The highly anticipated first results of the RESOLUTE All Comers study were presented on 25 May 2010 during the late-breaking clinical trial session of the 2010 EuroPCR meeting. In this novel 2,292-patient randomised trial, the Resolute zotarolimus-eluting stent (Medtronic) was found to be as safe and effective as the Xience V everolimus-eluting stent (Abbott).
This is the first major device study to directly compare Resolute drug-eluting stent (DES) to the current market-leading platform. The design of the RESOLUTE All Comers study included patients that are not typically enrolled in comparative clinical studies, making the results highly representative of real-world clinical practice.
At one year, the Resolute DES was shown to be as effective as the Xience DES in reducing the need for repeat procedures, and both second-generation stents were associated with low and similar rates of death from cardiac causes and heart attacks attributed to the treated vessel.
Available in many countries outside the United States and Japan, the Resolute drug-eluting stent is indicated for improving coronary luminal diameter and reducing restenosis in patients with symptomatic ischemic heart disease in de novo coronary artery lesions in native coronary arteries with a reference vessel diameter of 2.25mm to 4mm. In the United States, the Resolute DES is not available for sale and is limited by federal law to investigational use only.
The primary endpoint of the study was target lesion failure (TLF) – a composite of cardiac death, target vessel myocardial infarction and clinically driven target lesion revascularisation. The Resolute DES posted TLF rates of 8.2% vs. 8.35% for the Xience DES (non-inferiority p=<0.001).The manuscript of the trial’s results has been accepted for publication by a major medical journal and is expected to be published soon.
“These compelling results were achieved in a challenging patient population that is representative of every day clinical practice,” said Patrick Serruys, director of the Thoraxcenter at Erasmus University in Rotterdam, The Netherlands, and one of three principal investigators for RESOLUTE All Comers. “Given the rigorous design and conduct of this novel, multicenter randomized clinical trial, it is clear that the Resolute drug-eluting stent has distinguished itself as an important treatment option for a wide range of patients undergoing percutaneous coronary intervention.”
RESOLUTE All Comers is one part of the comprehensive Resolute clinical programme, which will enrol a total of more than 6,000 patients worldwide across a series of single-arm and randomised controlled trials, including RESOLUTE, RESOLUTE US, RESOLUTE International and RESOLUTE Japan. The Resolute clinical program is a collaborative effort involving hundreds of medical centers in more than 25 countries across Europe, Asia, the Pacific Rim, the Middle East, Africa, Latin America and North America.
