A cautious use of auxiliary outcomes for decision-making in randomized clinical trials
Massimiliano Russo, Steffen Ventz, Lorenzo Trippa
Clinical trials often collect data on multiple outcomes, such as overall survival (OS), progression-free survival (PFS), and response to treatment (RT). In most cases, however, stu…
Bayesian Multi-Arm De-Intensification Designs
Steffen Ventz, Lorenzo Trippa
In recent years new cancer treatments improved survival in multiple histologies. Some of these therapeutics, and in particular treatment combinations, are often associated with sev…
Integration of Survival Data from Multiple Studies
Steffen Ventz, Rahul Mazumder, Lorenzo Trippa
We introduce a statistical procedure that integrates survival data from multiple biomedical studies, to improve the accuracy of predictions of survival or other events, based on in…
Bayesian Uncertainty Directed Trial Designs
Steffen Ventz, Matteo Cellamare, Sergio Bacallado +1
Most Bayesian response-adaptive designs unbalance randomization rates towards the most promising arms with the goal of increasing the number of positive treatment outcomes during t…
