%description
The primary goal of phase I clinical trials is to find the maximum
tolerated dose (MTD). To reach this objective, we introduce a new design
for phase I clinical trials, the posterior predictive (PoP) design. The
PoP design is an innovative model-assisted design that is as simply as the
conventional algorithmic designs as its decision rules can be
pre-tabulated prior to the onset of trial, but is of more flexibility of
selecting diverse target toxicity rates and cohort sizes. The PoP design
has desirable properties, such as coherence and consistency. Moreover, the
PoP design provides better empirical performance than the BOIN and
Keyboard design with respect to high average probabilities of choosing the
MTD and slightly lower risk of treating patients at subtherapeutic or
overly toxic doses.
