Title: A Comparison of CS-747 and Clopidogrel in Acute Coronary Syndrome Subjects Who Are to Undergo Percutaneous Coronary Intervention
Brief Summary: The sponsors of this investigational drug are developing prasugrel (also known as CS-747) as a possible treatment for patients with acute coronary syndrome (heart attack or chest pain) who need, or are expected to need, a percutaneous coronary intervention (PCI; also called a balloon angioplasty). Prasugrel was compared with Clopidogrel to determine which drug is better at reducing deaths, future heart attacks, or stroke.


Options:
A: Inclusion Criteria:

* Women and men 55 years of age or over with established CVD and at high risk for future fatal and nonfatal CV events, defined as:

  1. Documented coronary artery disease (CAD);
  2. Documented peripheral vascular disease (PVD);
  3. Documented cerebrovascular disease;
  4. Diabetes with one of the following; additional cardiovascular risk factors:

  i) hypertension (BP \>160 mmHg systolic or \>90 mmHg diastolic or on treatment); ii) total cholesterol \>5.2 mmol/L (\>200 mg/dl); iii) HDL cholesterol \<0.9 mmol/L (3.5 mg/dl); iv) current cigarette smoker; v) any evidence of previous vascular disease
* Provision of informed consent

Exclusion Criteria:

* Current use of any vitamin supplements containing folic acid \>200 micrograms/day. The patients taking such vitamin supplements can be asked if they agree to discontinue these supplements. If they agree, they can be randomized to the study following a one month wash-out period.
* Known previous adverse reactions to folic acid and/or vitamin B6 and/or B12.
* Planned cardiac, peripheral or cerebrovascular revascularization, defined as a decision taken by the patient and his or her physician(s) to perform surgical or percutaneous transluminal revascularization within the next 6 months.
* Hemodynamically significant primary valvular outflow tract obstruction (e.g. mitral stenosis, asymmetric septal hypertrophy, malfunctioning prosthetic valve).
* Constrictive pericarditis.
* Complex congenital heart disease.
* Syncopal episodes presumed to be due to uncontrolled life-threatening arrhythmias (asymptomatic arrhythmias including ventricular tachycardia are not exclusion criteria.
* Uncontrolled hypertension.
* Cor pulmonale.
* Heart transplant recipient.
* Other important non-cardiovascular disease(s) expected to limit compliance and/or impact on patient's ability to complete the study, such as: \*history of alcohol or drug abuse, \*psychiatric disorders, \*senility, \*severe physical disability, \*illnesses including terminal stage of cancer and other major systemic illnesses expected to limit the patient's ability to comply with the study protocol and to complete the study.
B: Inclusion Criteria:

* Patients with confirmed symptomatic PE or DVT who have been treated for 6 or 12 months with VKA or rivaroxaban

Exclusion Criteria:

* Legal lower age limitations (country specific)
* Indication for VKA other than DVT and/or PE
* Patients in whom anticoagulant treatment for their index PE or DVT should be continued
* Childbearing potential without proper contraceptive measures, pregnancy or breast feeding. Proper contraceptive measures are defined as a method of contraception with a failure rate \< 1 % during the course of the study (including the observational period). These methods of contraception according to the note for guidance on non-clinical safety studies for the conduct of human trials for pharmaceuticals (CPMP \[Committee for Proprietary Medicinal Products\]/ICH \[International Conference on Harmonization\]/286/95, modification) include consistent and correct use of hormone containing implants and injectables, combined oral contraceptives, hormone containing intrauterine devices, surgical sterilization, sexual abstinence and vasectomy
C: Inclusion Criteria:

* A person who has been diagnosed with acute coronary syndrome and is to undergo a percutaneous coronary intervention.
* A person who is of the legal age of 18 and is mentally competent to provide a signed written informed consent.
* If a woman is of childbearing potential (i.e., before menopause), she must test negative for pregnancy and agree to use a reliable method of birth control.

Exclusion Criteria:

* A person who has had an ischemic stroke within the last 3 months or a hemorrhagic stroke at any time in the past.
* A person who has active internal bleeding or has a history of a bleeding disorder.
* Individuals who are at an increased risk of bleeding based on laboratory criteria evaluated by the treatment physician or on medication that can cause bleeding.
* A person who has liver disease; for example, cirrhosis.
* A person who has a condition such as alcoholism, mental illness, or is drug dependent.
* A person who has cardiogenic shock, a refractory ventricular arrhythmia, or congestive heart failure (class IV).
D: Inclusion Criteria:

* Confirmed acute symptomatic DVT, i.e. proximal or extensive calf-vein thrombosis involving at least the upper third part of the calf veins, without concomitant symptomatic PE
* Written informed consent

Exclusion Criteria:

* Legal lower age limitations (country specific)
* Thrombectomy, insertion of a caval filter, or use of a fibrinolytic agent to treat the current episode of DVT
* Other indication for VKA than PE/DVT
* More than 36 hours pre-randomization treatment with therapeutic dosages of (LMW) heparin or more than a single dose of VKA prior to randomization
* Participation in another pharmacotherapeutic study within the prior 30 days
* Creatinine clearance \< 30 mL/min, impaired liver function (transaminases \> 2 x ULN), or bacterial endocarditis
* Life expectancy \< 3 months
* Active bleeding or high risk for bleeding contraindicating treatment with (LMW) heparin
* Uncontrolled hypertension: systolic blood pressure \> 200 mmHg and diastolic blood pressure \> 110 mmHg
* Pregnancy or childbearing potential without proper contraceptive measures
* Any other contraindication listed in the labeling of warfarin, acenocoumarol, phenprocoumon, fluindione, UFH, enoxaparin, or tinzaparin
* Systemic treatment with azole compounds or other strong CYP3A4 inhibitors (e.g. ketoconazole, fluconazol, itraconazole, HIV protease inhibitors) within 4 days prior to randomization and during the study
