Study Description

Brief Summary:

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.

Condition or disease	Intervention/treatment	Phase
Respiratory Distress Syndrome of Prematurity (Surfactant Dysfunction) Bronchopulmonary Dysplasia	Drug: Infasurf (ONY Inc.) Drug: Sham	Phase 3

Detailed Description:

Surfactant dysfunction may contribute to the development of bronchopulmonary dysplasia (BPD) in persistently ventilated preterm infants. The investigators 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.

Arms and Interventions

Arm	Intervention/treatment
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

Outcome Measures

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.
