Dear Martin!

❝ according to my point of view you have to define of a full analysis data set (FADS) and a per-protocol analysis data set (PADS) according to ICH E9.

❝ for FADS you have to analyze the data as they are whereas for the PADS you can specify exclusion/inclusion criteria […]



[image]To quote ICH E9 (Section 5.3):

If no procedure for dealing with outliers was foreseen in the trial protocol, one analysis with the actual values and at least one other analysis eliminating or reducing the outlier effect should be performed and differences between their results discussed.” (my emphasis in blue)


Reading the Q&A document quoted by ElMaestro in his post again I’m getting the impression members of the CHMP/PK group don’t (want to?) know this guideline…

If I anticipated events and stated a decision-tree in the protocol, there’s no need to come up with two bloody evaluations.
To quote from the movíe ‘Highlander’:

There can be only one!

What's the full data set if a subject comes up with a zero response after the reference formulation?
Is T/R of this subject ‘infinity’ or only ‘undefined’? Ask a mathematician.
My kind of software simply cannot deal with such a value…

The quality of responses received is directly proportional to the quality of the question asked. 🚮

rigidly accurate in observation, and
merciless to fallacy in logic.    Thomas Henry Huxley
