 Rituximab: The RA Smart-Bomb
Rituximab has already been proven to be of immense value in treating a variety of other diseases in which B cell activity plays a primary role, and its use in non-Hodgkin's lymphoma has revolutionized the current approach to treatment.
Increasingly, rituximab has been utilized to deplete B cell populations in non-malignant diseases, especially those illnesses which have been designated autoimmune in nature.
Now, based upon recent work which has implicated certain B cells in the destructive processes of rheumatoid arthritis, rituximab has been shown to be beneficial in lessening the destructive immune activity which is the basis of the disease.
