Dear Joshua!

❝ Thank you so much for your reply. I was actually referring to the USFDA.

IMHO FDA never asked for t_max. If clinically relevant ‘early exposure’ should be assessed (Guidance 2003, Section III.A.8.a.):

[…] the guidance re­com­mends use of partial AUC as an early exposure measure. We re­com­mend that the partial area be truncated at the population median of Tmax values for the re­fe­rence formulation. We also recommend that at least two quantifiable samples be collected be­fore the expected peak time to allow adequate estimation of the partial area.
