Study summary

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

Read the detailed description

Two studies demonstrated that out-of-hospital low-molecular-weight heparin given by twice daily subcutaneous injection without laboratory monitoring was as effective and as safe as continuous intravenous heparin given in-hospital. Innohep (tinzaparin) has been shown to be safe and effective for both the initial and long-term treatment of DVT. The Home LITE study compares long-term Innohep treatment to treatment with a combination of initial low-molecular-weight heparin followed by standard long-term warfarin therapy.

  • Known allergy to heparin, warfarin sodium, or bisulfites
  • History of heparin-associated thrombocytopenia
  • Severe malignant hypertension
  • Hepatic encephalopathy

What researchers measure

Primary outcomes

  1. objectively documented recurrent venous thromboembolism during initial treatment or during the 12 week follow-up period

  2. death during initial treatment or during the 12 week follow-up period

  3. safety endpoint for assessing harm was the occurrence of bleeding (all, major or minor) during the 12 week treatment interval

Secondary outcomes

  1. recurrent venous thromboembolism at 12 months

  2. death at 12 months
