Study of Oral Rapamycin Plus Bare Metal Stents vs Drug Eltuting Stents

Phase 4 Study of Randomized Comparison Among Oral Rapamycin Plus Bare Metal Stents Versus Drug Eluting Stents in de Novo Coronary Lesions.

In a previous randomized comparison oral sirolimus plus bare metal stent compared to bare metal stent implantation alone demonstrated at one year of follow up a significant reduction of angiographic and clinical parameters of restenosis (ANMAT resolution number 3366 from June 2004 and Rodriguez A et al JACC,2006,47,1522-1529). In addition previous reported registries from our group with Drug Eluting Stents showed similar amount of reduction in clinical parameters (not angiographic)of restenosis (ERACI III, Rodriguez A et al EuroIntervention 2006,2:53-60). Taking in account that 8.3% of patients treated with oral rapamycin plus Bare Metal Stents(ORAR II Trial JACC 2006)and 8.8% of patients treated with DES developed clinical restenosis (ERACI III Registry, EuroIntervention 2006) the investigators sought to compare differences in overall cost with both revascularization strategies at 1, 2, 3 and 5 years of follow up assuming that safety and efficacy clinical end points would be similar.

Patients with de novo lesions treated in different Institutions in Buenos Aires Argentina were randomized to treat with oral sirolimus plus bare metal stent implantation (100 patients) or DES(100 patients).
