Still ethical to randomize and follow? Analyses of the accumulating study data are performed at pre-planned time points within the trial, can be performed in a fully blinded or unblinded manner, and can occur with or without formal statistical hypothesis testing . In traditional clinical trials, key elements such as primary endpoint, clinically meaningful treatment difference, and measure of variability are pre-specified during planning in order to design the study.

The adaptive design is heavily rooted in simulations . These are expanded on and re-run until investigators and trial statisticians are confident that the likely benefits of the adaptive design substantially outweigh the potential risks. Based on wide-ranging research and expert interviews, the report offers the industry critical and timely insight into how to address these new priorities in practical, strategic ways. 7.�1�Z�������7Q�q�]������O�+.o�P�Jg�b����e��!&- C�+p�t_��q8`��8_���ю�"^Q������E 5�R�>8;���������_�
