluate patients for tics or Tourette’s syndrome. Regularly monitor DYANAVEL XR-treated patients for the emergence or worsening of tics or Tourette’s syndrome, and discontinue treatment if clinically appropriate.

6 ADVERSE REACTIONS The following adverse reactions are discussed in greater 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 ) ] Hypersensitivity to amphetamine, or other components of DYANAVEL XR [see Contraindications (4) ] Hypertensive Crisis When Used Concomitantly with Monoamine Oxidase Inhibitors [see Contraindications (4) and Drug Interactions (7.1) ] 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) ] Long-Term Suppression of Growth in Pediatric Patients [see Warnings and Precautions (5.5) ] Peripheral Vasculopathy, including Raynaud's phenomenon [see Warnings and Precautions (5.6) ] Serotonin Syndrome [see Warnings and Precautions (5.7) ] Motor and Verbal Tics, and Worsening of Tourette’s Syndrome [see Warnings and Precautions (5.8) ] Most common adverse reactions observed with amphetamine products: dry mouth, anorexia, weight loss, abdominal pain, nausea, insomnia, restlessness, emotional lability, dizziness, tachycardia ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Tris Pharma, Inc. at 1-732-940-0358 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. Adverse Reactions in Studies with Other Amphetamine Products in Pediatric Patients and Adults with ADHD Cardiovascular: Palpitations, tachycardia, elevation of blood pressure, sudden death, myocardial infarction. There have been isolated reports of cardiomyopathy associated with chronic amphetamine use. Central Nervous System: Psychotic episodes at recommended doses, overstimulation, restlessness, irritability, euphoria, dyskinesia, dysphoria, depression, tremor, tics, aggression, anger, logorrhea. Eye Disorders: Vision blurred, mydriasis. Gastrointestinal: Dryness of the mouth, unpleasant taste, diarrhea, constipation, other gastrointestinal disturbances. Anorexia and weight loss may occur as undesirable effects. Allergic: Urticaria, rash, hypersensitivity reactions including angioedema and anaphylaxis. Serious skin rashes, including Stevens-Johnson syndrome and toxic epidermal necrolysis have been reported. Endocrine: Impotence, changes in libido. Skin: Alopecia. Adverse Reactions in Studies with DYANAVEL XR in Pediatric Patients with ADHD There is limited experience with DYANAVEL XR in controlled trials. Based on this limited experience, the adverse reaction profile of DYANAVEL XR appears similar to other amphetamine extended-release products. The most common (≥2% in the DYANAVEL XR group and greater than placebo) adverse reactions reported in the Phase 3 controlled study conducted with DYANAVEL XR extended-release oral suspension in 108 patients with ADHD (aged 6 to 12 years) were: epistaxis, allergic rhinitis, and upper abdominal pain. Table 1. Common Adverse Reactions Occurring in ≥2% of Patients on DYANAVEL XR Extended-Release Oral Suspension and Greater than Placebo During the Double Blind Phase.

7 DRUG INTERACTIONS Acidifying and Alkalinizing Agents: Agents that alter urinary pH can alter blood levels of amphetamine. Acidifying agents can decrease amphetamine blood levels, while alkalinizing agents can increase amphetamine blood levels. Adjust DYANAVEL XR dosage accordingly ( 2.5 , 7.1 ) 7.1 Drugs Having Clinically Important Interactions with Amphetamines Table 2. Drugs having clinically important interactions with amphetamines. MAO Inhibitors (MAOI) Clinical Impact MAOI antidepressants slow amphetamine metabolism, increasing amphetamines effect on the release of norepinephrine and other monoamines from adrenergic nerve endings causing headaches and other signs of hypertensive crisis. Toxic neurological effects and malignant hyperpyrexia can occur, sometimes with fatal results. Intervention Do not administer DYANAVEL XR concomitantly or within 14 days following administration of MAOI [ see Contraindications (4) and Warnings and Precautions (5.7) ] . Serotonergic Drugs Clinical Impact The concomitant use of DYANAVEL XR and serotonergic drugs increases the risk of serotonin syndrome. Intervention Initiate with lower doses and monitor patients for signs and symptoms of serotonin syndrome, particularly during DYANAVEL XR initiation or dosage increase. If serotonin syndrome occurs, discontinue DYANAVEL XR and the concomitant serotonergic drug(s) [ see Warnings and Precautions ( 5.7 ) ] . CYP2D6 Inhibitors Clinical Impact The concomitant use of DYANAVEL XR and CYP2D6 inhibitors may increase the exposure of DYANAVEL XR compared to the use of the drug alone and increase the risk of serotonin syndrome. Intervention Initiate with lower doses and monitor patients for signs and symptoms of serotonin syndrome particularly during DYANAVEL XR initiation and after a dosage increase. If serotonin syndrome occurs, discontinue DYANAVEL XR and the CYP2D6 inhibitor [ see Warnings and Precautions (5.7) , Overdosage (10) ] . Alkalinizing Agents (Urinary and Gastrointestinal) Clinical Impact Increase blood levels and potentiate the action of amphetamine. Intervention Co-administration of DYANAVEL XR and gastrointestinal or urinary alkalinizing agents should be avoided. Acidifying Agents (Urinary and Gastrointestinal) Clinical Impact Lower blood levels and efficacy of amphetamines. Intervention Increase dose based on clinical response. Tricyclic Antidepressants Clinical Impact May enhance the activity of tricyclic or sympathomimetic agents causing striking and sustained increases in the concentration of d- amphetamine in the brain; cardiovascular effects can be potentiated. Intervention Monitor frequently and adjust or use alternative therapy based on clinical response. 7.2 Drug/Laboratory Test Interactions Amphetamines can cause a significant elevation in plasma corticosteroid levels. This increase is greatest in the evening. Amphetamines may interfere with urinary steroid determinations.

