RiTUXimab Injection [Truxima]

Laida Cuevas Palomares · FDA-approved active Small molecule

Rituximab is a chimeric monoclonal antibody that binds to CD20 on B cells, leading to their depletion through antibody-dependent cellular cytotoxicity and direct apoptosis.

Rituximab Injection (Truxima) is a biosimilar monoclonal antibody targeting CD20-positive B cells, used primarily in the treatment of non-Hodgkin's lymphoma and chronic lymphocytic leukemia. It has no FDA label or clinical trials listed, indicating limited regulatory approval and research activity.

Mechanism of action

Rituximab targets the CD20 antigen expressed on the surface of B lymphocytes. Upon binding, it triggers multiple mechanisms of B cell destruction 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.
