Safety Concern Continues with Abbott’s Absorb Scaffold: FDA
An FDA safety update says that interim study results through three years from a pivotal clinical trial (ABSORB III) continue to show an increased rate of major adverse cardiac events and scaffold thrombosis in patients receiving Abbott Vascular’s Absorb GT1 Bioresorbable Vascular Scaffold (BVS), when compared to patients treated with the company’s metallic XIENCE drug-eluting stent. Specifically, data show a 13.4% rate of major adverse cardiac events (e.g., cardiac death, heart attack, or the need for an additional procedure to re-open the treated heart vessel) in patients treated with the scaffold at three years, compared with 10.4% in patients treated with the XIENCE stent. The update says the company stopped global marketing of the Absorb scaffold last month.
