" Study of the Benefit of Nebulized Amikacin in the Treatment of Gram-negative Bacillus Pneumonia Acquired During Mechanical Ventilation in Patients Receiving Extracorporeal Membrane Veno-arterial Oxygenation "
France26 participantsStarted 2026-08-10
Plain-language summary
Pneumonia are the most frequent infectious complication in patients on Extracorporeal Membrane Oxygenation Veno-arterial (ECMO-VA), with a treatment failure rate of around 40%, even though antibiotic therapy is tailored to the germs identified. One hypothesis to explain this particularly high failure rate is the reduced pulmonary blood flow associated with ECMO offloading of the heart. Although there are no data to date on the pulmonary penetration of antibiotics in patients undergoing VA-ECMO, this phenomenon of pulmonary hypoperfusion could contribute to altering the alveolocapillary diffusion of antibiotics, thereby reducing their concentration in the pulmonary parenchyma.
Our hypothesis is that amikacin nebulization could increase bacterial clearance and, ultimately, limit treatment failure or recurrence of gram-negative bacilli (GNB) pneumonia in patients undergoing VA-ECMO.

Inclusion criteria
. Patient 18 years or older
. Circulatory assistance by veno-arterial ECMO for at least 24 hours prior to documentation of pneumonia
. Invasive mechanical ventilation
. Diagnostic suspicion of pneumonia based on evocative criteria (presence of at least 2 of the following criteria): fever (superior to 38. 5°C), hypothermia (inferior to 36.0°C), hyperleukocytosis (superior to 11 × 10\^9 l-1) or leukopenia (inferior to 4 × 10\^9 l-1), purulent tracheobronchial secretions, altered oxygenation with need to increase FiO2 on ECMO or ventilator for the same SaO2 or PaO2 target, new or persistent pulmonary infiltrate(s) on chest x-ray in bed, or image suggestive of pneumonia on chest CT, or consolidation of appearance suggestive of an infectious origin on pulmonary ultrasound.
. And microbiological confirmation of Gram-negative ventilator-associated pneumonia by quantitative culture on bronchoalveolar lavage (BAL, significance threshold superior to 10\^4 CFU/ml) or protected distal sampling (PDP, significance threshold superior to 10\^3 CFU/ml).
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
