IMP delivery

Box of 4 ampoules containing Baby-OSCAR IMP

Trial medication is on its way to the next site due to open for recruitment, Jessop Wing, Sheffield.

These tiny ampoules contain either Ibuprofen 5mg/mL or Placebo Solution. As a masked, randomised placebo-controlled parallel group trial it is important that we do not know what is in the ampoules. This ensures that there is no bias when interpreting the study results, meaning that the trial is conducted and analysed with the highest integrity.

The story so far...

Since re-launching at the start of the month, our large team of researchers across the country have been busy, with 6 sites now open and another 10 to open in April. We are extremely grateful for the valuable work that these consultants and nurses do in looking after the babies in their care. We have had four new babies enrolled in the Baby-OSCAR Trial since re-launching, and our thanks also goes out to these families.

No. 1 non-pilot site to recruit!

With four participants enrolled so far, Bradford has recruited ‘the first baby from a non-pilot site’.  All the researchers are grateful to families, who help to improve knowledge and understanding by taking part in clinical trials and improve the care of babies in the future.

Mandatory Closure versus Nonintervention

A comment from Prof Samir Gupta

Chief Investigator for the Baby-OSCAR Trial

This retrospective cohort study compared two time periods of different approaches to PDA. In period I, all large PDA (more than 2 mm) were closed medically at a median age of 7 days and/or surgically at a median age of 12 days. In period II no treatment was offered.

The data suggests once PDA is symptomatic, it does not affect outcomes whether one closes a PDA or not. Investigators report higher incidence of BPD in period I when PDA was closed surgically (in ~80% babies). This could be the effect of surgery as this association has been reported earlier. It is surprising that, unlike previous reports, persistent PDA in this study was not associated with increased odds of death or NEC, but with significantly less BPD. The medication used in this study was indomethacin that is now known to have a poor side effect profile as compared to ibuprofen. The limitations of this study are that it is a single site, retrospective observational study in two time periods and uses indomethacin for medical treatment.

The results of this study, however, support the Baby-OSCAR protocol that a symptomatic PDA, if diagnosed after 7 days of age in ventilator dependent babies, does not necessarily benefit from medical and/or surgical treatment, and hence by limiting rescue or open-label treatment, we do not cause harm.
