Gevokizumab (XOMA 052 /S 78989) is a potent monoclonal antibody with unique allosteric modulating properties and the potential to treat patients with a wide variety of inflammatory diseases 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 Behçet's and other forms of non-infectious uveitis, cardiovascular disease, and other auto-inflammatory diseases. In binding to IL-1 beta, gevokizumab inhibits the activation of the IL-1 receptor, thereby modulating the cellular signaling events that produce inflammation.
Servier is XOMA's development and commercialization partner for gevokizumab. XOMA holds rights to gevokizumab in the U.S. and Japan for non-cardiometabolic indications, including non-infectious uveitis, acne, and erosive osteoarthritis of the hand for which clinical studies are ongoing. Information on all gevokizumab clinical studies can be found at www.clinicaltrials.gov .
Gevokizumab has been granted Orphan Drug Designation by the U.S. Food & Drug Administration (FDA) for the treatment of non-infectious intermediate, posterior, or pan-uveitis, or chronic non-infectious anterior uveitis.About Non-infectious Uveitis The term uveitis broadly refers to the inflammatory diseases that affect the portion of the eye known as the uvea, which is the middle of three layers that surround the eye. People with uveitis may experience decreased vision, pain, light sensitivity, and floaters. Uveitis may be caused by an infection that is commonly treated with an antimicrobial agent, or by an unknown pathogen triggering inflammation, called non-infectious uveitis. The most common form of uveitis affects the front of the uvea and is known as anterior uveitis. Other forms include intermediate uveitis, posterior uveitis, and pan uveitis. These types differ in that they all include involvement of the back portions of the uvea. Posterior uveitis refers to inflammation in the retina and the choroid, and it may result from a different immune response trigger. Pan-uveitis refers to inflammation of all three major parts of the eye. Behçet's uveitis is a well-known form of pan-uveitis. Due to the swelling of tissues critical to vision, intermediate, posterior, and pan-uveitis (which collectively make up NIU) can lead to blindness if not treated.
