Clinical Trial Summary

The standard or usual treatment for patients diagnosed with deep vein thrombosis or pulmonary embolism is treatment with blood thinners (called anticoagulants). While treatment of blood clots with blood thinners is effective, some research has shown that adding a statin (medication used to lower cholesterol) may give extra protection. It is thought that statins can improve how cells along the walls of the vein control inflammation, which can prevent new blood clots from forming. The medication in this study, rosuvastatin, is approved in Canada for use as a cholesterol-lowering medication. The use of rosuvastatin in this study is considered investigational. This means that Health Canada has not approved the use of rosuvastatin as a treatment for blood clots. However, it has been approved for use in this research study. The purpose of this study is to examine if adding a statin (rosuvastatin) to the usual blood thinner treatment will decrease the risk of another blood clot forming. The investigators also hope to discover if taking a statin reduces damage to your veins. To do this, some of the participants in this study will get rosuvastatin and others will receive a placebo (a substance that looks like the study rosuvastatin but does not have any active or medicinal ingredients). The placebo in this study is not intended to have any effect on your blood clot. A placebo is used to make the results of the study more reliable.


Clinical Trial Description

Recent research has demonstrated that it is plausible that statins have additive, and potentially even synergistic effects, in reducing recurrent VTE in patients managed with anticoagulant-based strategies. Furthermore, it is plausible that statins may reduce the risk of recurrent VTE in those not on anticoagulants and therefore offer an alternative in patients with contraindications to anticoagulants (e.g. after major intracranial bleed), who refuse to take anticoagulants long-term (e.g. due to lifestyle modifications or fear of bleeding) or who cannot afford anticoagulants (e.g. vulnerable or impoverished populations). Finally, statins may also provide protection from recurrent VTE in patients who are not fully compliant with anticoagulant therapy. However, no known RCTs have been done to explore these possibilities. This study aims to determine if generic rosuvastatin reduces the risk of recurrent VTE compared to placebo in patients with symptomatic major VTE. Primary Objectives - To determine the primary outcome event rate (i.e. symptomatic recurrent major VTE [proximal DVT or segmental or larger PE]) in patients taking generic rosuvastatin compared to placebo. Secondary Objectives - To determine the major bleeding event rate in patients taking generic rosuvastatin compared to placebo. - To explore if rosuvastatin reduces the incidence of PTS, as measured by the Villalta scale at end of study. ;
