Brief summary
This study is an Investigator initiated, randomized, multicenter, double-blind, placebo-control study. The aim of this study is to evaluate the safety and efficiency of Sirolimus for primaty antiphospholipid syndrome patients at week 24 and week 48.
Interventions
Subjects will receive Sirolimus 1.5mg/d for 48 weeks in addition to their ongoing APS treatment regimen
Subjects will receive Placebo 1.5mg/d for first 24 weeks and Sirolimus 1.5mg/d for next 24 weeks in addition to their ongoing APS treatment regimen
