A Study to Evaluate the Efficacy and Safety of BuMA Supreme Drug Eluting Stent(DES) (RCT)
September 10, 2021 updated by: Sino Medical Sciences Technology Inc.
A Prospective, Multicenter Trial Program in China to Evaluate the Efficacy and Safety of BuMA Supreme (eG Grafting) Biodegradable Polymer Sirolimus Eluting Stent in Patients With de Novo Coronary Lesions, RCT Trial
PIONEER-II RCT trial is a prospective, multicenter, randomized, non-inferiority registry trial.
539 subjects from about 40 interventional cardiology centers in China will be enrolled to evaluate In-stent late lumen loss(LLL) as the primary endpoint at 9 months.
And all the subjects will be followed up to 5 years to attain the data of the secondary endpoints.
