Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate the safety and efficacy of a single administration of TB-402 for the prevention of VTE in patients undergoing knee replacement surgery.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Currently available anticoagulant therapies for the prevention of VTE include low molecular weight heparins, pentasaccharides and vitamin K antagonists, all of which have inherent limitations(1-3).

Improved anticoagulant agents are therefore required(4). A novel antithrombotic agent requires demonstration of both efficacy and safety in relevant populations. Phase II studies are frequently performed in patients undergoing total hip replacement and/or total knee replacement because of the high and well documented incidence of deep vein thrombosis in the absence of adequate thromboprophylaxis(5-7).

In this study, we assess the safety and efficacy of TB-402, a novel antithrombotic agent that partially inhibits factor VIII, in the prevention of VTE in patients undergoing total knee replacement surgery.
