Hi Shuanghe,

» What happens if T is BE to R under fasting and fed but T has much more food effect than R? Will "nice-to-know" become "but-now-I-know-so-you-are-fucked"?

By “much more” you mean that the 90% CI is entirely outside the 80-125% limits, right? This means only that you have to forget the idea of a hybrid application.
Everything else (CI overlapping the limits) is indecisive and would not worry me. Even if you are completely outside (T demonstrated a larger food effect than R) – since both fasting and fed passed BE – stay with the generic pathway and you should be fine.

» What's your experience from regulation perspective?

Nil – also for the “nice” case. Though the EMA stated in various conferences to welcome such a hybrid application, I haven’t seen one so far. Any experience from the members?

A central lesson of science is that to understand complex issues
(or even simple ones), we must try to free our minds of dogma and
to guarantee the freedom to publish, to contradict, and to experiment.
