Monoclonal Antibodies That Mimic the Action of Intravenous Immunoglobulin Can Inhibit Immune Thrombocytopenia

March 01, 2002

Intravenous immunoglobulin (IVIG) is prepared from large pools of plasma from healthy donors and is widely used to treat autoimmune diseases, especially immune thrombocytopenic purpura (ITP). Human polyclonal antierythrocyte antibodies, such as anti-D, can also be effective at treating ITP in individuals expressing the appropriate antigen. The demand for IVIG and anti-D exceeds the supply, and the development of a recombinant product to replace these human-derived blood products would be highly desirable. We have hypothesized that monoclonal antibodies directed against red cells may be effective in inhibiting immune forms of thrombocytopenia.
