Hi, as per my knowledge..there shd be nothing like a standard PK/PD protocol. You have to design yourself based on the molecule (small/large), may be you can first go through some available studies of other molecules of similar class to have an idea about Tmax and Half-life to fix the time-points.. Although the PK properties of your molecule can be quite different from the same class, but you can use the results from your initial study, to plan a throrough study later on or integrate other parameters along with.
Anukana Bhattacharjee kindly inform what are you working with small/large molecule, and better to provide some precise details. So, that I can send you relevant info.
