In this episode of "In the Interim…", host Dr. Scott Berry undertakes a detailed, methodical critique of ICH-E20 draft guidance language as applied to adaptive clinical trial design.

Episode 58 of "In the Interim…" features Dr. Scott Berry dissecting regulatory “false choices” which is when adaptive trial designs are rejected in favor of unrealistic multi-trial pathways.

Scott explains how concerns about the frequency and complexity of adaptations are largely mythical. He uses concrete trial examples to demonstrate that rejecting adaptive designs tends to result in less informative, less efficient studies, not improved rigor.

Key insights:

● Myths about adaptation complexity drive misguided decisions.

● Efficiency enables essential trials that would otherwise never occur.

● False Choices: Rejecting Design A because B would be better, when B will never be run, meaning they get C, worse for all involved.

Listen now and share our experience with regulatory evaluation of adaptive trials.
