Tinzaparin Lead-In to Prevent the Post-Thrombotic Syndrome — TILE  

Deep Vein Thrombosis Clinical Trial

Official title:
Tinzaparin Lead-In to Prevent the Post-Thrombotic Syndrome Phase IV Pilot Study

Clinical Trial Summary

The TILE pilot study will be a multicenter, open-label, assessor-blinded RCT (randomized control trial) comparing extended LMWH (Low Molecular Weight Heparin) vs. DOAC (Direct Oral Anticoagulants) to PTS (prevent post thrombotic syndrome) in patients with DVT (Deep Vein Thrombosis).

Clinical Trial Description

The TILE pilot study will investigate the magnitude of difference in effectiveness between LMWH (low molecular weight heparin, tinzaparin) plus DOAC (Direct Oral Anticoagulants, rivaroxaban) vs. DOAC alone to determine the sample size and assess feasibility for a larger study assessing the effectiveness of an initial 3-week lead-in course of LMWH (tinzaparin) compared to DOAC alone (rivaroxaban) in patients with proximal DVT (Deep Vein Thrombosis) at high risk of developing PTS (Post-Thrombotic Syndrome). PTS is a frequent, costly and burdensome complication of DVT, especially for patients with iliac or femoral vein DVT who have a high risk of developing PTS and severe PTS. Anticoagulant therapy appears to influence this risk, with a higher frequency of PTS in patients with DVT who receive suboptimal treatment with a VKA (Vitamin K Antagonist). DOAC are expected to avoid this and other limitations of VKA therapy and have become the standard of care for patients with DVT. Extended treatment of DVT with LMWH, by providing more effective anticoagulation and by reducing inflammation, appears to restore venous patency and reduce venous reflux compared to VKA and probably to DOAC. Extended treatment of DVT with LMWH, therefore, has the potential to reduce PTS. ;
