WebJun 13, 2024 · Bayesian Optimal Interval (BOIN) designs are a class of model-assisted dose-finding designs that can be used in oncology trials to determine the maximum tolerated dose (MTD) of a study drug based on safety or the optimal biological dose (OBD) based on safety and efficacy. BOIN designs provide a comp … WebThe BOIN design allows the cohort size to vary from one cohort to another. 2.1 Trial design To design the trial, we only need to run the function get.boundary() to get the dose escalation and deescalation boundaries, which are all we need to run the trial.
