Multicentre randomised controlled trial in preterm infants 29-32 weeks gestation on continuous positive airway pressure of the effect of minimally-invasive surfactant therapy in comparison to standard care (continuation of CPAP) on the duration of respiratory support (all hours of intubation, nasal CPAP and high flow nasal cannula).

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 surfactant dose will be 100 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 12 hours of life.

Treatment: Drugs
Intervention code [2] 269280 0
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 equipment, screening baby, repositioning baby, use of suctioning equipment and change of monitoring.
Control group
Placebo

Outcomes
Primary outcome [1] 269374 0
Duration of respiratory support, including all hours of intubation, nasal CPAP and high flow nasal cannula support (flow rate > 2 L/min). This will be assessed by the research nurse at each centre.

Mortality

During first hospitalisation
Secondary outcome [2] 279497 0
Major morbidity, defined as one or more of BPD, grade III or IV intraventricular haemorrhage, periventricular leukomalacia or retinopathy of prematurity > stage 2. Screening for intraventricular haemorrhage, periventricular leukomalacia and retinopathy of prematurity will be performed as routine care, and the results taken from the medical record.

Key exclusion criteria
1. Previously intubated, or in imminent need of intubation because of respiratory distress, apnoea or persistent acidosis.

3. Identifiable alternative cause for respiratory distress (e.g. congenital pneumonia or pulmonary hypoplasia).
4. Lack of availability of an OPTIMIST treatment team.

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Preterm infants of gestation 29 weeks 0 days - 32 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. For each trial there will be two gestational
age strata 29-30 weeks and 31-32 weeks.
