Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults who have been diagnosed with symptomatic proximal leg deep vein thrombosis or pulmonary embolism within the last 30 days.

Probably not a fit

Patients currently prescribed a statin or those with contraindications to rosuvastatin will not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial investigates the effectiveness of rosuvastatin, a cholesterol-lowering medication, in reducing the risk of recurrent venous thromboembolism (VTE) in patients who have recently experienced a major VTE event. Participants will be randomly assigned to receive either rosuvastatin or a placebo in addition to standard anticoagulant therapy. The study aims to determine if the addition of rosuvastatin can lower the incidence of symptomatic recurrent major VTE and assess its impact on post-thrombotic syndrome. The trial will also monitor for any major bleeding events associated with the treatment.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option to reduce the risk of recurrent blood clots for patients with venous thromboembolism.

How similar studies have gone: While the use of statins in this context is novel, previous studies have suggested potential benefits, but no randomized controlled trials have been conducted to confirm these findings.
