The trial will include concurrent external cooling and control arms while adaptively incorporating historical control arm data. Bayesian group sequential monitoring will be done using a posterior comparative test based on the 60-day survival distribution in each concurrent arm. Posterior inference will follow from a Bayesian discrete time survival model that facilitates adaptive incorporation of the historical control data through an innovative regression framework with a multivariate spike-and-slab prior distribution on the historical bias parameters. For each interim test, the amount of information borrowed from the historical control data will be determined adaptively in a manner that reflects the degree of agreement between historical and concurrent control arm data. Guidance is provided for selecting Bayesian posterior probability group-sequential monitoring boundaries. Simulation results elucidating how the proposed method borrows strength from the historical control data are reported. In the absence of historical control arm bias, the proposed design controls the type I error rate and provides substantially larger power than reasonable comparators, whereas in the presence bias of varying magnitude, type I error rate inflation is curbed.<\/jats:p>","DOI":"10.1214\/20-ba1229","type":"journal-article","created":{"date-parts":[[2020,7,30]],"date-time":"2020-07-30T22:01:17Z","timestamp":1596146477000},"page":"825-844","source":"Crossref","is-referenced-by-count":4,"title":["Robust Adaptive Incorporation of Historical Control Data in a Randomized Trial of External Cooling to Treat Septic Shock"],"prefix":"10.1214","volume":"16","author":[{"given":"Thomas A.","family":"Murray","sequence":"first","affiliation":[{"name":"Division of Biostatistics, University of Minnesota, Minneapolis, MN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter F.","family":"Thall","sequence":"additional","affiliation":[{"name":"Department of Biostatistics, M.
