Adaptive clinical trials use existing facts to design the trial, and then use interim benefits to switch the trial mainly because it proceeds.

If the Most important goal of the clinical trial is efficiency or efficacy, the scientific validity of the comparison of the new procedure to some regular is determined by the comparability with the groups that obtain the experimental and Regulate treatment plans. Randomization of patients to two or more treatment method groups is the key tool to ensure the comparability of samples, at the least on average. Consequently, it can be of utmost importance that the data from Every single clinical trial be analyzed according to the intent-to-address basic principle, which dictates that every subject’s data be included in the remedy group to which he or she is randomized.
