Replicate Pilot study [Power / Sample Size]
Hi again Kumar Naidu,
Difficult. I would at least try to read up on Drugs@FDA and see if there have been some formulation changes since the 1992 approval. But trouble is, the immediately available reviews generally do not date all the way back to that time, if I recall correctly. So you may be a little in the dark. Paper-based FoI might be an option, I can't tell.
Sometimes yes. But depends on the type of formulation and on excipients. Regulators would probably say it depends somehow on proportionality of the formulations as well.
❝ I want to know that how far it is right to correlate the values of the PK parameters mentioned in the literature for the RLD at the time of its approval (say approved in 1992) to the present day values of the RLD observed in the recent studies, especially when the drug is high variable.

❝ Also can we correlate PK parameters of Drug A 250mgx2 with Drug A 500mgx1 if the drug is non-linear.
