The purpose of this study is to see if a medication called Curosurf can reduce the length of time that small premature babies with Respiratory Distress Syndrome (immature lungs) or RDS, stay on the ventilator, as compared to the standard medication called BLES. Curosurf is a medication that is already used in other countries around the world but not yet in Canada.

Babies born under 30 weeks of gestation frequently need respiratory support after birth, including being placed on a breathing machine or respirator. The most common reason is Respiratory Distress Syndrome (RDS) whereby immature lungs don't produce enough surfactant, a soapy like substance that helps the air sacs open and close. Our current standard treatment is a surfactant called BLES. Curosurf contains more active ingredient per volume therefore the amount is smaller. The investigators hypothesize that babies who receive Curosurf will be able to be removed from the ventilator sooner.

Babies in this study will have a 50/50 chance of receiving either Curosurf or BLES and the investigators will monitor their progress during their Neonatal Intensive Care Unit admission.

The study is taking place in Canada. The goal is to enroll 88 babies. There are no extra tests (blood tests or X-Rays) or return visits to the hospital for the purposes of this study.

Primary Outcome Measures:
  • The primary objective of the study is to compare between the two groups, the number of subjects alive and extubated at 48 hours post surfactant administration. Extubation [ Time Frame: 48 hours ] [ Designated as safety issue: Yes ]
    1. rate on ventilator ≤40 per minute and
    2. mean airway pressure ≤ 10 cm H20 and
    3. fi02 ≤ 30%

Secondary Outcome Measures:
  • To compare the duration of respiratory support, extubation failure rates, need for additional surfactant doses, adverse events (during and following administration), survival and pulmonary morbidities during hospital admission between the two groups. [ Time Frame: 36 weeks GA ] [ Designated as safety issue: Yes ]
    1. Extubation failure

  • Curosurf-01 [ Time Frame: 36 weeks GA ] [ Designated as safety issue: Yes ]
    2. Duration of first intubation (in hours/days)

  • Curosurf-01 [ Time Frame: 36 weeks GA ] [ Designated as safety issue: Yes ]
    3. Total duration of respiratory support (ventilator and nCPAP) and total number of days of oxygen requirement

  • Curosurf-01 [ Time Frame: 36 weeks GA ] [ Designated as safety issue: Yes ]
    4. Number of doses of surfactant received

  • Curosurf-01 [ Time Frame: 36 weeks GA ] [ Designated as safety issue: Yes ]
    5. Adverse events during or after administration of surfactant

  • Curosurf-01 [ Time Frame: 36 Weeks GA ] [ Designated as safety issue: Yes ]
    6. Bronchopulmonary dysplasia, defined as oxygen or respiratory support requirement at 36 weeks corrected GA

  • Curosurf-01 [ Time Frame: 36 weeks GA ] [ Designated as safety issue: Yes ]
    7. Mortality prior to discharge

Estimated Enrollment: 88

Estimated Primary Completion Date: June 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Curosurf (Group 1)
Surfactant(Curosurf in this arm) is given for treatment of RDS after the diagnosis has been made by the Neonatologist. The treatment dose for Curosurf® is 2.5 ml/kg (200mg/kg) for the first dose and 1.25 ml/kg (100mg/kg) for repeat doses, given by endotracheal method. There is a maximum of 3 doses in the study.
Drug: Curosurf-Group1
Maximum of 3 doses are administered to infants diagnosed with RDS.
Active Comparator: BLES (Group 2)
Surfactant(BLES in this arm) is given for treatment of RDS after the diagnosis has been made by the Neonatologist. For BLES the recommended dose is 5 ml/kg. given by endotracheal method. There is a maximum of 3 doses in the study.
Drug: BLES-group 2
Maximum of 3 doses are administered to infants with RDS