7.2 Drug/Laboratory Test Interactions Amphetamines can cause a significant elevation in plasma corticosteroid levels. This increase is greatest in the evening. Amphetamines may interfere with urinary steroid determinations.

8 USE IN SPECIFIC POPULATIONS Pregnancy: May cause fetal harm ( 8.1 ) Lactation: Breastfeeding not recommended ( 8.2 ) 8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to DYANAVEL XR during pregnancy. Healthcare providers are encouraged to register patients by calling the National Pregnancy Registry for Psychostimulants at 1-866-961-2388 or visiting online at https://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/othermedications/. Risk Summary There are limited published data on the use of amphetamines in pregnant women. These data are insufficient to determine a drug-associated risk of major congenital malformations or miscarriage. Adverse pregnancy outcomes, including premature delivery and low birth weight, have been seen in infants born to mothers dependent on amphetamines. No effects on morphological development were observed in embryo-fetal development studies with oral administration of amphetamine to rats and rabbits during organogenesis at doses that are approximately 3 and 16 times, respectively, the maximum recommended human dose (MRHD) of 20 mg/day (as base equivalents) on a mg/m 2 basis, given to adults. However, long-term neurochemical and behavioral effects have been reported in published animal developmental studies using clinically relevant doses of amphetamine [see Data ]. 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 Amphetamines, such as DYANAVEL XR, may cause vasoconstriction, including vasoconstriction of placental blood vessels, and may increase the risk for intrauterine growth restriction. In addition, amphetamines can stimulate uterine contractions increasing the risk of premature delivery. Premature delivery and low birth weight infants have been reported in amphetamine-dependent mothers. Monitor infants born to mothers taking amphetamines for symptoms of withdrawal, such as feeding difficulties, irritability, agitation, and excessive drowsiness. Data Animal Data Amphetamine ( d - to l - enantiomer ratio of 3:1) had no apparent effects on embryofetal morphological development or survival when orally administered to pregnant rats and rabbits throughout the period of organogenesis at doses of up to 6 and 16 mg/kg/day, respectively. These doses are approximately 3 and 16 times, respectively, the MRHD of 20 mg/day (as base equivalents) on a mg/m 2 basis, given to adults. Fetal malformations and death have been reported in mice following parenteral administration of d -amphetamine doses of 50 mg/kg/day (approximately 12 times the MRHD) given to adults on a mg/m 2 basis or greater to pregnant animals. Administration of these doses was also associated with severe maternal toxicity. A number of studies in rodents indicate that prenatal or early postnatal exposure to amphetamine ( d - or d , l -), at doses similar to those used clinically, can result in long-term neurochemical and behavioral alterations. Reported behavioral effects include learning and memory deficits, altered locomotor activity, and changes in sexual function.

