Webb1 okt. 2024 · The 3+3 method [ 3] is the most popular algorithm-based design. Simple rules for dose-escalation make it easy to use and accessible by clinicians. Even though it is inefficient with a correct selection rate as low as 30% [ 4, 5 ], it is still widely adopted by pharmaceutical companies and authorities. Webbsimilar to the traditional “3+3” design. Compared to the well-known continual reassessment method, the BOIN design yields comparable average performance to select the MTD, but has a substantially lower risk of assigning patients to subtherapeutic and overly toxic doses. We apply the BOIN design to two cancer clinical trials.
