Inhaled Tobramycin for Bronchopulmonary Dysplasia
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores the use of inhaled tobramycin, an antibiotic solution for inhalation, to aid very preterm infants with bronchopulmonary dysplasia (BPD) who require mechanical ventilation. Researchers are testing various doses to determine which is safe and potentially effective against specific bacterial lung infections. The trial includes several groups receiving different doses and one group observed without treatment. Infants born before 32 weeks with specific bacterial lung infections and on mechanical ventilation might be suitable candidates. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering a unique opportunity to be among the first to receive this new treatment.
Will I have to stop taking my current medications?
Participants must stop taking any systemic antibiotics and nephrotoxic medications (except diuretics) within 7 days and 48 hours before enrollment, respectively.
Is there any evidence suggesting that this treatment is likely to be safe for humans?
Research has shown that inhaled tobramycin has been studied for safety in very preterm infants with bronchopulmonary dysplasia (BPD). Tobramycin, an antibiotic, can be inhaled to directly target the lungs.
Previous studies have found that inhaled tobramycin is generally well-tolerated in similar groups. "Well-tolerated" means that most patients did not experience serious side effects. Some side effects, like coughing or a sore throat, have been reported, but these are uncommon.
As this is a phase 1 trial, the main goal is to assess the treatment's safety and how the body processes it. In this phase, small doses are tested to identify any negative effects. While some evidence suggests that inhaled tobramycin is safe, the trial is still in early stages to fully confirm its safety.
In summary, inhaled tobramycin appears promising for safe use, but more data is needed to confirm this for preterm infants with BPD. Researchers will closely monitor participants to ensure their safety throughout the trial.12345Why are researchers excited about this trial's treatment?
Researchers are excited about inhaled tobramycin for bronchopulmonary dysplasia because it offers a unique delivery method compared to current options, which primarily involve systemic antibiotics or supportive care. Tobramycin is given directly through inhalation, potentially allowing higher local concentrations in the lungs while minimizing systemic side effects. This method could lead to more effective treatment with a quicker response time, as the medication targets the lungs directly where the inflammation occurs. Additionally, by using inhalation, there's hope for better tolerability and reduced risk of drug resistance compared to oral or intravenous antibiotics.
What evidence suggests that inhaled tobramycin could be an effective treatment for bronchopulmonary dysplasia?
Research has shown that inhaled tobramycin might help very preterm infants with bronchopulmonary dysplasia (BPD), particularly those with harmful lung bacteria. Early studies indicate that inhaled tobramycin targets these bacteria directly in the lungs, potentially improving breathing and lung health. This trial tests different doses of inhaled tobramycin to determine the safest and most effective dose. Previous patients demonstrated that tobramycin can be well-tolerated at various doses. The goal is to directly treat lung infections, potentially reducing the need for other treatments and improving outcomes for these infants.15678
Are You a Good Fit for This Trial?
This trial is for very preterm infants born before 32 weeks with Bronchopulmonary Dysplasia (BPD) on mechanical ventilation and a recent tracheal culture positive for certain bacteria. Infants must be at least 36 weeks postmenstrual age, without cancer, significant hearing loss in the family, kidney or liver disease, large endotracheal tube leaks, known drug intolerance or recent use of systemic antibiotics.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- Tobramycin solution for inhalation
Trial Overview
The study tests four escalating doses of inhaled tobramycin in these infants to check tolerability and effectiveness against Gram-negative bacterial infections. It's an open-label phase 1 trial where each infant receives one dose level to gather initial data on how the drug works and its safety.

Treatment groups
Experimental Treatment
Active Control
The phase 1 trial will begin with a dose of 78mg. All treatment arms will administer study drug every 12 hours for up to 14 days (28 doses). Up to 6 infants in this arm will receive the 78mg dose of tobramycin solution for inhalation administered via vibrating mesh nebulizer. During the trial, infants in each treatment arm will undergo blood and tracheal aspirate sampling and respiratory mechanics measurements at pre-specified time points to assess dose safety and potential efficacy. Continuous pulse oximetry monitoring for the duration of the trial will also occur. Clinical data will also be recorded daily throughout the trial in all participants.
If tolerability is demonstrated in the 216mg treatment arm following the 3+3 trial design, up to 6 infants will then be enrolled and receive 150mg of tobramycin solution for inhalation every 12 hours. The same monitoring procedures will be performed in this treatment arm as in the prior.
If tolerability is demonstrated in the 150mg treatment arm following the 3+3 trial design, up to 6 infants will then be enrolled and receive 150mg of tobramycin solution for inhalation every 12 hours. The same monitoring procedures will be performed in this treatment arm as in the prior.

Enrolled infants who are eligible to participate in the phase-1 trial may be enrolled in an untreated observational cohort at parental discretion. This cohort will undergo collection of clinical and respiratory mechanics data for 14 days after enrollment but will not receive the study drug.
