United States870 participantsStarted 2009-08
Plain-language summary
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.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
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. Complia…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
