Brief 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.

Arm Intervention/treatment
Experimental: Rosuvastatin
Participants randomized to the experimental arm will take one rosuvastatin 20 mg tablet by mouth every day for the duration of their participation in the study.
Drug: Rosuvastatin Calcium
Each participant will receive the usual treatment for their newly diagnosed blood clot in addition to the intervention they are randomized to.
Other Name: Rosuvastatin

Placebo Comparator: Placebo
Participants randomized to the control arm will take one placebo tablet by mouth every day for the duration of their participation in the study.
Drug: Placebo Oral Tablet
Each participant will receive the usual treatment for their newly diagnosed blood clot in addition to the intervention they are randomized to.
Other Name: Placebo




Primary Outcome Measures :
  1. Recurrent Major VTE [ Time Frame: Up to 60 months ]
    Symptomatic recurrent major VTE (proximal DVT or segmental or larger PE) occurring between randomization and the end of follow-up (i.e. completion of the trial) in patients taking generic rosuvastatin as compared with placebo.


Secondary Outcome Measures :
  1. Post Thrombotic Syndrome [ Time Frame: Up to 60 months ]

    Post-thrombotic syndrome as measured by the Villalta scale throughout the follow-up period in patients taking generic rosuvastatin as compared with placebo. The Villalta PTS scale has been adopted by the International Society on Thrombosis and Haemostasis (ISTH) as a standard to diagnose and grade the severity of PTS in clinical studies.

    Points are summed to yield total score: 0-4: No PTS; 5-9: Mild PTS; 10-14: Moderate PTS; 15 or more, or presence of ulcer: Severe PTS.


  2. Number of participants diagnosed with non-major VTE during follow-up [ Time Frame: Up to 60 months ]

    Symptomatic non-major VTE (see below) occurring between randomization and the end of follow-up (i.e. completion of the trial) in patients taking generic rosuvastatin as compared with placebo.

    Non-major VTE:

    • Distal DVT (distal to the trifurcation of the popliteal vein);
    • Isolated sub-segmental PE;
    • Upper extremity DVT;
    • Superficial phlebitis > 5 cm;
    • Superficial phlebitis ≤ 5 cm.

  3. Number of participants diagnosed with an arterial vascular event during follow-up [ Time Frame: Up to 60 months ]

    Components of composite arterial vascular events (see below) occurring between randomization and the end of follow-up (i.e. completion of the trial) in patients taking generic rosuvastatin as compared with placebo.

    Components of composite arterial vascular events:

    • Fatal myocardial infarction;
    • Non-fatal myocardial infarction;
    • Hospitalization for unstable angina;
    • Coronary artery revascularization;
    • Sudden cardiac death;
    • Ischemic stroke.

  4. Number of deaths during study participation [ Time Frame: Up to 60 months ]
    All-cause mortality occurring between randomization and the end of follow-up (i.e. completion of the trial) in patients taking generic rosuvastatin as compared with placebo.


Other Outcome Measures:
  1. Number of participants who have a bleeding event during follow-up [ Time Frame: Up to 60 months ]
    Bleeding event (major, clinically relevant non-major, minor) occurring between randomization and the end of follow-up (i.e. completion of the trial) in patients taking generic rosuvastatin as compared with placebo.
