About XOMA Corporation

XOMA's portfolio of innovative product candidates is the result of the company's focus on allosteric modulation, which offers opportunities to develop new classes of therapeutic antibodies with the potential to treat a wide range of human diseases. XOMA is developing its lead product gevokizumab (IL-1 beta modulating antibody) with SERVIER through a global Phase 3 program in Behçet's disease uveitis and non-infectious uveitis as well as ongoing proof-of-concept studies in other IL-1-mediated diseases. XOMA's scientific research also produced the XMet program, which consists of three classes of antibodies, including XOMA 358, an allosteric monoclonal antibody that reduces both the binding of insulin to its receptor and downstream insulin signaling, that could have a major effect on the treatment of abnormal metabolic states.
