Multiple clinical studies with other BAFF antagonists recently have reported on BAFF's potential positive role in treating lupus and rheumatoid arthritis. Anthera is advancing its development of blisibimod, a broad inhibitor of BAFF, to expand its potential clinical utility in autoimmune diseases. Blisibimod is a novel fusion protein called a peptibody and is distinct from an antibody. Anthera owns worldwide rights to blisibimod in all potential indications."
