Condition(s) targeted: Embolism

Acutely ill immobilized patients are at a high risk for thromboembolic events including deep venous thrombosis or pulmonary embolism. Unfractionated heparin (UFH) and low molecular weight heparins (LMWH) are thought to be effective in preventing thromboembolic events. This study is designed to provide efficacy and safety data for thromboprophylaxis with the LMWH certoparin in comparison to thromboprophylaxis with UFH in acutely ill non-surgical patients.

Clinical Details

Official title: An Open-label Comparison of the Efficacy and Safety of the Low-molecular-weight Heparin (3000 U Anti-Xa Once Daily) With Unfractionated Heparin for the Prevention of Thromboembolic Complications in Acutely Ill Non-surgical Patients

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Prevention

Primary outcome: The occurrence of thromboembolic events (proximal or distal DVT, PE or VTE related death) during treatment

Secondary outcome:

Thromboembolic events during follow-up period of 3 months

Safety endpoints occurring during the treatment period: Hemorrhage (major or minor), Thrombocytopenia, Symptomatic HIT type II, Induction of HIT-II specific antibodies


Minimum age: 40 Years. Maximum age: N/A. Gender(s): Both.
