A Multi-center Trial to Determine if Curosurf® Reduces the Duration of Mechanical Ventilation in Very Preterm Infants

Phase 3

Completed

Brief Summary: 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 32 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.

Arm && Interventions

Group	Intervention	Description
Curosurf (Group 1)	Curosurf-Group1	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.
BLES (Group 2)	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.

Primary Outcome Measures

Name	Time	Method
