Brief Summary:
This purpose of this study is to measure platelet response to ticagrelor and eptifibatide bolus-only compared with ticagrelor and eptifibatide bolus plus 2-hour infusion administrated after cardiac catheterization in patients undergoing non-emergent percutaneous coronary intervention.

Condition or disease Intervention/treatment Phase
Acute Coronary Syndrome Drug: Ticagrelor Drug: Eptifibatide Phase 2

Detailed Description:
In this study, 70 patients with Acute Coronary Syndrome who are undergoing non-emergent percutaneous coronary intervention (PCI) will be randomized to ticagrelor loading dose and eptifibatide bolus-only versus ticagrelor loading dose and eptifibatide bolus plus 2 hour infusion administrated after cardiac catheterization, but before PCI. Platelet function testing will be performed at baseline and follow-up.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 70 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)

Active Comparator: Ticagrelor & Eptifibatide bolus+infusion
Ticagrelor 180 mg i.v. Eptifibatide (2 boluses 180µg/Kg, 10 min apart, followed by 2µg/Kg/min infusion for 2 hours)
Drug: Ticagrelor
Ticagrelor loading dose

Drug: Eptifibatide
i.v. infusion
Other Name: Integrilin




Primary Outcome Measures :
  1. Change in Percent Inhibition of Platelet Aggregation (%IPA) [ Time Frame: Baseline and 2 hours ]
    Change from baseline in %IPA at 2 hours after stimulation with 20µM ADP (µM-micromolar, ADP-Adenosine diphosphate), measured in blood by an aggregometer among patients randomized to ticagrelor and 2 boluses of eptifibatide vs. ticagrelor and 2 boluses plus infusion of eptifibatide.


Secondary Outcome Measures :
  1. High On-treatment Platelet Reactivity (HPR) [ Time Frame: Comparing baseline and follow-up (2 hours) ]
    Percentage of participants with HPR. HPR is defined as platelet aggregation >59% in response to 20 µM ADP.

  2. Bleeding Complications [ Time Frame: up to 24 hours ]
    Number of subjects that developed gastrointestinal bleeding after Percutaneous Coronary Intervention (PCI). These subjects were categorized under Bleeding Academic Research Consortium 3b. Type 3b bleeding includes overt bleeding plus a hemoglobin drop of ≥5 g/dL (provided the hemoglobin drop is related to bleeding), cardiac tamponade, bleeding requiring surgical intervention for control (excluding dental/nasal/skin/hemorrhoid), and bleeding requiring intravenous vasoactive drugs.

  3. Periprocedural Myocardial Infarction (PMI) [ Time Frame: Up to 24 hours ]
    Number of subjects that developed PMI. Periprocedural myocardial infarction (PMI) was defined as an increase in troponin I values >5 x 99th percentile the upper limit of normal in patients with normal baseline value on admission, or a rise of troponin I values >20% after PCI if the baseline value was elevated.

Criteria

Inclusion Criteria:

For inclusion in the study subjects should fulfill the following criteria:

  • age >60 years
  • previous myocardial infarction or Coronary-Artery Bypass Grafting [CABG];
  • coronary artery disease with stenosis of ≥50% in at least two vessels;
  • previous ischemic stroke, transient ischemic attack, carotid stenosis of at least 50%, or cerebral revascularization;
  • diabetes mellitus;
  • peripheral arterial disease;
  • or chronic renal dysfunction, defined as a creatinine clearance of <60 ml per minute per 1.73 m2 of body surface area).
  • patients with symptoms of unstable angina lasting ≥10 min and either an elevated troponin I level or newly developed ST-segment depression of 1 mm or transient ST-segment elevation of 1 mm will also be included.

Exclusion Criteria:

Subjects should not enter the study if any of the following exclusion criteria are fulfilled:

  • Patients with active pathological bleeding or a history of intracranial bleeding;
  • patients with planned to urgent coronary artery bypass graft surgery;
  • severe hepatic impairment;
  • concomitant therapy with a strong cytochrome P-450 3A inhibitors, where 3A is s subfamily of the cytochrome P450 superfamily of genes;
