Abstract excerpt

Chemical conjugates of anti-CD22 monoclonal antibodies and toxins have been used to treat CD22+ hematological malignancies. A new anti-CD22 recombinant immunotoxin RFB4(dsFv)-PE38, composed of the Fv portion of the monoclonal antibody RFB4 fused to a truncated form of Pseudomonas exotoxin A, is being developed to target CD22+ tumor cells. To explore the potential clinical utility of this recombinant toxin in...
