Summary of Clinical Use
Used to treat CD20-positive non-Hodgkins lymphoma, chronic lymphocytic leukemia, and several autoimmune conditions (severe active, DMARD/TNF inhibitor-refracrtory rheumatoid arthritis; severe, active granulomatosis with polyangiitis (Wegener's, GPA); microscopic polyangiitis (MPA)). Rituximab is also used to suppress antibody-mediated rejection in living-donor kidney recipients prior to an ABO-incompatible transplant [4-5].
A modified formulation containing rituximab + human hyaluronidase (Rituxan Hycela) that can be delivered subcutaneously (the original rituximab only formulation has to be administered intravenously) was FDA approved in June 2017 for the treatment of previously untreated and relapsed or refractory follicular lymphoma, previously untreated diffuse large B-cell lymphoma (DLBCL), and previously untreated and previously treated chronic lymphocytic leukemia (CLL).
In June 2018, the FDA approved the use of rituximab as a much needed treatment for the potentially life-threatening skin disease pemphigus vulgaris (PV), for use in adult patients with moderate to severe disease. EMA approval for the treatment of PV patients followed in March 2019.
Mechanism Of Action and Pharmacodynamic Effects
Anti-CD20 monoclonal antibody. The Fab regions of this antibody bind to the CD20 antigen on B lymphocytes, and the Fc domain recruits antibodies and complements to mediate cell lysis.
