Primary Outcome Measures:
  • Number of Participants With Respiratory Distress Syndrome [ Time Frame: 24 hours ]

Secondary Outcome Measures:
  • Area Under the Curve (AUC) for Fraction of Inspired Oxygen (FiO₂) [ Time Frame: 0.5, 1, 2, 4, 6, 12, 18, 24, 36, 48, 60, 72 hours ]
    AUC for FiO₂calculated using the trapezoidal rule. Missing data imputed using last observation carried forward

  • Arterial Alveolar (a/A) O₂Ratio [ Time Frame: 72 hours ]
    a/A ratio is a relative way to judge the lungs ability to transport O₂. It compares the partial pressure of O₂in the alveoli (A) to the partial pressure of O₂in the artery (a). It is calculated by dividing the partial pressure of O₂in the artery, abbreviated PaO2, by the partial pressure of O₂in the alveoli using the alveolar gas equation, abbreviated PAO2. A value of 0.80 or above is normal, a value of 0.60 or below may be incompatible with spontaneous breathing, and a value below 0.22 indicates severe lung disease.

  • Time to Meet Failure Criteria [ Time Frame: Through 28 days ]
    Failure criteria defined as rescue with bolus surfactant and mechanical ventilation

  • Number of Participants With Bronchopulmonary Dysplasia (BPD) [ Time Frame: 28 days ]
  • Number of Participants Alive and Without BPD [ Time Frame: 28 days ]
  • Number of Participants With Intraventricular Hemorrhage (IVH)/Periventricular Leukomalacia (PVL) [ Time Frame: 28 days ]
  • Number of Participants With Patent Ductus Arteriosus (PDA) [ Time Frame: 28 days ]
  • Number of Participants With Necrotizing Enterocolitis (NEC) [ Time Frame: 28 days ]
  • Number of Participants With Pulmonary Hemorrhage [ Time Frame: 28 days ]
  • Number of Participants With Acquired Sepsis [ Time Frame: 28 days ]
  • Incidence of Mortality [ Time Frame: 28 days ]
  • Number of Participants With Air Leak [ Time Frame: 28 days ]

Arms Assigned Interventions
Experimental: Regimen 1 Drug: Aerosolized lucinactant
Aerosolized lucinactant via nCPAP over 3 hours. Up to 3 retreatments will be allowed over a 48 hour period with each retreatment separated by at least 3 hours.
Other Name: KL₄Surfactant
Experimental: Regimen 2 Drug: Aerosolized lucinactant
Aerosolized lucinactant via nCPAP over 3 hours. Up to 3 retreatments will be allowed over a 48 hour period with each retreatment separated by at least 1 hour.
Other Name: KL₄Surfactant

Detailed Description:
Use of a device in the early treatment of RDS that permits the effective aerosolization of an exogenous surfactant that also allows for the simultaneous delivery of continuous positive airway pressure would permit the delivery of surfactant to the distal airways without intubation. This approach could reduce the frequency of severity of the adverse events relative to endotracheal intubation and surfactant administration via bolus.
