Dear ElMaestro,

Thank you for your input. I agree that this rule would punish sponsors have high sample sizes.

I understand this is also a potential mechanism of abuse to get poor drugs approved: Sponsors may increase sample sizes arbitrarily to meet BE. Would my proposed approach prevent that?

Lets take a drug that comes in 100, 112, and 125. Theoretically, a sponsor could get 100, 112, AND 125 dosage forms (assuming CMC doesn't catch it) approved for 112 if they use sample sizes big enough This is my biggest concern.

Thanks again for your input -
