 Fixed Dose combination (FDC) [Design Issues]

Dear HS
We are planning for a dossier submission of a FDC to europe. It has three strengths - 80+12.5, 160+12.5 & 160+25. In this If I plan a study on 160+25, can I get a waiver for the other two strengths.
All these strengths have qualitatively same composition and dose-weight proportionate, except the 160+12.5, where it is not. Should I do an additional study on this strength?

 Fixed Dose combination (FDC)

Dear drplacebo,

Proportionality of the formulation is only one of the criteria listed in section 5.4 of the EU Note for Guidance. Please also note that depending on the (non-)linearity of the PK of the two active substances you may have to conduct your trial using the 80 + 12.5 formulation and not on the 160 + 25 formulation (see section 9 of the Q&A document for additional detail).

Unless you meet the "5 % rule" in bullet 4 of section 5.4 of the Note for Guidance, you will have to perform also a trial on the 160 + 12.5 formulation.

Regards
Ohlbe
