Frequency of Non-Cr Cl Dose Adjusted Infusion Among Patients with Reduced Renal Function in PROTECT HSC Symposium ACC 2005 P=0.51 N=35 N=32 Per the protocol, the infusion dose was to be reduced for patients with CrCl50 ml/min (Eptifibatide) or CrCl<60 ml/min (Bivalirudin) Kirtane, Murphy, and Gibson
Relation of Dose Adjustment of Eptifibatide Infusion to Bleeding Outcomes HSC Symposium ACC 2005 Major/Minor Bleeding Transfusion P=0.028 P=0.009 CrCl>50 CrCl50 CrCl50 CrCl>50 % Transfusion % Major / Minor Bleeding N=17 N=18 N=530 N=17 N=18 N=530 No bleeding events or transfusions occurred among patients with CrCl50 ml/min who received a reduced-dose infusion Kirtane, Murphy, and Gibson
Bleeding in PROTECT HSC Symposium ACC 2005 • Half the bleeds occurred after 6 hours of infusion • Increasing age and a failure to dose-adjust the eptifibatide infusion in patients with reduced Creatinine Clearance (CrCl) 50 mg/dL (not Cr or weight) were the strongest independent correlates of bleeding events • A failure to adjust the eptifibatide dose for CrCl rather than Cr occurred in 17/35 (48.5%) of patients with reduced CrCl, and this was associated with a five-fold greater incidence of bleeding events (17.7% vs. 2.7%, p=0.014)
