Aspirin Resistance and Percutaneous Coronary Intervention (PCI) (RESIST)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01103440
Recruitment Status : Completed

Brief Summary:
The objective of this study is to evaluate if aggressive antiplatelet therapy would reduce ischemic events in aspirin (ASA) resistant patients after percutaneous coronary intervention (PCI).

Condition or disease Intervention/treatment Phase
Stable Angina Drug: Intravenous Glycoprotein inhibitor + ASA, Clopidogrel Drug: Antiplatelet Therapy (ASA, Clopidogrel) Phase 2

Detailed Description:
This is the first US based randomized double blinded prospective study using triple antiplatelet therapy and double dose plavix maintenance dose in aspirin resistant patients undergoing elective PCI through femoral access. The primary outcome of this study is an elevation of cardiac enzymes within 24 hours after the PCI with a secondary outcome of a composite of major adverse cardiac events of death, MI, stent thrombosis and urgent revascularization and bleeding up to 30 days.

Drug Information available for: Clopidogrel

Arm Intervention/treatment
Conventional Strategy
Patient receive 325 mg ASA orally and loading does of 600mg Clopidogrel at time of procedure
Drug: Antiplatelet Therapy (ASA, Clopidogrel)
Standard antiplatelet PCI treatment
Other Names:
  • Thienopyridines
  • Ticlopidine
  • Clopidogrel
  • Prasugrel

Active Comparator: Aggressive Strategy
Patient receive 325mg ASA orally and loading does of 600mg Clopidogrel at time of procedure with addition of IV GP IIb/IIIa inhibitor bolus intra procedurally
Drug: Intravenous Glycoprotein inhibitor + ASA, Clopidogrel
IV Glycoprotein IIb/IIIa inhibitor bolus intra procedurally
Other Names:
  • Cangrelor
  • Abciximab
  • Eptifibatide
  • Tirofiban

Primary Outcome Measures :
  1. Number of Participants With Elevation of Cardiac Enzyme [ Time Frame: 24 hours ]
    Number of participants with peri-procedural biomarker elevation defined as any elevation above baseline of CK-MB or Tn-I within 24 hours after completion of the procedure.

Secondary Outcome Measures :
  1. Number of Participants With Major Adverse Cardiac Event (MACE) [ Time Frame: 30 days ]
    Number of participants with MACE which is any event of Death, MI, Stent Thrombosis, Urgent Revascularization, Bleeding. Major adverse cardiac events (MACE), defined as the composite of death, MI (CK-MB > 3 times normal), urgent revascularization and definite or probable stent thrombosis (ST) within 30 days. Stent thrombosis was defined according to the new academic research consortium definitions; 2) bleeding complications within 30 days. Major bleeding was defined as intracranial or intraocular bleeding or a drop in hemoglobin > 5 g/dL. Minor bleeding was defined as hemorrhage at the access site requiring intervention, hematoma with a diameter of at least 5 cm, a reduction in hemoglobin levels of at least 4 g/dL without an overt bleeding source or at least 3 g/dL with such a source, reoperation for bleeding or transfusion of a blood product.
