The purpose of this study is to determine if the combination of late doses of Infasurf with inhaled nitric oxide will interact to improve the surfactant function and thus the respiratory status and outcome of treated infants.

Primary Outcome Measures:
  • SP-B Content [ Time Frame: One day after dose ]
    SP-B Content is the surfactant protein B found in terms of percentage of phospholipid measured one day after surfactant or sham dose.

Secondary Outcome Measures:
  • Alive Without BPD at 36 Weeks Post Menstrual Age [ Time Frame: 36 Weeks Post Menstrual Age ]
    Alive without need for oxygen at 36 weeks post menstrual age.

Enrollment: 85
Study Start Date: January 2008
Study Completion Date: December 2012
Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Treatment Surfactant (Infasurf) ONY, NY
Patients receive inhaled nitric oxide and scheduled doses of Infasurf on study days 0, 3, 7, 10, and 14, if infant remains ventilated.
Drug: Infasurf (ONY Inc.)
Infasurf 3ml/kg will be given to infants on study days 0, 3, 7, 10, and 14, if remains intubated.
Other Name: Infasurf
Placebo Comparator: Sham (no treatment)
Infants receiving inhaled nitric oxide will receive Sham (no treatment) on study days 0, 3, 7, 10, and 14, if infant remains ventilated.
Drug: Sham
Sham instillation (no treatment) will be given to study infants on days 0, 3, 7, 10, and 14, if remains intubated.
Other Name: Air

Detailed Description:
Surfactant dysfunction my contribute to the development of bronchopulmonary dysplasia (BPD) in persistently ventilated preterm infants. We conducted a multi-center, randomized, blinded pilot study to assess the safety and efficacy of late administration of surfactant (Calfactant - high in protein B) in combination with prolonged inhaled nitric oxide in preterm infants < 1000 grams birthweight (BW). Calfactant is one of several types of exogenous surfactant. Calfactant has the highest % of surfactant protein B of the different types.
