About Telitacicept Telitacicept is a novel recombinant fusion protein designed to treat autoimmune diseases through dual inhibition of BLyS (BAFF) and APRIL - two cytokines essential to B cell and plasma cell survival. This dual-target mechanism reduces autoreactive B cells and autoantibody production, key drivers of autoimmune pathology. Telitacicept is approved in China for systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), generalized myasthenia gravis (gMG), IgA nephropathy (IgAN), and Sjögren’s disease (SjD). Vor Bio is advancing global development programs across major autoimmune indications, including a global Phase 3 trial in gMG and SjD, to support potential regulatory approvals in the United States, Europe, and Japan. About Vor Bio Vor Bio is a clinical-stage biotechnology company transforming the treatment of autoimmune diseases.
