Abstract

The invention relates to the discovery that contacting CD22+-cancer cells with both an anti-CD22 immunotoxin whose toxin portion is a protein synthesis inhibitor and a chemotherapeutic agent that inhibits protein synthesis results in greater cytotoxicity to the cells than would be expected. This synergistic effect can be exploited to inhibit the growth of CD22+ B cell cancers.
