Modified toxicity probability interval design
WebThe TEQR design extends the well known 3+3 design to allow for: an explicit target range for the dose limiting toxicity (DLT) rate, more than 6 subjects at the maximum tolerated dose (MTD), and specification of a too-toxic rate, which closes a dose level. Web27 mei 2024 · In 2010, Ji et al 38 proposed a modified toxicity probability interval (mTPI) with improvements, including overdose protection, calibration free, and correspondence to Bayes rule. In mTPI design, an equivalence interval (pT − ε1, pT + ε2), ε1, ε2 ≥ 0 was set.

The model requires a few parameters: model <- get_tpi (num_doses = 5, target = 0.25, k1 = 1, k2 = 1.5, exclusion_certainty = 0.95) The model can be fit to outcomes in the usual way: fit <- model %>% fit ('1NNT') natural sciences bathWeb11 okt. 2024 · Under this 3 + 3 design, the MTD is the highest dose level with ≤1/6 DLT. The targeted toxicity probability at MTD is in the range of 17–33%.
