Fondaparinux in Critically Ill Patients With Renal Failure

Venous Thromboembolism Clinical Trial

Official title: Use of Fondaparinux in Critically Ill Patients With Renal Failure

Status Completed

Clinical Trial Summary

The primary objective of this study is to determine whether a dose-adjusted prophylaxis fondaparinux regimen of 2.5 milligrams (mg) subcutaneously administered every (q) 48 hours (hr) in patients with renal failure achieves peak and trough levels similar to patients with normal renal function, and protects patients from developing venous thromboembolism (VTE). Our hypothesis is that a dose-adjusted fondaparinux regimen, which extends the dosing interval from q24 to q48 hr, in patients with estimated creatinine clearance of < 30 ml/min, will be safe and effective.

Clinical Trial Description

We will be studying fondaparinux 2.5 mg subcutaneously every 48 hr in three distinct patient groups: 1) Acute kidney failure without hemodialysis, 2) Acute kidney failure (AKI) with intermittent hemodialysis (IHD) and 3) Acute renal failure with continuous renal replacement therapy (CRRT). All patients will be assessed for efficacy of the dose. Efficacy will be assessed by following clinically for any evidence of VTE, either deep venous thrombosis (DVT) or pulmonary embolism. In addition, lower extremity duplex studies will be performed at baseline and at the end of the study period to assess for DVT.

Secondary objectives will be safety and accumulation. Safety will be determined by assessment of clinically significant bleeding, defined as a drop in Hgb of > 2 grams (gm) in 24 hr, or the need for red blood cell transfusion related to bleeding. Accumulation may occur in renal failure and will be studied throughout the intensive care unit (ICU) stay through reevaluation of levels over time. ;
