Lupus drug Benlysta has been approved by the Food and Drug Administration, becoming the first new lupus drug approved in 56 years.

The intravenous drug  was developed by Maryland-based Human Genome Sciences (NASDAQ:HGSI) and GlaxoSmithKline (NYSE:GSK), the British pharmaceutical giant which maintains its American headquarters in Research Triangle Park, North Carolina.

Lupus is an autoimmune disease, affecting primarily women, in which the body attacks healthy tissues. Benlysta works by inhibiting a protein, in turn reducing the number of abnormal cells thought to be a problem in lupus.

Benlysta has been in development for more than 15 years. Discovered by HGS in 1996, the company entered into a co-development and commercialization agreement with GSK 10 years later. Some industry observers have said the drug could become a blockbuster.

But tests show that the drug doesn’t work on everyone. In two clinical studies, African American patients and patients of African heritage did not appear to respond to treatment with the drug. No definitive conclusion was reached and to address this concern. HGS and GSK will conduct additional studies.
