What You Need to Know Before You Apply

What is the purpose of this trial?

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

Do I need to stop my current medications to join the trial?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Is the combination of Xeruborbactam and Cefiderocol safe for humans?

Cefiderocol, also known as Fetroja, has been studied in clinical trials and generally showed a good safety profile, but some studies reported higher mortality rates in patients with severe infections. Common side effects include stomach issues like diarrhea and nausea. ^{1 2 3 4 5}

What makes the drug Xeruborbactam/Cefiderocol unique for bacterial infections?

Xeruborbactam/Cefiderocol is unique because it combines cefiderocol, a novel siderophore cephalosporin that uses iron transport channels to penetrate Gram-negative bacteria, with xeruborbactam, potentially enhancing its effectiveness against multidrug-resistant strains. This combination targets serious Gram-negative bacterial infections, offering a new option for patients with limited treatment choices. ^{1 2 3 4 6}

What data supports the effectiveness of the drug Xeruborbactam/Cefiderocol for bacterial infections?

Cefiderocol, a component of the drug, has shown effectiveness in treating serious Gram-negative bacterial infections, including complicated urinary tract infections and pneumonia, by overcoming many bacterial resistance mechanisms. However, some studies noted higher mortality rates in patients treated with cefiderocol, indicating the need for careful consideration in its use. ^{1 2 3 4 6}

What Are the Treatments Tested in This Trial?

Interventions

• Xeruborbactam/Cefiderocol

Trial Overview The study tests the interaction between Xeruborbactam and Cefiderocol, both antibiotics, in healthy adults. It's randomized and placebo-controlled, meaning some people get the real drugs while others get an inactive substance without knowing which one they received.

How Is the Trial Designed?

Group I: Single Dose Cohorts Experimental Treatment 3 Interventions

Administered single fixed dose of Xeruborbactam Administered single fixed dose of Cefiderocol Administered single fixed dose of a combination of Xeruborbactam and Cefiderocol.

Group II: Single Dose Cohorts Placebo Placebo Group 1 Intervention

5% Dextrose in water

Xeruborbactam/Cefiderocol is already approved in United States for the following indications:

Approved in United States as Fetroja (cefiderocol) for:

• Complicated urinary tract infections including pyelonephritis
• Hospital-acquired bacterial pneumonia and ventilator-associated bacterial pneumonia

Published Research Related to This Trial

Cefiderocol is the first siderophore cephalosporin approved for treating serious Gram-negative bacterial infections, showing strong effectiveness against multidrug-resistant strains and stability against various β-lactamases.

In clinical trials, cefiderocol was found to be noninferior to standard treatments for complicated urinary tract infections and nosocomial pneumonia, although it had a higher all-cause mortality rate in patients with carbapenem-resistant infections, indicating the need for careful patient selection.

Cefiderocol: A Review in Serious Gram-Negative Bacterial Infections. Syed, YY.[2023]

Cefiderocol is a new antibiotic that effectively targets Gram-negative bacteria by utilizing their iron transport systems, making it a promising option for treating complicated urinary tract infections and certain types of pneumonia in adults with limited treatment options.

However, the CREDIBLE-CR trial indicated a higher all-cause mortality in patients treated with cefiderocol, particularly those with severe infections from Acinetobacter spp., highlighting the need for further phase III studies to assess its safety and efficacy in serious infections.

Cefiderocol, a new antibiotic against multidrug-resistant Gram-negative bacteria. Silva, JT., López-Medrano, F.[2023]

Cefiderocol is a new antibiotic effective against difficult-to-treat gram-negative bacteria, including those resistant to carbapenems, as shown in clinical trials for hospital-acquired pneumonia.

Despite its efficacy, a clinical trial indicated an increase in mortality in patients treated with cefiderocol, highlighting the need for further evaluation of its safety and effectiveness in real-world settings.

Cefiderocol. Soriano, MC., Montufar, J., Blandino-Ortiz, A.[2023]

Cefiderocol is a newly approved antibiotic that shows effectiveness against multidrug-resistant (MDR) bacteria, including common pathogens in cystic fibrosis patients, such as Pseudomonas aeruginosa and Stenotrophomonas maltophilia.

While cefiderocol has demonstrated potential with minimum inhibitory concentrations (MICs) of ≤4 mg/L, there is currently no in vivo evidence specifically in cystic fibrosis patients, suggesting it should be considered when other treatment options are limited.

Does Cefiderocol Have a Potential Role in Cystic Fibrosis Pulmonary Exacerbation Management? Gavioli, EM., Guardado, N., Haniff, F., et al.[2023]

Cefiderocol is effective against complicated urinary tract infections (cUTIs) caused by Gram-negative bacteria, showing a higher clinical and microbiological eradication rate compared to imipenem-cilastatin (73% vs. 55%).

Despite its efficacy, cefiderocol is associated with higher all-cause mortality in certain patients, and its use should be restricted to cases where alternative treatments are limited, particularly in patients with renal impairment.

Cefiderocol, a New Siderophore Cephalosporin for the Treatment of Complicated Urinary Tract Infections Caused by Multidrug-Resistant Pathogens: Preclinical and Clinical Pharmacokinetics, Pharmacodynamics, Efficacy and Safety. Lee, YR., Yeo, S.[2023]

Cefiderocol is a novel antibiotic that effectively targets multi-drug resistant (MDR) Gram-negative bacteria by utilizing a unique mechanism that allows it to transport iron across bacterial membranes, leading to cell wall synthesis inhibition.

While cefiderocol showed non-inferiority to other antibiotics like imipenem and meropenem in treating complicated urinary tract infections and hospital-acquired pneumonia, it was associated with higher all-cause mortality in patients with severe infections from Acinetobacter spp., highlighting the need for careful patient selection.
