Pharmacokinetic Evaluation of Tirofiban Using a Single High-Dose Bolus In Subjects With Varying Degrees of Renal Function

Summary

The purpose of this study is to evaluate tirofiban concentration in the blood over a period of 24 hours after tirofiban administration. Subjects with varying degrees of renal insufficiency (i.e. kidney function) will be included in the study. Tirofiban is known to be cleared from the blood by the kidneys and so people with kidney problems clear tirofiban to a slower extent compared to people without kidney problems. By comparing the tirofiban concentration profile between subjects with healthy kidney function versus with impaired kidney function, a tirofiban dosing recommendation for subjects with impaired kidney function can be made. This is a non-randomized, single-center, open-label study. A single dose of tirofiban (25 µg/kg administered intravenously over a 3 min period) will be administered to subjects with normal renal function (\>90 mL/min CrCl), moderate (30-59 mL/min CrCl), and severe (\<30 mL/min CrCl) renal impairment with non-dialysis-dependent renal insufficiency

Detailed description

Tirofiban is cleared from the plasma largely by renal excretion. As a consequence, a dosage adjustment of 50% of the tirofiban label dosing regimen (0.4 μg/kg/min for a period of 30 minutes, followed by an infusion of 0.10 μg/kg/min) is recommended in patients with severe renal impairment (\<30 mL/min CrCl), including those who require hemodialysis. The dosage adjustment for the tirofiban high-dose bolus regimen (25 μg/kg bolus followed by a 0.15 μg/kg/min maintenance) for patients with varying degrees of renal insufficiency is however unknown. The purpose of this study is to determine the extent of dosage adjustment for the high-dose bolus regimen for patients with moderate (30-59 mL/min CrCl), and severe (\<30 mL/min CrCl) renal insufficiency. This non-randomized, single-center, open-label study evaluating the pharmacokinetic (PK), pharmacodynamic (PD), and safety profile of a single high-dose IV bolus injection of tirofiban (25 µg/kg). A single dose of tirofiban will be administered to the subjects with normal renal function (\>90 mL/min CrCl), moderate (30-59 mL/min CrCl), and severe (\<30 mL/min CrCl) renal impairment with non-dialysis-dependent renal insufficiency (NDDRI).
