UnifiedDoseFinding:Dose-Finding Methods for Non-Binary Outcomes
In many phase I trials, the design goal is to find the dose associated with a certain target toxicity rate. In some
trials, the goal can be to find the dose with a certain
weighted sum of rates of various toxicity grades. For others,
the goal is to find the dose with a certain mean value of a
continuous response. This package provides the setup and
calculations needed to run a dose-finding trial with non-binary
endpoints and performs simulations to assess design’s operating
characteristics under various scenarios. Three dose finding
designs are included in this package: unified phase I design
(Ivanova et al. (2009) <doi:10.1111/j.1541-0420.2008.01045.x>),
Quasi-CRM/Robust-Quasi-CRM (Yuan et al. (2007)
<doi:10.1111/j.1541-0420.2006.00666.x>, Pan et al. (2014)
<doi:10.1371/journal.pone.0098147>) and generalized BOIN design
(Mu et al. (2018) <doi:10.1111/rssc.12263>). The toxicity
endpoints can be handled with these functions including
equivalent toxicity score (ETS), total toxicity burden (TTB),
general continuous toxicity endpoints, with incorporating
ordinal grade toxicity information into dose-finding procedure.
These functions allow customization of design characteristics
to vary sample size, cohort sizes, target dose-limiting
toxicity (DLT) rates, discrete or continuous toxicity score,
and incorporate safety and/or stopping rules.
