Concurrent Session 4D - Maternal Fetal Medicine
Professor William Tarnow-Mordi graduated with first class Honours in medicine in Cambridge, UK, and completed specialist neonatal training in Oxford. He moved from Dundee to Sydney in 1999 to become Director of Neonatal and Perinatal Trials at the NHMRC Clinical Trials Centre. He leads a research program in larger-scale RCTs with successful funding from NHMRC for INIS,1 BOOST-II,2 APTS,3 LIFT, LEAP, TORPIDO-2 and ESPRESSO and from the Australian Medical Research Future Fund for WHEAT- all major phase III trials that have had or will have a significant influence on international clinical practice. He was awarded the Australian Clinical Trials Alliance (ACTA) Clinical Trial of Year 1st Runner Up (2017) for BOOST-II; ACTA Trial of the Year (2018) for APTS and co-awarded the ACTA Consumer Award (2019) with Melinda Cruz, a parent investigator, for TORPIDO3060.
He will draw lessons from the (many) limitations of perinatal trials and meta-analyses addressing how to reduce mortality or morbidity with antenatal antibiotics through the ORACLE trials,4,5 aspirin through the PARIS COllaboration,6,7 delayed clamping of the umbilical cord,8 targeting safe oxygen saturation levels in preterm babies9 and – most recently – by giving women in labour at term oral Sildenafil (Viagra) to reduce Caesarean section and emergency instrumental birth for fetal distress through the RIDSTRESS Phase II trial.10 Can we improve disability or morbidity-free survival in a new generation of international trials which can enrol tens of thousands of participants, ten times faster, a tenth of current costs? He will invite the critical engagement and wholehearted support of Canadian colleagues, firstly in considering participation in iSEARCH - a proposed series of international Phase III megatrials of Viagra in term labour - and secondly in helping to build a global initiative to transform healthcare - starting with perinatal medicine - by embedding key trials into routine care through the ENRICH (Embedding Necessary Research In Culture and Health) Initiative, coordinated through the ALPHA Collaboration for Advancing Large, collectively Prioritized trials of Health outcomes Assessment.
