About moderate to severe acne vulgaris
Moderate to severe acne vulgaris is estimated to affect approximately three to four million people in the U.S. Acne is characterized by the presence of a bacterium known as Proprionumbacterium acne, which promotes the production of proinflammatory substances including IL-1 beta in experimental models of the disease.
Moderate to severe acne that does not respond to topical agents is often treated with orally administered antibiotics. For the most severe, non-responsive acne, isotretinoin (an oral retinoid drug) treatment may be prescribed, although it is only available through a restricted distribution program due to its side effect profile.About Gevokizumab Gevokizumab (XOMA 052) is a potent monoclonal antibody with unique allosteric modulating properties and the potential to treat patients with a wide variety of inflammatory and other diseases. Gevokizumab binds strongly to interleukin-1 beta (IL-1 beta), a pro-inflammatory cytokine that has been shown to be involved in non-infectious uveitis, including Behçet's uveitis, cardiovascular disease, and other auto-inflammatory diseases. By binding to IL-1 beta, gevokizumab inhibits the activation of the IL-1 receptor, thereby modulating the cellular signaling events that produce inflammation. Gevokizumab has been studied in over 500 patients, with approximately 300 patients on treatment for six months, and has been shown to be well-tolerated. Information about gevokizumab clinical studies can be found at www.clinicaltrials.gov . About XOMA 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 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.
