Hi everyone!  During a Phase I bioequivalence trial of a TDDS, we recorded the adhesion of the patches (T and R), at the end of dosing interval, as percentage of area that remains adhered, according to EMA's Guideline. I ask if anyone could advise me on how to perform a non-inferiority analysis for this data, on Phoenix WinNonlin. Many thanks in advance! Sara Edit: Category changed; see also this post #1.

Hi Sara, sorry for not replying earlier. » […] how to perform a non-inferiority analysis for this data, on Phoenix WinNonlin. Not directly supported in Phoenix. However, there is a simple workaround. Non-inferiority tests (and non-superiority as well) are one-sided. Perform the BE-analysis as usual in Phoenix (i.e., two-sided for equivalence at α 0.05) and assess whether the lower confidence limit is ≥80.00% of the reference. Ignore the upper limit. — Dif-tor heh smusma 🖖 Helmut Schütz ![[image]](https://static.bebac.at/img/CC by.png) The quality of responses received is directly proportional to the quality of the question asked. 🚮 Science Quotes |

Hi Helmut, Thank you so much for your answer! Regarding the fixed and random effects, do you have any recommendation? Should we use all effects fixed as for PK BE analysis; or only Subject and Treatment fixed as when comparing irritation scores? Thank you once again! Sara — Sara |

Hi Sara, » Regarding the fixed and random effects, do you have any recommendation? Should we use all effects fixed as for PK BE analysis; Since the PKWP seemingly is obsessed with “all effects fixed”, likely yes.  — Dif-tor heh smusma 🖖 Helmut Schütz The quality of responses received is directly proportional to the quality of the question asked. 🚮 Science Quotes |
