Ticagrelor and Eptifibatide Bolus-Only Versus Ticagrelor and Eptifibatide Bolus Plus Abbreviated Infusion

January 9, 2017 updated by: Massoud Leesar, University of Alabama at Birmingham

Pharmacodynamic Effects of Ticagrelor and Eptifibatide Bolus-Only Versus Ticagrelor and Eptifibatide Bolus Plus Abbreviated Infusion in Patients Undergoing Percutaneous Coronary Intervention

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.

Study Overview

Status

Completed

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.

Description

Inclusion Criteria:

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

  • Provision of informed consent prior to any study specific procedures
  • Males and females aged 19 years and older
  • Congruent to the PLATO trial, at least two of the following three criteria have to be met:
  • ST-segment changes on electrocardiography, indicating ischemia; (In electrocardiography, the ST segment connects the QRS complex and the T wave and has a duration of 0.080 to 0.120 sec (80 to 120 ms).
  • a positive test of a biomarker, indicating myocardial necrosis; or one of several risk factors;
  • 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;
  • surgery<4 weeks;
  • the use of any thienopyridine (within the previous two weeks);
  • upstream use of Glycoprotein (GP) IIb/IIIa inhibitors;
  • bleeding diathesis or major bleeding episode within 2 weeks;
  • a need for oral anticoagulation therapy;
  • thrombocytopenia;
  • presence of thrombus in the coronary artery; incessant chest pain or hemodynamic instability;
  • and patients with glomerular filtration rate (GFR)<30 mL/min or on hemodialysis.
  • maintenance dose of aspirin above 100mg
  • history of allergies to Ticagrelor
  • patients at increased risk of bradycardic events (e.g., patients who have sick sinus syndrome, 2nd or 3rd degree Atrioventricular block (AV block), or bradycardic related syncope and not protected with a pacemaker
  • women who are pregnant or breastfeeding

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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.
Baseline and 2 hours

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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.
Comparing baseline and follow-up (2 hours)
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.
up to 24 hours
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.
Up to 24 hours
