Thanks Osama.

That's my thinking as well since the BE studies were ~ 100% in ratios and reasonably sized.
But explaining to those non-pk/bioparm management f**ls who keep asking for risk assessment BS is a challenge.

❝ What about if you start with sampling time points @ 10 min ( EMA) and not @ 5min ( FDA)?

❝ have you tried with bootstrapping to overcome the high variability in the early sampling time points?

Unfortunately the guidance asked for 5 and 10 mins and on... evaluating the data now to see if there is need to evaluate..
