Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A phase 1, randomized, double blind, placebo controlled drug-drug interaction, pharmacokinetics and safety study of cefiderocol in combination with xeruborbactam in healthy adult participants

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Qpex Biopharma, Inc. is developing xeruborbactam, a new boron-based beta-lactamase inhibitor with activity against both serine and metallo-beta-lactamases in combination with a beta-lactam antibiotic.

Cefiderocol is a cephalosporin antibiotic approved in the US for the treatment of complicated urinary tract infections including pyelonephritis, and hospital-acquired bacterial pneumonia and ventilator-associated bacterial pneumonia.
