About this trial

This is an interventional treatment trial for Bronchopulmonary Dysplasia focused on measuring Bronchopulmonary Dysplasia, Neonates

Eligibility Criteria

undefined - 6 Months (Child)All SexesDoes not accept healthy volunteers

Inclusion Criteria

  1. Neonates with severe BPD as defined by 36 weeks post conception age and require positive pressure ventilation
  2. Infants born at less than 32 weeks post conception age
  3. Subjects may be up to 6 months corrected age
  4. On conventional mechanical ventilation for chronic lung disease for at least two days prior to enrollment
  5. On conventional mechanical ventilation at the time of enrollment and anticipated to continue for 14 days
  6. Off systemic steroids for lung disease for 72 hours (3 days) prior to T=0
  7. Hemoglobin value ≥8 g/dL: if less than 8 g/dL, transfusion is permitted. Clinical blood transfusion should be administered prior to enrollment.
  8. Parental/guardian permission (informed consent)

Exclusion Criteria

  1. Mechanical ventilation for acute disease, such as for infection or for post-operative complications
  2. Severe Pulmonary Hypertension (PAH) (pulmonary pressure greater than 2/3 systemic) as defined by either echocardiogram (ECHO), or cardiac catheterizations or a CT-Angiogram consistent with PAH within the last 3 weeks.
  3. Pneumothorax (active air leak) requiring chest tube within 72 hours of T=0
  4. Active pulmonary hemorrhage within 72 hours of T=0
  5. History of Grade III/IV interventricular hemorrhage without resolution or stability within 3 weeks of verifying eligibility
  6. Severe congenital heart disease compromising pulmonary circulation
  7. Other major congenital malformation (including but not limited to CDH) or known genetic syndromes at the discretion of the investigator
  8. Use of an investigational drug within 7 days prior to confirmation of eligibility.
  9. The clinical attending physician believes it is not in the subject's and/or parents/guardians best interest to participate in the trial.

Arms of the Study

Arm 1

Arm 2

Arm Type

No Intervention

Active Comparator

Arm Label

Usual Care (Control) Group

Perfluorooctylbromide (PFOB) Group

Arm Description

Control subjects will be treated as per standard of care for preterm infants with BPD.

Subjects in the PFOB group will be administered an initial PFOB treatment dose of 2.5 mL/kg and up to a total intra-pulmonary volume of 25 mL/kg for up to 10 days.

Outcomes

Primary Outcome Measures

Sustained oxygen desaturations for greater than ten minutes without response to increased oxygen therapy
Incidence of sustained (greater than 10 minutes) oxygen desaturation events without response to increased oxygen therapy. These incidences will be measured by a continuous non-invasive percutaneous oxygen saturation monitor.
Persistent hypotension without response to volume expansion and/or inotropic therapy
Incidence of persistent hypotension without response to volume expansion and/or inotropic therapy. Hypotension is a decrease in systolic blood pressure deemed significant by clinical staff. Measurement will be performed with a standard intensive care unit blood pressure cuff.
Change in number of major mucus plugging events
Incidence of airway obstruction of the endotracheal tube, as indicated by decreased chest movement during mechanical ventilation, need for increased ventilator pressure, and/or elevation of carbon dioxide levels in the blood. Mucus plugs are confirmed by endotracheal suctioning.
Incidence of pneumothorax or pleural effusion with PFOB
Incidence of pneumothorax in the child will be measured by transillumination of the chest and confirmed by chest x-ray.
Number of participants with sustained hypercapnia (elevated carbon dioxide in the blood, greater than 95 mmHg, for over four hours).
Hypercapnia will be measured with blood tests and/or cutaneous carbon dioxide monitor.

Secondary Outcome Measures

Change in fraction of inspired oxygen (FiO2)
Fraction of inspired oxygen is the percentage of oxygen that the patient is receiving for his or her lung disease. An FiO2 of 0.21 is room air oxygen and 1.00 is 100% oxygen. The higher the FiO2, the more severe the respiratory disease.
Change in ventilator mean airway pressure (MAP)
Mean airway pressure (MAP) is the average amount of airway pressure supplied to the lungs throughout a breath. Higher MAP indicates more severe disease.
Change in Respiratory Severity Score (MAP x FiO2)
Respiratory Severity Score (RSS) is a scale computed as the Mean Airway Pressure (MAP) multiplied by the Fraction of Inspired Oxygen (FiO2). Clinically, the scale range will often lie between 1 and 10, with higher numbers indicating more severe disease. The RSS can theoretically reach a score as high as 30-35.

5. Study Description

Brief Summary
The primary study objective is to assess the safety and feasibility of perfluorooctylbromide (PFOB) partial liquid ventilation (PLV) in infants with severe Bronchopulmonary Dysplasia (BPD).
Detailed Description
The primary study objective is to assess the safety and feasibility of perfluorooctylbromide (PFOB) partial liquid ventilation for up to ten days in infants with severe BPD as evaluated by: (1) no sustained oxygen desaturations (SpO2 ≤ 80%) for greater than ten minutes without response to increased oxygen therapy, (2) no persistent hypotension without response to volume expansion and/or inotropic therapy, (3) no major mucus plugging events (defined as events that are unresolved after two bronchoscopes), (4) no pneumothoraces or pleural effusion with PFOB, (5) and no evidence of increased carbon dioxide (CO2) retention, renal insufficiency, hyperkalemia, or metabolic acidosis.
