In adaptive clinical trials, the conventional end-of-trial point estimate of a treatment effect is prone to bias, that is, a systematic tendency to deviate from its true value. As…
Bayesian sample size determination in basket trials borrowing information between subsets
Haiyan Zheng, Michael J. Grayling, Pavel Mozgunov +2
Basket trials are increasingly used for the simultaneous evaluation of a new treatment in various patient subgroups under one overarching protocol. We propose a Bayesian approach t…
Backfilling Cohorts in Phase I Dose-Escalation Studies
Helen Barnett, Oliver Boix, Dimitris Kontos +1
The use of `backfilling', assigning additional patients to doses deemed safe, in phase I dose-escalation studies has been used in practice to collect additional information on the…
Dose Finding Studies for Therapies with Late-Onset Safety and Efficacy Outcomes
Helen Barnett, Oliver Boix, Dimitris Kontos +1
In Phase I/II dose-finding trials, the objective is to find the Optimal Biological Dose (OBD), a dose that is both safe and efficacious that maximises some optimality criterion bas…
Online error control for platform trials
David S. Robertson, James M. S. Wason, Franz König +2
Platform trials evaluate multiple experimental treatments under a single master protocol, where new treatment arms are added to the trial over time. Given the multiple treatment co…
