The phase-II trial was successful in reducing the burden of cerebral hypoxia to less than half. Therefore we now want to conduct a large pragmatic trial involving 1500 infants and the collaboration of 50-100 neonatal units. The purpose is to examine if this can reduce the risk of death or severe brain injury at 36 weeks of age from about 34% in the control group to about 26% in the experimental group. The secondary outcome is reduced risk of moderate-to-severe neurodevelopmental deficit at 2 years of age.
First we formed a group of 93 neonatal units in 17 European countries and applied to the Horizon2020 research programme.
This call received applications for 113 projects in stage-1 of which 36 were allowed to submit an application to stage-II – among these SafeBoosC-III. But we were not funded.
Next we formed a consortium with 10 national partners and applied to the Irish Heath Research Board in 2016. Again we were shortlisted, but in March 2017 we learned that we were not funded.
We then considered a cluster randomized design. The SafeBoosC intervention is complex: Monitoring of cerebral oxygenation by NIRS from 3 hours after birth until 72 hours and adequate implementation of the treatment guideline whenever cerebral oxygenation drop below the threshold. This means that many clinical staff members are involved and therefore a cluster design would be more efficient in terms of training and equipment. Also, since the phase-III trial is pragmatic, only outcomes that are routinely reported to neonatal networks are used, such as mortality, major brain injury as detected by routine cerebral ultrasound, and other major neonatal morbidities. But such a design would require the participation of approximately 140 NICUs. Furthermore, the research ethics is less clear, since parental choice would be reduced.
In September 2017 we applied to the NovoNordicFoundation for a trial planning to involve 50 NICUs to enroll 1600 infants in a pragmatic, individually randomized clinical trial over a period of two years. This was not granted.
Current plans are to apply for funding of the trial center costs.
