Dear Ankit Parikh,

❝ Question: To address the challenges related to retention of cancer patients in PK BE study, we want to plan 2-period full replicate design. Will the EMA accept this approach for Immediate Release (IR) formulation?

Do you mean 2-period or 4-period design? I.e., do you mean 2 PK days (once T and once R) or 4 PK days (twice T and twice R)?

❝ So, based on our interpretation this will be TTRR or RRTT design.

Did you then use this 4-period replicate desing with 4 PK days?

❝ As per the published EMA Public Assessment Report (EPARs), there are few products approved by EMA using this approach such as Bupropion and Felodipine modified release formulations.

I was looking for these EPARs but could not find them. Could you please share them?