Reported behavioral effects include learning and memory deficits, altered locomotor activity, and changes in sexual function. 8.2 Lactation Risk Summary Based on limited case reports in published literature, amphetamine ( d - or d , l -) is present in human milk, at relative infant doses of 2% to 13.8% of the maternal weight-adjusted dosage and a milk/plasma ratio ranging between 1.9 and 7.5. There are no reports of adverse effects on the breastfed infant and no effects on milk production. However, long term neurodevelopmental effects on infants from stimulant exposure are unknown. Because of the potential for serious adverse reactions in a breastfed infant, advise patients that breastfeeding is not recommended during treatment with DYANAVEL XR. 8.4 Pediatric Use The safety and effectiveness of DYANAVEL XR have not been established in pediatric patients below the age of 6 years. In studies evaluating extended-release amphetamine products, patients 4 to <6 years of age had higher systemic amphetamine exposures than those observed in older pediatric patients at the same dosage. Pediatric patients 4 to <6 years of age also had a higher incidence of adverse reactions, including weight loss. The safety and effectiveness have been established in pediatric patients with ADHD ages 6 to 17 years [ see Adverse Reactions (6.1) , Clinical Pharmacology (12) , and Clinical Studies (14) ]. Long-Term Growth Suppression Growth should be monitored during treatment with stimulants, including DYANAVEL XR, and pediatric patients who are not growing or gaining weight as expected may need to have their treatment interrupted [ see Warnings and Precautions (5.5) ] . 8.5 Geriatric Use DYANAVEL XR has not been studied in the geriatric population.

8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to DYANAVEL XR during pregnancy. Healthcare providers are encouraged to register patients by calling the National Pregnancy Registry for Psychostimulants at 1-866-961-2388 or visiting online at https://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/othermedications/. Risk Summary There are limited published data on the use of amphetamines in pregnant women. These data are insufficient to determine a drug-associated risk of major congenital malformations or miscarriage. Adverse pregnancy outcomes, including premature delivery and low birth weight, have been seen in infants born to mothers dependent on amphetamines. No effects on morphological development were observed in embryo-fetal development studies with oral administration of amphetamine to rats and rabbits during organogenesis at doses that are approximately 3 and 16 times, respectively, the maximum recommended human dose (MRHD) of 20 mg/day (as base equivalents) on a mg/m 2 basis, given to adults. However, long-term neurochemical and behavioral effects have been reported in published animal developmental studies using clinically relevant doses of amphetamine [see Data ]. 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 Amphetamines, such as DYANAVEL XR, may cause vasoconstriction, including vasoconstriction of placental blood vessels, and may increase the risk for intrauterine growth restriction. In addition, amphetamines can stimulate uterine contractions increasing the risk of premature delivery. Premature delivery and low birth weight infants have been reported in amphetamine-dependent mothers. Monitor infants born to mothers taking amphetamines for symptoms of withdrawal, such as feeding difficulties, irritability, agitation, and excessive drowsiness. Data Animal Data Amphetamine ( d - to l - enantiomer ratio of 3:1) had no apparent effects on embryofetal morphological development or survival when orally administered to pregnant rats and rabbits throughout the period of organogenesis at doses of up to 6 and 16 mg/kg/day, respectively. These doses are approximately 3 and 16 times, respectively, the MRHD of 20 mg/day (as base equivalents) on a mg/m 2 basis, given to adults. Fetal malformations and death have been reported in mice following parenteral administration of d -amphetamine doses of 50 mg/kg/day (approximately 12 times the MRHD) given to adults on a mg/m 2 basis or greater to pregnant animals. Administration of these doses was also associated with severe maternal toxicity. A number of studies in rodents indicate that prenatal or early postnatal exposure to amphetamine ( d - or d , l -), at doses similar to those used clinically, can result in long-term neurochemical and behavioral alterations.

