Webb23 okt. 2024 · The modified toxicity probability interval (mTPI) design was introduced by @Ji2010. As the name suggests, it is a modification of the earlier TPI design, introduced by @Ji2007. mTPI is one of a series of dose-finding trial designs that works by partitioning the probability of toxicity into a set of intervals. Webbsimilar to the traditional “3+3” design. Compared to the well-known continual reassessment method, the BOIN design yields comparable average performance to select the MTD, but has a substantially lower risk of assigning patients to subtherapeutic and overly toxic doses. We apply the BOIN design to two cancer clinical trials.
