Absorb III Randomized Controlled Trial (RCT)

Objective: The pivotal trial to support the US pre-market approval (PMA) of Absorb BVS. ABSORB III will evaluate the safety and effectiveness of the Absorb BVS System compared to the XIENCE in the treatment of subjects, including those with diabetes mellitus, with ischemic heart disease caused by up to two de novo native coronary artery lesions in separate epicardial vessels.

General inclusion Criteria:

  1. Subject must be at least 18 years of age to participate in clinical research.
  2. Subject or a legally authorized representative must provide written Informed Consent prior to any study related procedure, per site requirements.
  3. Subject must have evidence of myocardial ischemia (e.g., stable, unstable angina, post-infarct angina or silent ischemia) suitable for elective PCI. Subjects with stable angina or silent ischemia and < 70% diameter stenosis must have objectives sign of ischemia as determined by one of the following, echocardiogram, nuclear scan, ambulatory ECG or stress ECG). In the absence of noninvasive ischemia, FFR must be done and indicative of ischemia.
  4. Subject must be an acceptable candidate for coronary artery bypass graft (CABG) surgery.
  5. 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.
  6. Female subject is not breast-feeding at the time of the screening visit and will not be breast-feeding for up to 1 year following the index procedure.
  7. Subject agrees to not participate in any other investigational or invasive clinical study for a period of 1 year following the index procedure.
