Furthermore, the prevalence of metallo-β-lactamase (MBL)-producing CRE and CR-PA is increasing, which are capable of hydrolyzing nearly all β-lactam antibiotics. Cefepime-taniborbactam (FTB) is a novel bicyclic boronate β-lactam-β-lactamase inhibitor combination with direct inhibitory activity against MBLs (Ambler Class B), in addition to Ambler Class A, C, and D serine-β-lactamases. FTB has demonstrated high in vitro activity against CRE and CR-PA, including isolates producing NDM, VIM, KPC, AmpC, OXA-48, and extended-spectrum β-lactamases (ESBLs). Furthermore, FTB has demonstrated in vitro activity against Stenotrophomonas maltophilia and Burkholderia cepacia complex. Resistance to FTB is observed in isolates producing IMP, as well as MBL variants NDM-9, NDM-30, and VIM-83. FTB remains susceptible to non-β-lactamase resistance mechanisms, including penicillin-binding protein 3 (PBP3) target mutations. The pharmacodynamic driver of taniborbactam efficacy is the ratio of the area under the curve to the minimum inhibitory concentration (AUC/MIC), and the study dose of FTB 2 g/0.5 g every 8 h infused over 2 h achieves sufficient serum and tissue exposures to maintain therapeutic efficacy.
