Randomized Clinical Trial Comparing Orsiro1 Drug-Eluting Stent with Xience2 DES
- In this 1,334 patient large, international, randomized trial Orsiro demonstrated statistically significantly lower Target Lesion Failure (TLF) rates compared to Xience at 12 months (Orsiro 6.2%, Xience 9.6%, p-value = 0.04)
- Procedure success was significantly higher with Orsiro (Orsiro 93.8%, Xience 90.1%, p-value = 0.02), mainly driven by a higher rate of in-hospital Myocardial Infarction (MI) associated with Xience (Orsiro 3.9%, Xience 6.7%, p-value = 0.03)
- Stent Thrombosis (ST) rate was numerically lower in the Orsiro cohort (Orsiro 0.5%, Xience 1.2%, p-value = 0.18)
TLF at 12 months defined as a composite of Cardiac Death (CD), Target-Vessel MI (TV-MI) or any clinically-driven Target Lesion Revascularization (cd-TLR)
Pre-specified secondary endpoints:
- Components of the primary endpoint
- Target Vessel Failure (TVF) and individual TVF components
- MI and/or CD
- ST (all, definite, definite/probable, probable, possible ST)3
- Success rates (device, lesion and procedure)