9 DRUG ABUSE AND DEPENDENCE 9.1 Controlled Substance DYANAVEL XR contains amphetamine, a Schedule II controlled substance. 9.2 Abuse DYANAVEL XR has a high potential for abuse and misuse which can lead to the development of a substance use disorder, including addiction [see Warnings and Precautions (5.1) ] . DYANAVEL XR can be diverted for non-medical use into illicit channels or distribution. Abuse is the intentional non-therapeutic use of a drug, even once, to achieve a desired psychological or physiological effect. Misuse is the intentional use, for therapeutic purposes, of a drug by an individual in a way other than prescribed by a health care provider or for whom it was not prescribed. Drug addiction is a cluster of behavioral, cognitive, and physiological phenomena that may include a strong desire to take the drug, difficulties in controlling drug use (e.g., continuing drug use despite harmful consequences, giving a higher priority to drug use than other activities and obligations), and possible tolerance or physical dependence. Misuse and abuse of amphetamine may cause increased heart rate, respiratory rate, or blood pressure; sweating; dilated pupils; hyperactivity; restlessness; insomnia; decreased appetite; loss of coordination; tremors; flushed skin; vomiting; and/or abdominal pain. Anxiety, psychosis, hostility, aggression, and suicidal or homicidal ideation have also been observed with CNS stimulants abuse and/or misuse. Misuse and abuse of CNS stimulants, including DYANAVEL XR, 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. 9.3 Dependence Physical Dependence DYANAVEL XR may produce physical dependence. Physical dependence is a state that develops as a result of physiological adaptation in response to repeated drug use, manifested by withdrawal signs and symptoms after abrupt discontinuation or a significant dose reduction of a drug. Withdrawal signs and symptoms after abrupt discontinuation or dose reduction following prolonged use of CNS stimulants including DYANAVEL XR include dysphoric mood; depression; fatigue; vivid, unpleasant dreams; insomnia or hypersomnia; increased appetite; and psychomotor retardation or agitation. Tolerance DYANAVEL XR may produce tolerance. Tolerance is a physiological state characterized by a reduced response to a drug after repeated administration (i.e., a higher dose of a drug is required to produce the same effect that was once obtained at a lower dose).

10 OVERDOSAGE Clinical Effects of Overdose Overdose of CNS stimulants is characterized by the following sympathomimetic effects: Cardiovascular effects including tachyarrhythmias, and hypertension or hypotension. Vasospasm, myocardial infarction, or aortic dissection may precipitate sudden cardiac death. Takotsubo cardiomyopathy may develop. CNS effects including psychomotor agitation, confusion, and hallucinations. Serotonin syndrome, seizures, cerebral vascular accidents, and coma may occur. Life-threatening hyperthermia (temperatures greater than 104°F) and rhabdomyolysis may develop. Overdose Management Consider the possibility of multiple drug ingestion. The pharmacokinetic profile of DYANAVEL XR should be considered when treating patients with overdose. D-amphetamine is not dialyzable. Consider contacting the Poison Help line (1-800-222-1222) or a medical toxicologist for additional overdose management recommendations.

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Amphetamines are non-catecholamine sympathomimetic amines with CNS stimulant activity. The mode of therapeutic action in ADHD is not known. 12.2 Pharmacodynamics Amphetamines block the reuptake of norepinephrine and dopamine into the presynaptic neuron and increase the release of these monoamines into the extra neuronal space. 12.3 Pharmacokinetics Absorption Extended-Release Oral Suspension Following a single 18.8 mg dose of DYANAVEL XR extended-release oral suspension in 29 healthy adult subjects under fasting conditions in a crossover study, the median (range) time to peak plasma concentrations (T max ) for both d- and l- isomers of amphetamine were 4 (2 to 7) hours after dosing. Peak concentrations (C max ) of d- and l- amphetamine were 102% and 106%, respectively, of the C max of immediate-release (IR) mixed amphetamine salts (MAS) tablets. The relative bioavailability of DYANAVEL XR compared with an equal dose of IR MAS tablets is 106% for d - and 111% for l -amphetamine. Following a single 18.8 mg dose of DYANAVEL XR extended-release oral suspension in 28 healthy adult subjects in a crossover study under fasting conditions, the median (range) time to peak plasma concentrations (T max ) were about 4 (2 to 7) hours and 5 (3 to 7) hours for d - and l -amphetamine, respectively. Peak concentration (C max ) was 93% and 94%, respectively, of the C max of extended release (ER) MAS capsules. The relative bioavailability of DYANAVEL XR compared with an equal dose of ER MAS capsules is 94% for both d - and l -amphetamine. Figure 1. Mean d - and l -Amphetamine Plasma Concentration-Time Profile Following Administration of a Single Dose (18.8 mg amphetamine base) of DYANAVEL XR Extended-Release Oral Suspension and MAS ER Under Fasting Conditions Extended-Release Tablet Following a single 20 mg dose of DYANAVEL XR extended-release tablets (swallowed whole) to 36 healthy adults under fasted conditions in a crossover study, the median (range) time to peak plasma concentration (T max ) for both d - and l -amphetamine, were 5.0 (2 to 9) hours after dosing. Peak concentrations (C max ) for both d - and l -amphetamine, were 101% of the C max of DYANAVEL XR oral suspension. The relative bioavailability of DYANAVEL XR tablets compared with an equal dose of DYANAVEL XR oral suspension, for d - and l -amphetamine, were 105% and 106%, respectively. Dyanavel XR extended-release tablets chewed or swallowed whole under fasted conditions did not significantly affect exposure and T max. Figure 2. Mean Plasma d - and l- Amphetamine Concentration-Time Profiles for DYANAVEL XR Extended-Release Tablet and DYANAVEL XR Extended-Release Oral Suspension Effect of Food Extended-Release Oral Suspension Ingestion of 18.8 mg of DYANAVEL XR extended-release oral suspension with a high-fat meal increased the average C max of both isomers of DYANAVEL XR by about 2%, decreased the AUC of d- and l- amphetamine by 5.7% and 7.4%, respectively. A delay of T max by approximately 1 hour was observed for both isomers. Extended-Release Tablet Ingestion of 20 mg DYANAVEL XR extended-release tablets with a high-fat meal decreased the average C max of both isomers of amphetamine by about 3%, decreased AUC of d - and l -amphetamine by about 4.0% and 7.3%, respectively. Median T max was not delayed for either isomer.

