It is the second radioimmunoconjugate to be approved for refractory NHL; yttrium-90 linked to ibritumomab tiuxetan (Zevalin) was approved in 2002. Tositumomab, like ibritumomab, is a monoclonal antibody of mouse origin that binds to the CD20 antigen present on the surface of >90%...

The FDA has approved Exblifep (Allecra), a fixed-dose combination of the cephalosporin cefepime and the beta-lactamase inhibitor enmetazobactam, for IV treatment of adults with complicated urinary tract infections (cUTIs), including pyelonephritis, caused by designated susceptible microorganisms (see Spectrum of Activity).
