Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Rosuvastatin

Arm Description

Subjects will receive 20 mg daily dose of rosuvastatin for at least 3 months

Outcomes

Primary Outcome Measures

Post-thrombotic syndrome
Incidence of post-thrombotic syndrome as measured by the Villalta Scale (score = or > 4). Minimum score=0, Maximum score=33, and a higher score indicates worse outcome.

5. Study Description

Brief Summary
The goal of this study is to determine the safety and tolerability or efficacy of adjunctive treatments (including rosuvastatin 20 mg daily) in combination with standard anticoagulation therapy (Factor Xa inhibitors) in patients with lower extremity deep vein thrombosis (DVT). The efficacy of adjunctive treatments to prevent the development of post thrombotic syndrome (PTS) after DVT will be evaluated.
Detailed Description
Post-thrombotic syndrome (PTS) is a significant complication that occurs up to 75% of patients after DVT. Rosuvastatin is a HMGCoA reductase inhibitor that has anti-inflammatory effects. In this study, the investigators will evaluate the safety and tolerability of combination standard anticoagulation therapy (e.g. Factor Xa inhibitor, rivaroxaban, apixaban) and three months of 20 mg dose of rivaroxaban and its efficacy as prophylaxis against PTS after lower extremity DVT. After the diagnosis of lower extremity DVT with either duplex venous ultrasound or other imaging, study participants will initiate standard rivaroxaban therapy as per standard medical care. All consented participants in this trial will receive three months of rosuvastatin (20 mg daily dose). Assessment of post thrombotic syndrome follow up will continue for 365 days from the time of DVT diagnosis or until resolution or stabilization of any clinically significant drug related adverse event, after which they will be considered off-study.

Primary Purpose
Prevention
Study Phase
Phase 1, Phase 2
Interventional Study Model
Single Group Assignment
Model Description
This is a prospective, single arm Phase 1/Phase 2 study of patients with lower extremity DVT. Phase 1 will assess safety and tolerability of xisomab 3G3 in patients with lower extremity DVT on standard rivaroxaban therapy in 12-18 subjects. Three doses of xisomab 3G3 (42, 126, or 252 mg IV) will be tested to determine the maximum tolerated dose (MTD) with the dose limiting toxicity as any major bleeding or serious adverse event. Phase 2 will assess the efficacy of xisomab 3G3 for the prevention of PTS and compare the 1 year incidence of PTS as determined by the Villalta score in patients with lower extremity DVT on standard rivaroxaban therapy in 30 study participants.
