The purpose of this study is to determine a preventative dose of study drug, Arixtra® for patients with kidney disease. We will measure the blood levels of Arixtra® in patients with kidney disease and develop guidelines for dosing.

Condition Intervention Phase
Renal Insufficiency Drug: fondaparinux sodium injection Phase 1

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Pharmacokinetic Study of Fondaparinux in Inpatients With Renal Dysfunction

Further study details as provided by Duke University:

Primary Outcome Measures:
  • Blood samples to measure specific Arixtra® concentration [ Time Frame: • Three blood samples for PK analyses will be obtained within the 24 hour period immediately following either the third or fourth consecutive dose of Arixtra ]
    peak level will be collected 2-3 hours after the dose interval level will be collected between peak and midpoint midpoint level will be collected 12 hours after the dose interval level will be collected midpoint and trough trough level will be collected just prior to the next scheduled dose

Secondary Outcome Measures:
  • Frequency of bleeding events and new thrombotic events [ Time Frame: Daily assessments will be made for bleeding and thrombosis ]
    events will be used to compare to rates in patients without renal dysfunction

Enrollment: 9
Study Start Date: May 2010
Study Completion Date: February 2013
Primary Completion Date: October 2012 (Final data collection date for primary outcome measure)
