BERKELEY, Calif., July 22, 2013 (GLOBE NEWSWIRE) -- XOMA Corporation (Nasdaq:XOMA), a leader in the discovery and development of therapeutic antibodies, today confirmed it has completed patient enrollment in the Company's Phase 2 proof-of-concept (POC) study designed to evaluate the potential for gevokizumab to improve pain symptoms, physical function and structural abnormalities in patients with active inflammatory, erosive osteoarthritis of the hand (EOA) and elevated C-reactive protein (CRP) levels. XOMA's study enrolled approximately 90 patients who were randomized 2:1 to receive 60mg of gevokizumab dosed subcutaneously once monthly or placebo. The study was designed and powered to detect a significant improvement from baseline versus placebo in the mean Australian/Canadian Hand Osteoarthritis Index (AUSCAN™) pain score in the target hand at Day 84. The study also is capturing multiple outcome measures, including pain, stiffness, physical function, X-ray, radiographic and MRI changes, as well as changes in CRP and concomitant acetaminophen use, at three and six months. The Company anticipates having preliminary top-line data for the AUSCAN score in October.
XOMA also provided an update on the EOA study in patients with non-elevated CRP. This study was opened for enrollment in May, and investigators have enrolled approximately 40 patients of the targeted 90 who had qualified for the original EOA study with the exception that they did not have elevated CRP levels. This supplemental study will help inform the design of the potential Phase 3 studies of gevokizumab in EOA.
Gevokizumab 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, and modulates the cellular signaling events that produce inflammation. IL-1 beta has been shown to be involved in diverse array of disease states, including non-infectious uveitis (including Behçet's uveitis), cardiovascular disease, and other auto-inflammatory diseases.
Gevokizumab currently is being studied in a global Phase 3 clinical program, termed EYEGUARD™, which is being conducted by SERVIER and XOMA. This program is designed to determine gevokizumab's ability to treat acute non-infectious uveitis (NIU) in EYEGUARD-A, to prevent disease flares in patients with Behçet's uveitis in EYEGUARD-B, and to prevent disease flares in NIU patients who are controlled with steroids and immunosuppressants in EYEGUARD-C.
XOMA has a Proof-of-Concept (POC) program underway in which the Company is exploring the efficacy and safety of gevokizumab in multiple indications. XOMA anticipates selecting its next Phase 3 indication by the end of 2013. The Company reported data from a successful Phase 2 study in moderate to severe inflammatory acne in January 2013. XOMA anticipates full results from its two POC studies in patients with erosive osteoarthritis of the hand and data from the National Eye Institute's study of gevokizumab in patients with active non-infectious anterior scleritis later this year. Additionally, the Company recently launched a pilot study in pyoderma gangrenosum, a rare skin ulceration disease. Separately, SERVIER initiated a Phase 2 study to determine gevokizumab's ability to reduce arterial wall inflammation in patients with marked atherosclerotic plaque inflammation and who have experienced an acute coronary syndrome in the previous twelve months, as well as a POC study in polymyositis/dermatomyositis.

About Erosive Osteoarthritis of the Hand
Erosive osteoarthritis of the hand (EOA) is caused by the breakdown of the body's natural balance between cartilage formation and degradation, which leads to the narrowing of the space between the first and second joints in the fingers. Patients with EOA experience high degrees of pain, including throbbing, swelling, and prolonged periods of morning stiffness. Over time, the joints become deformed, impacting hand function and ultimately reducing EOA patients' quality of life. Approximately four million people in the U.S. have been diagnosed with EOA, and the disease affects women twelve times more often than men for reasons that are not understood by the scientific or medical community.
Published studies have highlighted interleukin 1-beta (IL-1β) for its key involvement in the development of EOA and the destruction of the cartilage matrix resulting from the disease. XOMA believes gevokizumab may be able to reduce the symptoms associated with EOA by modulating IL-1β levels. EOA is the second indication in XOMA's gevokizumab Phase 2 proof-of-concept program.
XOMA has built a portfolio of innovative therapeutic antibodies, both in late-stage clinical development and in preclinical research. 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's lead product candidate, gevokizumab (IL-1 beta modulating antibody), is in a global Phase 3 program in non-infectious uveitis with its partner SERVIER and multiple 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
