Study summary

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.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 24, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
