New antibiotic takes on superbug in major hospital study
NCT ID NCT07226557
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether the antibiotic cefiderocol can lower death rates in hospitalized adults with a tough, drug-resistant Acinetobacter infection. Researchers will compare patients who got cefiderocol to those who received the best available treatment. The goal is to see which approach works better over 28 days.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- cefiderocol
- What this could lead to
- If cefiderocol works better, it could become a go-to treatment for tough hospital infections that resist other antibiotics.
- What could go wrong
- This is an observational analysis, not a controlled trial, so results may be less reliable. The infection is rare and severe, so findings may not apply broadly.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Hospitalized adult patients with a clinical culture positive for carbapenem resistant A. baumannii and received an antibiotic with possible in vitro activity against carbapenem resistant A. baumannii in the time frame of interest (i.e., days before culture collection until 2 days after first available antibiotic susceptibility test result was made available) and admitted to US hospitals reporting to the PINC-AI healthcare database between 2018-2024 will be eligible for inclusion in the hypothetical target trials.

Inclusion Criteria: * Hospitalized adults (≥ 18 years of age) * Carbapenem resistant A. baumannii-calcoaceticus complex clinical culture * Antimicrobial agent with possible in vitro activity against carbapenem resistant A. baumannii-calcoaceticus complex initiated in the time frame of 2 days before culture collection until 2 days following first available antibiotic susceptibility test result being made available Exclusion Criteria: * Patients with no antibiotic susceptibility testing * Patients with only A. baumannii infection diagnosed by rapid diagnostic tests (i.e., multiplex polymerase chain reaction) * Initiation of antimicrobial agent outside of selected time frame (i.e., 2 days before culture collection until 2 days after first available antibiotic susceptibility test result was made available)
