Trial of the Effect of Low-Molecular-Weight Heparin (LMWH) Versus Warfarin on Mortality in the Long-Term Treatment of Proximal Deep Vein Thrombosis (DVT) (Main LITE Study)

Summary

The purpose of this study is to assess the long-term treatment of patients with proximal venous thrombosis through the administration of subcutaneous low-molecular-weight heparin (tinzaparin sodium) versus the standard care use of intravenous heparin followed by oral warfarin sodium.
