About Obexelimab
Obexelimab is a bifunctional monoclonal antibody designed to bind both CD19 and FcγRIIb to inhibit B-lineage cell activity. Obexelimab has demonstrated clinical activity and was well-tolerated in five clinical trials, including in several autoimmune diseases, in which 198 subjects were dosed. In these clinical studies, obexelimab demonstrated inhibition of B cell function without depleting the cells, resulting in encouraging treatment effect in patients with various autoimmune diseases. Zenas acquired exclusive worldwide rights to obexelimab from Xencor, Inc.
