Could shorter antibiotic courses be safer for ventilator pneumonia?
NCT ID NCT05545735
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at whether giving antibiotics for 4 days instead of the usual 7 days is safe and effective for patients with ventilator-associated pneumonia (VAP). The goal was to reduce side effects from antibiotics while still treating the infection. The trial was stopped early after enrolling only 27 surgical patients, so the findings are limited.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- antibiotics
- What this could lead to
- If successful, this could show that a shorter course of antibiotics is safe and effective for early ventilator-associated pneumonia, reducing side effects and antibiotic resistance.
- What could go wrong
- The trial was terminated early with only 27 participants, so results are limited and may not be reliable. Shorter treatment might not clear the infection in all patients.

Inclusion Criteria: 1. Surgical patient 2. Early VAP, defined as VAP occurring within 2 - 7 days of intubation (via endotracheal or tracheostomy tube) (9). VAP will be defined according to local institutional protocol. 3. Hospital length of stay (LOS) \< 10 days at the time of VAP diagnosis. 4. Patients are willing to provide informed consent or their Legally Authorized Representative (LAR) is willing to provide informed consent on their behalf when the patient is unable (i.e., cognitively impaired from sedation on a ventilator) Exclusion Criteria: 1. Age \< 18 years 2. Prior episode of VAP for the index admission 3. VAP caused by any of the following pathogens: * Methicillin-resistant Staphylococcus aureus (MRSA) * Vancomycin-intermediate Staphylococcus aureus (VISA) * Pseudomonas aeruginosa * Vancomycin-resistant Enterococcus (VRE) * Acinetobacter baumanii * Stenotrophomonas maltophilia * Carbapenem-resistant Enterobacteriaceae (CRE) * Extended-spectrum beta lactamase-producing gram-negative bacilli 4. Causative pathogen not sensitive to choice of initial empiric antibiotic 5. Antibiotic therapy for \> 5 of the last 10 days preceding VAP diagnosis 6. Septic shock, defined as evidence of tissue hypoperfusion after adequate volume expansion, due to infection, and requiring \> 1 vasopressor (17) 7. Current or recent (within 30 days) use of immunosuppressive medications 8. LOS \> 72 hours at a transferring facility 9. Pregnancy or lactation 10. Legal arrest or incarceration 11. Moribund state in which death is imminent 12. ECMO (Extracorporeal membrane oxygenation) 13. Extubation prior to randomization
