Brief summary

To assess the pharmacokinetics of a single dose of Aptensio XR® (methylphenidate hydrochloride extended-release) capsules under fed conditions in male or female children 4 to under 6 years of age with ADHD.

Detailed description

This will be a multi-center, open-label, single-dose, study to assess the pharmacokinetics of Aptensio XR® (methylphenidate hydrochloride extended-release) capsules in male and female children 4 to under 6 years of age with ADHD in fed condition. Screening Procedures: After obtaining written informed consent from parents, subjects will undergo a complete medical and medication history, demographic data (including sex, age, race, ethnicity, body weight (kg), height (cm), Body Mass Index (BMI) (kg/m2), physical examination, vital signs evaluation (sitting blood pressure, pulse rate, respiration rate, temperature and pulse oximetry), resting 12-lead electrocardiogram (ECG), clinical laboratory tests and concomitant medication within 28 days prior to receiving study drug. On Day 1: subjects will receive a single oral dose of Aptensio XR®.

Recruitment details

It was a parallel design study, where subjects were recruited from July 02, 2016 - July 19, 2017. Eligible subjects received one capsule of Methylphenidate HCl ER (10, 15, 20, 30, or 40 mg) on only one of the 3 dosing days depending on number of subjects recruited up each particular dosing day. Only 1 site was able to recruit subjects.
