Absorb IV Randomized Controlled Trial
United States, Australia, Canada2,604 participantsStarted 2014-07
Plain-language summary
ABSORB IV is a prospective, randomized (1:1, Absorb BVS to XIENCE), single-blind, multi-center study, registering approximately 2610 subjects from approximately 140 sites in the United States and outside the United States. ABSORB IV is a continuation of ABSORB III (NCT01751906) trial which are maintained under one protocol because both trial designs are related. The data from ABSORB III and ABSORB IV will be pooled to support the ABSORB IV primary endpoint. Both the trials will evaluate the safety and effectiveness of Absorb BVS.
The ABSORB IV Randomized Controlled Trial (RCT) is designed to continue to evaluate the safety and effectiveness as well as the potential short and long-term benefits of Abbott Vascular Absorb™ Bioresorbable Vascular Scaffold (BVS) System, and the Absorb GT1™ BVS System (once commercially available), as compared to the commercially approved, control stent XIENCE.

Inclusion criteria
. Subject must be at least 18 years of age.
. Subject or a legally authorized representative must provide written Informed Consent prior to any study related procedure, per site requirements.
. Subject must have evidence of myocardial ischemia (e.g., silent ischemia, stable or unstable angina, non-ST-segment elevation MI (NSTEMI), OR recent ST-segment elevation MI (STEMI). Patients with stable coronary syndromes can be enrolled any time after symptom onset if eligibility criteria are otherwise met. Patients with acute coronary syndrome can be enrolled under the following conditions:
. Unstable angina or NSTEMI within 2 weeks of the index procedure.
. STEMI \> 72 hours ≤ 2 weeks prior to the index procedure.
. Subjects must be suitable for PCI. Subjects with stable angina or silent ischemia and \< 70% diameter stenosis must have objective signs of ischemia as determined by one of the following: abnormal stress echocardiogram, nuclear scan, electrocardiogram (ECG), positron emission tomography (PET), magnetic resonance imaging (MRI), and/or fractional flow reserve (FFR).
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.
What they're measuring
1
Number of Participants With Target Lesion Failure (TLF)
. Subject must be an acceptable candidate for coronary artery bypass graft (CABG) surgery.
. Female subject of childbearing potential who does not plan pregnancy for up to 1 year following the index procedure. For a female subject of childbearing potential a pregnancy test must be performed with negative results known within 7 days prior to the index procedure per site standard.
Exclusion criteria
. Any surgery requiring general anesthesia or discontinuation of aspirin and/or a P2Y12 receptor inhibitor is planned within 12 months after the procedure.
. Subject has known hypersensitivity or contraindication to device material and its degradants (everolimus, poly (L-lactide), poly (DL-lactide), lactide, lactic acid) and cobalt, chromium, nickel, platinum, tungsten, acrylic and fluoro polymers that cannot be adequately pre-medicated. Subject has a known contrast sensitivity that cannot be adequately pre-medicated.
. Subject has known allergic reaction, hypersensitivity or contraindication to any of the following: aspirin; or clopidogrel and prasugrel and ticagrelor; or heparin and bivalirudin, and therefore cannot be adequately treated with study medications.
. Subject had an acute STEMI (appropriate clinical syndrome with ≥1 mm of ST-segment elevation in ≥2 contiguous leads) within 72 hours of the index procedure.
. Subject has a cardiac arrhythmia identified at the time of screening for which at least one of the following criteria is met:
. Subject requires coumadin or any other agent for chronic oral anticoagulation.
. Subject is likely to become hemodynamically unstable due to their arrhythmia.
. Subject has poor survival prognosis due to their arrhythmia.
