Exclusion

  • Medical History
  • Current and/or recurrent disease or illness that, in the opinion of an investigator, could affect the study conduct, study outcome, subject safety, or pharmacokinetic (PK) assessments (e.g., hepatic disorders, renal insufficiency, non-self-limiting gastrointestinal disorders, congestive heart failure).
  • Current and/or previous history of any other serious, severe or unstable psychiatric illness which in the opinion of the investigator, may require treatment (e.g. anxiety, psychosis, mood disorder, motor tics or suicidality) or make the subject unlikely to fully complete the study, and/or any condition that presents undue risk from the study medication or procedures.

  • Subject is breast-feeding during the study or within 30 days of the study.
  • Medications
  • a. Subject has taken any medication that, in the opinion of an Investigator, has been shown to alter the PK of d-MPH.

  • iii. On a case-by-case basis, an Investigator is permitted to allow the use of certain concomitant medications, for example, to treat an AE, as long as an Investigator determines that the medication will not affect the subject's safety or study integrity (eg, topical medications).
  • Alcohol/Substance Abuse
  • Recent history (within the last year) of alcohol or other substance abuse.
  • Subject has positive breath alcohol test or urine test for drugs of abuse at screening or check-in (prescribed ADHD medication is acceptable during screening but must be stopped at least 96 hrs prior to check in at Day -4). Note: At the discretion of an Investigator, the tests may be repeated. If THC is positive at screening or check-in, a cannabis intoxication evaluation will be done by an investigator at check-in only; inclusion will be at the investigator's discretion, due to the slow release of THC from adipose tissue.
