The ENDEAVOR III Trial is a prospective, multi-center, single-blind, randomized trial that enrolled 436 patients at 29 sites in the US. The purpose of this trial is to demonstrate the equivalency of in-segment late lumen loss at 8 months between the Endeavor stent and the Cypher stent for the treatment of single de novo lesions in native coronary arteries 2.5-3.5 mm in diameter. Patients were randomized to receive the Endeavor stent or the Cypher Sirolimus-Eluting Coronary Stent System. Enrollment was completed in September 2004.
To demonstrate the equivalency in in-segment late lumen loss at 8 months between the Endeavor Drug Eluting Coronary Stent System coated with ABT-578 (10 micrograms/mm) and the Cypher Sirolimus-Eluting Coronary Stent System for the treatment of single de novo lesions in native coronary arteries 2.5-3.5 mm in diameter.
