XIENCE V® USA Dual Antiplatelet Therapy (DAPT) Cohort
XIENCE V® Everolimus Eluting Coronary Stent System USA Post- Approval Study (XIENCE V® USA DAPT Cohort) (XVU-AV DAPT)

XIENCE V USA is a prospective, multi-center, multi-cohort postapproval study. The objectives of this study are

  • To evaluate XIENCE V EECSS continued safety and effectiveness during commercial use in real world settings, and
  • To support the Food and Drug Administration (FDA) dual antiplatelet therapy (DAPT) initiative. This initiative is designed to evaluate the composite of all death, myocardial infarction (MI) and stroke (MACCE) and the survival of patients that are free from Academic Research Consortium (ARC) definite or probable stent thrombosis (ST) and that have been treated with drug eluting stents (DES) and extended dual antiplatelet therapy.

This prospective, multi-center, randomized, double-blind AV-DAPT study cohort is designed to collect data to support the FDA DAPT initiative. The protocol for AV-DAPT cohort is designed according to the HCRI-DAPT study protocol, Study IDE # G080186. Patients from the additional 3,000 treated with the XIENCE V EECSS who are free from events (death, MI, repeat coronary revascularization, stroke, ST, or major bleeding - "severe" or "moderate" by GUSTO classification) in the first year after the index procedure, and are compliant with DAPT will be identified as prospective patients for the cohort. Patients who are considered as part of the AV-DAPT cohort will continue with Aspirin therapy and will be randomized to 18 months of active treatment with thienopyridines or placebo 12 months after index procedure. Clinical follow-up will occur at 15, 24, 30 and 33 months. These patients will be followed by Abbott Vascular.

The remaining patients from the additional 3,000 patients who do not participate in AV-DAPT cohort will be followed for the first year only. A study completion form will be filled out and the patients will not be followed beyond their 1 year visit.

Inclusion Criteria:

  • Patients who are enrolled into the XIENCE V USA Study Phase I
  • The patient agrees to participate in this study by signing the Institutional Review Board (IRB) approved informed consent form. Alternatively, the patient's legally authorized representative agrees to the patient's participation in this study and signs the informed consent form.

Exclusion Criteria:

  • The inability to obtain an informed consent is an exclusion criterion.

Patients must meet the following criteria to be eligible for randomization in the study:

  • Patient is "12 Month Clear": "12-Month Clear" patients are free from death, MI, stroke, repeat coronary revascularization, major bleeding - "severe" or "moderate" by GUSTO classification, and ST 12 months after stent implantation. Staged PCI is allowed (same stent type as index); repeat PCI and peri-procedural myocardial infarction occurring with the index procedure or repeat procedure within the first 6 weeks will not be considered exclusionary events for the definition of "12 Month Clear".
  • Patient is "DAPT Compliant": During the open label portion of this study (time 0-12 months), a patient is considered compliant with the thienopyridine therapy for the purposes of eligibility if they take between 80% and 120% of the prescribed drug in a given period without an interruption of therapy longer than 14 days. This information will be ascertained via data collected at the patient interviews at 6 and 12 months post-procedure. Compliance at both time points is required to be considered "clear".
  • Patient completes 1 year visit within ± 30 days window.

Patients will be excluded from randomization if any of the following criteria are met:

  • Pregnant women.
  • Switched thienopyridine type or dose within 6 months prior to randomization. Note: Thienopyridine switching during the open label portion of this study is discouraged.
  • PCI or cardiac surgery between 6 weeks post index procedure and randomization.
  • Planned surgery necessitating discontinuation of antiplatelet therapy within the 21 months following randomization.
  • Current medical condition with a life expectancy of less than 3 years.
  • Patients on warfarin or similar anticoagulant therapy.
