SESAMI Trial Sirolimus Stent vs. Bare Stent in Acute Myocardial Infarction Trial Presented at The Euro. PCR meeting Paris, France May 2006 Presented by Dr. Maurizio Menichelli

SESAMI Trial: Background • The goal of the trial was to evaluate primary/rescue percutaneous coronary intervention (PCI) using a sirolimus-eluting stent compared with a bare metal stent among patients with acute myocardial infarction. www.

SESAMI Trial: Study Design 320 patients with acute myocardial infarction to be treated with primary or rescue angioplasty without left main disease, saphenous vein grafts, and cardiogenic shock. Randomized. 19% female, mean age 61 years, follow-up 1 year Primary or rescue angioplasty with sirolimus-eluting stent n=160 Primary or rescue angioplasty with bare metal stent n=160 One year angiographic follow up n=166 g g Primary Endpoint: Angiographic binary restenosis at one year Secondary Endpoint: One year target lesion revascularization (TLR), target vessel revascularization (TVR), target lesion vessel failure (TVF) and major adverse cardiac events (MACE) www.

SESAMI Trial: Baseline Characteristics • Baseline characteristics were balanced between groups, with primary PCI

SESAMI Trial: Baseline Characteristics • Baseline characteristics were balanced between groups, with primary PCI performed in 82% of patients and rescue PCI in 18% of patients. • In approximately half of the patients, the infarct– related artery was the left anterior descending artery. • In the majority of patients, Abciximab was used in either the emergency room or the cath lab. • Post-procedural TIMI grade 3 flow was present in 95% of patients. www.

SESAMI Trial: Primary Endpoint Incidence One year binary restenosis p<0. 05 www. Clinical trial

SESAMI Trial: Primary Endpoint Incidence One year binary restenosis p<0. 05 www. Clinical trial results. org • The primary endpoint of one year binary restenosis on angiography occurred less often in the sirolimus-eluting stent group vs. the bare metal stent group (9. 3% vs. 21. 3%, relative risk reduction [RRR] 56%, p<0. 05). • Likewise, clinically driven restenosis was also lower in the sirolimus-eluting stent group (5. 6% vs. 17. 2%, RRR 64%, p<0. 05).

SESAMI Trial: Secondary Endpoints Rate Secondary Endpoints (all p<0. 05) www. Clinical trial results. org • Among the secondary endpoints, the sirolimus-eluting stent group had lower rates of TLR (4. 3% vs. 11. 2%), TVR (5% vs. 13. 1%), MACE (6. 8% vs. 16. 8%) and TVF 8. 7% vs. 18. 7). • There was no difference in acute thrombosis (0. 6%), or acute + subacute thrombosis (3. 1% vs. 3. 7%).

SESAMI Trial: Summary • Among patients with acute myocardial infarction undergoing primary or rescue

SESAMI Trial: Summary • Among patients with acute myocardial infarction undergoing primary or rescue PCI, use of sirolimus-eluting stent was associated with a reduction in binary restenosis at one year compared with use of a bare metal stent. • Results of the present single center trial are similar to those seen in the multi-center TYPHOON trial, which showed a reduction in target vessel failure at one year with sirolimus-eluting stents compared with bare metal stents in PCI for acute MI, driven primarily by a reduction in TLR. • The PASSION trial, however, did not demonstrate a reduction in TLR with paclitaxel-eluting stents over bare metal stents among STEMI patients. • A cost-effectiveness analysis from the present trial is underway. www.
