Microbiome impact of ibezapolstat and other infection relevant antibiotics using humanized mice.

Background: Ibezapolstat (IBZ) is a competitive inhibitor of the bacterial Pol IIIC enzyme in clinical development for treatment of infection (CDI). Previous studies demonstrated IBZ carries a favorable microbiome diversity profile compared to vancomycin (VAN). However, head-to-head comparisons with other CDI antibiotics have not been done.
