Trial overview
Official title: A Multicentre, Randomized, Open-label Study to Evaluate the Efficacy andSafety of Fondaparinux versus Low Molecular Weight Heparin(Nadroparin) in Patients Requiring Rigid or Semi-rigid Immobilization for at least 21 Days and up to 45 Days because of Isolated Non-surgical Below-Knee Injury
Trial description: The purpose of this study is to evaluate the efficacy and safety of fondaparinux in comparison with a heparin (nadroparin) in preventing deep vein thrombosis (blood clots in the leg veins), whether symptomatic or detected by ultrasound, and pulmonary embolism (blood clots that migrate to the lungs) in patients with leg injuries below the knee that require a cast or other type of immobilization but not surgery.
Primary purpose:
Prevention
Trial design:
Parallel Assignment
Masking:
None (Open Label)
Allocation:
Randomized
Primary outcomes:
Number of participants with venous thromboembolism (VTE) or death up to the time of complete mobilization
Timeframe: Day 1 to complete mobilization plus 2 days (average of 35.9 study days)
Secondary outcomes:
Number of participants with any adjudicated components of VTE, asymptomatic DVT, symptomatic DVT, symptomatic PE, and death
Timeframe: Day 1 to complete mobilization plus 2 days (average of 35.7 study days)
Number of participants with confirmed VTE and death up to the final visit or contact
Timeframe: Day 1 to 5 weeks (plus or minus 1 week) after complete mobilization (average of 67.8 study days)
Number of participants with major bleeding from Day 1 to complete mobilization and from Day 1 up to the final visit or contact
Timeframe: Day 1 to complete mobilization plus 4 days (average of 37.7 study days); Day 1 up to final visit or contact (average of 66.3 study days)
Number of participants with clinically relevant non-major bleeding from Day 1 to complete mobilization and from Day 1 up to the final visit or contact
Timeframe: Day 1 to complete mobilization plus 4 days (average of 37.7 study days); Day 1 up to final visit or contact (average of 66.3 study days)
Number of participants with minor bleeding from Day 1 to complete mobilization and from Day 1 up to the final visit or contact
Timeframe: Day 1 to complete mobilization plus 4 days (average of 37.7 study days); Day 1 up to final visit or contact (average of 66.3 study days)
Participants with any incidence of any bleeding event as adjudicated by a CAC) from Day 1 to complete mobilization and from Day 1 up to the final visit or contact
Timeframe: Day 1 to complete mobilization plus 4 days (average of 37.7 study days); Day 1 up to final visit or contact (average of 66.3 study days)

Inclusion and exclusion criteria
Inclusion criteria:
- Requiring rigid or semi-rigid immobilization (e.g. with a plaster cast or brace) for at least 21 days and up to 45 days because of isolated non-surgical below-knee injury
- With a no weight-bearing recommendation at the time of inclusion (partial weight bearing is permitted e.g. crutches, walking cast, relief shoes),
- Presenting at least one of the following risk factors for venous thromboembolism: below-knee fracture or Achilles tendon rupture, age ≥40 years, body mass index > 30 kg/m2, oestrogen-containing hormonal replacement therapy or oral contraception, active cancer (treatment ongoing or stopped for less than one year), history of VTE, congenital or acquired hypercoagulable state,

- Able and willing to provide written informed consent
Exclusion criteria:
- Delay between injury and randomization greater than two days,
- Treatment with antithrombotic or anticoagulant therapy, including low-dose anticoagulation, for more than 2 days prior to randomization,
- Anticoagulant therapy required or likely to be required during the study period for another reason (e.g. planned surgery justifying pharmacological thromboprophylaxis, curative dose for treatment of VTE, etc.)
