Hi John,
Yes, that’s a nice one! Currently for EMA BE of MR products has to be demonstrated both after SD and in steady state. Paixão et al.* showed that for drugs with linear PK Cτ is predictive of steady state. We will see whether the mighty oracle will accept this approach and drop the requirement of MD studies in the final guideline.
❝ Compare the concentration at 24 hours (or the dosing interval for the product) between the test and reference.
