Integrating the escalation and dose expansion studies into a unified Phase I clinical trial.

ABSTRACT: We focus on Phase I dose finding studies as they are currently undertaken. The design and analysis of these trials have changed over the last years and, in particular, it is now rare for a Phase I study to not include one or more dose-expansion cohorts (DEC). It is common to see DEC involving several hundred patients, building on an initial dose escalation study that may have no >20 to 30 patients. There has been recent focus by researchers on the design of DEC and the analysis of DEC data. It is reasonable to explicitly account for the uncertainty in the estimation of the MTD, the dose upon which the whole of the DEC is currently based. In this paper, we focus on the dose escalation phase prior to the DEC, with the purpose of adapting it to the needs of DEC. Specifically, before beginning
