RegisterShorter sampling interval in pilot - Good idea? [Design Issues]
Hy!
Have a drug with "normal" half-life of some hours in the mean, but considerable variability (BOTH target params). So pilot will be huuuugh and fully replicate (planned: EU submission).
Sponsor wants to make a little cheaper by having only 24 h sampling in the pilot, but considerably longer in the pivotal trial.
Good idea? Regarding sample size estimation for the pivotal (including adjusted acceptance range for Cmax, but standard acceptance range for AUC...).
Any thoughts or numbers?
