Hi,

I would like to estimate a sample size for a PK linearity study.
The study design plans to test 4 different doses (10, 20, 30 and 40).
I need to test the bioequivalence for each dose, compared to the reference dose which is 20. In addition I need to calculate the linear correlation slope for the four doses, a deviation of 20% between doses being acceptable.

What is the required methodology and what is the formula to calculate the sample size?

Regards,

Kro
