  • Ah, the hideous memories come flooding back. The dreaded ICH E10 draft document("Choice of Control Group in Clinical Trials"), where it was abundantly clear from the get-go that "harmonisation" was never going to be possible because of the FDA's obsessive love for placebo-controlled trials even in situations where such trials were clearly highly ethically dubious. As this latter position was espoused by regulatory agencies in Europe and Canada, the gulf between their position and that of FDA was fundamentally unbridgeable. Which left those of us in the pharmaceutical industry charged with reviewing draft after interminable draft of this freaking document in a Kafkaesque no-man's land.
