Targeted mechanism of action

See how BENLYSTA works.

BENLYSTA is the only FDA-approved treatment designed to target BLyS/BAFF, an underlying cause of lupus and lupus nephritis1,2

video transcript

NARRATOR:
BENLYSTA (belimumab) is designed for lupus. BENLYSTA is the only biologic with a mechanism of action that selectively targets the B-lymphocyte stimulator protein, or BLyS, a known underlying cause of systemic lupus erythematosus, or SLE, with or without lupus nephritis.

NARRATOR:
Although it does not bind to B cells directly, BENLYSTA inhibits the survival of autoreactive B cells and reduces the differentiation of B cells into immunoglobulin-producing plasma cells. The clinical relevance of these effects on B cells has not been established.

NARRATOR:
In patients with lupus who were positive for anti-double-stranded DNA, treatment with BENLYSTA resulted in a 41% reduction in anti-double-stranded DNA antibody levels over 52 weeks. Reductions were also seen in IgG CD19 positive, CD20 positive, naïve B cells, activated B cells, and the SLE B-cell subset at Week 52. Additionally increases in complement proteins C3 and C4 were also observed at Week 52 in patients with low complement levels at baseline.

NARRATOR:
In patients with lupus nephritis, treatment with BENLYSTA led to a decrease in serum IgG as early as Week 4, and, subsequently, there was an increase in serum IgG levels, which was associated with decreased proteinuria. Reductions in autoantibodies, total circulating B cells, and B-cell subsets and increases in complement proteins were consistent with what was observed in SLE trials.

* BENLYSTA does not directly bind to B-cells or directly deplete B-cell population.3,4

BAFF = B-cell activating factor; BLyS = B-lymphocyte stimulator protein.

Reductions in B-cell populations

In patients with active lupus nephritis, reductions in circulating total B-cells and B‑cell subsets observed were consistent with lupus studies.
