WebOct 23, 2024 · Introduction. 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.
