Objectives This study sought to demonstrate the noninferiority of polymer-free amphilimus-eluting stents (Cre8, CID, Saluggia, Italy) versus permanent-polymer paclitaxel-eluting stents (Taxus Liberte, Boston Scientific, Natick, Massachusetts) in de novo percutaneous coronary intervention. Background Although the efficacy of the drug-eluting stent has been well established, the risk-benefit balance is still suboptimal, and the safety of polymers remains uncertain. Methods Patients undergoing percutaneous coronary intervention for de novo lesions were randomly assigned 1:1 to Cre8 or Taxus Liberte stents. Primary endpoint was 6-month angiographic in-stent late lumen loss (LLL) within a noninferiority scope. Six-month intravascular ultrasound was performed in 20% of the patients. All patients will be clinically followed up to 5 years. Results Out of 323 patients enrolled, 162 received Cre8 and 161 Taxus Liberte stents. In-stent LLL was significantly lower in Cre8 group (0.14 +/- 0.36 mm vs. 0.34 +/- 0.40 mm, p noninferiority <0.0001, p superiority <0.0001). Clinical endpoints (cardiac death, myocardial infarction, target lesion revascularization, and stent thrombosis) up to 12 months did not differ significantly between the groups. Conclusions The Cre8 stent in de novo lesions showed significantly lower in-stent LLL at 6 months than the Taxus Liberte stent did, with a trend toward better 12-month clinical safety and efficacy results.
