Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Potential participants are pre-screened at the Duke Obesity Clinic. Eligible participants then come to the Duke ADHD Clinic for their first study visit.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
At the screening visit, psychiatric evaluation and fasting labs were obtained to determine eligibility. Of the 14 subjects only 2 qualified and received study drug. Reasons for screen fails: 8-did not meet lab parameters for glucose intolerance, 1-elevated BP, 1- elevated TSH, 1- doing well with current ADHD treatment, 1- diagnosed with depression.

Reporting Groups
Open Label Vyvanse Eligible subjects will be dispensed open label LDX (Vyvanse). All subjects will start at 20 mg once a day dose and will be titrated up weekly by 10 mg increments up to a maximum dose of 70 mg. If a subject experiences intolerable side effects at a particular dose, a step down to the next tolerated level is allowed.

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
Study was terminated due to the high number of failures of lab criteria for glucose intolerance which is one of the entry criterion. No data were analyzed.
