This study aims to demonstrate non-inferiority of Pidogrel ® compared to Plavix ® in patients with coronary disease:

  • Primary Outcome Measures: measure of platelet reactivity by VerifyNow assay after 600 mg loading dose or after the last maintenance dose (75 mg).
  • Secondary Outcome Measures: Time to first occurrence of major cardio-vascular events (MACE).
  • Safety Criteria: severe bleeding (GUSTO scale).

Primary Outcome Measures:
  • - study the respective effects of Pidogrel ® and Plavix ® on platelet aggregation through the test VerifyNow ® - Time to first occurrence of post-randomization major adverse cardiac events (MACE) [ Time Frame: 06 months ] [ Designated as safety issue: Yes ]

Enrollment: 219
Study Start Date: April 2010
Study Completion Date: July 2011
Primary Completion Date: June 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: plavix
patient treated by the princeps
Drug: Plavix
Plavix(R) 75 mg/day for period ranging from 1 to 6 months.
Active Comparator: Pidogrel
patient treated by Pidogrel
Drug: Pidogrel
Pidogrel(R)75 mg/day for period ranging from 1 to 6 months.

Detailed Description:

after randomization of patients in both groups (Plavix or Pidogrel), the measure of platelet activity by the VerifyNow assay, 4 to 12 hours after the loading dose of 600mg or after the last dose of clopidogrel for patients on maintenance dose. The VerifyNow assay will determine: - The PRU:-P2Y12 Reaction Units-

-% Of platelet inhibition It will be considered low responder or clopidogrel resistant patient with PRU> 235 or %inhibition <15%.

Monitoring of patients included in the study will take place over a period of 12 months, MACE will be notified and dated. MACE criteria are: angina, myocardial infarction, coronary angioplasty, coronary artery bypass graft, and stroke.

Each hemorrhagic event will be notified and classified according to the GUSTO scale.
