New antibiotic tested against superbugs in chinese hospitals
NCT ID NCT07268560
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
Some bacterial infections have become resistant to common antibiotics, making them very hard to treat. This study looks at a new drug combination, aztreonam-avibactam, in about 100 hospitalized adults in China with these resistant infections. Researchers will track how well patients respond to treatment and gather information to help doctors use this drug more effectively.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Aztreonam-Avibactam (antibiotic combination)
- What this could lead to
- If successful, this study could provide real-world evidence that aztreonam-avibactam is an effective treatment for drug-resistant infections, helping doctors choose the right therapy.
- What could go wrong
- This is an observational study, not a controlled trial, so results may be less definitive. The drug is new, and long-term safety or effectiveness in diverse patients is still unknown.

Who is studied
The study population consists of hospitalized adult patients with MBL-producing CRE infections treated with ATM-AVI. Investigators will start eligibility screening and recruitment from adult patients who have received ≥24 hours of ATM-AVI. The index date is defined as the ATM-AVI initiation date, for which the date of first administration is used. The baseline period spans from 14 days before the index date to the index date, or from the date of admission to the index date, whichever is later. The observations will be both retrospective and prospective. Patients will be followed from ATM-AVI use until death, study withdrawal, or hospital discharge, whichever occurs first. For patients discharged before Day 28, a phone follow-up is necessary for assessment of the 28-day all-cause mortality.
