Shotgun-2: A Bayesian phase I/II basket trial design to identify indication-specific optimal biological doses

Xin Chen, Jingyi Zhang, Liyun Jianga & Fangrong Yan
For novel molecularly targeted agents and immunotherapies, the objective of dose-finding is often to identify the optimal biological dose, rather than the maximum tolerated dose. However, optimal biological doses may not be the same for different indications, challenging the traditional dose-finding framework. Therefore, we proposed a Bayesian phase I/II basket trial design, named “shotgun-2,” to identify indication-specific optimal biological doses. A dose-escalation part is conducted in stage I to identify the maximum tolerated dose and...
