Episode 36, “The Saga of the Lecanemab Adaptive Phase II Trial”
Dr. Scott Berry and Dr. Donald Berry break down the Lecanemab Phase II Alzheimer’s trial—a model of flexibility and efficiency after years of failed studies in the field.
The trial applied:
● 16 interim analyses plus a final readout, all published
● Response-adaptive randomization favoring promising doses
● Adaptive sample size from 300–800 patients
● Bayesian longitudinal modeling and multiple imputation for missing data
● Pre-specified probabilistic thresholds for Phase III transition and futility
Empirical evidence and adaptive methods drove precise, data-centered decisions. This approach set a new standard for informative results and adaptability in complex drug development.
