What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study is testing whether a new antibiotic combination, cefepime/enmetazobactam, works as well as the best current treatments for complicated urinary tract infections that have spread to the bloodstream. These infections are caused by bacteria resistant to many common antibiotics. Researchers will compare how quickly the infection clears from the blood in patients receiving the new combination versus standard therapy.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
a new antibiotic combination called cefepime/enmetazobactam (FEP/META)
What this could lead to
If effective, this antibiotic combination could offer a new treatment option for hard-to-treat urinary tract infections that have spread to the blood, especially those resistant to multiple drugs.
What could go wrong
This is an observational study, not a randomized trial, so results may be less definitive. The antibiotic may not prove superior to existing treatments, and resistance could still develop.

Inclusion Criteria: * Patients with bacteremic cUTIs caused by Gram-negative bacteria treated with FEP/META or BAT * Adult population (age ≥ 18 years) * Signed informed consent form Exclusion Criteria: * Polymicrobial/mixed infections (Gram-positive bacteria or fungi together with Gram-negative microorganisms), except in cases involving multiple Gram-negative bacteria susceptible to the study drugs * Patients with negative blood cultures * Isolation of Gram-negative microorganisms not susceptible to the study drugs (e.g., KPC-producing organisms) * Patients in palliative care or with a high likelihood of death within 72 hours from the index positive blood culture * Patients treated with inappropriate therapy for more than 48 hours * Patients discharged early without follow-up blood cultures * History of significant hypersensitivity or allergic reactions to cefepime, to any of the excipients in the respective formulations, or to beta-lactamase inhibitors (e.g., tazobactam)