Extended-Release Tablet Ingestion of 20 mg DYANAVEL XR extended-release tablets with a high-fat meal decreased the average C max of both isomers of amphetamine by about 3%, decreased AUC of d - and l -amphetamine by about 4.0% and 7.3%, respectively. Median T max was not delayed for either isomer. Elimination The mean plasma terminal elimination half-lives of d - and l- amphetamine were 12.4 hours and 15.1 hours, respectively, following a single 18.8 mg dose of DYANAVEL XR extended-release oral suspension. The mean plasma terminal elimination half-lives of d- and l- amphetamine were 13.5 hours and 17.3 hours, respectively, following a single 20 mg dose of DYANAVEL XR extended-release tablets. Metabolism Amphetamine is reported to be oxidized at the 4 position of the benzene ring to form 4‑hydroxyamphetamine, or on the side chain A or B carbons to form alpha-hydroxy-amphetamine or norephedrine, respectively. Norephedrine and 4-hydroxy-amphetamine are both active and each is subsequently oxidized to form 4-hydroxy-norephedrine. Alpha-hydroxy-amphetamine undergoes deamination to form phenylacetone, which ultimately forms benzoic acid and its glucuronide and the glycine conjugate hippuric acid. Although the enzymes involved in amphetamine metabolism have not been clearly defined, CYP2D6 is known to be involved with formation of 4-hydroxy-amphetamine. Because CYP2D6 is genetically polymorphic, population variations in amphetamine metabolism are a possibility. Excretion With normal urine pH, approximately half of an administered dose of amphetamine is recoverable in urine as derivatives of alpha-hydroxy-amphetamine and approximately another 30%-40% of the dose is recoverable in urine as amphetamine itself. Specific Populations Pediatric Patients Following a single 10 mg dose of DYANAVEL XR extended-release oral suspension in pediatric subjects with ADHD (aged 6 to 12 years) under fasting conditions, peak plasma concentrations of d -and l -amphetamine occurred at a median time of 3.9 and 4.5 hours after dosing, respectively. The mean plasma terminal elimination half-lives of d - and l- amphetamine were 10.4 hours and 12.1 hours, respectively. Patients with Hepatic or Renal Impairment No specific studies have been conducted to evaluate the effect of renal impairment or hepatic impairment on the PK after DYANAVEL XR administration. However, urinary recovery of amphetamine has been reported to range from 1% to 75%, depending on urinary pH, with the remaining fraction of the dose hepatically metabolized. Consequently, both hepatic and renal dysfunctions have the potential to inhibit the elimination of amphetamine and result in prolonged exposures. Drug Interaction Studies CYP Enzymes In vitro experiments with human microsomes indicate minor inhibition of CYP2D6 by amphetamine and minor inhibition of CYP1A2, 2D6, and 3A4 by one or more metabolites. However, because of the probability of auto-inhibition and the lack of information on the concentration of these metabolites relative to in vivo concentrations, no predications regarding the potential for amphetamine or its metabolites to inhibit the metabolism of other drugs by CYP isozymes in vivo can be made. Urine pH Modulators Because amphetamine has a pKa of 9.9, urinary recovery of amphetamine is highly dependent on pH and urine flow rates. Alkaline urine pH results in less ionization and reduced renal elimination; acidic pH and high flow rates result in increased renal elimination with clearances greater than glomerular filtration rates, indicating the involvement of active secretion.

