TAILored Versus COnventional AntithRombotic StratEgy IntenDed for Complex HIgh-Risk PCI

Phase 4
Completed
Conditions
Coronary Stenoses
Interventions
Drug: Conventional antithrombotic strategy
Drug: Tailored antithrombotic strategy
Registration Number
NCT03465644
Lead Sponsor
Duk-Woo Park, MD
Brief Summary

This study evaluates the efficacy and safety of tailored antithrombotic therapy with early (\<6-month post-PCI) intensified (low-dose ticagrelor \[120 mg loading, then 60 mg bid maintenance\] and aspirin) and late (\>6-month post-PCI) deescalated (clopidogrel alone) strategy in patients undergoing high-risk complex PCI as compared with standard Dual Antiplatelet Therapy(aspirin and clopidogrel for 12 months).

All
Target Recruitment
2018
Inclusion Criteria
  1. Age 19 and more

  2. Subjects who scheduled for percutaneous coronary intervention(PCI) with contemporary drug-eluting stent

  3. Patients must have at least one of any features of complex high-risk anatomic, procedural, or clinical-related factors;

    • Clinical factors: diabetes, chronic kidney disease (i.e. creatinine clearance <60 mL/min), or low left ventricular ejection fraction (<40%) or
    • Lesion- or procedure-related factors: left main PCI, chronic total occlusion, bifurcation lesion requiring two-stent technique, severe calcification, diffuse long lesion (lesion length ≥ at least 30 mm), multi-vessel PCI (≥ 2 vessels requiring stent implantation), ≥3 requiring stent implantation, ≥ 3 lesions will be treated, or predicted total stent length for revascularization > 60 mm
  4. The patient or guardian agreed to the study protocol and the schedule of clinical follow-up and provided informed, written consent, as approved by the appropriate institutional review board/ethical committee of the respective clinical site.

Exclusion Criteria
  1. Enzyme-positive Acute myocardial infarction (non-ST-elevation myocardial infarction (NSTEMI) or ST Elevation Myocardial Infarction (STEMI))

  2. Contraindication to aspirin or P2Y12 inhibitors (ticagrelor or clopidogrel)

  3. Use of Gp IIb/IIIa inhibitors at randomization

  4. Cardiogenic shock

  5. Treatment with only bare-metal stent (BMS) or balloon angioplasty during the index procedure.

  6. Requirements for chronic oral anticoagulation (warfarin or Non-vitamin K antagonist oral anticoagulant (NOACs))

  7. Active bleeding or extreme-risk for major bleeding (e.g. active peptic ulcer disease, gastrointestinal pathology with a high risk for bleeding, malignancies with a high risk for bleeding)

  8. History of intracranial hemorrhage or intracranial aneurysm

  9. Planned surgery within 180 days

  10. Severe liver disease (ascites and/or coagulopathy) or Dialysis-dependent renal failure at screening

  11. Platelet count <80,000 cells/mm3 or hemoglobin level <10 g/dL

  12. At risk of bradycardia (subjects with sinus node dysfunction or atrioventricular block more than 2nd degree but without a permanent pacemaker)

  13. Use of strong cytochrome P-450 3A inhibitor or inducers within 2 week of the date of enrollment

    : ketoconazole, clarithromycin, nefazodone, ritonavir, atazanavir, rifampin/rifampicin, rifabutin, dexamethasone, phenytoin, carbamazepine, phenobarbital

  14. Pregnant and/or lactating women.

  15. Concurrent medical condition with a life expectancy of less than 1 years

  16. Active participation in another investigational study of a drug or device that has not completed the primary endpoint or follow-up period

  17. Inability to provide written informed consent or participate in long-term follow-up
