A Clinical Evaluation of Absorb™ BVS, the Everolimus Eluting Bioresorbable Vascular Scaffold in the Treatment of Subjects With de Novo Native Coronary Artery Lesions
In Brief
A clinical study evaluating Absorb BVS and XIENCE for Coronary Artery Disease and 3 related conditions. Completed, enrolled 2,604 participants across 120 sites in 5 countries.
Detailed 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.
Study Details
Timeline
Interventions
* Scaffold diameters: 2.5, 3.0 and 3.5 mm * Scaffold lengths: 8, 12, 18, and 28 mm. Both the 8 mm and 12 mm lengths will be available for the 2.5/3.0 mm diameter Absorb BVS. Only the 12 mm length will be available for the 3.5 mm diameter. * Once Absorb GT1™ BVS System is commercially available, it can also be used in the ABSORB IV trial. Scaffold diameters: 2.5, 3.0 and 3.5 mm of and scaffold lengths: 8, 12, 18, 23, and 28 mm. * The commercially approved CE marked device will be used in geographies where it is commercially available. The commercially approved CE marked 23mm Absorb BVS device will not be used in this study. Bioabsorbable drug eluting stent implantation for improving coronary luminal diameter in patients, including those with diabetes mellitus, with ischemic heart disease due to de novo native coronary artery lesions (length ≤ 24 mm) with a reference vessel diameter of ≥ 2.5 mm and ≤ 3.75 mm.
Commercially approved XIENCE Family Stent System, inclusive of XIENCE V, XIENCE PRIME, XIENCE Xpedition, XIENCE Alpine, XIENCE Pro (OUS only), and XIENCE ProX (OUS only). * Stent diameters: 2.5, 2.75, 3.0, 3.25, 3.5 and 4.0 mm. The 3.25 mm is only available for XIENCE Xpedition * Stent lengths: 8, 12, 15, 18, 23, and 28 mm * For geographies where these devices are commercially available, the investigational sties may use only their locally approved devices To improve coronary luminal diameter in patients, including those with diabetes mellitus, with ischemic heart disease due to de novo native coronary artery lesions (length ≤ 24 mm) with a reference vessel diameter of ≥ 2.5 mm and ≤ 3.75 mm.
