The ABSORB III RCT is a prospective randomized, single-blind, multi-center trial. It is the
pivotal trial to support the US pre-market approval (PMA) of Absorb™ Bioresorbable Vascular
The ABSORB III includes additional two trials i.e. ABSORB III PK sub-study and ABSORB IV RCT
trial which are maintained under one protocol because both trial designs are related, ABSORB
IV is the continuation of ABSORB III and 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.

Prior PCI within the non-target vessel or any peripheral intervention is acceptable if performed anytime >30 days before the index procedure, or between 24 hours and 30 days before the index procedure if successful and uncomplicated. 9. Future staged PCI either in target or non-target vessels or subject requires future peripheral interventions < 30 days after the index procedure. 10.

Subject is receiving immunosuppressant therapy or has known immunosuppressive or severe autoimmune disease that requires chronic immunosuppressive therapy (e.g., human immunodeficiency virus, systemic lupus erythematosus, etc.). Note: corticosteroids are not included as immunosuppressant therapy. 13. Subject has previously received or is scheduled to receive radiotherapy to a coronary artery (vascular brachytherapy), or the chest/mediastinum. 14. Subject is receiving or will require chronic anticoagulation therapy (e.g., coumadin, dabigatran, apixaban, rivaroxaban or any other agent for any reason). 15. Subject has a platelet count < 100,000 cells/mm3 or > 700,000 cells/mm3. 16. Subject has a documented or suspected hepatic disorder as defined as cirrhosis or Child-Pugh ≥ Class B. 17. Renal insufficiency. NOTE: Estimated GFR can be based on Modification of Diet in Renal Disease (MDRD) equation or Cockcroft-Gault equation (CCG). 18. High risk of bleeding for any reason; has a history of bleeding diathesis or coagulopathy; has had a significant gastro-intestinal or significant urinary bleed within the past six months. 19. Cerebrovascular accident or transient ischemic neurological attack (TIA) within the past six months, or any prior intracranial bleed, or any permanent neurologic defect, or any known intracranial pathology (e.g., aneurysm, arteriovenous malformation, etc.). 20. Extensive peripheral vascular disease that precludes safe 6 French sheath insertion. Note: femoral arterial disease does not exclude the patient if radial access may be used. 21. Subject has life expectancy < 5 years for any non-cardiac cause or cardiac cause. 22. Subject is in the opinion of the Investigator or designee, unable to comply with the requirements of the study protocol or is unsuitable for the study for any reason. This includes completion of Patient Reported Outcome instruments. 23. Subject is currently participating in another clinical trial that has not yet completed its primary endpoint. 24. Vulnerable population. Angiographic Inclusion Criteria: 1. One or two de novo target lesions: 1. If there is one target lesion, a second non-target lesion may be treated but the non-target lesion must be present in a different epicardial vessel, and must be treated first with a successful, uncomplicated result prior to randomization of the target lesion. 2. If two target lesions are present, they must be present in different epicardial vessels and both must satisfy the angiographic eligibility criteria. 3. The definition of epicardial vessels means the LAD, LCX and RCA and their branches. Thus, the patient must not have lesions requiring treatment in e.g. both the LAD and a diagonal branch. 2. Target lesion(s) must be located in a native coronary artery with a visually estimated or quantitatively assessed %DS of ≥ 50% and < 100% with a TIMI flow of ≥1 and one of the following: stenosis ≥ 70%, an abnormal functional test (e.g. fractional flow reserve, stress test), unstable angina or post-infarct angina. 1. Lesion(s) must be located in a native coronary artery with RVD by visual estimation of ≥ 2.5 mm and ≤ 3.75 mm. 2. Lesion(s) must be located in a native coronary artery with length by visual estimation of ≤ 24 mm. 3. For Lead-In subjects with 3.0x18 mm Absorb BVS: lesion(s) must be located in a native coronary artery with RVD by visual estimation of ≥ 2.75 mm and ≤ 3.25 mm. The lesion length by visual estimation is ≥ 8 mm and ≤ 14 mm. Angiographic Exclusion Criteria: All exclusion criteria apply to the target lesion(s) or target vessel(s). 1. Lesion which prevents successful balloon pre-dilatation, defined as full balloon expansion with the following outcomes: 1. Residual %DS is a maximum of < 40% (per visual estimation), ≤ 20% is strongly recommended. 2. TIMI Grade-3 flow (per visual estimation). 3.

Lesion located within 3 mm of the origin of the LAD or LCX. 5. Lesion involving a bifurcation with a: 1. side branch ≥ 2 mm in diameter, or 2. side branch with either an ostial or non-ostial lesion with diameter stenosis > 50%, or 3. side branch requiring dilatation. 6. Anatomy proximal to or within the lesion that may impair delivery of the Absorb BVS or XIENCE stent: 1. Extreme angulation (≥ 90°) proximal to or within the target lesion. 2. Excessive tortuosity (≥ two 45° angles) proximal to or within the target lesion. 3. Moderate or heavy calcification proximal to or within the target lesion. If IVUS used, subject must be excluded if calcium arc in the vessel prior to the lesion or within the lesion is ≥ 180°. 7. Vessel contains thrombus as indicated in the angiographic images or by IVUS or OCT. 8. Lesion or vessel involves a myocardial bridge. 9. Vessel has been previously treated with a stent at any time prior to the index procedure such that the Absorb BVS or XIENCE would need to cross the stent to reach the target lesion. 10.
