Is a new polyethylene glycol (PEG)-based bowel cleansing preparation approved for use in adults prior to colonoscopy.

Broad- spectrum beta-lactam antibiotic similar in structure to the CEPHALOSPORINS except for the substitution of an oxaazabicyclo moiety for the thiaazabicyclo moiety of certain CEPHALOSPORINS. It has been proposed especially for the meningitides because it passes the blood-brain barrier and for anaerobic infections.

A second-generation pseudomonas exotoxin A-based immunotherapy targeting CD22-expressing hematologic malignancies.

NCI: A recombinant immunotoxin consisting of the Fv portion of the anti-CD22 antibody covalently fused to a 38 KDa fragment of Pseudomonas exotoxin-A (PE38) with potential antineoplastic activity. The Fv portion of moxetumomab pasudotox binds to CD22, a cell surface receptor expressed on a variety of malignant B-cells, thereby delivering the toxin moiety PE38 directly to tumor cells. Once internalized, PE38 induces caspase-mediated apoptosis via a mechanism involving mitochondrial damage and blocks translational elongation by binding to elongation factor 2 (EF-2). Moxetumomab Pasudotox exhibits a greater affinity for CD22 than its predecessor, anti-CD22 immunotoxin CAT-3888 (BL22 immunotoxin), and hence may be more effective against tumor cells expressing lower levels of CD22.
