About XOMA Corporation

XOMA combines a portfolio of innovative therapeutic antibodies, both in late-stage clinical development and in preclinical research, with its recently launched commercial operations. XOMA focuses its antibody research and development on allosteric modulation, which offers opportunities for new classes of therapeutic antibodies to treat a wide range of human diseases. XOMA is developing its lead product gevokizumab (IL-1 beta modulating antibody) with Les Laboratoires Servier (Servier) through a global Phase 3 program in non-infectious uveitis and 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 preclinical antibodies, including Selective Insulin Receptor Modulators (SIRMs) that could have a major effect on the treatment of diabetes. In order to retain significant value from its scientific discoveries, XOMA initiated commercial operations in January 2012 through the licensing of U.S. commercial rights to Servier's ACEON^® (perindopril erbumine) and a patent-protected portfolio of product candidates.
