Study Summary

This is a single-arm pilot study in Peking Union Medical College Hospital. Telitacicept will be added on traditional antithrombotic and immunosuppressive treatment in primary antiphospholipid syndrome (APS) patients with three positive antiphospholipid antibodies (aPL) and at least one extra-criteria manifestations, including thrombocytopenia, autoimmune hemolytic anemia, aPL associated nephropathy, heart valvular disease, non-stroke neurological manifestations. This study aims to evaluate the efficacy of Telitacicept in preventing thrombosis and improving extra-criteria manifestations on high-risk APS patients.

  • with at least one extra-criteria manifestations of APS, including thrombocytopenia,hemolytic anemia, aPL nephropathy, valve heart disease and neurologicalmanifestations.
