Fondaparinux in Critically Ill Patients With Renal Failure

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.

Primary Outcome Measures:
  • To Determine if an Adjusted-dose of Fondaparinux 2.5 mg Subcutaneously (SQ) q48 hr in Critically Ill Patients With Renal Failure Will Achieve Peak and Trough Levels Similar to Patients With Normal Renal Function on 2.5 mg SQ Daily Dosing of Fondaparinux. [ Time Frame: 2 years ]
    Fondaparinux Peak Levels measured at time +3 hours after the dose, and Trough Levels, measured at time + 47 hours post-dose around the first 5 doses of fondaparinux and then every 3rd dose thereafter. Levels will be sent to our hospital laboratory and performed using a calibrated fondaparinux assay.

Secondary Outcome Measures:
  • To Determine Number of Participants Who Experienced a Bleeding Event, Either Major or Minor, and to Determine the Number of Participants Who Experienced a Venous Thromboembolism During the Study Period [ Time Frame: 2 years ]
    Safety will be assessed through monitoring for clinical signs of bleeding. Major and minor bleeding will be documented. In additions, venous doppler studies of the bilateral lower extremities will be performed at study entry and study completion to monitor for any evidence of venous thromboembolism during the study period. We will report on the number of participants experiencing an adverse event during the study

Arms Assigned Interventions
Experimental: Renal failure on intermittent dialysis
These are patients with renal failure, on intermittent hemodialysis (IHD), receiving fondaparinux 2.5 mg subcutaneously every 48 hours
Drug: Fondaparinux
2.5 mg every 48 hours
Other Name: Arixtra
Experimental: Renal failure-renal replacement therapy
These are patients with renal failure, either acute or chronic, on continuous renal replacement therapy (CRRT) receiving fondaparinux 2.5 mg subcutaneously every 48 hours
Drug: Fondaparinux
2.5 mg every 48 hours
Other Name: Arixtra
Experimental: Renal failure, not on dialysis
These are patients with acute kidney injury not yet on dialysis, receiving fondaparinux 2.5 mg subcutaneously every 48 hours
Drug: Fondaparinux
2.5 mg every 48 hours
Other Name: Arixtra

Detailed 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.
