About

The objective of this study was to evaluate the plasma amphetamine concentration/time profile of amphetamine extended release oral suspension in children aged 4 to 5 years with attention-deficit/hyperactivity disorder, following a single 2.5 mg dose of amphetamine extended release oral suspension.

Full description

DYANAVEL® XR is an extended-release oral suspension that contains 2.5 mg/mL amphetamine base (amphetamine extended-release oral suspension; AMPH EROS). Drug-resin complexation is formed with the amphetamine and sodium polystyrene sulfonate, an ion exchange resin. The extended release feature of the product is achieved by coating a portion of the drug/resin complexes with an extended release coating. AMPH EROS contains approximately a 3.2:1 ratio of d-amphetamine compared to l-amphetamine. The objective of this study was to evaluate the plasma amphetamine concentration/time profile of AMPH EROS in children aged 4 to 5 years with attention-deficit/hyperactivity disorder, following a single 2.5 mg dose of AMPH EROS. These data will guide appropriate dosing in planned safety and efficacy studies with AMPH EROS in a preschool population with attention-deficit/hyperactivity disorder.

Inclusion criteria

  • Male or female aged 4 to 5 years at the time of enrollment into this study;
  • Body weight ≥ 28 lb. at screening visit;
  • Diagnosed with ADHD by a psychiatrist, psychologist, developmental pediatrician, pediatrician, or an experienced licensed allied health professional approved by the Sponsor by using the DSM-5 criteria and supported by a structured Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime version (K-SADS-PL) interview, administered at the Screening Visit (Visit 0);
  • Provide written informed consent (parent/guardian) prior to participation in the study.

Exclusion criteria

  • Diagnosed with any DSM-5 active disorder (other than ADHD) with the exception of specific phobias, learning disorders, motor skills disorders, communication disorders,oppositional defiant disorder, elimination disorders, and sleep disorders
  • History of chronic medical illnesses including seizure disorder (excluding a history of febrile seizures), moderate to severe hypertension, untreated thyroid disease, known structural cardiac disorders, serious cardiac conditions, serious arrhythmias, cardiomyopathy and known family history of sudden death
  • Known history or presence of significant renal or hepatic disease, as indicated by clinical laboratory assessment (liver function test results ≥ 2 times the upper limit of normal, blood urea nitrogen, or creatinine)
  • Clinically significant (CS) abnormal ECG or cardiac findings on physical examination (including the presence of a pathologic murmur)

Use of the following medications within 30 days of dosing:

  • MAOI - monoamine oxidase inhibitors (e.g., Selegiline, isocarboxazid, phenelzine, tranylcypromine);
  • Tricyclic Antidepressants (e.g. Desipramine, protriptyline);

Use of the following medications within 3 days of dosing

  • Gastrointestinal acidifying agents (e.g., guanethidine, reserpine, glutamic acid HCl, ascorbic acid);
  • Urinary acidifying agents (e.g., ammonium chloride, sodium acid phosphate,methenamine salts);
  • Use of atomoxetine within 14 days of dosing
  • Planned use of prohibited drugs or agents from the screening visit through the end of the study. Medications used to support sleep may be acceptable with the written approval of the sponsor or medical monitor
  • Abnormal CS laboratory test value at screening that, in the opinion of the sponsor or medical monitor, would preclude study participation
  • Known history of allergy/hypersensitivity to amphetamine or any of the components of AMPH EROS, heparin flush and topical anesthetics
  • Parent or guardian's inability or unwillingness to follow directions of the Investigator or study research staff
  • Any uncontrolled medical condition that in the opinion of the Investigator would preclude study participation
  • History of significant illness requiring hospitalization, or surgery requiring anesthetics within 30 days of dosing.
