Adaptive clinical trials use current details to design the trial, then use interim success to modify the trial because it proceeds. Modifications consist of dosage, sample sizing, drug undergoing trial, patient variety standards and "cocktail" blend.[39] Adaptive trials usually make use of a Bayesian experimental design to assess the trial's progress.
