Based on 1 publication(s) in Google Scholar
Bezlotoxumab (BLA761046; MBL-CDB1; MDX-1388) is a fully humanized IgG1/kappa monoclonal antibody directed against Clostridium difficile toxin B. Bezlotoxumab mediates the early reconstitution of gut microbiota to reduce the risk of recurrent Clostridium difficile infection (CDI). Bezlotoxumab can be used for the study of recurrent Clostridium difficile infection prevention.