ecovery of amphetamine is highly dependent on pH and urine flow rates. Alkaline urine pH results in less ionization and reduced renal elimination; acidic pH and high flow rates result in increased renal elimination with clearances greater than glomerular filtration rates, indicating the involvement of active secretion. In addition, any decrease in amphetamine’s metabolism that might occur due to drug interactions or genetic polymorphisms is more likely to be clinically significant when renal elimination is decreased [ see Drug Interactions ( 7.1 ) ] . Alcohol Effect There is no in vivo study conducted for the effect of alcohol on drug exposure. An in vitro dissolution study on DYANAVEL XR extended-release oral suspension showed alcohol-induced dose dumping potential in the presence of 40% alcohol. A similar study on the DYANAVEL XR extended-release tablets showed no alcohol-induced dose dumping in the presence of 40% alcohol. Dose dumping was not observed in the presence of 5%, 10%, or 20% alcohol concentrations for either product. Figure1 Figure2

13 NONCLINICAL TOXICOLOGY 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis No evidence of carcinogenicity was found in studies in which d, l -amphetamine (enantiomer ratio of 1:1) was administered to mice and rats in the diet for 2 years at doses of up to 30 mg/kg/day in male mice, 19 mg/kg/day in female mice, and 5 mg/kg/day in male and female rats. These doses are approximately 7, 5, and 2 times, respectively, the maximum recommended human dose of 20- mg/day (as base equivalents) given to adults, on a mg/m 2 basis. Mutagenesis Amphetamine, in the enantiomer ratio ( d - to l - ratio of approximately 3:1), was not clastogenic in the mouse bone marrow micronucleus test in vivo and was negative when tested in the E. coli component of the Ames test in vitro . d , l -Amphetamine (1:1 enantiomer ratio) has been reported to produce a positive response in the mouse bone marrow micronucleus test, an equivocal response in the Ames test, and negative responses in the in vitro sister chromatid exchange and chromosomal aberration assays. Impairment of Fertility Amphetamine, in the enantiomer ratio ( d - to l - ratio of approximately 3:1), did not adversely affect fertility or early embryonic development in the rat at doses of up to 20 mg/kg/day [ approximately 10 times the maximum recommended human dose of 20 mg/day (as base equivalents) given to adults on a mg/m 2 basis ] . 13.2 Animal Toxicology and/or Pharmacology Acute administration of high doses of amphetamine ( d - or d , l -) has been shown to produce long-lasting neurotoxic effects, including irreversible nerve fiber damage, in rodents. The significance of these findings to humans is unknown.

14 CLINICAL STUDIES The efficacy of DYANAVEL XR extended-release oral suspension was evaluated in a laboratory classroom study conducted in 108 pediatric patients (aged 6 to 12 years) with ADHD. The study began with an open-label dose optimization period (5 weeks) with an initial DYANAVEL XR dose of 2.5 or 5 mg once daily in the morning. The dose could be titrated weekly in increments of 2.5 to 10 mg until an optimal dose or the maximum dose of 20 mg/day was reached. Subjects then entered a 1-week randomized, double-blind treatment with the individually optimized dose of DYANAVEL XR or placebo. At the end of the week, school teachers and raters evaluated the attention and behavior of the subjects in a laboratory classroom using the Swanson, Kotkin, Agler, M-Flynn, and Pelham (SKAMP) rating scale. SKAMP is a 13-item teacher-rated scale that assesses manifestations of ADHD in a classroom setting. Each item is rated on a 7-point impairment scale. The primary efficacy endpoint was change from pre-dose in the SKAMP-Combined score at 4 hours post-dosing. The key secondary efficacy parameters were onset and duration of clinical effect. The change scores from pre-dose SKAMP-Combined scores at post-dose time points (1, 2, 4, 6, 8, 10, 12 and 13 hours) were used to evaluate the key secondary efficacy parameters. Results from the double-blind, placebo-controlled week of the study are summarized in Table 3 and Figure 3. SKAMP-Combined change scores from pre-dose demonstrated a statistically significant improvement at all time points (1, 2, 4, 6, 8, 10, 12, 13 hours) post-dosing with DYANAVEL XR compared to placebo.
