WebAug 19, 2024 · The interval 3 + 3 (i3 + 3) design is a recently proposed algorithm-based dose-finding design based on a similar decision rule with some modifications. The … WebBayesian optimal interval (BOIN) design is a model-assisted phase I dose-finding design to find the maximum tolerated dose. The hallmark of the BOIN design is its concise decision rule—making the decision of dose escalation and de-escalation by simply comparing the observed dose-limiting toxicity rate at the current dose with a pair of optimal dose …
