Many nonhuman proteins have useful pharmacological activities, but are infrequently effective in humans because of their high immunogenicity. A recombinant immunotoxin (HA22, CAT8015, moxetumomab pasudotox) composed of an anti-CD22 antibody variable fragment fused to PE38, a 38-kDa portion of Pseudomonas exotoxin A, has produced many complete remissions in drug-resistant hairy-cell leukemia whe...

Transforming growth factor alpha-Pseudomonas exotoxin-40 (TP40) is a hybrid fusion protein that selectively binds to cancer cells that express the epidermal growth factor receptor. TP40 is then internalized and kills these cells by virtue of its Pseudomonas exotoxin-derived domains. We studied the safety and short-term antitumor activity of intravesical TP40 in 43 patients with refractory super...

Diphtheria toxin (DT), Pseudomonas aeruginosa Exotoxin A (ETA) and cholix toxin from Vibrio cholerae share the same mechanism of toxicity; these enzymes ADP-rybosylate elongation factor-2 (EF-2) on a modified histidine residue called diphthamide, leading to a block in protein synthesis. Mutant Chinese hamster ovary cells that are defective in the formation of diphthamide have no distinct phenot...
