BENLYSTA is an investigational human monoclonal antibody drug and the first in a new class of drugs called BLyS-specific inhibitors. On March 9, 2011, Human Genome Sciences and GlaxoSmithKline PLC (GSK) announced that the U.S. Food and Drug Administration (FDA) has approved BENLYSTA for the treatment of adult patients with active, autoantibody-positive systemic lupus erythematosus (SLE) who are receiving standard therapy.
The label for BENLYSTA includes the following limitations of use: The efficacy of belimumab has not been evaluated in patients with severe active lupus nephritis or severe active central nervous system lupus, and has not been studied in combination with other biologics or intravenous cyclophosphamide. Use of belimumab is therefore not recommended in these situations.

How BENLYSTA Works
Belimumab blocks the binding of soluble BLyS, a B-cell survival factor, to its receptors on B cells. Belimumab does not bind B cells directly, but by binding BLyS, belimumab inhibits the survival of B cells, including autoreactive B cells, and reduces the differentiation of B cells into immunoglobulin-producing plasma cells. BLyS is a naturally occurring protein which was discovered by HGS in 1996.
Collaboration with GlaxoSmithKline
In August 2006, HGS and GSK entered into a co-development and commercialization agreement under which HGS conducted the BENLYSTA Phase 3 trials, with assistance from GSK. The companies share equally in Phase 3/4 development costs, sales and marketing expenses, and profits of any product commercialized under the agreement.
How BENLYSTA Was Discovered
HGS first discovered the naturally occurring protein, BLyS or B-lymphocyte stimulator, in 1996 and published a preliminary description of its activity in the journal, Science, in July 1999. Following that discovery, HGS initiated a program to develop human monoclonal antibodies that would specifically recognize and inhibit the biological activity of BLyS. BENLYSTA is a human monoclonal antibody that HGS generated through a collaboration with Cambridge Antibody Technology.
