Summary of Clinical Use ![]() |
Approved to treat systematic lupus erythematosus (SLE) [3-4]. The original formulation of belimumab was administered intravenously. In July 2017, a new self-injectable subcutaneous formulation of belimumab for the treatment of adult patients with active, autoantibody‑positive SLE was FDA approved, which allows self-administration of medication at home as an alternative to attending a medical facility to receive an i.v. infusion. Additional indications being evaluated with belimumab include vasculitis (Phase 3), and myaesthenia gravis and transplant rejection (both Phase 2). |
Mechanism Of Action and Pharmacodynamic Effects ![]() |
Suppresses B-cell mediated immunity and the autoimmune response by binding to circulating soluble TNFSF13B (BAFF; BLyS), effectively reducing the amount of TNFSF13B available to mediate B-cell activation [2,5]. |
