In clinical trials. Also known as GCR-3888. Related to GCR-8015/CAT-8015, which have increased affinity to CD22.
General information
Class/mechanism: Recombinant anti-CD22 immunotoxin fusion protein comprised of a murine anti-CD22 antibody fragment (disulphide-linked Fv, dsFv) and Pseudomonas exotoxin PE38. BL22 binds to CD22 positive cells and is endocytosed, resulting in intracellular release of the toxin and cell death.
The original manufacturer was acquired in 2005.[1] Development of this drug was discontinued in 2008, at which time it was superseded by the more potent and less toxic Moxetumomab pasudotox (HA22).
