Please be advised that due to the high volume of submissions, the ANZCTR is currently experiencing delays in processing submissions from those outside of Australia and New Zealand. As the ANZCTR is funded by Australia and New Zealand, we must prioritise submissions from these countries first. International submissions should allow additional time for registration. Apologies for any inconvenience caused.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Minimally invasive surfactant therapy - delivery of exogenous surfactant to the lung via brief catheterisation of the trachea with an instillation catheter in a preterm infant who is being supported with continuous positive airway pressure (CPAP) via nasal prongs or mask. The poractant surfactant dose will be 200 mg/kg, administered over 15 - 30 seconds. Total duration of the procedure will be less than 5 minutes, followed by reinstitution of CPAP. Only a single dose will be given within the first 6 hours of life.

This intervention will be given throughout the course of the trial, which is expected to last 5 years.

Treatment: Devices
Comparator / control treatment
Continued treatment with nasal CPAP delivered by prongs or mask. This is the standard control treatment. After randomisation, infants will receive a sham treatment from a treatment team not engaged in clinical care. This will not involve removal of prongs or discontinuation of CPAP but will require setting up intubation equipment, screening the baby, testing suction unit, repositioning of the baby and changing the baby's monitoring.
Control group
Placebo

Outcomes
Primary outcome [1] 262337 0
Composite outcome of death by 36 weeks or physiological bronchopulmonary dysplasia (BPD). Physiological BPD is assessed at 36 weeks post-menstrual age, and is defined as either need for respiratory support (intubation / CPAP / high flow nasal cannula > 2 L/min) or need for FiO2 >=0.3 or failure of a room air trial conducted at 36 weeks post-menstrual age. This will be assessed by the research nurse at each centre.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Preterm infants of gestation 25 weeks 0 days - 28 weeks 6 days who fulfill the entry criteria will be enrolled once written parental consent has been obtained by the treating clinicians. The infant will be randomised by the OPTIMIST Treatment Team, after handover of care from the treating clinicians. A web-based central randomisation program will allocate infants into “surfactant via MIST” and “standard care” groups, with an allocation ratio of 1:1. Twins and higher order multiples will be randomised independently.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomisation schedule and web-based service will be provided by the Clinical Epidemiology and Biostatistics Unit at the Murdoch Childrens Research Institute. The randomisation will be in randomly permuted blocks of variable length, stratified by study centre, and by gestational age. There will be two gestational age strata; 25-26 weeks and 27-28 weeks.

Summary
Brief summary
Does administration of exogenous surfactant using a minimally-invasive technique improve outcome in preterm infants 25-28 weeks gestation treated with continuous positive airway pressure (CPAP)? A multicentre, randomised, masked, controlled trial will be conducted in inborn preterm infants 25-28 weeks gestation, aged less than 6 hours, requiring CPAP because of respiratory distress, with an FiO2 of >=0.3 and CPAP pressure 5-8. Infants randomised to surfactant treatment will receive 200 mg/kg of poractant alfa (Curosurf) administered under direct laryngoscopy using a surfactant instillation catheter, followed by reinstitution of CPAP. Controls will continue on CPAP. The intervention will be masked from the clinical team. Care thereafter will be as per usual in both groups, other than the requirement to adhere to intubation criteria. The primary outcome will be incidence of death or BPD. Secondary outcomes will include incidence of death, major neonatal morbidities (BPD, intraventricular haemorrhage, periventricular leukomalacia, retinopathy of prematurity, necrotising enterocolitis), pneumothorax and patent ductus arteriosus; need for intubation and surfactant therapy; durations of mechanical respiratory support, intubation, CPAP, intubation and CPAP, high flow nasal cannula (HFNC), oxygen therapy, intensive care stay and hospitalisation; hospitalisation cost; applicability and safety of the MIST procedure; and outcome at 2 years. The sample size will be 303/group, allowing detection of a 33% difference in the primary outcome with 90% power. The trial commenced at Royal Hobart Hospital December 2011 and Royal Women's Hospital during 2012, and will ultimately be conducted over 5 years in multiple centres nationally and overseas.
