HOW BENLYSTA WORKS

  • 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.
