Brief Summary

Acute Coronary Syndrome (ACS) is triggered by the rupture of an atherosclerotic plaque that results in a platelet aggregation reaction in the coronary artery. The administration of antiplatelet agents starting from the acute phase of the disease has helped reduce the risk of ischemic relapse both during initial and long-term hospitalization.

Management of clopidogrel following an ischemic event has been the subject of several treatment regimens ranging from a single continuous dose to a sequential double dose of between 7 and 30 days. The CURRENT-OASIS 7 therapeutic trial showed a benefit of clopidogrel double dose in reducing the risk of myocardial intervention (MI) and the composite outcome: cardiovascular mortality, MI, or stroke (CVA/TIA) at 30 days. However, the study protocol was interested in all ACSs, regardless of the Type 2 Diabetes Mellitus (T2DM) status in selected patients. Also, doubling of clopidogrel dose was maintained over 7 days after angioplasty. The literature describes an increased cardiovascular risk in type II diabetics in secondary prevention. No previous study has evaluated the effect of clopidogrel double dose given for 1 month on the reduction of this risk in the long-term in diabetic patients.

Thus, the objective of this study is to evaluate the efficacy and safety of clopidogrel double dose, given for 1 month in ACS in the diabetic patient.

Detailed Description

The study is an open label, multicentric clinical trial. Collected data are managed by the DACIMA Clinical Suite®, the electronic data capture platform which complies with the FDA 21 CFR part 11 requirements (Food and Drug Administration 21 Code of Federal Regulations part 11), the HIPAA specifications (Health Insurance Portability and Accountability Act), and the ICH standards (International Conference on Harmonisation).

Number Of Arms 2
Arm Group

Arm group label: Arm 1 (single dose)

Arm group type: Active Comparator

Description: Will receive a clopidogrel loading dose of 600 mg PO, then a daily dose of clopidogrel 75 mg PO until the angioplasty is performed. After coronary intervention, a daily dose of clopidogrel 150 mg PO for 7 days will be given, followed by a daily single dose of clopidogrel (75 mg PO) for 21 days. Maintenance therapy will be clopidogrel daily dose of 75 mg PO thereafter, until the end of the study.

Arm group label: Arm 2 (double dose)

Arm group type: Active Comparator

Description: Will receive a clopidogrel loading dose of 600 mg PO, then a daily dose of clopidogrel 75 mg PO until the angioplasty is performed. After coronary intervention, a daily dose of clopidogrel 150 mg PO for 7 days will be given, followed by a daily double dose of clopidogrel (150 mg PO) for 21 days. Maintenance therapy will be clopidogrel daily dose of 75 mg PO thereafter, until the end of the study.
