Information about Ofatumumab

Ofatumumab is a recombinant human monoclonal antibody to CD20 a cell surface antigen found on pre-B and mature B lymphocytes and which is approved for use in resistant chronic lymphocytic leukemia

Liver safety of Ofatumumab

Ofatumumab therapy has not been associated with serum enzyme elevations during therapy or to cases of idiosyncratic, clinically apparent liver injury.  However, ofatumumab has potent immunosuppressive activity and its use has been associated with cases of reactivation of inactive or previously resolved hepatitis B which can be severe and can result in fatality.   

Mechanism of action of Ofatumumab

Ofatumumab (oh” fa toom’ ue mab) is a human monoclonal IgG1 antibody to the cell surface antigen CD20 (also known as human B lymphocyte restricted differentiation antigen: Bp35), which is found on mature B cells as well as 90% of neoplastic B cell such as occur in chronic lymphocytic leukemia.  CD20 is not present on pro-B cells, hematopoietic stem cells, normal plasma cells or other normal lymphocytes, circulating cells or tissues.  Engagement of ofatumumab with CD20 leads to B cell lysis and depletion of circulating and tissue B cells for an extended period, up to 6 to 8 months.  There is an accompanying mild decrease in IgM, but no change in IgG or IgA levels.
