Multi-group studies ad nauseam [BE/BA News]
❝ ❝ FDA is organizing a webinar: A Deep Dive: FDA Draft Guidance on Statistical Approaches to Establishing Bioequivalence
❝ Wishful thinking: I hope they give clear direction (kill once for all) - the annoying center/group effect portion for BE studies conducted in one country and in homogenous population.
Get prepared. Wanjie is a tough discussant.
❝ As many times and on many platforms they mentioned it is irrelevant in BE/ANDA contecxt …
The FDA? Where?
❝ … some academic curiosity folks keep brining this topic and keep the topic alive.
On the the contrary. Not a single publication; only problems with some regulators.
Expecting that groups could differ in their PK responses is beyond – not only my – intellectual reach. Can one reasonably assume that a study performed in the same CRO, same in-/exclusion criteria (→ similar demographics), quite often groups separated by only a couple of days, samples analyzed with the same bioanalytical method in the same lab, in a crossover each subject acting as its own reference, have an effect on the response variable‽ Of course, not. IMHO, assuming the opposite is an insult to the mind.

Remember the FDA’s slogan back in the day?
In God we trust;
all others must bring data.

Easy. See this post.
