NCT06488794

Brief Summary

The goal of this clinical trial is to learn if nebulized colistimethate sodium can prevent pneumonia in ventilated children. The main question it aims to answer is:

  • Does nebulized colistimethate sodium lower the number of times participants develop ventilation associated pneumonia? Researchers will compare nebulized colistimethate sodium to a placebo (a look-alike substance that contains no drug) to see if nebulized colistin works to prevent ventilation associated pneumonia in children. Participants will:
  • Take nebulized colistimethate sodium or a placebo twice a day for a maximum of 7 days.
  • Will be followed to check for pneumonia occurrence while they are on mechanical ventilation.

Outcome Measures

Primary Outcomes (1)

  • Incidence of Ventilation Associated Pneumonia

    Primary outcome will be the incidence of a first episode of ventilation associated pneumonia from randomization to day 28. Incidence will be calculated as the ratio of the number of patients experiencing a first VAP episode divided by the number of randomized patients

    From randomization to 28 days post-randomization

Secondary Outcomes (7)

  • Incidence of Ventilation Associated Tracheobronchitis

    From randomization to 28 days post-randomization

  • Incidence of a first episode of VAP and VAT in the subgroup of patients with tracheobronchial bacterial colonization at randomization

    From randomization to 28 days post-randomization

  • Number of days spent on mechanical ventilation from randomization to day 28

    From randomization to 28 days post-randomization

  • Number of days without systemic antibiotics from randomization to day 28

    From randomization to 28 days post-randomization

  • ICU stay

    From randomization to ICU discharge, up to 60 days

  • +2 more secondary outcomes

Study Arms (2)

colistin group

ACTIVE COMPARATOR

Colistin group: In the Nebulized colistimethate sodium (CMS) group, 100 000 IU/kg of CMS (equivalent to 0.96 mg/kg of colistin base), will be nebulized daily, divided into two doses. The lyophilisate of CMS will be reconstituted as follows: 2 million of IU is reconstituted in 6mL of sterile 0.9% saline. The adequate volume is then withdrawn and compleated by 0.9% saline to reach a total volume of 6 ml that is administered immediately to mechanically ventilated patients via a nebulizer until the nebulized solution container becomes empty. The nebulization is administered from day 3 of invasive mechanical ventilation, twice daily for a maximum of 7 days or until extubation (whichever occurres first). \*12500 International Units of colistimethate sodium = 1 mg colistimethate sodium = 0.4 mg of colistin base.

Drug: colistimethate sodium

Control group

PLACEBO COMPARATOR

Nebulization of 6 ml of 0.9% saline twice a day for a maximum of 7 days from day 3 of invasive mechanical ventilation will be administered via a nebulizer until the nebulized solution container becomes empty.

Drug: 0.9% Saline

Interventions

100 000 IU/kg of colistimethate sodium (equivalent to 0.96 mg/kg of colistin base) , will be nebulized daily, divided into two doses for a maximum of 7 days for eligible ventilated children starting from day 3 of mechanical ventilation.
