Mechanism of action

Rituximab targets the CD20 antigen expressed on the surface of B lymphocytes. Upon binding, it triggers multiple mechanisms of B cell death including antibody-dependent cellular cytotoxicity (ADCC), complement-dependent cytotoxicity (CDC), and direct induction of apoptosis. This results in rapid depletion of B cells, reducing autoimmune and malignant B cell populations.
