TRUXIMA

RITUXIMAB-ABBS CD20-directed Antibody Interactions
Oncology Approved 2018-11-28

Truxima (rituximab-abbs) is a CD20-directed cytolytic antibody indicated for the treatment of several B-cell malignancies and autoimmune disorders in adult patients. It is utilized in the management of specific forms of Non-Hodgkin’s Lymphoma and Chronic Lymphocytic Leukemia, frequently in combination with chemotherapy regimens. The drug is also indicated for autoimmune conditions including rheumatoid arthritis, granulomatosis with polyangiitis, microscopic polyangiitis, and pemphigus vulgaris. Its therapeutic role focuses on depleting B-cells that contribute to both oncogenic progression and chronic inflammatory processes.

How TRUXIMA Works

Truxima is a monoclonal antibody designed to target the CD20 antigen expressed on the surface of pre-B and mature B-lymphocytes. Upon binding to this antigen, the drug mediates B-cell lysis through mechanisms including complement-dependent cytotoxicity and antibody-dependent cell-mediated cytotoxicity. In autoimmune settings like rheumatoid arthritis, the depletion of B-cells helps interrupt the inflammatory process by reducing autoantibody production and proinflammatory cytokine release. This targeted action allows for the reduction of B-cell populations involved in both malignancy and autoimmune-mediated tissue damage.

TRUXIMA Target & Pathway

Pro

Target

CD20 (B-Lymphocyte Antigen CD20) Cell Surface Marker

A protein found on the surface of B-cells but not stem cells or plasma cells. Anti-CD20 antibodies deplete B-cells, making them effective in B-cell cancers and autoimmune diseases where B-cells drive pathology.

Biosimilar for Rituxan

TRUXIMA is a lower-cost alternative to Rituxan with no clinically meaningful differences. Requires prescriber approval to substitute.
