A Brief Overview of Bayesian Analysis for Biostatisticians

Bayesian methods are becoming more common in clinical trials. Previously, a lack of computing in sample size software hindered the use of these methods, but improvements in the area have led to more widespread use. To examine what’s new and different about Bayesian sample size determination, we first need to consider what’s done in a traditional setting.

Dose Escalation: Quickly determine the Maximum-Tolerated Dose through Continual Reassessment Method

A key drawback of the traditional 3+3 design in dose escalation is its slow processing of data to reach the target dose. In contrast, the Continual Reassessment Method designs produce an expedited convergence to the target dose or the doses near target.
