Novel Specific Metallo-ß-lactamase Inhibitor, ANT2681, Restores Meropenem Activity to Clinically Effective Levels Against NDM-Positive Enterobacterales.

Antimicrob Agents Chemother 2021 Apr 5. Epub 2021 Apr 5.

Antabio SAS, Labège, France.

The global dissemination of metallo-ß-lactamase (MBL)-producing carbapenem resistant Enterobacterales (CRE) is a serious public health concern. Specifically, NDM (New Delhi MBL) has been a major cause of carbapenem therapy failures in recent years, particularly as effective treatments for serine-ß-lactamase (SBL)-producing Enterobacterales are now commercially available. Since the NDM gene is carried on promiscuous plasmids encoding multiple additional resistance determinants, a large proportion of NDM-CREs are also resistant to many commonly used antibiotics, resulting in limited and sub-optimal treatment options.
