Safety and Effectiveness of the Orsiro Sirolimus Eluting Coronary Stent System in Subjects With Coronary Artery Lesions

The BIOTRONIK BIOFLOW-V clinical trial is a prospective, multicenter, randomized, controlled trial combining data on the randomized subjects with data from two historical studies by employing a Bayesian approach. Subjects with CAD that qualify for PCI with stenting will be screened per the protocol inclusion and exclusion criteria to achieve a total of up to 1,400 randomized subjects. Eligible subjects will be randomized in a 2:1 ratio, stratified by study center, to undergo percutaneous coronary revascularization with either the Orsiro Sirolimus Eluting Stent System (treatment group) or the Xience Everolimus Eluting Stent System (control group). Subjects may receive treatment of up to three target lesions, one or two target lesions per target vessel, for a maximum of two target vessels. The target lesion(s) must be de novo or restenotic lesion(s) of ≤ 36 mm in length in native coronary artery(ies), with a reference vessel diameter of 2.25-4.0 mm. Treatment of restenotic lesions is allowed provided that the target lesion was previously treated with PTCA only. All treatment with study stents is to be performed during a single index procedure. Note: Concurrent treatment of non-target lesions during the index procedure is not allowed. Randomized subjects will have clinical follow-up at 1 month, 6 months, 12 months and at 2, 3, 4 and 5 years following the index procedure. To assess the non-inferiority of the Orsiro stent compared to the Xience stent, BIOFLOW-V randomized subjects will be combined with historical subjects from the BIOFLOW-II and BIOFLOW-IV randomized trials employing a Bayesian approach. Only subjects who meet all clinical and angiographic eligibility criteria of the BIOFLOW-V trial will be included in the analysis.
