OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, please contact halo@digital.ox.ac.uk

Short Bio:
Charlie is a Trial Data Scientist working in the Clinical Trial Service Unit & Epidemiological Studies Unit (CTSU) at Oxford Population Health and the Data Linkage Lead for the ASCEND-PLUS trial. His work aims to develop new trial methods to streamline large-scale randomised trials that produce reliable answers, including the use of healthcare systems data to recruit and follow-up participants.
Abstract:
Large-scale randomised trials are increasingly costly and resource intensive to conduct, thus limiting the size and duration of follow-up of contemporary clinical trials. Streamlining trials by re-using healthcare systems data offers the opportunity to conduct more efficient trials at scale. In this talk Charlie will (1) present the theory behind utilising such data in clinical trials, (2) outline recent findings about how reliable healthcare systems data are in ascertaining trial outcomes; and (3) illustrate its use in the ASCEND-PLUS randomised trial of semaglutide versus placebo in people with diabetes.
