Study on Safety and Effectiveness of Three Doses of Argatroban as Anticoagulant in Percutaneous Coronary Intervention (PCI)
A Randomised, Open, Parallel-group, Multicentre Study to Examine the Safety and Effectiveness of Three Doses of Argatroban as Anticoagulant in Combination With Clopidogrel and Aspirin in Patients Undergoing Elective Percutaneous Coronary Intervention in Comparison With Unfractionated Heparin, Clopidogrel and Aspirin

Brief Summary
This is a phase II multi-centre study in 140 patients undergoing elective PCI to obtain the information on dose-response of argatroban in pharmacodynamic markers and to assess the anticoagulation, safety and efficacy of argatroban in reference to unfractionated heparin, in combination with dual antiplatelet therapy.

You may qualify if:
Male or female (women of child bearing potential must have a negative pregnancy test prior to entry into the study)
Registry-reported names are shown in full. Names without a link have not yet been matched to a Syfrah profile.
Diagnosis of stable coronary artery disease (CAD) or unstable angina (troponin negative, i.e. within the normal range for the study site) with low to moderate anatomic risk and a requirement for elective percutaneous coronary angioplasty or stent insertion with an approved device in one or more de novo-treated or re-stenotic lesions in native vessels
Signed written informed consent
You may not qualify if:
Any condition which, in the investigator's opinion, contraindicates the use of argatroban, heparin or clopidogrel or endangers the patient if he/she participated in this study.
Known cirrhosis, hepatitis, clinically significant hepatic disorder, or history of hepatic disorder. Hepatic disorder is defined as having levels of liver function tests (bilirubin, Aspartate Aminotransferase (Serum Glutamate Oxaloacetate Transaminase)(AST (SGOT)), Alanine Aminotransferase (Serum Glutamate Pyruvate Transaminase)(ALT (SGPT)) greater than 3.0 times above the upper limit of the normal range of local laboratory.
Patients not currently taking aspirin
Renal insufficiency, defined as serum creatinine greater than 2.0 mg/dL (greater than 177mmol/L)
Platelets less than 125,000/ml
If already taking any form of heparin prior to study enrolment, Activated Partial Thromboplastin Time(aPTT) equal or greater than 35 sec or ACT greater than 160 sec
Use of low molecular heparin (LMWH) during 12 h prior to PCI
If taking oral anticoagulant medication prior to study enrolment, International Normalised Ratio(INR) greater than 1.2
Q wave MI with cardiogenic shock or thrombolytic therapy within 72 h of study dosing
Use of Glycoprotein IIb / IIIa(GPIIb/IIIa) inhibitors within prior 3 weeks
Documented coagulation disorder or bleeding diathesis
Lumbar puncture within the past 2 weeks
History of previous cerebral aneurysm, haemorrhagic stroke, or thrombotic stroke within the past 6 months
