NCT02494284

Brief Summary

The purpose of this study is to compare short-term (6-month Dual Anti Platelet Therapy(DAPT) followed by clopidogrel monotherapy) vs. standard long-term dual antiplatelet strategies (24-month DAPT followed by aspirin monotherapy) on clinically relevant bleeding complications (Bleeding Academic Research Consortium(BARC) type 2, 3, or 5)31 in patients after zotarolimus-eluting stent implantation.

Eligibility Criteria

Age19 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Men or women at least 19 years of age
  • Patients with stable coronary artery disease who were successfully treated with zotarolimus-eluting stents
  • Patients without major bleeding or MACE (myocardial infarction, stent thrombosis, stoke, repeat revascularization) within 6 months after zotarolimus-eluting stent placement
  • The patient or guardian agrees to the study protocol and the schedule of clinical follow-up, and provides informed, written consent, as approved by the appropriate Institutional Review Board/Ethical Committee of the respective clinical site.

You may not qualify if:

  • Persistent thrombocytopenia (platelet count \<100,000/µl)
  • A known intolerance to a study drug (aspirin, clopidogrel)
  • Patients requiring long-term oral anticoagulants or cilostazol
  • Patients presented with acute myocardial infarction (STEMI or NSTEMI) at the time of index procedure
  • Planned cardiac surgery (e.g., CABG, valve repair or replacement, or aneurysmectomy) or planned major non-cardiac surgery within 18 months after procedure
  • Bare-metal stent implantation at the time of index procedure
  • Chronic disease requiring treatment with oral, intravenous, or intra-articular corticosteroids (use of topical, inhaled, or nasal corticosteroids is permissible).
  • A diagnosis of cancer in the past 2 years or current treatment for the active cancer.
  • Any clinically significant abnormality identified at the screening visit, physical examination, laboratory tests, or electrocardiogram which, in the judgment of the Investigator, would preclude safe completion of the study.
  • Hepatic disease or biliary tract obstruction, or significant hepatic enzyme elevation (ALT or AST \> 3 times upper limit of normal).
  • History of adult asthma manifested by bronchospasm in the past 6 months, or currently taking regular anti-asthmatic medication(s).
  • Unwillingness or inability to comply with the procedures described in this protocol.
  • Patients pregnant or breast-feeding or child-bearing potential.
