Blisibimod (Gly-005CL)

Blisibimod (also known as A-623, formerly AMG 623) is a selective antagonist of B-cell activating factor (BAFF, also known as B-lymphocyte stimulator or BLyS), being developed by Anthera Pharmaceuticals as a treatment for systemic lupus erythematosus. It is currently under active investigation in clinical trials.

Mechanism of Action
B cell activating factor inhibitors.
Blisibimod is a fusion protein consisting of four BAFF binding domains fused to the N-terminus of the fragment crystallizable region (Fc) of a human antibody.
BAFF is involved in B-cell survival, activation, and differentiation. Elevated levels of BAFF have been associated with several B-cell mediated autoimmune diseases, including systemic lupus erythematosus, lupus nephritis, rheumatoid arthritis, multiple sclerosis, Sjögren's syndrome, Graves' disease, and Hashimoto's thyroiditis. Blisibimod binds to BAFF and inhibits interaction with BAFF receptors, thus decreasing B-cell survival and proliferation throughout the body. Improvements in disease activity have been observed in patients with systemic lupus erythematosus and rheumatoid arthritis following treatment with BAFF inhibitors in clinical trials.
