PURPOSE OF REVIEW: To discuss the current literature on novel agents for the treatment of carbapenem-resistant nonfermenting Gram-negative bacteria (NF-GNB) infections.

RECENT FINDINGS: Some novel agents have recently become available that are expected to replace classical polymyxins as the first-line options for the treatment of carbapenem-resistant NF-GNB infections.

SUMMARY: In this narrative review, we provide a brief overview of the differential activity of various recently approved agents against NF-GNB most encountered in the daily clinical practice, as well as the results from phase-3 randomized clinical trials and large postapproval observational studies, with special focus on NF-GNB. Since resistance to novel agents has already been reported, the use of novel agents needs to be optimized, based on their differential activity (not only in terms of targeted bacteria, but also of resistance determinants), the local microbiological epidemiology, and the most updated pharmacokinetic/pharmacodynamic data. Large real-life experiences remain of crucial importance for further refining the optimal treatment of NF-GNB infections in the daily clinical practice.
