The ethical benefits of adaptive clinical trials have been widely acclaimed: higher prospects for patients to be enrolled into the correct trial arm ; shorter trials for the most effective new therapies (see the early stopping outcome of the MUSEC trial) ; and enrollments commensurate with the needs of research, i.e. the last patient enrolled is not superfluous to a trial’s outcomes (e.g. according to one clinical biostatistician, “trial designs that learn more and treat better with less burden and sacrificing of patients”) .
However, the acknowledgement that ethical benefits exist is a separate question from the degree to which they exist when compared to a more traditional design.
