XOMA Initiates Phase 3 Gevokizumab Trial in Patients With Non-Infectious Uveitis and Phase 2 Gevokizumab Trial in Patients With Erosive Osteoarthritis
BERKELEY, Calif., June 27, 2012 (GLOBE NEWSWIRE) -- XOMA Corporation (Nasdaq:XOMA) today announced it has opened enrollment in two clinical trials to determine gevokizumab's potential to treat interleukin-1 beta-mediated inflammatory diseases. The first trial is XOMA's global Phase 3 study investigating the ability of gevokizumab to reduce the signs and symptoms, including vitreous haze, in patients with non-infectious uveitis (NIU) involving the intermediate and/or posterior segment of the eye. The second trial is a Phase 2 study to evaluate the potential for gevokizumab to improve pain symptoms, physical function and structural abnormalities in patients with erosive osteoarthritis of the hand. Patients currently are being screened in both trials.

"Today represents an historic milestone for XOMA, as we launch the first global Phase 3 program for a XOMA-created product to which we retain U.S. commercial rights," stated John Varian, Chief Executive Officer of XOMA. "Our clinical and regulatory teams have worked diligently with their colleagues from Servier to design the gevokizumab NIU trial to meet the requirements of regulatory agencies, including the FDA, in this indication."

In this study, titled A Randomized, Double-masked, Placebo-controlled Study of the Safety and Efficacy of Gevokizumab in the Treatment of Active Non-infectious Intermediate, Posterior, or Pan-Uveitis, the Company intends to enroll patients with active non-infectious intermediate, posterior, or pan-uveitis with a vitreous haze score equal to or greater than 2+ on the Standardization of Uveitis Nomenclature (SUN) / National Eye Institute (NEI) scale in at least one eye. They will be randomized to receive either one of two doses of gevokizumab or placebo. The study's primary endpoint is the proportion of patients demonstrating a significant reduction in vitreous haze score on Day 56. The study also will assess the effect of gevokizumab on additional endpoints, including response rates at other time points and changes from baseline in visual acuity.

Paul Rubin, M.D., XOMA's Senior Vice President of Research and Development and Chief Medical Officer, stated, "As preclinical and clinical data have shown that IL-1 beta is an important contributor to the inflammation seen in uveitis, we believe gevokizumab's ability to potently inhibit IL-1 beta signaling could be relevant in controlling this inflammation, as well as the inflammation associated with other conditions. Because of this, we established a proof-of-concept program in November 2011 to lead us to additional indications for this antibody. Included in this program is the ongoing trial in moderate to severe acne vulgaris from which we anticipate top-line data by year end. Today, we opened enrollment in the second POC indication, erosive osteoarthritis of the hand, which we believe will complete enrollment sometime around the end of 2012."

XOMA's Phase 2 proof-of-concept study of gevokizumab in active inflammatory, erosive osteoarthritis of the hand is designed to enroll approximately 90 patients who will be randomized to receive gevokizumab or placebo. The study is 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 three months. The study also will capture multiple outcome measures including pain, stiffness, physical function, radiographic and MRI changes, as well as changes in C-reactive protein and concomitant acetaminophen use.
