Human Genome Sciences, Inc. (Nasdaq:HGSI) and Lonza announced an agreement for the future commercial supply of BENLYSTA® (belimumab), which is currently under regulatory review in the United States and Europe as a potential new treatment for systemic lupus erythematosus (SLE). BENLYSTA is being developed by HGS and GlaxoSmithKline (GSK) under a co-development and commercialization agreement entered into in 2006.

"Our HGS large-scale manufacturing facility has ample capacity to provide worldwide supply of BENLYSTA following approval, and for the first two or three years following launch," said Randy J. Maddux, Vice President, Manufacturing Operations, HGS. "However, we believe that we will eventually require additional capacity. After a careful review of proposals from a number of highly qualified commercial manufacturing organizations, we have selected Lonza, a leader in biologics manufacturing with a global network of large-scale production sites. We are confident that Lonza is the right choice to fill this critically important role."

In June 2010, GSK submitted a Marketing Authorization Application to the European Medicines Agency, seeking approval to market belimumab in Europe for treatment of autoantibody-positive patients with SLE, and HGS submitted a Biologics License Application (BLA) to the U.S. Food and Drug Administration seeking approval to market belimumab in the United States. No new drug for lupus has been approved by regulatory authorities in more than 50 years.

"We are enthusiastic about supporting the future production of BENLYSTA with our cutting-edge capabilities and expertise in biopharmaceutical manufacturing," said Dr. Stephan Kutzer, Chief Operating Officer, Lonza Custom Manufacturing. "Working on such an important new drug for lupus patients will be very rewarding and the basis for a long-term, collaborative relationship with HGS."

About BENLYSTA (belimumab)

Belimumab is an investigational human monoclonal antibody drug that specifically recognizes and inhibits the biological activity of B-lymphocyte stimulator, or BLyS. BLyS is a naturally occurring protein discovered by HGS that is required for the development of B-lymphocyte cells into mature plasma B cells. Plasma B cells produce antibodies, the body's first line of defense against infection. In lupus and certain other autoimmune diseases, elevated levels of BLyS are believed to contribute to the production of autoantibodies - antibodies that attack and destroy the body's own healthy tissues. The presence of autoantibodies appears to correlate with disease severity. Preclinical and clinical studies demonstrated that belimumab reduced autoantibody levels in SLE. The results of two pivotal Phase 3 trials, BLISS-52 and BLISS-76, demonstrated that belimumab reduced SLE disease activity.
