3. The safety and efficacy of the XIENCE V EES have been demonstrated in the SPIRIT FIRST, SPIRIT II, and SPIRIT III randomized trials The safety and efficacy of the XIENCE V EES have been demonstrated in the SPIRIT FIRST, SPIRIT II, and SPIRIT III randomized trials However, these trials were not powered for superiority for clinical endpoints, nor to assess low frequency event rates (death, MI, stent thrombosis) However, these trials were not powered for superiority for clinical endpoints, nor to assess low frequency event rates (death, MI, stent thrombosis) Routine angiographic follow-up may have affected the results Routine angiographic follow-up may have affected the results Whether the performance of EES is different from PES in pts with diabetes remains uncertain Whether the performance of EES is different from PES in pts with diabetes remains uncertain SPIRIT IV Background

35. In the large-scale, prospective multicenter randomized SPIRIT IV trial, the everolimus-eluting XIENCE V stent compared to the paclitaxel-eluting TAXUS Express stent at 1-year follow-up demonstrated: Primary endpoint: Significantly reduced rate of TLF Major secondary endpoints: Significantly reduced rate of TLR and noninferior rate of cardiac death or target vessel MI Other secondary endpoints: Significantly reduced rates of stent thrombosis (protocol and ARC), target vessel MI and all MI, with comparable rates of cardiac death and all-cause death Diabetic subgroup: Comparable rate of TLF in pts with diabetes, and a marked reduction in TLF in pts without diabetes Other subgroups: Consistent relative reductions in TLF independent of clinical features, vessel size, and # and length of treated lesions SPIRIT IV Conclusions

36. Clinical Implications The results with the XIENCE V stent demonstrating enhanced safety and efficacy compared to TAXUS EXPRESS in this large-scale study without routine angiographic follow-up and with 100% monitoring set a new standard for event-free survival after DES The simultaneous reduction of stent thrombosis, MI and TLR with XIENCE V demonstrates that low late loss may be achieved with DES without sacrificing safety Outcomes in pts with diabetes may still be improved, and should represent an area of focus for future development of novel drugs and enhanced stent design
