In this episode of "In the Interim…", Dr. Scott Berry and Dr. Kert Viele examine response-adaptive randomization (RAR) in clinical trials, dissecting its statistical rationale, common criticisms, and implementation challenges.

In Episode 66 of "In the Interim...", Dr. Scott Berry and Dr. Kert Viele tackle one of clinical trial design's most controversial topics: Response-Adaptive Randomization (RAR).

When does RAR strengthen trials, and when does it fall short? The team breaks down:

● Why two-arm trials rarely benefit from RAR

● How multi-arm dose-finding studies gain power through adaptive allocation

● Real-world examples including lecanemab's Alzheimer's trial and the ICECAP cardiac arrest study

● The operational challenges of implementation

RAR may not be a universal solution, but rather a precise tool for specific scenarios. When used correctly in multi-arm trials, it treats patients better while generating stronger evidence. When misapplied, it reduces statistical power and introduces bias.
