LUNSUMIO is a bispecific antibody designed to simultaneously bind to proteins on T cells and B cells
LUNSUMIO is a first-of-its-kind bispecific antibody therapy for relapsed and refractory FL. It is designed to attach to CD3, a protein on the surface of T-cells (a type of white blood cell) and CD20, a protein on the surface of B cells. This dual binding process is thought to bring your T cells close enough to engage with and release a type of protein called cytokines to kill cancerous B cells. However, it may also harm healthy cells.
