In Vitro Activity of Cefepime-Enmetazobactam against Enterobacterales Isolated from Cancer Patients (ASM Microbe 2025) - "Isolates resistant to third-generation cephalosporins and isolates nonsusceptible to meropenem were screened for the presence of ß-lactamases. Cefepime/enmetazobactam showed excellent activity against most of the Enterobacterales isolates. Excellent activity was seen against third-generation cephalosporin resistant isolates. Cefepime/enmetazobactam exhibited higher activity than Piperacillin-tazobactam and Cefeperazone-sulbactam suggesting a good therapeutic alternative as compared with carbapenems against ESBL producers."

New β-Lactam/β-Lactamase Inhibitor Combination Antibiotics. (PubMed, Pathogens) - "During the last 2 years from the writing of this article, cefepime/enmetazobactam, aztreonam/avibactam, and sulbactam/durlobactam were approved for use in clinical practice. Aztreonam/avibactam is indicated for the treatment of adult patients who suffer from complicated intra-abdominal infections, complicated urinary tract infections including pyelonephritis, hospital-acquired pneumonia, and ventilator-associated pneumonia due to aerobic Gram-negative infections with limited therapeutic options. Sulbactam/durlobactam, a combination of 2 β-lactamase inhibitors, is indicated for the treatment of adult patients with hospital-acquired bacterial pneumonia and ventilator-associated bacterial pneumonia due to the Acinetobacter baumannii-calcoaceticus complex [including carbapenem-resistant Acinetobacter baumannii (CRAB) infections]."

Diagnostic algorithm for the detection of carbapenemases and extended-spectrum β-lactamases in carbapenem-resistant Pseudomonas aeruginosa. (PubMed, Microbiol Spectr) - "We used the following BL-BLI combinations: ceftolozane-tazobactam (C-T), ceftazidime-avibactam, imipenem-relebactam (I-R), meropenem-vaborbactam, cefepime-enmetazobactam (C-E), and aztreonam-avibactam. This method is particularly valuable for laboratories lacking access to molecular diagnostics, as it provides a practical alternative for routine testing. By facilitating the early detection of resistant P. aeruginosa strains, this approach has the potential to improve patient outcomes, optimize antimicrobial therapy, and enhance global surveillance efforts against multidrug-resistant pathogens."

Critical reappraisal of current issues for improving the proper clinical use of the incoming beta-lactam/beta-lactamase inhibitor combinations of tomorrow. (PubMed, Expert Rev Anti Infect Ther) - "A literature search was performed on PubMed-MEDLINE (until December 2024) for retrieving available studies on cefepime-enmetazobactam, sulbactam-durlobactam, and cefepime-taniborbactam. Overall, old habits die hard and issues retrieved with licensed beta-lactams emerged also with novel BL/BLIc of tomorrow, potentially affecting their efficacy when used in real-world practice. Adopting appropriate corrective measures for overcoming these issues might increase the likelihood of preserving their efficacy in the future by minimizing the propensity risk of resistance development."

Antimicrobial activity of cephamycins and β-lactam/β-lactamase inhibitors against ESBL-producing Escherichia coli and Klebsiella pneumoniae under standard and high bacterial inocula. (PubMed, Sci Rep) - "At the higher inoculum size, cefoxitin, cefmetazole, flomoxef, ceftolozane/tazobactam, ceftazidime/avibactam, cefepime/enmetazobactam, and imipenem/relebactam demonstrated in vitro efficacy against 48.3%, 75.9%, 70.0%, 0%, 82.8%, 100%, 89.7% of the ESBL-producing isolates. Cephamycins demonstrated high in vitro activity against ESBL-producing isolates at standard inoculum sizes. However, the in vitro time-kill experiments revealed that the efficacy of cephamycins is not fully maintained at high inoculum sizes."

β-Lactam/β-Lactamase Inhibitor Combination Antibiotics Under Development. (PubMed, Pathogens) - "The incorporation of ceftolozane/tazobactam, ceftazidime/avibactam, meropenem/vaborbactam, and imipenem/cilastatin/relebactam has provided new therapeutic options in the treatment of patients with infections due to MDR pathogens. Cefiderocol along with cefepime/enmetazobactam, avibactam/aztreonam, and sulbactam/durlobactam have been recently added to these agents as therapeutic choices, particularly for metallo-β-lactamase producing Gram-negative bacteria...However, only a few have advanced through phase 1, 2, and 3 clinical trials. Among them, in this article, we focus on the most promising combinations of cefepime/zidebactam, cefepime/taniborbactam, and imipenem/cilastatin/funobactam, which are currently under investigation in phase 3 trials."

Cefepime-enmetazobactam: first approved cefepime-β- lactamase inhibitor combination for multi-drug resistant Enterobacterales. (PubMed, Future Microbiol) - "The targeted activity of cefepime-enmetazobactam against ESBLs infections which are resistant to common antibiotics, together with its superior results against piperacillin/tazobactam in a phase 3 trial make this new BL/BLI combination an effective carbapenem sparing option for the treatment of serious infections caused by ESBLs-producing Enterobacterales. In addition, if clinical data are supportive, cefepime-enmetazobactam has a potential role in the treatment of pathogens co-producing OXA-48 like enzymes along with ESBLs."
