Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Prospective, randomized 1:1, open-label study to assess the microbiological cure and pharmacokinetics (PK), safety and efficacy of nebulized Aztreonam lysine (75 mg dose) each 8 hr during 5 days in ventilated patients heavily colonized by Gram-negative bacteria. It is planned to include a total of 20 ventilated patients heavily colonized. Only ten of them (active group) will receive 5 days of treatment with nebulized AZLI.The control group will not receive treatment.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
To compare the microbiological cure at day 5 of treatment and the incidence of Gram-negative IVAC between 7th and 10th days after last dose in patients heavily colonized by Gram-negative bacteria treated with nebulized AZLI vs. no treatment.
The secundary objective of this study are:
1. Safety and tolerability of AZLI administered during 5 days in adults patients under mechanical ventilation heavily colonized by Gram-negative bacteria
2. The pharmacokinetic profile in endotracheal aspirate (EA) or bronchoalveolar lavage (BAL).
3. The plasma levels of nebulized AZLI in patients under mechanical ventilation heavily colonized by Gram-negative bacteria.

RANDOMIZED
PARALLEL
Patients assigned to study group will receive nebulized Aztreonam lysine (AZLI 75 mg-dose) three times /day during 5 days by mean of the ultrasonic nebulizer (Aeroneb solo®) plus Combihaler® spacer adapted of the ventilator. All patients will be on conventional volume-control ventilator setting during the antibiotic therapy. Systemic antibiotics will not be used in any patient. If the attending physician saw the need to administer intravenous antibiotics after the patient has entry in the study, this patients should be removed from the study

Aztreonam lysine
nebulization
Aerogen Solo
Aerogen's vibrating mesh technology, available within the Aerogen® Solo has been adopted for use of conventional mechanical ventilation. Aerogen Solo utilizes active vibrating mesh technology, where energy applied to the vibrational element, causes vibration of each of the 1000 funnel shaped apertures within the mesh. The mesh acts as a micropump drawing liquid through the holes producing a low velocity aerosol optimized for targeted drug delivery to the lungs. According our study (Rodriguez A et al , Expert Opin Drug Deliv. 2017 Dec;14(12):1447-1453) Aeroneb Solo showed an excellent aerosol delivery profile for Aztreonam lysine (AZLI) in an in vitro model of MV with short drug delivery time.
CombiHaler
The inhalation chamber CombiHaler™ spacer for mechanical ventilation and critical care (ICU) allows using both a vibrating mesh nebulizer such as Aeroneb ™, and a pMDI. It saves 50% of the nebulized drug when used in invasive ventilation. The inhalation chamber CombiHaler® is integrated on a circuit of a breathing device in invasive ventilation in particular for connexion of an Aeroneb® Pro or an Aeroneb® Solo. According our study (Rodriguez A et al , Expert Opin Drug Deliv. 2017 Dec;14(12):1447-1453) a better aerosol delivery performance (30%) was obtained using the Conbihaler spacer.
