Clinical Trial Summary

Aerosol antibiotic administration offers the theoretical advantages of achieving high drug concentration at the infection site and low systemic absorption, thereby avoiding toxicity. Antibiotic aerosolization has good results in patients with cystic fibrosis, but data are scarce for patients under mechanical ventilation. 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.


Clinical Trial Description

The main objectives of this study is: 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. ;
