More Good News for Lupus at the American College of Rheumatology Meeting

Human Genome Sciences and GlaxoSmithKline Report Details of First Positive Phase 3 Clinical Trial for Lupus

Philadelphia, October 20, 2009—Drug company Human Genome Sciences (HGS) and GlaxoSmithKline (GSK) today reported details of the first of their two crucial Phase 3 trials of belimumab (Benlysta™) in people with systemic lupus erythematosus at the American College of Rheumatology’s (ACR) annual scientific meeting in Philadelphia.

“There is a lot of encouraging information in here for the 1.5 million Americans with lupus,” said Lupus Research Institute (LRI) President Margaret G. Dowd at the meeting.

HGS first reported on the clinical trial (BLISS-52) results this summer. If findings from the longer “BLISS-76” trial due in November are positive as well, the company can apply to the Food and Drug Administration (FDA) for drug approval in 2010—possibly the first drug approval for lupus in more than 50 years.
