The Therapeutic Potential of Cefiderocol in the Treatment of Multidrug-Resistant Gram-Negative Bacteria: A Narrative Review.

Background

Increasing antimicrobial resistance (AMR) is one of the leading causes of death worldwide. The predominant pathogens that exacerbate the AMR problem are multidrug-resistant (MDR) Gram-negative bacteria (GNB). Due to the increasing adaptation of MDR GNB to commercially available antimicrobial drugs, such as carbapenems as well as third- and fourth-generation cephalosporins, pharmaceutical companies around the world have been forced to produce increasingly innovative chemotherapeutics. Cefiderocol (CFDC) is a novel injectable cephalosporin 5 generation developed by Shionogi, directed against MDR GNB, including strains resistant to carbapenems.

Results

Analysis demonstrated its significant efficacy across a wide range of in vitro and in vivo studies against MDR GNB, including Carbapenem-resistant Pseudomonas aeruginosa (CRPA), Carbapenem-resistant Acinetobacter baumannii (CRAB), and carbapenem-resistant Enterobacterales (CRE) (WHO Critical Priority Pathogens). Clinical studies have shown CFDC to be an effective drug with few adverse effects.

Conclusions

When used CFDC appropriately within antibiotic stewardship guidelines, this drug is an effective, well-tolerated targeted treatment option for patients with severe clinical conditions.
