          4. In the clinical judgment of the Investigator, the subject must be in need of
             pharmacological treatment for ADHD.

          5. Females of childbearing potential must be non-lactating and must have a negative serum
             pregnancy test at screening

        Exclusion Criteria:

          1. 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

          2. Known history of chronic medical illnesses including severe hypertension, untreated
             thyroid disease, peripheral vasculopathy, known structural cardiac disorders, serious
             cardiac conditions, serious arrhythmias, cardiomyopathy, known family history of
             sudden death

          3. Known history or presence of significant renal or hepatic disease, as indicated by
             clinical laboratory assessment (liver function test results ≥ two times the upper
             limit of normal, blood urea nitrogen, or creatinine).

          4. Clinically significant abnormal ECG or cardiac findings on physical examination
             (including the presence of a pathologic murmur)

          5. Use of the following medications within 30 days of Baseline Visit:

               -  MAOI - monoamine oxidase inhibitors (e.g., Selegiline, isocarboxazid, phenelzine,

               -  Tricyclic Antidepressants (e.g. Desipramine, protriptyline)

          6. Use of the following medications within 3 days of Baseline Visit

                  HCl, ascorbic acid)

               -  Urinary acidifying agents (e.g., ammonium chloride, sodium acid phosphate,
                  methenamine salts)

          7. Use of atomoxetine within 14 days of Baseline Visit

          8. Planned use of prohibited drugs or agents from the Screening visit through the end of
             the study

          9. Abnormal clinically significantly laboratory test value at screening that, in the
             opinion of the Investigator, would preclude study participation

         10. Known history of allergy/hypersensitivity to amphetamine or any of the components of
             Dyanavel XR, or topical anaesthetics

         11. Known history of lack of response to amphetamine
