Mechanism of action

Belimumab is a monoclonal antibody that binds to and neutralizes soluble B-lymphocyte stimulator (BLyS), a key cytokine that promotes B cell survival and differentiation. By reducing BLyS signaling, belimumab decreases pathogenic autoantibody-producing B cells. The combination with early vaccination aims to leverage the immunosuppressive window created by belimumab to promote tolerogenic responses and prevent disease flares.
