This is a randomized trial to compare intermittent compression devices with or without post-operative Arixtra (fondaparinux sodium) in women undergoing major abdominal surgery for known or presumed gynecologic malignancies. This trial seeks to determine if there is a difference in the rate of deep venous thrombosis between these two groups.

Condition Intervention Phase
Venous Thrombosis
Drug: Fondaparinux sodium
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Prevention
Official Title: Extended Deep Venous Thrombosis Prophylaxis in Gynecologic Oncology Surgery With Intermittent Compression Devices (ICD) With or Without Postoperative Arixtra: A Randomized Controlled Trial

Further study details as provided by University of Alabama at Birmingham:

Primary Outcome Measures:
  • Comparison of Deep Venous Thromboembolism (DVT) Using Intermittent Compression Devices With and Without Arixtra [ Time Frame: 21 days ]
    Deep venous thromboembolism (DVT) rates are determined from lower extremity doppler ultrasound measurements.

Secondary Outcome Measures:
  • Incidence of Untoward Effects With Arixtra [ Time Frame: 21 days ]
    Adverse events will be evaluated to determine untoward effects.

Enrollment: 7
Study Start Date: April 2007
Study Completion Date: June 2010
Primary Completion Date: June 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: Intermittent compression devices (ICD)
All patients will receive intermittent compression devices (ICD's) during the patient's entire hospitalization after the operative procedure. Patients randomized to the standard of care management will receive ICD's only. This represents the current standard of care at our institution at the time of initiation of the trial.
Experimental: Arixtra
Patients randomized to treatment arm will initiate Arixtra treatment on post-operative day 1 and continue treatment until post-operative day 22 (21 consecutive days). Subjects randomized to this arm are to receive the standard prophylactic dose for major abdominal surgery of 2.5 mg/day for a total of 21 consecutive days (including hospitalization time and after hospital discharge).
Drug: Fondaparinux sodium
Treatment will consist of daily injections of pharmacy prepared syringes of fondaparinux sodium 2.5mg. Treatment will continue for 21 consecutive days to end on post-operative day 22.
Other Name: Arixtra

Detailed Description:
To assess the effectiveness of Arixtra in the prophylaxis of deep venous thromboembolism in gynecologic oncology patients undergoing abdominopelvic surgery.

Ages Eligible for Study:   19 Years to 85 Years   (Adult, Senior)
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • All patients undergoing open laparotomy (non-laparoscopic) gynecologic surgery.
  • Patients must be competent to self-administer injections, or must have caregivers or nurses who can perform injections
  • Patients must have signed an approved informed consent

Exclusion Criteria:

  • Patients with medical history which requires chronic anticoagulation (i.e. previous DVT, pulmonary embolism, atrial fibrillation, heart valve replacement)
  • Patients with contraindications to anticoagulation (generalized bleeding disorders, peptic ulcer disease, hemorrhagic stroke, etc)
  • Contraindications to placement of ICDs (history of lower extremity venous stasis ulcers)
  • Patients receiving low molecular weight heparin or unfractionated heparin for prophylaxis post-operatively
  • Patients who are unable to receive injections as an outpatient and/or unable to undergo a doppler ultrasound of the lower extremities
  • Renal insufficiency (creatinine clearance < 30 mL/min)
  • Patients who have a body weight < 50 kg
  • Hypersensitivity to low molecular weight heparin
  • Patients who are pregnant or have a positive pregnancy test.
  • Patients receiving continuous (indwelling) epidural.
