The purpose of this study is to determine whether a drug named Fluvastatin is beneficial and safe in reducing the risk of cardiovascular disease and blood clots in patients with antiphospholipid antibodies or Antiphospholipid Syndrome (APS).

The primary objective of the study is to determine the effects of fluvastatin on pro-thrombotic and pro-inflammatory markers in aPL-positive lupus and non-lupus patients (primary endpoint) and to determine the safety of fluvastatin in aPL-positive lupus and non-lupus patients (secondary endpoint).

All eligible patients will sign an IRB-approved consent form during the screening visit and give blood for baseline laboratory tests. Within a week of the screening visit, all patients will be started on Fluvastatin 40 mg daily for three months. At three months patients will be instructed to stop the study medication and they will be followed for another three months. Thus, the total duration of the study is six months: first three months is interventional and the last three months is observational.

Inclusion Criteria:

• Persistently antiphospholipid-antibody positive patients (positive lupus anticoagulant test, anticardiolipin antibody ≥ 40 GPL /MPL, and/or anti- β2-glycoprotein I antibody > 20 SGU/SMU) with or without systemic lupus erythematosus

An adverse event (AE) was defined as any untoward medical occurrence in a study patient regardless of causality assessment. A serious AE was defined as one occurring at any dose that met one or more of the following criteria: death; life-threatening; requiring or prolonging inpatient hospitalisation; disabling; or resulting in a congenital anomaly/birth defect.
