Brief Summary
The 5-milligram (mg) dose of prasugrel in low body weight (LBW) patients with coronary artery disease produces a pharmacodynamic response within the same therapeutic range as 10-mg dose in higher body weight (HBW) patients.

Outcome Measures
Primary Outcomes (1)
Change From Baseline in Maximum Platelet Aggregation (MPA) to 20 Micromolar (µM) Adenosine Diphosphate (ADP) at Day 12 (Period 1)
MPA to 20 micromolar (μM) ADP was assessed by light transmission aggregometry (LTA), an assay that measures platelet aggregation by determining the amount of light transmitted through a cuvette containing platelet-rich plasma stimulated with a platelet activator, such as ADP, relative to platelet-poor plasma (100% light transmittance). A lower MPA reflects stronger platelet inhibition, whereas a higher MPA reflects weaker inhibition.
Baseline, Day 12
Secondary Outcomes (4)
Change From Baseline in Vasodilator-Associated Stimulated Phosphoprotein (VASP) at Day 12 of Therapy
Baseline, Day 12
Change From Baseline in VerifyNow® P2Y12 Reaction Units (PRU) at Day 12 of Therapy
Baseline, Day 12
Pharmacokinetic (PK) Analysis of the Concentration-Time Curve (AUC)

Eligibility Criteria
You may qualify if:
- Subjects with a history of stable coronary artery disease who are not currently indicated for treatment with a thienopyridine (that is, prasugrel, clopidogrel, or ticlopidine)
- Provision of written informed consent
- For women of child-bearing potential only (that is, women who are not surgically or chemically sterilised and who are between menarche and 1 year post menopause), test negative for pregnancy (based on a urine or serum pregnancy test to be performed before randomisation) and agree to use a reliable method of birth control during the study
You may not qualify if:
- Unstable coronary artery disease
- Percutaneous Coronary Intervention (PCI) or Coronary Artery Bypass Graft Surgery (CABG) within the previous 90 days
- History of refractory ventricular arrhythmias within the last 6 months; an implanted defibrillator device; congestive heart failure within 6 months prior to screening; major surgery, or severe trauma, fracture or organ biopsy within 3 months prior to enrollment
- Any planned surgical procedure or any coronary revascularisation (surgical or percutaneous) planned within 60 days following randomisation
- Any known contraindication to treatment with an antiplatelet agent
- Significant hypertension at the time of screening or randomisation
- Clinically significant out-of-range values for platelet count or haemoglobin at screening, in the investigator's opinion, or results of clinical laboratory tests at the time of screening that are judged to be clinically significant for the study population, as determined by the investigator
- Prior history or presence of significant bleeding disorders, abnormal bleeding tendency, or personal history of coagulation or bleeding disorders.
- Prior history or clinical suspicion of cerebral vascular malformations, intracranial neoplasm, Transient Ischemic Attack (TIA) or stroke.
- Prior history of thrombocytopenia or thrombocytosis
- Use of antiplatelet agents (besides aspirin) within 10 days prior to screening; the use (or planned use) of heparin, oral anticoagulants, or fibrinolytic agents within 30 days of screening; or subjects receiving daily treatment with nonsteroidal anti-inflammatory drugs (NSAIDS) or cyclooxygenase-2 (COX-2) inhibitors that cannot be discontinued for the duration of the study
