Dear Helmut and Jagankm,

❝ According to current thinking of EMA1,2 (internal draft #8 of the MR-GL as of May 2011) steady state studies will not have to be performed any more – if no accumulation is demonstrated in the single dose study (AUCt/AUC > 80%).


Maybe, but it will take another couple of years before the draft is published for 6-month consultation, comments are received, a final version gets adopted and it comes into force. Until then the current guidance remains applicable... I would say the attitude depends on how critical this project is for your company, how much time you are ready to spend in discussions with various Agencies, in which EU Member State you plan to submit your dossier and when. If you want to be on the safe side, running the steady state study is expensive and may not sound scientifically necessary, but it may in the end be faster and with a more certain result.

Medical researches can be divided into two sorts:
those who think that meta is better and those
who believe that pooling is fooling.    Stephen Senn
