Details and patient eligibility

About

Design: prospective, randomized, multi-center trial comparing the safety and efficacy in the prevention of target lesion failure (TLF) of second generation paclitaxel- versus ABT578- versus Everolimus- eluting stents Study Population: all consecutive diabetic patients with de novo coronary artery lesions undergoing drug-eluting stent implantation in 2010-12.

Time Course: initial Enrollment: October 2010; end of the Enrollment: December 2012 Primary End-Point: target lesion revascularization (TLF) defined as the occurrence of cardiac death, myocardial infarction and repeated lesion revascularization within 12 months.

Secondary End-Points: 1) impact of glucose level during the first three months following the procedure (assessed by hemoglobin A1C ) on clinically-driven target lesion revascularization; 2)TLF and TLR within 12, 24 and 36 months; 3) comparison 12 months versus prolonged (> 12 months) of dual antiplatelet therapy

Full description

Prospective, randomized, triple arm study. The study population will include all consecutive diabetic patients within 24 months undergoing elective second generation DES implantation for de novo coronary artery disease. In the randomization process all participating centers will be equally stratified to avoid statistical unbalance.

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

3. Subject and the treating physician agree that the subject will comply with all follow-up evaluations
4. Subject has been informed of the nature of the study and agrees to its provisions and has provided written informed consent as approved by the Institutional Review Board/Ethics Committee of the respective clinical site

Exclusion criteria

1. Subject's age is < 18 years and with acute myocardial infarction in the 48 prior to the procedure
2. The patient is pregnant or breastfeeding
3. Known allergies to: aspirin, clopidogrel (Plavix) and ticlopidine (tiklid), heparin, Paclitaxel, Everolimus, ABT 578, stainless steel, or contrast agent (which cannot be adequately pre-medicated)
4. A platelet count < 75,000 cells/mm3 or > 700,000 cells/mm3 or a WBC < 3,000 cells/mm3

9. Any lesion that is located in a saphenous vein graft
10. In the investigator's opinion, subject has a co-morbid condition(s) that could limit the life expectancy to less than one year, or limit the subject's ability to participate in the study or comply with follow-up requirements or impact the scientific integrity of the study
