His methodological research inte rests include decision-making in clinical trials with multiple outcomes\, incorporating external data into clinical trial analyses and data monitori ng\, and adaptive design in general. His collaborative research has largel y been in cardiology\, oncology and behavioral science. During the past tw o years\, he has devoted much effort to help design and manage data coordi nation for clinical trials evaluating therapeutics for Covid-19. That\, an d raising two wonderful but exhausting young children with his spouse.\n\n \nI will discuss my experiences coordinating two recent clinical trials in out-of-hospital cardiac arrest that used Bayesian response adaptive rando mization designs\, and present some methodological innovations to improve implementation and understand the potential benefit these designs offer. I will discuss the ACCESS trial (Clinicaltrials.gov ID: NCT03119571)\, whic h sought to compare the efficacy of two standards or care: direct admissio n to the cardiac catheter laboratory versus the ICU\; and the ARREST trial (NCT03880565)\, which sought to evaluate the efficacy of in-transit ECMO- facilitated resuscitation versus standard Advanced Cardiac Life Support (A CLS) resuscitation. My experiences with these trials motivated methodologi cal research into alternative prior choices and randomization techniques t hat improve type I error control and reduce the risk of enrolling a substa ntial proportion of participants to an inferior treatment arm. Building up on this research\, we proposed and investigated comparing a set of potenti al designs in terms of the expected number of failures among the cohort mo st acutely affected by the choice of design\; namely\, persons who would p articipate in the trial if it were open to enrollment at the time they bec ome eligible. I plan to discuss the details and take-aways from this line of research.\n\nZoom - Please contact: admincoord.eboh [at] mcgill.ca\n\n  \n DTSTART:20220216T203000Z DTEND:20220216T213000Z SUMMARY:Thomas Murray\, PhD (University of Minnesota) URL:/mathstat/channels/event/thomas-murray-phd-univers ity-minnesota-337584 END:VEVENT END:VCALENDAR
