Loading your page…

Indications

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 ).

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 )

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.

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 )

7.1Drugs 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.

7.2Drug/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.

8.1Pregnancy 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.

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 .

6.1Clinical 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. Preferred Term DYANAVEL XR (N=52) Placebo (N=48) Respiratory, thoracic and mediastinal disorders Epistaxis 3.8% 0% Rhinitis allergic 3.8% 0% Gastrointestinal disorders Abdominal pain upper 3.8% 2.1%

6.2Postmarketing Experience

The following adverse reactions have been identified during post approval use of other amphetamine 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. Allergic : urticaria, rash, hypersensitivity reactions including angioedema and anaphylaxis. Serious skin rashes, including Stevens-Johnson Syndrome and toxic epidermal necrolysis have been reported Cardiovascular : palpitations, sudden death, myocardial infarction.

There have been isolated reports of cardiomyopathy associated with chronic amphetamine use Central Nervous System : restlessness, irritability, euphoria, dyskinesia, dysphoria, depression, tremor, aggression, anger, logorrhea, and paresthesia (including formication), motor and verbal tics Endocrine : impotence, changes in libido, frequent or prolonged erections Eye Disorders : vision blurred, mydriasis Gastrointestinal : unpleasant taste, constipation, intestinal ischemia, and other gastrointestinal disturbances Musculoskeletal, Connective Tissue, and Bone Disorders : rhabdomyolysis Psychiatric Disorders : dermatillomania, bruxism Skin : alopecia Vascular Disorders : Raynaud’s phenomenon
