This study is designed to provide efficacy and safety data for certoparin in the prophylaxis of venous thromboembolism in immobilized, acutely ill medical patients.

Condition Intervention Phase
Drug: Certoparin
Drug: Unfractionated Heparin
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: A Randomized, Double-blind, Multi-center Comparison of the Efficacy and Safety of Certoparin (3000 U Anti-Xa o.d.) With Unfractionated Heparin (5000 IU t.i.d.) in the Prophylaxis of Thromboembolic Events in Acutely Ill Medical Patients

Primary Outcome Measures:
  • Incidence of venous thromboembolism during treatment (proximal deep vein thrombosis, pulmonary embolism, death related to venous thromboembolism) [ Time Frame: 20 days ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • proximal and distal deep vein thrombosis (DVT) (combined and separate) assessed by ultrasound screening, [ Time Frame: 20 days ] [ Designated as safety issue: No ]
  • symptomatic DVT, [ Time Frame: 20 days ] [ Designated as safety issue: No ]
  • symptomatic non-fatal pulmonary embolism (PE), [ Time Frame: 20 days ] [ Designated as safety issue: No ]
  • combination of proximal DVT, non fatal PE and death from all causes including PE [ Time Frame: 20 days ] [ Designated as safety issue: No ]
  • VTE related death, [ Time Frame: 20 days ] [ Designated as safety issue: No ]
