ISAR-SWEET Trial Is Abciximab a Superior Way to Eliminate Elevated Thrombotic Risk in Diabetics Presented at American Heart Association Scientific Sessions 2004 Presented by Dr. Julinda Mehilli
ISAR-SWEET Trial 701 diabetic patients scheduled to undergo elective PCI in a native coronary vessel and pre-treated with clopidogrel 600 mg for >2 hours prior to the procedure Randomized, blinded • Abciximab • Glycoprotein IIb/IIIa inhibitor • n=351 • 0.25 mg/kg bolus • 0.125 μg/kg/min infusion for 12 hours • Placebo • n=350 • Endpoint (12 months): Composite of all-cause mortality or myocardial infarction Presented at AHA Scientific Sessions 2004
ISAR-SWEET Trial Primary Composite Endpoint at 12 months p=0.91 Insulin-dependent Diabetes Subgroup Primary Composite Endpoint at 12 months p=0.66 % • Baseline characteristics were well balanced in the treatment groups. 29% of the abciximab arm and 28% of the placebo arm were insulin-dependent. • There was no difference in the primary endpoint of death or MI at 12 months. • There was also no significant difference in death or MI at 12 months in the subgroup of patients presenting with insulin-dependent diabetes. Presented at AHA Scientific Sessions 2004
ISAR-SWEET Trial Secondary Endpoint: Binary Restenosis p=0.01 Secondary Endpoint: Target Lesion Revascularization p=0.03 % • The secondary endpoint of binary restenosis at angiographic follow-up was lower in the abciximab group. Additionally, target lesion revascularization was lower in the abciximab group. Presented at AHA Scientific Sessions 2004
ISAR-SWEET Trial Major Bleeding p=NS Transfusions p=0.11 Minor Bleeding p=0.09 % • There was no difference in major bleeding between the treatment groups, but both minor bleeding and transfusions trended higher in the abciximab group. Presented at AHA Scientific Sessions 2004
ISAR-SWEET Trial • Among diabetic patients undergoing elective PCI and pretreated with high-dose clopidogrel, treatment with abciximab was not associated with a difference in the primary endpoint of death or MI at 12 months compared with placebo, but was associated with a lower rate of binary restenosis and target lesion revascularization. • These data are similar to the ISAR REACT trial, which showed no difference in 30 day major cardiac events with abciximab compared with placebo in low-risk patients undergoing PCI who were pretreated with 600 mg clopidogrel. • While there was no difference in the primary endpoint of death or MI in the present trial, it should be noted that the trial was powered to detect a 50% reduction with abciximab, a relatively large improvement in clinical events that may have been over-estimated. Only 10% of patients in the trial were treated with a drug-eluting stent.
