Parallel study as pilot for long half life drug [Design Issues]
Dear Dan,
I don't see how I can proceed with a pivtoal crossover study later. The CV (total CV) obtained from the parallel pilot study is not appropriate for estimating the crossover study sample size since one cannot extract the intraCV from the total CV.
The dilemma I have now is timing... If I go with a crossover pilot --> probably 16 day sampling and 30 day washout --> bloody long study...
If I go with parallel study then cost will be a factor... Double edge sword...
