RIABNI
RIABNI is a CD20-directed cytolytic antibody indicated for the treatment of several B-cell malignancies and autoimmune disorders in adult patients. It is used to treat various forms of Non-Hodgkin’s Lymphoma and Chronic Lymphocytic Leukemia, either as a single agent or in combination with chemotherapy. The drug is also approved for managing moderately-to-severely active rheumatoid arthritis, granulomatosis with polyangiitis, microscopic polyangiitis, and pemphigus vulgaris.
How RIABNI Works
RIABNI is a monoclonal antibody that targets the CD20 antigen expressed on the surface of pre-B and mature B-lymphocytes. Once bound to CD20, the drug mediates B-cell lysis through mechanisms including complement-dependent cytotoxicity and antibody-dependent cell-mediated cytotoxicity. In autoimmune conditions, depleting these B-cells helps interrupt the inflammatory process, including the production of autoantibodies and the activation of T-cells.

Fatal infusion-related reactions within 24 hours of rituximab infusion; approximately 80% of fatal reactions occurred with first infusion. Monitor patients and discontinue RIABNI infusion for severe reactions ( 5.1 ). Severe mucocutaneous reactions, some with fatal outcomes ( 5.2 ). Hepatitis B virus (HBV) reactivation, in some cases resulting in fulminant hepatitis, hepatic failure, and death ( 5.3 ). Progressive multifocal leukoencephalopathy (PML) resulting in death ( 5.4 ). Infusion-Related Reactions Administration of rituximab products can result in serious, including fatal, infusion-related reactions. Deaths within 24 hours of rituximab infusion have occurred. Approximately 80% of fatal infusion-related reactions occurred in association with the first infusion. Monitor patients closely. Discontinue RIABNI infusion for severe reactions and provide medical treatment for Grade 3 or 4 infusion-related reactions [see Warnings and Precautions (5.1) , Adverse Reactions (6.1) ] . Severe Mucocutaneous Reactions Severe, including fatal, mucocutaneous reactions can occur in patients receiving rituximab products [see Warnings and Precautions (5.2) ] . Hepatitis B Virus (HBV) Reactivation HBV reactivation can occur in patients treated with rituximab products, in some cases resulting in fulminant hepatitis, hepatic failure, and death. Screen all patients for HBV infection before treatment initiation and monitor patients during and after treatment with RIABNI. Discontinue RIABNI and concomitant medications in the event of HBV reactivation [see Warnings and Precautions (5.3) ] . Progressive Multifocal Leukoencephalo
RIABNI Target & Pathway
ProTarget
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.
RIABNI is a lower-cost alternative to Rituxan with no clinically meaningful differences. Requires prescriber approval to substitute.
