%description
The rapid screening of effective and optimal therapies from large numbers
of candidate combinations, as well as exploring subgroup efficacy, remains
challenging, which necessitates innovative, integrated, and efficient
trial designs(Yuan, Y., et al. (2016) <doi:10.1002/sim.6971>). MIDAS-2
package enables quick and continuous screening of promising combination
strategies and exploration of their subgroup effects within a unified
platform design framework. We used a regression model to characterize the
efficacy pattern in subgroups. Information borrowing was applied through
Bayesian hierarchical model to improve trial efficiency considering the
limited sample size in subgroups(Cunanan, K. M., et al. (2019)
<doi:10.1177/1740774518812779>). MIDAS-2 provides an adaptive drug
screening and subgroup exploring framework to accelerate immunotherapy
development in an efficient, accurate, and integrated fashion(Wathen, J.
K., & Thall, P. F. (2017) <doi: 10.1177/1740774517692302>).
