Antibiotics fail to show benefit for ventilator lung infection in terminated trial
NCT ID NCT03012360
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether giving antibiotics to ICU patients with a lung infection caused by a breathing tube (ventilator-associated tracheobronchitis) could stop it from turning into pneumonia. About 100 critically ill adults on ventilators took part. The trial was stopped early, and the results did not clearly show that antibiotics helped prevent pneumonia.

Inclusion Criteria: * All adult patients hospitalized in the ICU with a first episode of VAT diagnosed \>48 hours after starting invasive mechanical ventilation are eligible for this study. VAT is defined using the following criteria: 1. absence of new infiltrate on chest X ray 2. two of the three following conditions: fever \> 38.5 °C or \<36.5, leucocyte count \> than 12 000 cells per μL or \<than 4000 cells per μL purulent tracheal secretions 3. and positive tracheal aspirate (≥105 cfu/mL) Exclusion Criteria: * long-term tracheostomy at ICU admission * patients who develop VAP before VAT * patients already receiving antibiotics active against all the microorganisms responsible for VAT * severe immunosuppression * pregnancy or breastfeeding * patients \<18 years * patients already included in another study, with potential interaction with the primary objective of the current study * known resistance to imipenem and ciprofloxacin of bacteria responsible for VAT * treatment limitation decisions * moribund patients (likely to die within 24 h) * allergy to any of study drugs: hypersensitivity to any carbapenem, severe hypersensitivity (for example anaphylactic reaction or severe cutaneous reaction) to any other antibiotic form beta-lactam group (such as penicillin or cephalosporin), severe hypersensitivity (for example anaphylactic reaction) to any other antibiotic from beta-lactam group (penicillin, monobactam or carbapenem), hypersensitivity to quinolones
