Outcome Measures
Primary Outcomes (1)
Number of Participants With an Acute Thrombosis Event
To determine the efficacy of Hydroxychloroquine in the primary thrombosis prevention of persistently aPL-positive but thrombosis free patients with no other systemic autoimmune diseases over the five year study period.
2 years
Study Arms (2)
Standard treatment
NO INTERVENTIONpatients randomized to standard treatment will not receive hydroxychloroquine.
Hydroxychloroquine
EXPERIMENTALPatients will be randomized to receive standard of care or standard of care + hydroxychloroquine. Dose will be weight-adjusted: 200 mg daily for patients weighing \<60kg; and 400 mg daily (200 mg twice a day)for patients weighing \>60kg.
