  • Area Under the Steady-state Plasma Concentration-time Curve (AUC 0-t) for Methylphenidate Hydrochloride (MPH) Using Two Different Formulations (Equasym XL and Metadate CD) [ Time Frame: predose and 0.5, 1.0, 1.25, 1.5, 2, 3, 4, 5, 6, 8, 10, 12, 16, 20 and 24 hours post-dose ]
    AUC 0-t is the area under the plasma concentration versus time curve from time 0 to the time of last quantifiable concentration. AUC can be used as a measure of drug exposure. It is derived from drug concentration and time so it gives a measure how much and how long a drug stays in a body.
  • Maximum Plasma Concentration (Cmax) for MPH Using Two Different Formulations (Equasym XL and Metadate CD) [ Time Frame: predose and 0.5, 1.0, 1.25, 1.5, 2, 3, 4, 5, 6, 8, 10, 12, 16, 20 and 24 hours post-dose ]
    Cmax is a term that refers to the maximum (or peak) concentration that a drug achieves in the body after the drug has been administrated.
  • Time of Maximum Plasma Concentration (Tmax) for MPH Using Two Different Formulations (Equasym XL and Metadate CD) [ Time Frame: predose and 0.5, 1.0, 1.25, 1.5, 2, 3, 4, 5, 6, 8, 10, 12, 16, 20 and 24 hours post-dose ]
    Tmax is the time after administration of a drug when the maximum plasma concentration in the body is reached.
To assess bioequivalence of methylphenidate hydrochloride (60 mg capsule) with SPD544 (two 30 mg capsules) following single oral doses. [ Time Frame: predose and 0.5, 1.0, 1.25, 1.5, 2, 3, 4, 5, 6, 8, 10, 12, 16, 20 and 24 hours post-dose ]

SPD544 High Strength Bioequivalence Study
Phase 1,Randomized,Open-Label,Two Period Single Dose Crossover Bioequivalence Study of Two Capsule Strengths of SPD544 In Healthy Volunteers.
The purpose of this study is to assess bioequivalence of 2 capsule strengths.
This will be a randomised, open-label, two-period, single dose, crossover bioequivalence study in healthy subjects under fasting conditions to assess bioequivalence of 1 x 60 mg capsule methylphenidate compared to 2 x 30 mg capsules methylphenidate. Pharmacokinetics and safety will be assessed.

Inclusion criteria:

  1. Healthy subjects, aged 18-55 years inclusive at the time of consent.
  2. Subject must be willing to comply with applicable contraceptive requirements of the protocol and be:

    • Male, or
    • Non-pregnant, non-lactating female who must be >90 days post-partum or nulliparous.
  3. Body Mass Index (BMI) between 18.5 and 30.0kg/m² inclusive. This inclusion criterion will only be assessed at the Screening visit.
  4. Satisfactory medical assessment with no clinically significant or relevant abnormalities in medical history, physical examination, vital signs, ECG, and clinical laboratory evaluation (haematology, biochemistry, urinalysis) as assessed by the Investigator.
  5. Ability to provide written, personally signed and dated informed consent to participate in the study.
  6. An understanding, ability and willingness to fully comply with study procedures and restrictions.
  7. Ability to swallow all investigational medicinal products (IMPs).

Exclusion criteria:

  1. Current or recurrent disease (e.g., cardiovascular, renal, liver, gastrointestinal, malignancy or other conditions) that could affect the action, absorption, or disposition of the IMPs, or could affect clinical or laboratory assessments.
  2. Current or relevant history of physical or psychiatric illness, any medical disorder that may require treatment or make the subject unlikely to fully comply with the requirements of the study or complete the study, or any condition that presents undue risk from the IMPs or study procedures.
  3. Current use of any medication (including prescription, over-the-counter [OTC], herbal, or homeopathic preparations) with the exception of hormone replacement therapy or hormonal contraceptives and/or an occasional dose of nonsteroidal anti-inflammatory (NSAID), or paracetamol (current use is defined as use within 14 days of first dose of IMP).
  4. History of hypertension or a resting sitting systolic blood pressure >139mmHg or diastolic blood pressure >89mmHg.
  5. History of seizure (other than infantile febrile seizures), any tic disorder, or a current diagnosis and/or family history of Tourette's Disorder.
  6. Known history of symptomatic cardiovascular disease, advanced arteriosclerosis, structural cardiac abnormality, cardiomyopathy, serious heart rhythm abnormalities, coronary artery disease, transient ischaemic attack or stroke, or other serious cardiac problems that may place them at increased vulnerability to the sympathomimetic effects of a stimulant drug.
  7. Family history of sudden cardiac death or ventricular arrhythmia.
  8. Known cerebrovascular disorders such as cerebral aneurysm, vascular abnormalities including vasculitis or history of stroke.
  9. Diagnosis of glaucoma.
  10. Diagnosis of phaeochromocytoma.
  11. Current abnormal thyroid function, as defined as abnormal screening thyroid stimulating hormone (TSH) and thyroxine (T4).
  12. Current marked anxiety, tension and/or agitation.

  14. A positive screen for alcohol or drugs of abuse at Screening or Day -1 of Treatment Period 1.
  15. Male subjects who consume more than 3 units of alcohol per day. Female subjects who consume more than 2 units of alcohol per day.
  16. A positive human immunodeficiency virus (HIV) antibody screen, Hepatitis B surface antigen (HBsAg), or Hepatitis C virus (HCV) antibody screen.
  17. Use of tobacco in any form (e.g., smoking or chewing) or other nicotine-containing products in any form (e.g., gum, patch) within 30 days prior to the Screening visit.
