About ZBIO
Zenas BioPharma, Inc. is a clinical-stage global biopharmaceutical company focused on the development and commercialization of transformative therapies for patients with autoimmune diseases. The Company's lead product candidate, obexelimab, is a bifunctional monoclonal antibody designed to bind both CD19 and FcyRIIb, which are broadly present across B cell lineage, to inhibit the activity of cells that are implicated in many autoimmune diseases without depleting them. The Company is developing obexelimab as a potential immunology and inflammation (I&I) franchise for patients in several autoimmune diseases. The first three indications it is pursuing include immunoglobulin G4-related disease (IgG4-RD), relapsing multiple sclerosis (RMS) and systemic lupus erythematosus (SLE). Its other programs include ZB002 (an anti-TNFα monoclonal antibody), ZB004 (a CTLA-4-Ig fusion), and ZB001 and related programs. ZB002 is a recombinant human monoclonal antibody directed at human TNFα.
