Parallel Group Adaptive Designs [Two-Stage / GS Designs]
I am thinking of using two stage approach for a parallel BE study (in patients) is there an accepted procedure for sample size calculations? at stage 1 and stage 2?
Any instances where FDA accepted a two stage design methodology for calculating samples size for stage 2 after reviewing stage 1 results?
